BTI_API PvModifyDatabase(

BTI_LONG hConnection,

BTI_CHAR_PTR dbNameExisting,

BTI_CHAR_PTR dbNameNew,

BTI_CHAR_PTR dictPath,

BTI_CHAR_PTR dataPath,

BTI_ULONG dbFlags);


In	hConnection	Connection handle that identifies the server. Connection handles are obtained with the PvConnectServer() function.
In	dbNameExisting	Name of the existing database
In	dbNameNew	Name of the new database. Set this parameter to NULL if you want the database name to remain unchanged.
In	dictPath	Dictionary path.
In	dataPath	Data path. Set this value to NULL to use the default data path (that is, the same as the dictionary path) If you want to modify a database to include MicroKernel Engine data files located in multiple paths, specify this parameter as a semicolon (;) delimited list. For example: C:\data\path1;C:\data\path2
In	dbFlags	Database flags, which can be a combination of the P_DBFLAG_ constants. P_DBFLAG_RI (enforce integrity constraints, including referential integrity and triggers) P_DBFLAG_BOUND (stamps the database name on the dictionary files so only that database can use them) P_DBFLAG_DBSEC_AUTHENTICATION (use database security authentication, Mixed security policy. See Btrieve Security Policy.) P_DBFLAG_DBSEC_AUTHORIZATION (use database security authorization, Database security policy. See Btrieve Security Policy.) P_DBFLAG_LONGMETADATA (use V2 metadata. See Metadata Version.)


P_OK	The operation was successful.
P_E_INVALID_HANDLE	Invalid connection handle.
P_E_NULL_PTR	Call with NULL pointer
P_E_ACCESS_RIGHT	Insufficient access right for the operation
P_E_NOT_EXIST	Named database does not exist on the server.
P_E_FAIL	Failed for other reasons.

The following precondition must be met:

•

DTI session started by calling PvStart().

•

Connection established by PvConnectServer(), or if you are performing the operation on a local machine, P_LOCAL_DB_CONNECTION may be used as the connection handle.

Btrieve Security Policy

The following table indicates how to specify a security model in a new database, or to interpret the security model of an existing database. Using any other combination of flags for security will result in status code 7024.


This Flag Combination	Represents this Security Model
No flags	Classic
P_DBFLAG_DBSEC_AUTHENTICATION	Mixed
P_DBFLAG_DBSEC_AUTHENTICATION P_DBFLAG_DBSEC_AUTHORIZATION	Database
