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 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: | | | hRightsChangeRights | Rights to change rights. | | hRightsDelete | Rights to delete records from a view. | | hRightsDeleteView | Rights to delete a view. | | hRightsInsert | Rights to add records to a view. | | hRightsMaintenance | Rights to start a reindex operation or a statistical calculation on a materialized view. | | hRightsRead | Rights to read the records of a view. | | hRightsUpdate | Rights 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:
| | | hAllowed | The relevant rights are granted to the user or group. | | hForbidden | The relevant rights are not granted to the user or group. | | hInherit | The 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.
