passing LIMIT as parameters to MySQL sproc
Prior to 5.5.6, LIMIT
could not be parameterized in MySQL stored procedures. You'd need to build the query dynamically and execute it.
In 5.5.6 and above, you can just pass the stored procs parameters as arguments to LIMIT
and OFFSET
as long as they are INTEGER
.
I just found a solution which may be helpful. Use declared variables in your stored procedure and set them to your parameters
eg.
CREATE PROCEDURE MyProcedure(
IN paramFrom INT,
IN paramTo INT
)
BEGIN
DECLARE valFrom INT;
DECLARE valTo INT;
SET valFrom = paramFrom;
SET valTo = paramTo;
SELECT * FROM myTable LIMIT valFrom, valTo;
END
From http://dev.mysql.com/doc/refman/5.1/en/select.html:
The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be nonnegative integer constants (except when using prepared statements).
Here's prepared statement example which might help you:
SET @skip=1;
SET @rows=5;
PREPARE STMT FROM 'SELECT * FROM table LIMIT ?, ?';
EXECUTE STMT USING @skip, @rows;
