Method Detail

ifNotExists

@NonNull
CreateDseFunctionStart ifNotExists()

Adds IF NOT EXISTS to the create function specification. This indicates that the function should not be created if it already exists.

orReplace

@NonNull
CreateDseFunctionStart orReplace()

Adds OR REPLACE to the create function specification. This indicates that the function should replace an existing function with the same name if it exists.

withParameter

@NonNull
CreateDseFunctionStart withParameter(@NonNull
                                              CqlIdentifier paramName,
                                              @NonNull
                                              DataType paramType)

Adds a parameter definition in the CREATE FUNCTION statement.

Parameter keys are added in the order of their declaration.

To create the data type, use the constants and static methods in DataTypes, or SchemaBuilder.udt(CqlIdentifier, boolean).

withParameter

@NonNull
default CreateDseFunctionStart withParameter(@NonNull
                                                      String paramName,

                                                      DataType paramType)

Shortcut for withParameter(CqlIdentifier.asCql(paramName), dataType).

returnsNullOnNull

@NonNull
CreateDseFunctionWithNullOption returnsNullOnNull()

Adds RETURNS NULL ON NULL to the create function specification. This indicates that the body of the function should be skipped when null input is provided.

calledOnNull

@NonNull
CreateDseFunctionWithNullOption calledOnNull()
