CASE WHEN 中的 BIRT Designer 选择语句

Question

我在 BIRT Designer 4.3.1 中遇到问题，我的脚本中有 SQL 查询。

sqlText = " SELECT MXZINVTRANS.ORGID, MXZINVTRANS.ITEMSETID, MXZINVTRANS.SITEID, MXZINVTRANS.TRANSDATE, MXZINVTRANS.STORELOC, MXZINVTRANS.STORELOC_DESCRIPTION,  "
+ "         MXZINVTRANS.ACTUALDATE, MXZINVTRANS.TOSTORELOC, MXZINVTRANS.MAXTAB, MXZINVTRANS.TRANSGROUP, MXZINVTRANS.DOCUMENT,  "
+ "         MXZINVTRANS.REFDOC, MXZINVTRANS.ITEMNUM, MXZINVTRANS.CONDITIONCODE, MXZINVTRANS.ITEM_DESCRIPTION, MXZINVTRANS.COMMODITYGROUP,  "
+ "         MXZINVTRANS.COMMODITYGROUP_DESCRIPTION, MXZINVTRANS.ISSUEUNIT, MXZINVTRANS.TRANSTYPE, MXZINVTRANS.TRANSTYPE_DESCRIPTION, MXZINVTRANS.QUANTITY,  "

+ "         MXZINVTRANS.SAPLINECOST, MXZINVTRANS.SAPTRANSID, "
//+ "            (case MXZINVTRANS.TRANSTYPE  "
//+ "              WHEN 'RECEIPT' THEN 'Prejem' "
//+ "              WHEN 'RETURN' THEN 'Vrač. na skl.' "
//+ "              WHEN 'ISSUE' THEN 'TOREK' "

+ "             WHEN 'Ident prejema'    THEN (select distinct VENDOR from PO where PO.PONUM=left(MXZINVTRANS.REFDOC, LOCATE('-',MXZINVTRANS.REFDOC)-1)) "
//+ "               WHEN 'Ident vračila' THEN (select distinct NAME from COMPANIES where COMPANIES.COMPANY=(select distinct VENDOR from PO where PO.PONUM=left(MXZINVTRANS.REFDOC, LOCATE('-',MXZINVTRANS.REFDOC)-1) and PO.SITEID=MXZINVTRANS.SITEID)) "

//+ " and invbalances.itemnum = '2000049451' "
//+ " and invbalances.itemnum like '2000000%' "
+ " where 1=1 "

+ " and(( trunc(MXZINVTRANS.TRANSDATE) ) <=  TO_DATE ('" + params["datum_do"] + "','YYYY-MM-DD') and ( trunc(MXZINVTRANS.TRANSDATE) ) >=  TO_DATE ('" + params["datum_od"] + "','YYYY-MM-DD'))"

+ storeroomwhere

+ itemwhere
+ tipwhere


//+ " and invbalances.itemnum ='2000049451' "
//+ " and  siteid='6000'"
//+ " order by po.ponum " 
;

maximoDataSet.setQuery(sqlText);

这可能是主要问题：

+ " WHEN 'Ident prejema'    THEN (select distinct VENDOR from PO where PO.PONUM=left(MXZINVTRANS.REFDOC, LOCATE('-',MXZINVTRANS.REFDOC)-1)) "

首先要解释一下，REFFODC 的值类似于 4500038258-R2-120，使用 LEFT，我得到这个数字 4500038258，我在表 PO 中查看了它，其中等于 PONUM，然后我打印 VENDOR 作为数字 114263 例如.

问题就在这里，这里我有错误，但如果我直接写 MXZINVTRANS.REFDOC 编号 4500038258 则没有错误。另外，如果只打印 REFDOC 值的这个子字符串，我会在报告中得到正确的子字符串并且没有错误，那么问题可能就在这里？

假设您已经转储了生成的 SQL 语句并在 BIRT 之外成功对其进行了测试，请记住，对于每个数据集参数，您都需要在语句中出现相应的绑定变量。

例如，如果您的数据集有 两个 数据集参数，则您恰好需要 两个 绑定变量（语法取决于 DB，JDBC 标准 ? 应该适用于每个数据库。

如果这些数字不匹配，则会导致错误。

我解决了一些问题。它的工作，但我有以下问题：

+ " case " 
+ " WHEN MXZINVTRANS.TOSTORELOC IS NULL "

    + " THEN case WHEN MXZINVTRANS.TRANSTYPE_DESCRIPTION='Izdaja' "
        + " THEN case WHEN MXZINVTRANS.DOCUMENT LIKE '%-%' "
            + " THEN left(MXZINVTRANS.DOCUMENT, LOCATE('-',MXZINVTRANS.DOCUMENT)-1) "
            + " ELSE MXZINVTRANS.DOCUMENT "
        + " END "
    + " END "

    + " THEN case WHEN MXZINVTRANS.TRANSTYPE_DESCRIPTION='Ident prejema' "
        + " THEN (select distinct VENDOR from PO where PO.PONUM=MXZINVTRANS.DOCUMENT) "
    + " END "
    
+ " ELSE "
+ " MXZINVTRANS.TOSTORELOC "
+ " END "
+ " AS TOSTORELOC"

当我这样使用它时会出现错误，当我只使用蓝色圆圈中的代码而没有红色圆圈中的代码时。

+ " case " 
+ " WHEN MXZINVTRANS.TOSTORELOC IS NULL "

    + " THEN case WHEN MXZINVTRANS.TRANSTYPE_DESCRIPTION='Izdaja' "
        + " THEN case WHEN MXZINVTRANS.DOCUMENT LIKE '%-%' "
            + " THEN left(MXZINVTRANS.DOCUMENT, LOCATE('-',MXZINVTRANS.DOCUMENT)-1) "
            + " ELSE MXZINVTRANS.DOCUMENT "
        + " END "
    + " END "
    
+ " ELSE "
+ " MXZINVTRANS.TOSTORELOC "
+ " END "
+ " AS TOSTORELOC"

如果我使用红色圆圈中的代码而没有蓝色圆圈中的代码也可以。

+ " case " 
+ " WHEN MXZINVTRANS.TOSTORELOC IS NULL "
    + " THEN case WHEN MXZINVTRANS.TRANSTYPE_DESCRIPTION='Ident prejema' "
        + " THEN (select distinct VENDOR from PO where PO.PONUM=MXZINVTRANS.DOCUMENT) "
    + " END "
    
+ " ELSE "
+ " MXZINVTRANS.TOSTORELOC "
+ " END "
+ " AS TOSTORELOC"

有什么建议为什么不一起工作？

我在 SQuirrel 中尝试过，但我不明白为什么会出现这种语法错误？

这不起作用：

+ " (case WHEN MXZINVTRANS.TOSTORELOC IS NULL "


    + " THEN case WHEN MXZINVTRANS.TRANSTYPE_DESCRIPTION='Ident prejema' "
        + " THEN (select distinct VENDOR from PO where PO.PONUM=MXZINVTRANS.DOCUMENT) "
    + " END "
    
    + " THEN case WHEN MXZINVTRANS.TRANSTYPE_DESCRIPTION='Ident vračila' "
        + " THEN (select distinct VENDOR from PO where PO.PONUM=MXZINVTRANS.DOCUMENT) "
    + " END "
    
    
+ " ELSE "
+ " MXZINVTRANS.TOSTORELOC "
+ " END) "
+ " AS TOSTORELOC"

这是有效的：

+ " (case WHEN MXZINVTRANS.TOSTORELOC IS NULL "


    + " THEN case WHEN MXZINVTRANS.TRANSTYPE_DESCRIPTION='Ident prejema' OR MXZINVTRANS.TRANSTYPE_DESCRIPTION='Ident vračila' "
        + " THEN (select distinct VENDOR from PO where PO.PONUM=MXZINVTRANS.DOCUMENT) "
    + " END "
    
    
+ " ELSE "
+ " MXZINVTRANS.TOSTORELOC "
+ " END) "
+ " AS TOSTORELOC"
