Description
int
fbsql_affected_rows ( [resource link_identifier] )
fbsql_affected_rows() returns the number
of rows affected by the last INSERT, UPDATE or DELETE query
associated with link_identifier. If the
link identifier isn't specified, the last link opened by
fbsql_connect() is assumed.
Note:
If you are using transactions, you need to call
fbsql_affected_rows() after your INSERT,
UPDATE, or DELETE query, not after the commit.
If the last query was a DELETE query with no WHERE clause, all of
the records will have been deleted from the table but this
function will return zero.
Note:
When using UPDATE, FrontBase will not update columns where the
new value is the same as the old value. This creates the
possibility that fbsql_affected_rows() may not
actually equal the number of rows matched, only the number of
rows that were literally affected by the query.
If the last query failed, this function will return -1.
