Example

IF MyConnection.NoDatabaseAccess("CustomerDatabase") = True THEN
// Specific process
...
MyConnection.EndNoDatabaseAccess("CustomerDatabase")
END
Syntax
<Result> = <Connection>.EndNoDatabaseAccess([<Database>])
<Result>: Boolean
  • True if the access to the specified database (or to all the databases accessed by the connection) is restored,
  • False if an error occurred. HError is used to identify the error.
<Connection>: Connection variable
Name of the Connection variable that describes the connection containing the database to which access must be restored.
<Database>: Optional character string (with quotes)
Name of database for which the access must restored.
If this parameter corresponds to "*", access will be restored for all databases.
If this parameter is not specified, access will be restored for all the databases accessible by <Connection>.
Remarks

Connection to a blocked database

In some cases (power failure for example), the connections to a database may be refused. For example, if a power failure occurs during the execution of this code (before <Connection variable>.NoDatabaseAccess):
// Describe the connection
MyConnection is Connection
 
// Open the connection
MyConnection.OpenConnection()
IF MyConnection.NoDatabaseAccess("CustomerDatabase") = True THEN
Info("Unable to connect to the database")
END

To authorize access again, simply establish a connection without specifying a database and use <Connection variable>.EndNoDatabaseAccess.

Authorizing the access to a database locked by the HFSQL Control Center

When the connections to an HFSQL Client/Server database are refused, access can be granted again using HFSQL Control Center. To do so, perform the following operations:
  • Connect as administrator to the server without specifying the database,
  • Display the "Connections" tab of server,
  • In the ribbon, in the "Connections" group, expand the "Lock of connections" button and select "Authorize all the connections".
