HModifyViewRights (Function)
In french: HModifieDroitVue
HFSQL Client/ServerAvailable only with this kind of connection
Sets the rights granted to a user or group on an SQL view or on a materialized view.
Remark: It is possible to find out the rights of a group or a user on a SQL view or on a materialized view using the HInfoViewRights function.
Example
// Copie des droits d'un utilisateur à un autre 
sDroits is string
sDroits = HInfoViewRights("MaConnexion", "Dupont", ...
	hRightsRead + hRightsInsert, "MaBase", "MaVueClient")
HModifyViewRights("MaConnexion", "Durand", ...
	hRightsRead + hRightsInsert, sDroits, "MaBase", "MaVueClient")
Syntax
<Result> = HModifyViewRights(<Connection> , <User/Group> , <Rights to modify> , <New values> , <Database> , <View>)
<Result>: Boolean
  • True if the rights have been modified,
  • False otherwise. HErrorInfo is used to identify the error.
No modification is performed if the new value is already assigned to the specified rights.
Note: An "Unknown User" or "Unknown Group" error will be returned by the HErrorInfo function if the current user does not have the user viewing right (constant hDroitVisualisationUtilisateur) and is requesting information about another user or group.
<Connection>: Character string or Connection variable
Connection for which the rights granted to a user or group of users should be modified. This connection corresponds to:
<User/Group>: Character string
Name of the user or group whose rights should be modified.
<Rights to modify>: Integer constant (or combination of constants)
List of rights to modify:
hRightsChangeRightsRights to change rights.
hRightsDeleteRights to delete records from a view.
hRightsDeleteViewRights to delete a view.
hRightsInsertRights to add records to a view.
hRightsMaintenanceRights to start a re-index operation or a statistical calculation on a materialized view.
hRightsReadRights to read the records of a view.
hRightsUpdateRights to modify the records of a view.
<New values>: Integer constants
List of new values for the modified rights. New values must be assigned to all the rights specified in <Rights to modify> (in the same order).
If a single value is indicated in this parameter, it will be assigned to all the rights specified in <Rights to modify>.
The possible values are as follows:
hAllowedThe relevant rights are granted to the user or group.
hForbiddenThe relevant rights are not granted to the user or group.
hInheritThe right is undefined at this level for the user (or the group to which they belong). The HFSQL server uses the right defined at the top level for the user (or the group to which the user belongs). For a view, the HFSQL server uses the right defined for the user (or the group to which the user belongs) at database level.
<Database>: Character string
Name of the database containing the SQL view or the materialized view for which the rights must be modified.
  • If the database corresponds to the one defined in the connection, this parameter can correspond to an empty string ("").
  • A WLanguage error occurs if no database is defined in the connection and if this parameter corresponds to an empty string.
<View>: Character string
Name of the SQL view or materialized view for which the rights must be modified.
Remarks

When are rights changed?

Rights are modified when HModifyViewRights is run. There is no need to restart the server to apply the new rights.
