Daniel,

I still get the same result. Is there something I'm missing? I copied your code exactly and still get the same result set.

Thanks for your assistance.

>>>Assuming that your backend is SQL Server, the following should work:
>>>
>>>lcList = ['1','2','3','4']
>>>lcCmd  = 'select cname from customers where CHARINDEX(RTRIM(CAST(icustomerid as char(20))), ?lcList)>0'
>>>? sqlexec(lnHandle,lcCmd)

>>>It's a bit of a hack, but it works :-)
>>>The CHARINDEX() function is similar to VFP's AT() function and returns the starting position of the specified expression in a character string.
