class SqlArgumentAssignmentOperator extends SqlAsOperator
Operator that assigns an argument to a function call to a particular named parameter.Not an expression; just a holder to represent syntax until the validator has chance to resolve arguments.
Sub-class of
SqlAsOperator
("AS") out of convenience; to be consistent with AS, we reverse the arguments.

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)
