Method Detail

unparse

public void unparse(SqlWriter writer,
                    SqlCall call,
                    int leftPrec,
                    int rightPrec)

Description copied from class: SqlOperator

Writes a SQL representation of a call to this operator to a writer, including parentheses if the operators on either side are of greater precedence.

The default implementation of this method delegates to SqlSyntax.unparse(org.apache.calcite.sql.SqlWriter, org.apache.calcite.sql.SqlOperator, org.apache.calcite.sql.SqlCall, int, int).

Overrides:

unparse in class SqlOperator

createCall

public SqlCall createCall(SqlLiteral functionQualifier,
                          SqlParserPos pos,
                          SqlNode... operands)

Description copied from class: SqlOperator

Creates a call to this operand with an array of operands.

The position of the resulting call is the union of the pos and the positions of all of the operands.

Overrides:

createCall in class SqlOperator

Parameters:

functionQualifier - function qualifier (e.g. "DISTINCT"), may be

pos - parser position of the identifier of the call

operands - array of operands
