my_ulonglong mysql_stmt_affected_rows(MYSQL_STMT *stmt)
Description
Returns the total number of rows changed, deleted, or inserted by the last
executed statement. May be called immediatlely after mysql_execute()
for UPDATE, DELETE, or INSERT statements. For
SELECT statements, mysql_stmt_affected() rows works like
mysql_num_rows().
Return Values
An integer greater than zero indicates the number of rows affected
or retrieved. Zero indicates that no records were updated for an
UPDATE statement, no rows matched the WHERE clause in
the query, or that no query has yet been executed. -1 indicates that
the query returned an error or that, for a SELECT query,
mysql_stmt_affected_rows() was called prior to calling
mysql_fetch().
Errors
None.
Example
For the usage of mysql_stmt_affected_rows(), refer to the Example
from section 9.1.7.5 mysql_execute().
