These functions are used to issue queries on a connection. Single queries are made using the drizzle_query function, or you can queue multiple queries and run them concurrently using the other query functions.

drizzle_return_t drizzle_query_run_all | ( | drizzle_st * | drizzle | ) |
Run queries until they are all complete. Returns DRIZZLE_RETURN_OK if all queries complete, even if some return errors. This returns immediately if some other error occurs, leaving some queries unprocessed. You must call drizzle_result_error_code() to check if each query succeeded.
