Server Session Management
A DataBlade client application manages sessions by establishing one or more connections to the database server before it can access data. However, a DataBlade server routine performs session management differently because it is called within the context of an SQL statement. Therefore, the server routine is already connected in a particular database server and has access to a database that has already been opened. The server routine is also inside the current transaction.
User-defined routines that require a connection must first perform
mi_open()
to set up the default server connection information.
Warning:
Do not pass connections as arguments to other server user-defined routines either directly or as part of an
FPARAM
value.
Unpredictable behavior might result.
