Method Details

parse

public List<org.apache.flink.table.operations.Operation> parse(String statement)

When parsing statement, it first uses ExtendedParser to parse statements. If ExtendedParser fails to parse statement, it uses the CalciteParser to parse statements.

Specified by:

parse in interface org.apache.flink.table.delegation.Parser

Parameters:

statement - input statement.

Returns:

parsed operations.
