Subject:how does one successfully use mysql_store_result()?
View as plain text  
If I understand you correctly, then you are trying to figure out how to
distinguish between an empty result set vs. no result set (i.e. an error if
statement was a SELECT).

In the case of an error (or a not result set returning statement like
INSERT), mysql_store_result will return null.

In the case of an empty set, it will return a (non-null) pointer to a set
that is empty.  Subsequent to this, mysql_fetch_row() will return a null
pointer indicating you have reached EOF for the result set.

Hope this helps

---- original message text ----
HOW does one use this to confirm a record set?  for instance,

if mysql_store_result() = 0 then
    do nothing
end if

where mysql_store_result() returns an empty set on a select statement.

any help obtained would be WONDERFUL!!!  sorry, i'm new to this, the
syntaxtual information is quite confusing to me.
