Apache::DBI::Cache::myUser3Contributed Perl DocumeApache::DBI::Cache::mysql(3)NAMEApache::DBI::Cache::mysql - a Apache::DBI::Cache plugin
SYNOPSIS
use Apache::DBI::Cache plugin=>'Apache::DBI::Cache::mysql',
...;
or
use Apache::DBI::Cache;
use Apache::DBI::Cache::mysql;
DESCRIPTION
NOTE: Read Apache::DBI::Cache before.
"DBD::mysql" allows many different DSN syntaxes for connecting to the
same database server and the same database. This plugin transforms them
to a standard format thus allowing better DBI handle caching. Further,
if "port" is omitted the standard port 3306 is inserted. The actual
database is deleted from the DSN and replaced by a "USE database"
command.
So, DBI connects to the following DSNs as the same user at different
times are actually performed with the same DSN "host=server;port=3306".
Subsequently "USE db[1-3]" commands are issued before passing the
handle to the caller.
dbi:mysql:dbname=db1;host=server
dbi:mysql:db2:server:3306
dbi:mysql:port=3306;database=db3;host=server
Apache::DBI::Cache can cache them all under the same key. So only one
real database connection is needed instead of 3 without the plugin.
Furthermore, "mysql_auto_reconnect" is turned off.
