检查 SQR 中的重复项

Checking for duplicates in SQR

我目前正在尝试更新 SQR 以检查给定记录中跨列的重复值。我们允许在 table 中输入重复项,但我们希望在它中断下一个程序时检查错误标志。

ID - 1 Var1 - 3809 Var2 - 3809
ID - 2 Var1 - NULL Var2 - NULL
ID - 3 Var1 - 5204 Var2 - 3809

在这种情况下,ID 1 会检查错误标志,而其他两个则不会。我不能简单地检查值,因为我需要检查 12 个不同的列。任何帮助将不胜感激。

谢谢! 旦

我试过下面的代码,可以编译,但不记录重复项

begin-procedure check-duplicates

          Get $Val1 from SchlDuplicates(#I) Val
          Get $Val2 from SchlDuplicates(#J) Val
          If $Val1 = $Val2
     let $DupFound = 'Y'

end-procedure

这将使用您的代码并为每个具有重复项的记录调用插入错误例程。这会用 dups 标记每条记录(但每条记录只有一个)。如果您只希望所有记录出现一处错误,请告诉我。
