dbSetDatabaseName#

Purpose#

Sets the connection’s database name. To have effect, the database name must be set before the connection is opened. Alternatively, you can dbClose() the connection, set the database name, and call dbOpen() again.

Format#

dbSetDatabaseName(db_id, database_name)#

Parameters:

db_id (scalar) – database connection index number.
database_name (string) – the name to apply to the specified database connection.

Remarks#

For the OCI (Oracle) driver, the database name is the TNS Service Name.

For the ODBC driver, the name can either be a DSN, a DSN filename (in which case the file must have a .dsn extension), or a connection string.

For example, Microsoft Access users can use the following connection string to open an .mdb file directly, instead of having to create a DSN entry in the ODBC manager:

// Add ODBC to list of database connections
db_id = dbAddDatabase("ODBC");

// Set database name
dbSetDatabaseName(db_id, "DRIVER=
   {Microsoft Access Driver (*.mdb)};
   FIL={MS Access};
   DBQ=myaccessfile.mdb");

// Open database
dbOpen(db_id);
