Method Detail

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.

parseIdentifier

public org.apache.flink.table.catalog.UnresolvedIdentifier parseIdentifier(String identifier)

Specified by:

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

parseSqlExpression

public org.apache.flink.table.expressions.ResolvedExpression parseSqlExpression(String sqlExpression,
                                                                                org.apache.flink.table.types.logical.RowType inputRowType,

getCompletionHints

public String[] getCompletionHints(String statement,
                                   int cursor)

Specified by:
