020, MySQL create a stored procedure, displaying stored procedures, stored procedure calls, delete stored procedure

First, we create a MySQL storage process, writes the following in the SQL code area, and executed on it

# A stored procedure to write
 the CREATE  PROCEDURE ShowDate () 
 the BEGIN 
        # outputs the current time 
        the SELECT CURDATE ();
 the END ;

Second, we have to call the stored procedure

# Call a stored procedure 
CALL ShowDate ();

After calling effect is as follows

 

 Third, we have to see our stored procedures

# Display stored procedure 
SHOW the CREATE  PROCEDURE ShowDate;

You can see the stored procedures are stored in a field inside the Create Procedure

 

 Fourth, we have to delete the stored procedure

# Delete the stored procedure
 DROP  PROCEDURE ShowDate;

 

 Deleted after not see the stored procedure
