RepeatableReadSupported (Property)

In french: RepeatableReadSupporté

Available only with this kind of connection

The Property RepeatableRead Supported allows to:

Find out whether the data file (file defined in the data model editor or by programming) can be used in HFSQL Client/Server in a transaction that includes a "Repeatable Read" isolation mode.
Allow the use of a transaction that includes a "Repeatable Read" isolation mode for a data file (when the file is described by programming only).

Caution: if this option is enabled, the file is not compatible with versions 18 and earlier.

This property corresponds to the option "Allow the REPEATABLE READ transactions (requires HFSQL version 19 or later)", in the "Details" tab of the file description window in the analysis.

Example

IF RepeatableReadSupported = False THEN Info("Repeatable Read mode cannot be used")
