摘要类型 Sum is not appropriate for column of type System.String 错误

Question

每当我尝试运行我的项目时都会收到此错误，尽管该列不是 system.string 类型。我有一个用不同数字以相同方式编码的页面，它不会给我这个错误。这是我的 SQL 字符串：

    MyCompSqlString = "SELECT (KAIPRDDTA.F4102LA.IBPRP6)ColOne, (KAIPRDCOM.F0005.DRDL01)ColTwo, COUNT(KAIPRDDTA.F42119LA.SDSOQS*.01)ColThree, SUM(KAIPRDDTA.F42119LA.SDAEXP*.01*CXCRR)ColFour, count(SDDOC)ColFive, SUM(KAIPRDDTA.F42119LA.SDSOQS*.01)ColSix "
    MyCompSqlString += "FROM KAIPRDDTA.F42119LA, KAIPRDDTA.F55311, KAIPRDCOM.F0005, KAIPRDDTA.F0015, KAIPRDDTA.F4102LA"
    MyCompSqlString += "WHERE DRSY = '41' AND DRRT = '01' AND TRIM(DRKY) = IBPRP6 AND KAIPRDDTA.F42119LA.SDITM = KAIPRDDTA.F4102LA.IBITM AND KAIPRDDTA.F42119LA.SDMCU = KAIPRDDTA.F4102LA.IBMCU AND KAIPRDDTA.F42119LA.SDSLSM = KAIPRDDTA.F55311.TERR AND (KAIPRDDTA.F42119LA.SDIVD >= " & SDJ & ") AND (KAIPRDDTA.F42119LA.SDIVD <= " & EDJ & ") AND "
    MyCompSqlString += "(KAIPRDDTA.F42119LA.SDSLSM > 0) AND (KAIPRDDTA.F42119LA.SDGLC NOT IN ('FT60', 'TXTX', 'IN20', 'INSP', 'INWC', 'INWR', 'INWS','',' ')) AND "
    MyCompSqlString += "(trim(KAIPRDDTA.F42119LA.SDLNTY) NOT IN ('T', 'F', 'TX', 'TA', 'TS', 'RF', 'RP','BC')) AND (KAIPRDDTA.F42119LA.SDNXTR <> '999') AND (KAIPRDDTA.F42119LA.SDDCTO not in ('ST','CR','SR')) "
    MyCompSqlString += "AND (KAIPRDDTA.F55311.VIEWID = '" & MyView & "') AND (SDAN8 <> 24157 and SDAN8 <> 152) AND ((SDTRDJ-1)=CXEFT) AND (SDBCRC=CXCRCD) AND (CXCRDC ='USD')"
    MyCompSqlString += "GROUP BY KAIPRDDTA.F4102LA.IBPRP6, KAIPRDCOM.F0005.DRDL01"

这是我的摘要行：

  <ig:SummaryRow EmptyFooterText="" FormatString=" {1}" ShowSummariesButtons="false">
                <ColumnSummaries>
                    <ig:ColumnSummaryInfo ColumnKey="ColThree">
                        <Summaries>
                            <ig:Summary SummaryType="Sum" />
                        </Summaries>
                    </ig:ColumnSummaryInfo>
                    <ig:ColumnSummaryInfo ColumnKey="ColFour">
                        <Summaries>
                            <ig:Summary SummaryType="Sum" />
                        </Summaries>
                    </ig:ColumnSummaryInfo>
                    <ig:ColumnSummaryInfo ColumnKey="ColFive">
                        <Summaries>
                            <ig:Summary CustomSummaryName="100.00%" />
                        </Summaries>
                    </ig:ColumnSummaryInfo>
                    <ig:ColumnSummaryInfo ColumnKey="ColTwo">
                        <Summaries>
                            <ig:Summary CustomSummaryName="Totals:" />
                        </Summaries>
                    </ig:ColumnSummaryInfo>
                </ColumnSummaries>

有人对我为什么会出现此错误有任何建议吗？如果您需要更多信息，请告诉我，我会更新我的问题。预先感谢您的回复

Answer 1

您有一个群组 NULL。此错误意味着并非所有值都是整数。因此，此查询必须生成 NULL 作为某些行的值。
