AW: Using the LIKE feature within a SELECT in Embedded SQL for RPG

["HauserSSS" <Hauser@xxxxxxxxxxxxxxx>]

Hi,

you either have to use a varying length field containing the like value,
or use the sQL scalar function to trim off trailing blanks:

Example:
D HstName         S             50A   varying       
D HstNameFix      S             50A                 
D DspName         S             50A                 
 *------------------------------------------------------------
C                   Eval      HstNameFix = '%CANADIAN%'       
                                                           
C/Exec SQL                                                 
C+ Declare CsrC0 Cursor for                                
C+   Select Name1F from Adresse                            
C+            Where     Name1F Like Trim(:HstNameFix)      
C/End-Exec                                                 
                                                           
c/EXEC SQL Open CsrC0                                      
C/END-EXEC

Betreff: Using the LIKE feature within a SELECT in Embedded SQL for RPG


    I am tring to use the LIKE function within my SELECT statement, and am 
having some 
    trouble with it.
    Both my prompt field and field I want to search are 30a.
    Ex:  I key "CANADIAN" on the prompt and want to return to my subfile 
any 
    records with "CANADIAN COAST GUARD" and "MOLSON CANADIAN" and "THE 
    CANADIANS WIN HOCKEY GOLD AGAIN".
    c/exec sql 

    c+ declare maincursor cursor for select * from wmmstr where 
    c+ :pname like wmname order by wmname 
    c/end-exec 
 
    Thanks,
    Pat.
