Databases Reference
In-Depth Information
We see (in the reverse order) the last successful queries and the database on which
they were made. Queries typed only from the query box are kept in this history,
along with queries generated by phpMyAdmin (such as those generated by clicking
on Browse ).
They are clickable for immediate execution, and the Change icon is available to insert
a recorded query into the query box for editing.
The number of queries that will be kept is controlled by $cfg['QueryHistoryMax'] ,
which is set to 25 by default. This limit is not kept for performance reasons, but as
a practical limit in order to achieve a visually unencumbered view. Extra queries
are eliminated at login time in a process traditionally called garbage collection . The
queries are stored in the table configured in $cfg['Servers'][$i]['history'] .
Editing queries
On the results page of a successful query, a header containing the executed query
appears as shown in the following screenshot:
