BREAK statement in PL/pgSQL

Question

How to have the break statement in PostgreSQL? I have the structure like this:

for()
 {
 for()
 {
  if(somecondition)
  break;
 }
}

As per my understanding it should only break the inner for loop?

Answer 1

There is no BREAK in PL/pgSQL .

EXIT terminates the loop.
CONTINUE continues at the next iteration of the loop.
You can attach a <<label>> to loops and add it as parameter to each of these commands. Then you terminate / continue the labeled loop. Else, it concerns the inner loop.
RETURN exits from the function (so not applicable in a DO statement).

All of this applies to procedural elements of PL/pgSQL, not SQL.
Code example using all three:

• Loop in function does not work as expected
