Constructor Detail

SQLServerBulkCopyOptions

public SQLServerBulkCopyOptions()

Initializes an instance of the SQLServerBulkCopySettings class using defaults for all of the settings.

Method Detail

getBatchSize

public int getBatchSize()

Gets the number of rows in each batch. At the end of each batch, the rows in the batch are sent to the server.

Returns:

Number of rows in each batch.

setBatchSize

public void setBatchSize(int batchSize)
                  throws SQLServerException

Sets the number of rows in each batch. At the end of each batch, the rows in the batch are sent to the server.

Parameters:

batchSize - Number of rows in each batch.

Throws:

SQLServerException - If the batchSize being set is invalid.

getBulkCopyTimeout

public int getBulkCopyTimeout()

Gets the number of seconds for the operation to complete before it times out.

Returns:

Number of seconds before operation times out.

setBulkCopyTimeout

public void setBulkCopyTimeout(int timeout)
                        throws SQLServerException

Sets the number of seconds for the operation to complete before it times out.

Parameters:

timeout - Number of seconds before operation times out.

Throws:

SQLServerException - If the batchSize being set is invalid.

isKeepIdentity

public boolean isKeepIdentity()

Indicates whether or not to preserve any source identity values.

Returns:

True if source identity values are to be preserved; false if they are to be assigned by the destination.

setKeepIdentity

public void setKeepIdentity(boolean keepIdentity)

Sets whether or not to preserve any source identity values.

Parameters:

keepIdentity - True if source identity values are to be preserved; false if they are to be assigned by the destination

isKeepNulls

public boolean isKeepNulls()

Indicates whether to preserve null values in the destination table regardless of the settings for default values, or if they should be replaced by default values (where applicable).

Returns:

True if null values should be preserved; false if null values should be replaced by default values where applicable.

setKeepNulls

public void setKeepNulls(boolean keepNulls)

Sets whether to preserve null values in the destination table regardless of the settings for default values, or if they should be replaced by default values (where applicable).

Parameters:

keepNulls - True if null values should be preserved; false if null values should be replaced by default values where applicable.

isTableLock

public boolean isTableLock()

Indicates whether SQLServerBulkCopy should obtain a bulk update lock for the duration of the bulk copy operation.

Returns:

True to obtain row locks; false otherwise.

setTableLock

public void setTableLock(boolean tableLock)

Sets whether SQLServerBulkCopy should obtain a bulk update lock for the duration of the bulk copy operation.

Parameters:

tableLock - True to obtain row locks; false otherwise.

isUseInternalTransaction

public boolean isUseInternalTransaction()

Indicates whether each batch of the bulk-copy operation will occur within a transaction or not.

Returns:

True if the batch will occur within a transaction; false otherwise.

setUseInternalTransaction

public void setUseInternalTransaction(boolean useInternalTransaction)

Sets whether each batch of the bulk-copy operation will occur within a transaction or not.

Parameters:

useInternalTransaction - True if the batch will occur within a transaction; false otherwise.

isCheckConstraints

public boolean isCheckConstraints()

Indicates whether constraints are to be checked while data is being inserted or not.

Returns:

True if constraints are to be checked; false otherwise.

setCheckConstraints

public void setCheckConstraints(boolean checkConstraints)

Sets whether constraints are to be checked while data is being inserted or not.

Parameters:

checkConstraints - True if constraints are to be checked; false otherwise.

isFireTriggers

public boolean isFireTriggers()

Indicates if the server should fire insert triggers for rows being inserted into the database.

Returns:

True triggers are enabled; false otherwise.

setFireTriggers

public void setFireTriggers(boolean fireTriggers)

Sets whether the server should be set to fire insert triggers for rows being inserted into the database.

Parameters:

fireTriggers - True triggers are to be enabled; false otherwise.

isAllowEncryptedValueModifications

public boolean isAllowEncryptedValueModifications()

Indicates if allowEncryptedValueModifications option is enabled or not

Returns:

True if allowEncryptedValueModification is set to true; false otherwise.

setAllowEncryptedValueModifications

public void setAllowEncryptedValueModifications(boolean allowEncryptedValueModifications)

Sets whether the driver would send data as is or would decrypt the data and encrypt it again before sending to SQL Server

Use caution when specifying allowEncryptedValueModifications as this may lead to corrupting the database because the driver does not check if the data is indeed encrypted, or if it is correctly encrypted using the same encryption type, algorithm and key as the target column.

Parameters:

allowEncryptedValueModifications - enables bulk copying of encrypted data between tables or databases, without decrypting the data. Typically, an application would select data from encrypted columns from one table without decrypting the data (the app would connect to the database with the column encryption setting keyword set to disabled) and then would use this option to bulk insert the data, which is still encrypted.
