Package org.apache.flink.sql.parser.dql

Class SqlRichDescribeModel

  • All Implemented Interfaces:
    Cloneable
    public class SqlRichDescribeModel
extends org.apache.calcite.sql.SqlCall
    DESCRIBE MODEL [EXTENDED] [[catalogName.] dataBasesName].sqlIdentifier sql call. Here we add Rich in className to follow the convention of SqlDescribeTable, which only had it to distinguish from calcite's original SqlDescribeTable, even though calcite does not have SqlDescribeModel.
