<function>mysql_select_db</function> 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 <function>mysql_connect</function> was
|
|
called without arguments, and use it.
|
|
</para>
|
|
<para>
|
|
Every subsequent call to <function>mysql_query</function> will be
|
|
made on the active database.
