HInfoViewRights (Function)
In french: HInfoDroitVue
HFSQL Client/ServerAvailable only with this kind of connection
Allows you to find out the rights granted to a user or to a group on an SQL view or on a materialized view.
sRights is string
sARight is string
// Retrieves the read/add rights granted to the usernamed Moore
// on MyCustomerView found in MyDatabase
sRights = HInfoViewRights("CNT", "Moore", hRightsRead + hRightsInsert, ...
"MyDatabase", "MyCustomerView")
sARight = ExtractString(sRights, firstRank, TAB)
WHILE sARight <> EOT
CASE hAllowed
CASE hForbidden
CASE hInherit
sARight = ExtractString(sRights, nextRank, TAB)
<Result> = HInfoViewRights(<Connection> , <User/Group> , <Rights> , <Database> , <View> [, <Display mode>])
<Result>: Character string
  • Requested information,
  • Empty string ("") if an error occurred.
  • "Unknown user" or "Unknown group" if the current user has no permissions to see other users (hRightsSeeUser constant) and wants to get information about another user or group.
In hDefault mode, <Result> is a list of values separated by tabs. Each value in the list corresponds to the rights requested by <Rights>. The values in the list can correspond to one of the following constants:
hAllowedThe relevant rights are granted to the user or group.
hForbiddenThe relevant rights are not granted to the user or group.
hInheritThe user belongs to at least one group to which the relevant rights were granted.
This constant is returned only if the display mode is not set to hEffective.

In hDetails mode, <Result> is a list of values with the following format:
<Relevant rights 1> + TAB + <Value of rights 1> + CR + ...
<Relevant rights N> + TAB + <Value of rights N> + CR

The rights correspond to the constants used in the <Rights> parameter and the values of the rights correspond to the hAllowed, hForbidden or hInherited constant (see the above table).
<Connection>: Character string or Connection variable
Connection for which the rights of a user or group of users must be known. This connection corresponds to:
<User/Group>: Character string
Name of the user or group whose rights must be known.
<Rights>: Integer constant (or combination of constants)
List of rights to find:
hRightsAllList of all the rights.
We recommend that you use this constant in hDetails or hEffective + hDetails display mode.
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.
<Database>: Character string
Name of the database containing the SQL or materialized view with the rights that must be known. 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 on the server for which the rights must be known.
<Display mode>: Optional Integer constant
Result display mode:
(Default value)
The rights returned do not take the inherited rights into account (rights granted to the groups to which the user belongs).
If no rights were defined, the value will be set to hInherit.
<Result> contains the values of the requested rights (in the same order).
hDetailsSame as hDefault.
<Result> contains the rights and there value.
hEffectiveThe rights returned correspond to the rights that will be actually granted to the user or to the group on the view. The inherited rights are taken into account (rights granted to the groups to which the user belongs for example).
hEffective + hDetailsSame as hEffective.
<Result> contains the rights and there value.
