Which hash function to choose for query naming?

Question

PHP

Good afternoon.
I have a wonderful class in PHP for working with parameterized Postgre prepared queries
like pgdb::getAll('query_name', 'query_text', $paramsArray);
The name of the query is, of course, useful in places, but now I'm running a rather thick and bold project with a bunch of dynamic queries, and the names interfere quite a lot in places. From here came the decision to replace (if not specified) the query name with a non-hash of the query text.
Please advise what to use? query length from simple 'select 1 from table' to monsters for 5 pages a4

Answer 1

MD5 - fast and easy, SHA1 - less collisions.

Answer 2

md5 is enough.

Answer 3

It's not clear why you need a query name.
I so understand, what for repeated start of already prepared request?
And how many such requests do you have for the application?
They, in fact, should not exist at all, and for those units that can be found, the game is not worth the candle.
