HViewToFile (Function)

In french: HVueVersFichier

Available only with this kind of connection

Warning
From version 20, the SQL views and the materialized views are available.
The views handled by this function correspond to the former mechanism of views. They do not correspond to SQL views or to materialized views.

Note: This operation can be performed only if the view was created with the hViewLocking constant (which means that the records imported into the view have been locked in the data file). After the call to HViewToFile, the records are unlocked in the source file of view.

Note: From version 19, HFSQL is the new name of HyperFileSQL.

HViewToFile(CUSTOMER34)

IF HViewToFile(CUSTOMER13) <> True THEN
Error("Unable to save the modifications performed on the view")
END

Syntax

<Result> = HViewToFile(<View name>)

<Result>: Boolean

True if the view was transferred into the data file,
False otherwise. HError returns more details about the problem.

<View name>: Character string (with or without quotes)

Name of view used. If this name is not specified, HViewToFile handles the last view used by the last function for HFSQL management (starting with the letter H).

Remarks

If an error occurs when updating the data file, HError is used to identify the records that caused the problem. All you have to do is browse the view again and check HError on each record found in the view.
