Declare syntax error in MySQL Workbench?

The DECLARE syntax must between BEGIN and END. The syntax is as follows −

BEGIN
DECLARE yourVariableName1 dataType,
DECLARE yourVariableName2 dataType,
.
.
.
.
END

Here is the query to avoid DECLARE syntax error in MySQL −

mysql> DELIMITER //
mysql> create procedure declare_Demo()
   -> BEGIN
   -> DECLARE Name varchar(100);
   -> SET Name: ='John';
   -> SELECT Name;
   -> END
   -> //
Query OK, 0 rows affected (0.17 sec)
mysql> DELIMITER ;

Call the stored procedure with the help of CALL command. The syntax is as follows −

CALL yourStoredProcedureName();

The query is as follows −

mysql> call declare_Demo();

The following is the output −

+------+
| Name |
+------+
| John |
+------+
1 row in set (0.00 sec)
Query OK, 0 rows affected (0.01 sec)
