Create a Stored Procedure with MySQL and set a limit to display only a specific number of records
Let us first create a table −
mysql> create table DemoTable1368 -> ( -> ClientId int, -> ClientName varchar(20) -> ); Query OK, 0 rows affected (0.58 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1368 values(101,'Adam'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable1368 values(102,'Bob'); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable1368 values(103,'John'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1368 values(104,'Sam'); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable1368 values(105,'Mike'); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable1368 values(106,'Carol'); Query OK, 1 row affected (0.11 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1368;
This will produce the following output −
+----------+------------+ | ClientId | ClientName | +----------+------------+ | 101 | Adam | | 102 | Bob | | 103 | John | | 104 | Sam | | 105 | Mike | | 106 | Carol | +----------+------------+ 6 rows in set (0.00 sec)
Following is the query to create a stored procedure and use MySQL LIMIT to limit the number of records to be displayed −
mysql> DELIMITER // mysql> CREATE PROCEDURE limit_Demo(IN limitValue int) -> BEGIN -> DECLARE limValue int; -> SET limValue =limitValue ; -> SELECT * FROM DemoTable1368 LIMIT limValue; -> END -> // Query OK, 0 rows affected (0.17 sec) mysql> DELIMITER ;
Now you can call the stored procedure using call command −
mysql> CALL limit_Demo(3);
This will produce the following output −
+----------+------------+ | ClientId | ClientName | +----------+------------+ | 101 | Adam | | 102 | Bob | | 103 | John | +----------+------------+ 3 rows in set (0.00 sec) Query OK, 0 rows affected (0.03 sec)
