错误'将数据类型varchar转换为数字时出错' - 创建新表

Question

我有一个表“Table1_201403”，带有1个varchar列'列0'。现在，我想从这个表下面的查询插入必要的数据Master_Table2 -

SELECT '2014/03' AS Period 
    ,ltrim(rtrim(SUBSTRING([Column 0], 1, 12))) AS 'Account' 
    ,cast(ltrim(rtrim(SUBSTRING([Column 0], 17, 2))) + ltrim(rtrim(SUBSTRING([Column 0], 15, 2))) + ltrim(rtrim(SUBSTRING([Column 0], 13, 2))) AS DATE) AS Trans_Date 
    ,CASE 
     WHEN ltrim(rtrim(SUBSTRING([Column 0], 30, 1))) = '-' 
      THEN CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11))) AS DECIMAL)/100) AS DECIMAL(9, 2)) * - 1 
     ELSE CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11))) AS DECIMAL)/100) AS DECIMAL(9, 2)) 
     END AS Amount 
INTO Master_Table2 
FROM Table1_201403 
WHERE SUBSTRING([Column 0], 11, 1) <> 'B' 

当我尝试这样做，我得到的错误“错误转换数据类型为varchar到数字”。

什么可以是一个合适的解决方案。任何帮助将不胜感激。

谢谢。

改性 -

SELECT '2014/03' AS Period 
    ,ltrim(rtrim(SUBSTRING([Column 0], 1, 12))) AS 'GL Account' 
    ,cast(ltrim(rtrim(SUBSTRING([Column 0], 17, 2))) + ltrim(rtrim(SUBSTRING([Column 0], 15, 2))) + ltrim(rtrim(SUBSTRING([Column 0], 13, 2))) AS DATE) AS Trans_Date 
    ,case 
     when ltrim(rtrim(SUBSTRING([Column 0], 30, 1))) = '-' 
           THEN( 
             case when isnumeric(ltrim(rtrim(SUBSTRING([Column 0], 19, 11))))=1 then    
             CAST(CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0],19,11))) AS decimal)/100) AS decimal(9,2)) AS decimal)*-1 
             else 
             CAST(CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0],19,11))) AS decimal)/100) AS decimal(9,2)) AS varchar)*-1 end 
            ) 
           ELSE(

             case when isnumeric(ltrim(rtrim(SUBSTRING([Column 0], 19, 11))))=1 then    
             CAST(CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0],19,11))) AS decimal)/100) AS decimal(9,2)) AS decimal) 
             else 
             CAST(CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0],19,11))) AS decimal)/100) AS decimal(9,2)) AS varchar) end 
            ) 
      END as Amount 
      INTO TABLE2 
FROM TABLE1 
WHERE SUBSTRING([Column 0], 11, 1) <> 'B' 

我尝试使用则IsNumeric逻辑。但无法让代码工作。请看一看。 @AdiŤ

并且，数据使用脚本@t_m是如下得到 -

列0 ValidDecimal 006125 01031400000451745+ JNLCIS批次2014年1月3日ÑBA0119 CL 1个 006125 01031400000212077+ JNLCIS批次01/03/2014 N BA0120 CL​​ 1 006125 01031400000311569+ JNLCIS Batch 01/03/2014 N BA0119 PL 1

Answer 1

您试图将数据从varchar转换为decimal.if数据属于你无法转换为十进制的字符。

use cast() or convert() function 

Answer 2

怀疑Amount逻辑可能返回一些varchar值而不是小数。

运行下面的脚本来检查您的金额逻辑是否正确。运行脚本时，如果一切正常，则不应返回任何记录。

select * 
from 
(
    select '2014/03' as Period, 
    ltrim(rtrim(SUBSTRING([Column 0],1,12))) as 'Account', 
    cast(ltrim(rtrim(SUBSTRING([Column 0],17,2)))+ltrim(rtrim(SUBSTRING([Column 0],15,2)))+ltrim(rtrim(SUBSTRING([Column 0],13,2))) AS DATE) 
    as Trans_Date, 
    ISNUMERIC(case when ltrim(rtrim(SUBSTRING([Column 0],30,1)))='-' then CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0],19,11))) AS decimal)/100) AS decimal(9,2))*-1 
      else CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0],19,11))) AS decimal)/100) AS decimal(9,2)) END) As ValidDecimal 
    from Table1_201403 
    where SUBSTRING([Column 0],11,1) <> 'B' 
) CheckForValidDecimal 
where ValidDecimal = 0 

修改：

运行下面这个脚本来找到你的[专栏0]是不正确的记录。然后，您可以更改您的金额逻辑来解决问题。

select * 
from 
(
    select 
    [Column 0], 
    ISNUMERIC(case when ltrim(rtrim(SUBSTRING([Column 0],30,1)))='-' then CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0],19,11))) AS decimal)/100) AS decimal(9,2))*-1 
      else CAST((CAST(ltrim(rtrim(SUBSTRING([Column 0],19,11))) AS decimal)/100) AS decimal(9,2)) END) As ValidDecimal 
    from Table1_201403 
    where SUBSTRING([Column 0],11,1) <> 'B' 
) CheckForValidDecimal 
where ValidDecimal = 0 

Answer 3

请尝试这种方式

SELECT '2014/03' AS Period 
     ,ltrim(rtrim(SUBSTRING([Column 0], 1, 12))) AS 'Account' 
     ,cast(ltrim(rtrim(SUBSTRING([Column 0], 17, 2))) + ltrim(rtrim(SUBSTRING([Column 0], 15, 2))) + ltrim(rtrim(SUBSTRING([Column 0], 13, 2))) AS DATE) AS Trans_Date 
     ,CASE 
      WHEN ltrim(rtrim(SUBSTRING([Column 0], 30, 1))) = '-' 
       THEN case when isnumeric(case when isnumeric(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)) 
       ))=1 then    
       CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)))AS decimal) else 
       CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)))AS varchar) end)=1 
       then CAST(case when isnumeric(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)) 
       ))=1 then    
       CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)))AS decimal) else 
       CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)))AS varchar) end AS decimal(9,2)) *-1 
       else 
       CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)))AS varchar) 
       ELSE 
        CAST(case when isnumeric(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)) 
       ))=1 then    
       CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)))AS decimal) else 
       CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)))AS varchar) end AS decimal(9,2)) /100 AS DECIMAL 
       else 
       CAST(ltrim(rtrim(SUBSTRING([Column 0], 19, 11)))AS varchar) 
       END 
       INTO Master_Table2 
    FROM Table1_201403 
    WHERE SUBSTRING([Column 0], 11, 1) <> 'B'
