sesam_connect

Open SESAM database connection ()
bool sesam_connect ( string catalog, string schema, string user )

Establishes a connection to a SESAM database handler task. The connection is always "persistent" in the sense that only the very first invocation will actually load the driver from the configured SESAM OML PLAM library. Subsequent calls will reuse the driver and will immediately use the given catalog, schema, and user.

Parameters

catalog

When creating a database, the "catalog" name is specified in the SESAM configuration directive //ADD-SQL-DATABASE-CATALOG-LIST ENTRY-1 = *CATALOG(CATALOG-NAME = catalogname,...)

schema

The schema references the desired database schema (see SESAM handbook).

user

The "user" argument references one of the users which are allowed to access this "catalog" / "schema" combination. Note that "user" is completely independent from both the system's user id's and from HTTP user/password protection. It appears in the SESAM configuration only.

Return Values

Returns TRUE on success or FALSE on failure.

Examples
