(PHP 4 >= 4.0.7, PHP 5)
fbsql_db_status — Get the status for a given database
说明
int fbsql_db_status
( string $database_name
[, resource $link_identifier
] )
参数
-
database_name
-
The database name.
-
link_identifier
-
A FrontBase link identifier
returned by fbsql_connect() or
fbsql_pconnect().
If optional and not specified,
the function will try to find an open link to the FrontBase server and if no
such link is found it will try to create one as if
fbsql_connect() was called with no arguments.
返回值
Returns an integer value with the current status. This can be one of the
following constants:
-
FALSE - The exec handler for the host was invalid. This error will
occur when the link_identifier
connects directly
to a database by using a port number. FBExec can be available on the
server but no connection has been made for it.
-
FBSQL_UNKNOWN - The Status is unknown.
-
FBSQL_STOPPED - The database is not running. Use
fbsql_start_db() to start the database.
-
FBSQL_STARTING - The database is starting.
-
FBSQL_RUNNING - The database is running and can be
used to perform SQL operations.
-
FBSQL_STOPPING - The database is stopping.
-
FBSQL_NOEXEC - FBExec is not running on the server
and it is not possible to get the status of the database.
