HListServerTrigger (Function)

In french: HListeTriggerServeur

Lists the different triggers available on a connection or on one of the connection files.

Note Server trigger manipulation functions are advanced functions. The server triggers can be created directly in the data model editor. For more details, see Server triggers.

Syntax

<Result> = HListServerTrigger(<Connection> [, <Physical HFSQL Client/Server files>])

<Result>: Character string

List of server triggers applied to the specified connection. The different triggers are separated by CR characters (Carriage Return).
The list has the following format:
<Trigger> + TAB + <Data file> + TAB + <WLanguage procedure> + TAB +
<Function number> + TAB + <Type of trigger> + TAB + <Trigger status> + CR +...
<Trigger> Name of trigger.
<Data file> Physical name of the data file to which the trigger applies.
<WLanguage procedure> Name of the stored WLanguage procedure called by the trigger.
<Function number> Identifier of WLanguage function on which the server trigger is enabled.
To find out the name of WLanguage function used, see the ListeDéfinitionHF.WL file (found in the "Personal\External\" subdirectory of WINDEV, WINDEV Mobile or WEBDEV).
<Type of trigger>
"A" for a "BEFORE" trigger (the procedure associated with the trigger is run before the HFSQL function of trigger).
"P" for an "AFTER" trigger (the procedure associated with the trigger is run after the HFSQL function of trigger).
<Trigger status>
"1" for an active trigger (HActivateServerTrigger),
"0" for an inactive trigger (HDeactivateServerTrigger).

<Connection>: Optional character string or Connection variable

Connection to use. 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.

<Physical HFSQL Client/Server files>: Optional character string

Physical name of one or more HFSQL Client/Server data files associated with the connection ("CUSTOMER.FIC" for example). To specify several names, the names of the data files must be separated by a comma (",").
If this parameter is not specified or is an empty string (""), the trigger will be enabled on all the data files of the database.
