Problem creating Stored Procedure in MySQL

Question

I have written the below mentioned script in MySQL to create Stored Procedure:

CREATE PROCEDURE `AddBranch`(
IN `inCompanyCode` char(3), 
IN `inBranchCode` varchar(6), 
IN `inBankBranch` varchar(40)
)
BEGIN
    DECLARE branchExists TINYINT DEFAULT 0;
    SELECT Count(*) INTO branchExists FROM branches WHERE CompanyCode = inCompanyCode AND BranchCode = inBranchCode;
    IF branchExists = 0 THEN
        INSERT INTO branches VALUES (inCompanyCode, inBranchCode, inBankBranch);
    ELSE
        UPDATE branches SET Branch = inBankBranch
        WHERE CompanyCode = inCompanyCode AND BranchCode = inBranchCode;
    END IF;
END;

While running the query, the error message displayed is:

1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 7

I have even tried DECLARE branchExists TINYINT(1) DEFAULT 0; but the problem persists.

What is wrong with line 7?

• You need to redefine Delimiter to something else (eg: $$), instead of (;).
• Also as a safety measure, check if the same name procedure already exists or not (DROP PROCEDURE IF EXISTS)
• At the end, redefine the DELIMITER to ;

Change the stored procedure to as follows:

DELIMITER $$
DROP PROCEDURE IF EXISTS `AddBranch`$$

CREATE PROCEDURE `AddBranch`(
IN `inCompanyCode` char(3), 
IN `inBranchCode` varchar(6), 
IN `inBankBranch` varchar(40)
)
BEGIN
    DECLARE branchExists TINYINT DEFAULT 0;
    SELECT Count(*) INTO branchExists FROM branches WHERE CompanyCode = inCompanyCode AND BranchCode = inBranchCode;
    IF branchExists = 0 THEN
        INSERT INTO branches VALUES (inCompanyCode, inBranchCode, inBankBranch);
    ELSE
        UPDATE branches SET Branch = inBankBranch
        WHERE CompanyCode = inCompanyCode AND BranchCode = inBranchCode;
    END IF;
END$$

DELIMITER ;
