Question

我有一个查询，我在Informix数据库上通过ODBC执行。查询正在传递参数（StartDate）。我需要多次使用StartDate的年份从正确的字段中获取数据。当我使用下面列出的查询时，它认为有9个参数。因此，我知道这种语法不正确，但是，我无法找到正确的语法。所以......

如何在Informix查询中多次引用相同的参数？

SELECT glma_segx AS AccountNumber, 
        glma_obj As AccountObject,
        glma_accttp AS AccountType,
        glma_desc AS AccountName,
        glma_seg1 AS AccountSeg1,
        glma_seg2 AS AccountSeg2,
        glma_seg3 AS AccountSeg3,
        glma_seg4 AS AccountSeg4,
        glma_seg5 AS AccountSeg5,
        glma_seg6 AS AccountSeg6,
        glma_seg7 AS AccountSeg7,
        glma_seg8 AS AccountSeg8,
        YEAR(?) AS BudgetYear,
   CASE WHEN YEAR(?) = glma_bud_yr THEN glma_memo_bal_cy 
        WHEN YEAR(?) = glma_bud_yr - 1 THEN glma_memo_bal_ly1
        WHEN YEAR(?) = glma_bud_yr + 1 THEN glma_memo_bal_ny
        ELSE 0
   END  AS YTDActuals,
   CASE WHEN YEAR(?) = glma_bud_yr THEN glma_encumb_cy 
        WHEN YEAR(?) = glma_bud_yr - 1 THEN glma_encumb_ly1
        WHEN YEAR(?) = glma_bud_yr + 1 THEN glma_encumb_ny
        ELSE 0
   END  AS YTDEncumbrances,
   CASE WHEN YEAR(?) = glma_bud_yr THEN glma_req_cy 
        WHEN YEAR(?) = glma_bud_yr + 1 THEN glma_req_ny
        ELSE 0
   END  AS YTDRequisitions
   FROM GLMaster, glparams 
   WHERE glma_seg1 NOT LIKE 'H%' 
   AND  glmaster.glma_bud_yr=glparams.glpa_curr_yr

提前感谢您提供的任何时间和帮助。

您必须提供参数的次数;如果有9个占位符，则需要提供9个值，如果它是9个相同的值，那就这样吧。
