获取错误代码:1292 在存储过程中截断了不正确的 DOUBLE 值? [英] getting Error Code: 1292 Truncated incorrect DOUBLE value in stored procedure?

问题描述

我正在写一个程序 -

DELIMITER $$

USE `genome`$$

DROP PROCEDURE IF EXISTS `get_family`$$

CREATE DEFINER=`root`@`localhost` PROCEDURE `get_family`(p_h INT(10))
BEGIN
    DECLARE rv,q,queue,queue_children VARCHAR(1024);
    DECLARE queue_length,front_id,pos INT;

        SET rv = '';
    SET queue = p_h;
    SET queue_length = 1;

    WHILE queue_length > 0 DO
        SET front_id = FORMAT(queue,0);

        IF queue_length = 1 THEN
            SET queue = '';
        ELSE
            SET pos = LOCATE(',',queue) + 1;
            SET q = SUBSTR(queue,pos);
            SET queue = q;
        END IF;
        SET queue_length = queue_length - 1;

        SELECT IFNULL(qc,'') INTO queue_children
        FROM (SELECT GROUP_CONCAT(id) qc
        FROM folder WHERE parent = front_id) A;

        IF LENGTH(queue_children) = 0 THEN
            IF LENGTH(queue) = 0 THEN
                SET queue_length = 0;
            END IF;
        ELSE
            IF LENGTH(rv) = 0 THEN
                SET rv = queue_children;
            ELSE
                SET rv = CONCAT(rv,',',queue_children);
            END IF;
            IF LENGTH(queue) = 0 THEN
                SET queue = queue_children;
            ELSE
                SET queue = CONCAT(queue,',',queue_children);
            END IF;
            SET queue_length = LENGTH(queue) - LENGTH(REPLACE(queue,',','')) + 1;
        END IF;
    END WHILE;

   SELECT rv FROM DUAL;

END$$

DELIMITER ;

它成功了，但是当我调用 proc 时，它给了我错误 -

It succeeded, but when I am calling the proc, it gives me error -

call get_family(117);
Error Code: 1292
Truncated incorrect DOUBLE value: '118,119,120,124'

但是当我在程序中传递相同的 116 时，它工作正常.我哪里做错了.请告诉我.

But when i am passing the same 116 in the procedure, its working fine. Where i am doing wrong. Please let me know.

推荐答案

好的，我找到了解决方案.

Ok I got the solution.

我只是将 varchar(我认为输出很长)类型更改为顶部的文本，现在它可以正常工作了.

I simply changed the varchar(output was long i think) type to text on the top, now its working properly.
