Hi I am using PQgetvalue() function in  c to get the value of a field like
 
 PQgetvalue(result,0,2)
 
 but the program outputs following
 
"column number 2 is out of range 0..0"
 
 Can someone tell me how can I get this field and whats wrong?
 
 Thanks

Your result doesn't actually have three columns --- apparently it
has just one.  Better check which query you were issuing.
