# msql_select_db

(PHP 3, PHP 4 , PHP 5)

msql_select_db -- Select mSQL database

## Description

bool msql_select_db ( string database_name [, resource link_identifier])

msql_select_db() sets the current active database on the server that's associated with the specified link_identifier. If no link identifier is specified, the last opened link is assumed. If no link is open, the function will try to establish a link as if msql_connect() was called, and use it.

成功回傳`TRUE`失敗回傳`FALSE`。

Subsequent calls to msql_query() will be made on the active database.

For downward compatibility, the alias named msql_selectdb() may be used. This, however, is deprecated and not recommended.

See also msql_connect(), msql_pconnect(), and msql_query().
