Detailed Description

Database abstraction object for MySQL.

Defines methods independent on used MySQL extension.

Since: 1.22

See also: Database

Definition at line 32 of file DatabaseMysqlBase.php.

Constructor & Destructor Documentation

DatabaseMysqlBase::__construct ( array $params )

Additional $params include:

lagDetectionMethod : set to one of (Seconds_Behind_Master,pt-heartbeat). pt-heartbeat assumes the table is at heartbeat.heartbeat and uses UTC timestamps in the heartbeat.ts column. (https://www.percona.com/doc/percona-toolkit/2.2/pt-heartbeat.html)
lagDetectionOptions : if using pt-heartbeat, this can be set to an array map to change the default behavior. Normally, the heartbeat row with the server ID of this server's master will be used. Set the "conds" field to override the query conditions, e.g. ['shard' => 's1'].
Parameters

array $params

Definition at line 55 of file DatabaseMysqlBase.php.

Member Function Documentation

DatabaseMysqlBase::addIdentifierQuotes ( $s )

MySQL uses backticks for identifier quoting instead of the sql standard "double quotes".

Parameters

string $s

Returns: string

Definition at line 591 of file DatabaseMysqlBase.php.

References $s.

Referenced by duplicateTableStructure(), and open().

DatabaseMysqlBase::connectInitCharset ( )
