Is this a bug in 7.0.2?
Dear all,
I've migrated from RedHat6.2/PHP3.0/PostgreSQL6.5 to
Mandrake/PHP4.0/Postgres7.0.2 successfully as far as
pg_dump database_name is concerned.
I am still running BOTH versions on two computers.
PostgreSQL6.5 does not produce any error using math function "integer
(float_expression)"
(even "int(float_expression" is OK with 6.5)
and 7.0.2 complains saying:
"function integer(float8) is not found for specified types"
The query is used in something like this:
SELECT
attr-1,
attr-2,
...
attr-k,
integer(attr-2 * $php_variable_1 + atrr-3 * $php_variable_2) AS attr-N
FROM
table_1, table_2
WHERE
clause_1 AND
clause_2
ORDER BY
attr-2, attr-4
If I made an error HERE with the sintax, I apologise - I am not close to
my both Linux machines,
and sintax is OK in my real SELECT queries.
"$php_xxx"s are PHP variables and "attr-xxx"s are SQL table attributes.
The "integer(float_expression)"
is more complicated then written above BUT it all DOES work in 6.5 and
DOES NOT in 7.0.2.
Any ideas, please?
Much obliged,
Steven.

Try using int2()/int4()/int8() instead of integer(). The intn() functions
convert the float to a integer n bytes long, in normal cases you probably
want to use int4().

Einar,
Much obliged.
int4() has done a job.
Why is that NOT documented under "Matematical functions"?
Regards,
Steven.
