Introduction to SPL Routines
In Universal Server, SPL
routine
is a generic term that includes SPL
procedures
and SPL
functions
. An SPL
procedure
is a routine written in SPL and
SQL
that does not return a value.
An SPL
function
is a routine written in SPL and
SQL
that returns a single value, a value with a complex data type, or multiple values. Any routine written in SPL that returns a value is an SPL function.
Tip:
Many of the routines that you wrote in SPL
in earlier Informix products are now called
SPL
functions.
