HCancelAlias (Function)
In french: HAnnuleAlias
ODBCNot available with this kind of connection
Cancels an alias previously declared with HAlias. After this operation, the data file associated with the alias is no longer recognized by the HFSQL engine.
Remark: If the alias file is open, it is automatically closed during the cancellation.
Example
// Create 2 aliases on the CUSTOMER data file
HAlias(CUSTOMER, CUSTOMER1)
HAlias(CUSTOMER, CUSTOMER2)
// Cancel the first alias
HCancelAlias(CUSTOMER1)
Syntax
<Result> = HCancelAlias(<Alias file>)
<Result>: Boolean
  • True if the operation was performed,
  • False if a problem occurs. HError is used to identify the error.
<Alias file>: Character string
Name of the alias file to cancel. A non-fatal WLanguage error occurs if the alias file does not exist.
Remarks
When cancelling an alias (HCancelAlias):
  • modifications made with HChangeName and HChangeDir are not cancelled. If the alias is described again, these parameters are stored and re-applied.
  • if a data file has been created with a name given by HChangeName and a location given by HChangeDir, the data file is not physically deleted.
