Do you have primary key defined on your table ? (it seems, that yes)
YES, totally 2 fields in DB where 1 st is primary key,
I paid much attention when creating that table in MS managment studio, "Allow Nulls" to be unchecked in order to overcome that issue. But stil the same.
Updatemode = UpWhereKeyOnly
ParseSQL = True
UsePrimaryKeyAsKey = true
I simply use SQLQuery.SQL := ' select * from Table1'
Can you insert new records ? (or problem exists only when updating existing record)
Actually the scenario is a bit different for me here, either inserting or trying to change the existing records compiler throws exception with "Parapemeter 0 is of type WideString, which not supported yet"
Do you insert null values in some columns ?
NO,
But need to inform you about one weird thing, Even though I was deliberetly careful not use null values in records when I open the table in MS managment studio the last row is always filled with null values.
Thanks in advance,
