ibec_SetGlobalVar

ibec_SetGlobalVar allows you to create/modify a global variable. This function always returns 0.

 function ibec_SetGlobarVar(VarName : string; VarValue : variant):variant;

If you're using the ibec_SetGlobalVar function within scripts executed with IBEScript, it is not necessary to free global variables - they will be destroyed automatically after the script has finished.

If you're using the ibec_SetGlobalVar function within IBExpert (SQL Editor or the Script Executive), any global variables created will continue to exist until you close IBExpert. So if necessary, you should free them manually using the ibec_FreeGlobalVar function.

The following example illustrates the use of this function, together with ibec_GetGlobalVar, described within an SQL script:

   CONNECT ...;
 
   execute ibeblock
   as
   begin
     select myfield from mytable
     where something = 25
     into :MyVar;
     ibec_SetGlobalVar('MyGlobalVar', MyVar);
   end;
 
   ...
 
   execute ibeblock
   as
   begin
     MyVar = ibec_GetGlobalVar('MyGlobalVar', null);
     if (MyVar = 1) then
       insert into mytable ...;
     else if (MyVar = 2) then
       update mytable set ...;
   end;
