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 whenever an HFSQL function is run. A trigger is defined by HDescribeTrigger. For more details, see Managing the triggers.
// In the initialization code of the project
TriggerResult is boolean
// Create a trigger for the all the analysis data files
TriggerResult = HDescribeTrigger("*", "HADD,HMODIFY," + ...
"HDELETE, HCROSS,HWRITE", "CheckUserRights", hTriggerBefore)
// "CheckUserRights" is a global procedure of the project
IF TriggerResult = False THEN
Error("Error on a trigger: " + HErrorInfo)
// Disables the trigger for all the data files
// On HDelete and HCross
HDeactivateTrigger("*", "HDELETE,HCROSS")
<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.

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: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.
