I got an error SQL1042C. An unexpected system error
occurred.
Explanation:
A system error occurred. One possible reason for this error
is that the database manager is not installed correctly or
the environment is not set up correctly.
On OS/2, while trying to start the database manager, a very
common reason for this error is a corrupted NET.ACC file.
The command cannot be processed.
The tables and views would not be opened. What is the way
to open the dataase?

My requirement is like in database some defects are present
and i need to clean them.To be brief for example every
employee should have active assigments.So for those records
which are not having status as active or null ,i need to
update the roecords using API with the correct value.
Client will provide a flat file for the records whch are
defected.So i need to run the API for those records (flat
file)and update the data in database.
So my question is how to handle this requirement.Is there
any existing API for this purpose?If yes then please send
me the NAME.
How to update the records in the database using flatfile.
Any pointer will be appreciated.Thanks in advance.
