ConnectionInterface.php

Initializes the database connection/settings.

Connect to the database.

Create a persistent database connection.

Keep or establish the connection if no queries have been sent for a length of time exceeding the server's idle timeout.

Returns the actual connection object. If both a 'read' and 'write' connection has been specified, you can pass either term in to get that connection. If you pass either alias in and only a single connection is present, it must return the sole connection.

Select a specific database table to use.

Returns the name of the current database being used.

Returns the last error encountered by this connection. Must return this format: ['code' => string|int, 'message' => string] intval(code) === 0 means "no error".

The name of the platform in use (MySQLi, mssql, etc)

Returns a string containing the version of the database being used.

Orchestrates a query against the database. Queries must use Database\Statement objects to store the query and build it. This method works with the cache. Should automatically handle different connections for read/write queries if needed.

Performs a basic query against the database. No binding or caching is performed, nor are transactions handled. Simply takes a raw query string and returns the database-specific result id.

Returns an instance of the query builder for this connection.

Returns the last query's statement object.

"Smart" Escaping Escapes data based on type. Sets boolean and null types.

Allows for custom calls to the database engine that are not supported through our database layer.

Determines if the statement is a write-type query or not.
