mssql_select_db — Select MS SQL database
Descrierea
bool mssql_select_db
( string $database_name
[, resource $link_identifier
] )
mssql_select_db() sets the current active database on the server that's associated with the specified link identifier.
Every subsequent call to mssql_query() will be made on the active database.
Parametri
- database_name
-
The database name.
To escape the name of a database that contains spaces, hyphens ("-"), or any other exceptional characters, the database name must be enclosed in brackets, as is shown in the example, below. This technique must also be applied when selecting a database name that is also a reserved word (such as primary).
- link_identifier
-
A MS SQL link identifier, returned by mssql_connect() or mssql_pconnect().
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 mssql_connect() was called, and use it.
Valorile întroarse
Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eşecului.
Exemple
Example #1 mssql_select_db() example

mssql_select_db('php', $link);
?>

Use of square brackets to enclose the database name is also necessary if the name contains a dot: '.'
e.g.
mssql_select_db('Company.ERP');
Produces the error:
Warning: mssql_select_db(): Sybase: Server message: Could not locate entry in sysdatabases for database 'Company'. No entry found with that name. Make sure that the name is entered correctly. (severity 16, procedure N/A) in
mssql_select_db('[Company.ERP]');
Will select successfully

mssql_select_db() seems to truncate the databasename at the length of 30 characters. In my example the following error occured:
mssql_select_db("VeryLongDatabaseNameWhichIsReallyLong", $this->dbConn);
Warning: mssql_select_db(): message: Could not locate entry in sysdatabases for database 'VeryLongDatabaseNameWhichIsRea'. No entry found with that na
me. Make sure that the name is entered correctly. (severity 16) in...
A shorter databasename solved this issue.
