Example 1 with OrderByScope

use of org.apache.calcite.sql.validate.OrderByScope in project calcite by apache.

the class SqlAbstractGroupFunction method validateCall.

@Override
public void validateCall(SqlCall call, SqlValidator validator, SqlValidatorScope scope, SqlValidatorScope operandScope) {
    super.validateCall(call, validator, scope, operandScope);
    final SelectScope selectScope = SqlValidatorUtil.getEnclosingSelectScope(scope);
    assert selectScope != null;
    final SqlSelect select = selectScope.getNode();
    if (!validator.isAggregate(select)) {
        throw validator.newValidationError(call, Static.RESOURCE.groupingInAggregate(getName()));
    }
    final AggregatingSelectScope aggregatingSelectScope = SqlValidatorUtil.getEnclosingAggregateSelectScope(scope);
    if (aggregatingSelectScope == null) {
        // We're probably in the GROUP BY clause
        throw validator.newValidationError(call, Static.RESOURCE.groupingInWrongClause(getName()));
    }
    for (SqlNode operand : call.getOperandList()) {
        if (scope instanceof OrderByScope) {
            operand = validator.expandOrderExpr(select, operand);
        } else {
