QueryRequest (AWS Java SDK for Amazon DynamoDB 1.9.17 API)

java.lang.Object
- com.amazonaws.AmazonWebServiceRequest

All Implemented Interfaces:

Serializable
```
public class QueryRequest
extends com.amazonaws.AmazonWebServiceRequest
implements Serializable
```
Container for the parameters to the Query operation.
A Query operation directly accesses items from a table using the table primary key, or from an index using the index key. You must provide a specific hash key value. You can narrow the scope of the query by using comparison operators on the range key value, or on the index key. You can use the ScanIndexForward parameter to get results in forward or reverse order, by range key or by index key.

Queries that do not return results consume the minimum number of read capacity units for that type of read operation.

If the total number of items meeting the query criteria exceeds the result set size limit of 1 MB, the query stops and results are returned to the user with LastEvaluatedKey to continue the query in a subsequent operation. Unlike a Scan operation, a Query operation never returns both an empty result set and a LastEvaluatedKey . The LastEvaluatedKey is only provided if the results exceed 1 MB, or if you have used Limit .

You can query a table, a local secondary index, or a global secondary index. For a query on a table or on a local secondary index, you can set ConsistentRead to true and obtain a strongly consistent result. Global secondary indexes support eventually consistent reads only, so do not specify ConsistentRead when querying a global secondary index.

    Returns:
    A reference to this updated object so that method calls can be chained together.
  - getSelect
```
public String getSelect()
```
    The attributes to be returned in the result. You can retrieve all item attributes, specific item attributes, the count of matching items, or in the case of an index, some or all of the attributes projected into the index.
    - ALL_ATTRIBUTES - Returns all of the item attributes from the specified table or index. If you query a local secondary index, then for each matching item in the index DynamoDB will fetch the entire item from the parent table. If the index is configured to project all item attributes, then all of the data can be obtained from the local secondary index, and no fetching is required.
    - ALL_PROJECTED_ATTRIBUTES - Allowed only when querying an index. Retrieves all attributes that have been projected into the index. If the index is configured to project all attributes, this return value is equivalent to specifying ALL_ATTRIBUTES.
    - COUNT - Returns the number of matching items, rather than the matching items themselves.
    - SPECIFIC_ATTRIBUTES - Returns only the attributes listed in AttributesToGet. This return value is equivalent to specifying AttributesToGet without specifying any value for Select.
      If you query a local secondary index and request only attributes that are projected into that index, the operation will read only the index and not the table. If any of the requested attributes are not projected into the local secondary index, DynamoDB will fetch each of these attributes from the parent table. This extra fetching incurs additional throughput cost and latency.
      If you query a global secondary index, you can only request attributes that are projected into the index. Global secondary index queries cannot fetch attributes from the parent table.
    If neither Select nor AttributesToGet are specified, DynamoDB defaults to ALL_ATTRIBUTES when accessing a table, and ALL_PROJECTED_ATTRIBUTES when accessing an index. You cannot use both Select and AttributesToGet together in a single request, unless the value for Select is SPECIFIC_ATTRIBUTES. (This usage is equivalent to specifying AttributesToGet without any value for Select.)
    Constraints:
    Allowed Values: ALL_ATTRIBUTES, ALL_PROJECTED_ATTRIBUTES, SPECIFIC_ATTRIBUTES, COUNT
    Returns:
    The attributes to be returned in the result. You can retrieve all item attributes, specific item attributes, the count of matching items, or in the case of an index, some or all of the attributes projected into the index.

    Allowed Values: ALL_ATTRIBUTES, ALL_PROJECTED_ATTRIBUTES, SPECIFIC_ATTRIBUTES, COUNT
    Parameters:
    select - The attributes to be returned in the result. You can retrieve all item attributes, specific item attributes, the count of matching items, or in the case of an index, some or all of the attributes projected into the index.
    
    ALL_ATTRIBUTES - Returns all of the item attributes from the specified table or index. If you query a local secondary index, then for each matching item in the index DynamoDB will fetch the entire item from the parent table. If the index is configured to project all item attributes, then all of the data can be obtained from the local secondary index, and no fetching is required.
    
    ALL_PROJECTED_ATTRIBUTES - Allowed only when querying an index. Retrieves all attributes that have been projected into the index. If the index is configured to project all attributes, this return value is equivalent to specifying ALL_ATTRIBUTES.
    
    COUNT - Returns the number of matching items, rather than the matching items themselves.
    
    SPECIFIC_ATTRIBUTES - Returns only the attributes listed in AttributesToGet. This return value is equivalent to specifying AttributesToGet without specifying any value for Select.
    If you query a local secondary index and request only attributes that are projected into that index, the operation will read only the index and not the table. If any of the requested attributes are not projected into the local secondary index, DynamoDB will fetch each of these attributes from the parent table. This extra fetching incurs additional throughput cost and latency.
    If you query a global secondary index, you can only request attributes that are projected into the index. Global secondary index queries cannot fetch attributes from the parent table.
    
    If neither Select nor AttributesToGet are specified, DynamoDB defaults to ALL_ATTRIBUTES when accessing a table, and ALL_PROJECTED_ATTRIBUTES when accessing an index. You cannot use both Select and AttributesToGet together in a single request, unless the value for Select is SPECIFIC_ATTRIBUTES. (This usage is equivalent to specifying AttributesToGet without any value for Select.)
    Returns:
    A reference to this updated object so that method calls can be chained together.

  - getKeyConditions
```
public Map<String,Condition> getKeyConditions()
```
    The selection criteria for the query. For a query on a table, you can have conditions only on the table primary key attributes. You must specify the hash key attribute name and value as an EQ condition. You can optionally specify a second condition, referring to the range key attribute.
    If you do not specify a range key condition, all of the items that match the hash key will be retrieved. If a FilterExpression or QueryFilter is present, it will be applied after the items are retrieved.
    For a query on an index, you can have conditions only on the index key attributes. You must specify the index hash attribute name and value as an EQ condition. You can optionally specify a second condition, referring to the index key range attribute.
    Each KeyConditions element consists of an attribute name to compare, along with the following:
    
    AttributeValueList - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the ComparisonOperator being used.
    For type Number, value comparisons are numeric.
    String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.
    For Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.
    
    ComparisonOperator - A comparator for evaluating attributes, for example, equals, greater than, less than, and so on.
    For KeyConditions, only the following comparison operators are supported:
    EQ | LE | LT | GE | GT | BEGINS_WITH | BETWEEN
    The following are descriptions of these comparison operators.
    
    EQ : Equal.
    AttributeValueList can contain only one AttributeValue of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.
    
    LE : Less than or equal.
    AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
    
    LT : Less than.
    AttributeValueList can contain only one AttributeValue of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
    
    GE : Greater than or equal.
    AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
    
    GT : Greater than.
    AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
    
    BEGINS_WITH : Checks for a prefix.
    AttributeValueList can contain only one AttributeValue of type String or Binary (not a Number or a set type). The target attribute of the comparison must be of type String or Binary (not a Number or a set type).
    
    BETWEEN : Greater than or equal to the first value, and less than or equal to the second value.
    AttributeValueList must contain two AttributeValue elements of the same type, either String, Number, or Binary (not a set type). A target attribute matches if the target value is greater than, or equal to, the first element and less than, or equal to, the second element. If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not compare to {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}

    AttributeValueList - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the ComparisonOperator being used.
    For type Number, value comparisons are numeric.
    String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.
    For Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.
    
    ComparisonOperator - A comparator for evaluating attributes, for example, equals, greater than, less than, and so on.
    For KeyConditions, only the following comparison operators are supported:
    EQ | LE | LT | GE | GT | BEGINS_WITH | BETWEEN
    The following are descriptions of these comparison operators.
    
    EQ : Equal.
    AttributeValueList can contain only one AttributeValue of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.
    
    LE : Less than or equal.
    AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
    
    LT : Less than.
    AttributeValueList can contain only one AttributeValue of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.

Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.
    
    BEGINS_WITH : Checks for a prefix.
    AttributeValueList can contain only one AttributeValue of type String or Binary (not a Number or a set type). The target attribute of the comparison must be of type String or Binary (not a Number or a set type).
    
    BETWEEN : Greater than or equal to the first value, and less than or equal to the second value.
    AttributeValueList must contain two AttributeValue elements of the same type, either String, Number, or Binary (not a set type). A target attribute matches if the target value is greater than, or equal to, the first element and less than, or equal to, the second element. If an item contains an AttributeValue element of a different type than the one specified in the request, the value does not match. For example, {"S":"6"} does not compare to {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}

```
public Map<String,Condition> getQueryFilter()
```
    There is a newer parameter available. Use FilterExpression instead. Note that if you use QueryFilter and FilterExpression at the same time, DynamoDB will return a ValidationException exception.
    A condition that evaluates the query results after the items are read and returns only the desired values.
    This parameter does not support attributes of type List or Map.
    A QueryFilter is applied after the items have already been read; the process of filtering does not consume any additional read capacity units.
    If you specify more than one condition in the QueryFilter map, then by default all of the conditions must evaluate to true. In other words, the conditions are ANDed together. (You can use the ConditionalOperator parameter to OR the conditions instead. If you do this, then at least one of the conditions must evaluate to true, rather than all of them.)
    Note that QueryFilter does not allow key attributes. You cannot define a filter condition on a hash key or range key.
    Each QueryFilter element consists of an attribute name to compare, along with the following:
    
    AttributeValueList - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the operator specified in ComparisonOperator.
    For type Number, value comparisons are numeric.
    String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.
    For type Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.
    For information on specifying data types in JSON, see JSON Data Format in the Amazon DynamoDB Developer Guide.
    
    ComparisonOperator - A comparator for evaluating attributes. For example, equals, greater than, less than, etc.

    A condition that evaluates the query results after the items are read and returns only the desired values.
    This parameter does not support attributes of type List or Map.
    A QueryFilter is applied after the items have already been read; the process of filtering does not consume any additional read capacity units.
    If you specify more than one condition in the QueryFilter map, then by default all of the conditions must evaluate to true. In other words, the conditions are ANDed together. (You can use the ConditionalOperator parameter to OR the conditions instead. If you do this, then at least one of the conditions must evaluate to true, rather than all of them.)
    Note that QueryFilter does not allow key attributes. You cannot define a filter condition on a hash key or range key.
    Each QueryFilter element consists of an attribute name to compare, along with the following:
    
    AttributeValueList - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the operator specified in ComparisonOperator.
    For type Number, value comparisons are numeric.
    String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.
    For type Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.
    For information on specifying data types in JSON, see JSON Data Format in the Amazon DynamoDB Developer Guide.
    
    ComparisonOperator - A comparator for evaluating attributes. For example, equals, greater than, less than, etc.
    The following comparison operators are available:
    EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN
    For complete descriptions of all comparison operators, see the Condition data type.

  - getExpressionAttributeNames
```
public Map<String,String> getExpressionAttributeNames()
```
    One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:
    - To access an attribute whose name conflicts with a DynamoDB reserved word.
    - To create a placeholder for repeating occurrences of an attribute name in an expression.
    - To prevent special characters in an attribute name from being misinterpreted in an expression.
    Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:
    - Percentile
    The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, go to Reserved Words in the Amazon DynamoDB Developer Guide). To work around this, you could specify the following for ExpressionAttributeNames:
    - {"#P":"Percentile"}
    You could then use this substitution in an expression, as in this example:
    - #P = :val
    Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.
    For more information on expression attribute names, go to Accessing Item Attributes in the Amazon DynamoDB Developer Guide.
    Returns:
    One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:
