You can use NEXTVAL (or CURRVAL) in the Values clause of an INSERT statement, as the following example shows: INSERT INTO tab1 (col1, col2) VALUES (seq_2.NEXTVAL, seq_2.NEXTVAL); In the previous example, the database server inserts an incremented value (or the first value of the sequence, which is 1 ) into the col1 and col2 columns of the table. SQL> select test.nextval from dual; NEXTVAL ----- 50 SQL> select test.nextval from dual; NEXTVAL ----- 51 SQL> Bear in mind that if you want to reset it so that the next value will be 1, your sequence must be created with a minvalue of 0 to allow it to be reset this way (the default minvalue is 1 I think). Then use the next sequence value + 4999 values at a go. If the sequence was created with the CACHE option, altering the sequence will recreate the cache.. Sequences objects are created by using the CREATE SEQUENCE statement. [SequenceName] AS [bigint] START WITH 410014104 INCREMENT BY 1 MINVALUE 410000000 MAXVALUE 419999999 CYCLE CACHE GO. SELECT LAST_NUMBER FROM ALL_SEQUENCES WHERE SEQUENCE_NAME = 'seq_name'; ALTER SEQUENCE seq_name INCREMENT BY 100; -- Value to reach desired value - 1 SELECT seq_name.nextval FROM dual; -- Reinitialize value to desired ALTER SEQUENCE seq_name INCREMENT BY 1; -- Back to init step If not, every NEXT VALUE usage will cause changes in the stored SEQUENCE table. Launch SSMS GUI and connect to your database 2. On the MS SQL server how to achive this? FromSql requires entity type or keyless entity type, and ExecuteSqlRaw / ExecuteSqlInterpolated are the "modern" bridge to ADO.NET ExecuteNonQuery which returns the affected rows. Within a single SQL statement containing a reference to NEXTVAL, Oracle increments the sequence once: For each row returned by the outer query block of a SELECT statement If any of these locations contains more than one reference to NEXTVAL, then Oracle increments the sequence once and returns the same value for all occurrences of NEXTVAL. By writing the following: CREATE SEQUENCE supplier_seq. Notes. SQL Server SEQUENCE Basics - Simple Talk 7. Let's look at an example using the Animal table with the Id column as the auto-increment column.
