Method Detail

ifNotExists

public T ifNotExists()

Add the 'IF NOT EXISTS' condition to this CREATE statement.

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:

 addColumn("mySet",DataType.set(DataType.text()))
 

To add a map column:

 addColumn("myMap",DataType.map(DataType.cint(),DataType.text()))
 

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).
