you can check the current value of a sequence in your session by using "currval" sequence.currval will return that. IF you mean "the current value any session would see at that point in time" - you would have to call "sequence.nextval".

Just nu sätter jag bara in om och om igen tills det lyckas ( INSERT INTO tbl (pk) VALUES (sequence.NEXTVAL) ), och det synkroniseras med nästa värde.

Here is a NEXTVAL will return the next value of the sequence u hv defined. The squence. should hv defined as. CREATE OR REPLACE SEQUENCE region_seq. INCREMENT BY 1; Then u can use the sequence to insert a row.

The Oracle NEXTVAL function must be called before calling the CURRVAL function, or an error will be thrown. No current value exists for the sequence until the Oracle NEXVAL function has been called at least once. SEQUENCE statement is used to generate UNIQUE values on particular column in existing table with starting value and increment by value. NEXTVAL statement is used to insert values on existing table by increasing old sequence value with increment by value and returns generated new value. SEQUENCE& NEXTVAL statements are used in ORACLE database. 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. Such a query block can appear in the following A top-level SELECT statement An INSERT SELECT statement (either SQL > Advanced SQL > SEQUENCE And NEXTVAL Oracle uses the concept of SEQUENCE to create numerical primary key values as we add rows of data into a table.

The first twenty values were in the cache but only the first two were actually used. 2009-07-24 In case of a system failure event, you will lose all cached sequence values that have not been used in committed SQL statements.

The NEXTVAL function finds the next value from the specified Oracle sequence. A sequence is a schema object that can generate a unique sequential value. If the sequence does not exist, the sequence will be created in the Oracle database. The value is incremented in the Oracle database each time the sequence is used.

SQL> create sequence seq_example start with 1001 increment by 1 cache 10; The NEXTVAL function finds the next value from the specified Oracle sequence. A sequence is a schema object that can generate a unique sequential value. If the sequence does not exist, the sequence will be created in the Oracle database. The value is incremented in the Oracle database each time the sequence is used. Answer: You can change the LASTVALUE for an Oracle sequence, by executing an ALTER SEQUENCE command.

the next call to NEXTVAL will give you the right result); if you use Toad, press F5 to run the statement, not F9, which pages the output (thus stopping the increment after, usually, 500 rows). NEXTVAL: This gets the next value of the sequence and increments the sequence by its increment value. So, to get the next value of the sequence (for example, to use in an INSERT statement to generate a primary key ), you’ll need to use the NEXTVAL pseudocolumn. Answer: You can change the LASTVALUE for an Oracle sequence, by executing an ALTER SEQUENCE command. For example, if the last value used by the Oracle sequence was 100 and you would like to reset the sequence to serve 225 as the next value. NEXTVAL is incremented once for each row returned by the subquery, regardless of how many occurrences of the insert_into_clause map to each row.
