Class ServerDdlExecutor

java.lang.Object

org.apache.calcite.server.DdlExecutorImpl

org.apache.calcite.server.ServerDdlExecutor

All Implemented Interfaces:

org.apache.calcite.server.DdlExecutor, org.apache.calcite.util.ReflectiveVisitor

public class ServerDdlExecutor
extends org.apache.calcite.server.DdlExecutorImpl

Executes DDL commands.

Given a DDL command that is a sub-class of SqlNode, dispatches the command to an appropriate execute method. For example, "CREATE TABLE" (SqlCreateTable) is dispatched to execute(SqlCreateTable, CalcitePrepare.Context).
