Use IN() to get only a particular record in a MySQL stored procedure?
Let us first create a table −
mysql> create table DemoTable2004 ( UserId varchar(20), UserName varchar(20) ); Query OK, 0 rows affected (0.57 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable2004 values('John_123','John');
Query OK, 1 row affected (0.93 sec)
mysql> insert into DemoTable2004 values('23456_Carol','Carol');
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable2004 values('111_Bob','Bob');
Query OK, 1 row affected (0.14 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable2004;
This will produce the following output −
+-------------+----------+ | UserId | UserName | +-------------+----------+ | John_123 | John | | 23456_Carol | Carol | | 111_Bob | Bob | +-------------+----------+ 3 rows in set (0.00 sec)
Here is the query to create a stored procedure and select only a particular record with IN() −
mysql> delimiter //
mysql> create procedure test_of_in(IN uId varchar(20))
BEGIN
select * from DemoTable2004 where UserId IN(uId);
END
//
Query OK, 0 rows affected (0.15 sec)
mysql> delimiter ;
Call the stored procedure:
mysql> call test_of_in('23456_Carol');
This will produce the following output −
+-------------+----------+ | UserId | UserName | +-------------+----------+ | 23456_Carol | Carol | +-------------+----------+ 1 row in set (0.00 sec) Query OK, 0 rows affected, 1 warning (0.02 sec)
