I can't get the LIKE expression to work using VDSDB.DLL version 2! The Date Query works fine, but both the Postcode & Quote Query do not work!

Am I getting the syntax wrong?

There is a segment of code below, which is used to populate an EXTLIST:-

Code:

  %%ENDIF = ListBegin
  IF @EQUAL(%K,Date)
    %%Query = "SELECT QuoteNo, RDate, Business, BusType, PostCode, BuildSI, ContSI, StockSI, Gross, IPT, Net, OnCoverYN FROM NU WHERE (((QDate) Between #"%%Date1"# And #"%%Date2"#));"
  END   
  IF @EQUAL(%K,Postcode)
    %%Query = "SELECT QuoteNo, RDate, Business, BusType, PostCode, BuildSI, ContSI, StockSI, Gross, IPT, Net, OnCoverYN FROM NU WHERE ([Postcode]) LIKE '"%J"*';"
  END   
  IF @EQUAL(%K,Quote)
    %%Query = "SELECT QuoteNo, RDate, Business, BusType, PostCode, BuildSI, ContSI, StockSI, Gross, IPT, Net, OnCoverYN FROM NU WHERE ([QuoteNo]) LIKE '"%J"*';"
  END
 
  %Z = @INPUT(Query,%%Query)
 
  EXTLIST ADD,COLLIST,COLLIST1,1,1,798,598,QuoteNo|60@CR()Renewal Date|80@CR()Business|150@CR()BusinessType|80@CR()PostCode|80@CR()BuildingsSI|80@CR()ContentsSI|80@CR()StockSI|80@CR()Gross|80@CR()IPT|80@CR()Net|80@CR()OnCoverYN|60,DBLCLICK,COLUMNCLICK
  DB QUERY,%%Query
  DB FETCHROW
  IF @OK()
    %A = 1
    REPEAT
     %%Query = @DB(GET,QuoteNo)@TAB()@DB(GET,RDate)@TAB()@DB(GET,Business)@TAB()@DB(GET,BusType)@TAB()@DB(GET,PostCode)@TAB()@FORMAT(@DB(GET,BuildSI),5.2)@TAB()@FORMAT(@DB(GET,ContSI),5.2)@TAB()@FORMAT(@DB(GET,StockSI),5.2)@TAB()@FORMAT(@DB(GET,Gross),5.2)@TAB()@FORMAT(@DB(GET,IPT),5.2)@TAB()@FORMAT(@DB(GET,Net),5.2)@TAB()@DB(Get,OnCoverYN)
     EXTLIST LIST,ADD,COLLIST1,%%Query
     %A = @SUCC(%A)
     DB FETCHROW
   UNTIL @NOT(@OK())@EQUAL(%A,100)
   IF @EQUAL(%A,100)
     INFO You have over 100 quotes in the requested data range!@CR()@CR()Try amending the selection criteria...
   END 
  ELSE
    IF @ASK(There are no retrieved records! Do you want to try again?)
     %%ENDIF = GetButton
   ELSE
     %%ENDIF = EvLoop
      EXTLIST REMOVE,COLLIST1 
      DIALOG HIDE,LISTSGROUP
   END 
  END
  GOTO %%ENDIF


The %Z = @INPUT(Query,%%Query) produces an SQL string that works fine in Access97, Access2000 and Access2003, but not using VDSDB.DLL

Thanks in advance

I have replaced the LIKE with >= which does work!

Code:

   IF @EQUAL(%K,Postcode)
    %%Query = "SELECT QuoteNo, RDate, Business, BusType, PostCode, BuildSI, ContSI, StockSI, Gross, IPT, Net, OnCoverYN FROM NU WHERE Postcode >= '"%J"';"
  END   


So I am sorted now thanks!




Andy
