Function ParseTiDBForSyntaxCheck

backend/plugin/parser/tidb/tidb.go:40–59

ParseTiDBForSyntaxCheck parses TiDB SQL for syntax checking purposes. Returns []base.AST with *AST instances. Per-statement parse + line-tracking is delegated to parsePingCapSingleStatement (in dispatcher.go) so the dispatcher's pingcap-fallback path and this canonical pre-flip path produce structu

(statement string)

// signals "non-1 node count, skip" — same semantic as the pre-
// refactor inline `if len(nodes) != 1 { continue }`.
func ParseTiDBForSyntaxCheck(statement string) ([]base.AST, error) {
	singleSQLs, err := base.SplitMultiSQL(storepb.Engine_TIDB, statement)
	if err != nil {
		return nil, err
	}

	var results []base.AST
	for _, singleSQL := range singleSQLs {
		ast, err := parsePingCapSingleStatement(singleSQL)
		if err != nil {
			return nil, err
		}
		if ast == nil {
			continue
		}
		results = append(results, ast)
	}

	return results, nil
}

// applyTiDBLineTracking sets OriginTextPosition on a freshly-parsed pingcap
// node and walks CREATE TABLE columns to set their per-column line numbers
