HDescribeConnection("MyConnection", "Julia", "Password", ...
"MyHFServer", "MyDatabase", hAccessHFClientServer, hORead)
// Open the connection
HOpenConnection("MyConnection")
// Delete the database
HDeleteDatabase("MyConnection")

Syntax

<Result> = HDeleteDatabase(<Connection> [, <Database>] [, <Options>])

<Result>: Boolean

True if the database was deleted,
False if an error occurred. HError is used to identify the error.

<Connection>: Character string or Connection variable

Connection for which the database must be deleted. This connection corresponds to:
the name of the connection defined in the data model editor or with HDescribeConnection or HOpenConnection.
the name of a variable of type Connection.

<Database>: Optional character string

Name of the database to delete.
If this parameter is not specified, the database defined in the connection will be used. A WLanguage error occurs if no database is defined in the connection.

<Options>: Optional Integer constant (or combination of constants)

By default, when deleting the database, the files corresponding to the logs are not deleted and the files corresponding to the transactions are deleted. This parameter is used to modify this behavior:
hDeleteLog Deletes the log files and all logged operations.
hKeepTRS Stores the transaction files.
