Question

I want to select multiple tables with MySQL.
But I don’t know exactly the name of them, but they have all the same structure.

For example:

table_345:
id || row_1 || row_2 || row_3

I want to have something like that:

SELECT `id` FROM table_*

Answer 1

If you are using PHP with your MySQL database you can use mysql_list_tables() to get the list of tables in your database. That list can then be filtered easily using strpos(). Once you have your list of tables, you can use SQL UNION to combine the result sets from your tables.

I hope there’s a really good reason for you to choose this kind of design since it could get really ugly, really fast.

Good luck.
