Thread: error code invalid_input_syntax

I wrote a function which generates SQL statements
for INSERTs and UPDATEs, in which I cast the values
to the correct datatype.

Now I want to catch

ERROR:  invalid input syntax for integer: "i"

but although I tried quite a few I can't find the right
error code for this exception.

Is it possible that this error can not be caught?


Thanks
Leo

Crank up the error reporting verbosity.  For instance, in psql

regression=# select 'i'::integer;
ERROR:  invalid input syntax for integer: "i"
regression=# \set VERBOSITY verbose
regression=# select 'i'::integer;
ERROR:  22P02: invalid input syntax for integer: "i"
LOCATION:  pg_atoi, numutils.c:84
regression=#

A look in Appendix A of the manual shows that 22P02 is
INVALID TEXT REPRESENTATION
