maxdb_info -- maxdb->info — Retrieves information about the most recently executed query
Procedural style
Object oriented style
The maxdb_info() function returns a string providing information about the last query executed. The nature of this string is provided below:
| Query type | Example result string |
|---|---|
| INSERT INTO...SELECT... | Records: 100 Duplicates: 0 Warnings: 0 |
| INSERT INTO...VALUES (...),(...),(...) | Records: 3 Duplicates: 0 Warnings: 0 |
| LOAD DATA INFILE ... | Records: 1 Deleted: 0 Skipped: 0 Warnings: 0 |
| ALTER TABLE ... | Records: 3 Duplicates: 0 Warnings: 0 |
| UPDATE ... | Rows matched: 40 Changed: 40 Warnings: 0 |
Note: Queries which do not fall into one of the above formats are not supported. In these situations, maxdb_info() will return an empty string.
A character string representing additional information about the most recently executed query.
Example #1 Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$maxdb->query("CREATE TABLE temp.t1 LIKE hotel.city");
/* INSERT INTO .. SELECT */
$maxdb->query("INSERT INTO temp.t1 SELECT * FROM hotel.city");
printf("%s\n", $maxdb->info);
/* close connection */
$maxdb->close();
?>
Example #2 Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
maxdb_query($link, "CREATE TABLE temp.t1 LIKE hotel.city");
/* INSERT INTO .. SELECT */
maxdb_query($link, "INSERT INTO temp.t1 SELECT * FROM hotel.city");
printf("%s\n", maxdb_info($link));
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Records: 25 Duplicates: 0 Warnings: 0
