HDeactivateTrigger (Function)

In french: HDésactiveTrigger

Not available with this kind of connection

Disables a trigger. Then, this trigger can be re-enabled by HActivateTrigger.

Reminder A trigger is a WLanguage procedure automatically called by the HFSQL engine each time an HFSQL function is executed. A trigger is defined by HDescribeTrigger. For more details, see Trigger management.

Example

// Dans le code d'initialisation du projet
LOCAL
	ResultatTrigger is boolean
// Création du Trigger pour tous les fichiers de données de l'analyse
ResultatTrigger = HDescribeTrigger("*", "HAJOUTE,HMODIFIE," + ...
		"HSUPPRIME,HRAYE,HECRIT", "VerifDroitUtilisateur", hTriggerBefore)
// Avec "VerifDroitUtilisateur" une procédure globale du projet
IF ResultatTrigger = False THEN
	Error("Erreur sur un trigger : " + HErrorInfo)
	RETURN
END
...
// Désactive le trigger pour tous les fichiers de données
// Sur les fonctions HSupprime et HRaye
HDeactivateTrigger("*", "HSUPPRIME,HRAYE")

Syntax

<Result> = HDeactivateTrigger([<List of data files> [, <List of functions>]] [, <Type>])

<Result>: Boolean

True if the operation was performed,
False if a problem occurs. HError is used to identify the error.

<List of data files>: Optional character string

Logical name of one or more data files.
To specify several names of data files, the names of the data files must be separated by a comma (",").
To use all the data files found in the analysis, this parameter must be equal to "*".

By default, all the data files are taken into account.

<List of functions>: Optional character string

Name of one or more HFSQL or TableXXX functions on which the trigger must be implemented. To specify several names of functions, the names of functions must be separated by a comma (","). You have the ability to define triggers on the following HFSQL functions:
HModify
HAdd
HDelete
HWrite
HCross
If <List of functions> is set to "*", all the HFSQL functions that can activate a trigger are taken into account.

By default, all the HFSQL functions that can activate a trigger are taken into account.

<Type>: Optional Integer constant

Indicates the type of trigger. All triggers are affected if this parameter is not specified.
hTriggerAfter The procedure is run after the HFSQL function.
hTriggerBefore The procedure is run before the HFSQL function.
