MSSQL TOP n equivalent for Informix?

MSSQL TOP n equivalent for Informix?

I'm working on an application which will work against several DBMS's. I've found that if I use the MSSQL specific TOP n in one of my queries I cut time to a third.

I've been looking for an equivalent that for INFORMIX.

Basically it returns either the TOP n percent, or the TOP n rows. I need something that returns only 1 row, as TOP 1 would do.

Is there a equivalent thing for INFORMIX?



RE: MSSQL TOP n equivalent for Informix?


Check the documentation on the informix select clause.  New, with the 7.x engine, you can do something like this:

selct FIRST 2 {+FIRST_ROWS} * from some_table
  where some_column = "some_value"

The above gets the first two rows.

select max(column_name)
