Access (Property)

In french: Accès

Not available with these kinds of connection

The Access property is used to manage the type of access of a connection (HFSQL Client/Server, OLE DB, etc.). You can:

Find out the type of access used for a connection (HFSQL Client/Server, OLE DB, etc.).
Define the type of access used for the connection (HFSQL Client/Server, OLE DB, etc.). In this case, if the connection is currently opened, it will be closed then re-opened with the new parameters during a first access to a data file that is using this connection.

Remark: The connection can correspond to:

a connection described in the data model editor,
a connection described by HConnect, HDescribeConnection or HOpenConnection.
a connection described by a Connection variable.

Example

MyConnection is Connection
// Describe the connection
MyConnection.User = "USER"
MyConnection.Password = "PASSWORD"
MyConnection.Server = "MYSERVER"
MyConnection.Database = "Database"
MyConnection.Provider = hAccessHFClientServer
MyConnection.Access = hOReadWrite
MyConnection.ExtendedInfo = "Extended information"
MyConnection.CursorOptions = hClientCursor

HOpenConnection(MyConnection)
