Select query in visual basic 6

Hi guys,

I'm a newbie to this forum and to vb6.I just want to ask some help for my query.

I have a table prodmaster with fields pieceCode,dozenCode,caseCode, proddesc ,inventoryUnit.
example: pieceCode | dozenCode | caseCode | proddesc | inventoryUnit
110 111 112 Apple 72

note: inventory unit is constant and all code refers to one item only
I also have a flexgrid and a txtinvno.text

If I put invoice number in the textbox say inv#00152
My flexgrid displays all the products issued in that invoice (inv#00152) and those products may be served in dozen,in piece or in case.


what I want to do now is if my flexgrid(2,1)=rs!pieceCode or flexgrid(2,1)=rs!dozenCode or flexgrid(2,1)=rs!caseCode then flexgrid(2,2)=flexgrid(2,2)/rs!inventoryUnit.

the value of flexgrid(2,1) piececode,dozencode,or casecode of the product issued since we serve some items in piece,dozen, or case.
the value of flexgrid(2,2) is the quantity issued.

.
can anybody out there help me? what should be my query for this.


I tried Select * from prodmaster where prodCode='"& flexgrid(2,1) &"' or dozenCode='"& flexgrid(2,1) &"' or caseCode='"& flexgrid(2,1) &"' ,

I know it can't be done this way,

help please.
