BIRT 设计器在 CASE THEN 中选择语句

如何解决BIRT 设计器在 CASE THEN 中选择语句

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.MAXIMOQUANTITY,MXZINVTRANS.UNITCOST,MXZINVTRANS.LINECOST,MXZINVTRANS.FINPER,MXZINVTRANS.CURBALBEFORE,"
+ "         MXZINVTRANS.CURBALAFTER,MXZINVTRANS.COSTCENTER,MXZINVTRANS.COSTCENTER2,MXZINVTRANS.SAPUNITCOST,MXZINVTRANS.SAPPRICEUNIT,"
+ "         MXZINVTRANS.SAPLINECOST,MXZINVTRANS.SAPTRANSID,"
//+ "            (case MXZINVTRANS.TRANSTYPE  "
//+ "              WHEN 'RECEIPT' THEN 'Prejem' "
//+ "              WHEN 'RETURN' THEN 'Vrač. na skl.' "
//+ "              WHEN 'ISSUE' THEN 'TOREK' "
//+ "              WHEN 'TRANSFER' THEN 'Izd. med skl.' "
//+ "              WHEN 'INSERTITEM' THEN 'Insertitem_??' "
//+ "              WHEN 'VOIDRECEIPT' THEN 'Voidreceipt_??' "

//+ "              WHEN 'SHIPCANCEL' THEN 'shipcancel_??' "
//+ "              WHEN 'SHIPRECEIPT' THEN 'shipreceipts_??' "
//+ "           end) as tip_trans,"
+ "          (case MXZINVTRANS.TRANSTYPE_DESCRIPTION  "

+ "             WHEN 'Prenos pošiljke'  THEN (select description from locations where locations.location=MXZINVTRANS.tostoreloc and locations.siteid=MXZINVTRANS.SITEID) "
+ "             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,MXZINVTRANS.REFDOC)-1) and PO.SITEID=MXZINVTRANS.SITEID)) "
+ "             end) as opis_storeloc  "
//+ " (select description from locations where locations.location=MXZINVTRANS.tostoreloc and locations.siteid=MXZINVTRANS.SITEID) as opis_storeloc "

+ " FROM MXZINVTRANS "
// Include the Maximo where clause
//+ " where " + params["where"]

//+ " 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
+ blagskupinawhere
+ itemwhere
+ tipwhere


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

maximoDataSet.setQuery(sqlText);

这里可能是主要问题:

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

首先解释一下,REFODC 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,然后我将 VENDOR 打印为数字 114263,例如.

问题就在这里,我在这里有错误,但是如果我直接写 MXZINVTRANS.REFDOC number 4500038258 则没有错误。另外,如果只打印 REFDOC 值的这个子字符串,我会在报告时得到正确的子字符串并且没有错误,所以问题可能出在这里?

解决方法

假设您已经转储了生成的 SQL 语句并在 BIRT 之外成功测试了它,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,如果你的数据集有两个数据集参数,你需要正好两个绑定变量(语法是依赖于数据库的,JDBC标准?应该为每个数据库工作。

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"

当我像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红色圆圈中的代码有效时。

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

    + " THEN case WHEN MXZINVTRANS.TRANSTYPE_DESCRIPTION='Izdaja' "
        + " THEN case WHEN MXZINVTRANS.DOCUMENT LIKE '%-%' "
            + " THEN left(MXZINVTRANS.DOCUMENT,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蓝色圆圈中的代码也可以工作。

+ " 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吗?

,

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"
