转换失败

Question

我在尝试运行SQL查询时遇到此问题。无法弄清楚转换到＆＃34; int＆＃34;正在发生。有人可以指出我正确的方向吗？

SELECT  TOP 100 PERCENT 
        a.S1 as "SegNumber", 
        a.S2 as "SegmentName", 
        a.S3 as "Description",
        a.S4 as "SegmentValue" 
FROM
( 
    SELECT      3 as "S1", 
                LTRIM(RTRIM(b.SUMMARY_ACCT)) + '_' + 'Accounts' as "S2", 
                b.ACCOUNT_DESC as "S3", 
                '^' + LTRIM(RTRIM(c.SUMMARY_ACCT)) + '_' + 'Accounts' as "S4" 
    FROM        TEST.dbo.GLCHARTSUM b 
    inner join  TEST.dbo.GLCHARTSUM c   ON  c.PARENT_OBJ_ID = b.SUMRY_ACCT_ID 
    UNION ALL 
    SELECT      3 as "S1", 
                LTRIM(RTRIM(c.SUMMARY_ACCT)) + '_' + 'Accounts' as "S2", 
                c.ACCOUNT_DESC as "S3", 
                LTRIM(RTRIM(convert(varchar(100),b.ACCOUNT))) as "S4" 
    FROM        TEST.dbo.GLCHARTDTL b 
    INNER JOIN  TEST.dbo.GLCHARTSUM c   ON  c.SUMRY_ACCT_ID = b.SUMRY_ACCT_ID 
    UNION ALL 
    SELECT      2 as "S1", 
                LTRIM(RTRIM(ACCT_UNIT)) + '_' + 'Unit' as "S2" , 
                DESCRIPTION as "S3", 
                '^' + LTRIM(RTRIM(ACCT_UNIT)) + '_Unit' as "S4" 
    FROM        TEST.dbo.GLNAMES 
    WHERE       POSTING_FLAG ='S' 
    UNION ALL 
    SELECT      2 as "S1", 
                LTRIM(RTRIM(ACCT_UNIT)) + '_' + 'Unit' as "S2", 
                DESCRIPTION as "S3", 
                LTRIM(RTRIM(ACCT_UNIT)) as "S4" 
    FROM        TEST.dbo.GLNAMES 
    WHERE       POSTING_FLAG ='P'
    UNION ALL 
    SELECT      3 as "S1", 
                MATRIX_CAT + Substring(MX_VALUE,1,5) AS "S2", 
                MX_VALUE as "S3", 
                ACCOUNT AS "S4" 
    FROM        TEST.dbo.GLACCMXVAL b 
    INNER JOIN  TEST.dbo.GLCHARTDTL c   ON  b.OBJ_ID = c.OBJ_ID 
) a 
WHERE   1 = 1 
ORDER BY a.S2

错误：

  

Msg 245，Level 16，State 1，Line 1
  转换varchar值时转换失败＆＃39; ^ ASSETS_Accounts＆＃39;数据类型int。

Answer 1

您之前看到此错误的原因是您上一次UNION ALL。 ACCOUNT值为INT，但其他S4列为VARCHAR。

您应该将ACCOUNT列投放到VARCHAR

...
UNION ALL 
SELECT      3 as "S1", 
            MATRIX_CAT + Substring(MX_VALUE,1,5) AS "S2", 
            MX_VALUE as "S3", 
            CONVERT(VARCHAR (100), ACCOUNT)  AS "S4" 
...
