MySQL过程中的语法错误

Question

我有以下存储过程：

DELIMITER $$
CREATE PROCEDURE SP_Exclusao_BlocoCeramico (IDBloco BIGINT) 
BEGIN

    DECLARE ResistenciaID BIGINT DEFAULT 0;

    DECLARE curs CURSOR FOR
    (
        SELECT ResistenciaCompressaoBlocoCeramicoId FROM resistenciacompressaoblococeramico WHERE BlocoCeramicoId = IDBloco
    );

    DECLARE EXIT HANDLER FOR SQLEXCEPTION 
    BEGIN
        ROLLBACK;
    END;

    OPEN curs; 
    REPEAT
    FETCH curs INTO ResistenciaID;   

    START TRANSACTION;    
    DELETE FROM relacaoobservacaocompressaoblococeramico WHERE CompressaoBlocoCeramicoId = ResistenciaID;
    DELETE FROM resistenciacompressaoblococeramico WHERE BlocoCeramicoId = IDBloco;    
    DELETE FROM blococeramico WHERE BlocoCeramicoId = IDBloco;

    CLOSE curs;    
    COMMIT;        
END 
$$

当我运行时，它会返回错误： 1064您的SQL语法错误。

我错过了什么？
