# 2435 Un-Optimized Locate Returns True for Tables with Deleted Rows that Satisfy the Locate

Suppose, say we have two records with value of Col1 = 2. In the below loop Delete should be called twice. But it is getting called after deleting the located records also, which is resulting in the below error:


Debugger Exception Notification


Project Project1.exe raised exception class EDatabaseError with message 'tblMemory: Cannot perform this operation on an empty dataset'. Process stopped. Use Step or Run to continue.

Note : In the above case I have only 2 records, so the table becomes empty with the second Delete.

while tblMemory.Locate('Col1',2,[]) do   //This should return False after deleting the Located records. But it is returning True.
