Create function question...

Ok, my syntax is off somewhere. Can someone set me straight on how to declare a local variable in a function?

Expand|Select|Wrap|Line Numbers
  1. CREATE OR REPLACE FUNCTION BLAH( bigint )
  2.  declare int cnt
  3. RETURNS void as
  4. $$
  5.     cnt = select count(*) from "DCx" where "Index" = $1;
  6.     if cnt > 0
  7.     then
  8.         -- do something
  9.     end if
  10.  
  11. $$
  12. LANGUAGE sql;
  13.  
The error I get is the following...
ERROR: syntax error at or near "declare"

Looks like the variable declaration is misplaced (among other problems)...

Just take a look at the manual.
create function
sql function
plpgsql
Declarations in plpgsql functions

Let us know if you still have any questions or problems with your code.

I have a Class Library that contains a Form and several helper classes. A thread gets created that performs processing of data behind the scenes and the Form never gets displayed (it is for debug puposes only and is not normally visable to the user.) The Thread function is actually in the Form class. Now.. What I am seeing is that when I create an instance of this Class Library's Form, which starts the worker thread, it seems to hose up...

I am a postgres newbie. I am trying to create a trigger that will put a copy of a record into a backup table before update or delete. As I understand it, in order to do this I must have a function created to do this task.

In this case, I am trying to do additional permissions enforcement. I have written a function to do the checking, but when I create the rule, I get an error. So here...

I've seen plenty of articles on this topic but none of them have been able to solve my problem. I am working with an Access 97 database on an NT4.0 machine, which has many Access reports. I want my users to be able to select a report, click on a command button on a form, which will then automatically create the report as a pdf file and save it to the user's machine.

I am trying to create multi-dimensioned arrays in conventional ASP pages and pass these arrays as arguments to functions that are in a C# interop assembly.

Just noticed this for the first time: http://us2.php.net/manual/en/function.create-function.php Anyone know if PHP supports enclosures, like Javascript or Ruby? I've always assumed PHP lacked these. If I create a function with object instances, will the instances retain their state if the function definition is stored in a variable?
