Re: [U2] [UV] QSELECT in transaction
Assuming we're talking about uniVerse (and not uniData): PERFORM is a different command. EXECUTE creates it's own execution environment, where PERFORM does not. This means that with PERFORM you can do a series of SELECT statements in the following way: PERFORM SELECT ANIMAL WITH SPECIES = 'Lion' IF (@SYSTEM.RETURN.CODE 0) THEN PERFORM SELECT ANIMAL WITH NAME = 'Simba' END At the end of this BASIC code your active select list contains all records matching the select statements as if you entered them on the command line. With an EXECUTE this does not work. To achieve the same result with an EXECUTE you'd have to do the following: EXECUTE SELECT ANIMAL WITH SPECIES = 'Lion' AND NAME = 'Simba' SETTING nrOfRecords Depending on your selection you'd have to chose what is best. If you're using complicated I-descriptors (that can make selecting on them slow), I'd use a series of PERFORM statements instead of an EXECUTE. If you're using @USER0 through @USER4 in your I-descriptors, those won't be propagated to the statements you run with an EXECUTE statement so you'd have to use a (series of) PERFORM statements for those. As for the original question in this thread, I'm afraid you can't use a QSELECT inside a transaction on uniVerse. I'd like to add that doing SELECT / SSELECT statements inside database transactions on uniVerse can sometimes cause database corruption (we once had this happen to one of our customers' accounts), so I would advise against that.

RE: [U2] Replication Between Unidata and MySQL
Kevin I'd go for a 'keep it simple' approach. First, create three data files on UniData: SYNC_TARGETS, SYNC_ACTIONS and SYNC_ERRORS. - The SYNC_TARGETS defines a table or entity to update, including insert and delete commands (Update=delete+insert) and a list of column positions to substitute. This may seem overkill but it allows you to format the SQL the way you want, and possibly specify stored procedures (AFAIK MySQL 5 has stored procedures but I haven't used them yet) - The SYNC_ACTIONS holds the actions, each specifying a target, action type (update,insert,delete) and a list of fields that match the column positions specified in the target. - The SYNC_ERRORS logs errors. How you populate the action is then up to you: using triggers, virtual secondary index fields or whatever... Then, write a simple VB/Delphi/.NET/VBScript app with a UO connection to: - load up the targets for reference - select the actions (on a timer loop) sorted by target (so you get advantages of query preparation and caching - it is worth not making the timer interval too short) - prepare insert and delete ADODB commands on each change of target - substitute the parameters and fire the delete and/or insert commands as required It means having a Windows box in the middle, but the route is well known. Any failure just means the actions accumulate until drained. I have a working example I can dig out and send you.

[U2] [UV] exit status and @SYSTEM.RETURN.CODE
I am calling a UniVerse BASIC program TEST from the UNIX command prompt using the following command 'uv TEST' which sets @SYSTEM.RETURN.CODE to various values. I was hoping to be able to check the exit status of the uv command thinking that @SYSTEM.RETURN.CODE may be used to set the exit status, but it appears that is not the case. Is this expected behaviour, or is there a way of doing this, apart from displaying the value of @SYSTEM.RETURN.CODE and capturing the output.

[U2] [UV] QSELECT in transaction
Whats slightly confusing / inconsistent is that an EXECUTE with SELECT / SSELECT is catered for inside a transaction but not QSELECT? Why allow / cater for one and not the other? -Brian.

Rich, One important issue to know is to determine if you need a 64 or 32 bit UNIX driver. Also what is your .udlibs soft link look like? Hope this helps.
