An identifier that specifies the name of a sequence defined in the Data Dictionary.
logical-dbname
An identifier that specifies the logical name of the database in which the sequence is defined. The database must be connected. You can omit this parameter if the sequence name is unambiguous. If more than one connected database has a sequence with given name, then you must supply logical-dbname.
tenant-id
An integer expression that evaluates to the tenant ID of a regular tenant, including the default tenant (0). This option applies only to a multi-tenant sequence specified by sequence and is intended for access primarily by a super-tenant user.
If you are a regular-tenant user and you specify tenant-id, the specified tenant must be the same as the tenant associated with the database connection identity for logical-dbname or the AVM raises a run-time error.
If you are a super-tenant user and you do not specify tenant-id, the function assumes the effective tenant ID (GET-EFFECTIVE-TENANT-ID function).
If the sequence specified by sequence is non-multi-tenant (a shared sequence in a multi-tenant database), and you specify tenant-id, the option is ignored.
expression
An integer expression assigned as the current value of the specified sequence. If expression is outside the boundary set by the initial value (at one end) and the lower limit or upper limit (at the other end) for the sequence, the AVM returns an error, and the sequence value remains unchanged.
Example
The following example resets the current value of the NextCustNum sequence to the CustNum value of the last Customer record if that is a valid value for the sequence:
r-curvl1.p
FIND LAST customer NO-LOCK.
IF Customer.CustNum < CURRENT-VALUE(NextCustNum) AND
Customer.CustNum > 1000 THEN DO:
CURRENT-VALUE(NextCustNum) = Customer.CustNum. MESSAGE "The value of NextCustNum has been changed to"
Customer.CustNum VIEW-AS ALERT-BOX INFORMATION BUTTONS OK.
END.
ELSE
MESSAGE "The value of NextCustNum remains"
CURRENT-VALUE(NextCustNum) VIEW-AS ALERT-BOX INFORMATION BUTTONS OK.
Notes
The user must have CAN-WRITE privileges on the _Sequence table to use the CURRENT-VALUE statement.
The value of a sequence set by the CURRENT-VALUE statement persists in the database until the next CURRENT-VALUE statement or NEXT-VALUE function is invoked for the sequence, or until the sequence is deleted from the database.
You cannot set a sequence to the Unknown value (?).
If sequence is a multi-tenant sequence in the database, each regular tenant has their own current value of the sequence. So, each tenant that invokes this statement can set their own current values, which can be the same or different than the current values set by other tenants. If the sequence is shared in a multi-tenant database, any current value set by this statement is shared by all tenants in the database.
Caution: Be very careful using multi-tenant sequences when you are updating shared tables or multi-tenant tables for a tenant group. For more information, see the sections on using multi-tenant-enabled sequences in OpenEdge Development: Programming Interfaces
You can use any combination of the NEXT-VALUE function, CURRENT-VALUE function, CURRENT-VALUE statement, and their dynamic versions. Use the dynamic version when you don't know what the database name or sequence name is at compile time.
The user must have CAN-WRITE privileges on the _Sequence table to use the CURRENT-VALUE statement.
