Subject: [SQL] Invalid syntax for integer
hi ,
what is wrong with this if statement in this function
if distance ='' THEN
distance := 1;
end if;
here distance variable is of type integer , this function has been created
successfully but when i execute this function it gives me this error ,
ERROR: invalid input syntax for integer: ""
LINE 1: SELECT distance =''
^
QUERY: SELECT distance =''
CONTEXT: PL/pgSQL function "getsitesbytfid" line 6 at IF
********** Error **********
ERROR: invalid input syntax for integer: ""
SQL state: 22P02
Context: PL/pgSQL function "getsitesbytfid" line 6 at IF
========================================================================
The empty-string is not a valid syntax for an integer.
You probably want: IF (distance IS NULL) .
