HModifyDatabaseRights (Function)
In french: HModifieDroitBaseDeDonnées
HFSQL Client/ServerAvailable only with this kind of connection
Modifies the rights granted to a user or to a group for a HFSQL Client/Server database.
Remark: to find out the rights granted to a group or to a user on an HFSQL Client/Server database, use HInfoDatabaseRights.
// Copy the rights from a user to another one
sRights is string
sRights = HInfoDatabaseRights(MyConnection, "Moore", hRightsRead + hRightsInsert, "MyDatabase")
HModifyDatabaseRights(MyConnection, "Moore", hRightsRead + hRightsInsert, sRights, "MyDatabase")
<Result> = HModifyDatabaseRights(<Connection> , <User or group> , <Rights to modify> , <New values> , <Database>)
<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.
Remark: HErrorInfo will return an "Unknown user" or "Unknown group" error if the current user does not have the rights to see the users (hRightsSeeUser constant) and if he wants to get information about another user or another group.
<Connection>: Character string or Connection variable
Connection for which the rights granted to a user or to a group of users must be modified. This connection corresponds to:
<User or group>: Character string
Name of the user or group whose rights must be modified.
<Rights to modify>: Integer constant (or combination of constants)
List of rights to modify:
hRightsAutoModifRights to perform the automatic modification of data files on a data file.
hRightsBackupRights to perform a backup.
hRightsChangeLinkRights to modify the integrity rules on a data file.
hRightsChangeOwnerRights to modify the owner of an element.
hRightsChangeRightsRights to change rights.
hRightsConnectionRights to connect to a server (encrypted or unencrypted connection).
hRightsCreateFileRights to create a data file (with HCreation).
hRightsCreateViewRights to create an SQL view or a materialized view.
hRightsDebugRights to debug the stored procedures.
hRightsDeleteRights to delete the records from a data file.
hRightsDeleteDBRights to delete a database.
hRightsDeleteFileRights to delete a data file (HDeleteFile).
hRightsDeleteViewRights to delete a view.
hRightsEncryptedConnectionRights to connect to a server (encrypted connection only).
hRightsInsertRights to add new records into a data file.
hRightsLockRights to lock the data files or the records of a data file.

hRightsManageDuplicateRights to enable and disable the management of duplicates.
hRightsManageIntegrityRights to enable and disable the management of integrity.
hRightsManageProcedureRights to add, modify and delete the sets of procedures.
hRightsManageTriggerRights to add, enable and delete server triggers.
hRightsNoDatabaseAccessRights to prevent access to a database (HNoDatabaseAccess and HEndNoDatabaseAccess).
hRightsReadRights to read the records of a data file.
hRightsRunProcedureRights to run a stored procedure.
hRightsUpdateRights to modify the records of a data file.
<New values>: Integer constants
Lists the 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 user will inherit from the value of the rights granted to the group to which he belongs.
<Database>: Character string
Name of the database for which the rights must be modified.

When are rights changed?

The change is effective as soon as HModifyDatabaseRights is run. There is no need to restart the server to take the new rights into account.
Managing duplicates and integrity: The error does not occur when the management mode is modified but when an attempt is made not to comply with the integrity constraint (or with the duplicate constraint).
