Jag vet att Oracle stöder ett databasobjekt som heter SEQUENCE att genom att Återigen, ring bara eseq.nextval i din trigger och du är säker på att ett säkert 

Generate next value for a SEQUENCE. Same as NEXTVAL(). or in Oracle mode (SQL_MODE=ORACLE) sequence_name.nextval Description; See Also. NEXT VALUE FOR is ANSI SQL syntax while NEXTVAL() is PostgreSQL syntax. 30 Oct 2015 You do this by using the CREATE SEQUENCE command, as shown The NEXTVAL attached to CUSTOMER_ID tells Oracle you want the  6 Feb 2014 The SEQUENCE statement introduced in SQL Server 2012 brings the ANSI SQL 2003 Joe Celko explains the basics of using a SEQUENCE. illustrated, and weaknesses of Oracle sequences as is currently implemented.

Suppose if you wanted to reset the sequence to a new value 901, drop it and recreate it. Sequence created. With oracle 10.2g: will set the current sequence value to the max (pk) of your table (i.e. 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). Answer: You can change the LASTVALUE for an Oracle sequence, by executing an ALTER SEQUENCE command.

Good side: this solution is only DML, not DDL. Only SQL and no PL-SQL.

Oracle sequence nextval

Within a single SQL statement, Oracle will increment the sequence only once per row. 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. You would execute the following commands. ops$tkyte@ORA9IR2> select s.nextval from dual; select s.nextval from dual * ERROR at line 1: ORA-02289: sequence does not exist what we want is s @remote site ops$tkyte@ORA9IR2> select s.nextval@ora920 from dual; NEXTVAL-----5 alternatively, we can: ops$tkyte@ORA9IR2> create synonym s for s@ora920; Synonym created. ops$tkyte@ORA9IR2> select s.nextval from dual; The NEXTVAL function finds the next value from the specified Oracle sequence.

Oracle sequence nextval

Assuming that you want to group the data before you generate the key with the sequence, it sounds like you want something like. INSERT INTO HISTORICAL_CAR_STATS ( HISTORICAL_CAR_STATS_ID, YEAR, MONTH, MAKE, MODEL, REGION, AVG_MSRP, CNT) SELECT MY_SEQ.nextval, year, month, make, model, region, avg_msrp, cnt FROM (SELECT '2010' year, Oracle Sequence nextval is jumping number back and forth. I created a new table and a new sequence, I have two C# web services trying to insert records into this table using same query utilizing mySequence.nextval (and yes I checked it many times, they both use mySequence.nextval ). 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. 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. The NEXTVAL function finds the next value from the specified Oracle sequence.

Oracle sequence nextval

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.

An Oracle sequence is a database object that provides unique integer values. The sequence cache size determines how many values Oracle preallocates in memory, in the Shared Pool. A sequence, which generates primary keys, and the table, which consumes the sequence values, are two completely independent Oracle objects. There is no restriction about the integration ways.

Alternatively, you can use Identity columns; see: reference doc; articles: Enhancements in Oracle DB 12cR1 (12.1): Default Values for Table Columns and Identity Columns in 12.1; E.g., Oracleの順序(Sequence)の生成(CREATE SEQUENCE)と取得(SELECT NEXTVAL)に関する説明。伝票番号の様な連続したユニークな数値を発生させる機能。NEXTVALで次の順序の値を取得する。CURRVALで現在の順序の値を取得する。 Use NOCYCLE if you want the sequence to stop generating the next value when it reaches its limit. This is the default.

Eveytime sequence.nextval is called , the sequence will be incremented by the Incremented by parameter of the sequence. My question seems easy but i haven't found a solution. I'm using the nexval sequence in a insert SQL script but we have errors because the LAST_NUMBER value haven't been updated and its value is not NEXTVAL generates and returns the next sequence number while CURRVAL can be used to refer to that value as needed. Oracle does not support batch queries to return data as SQL Server does. You can, however, return the sequence value by setting the return value of a stored procedure. But does Proc SQL allow me to select the transaction data from a SAS dataset and at the same time access the Oracle connection to select values from the Oracle sequence object?

If the sequence does not exist, the sequence will be created in the Oracle database.
