MAXDB_INSERT_ID(3) 1 MAXDB_INSERT_ID(3) maxdb_insert_id - Returns the auto generated id used in the last query Procedural style SYNOPSIS
mixed maxdb_insert_id (resource $link) DESCRIPTION
Object oriented style mixed$maxdb->insert_id () The maxdb_insert_id(3) function returns the ID generated by a query on a table with a column having the DEFAULT SERIAL attribute. If the last query wasn't an INSERT or UPDATE statement or if the modified table does not have a column with the DEFAULT SERIAL attribute, this function will return zero. RETURN VALUES
The value of the DEFAULT SERIAL field that was updated by the previous query. Returns zero if there was no previous query on the connec- tion or if the query did not update an DEFAULT_SERIAL value. Note If the number is greater than maximal int value, maxdb_insert_id(3) will return a string. EXAMPLES
Example #1 Object oriented style <?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } maxdb_report (MAXDB_REPORT_OFF); $maxdb->query("DROP TABLE mycity"); maxdb_report (MAXDB_REPORT_ERROR); $maxdb->query("CREATE TABLE mycity LIKE hotel.city"); $maxdb->query("ALTER TABLE mycity ADD id FIXED(11) DEFAULT SERIAL"); $query = "INSERT INTO mycity (zip,name,state) VALUES ('12203','Albany' ,'NY')"; $maxdb->query($query); printf ("New Record has id %d. ", $maxdb->insert_id); /* drop table */ $maxdb->query("DROP TABLE mycity"); /* close connection */ $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } maxdb_report (MAXDB_REPORT_OFF); maxdb_query($link,"DROP TABLE mycity"); maxdb_report (MAXDB_REPORT_ERROR); maxdb_query($link, "CREATE TABLE mycity LIKE hotel.city"); maxdb_query($link, "ALTER TABLE mycity ADD id FIXED(11) DEFAULT SERIAL"); $query = "INSERT INTO mycity (zip,name,state) VALUES ('12203','Albany' ,'NY')"; maxdb_query($link, $query); printf ("New Record has id %d. ", maxdb_insert_id($link)); /* drop table */ maxdb_query($link, "DROP TABLE mycity"); /* close connection */ maxdb_close($link); ?> The above example will output something similar to: New Record has id 1.

MAXDB_AFFECTED_ROWS(3) 1 MAXDB_AFFECTED_ROWS(3) maxdb_affected_rows - Gets the number of affected rows in a previous MaxDB operation Procedural style SYNOPSIS
int maxdb_affected_rows (resource $link) DESCRIPTION
Object oriented style int$maxdb->affected_rows () maxdb_affected_rows(3) returns the number of rows affected by the last INSERT, UPDATE, or DELETE query associated with the provided $link parameter. If this number cannot be determined, this function will return -1. Note For SELECT statements maxdb_affected_rows(3) works like maxdb_num_rows(3). The maxdb_affected_rows(3) function only works with queries which modify a table. In order to return the number of rows from a SELECT query, use the maxdb_num_rows(3) function instead. RETURN VALUES
An integer greater than zero indicates the number of rows affected or retrieved. Zero indicates that no records where 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 number of rows affected can not be determined. EXAMPLES
Example #1 Object oriented style <?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } maxdb_report (MAXDB_REPORT_OFF); $maxdb->query("DROP TABLE mycustomer"); maxdb_report (MAXDB_REPORT_ERROR); /* Insert rows */ $maxdb->query("CREATE TABLE mycustomer AS SELECT * from hotel.customer"); printf("Affected rows (INSERT): %d ", $maxdb->affected_rows); $maxdb->query("ALTER TABLE mycustomer ADD Status int default 0"); /* update rows */ $maxdb->query("UPDATE mycustomer SET Status=1 WHERE cno > 50"); printf("Affected rows (UPDATE): %d ", $maxdb->affected_rows); /* delete rows */ $maxdb->query("DELETE FROM mycustomer WHERE cno < 50"); printf("Affected rows (DELETE): %d ", $maxdb->affected_rows); /* select all rows */ $result = $maxdb->query("SELECT title FROM mycustomer"); printf("Affected rows (SELECT): %d ", $maxdb->affected_rows); $result->close(); /* Delete table Language */ $maxdb->query("DROP TABLE mycustomer"); /* close connection */ $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); if (!$link) { printf("Can't connect to localhost. Error: %s ", maxdb_connect_error()); exit(); } maxdb_report (MAXDB_REPORT_OFF); maxdb_query($link,"DROP TABLE mycustomer"); maxdb_report (MAXDB_REPORT_ERROR); /* Insert rows */ maxdb_query($link, "CREATE TABLE mycustomer AS SELECT * from hotel.customer"); printf("Affected rows (INSERT): %d ", maxdb_affected_rows($link)); maxdb_query($link, "ALTER TABLE mycustomer ADD Status int default 0"); /* update rows */ maxdb_query($link, "UPDATE mycustomer SET Status=1 WHERE cno > 50"); printf("Affected rows (UPDATE): %d ", maxdb_affected_rows($link)); /* delete rows */ maxdb_query($link, "DELETE FROM mycustomer WHERE cno < 50"); printf("Affected rows (DELETE): %d ", maxdb_affected_rows($link)); /* select all rows */ $result = maxdb_query($link, "SELECT title FROM mycustomer"); printf("Affected rows (SELECT): %d ", maxdb_affected_rows($link)); maxdb_free_result($result); /* Delete table Language */ maxdb_query($link, "DROP TABLE mycustomer"); /* close connection */ maxdb_close($link); ?> The above example will output something similar to: Affected rows (INSERT): 15 Affected rows (UPDATE): 15 Affected rows (DELETE): 0 Affected rows (SELECT): 15 SEE ALSO
