Returns:

this CREATE statement.

addColumn

public T addColumn(String columnName,
          DataType dataType)

Add a column definition to this CREATE statement.

To add a list column:

     addColumn("myList",DataType.list(DataType.text()))
 

To add a set column:

Parameters:

columnName - the name of the column to be added.

dataType - the data type of the column to be added.

Returns:

this CREATE statement.

addUDTColumn

public T addUDTColumn(String columnName,
             UDTType udtType)

Add a column definition to this CREATE statement, when the type contains a UDT.

Parameters:

columnName - the name of the column to be added.

udtType - the UDT type of the column to be added. Use SchemaBuilder.frozen(String) or SchemaBuilder.udtLiteral(String).

Returns:

this CREATE statement.

addUDTListColumn

public T addUDTListColumn(String columnName,
                 UDTType udtType)

Shorthand to add a column definition to this CREATE statement, when the type is a list of UDT.

Parameters:

columnName - the name of the column to be added

udtType - the udt type of the column to be added. Use SchemaBuilder.frozen(String).

Returns:

this CREATE statement.

addUDTSetColumn

public T addUDTSetColumn(String columnName,
                UDTType udtType)

Shorthand to add a column definition to this CREATE statement, when the type is a set of UDT.

Parameters:

columnName - the name of the column to be added

udtType - the udt type of the column to be added. Use SchemaBuilder.frozen(String).

Returns:

this CREATE statement.

addUDTMapColumn

public T addUDTMapColumn(String columnName,
                DataType keyType,
                UDTType valueUdtType)
