Method Details

executeDdl

public void executeDdl(CalcitePrepare.Context context,
 SqlNode node)

Description copied from interface: DdlExecutor

Executes a DDL statement.

The statement identified itself as DDL in the CalcitePrepare.ParseResult.kind() field.

Specified by:

executeDdl in interface DdlExecutor

execute

public void execute(SqlNode node,
 CalcitePrepare.Context context)

Template for methods that execute DDL commands.

The base implementation throws UnsupportedOperationException because a SqlNode is not DDL, but overloaded methods such as public void execute(SqlCreateFoo, CalcitePrepare.Context) are called via reflection.
