Progress 4GL Reference

DYNAMIC-CURRENT-VALUE statement

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

Syntax

DYNAMIC-CURRENT-VALUE( sequence-exp, logical-dbname-exp ) = expression

sequence-exp

A character expression that evaluates to the name of a sequence.

logical-dbname-exp

A character expression that evaluates to the name of a connected database in which the sequence is defined.

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, Progress returns an error, and the sequence value remains unchanged.

Notes

If logical-dbname-exp contains the Unknown value (?), Progress generates a runtime error.
You cannot set a sequence to the Unknown value (?).
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 static versions.
