Get current value from a SQL Server SEQUENCE

Question

I want to get the current value from my sequence - the same value that is shown in the sequence properties window SQL Server Management Studio

My sequence is created with this statement:

CREATE SEQUENCE [OrderNumberSequence]
    as int
    START WITH 4000
    INCREMENT BY 1
    MINVALUE 0
    NO MAXVALUE
    NO CACHE;
GO

I have tried this SQL from MSDN – but the result is that my number is increasing with 5 for every time I run the query

DECLARE  
  @FirstSeqNum sql_variant
, @LastSeqNum sql_variant
, @CycleCount int
, @SeqIncr sql_variant
, @SeqMinVal sql_variant
, @SeqMaxVal sql_variant ;

EXEC sys.sp_sequence_get_range
@sequence_name = N'[OrderNumberSequence]'
, @range_size = 5
, @range_first_value = @FirstSeqNum OUTPUT 
, @range_last_value = @LastSeqNum OUTPUT 
, @range_cycle_count = @CycleCount OUTPUT
, @sequence_increment = @SeqIncr OUTPUT
, @sequence_min_value = @SeqMinVal OUTPUT
, @sequence_max_value = @SeqMaxVal OUTPUT ;

-- The following statement returns the output values
SELECT
  @FirstSeqNum AS FirstVal
, @LastSeqNum AS LastVal
, @CycleCount AS CycleCount
, @SeqIncr AS SeqIncrement
, @SeqMinVal AS MinSeq
, @SeqMaxVal AS MaxSeq ;

Is there a way that I can get the value without changing the number?

Answer 1

You can select the current_value from sys.sequences:

SELECT current_value FROM sys.sequences WHERE name = 'OrderNumberSequence' ;

Answer 2

If you are using PostgreSQL, you can use this:

SELECT last_value FROM <sequence_name>;
