How to Use Variables Inside MySQL's Limit Clause Safely Using Prepared Statements or Stored Programs
Understanding Limit Clause with Variables in MySQL In this article, we’ll explore how to use a set variable inside the LIMIT clause in MySQL. We’ll delve into why you can’t simply pass a variable value directly into the LIMIT clause and discuss alternative methods for achieving this.
The Issue with Direct Variable Use Let’s examine the provided SQL query:
SET @UPPER := (SELECT ROUND(COUNT(LONG_W)/2) FROM STATION); SELECT LONG_W FROM STATION ORDER BY LONG_W DESC LIMIT @UPPER; Here, we first set a variable @UPPER to half of the total count of rows in the STATION table.
