Store Procedure and View Creation
by DevX Pro
We need to create a view based on about 1600 tables. One of the problems is that we cannot enter all of the query into the buffer because the query takes too much space (more than 32k). Can we create a view by calling some store procedure? If so, can we use the same technique for the insert, update, and delete into that view?
Locking Rows
by DevX Pro
We are developing an intranet application using visual interdev on windows 2000 and our informix database is on unix. We are using stored procedures and the 'begin work' and 'commit' statements to update, insert and delete. We can lock the rows while in the stored procedure. However, we need to lock the row while the user is making changes on the intranet and not release it until the update statement has been committed.

I've archived/purged a few thousand rows of unnecessary data, but the disk space reading hasn't changed. Do I need to use the ALTER TABLE command to reclaim empty space from deleted rows?
Informix Data Types

Does Informix support user-defined data types?
by DevX Pro
When accessing dbaccess through a script (in UNIX), what is the importance of the hyphen after the database name? For example: dbaccess mystores- Why do we need a hyphen after mystores?
Error in Timed Job
by DevX Pro
I am getting an error ("Could not do a physical-order read to fetch next row" #244) while executing a job that runs a set of SQL statements every 30 minutes. When we stop the job and run it again after a few minutes, it runs fine. So I don't think it is a corrupted index file problem, as the book describes it. What else could cause this error?
Shared Memory Error
by DevX Pro
My Informix usually server starts fine, but when I try to add a database chunk with the onspaces command I get an error ("shared memory not initialized"). Any ideas?
Transaction State
by DevX Pro

ASP Error: ODBC Driver General Error
by DevX Pro
I have been receiving the following (albeit general) error sporadically: "Microsoft OLE DB Provider for ODBC Drivers error '80004005' [Informix][Informix ODBC Driver]General error." This error has occurred when the code accesses the datasource: (set conn = server.createobject ("ADODB.connection"): conn.open "DatasourceName". However, it happens only occasionally when using ASP. Cold Fusion does not yield the same type of error. Any suggestions?
Cursors in Informix
by DevX Pro
What is the purpose of using the fetch and declare cursor in Informix.4GL? How do you use the scroll cursor, and what are its advantages?
Date Time Values in Parameterized Queries
by DevX Pro
I have a parameterized SQL statement like the following: "insert into eSession (ESessionID, eUserName, eLastActivityTime) VALUES(?,?,?)" It's parameters are 'bbb','name' and '2000/01/01 22:23:25', using an ODBC connection. I can't make the date work. Even using the ODBC timestamp format of {ts'yyyy-dd-mm hh:nn:ss'} does no good, although it does work when the statement is not parameterized, like so: "insert into eSession (ESessionID, eUserName, eLastActivityTime) VALUES('bbb','name',{ts '2000-01-01 22:23:25'})" Is there a generic solution that works with SQL Server, Oracle and Access (I know, but I was young and needed the money)?
Releasing Database Locks

Database Connectivity
by DevX Pro
I am trying to connect to an Informix database via ODBC from Microsoft Access 2000. When I import a table from the Informix database, I see all the data. But why can't I open the datasheet to view the records when I link the table?
