MySQL 错误 - 理解它

Question

有没有人见过这种错误以及它的含义？

我有一个存储过程，它只是在 502 条记录中运行游标，当它通过循环时，插入到表中，本质上是复制和粘贴，但它只输入 239 条记录，我得到这个错误

1265 Data truncated for column 'v_tagMemberSF' at row 5 
 1265 Data truncated for column 'v_tagMemberSF' at row 6 
 1265 Data truncated for column 'v_tagMemberSF' at row 7
 1265 Data truncated for column 'v_tagMemberSF' at row 10 
 1265 Data truncated for column 'v_tagMemberSF' at row 11 
 1265 Data truncated for column 'v_tagMemberSF' at row 12 
 1265 Data truncated for column 'v_tagMemberSF' at row 13 
 1265 Data truncated for column 'v_tagMemberSF' at row 14

带有光标的存储过程是

OPEN cur1;

    -- Start the Loop --
    dataSetLoop: LOOP

    -- get the values of each column into our variables declared in stored procedure

            FETCH cur1 INTO v_dateTime, v_val, v_numIndex, v_tagName, v_tagIndex, v_tagMemberSF, v_tagMemberMinVal, v_tagMemberMaxVal;

            if v_tagMemberSF = NULL then
            SET v_tagMemberSF = 1;
            END IF;

            -- Check if v_val is null first --
            INSERT INTO new_tempdata.looper (incremented, TagNameInserted) VALUES (v_dateTime, v_tagName);
            COMMIT;
            IF done THEN
                LEAVE dataSetLoop;
            END IF;


        END LOOP dataSetLoop;

    CLOSE cur1;

INSERT INTO new_tempdata.looper (incremented, TagNameInserted) Values (123456789,'ID29SP');

END

有人知道这可能会做什么吗？

Answer 1

此错误意味着您的 new_tempdata.looper 表无法存储您尝试插入的数据。检查字段incremented和TagNameInserted的长度，必须与v_dateTime和v_tagName相同；
