ABL Syntax Reference : DYNAMIC-CURRENT-VALUE statement


Resets the current integer value of a sequence defined in the specified database.


  sequence-exp , logical-dbname-exp [ , tenant-id ] ) = expression
A character expression that evaluates to the name of a sequence.
A character expression that evaluates to the name of a connected database in which the sequence is defined.
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-expression 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-expression 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-expression is non-multi-tenant (a shared sequence in a multi-tenant database), and you specify tenant-id, the option is ignored.
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.


*If logical-dbname-exp contains the Unknown value (?), the AVM generates a run-time error.
*You cannot set a sequence to the Unknown value (?).
*If sequence-exp 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.
*The user must have CAN-WRITE privileges on the _Sequence table to use the DYNAMIC-CURRENT-VALUE statement.
*The value of a sequence set by the DYNAMIC-CURRENT-VALUE statement persists in the database until the next DYNAMIC-CURRENT-VALUE statement or DYNAMIC-NEXT-VALUE function is invoked for the sequence, or until the sequence is deleted from the database.
*You can use any combination of the DYNAMIC-NEXT-VALUE function, DYNAMIC-CURRENT-VALUE function, DYNAMIC-CURRENT-VALUE statement, and their non-dynamic versions.
