>>>Hi,
>>>
>>>Say I am executing the SQL Update from a VFP PRG file, against a SQL Server. This is the syntax:
>>>
>>>cSqlUpdate = "update MyTable set Field1 = '12345' where Field2 = 'XYZ'"
>>>nResult = SQLEXEC(hCon, cSqlUpdate)	
>>>
>>>
>>>How do I determine, in my PRG code, that a record has been updated? That is, without searching for the Field2 = 'XYZ'.
>>>
>>>TIA
>>
>>Check nResult which gives the number of records that are updated.
>
>It does not do it in my case. What I found working is adding parameter aCountInfo to the SQLEXE(). VFP populates this array with the number of records updated.
