 A query like `SELECT` or `DESCRIBE` returns a value, and so you have to use a `_store` or `_use` query functions, which return `SQL_RES*`. The `_use` version streams the result from the SQL server, and is not usually what you want. Only use `_use` if you have some stupidly big query result that won't fit in memory. The `_store` versions stores the result - this has the advantage you can see how many rows there are `sql_num_rows(res)` and it frees the `SQL` handle to allow other queries even when working through the rows of the result. You free the result with `sql_free_result(res)`. The `_safe` version always returns an `SQL_RES*` or errors, the non `_safe` returns NULL if error.
