MySQL Syntax Check

Mabilis na online na pagsusuri ng SQL syntax sa iyong browser.

I-paste ang isang SQL query at mag-run ng mabilis na syntax sanity check — hinahanap nito ang balanseng mga panipi at panaklong, mga trailing comma, at isang makilalang hugis ng pahayag. Ito ay isang mabilis na sanity check, hindi isang buong MySQL parser o query executor. Hindi ito kumokonekta sa database, kaya ang iyong SQL ay hindi kailanman lumalabas sa iyong browser.

Subukan ang halimbawa:

Ano ang sinusuri nito (at ano ang hindi)

Ang tool na ito ay nagpapatakbo ng mabilis na structural sanity check sa loob ng iyong browser: balanseng mga single quote, double quote, at backtick; balanseng mga panaklong; mga trailing comma bago ang FROM, ), o dulo ng pahayag; kung nagsisimula ang query sa isang kinikilalang keyword; at isang nawawalang trailing semicolon (ipinapakita bilang babala). Hindi nito naiintindihan ang buong MySQL grammar, niva-validate ang mga pangalan ng talahanayan o column, o nag-e-execute ng anuman. Hindi ito kailanman kumokonekta sa isang database, kaya ang iyong SQL ay nananatiling pribado sa pahinang ito.

Frequently Asked Questions

Is this a full MySQL parser or query validator?

No. It is a fast syntax sanity check that looks for balanced quotes and parentheses, trailing commas, and a recognizable statement shape. It does not understand full MySQL grammar, check table or column names, or run your query.

Does my SQL get sent to a server or database?

No. The check runs entirely in your browser using JavaScript. Your SQL never leaves the page and the tool never connects to any database, so it is safe for private queries.

What kinds of problems can it catch?

Empty input, unbalanced parentheses, unterminated single quotes, double quotes, or backticks, trailing commas before FROM or a closing parenthesis or the end of the statement, statements that do not start with a recognized keyword, and a missing trailing semicolon (shown as a warning).

It says no problems found — does that mean my query is correct?

Not necessarily. A clean result only means the basic structure looks fine. Logic errors, wrong column names, and dialect-specific issues will not be caught — run the query against your actual database to be certain.
