Parameters
const wchar_t *database,
const wchar_t *ident,
const wchar_t *password,

|
database |
in |
The name of the database to connect to. If this is null, a connection to the default database is created. |
|
ident |
in |
The ident associated with the session to create. This parameter may not be null. |
|
password |

The password of the ident. A null value is identical to a zero length password. Database servers which do not enforce authentication control may ignore the password. |
|
sessionhandle |
out |
A session handle identifying the session when calling MimerEndSession, MimerBeginStatement, MimerBeginStatement8, MimerBeginStatementC, MimerBeginTransaction, MimerExecuteStatement, MimerExecuteStatement8, MimerExecuteStatementC and MimerEndTransaction. |

A negative value indicating an error, or zero if successful.

Notes
This routine interacts with the database server.
A session handle may or may not have been returned. MimerEndSession should therefore always be called to avoid handle leaks.
Micro API compatible.
