Key unique string prevents duplicate rows
I need your help.
This is my query in mysql.
the composition of the key unique string prevents duplicate rows... the problem is that occurs when double row the query is stopped and error in output... would be possible in case double row delete last double row and not stopped the update query?
SET UniqueString = NULL;
SET UniqueString = TRIM(
REPLACE (LINE_NAME, '`', '')
How can i do it?
