MySQL Stored procedure won't fetch the whole table?
You can use SELECT *FROM yourTableName in stored procedure. Let us first create a table −
mysql> create table DemoTable654 ( StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,StudentFirstName varchar(100) ); Query OK, 0 rows affected (0.70 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable654(StudentFirstName) values('John');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable654(StudentFirstName) values('Sam');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable654(StudentFirstName) values('Mike');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable654(StudentFirstName) values('Robert');
Query OK, 1 row affected (0.12 sec)Display all records from the table using select statement −
mysql> select *from DemoTable654;
This will produce the following output −
+-----------+------------------+ | StudentId | StudentFirstName | +-----------+------------------+ | 1 | John | | 2 | Sam | | 3 | Mike | | 4 | Robert | +-----------+------------------+ 4 rows in set (0.00 sec)
Following is the query to fetch the records of entire table using stored procedure −
mysql> DELIMITER // mysql> CREATE PROCEDURE getWholeTable() BEGIN SELECT *FROM DemoTable654; END // Query OK, 0 rows affected (0.16 sec) mysql> DELIMITER ;
Now you can call the above stored procedure using call command −
mysql> call getWholeTable();
This will produce the following output −
+-----------+------------------+ | StudentId | StudentFirstName | +-----------+------------------+ | 1 | John | | 2 | Sam | | 3 | Mike | | 4 | Robert | +-----------+------------------+ 4 rows in set (0.08 sec) Query OK, 0 rows affected (0.13 sec)
