# 751 Executing Consecutive Queries that Use Memo Fields in the WHERE Clause Causes Slowdown

---

Just opening and closing two queries in correlative order, with a SQL statement wih several LIKE operators, takes more time every time the sequence is executed.

In my application, the first time I open a query of 500 records it takes 2 seconds. Repeating the closing and opening operations, the same query takes UP TO 20 SECONDS to complete.
