Function validateQuery

backend/plugin/parser/doris/query.go:27–38

validateQuery reports whether the given statement is a read-only query suitable for the SQL editor / data-query path. Decision is AST-based: each parsed top-level statement must be a SELECT, SHOW, DESCRIBE, EXPLAIN, or HELP. Relying on leading-keyword classification alone would mis-accept CTE-prefi

(statement string)

// The (bool, bool, error) return shape matches the bytebase QueryValidator
// contract: (isReadOnly, isExplicitReadOnly, syntaxError).
func validateQuery(statement string) (bool, bool, error) {
	parsed, err := parseDorisSQL(statement)
	if err != nil {
		return false, false, err
	}
	for _, p := range parsed {
		if !isReadOnlyAST(p.Node()) {
			return false, false, nil
		}
	}
	return true, true, nil
}

// isReadOnlyAST returns true when the given top-level AST node represents a
// read-only Doris statement (SELECT family, SHOW, DESCRIBE, EXPLAIN, HELP).
