Re: sql DELETE FROM with wildcard "%"

Hi Joe,

The following example with Trim and Concats also works:
C                   Eval      HstNameFix = 'Media'

C/Exec SQL
C+ Delete from MyTable
C+            Where Name like '%' concat Trim(:HstNameFix) concat '%'
C/END-EXEC

Mit freunlichen Grüßen / Best regards

Thanks, Birgitta... I hadn't tried a varying field. It's good to know that

it works the way one would expect.

It's also nice to know that you can use TRIM on a host variable.  It would
be nice if you could then concatenate that trimmed variables with a '%'
right in the SQL statement.

Hi,

there are several possibilites to solve your problem:

Here are some examples:
D HstName         S             50A   varying
D HstNameFix      S             50A
 *------------------------------------------------------
C                   Eval      HstNameFix = '%Media%'

C/Exec SQL
C+ Delete from MyTable
C+            Where  Name Like Trim(:HstNameFix)
C/End-Exec

C                   Eval      HstName = '%Meier%'

C/Exec SQL
C+ Delete From MyTable
C+            Where Name Like :HstName
C/End-Exec

C                   Eval      HstName = 'Miller'

C/Exec SQL
C+ Delete From MyTable
C+            Where PosStr(Name, :HstName) > 0
C/END-EXEC

C                   Eval      HstNameFix = 'Brown'

C/Exec SQL
C+ Delete From MyTable
C+            Where PosStr(Name, Trim(:HstNameFix)) > 0
C/END-EXEC

Hope this helps.

Mit freunlichen Gruessen / Best regards
