RE: SQL: how to filter out spaces in fields defined as packed numeric

[John King <jking@xxxxxxxxxxxxxxxxx>]

Joel,

 Had to repair some packed data the other day. It was a one-time task and the replacement values were always = '0' so the fix didn't need any particular logic. Testing for 'F' was sufficient.


Update mytable
Set badcolumn = 0
Where left(hex(badcolumn),1) <> 'F'
;

Joel,
Try this:
SELECT f1.f2.etc.  from Datafile where substr(OrderQty,1,1) = x'40'
Replace the f1,f2,etc with field names from the file, but not the OrderQty which SQL will see as invalid data.
