fbsql_db_status

Get the status for a given database (PHP 4 >= 4.1.0, PHP 5)
int fbsql_db_status ( string database_name [, resource link_identifier ] )

说明

Returns: An integer value with the current status.

fbsql_db_status() requests the current status of the database specified by database_name. If the link_identifier is omitted the default link_identifier will be used.

The return value 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.
