La fonction NEXT VALUE FOR prend en charge la génération de valeurs de séquence triées en appliquant la clause OVER à l’appel NEXT VALUE FOR. En utilisant la clause OVER , un utilisateur a la certitude que les valeurs retournées sont générées dans l’ordre de la sous-clause ORDER BY de la clause OVER .

The NEXT VALUE FOR function supports generating sorted sequence values by applying the OVER clause to the NEXT VALUE FOR call. By using the OVER clause, a user is guaranteed that the values being returned are generated in the order of the OVER clause's ORDER BY subclause.

Selecting from the sequence gives you a snapshotted value, just like the misnamed/broken currval(). READ UNCOMMITTED or WITH (NOLOCK) would help, as would a currval() implementation that doesn't lie.

La syntaxe pour créer une séquence dans Oracle est la suivante : CREATE SEQUENCE SEQUENCE_NAME. [START WITH {Initial_Value}] [INCREMENT BY {interval}]; {Initial_Value} est la valeur de départ de la séquence, et {interval} est l'intervalle entre les nombres de séquence consécutifs. Les deux champs [START WITH] et [INCREMENT BY] sont facultatifs.

You can obtain the current value and the next value of a sequence using the currval and nextval functions, respectively. These functions are typically used within SQL statements or in PL/pgSQL code. Current Value (currval): To get the current value of a sequence, you need to specify the name of the sequence as an argument to the currval function.

The NEXTVAL pseudocolumn displays the next available value for the sequence. Once a sequence number is selected, the session can access the current value repeatedly using the CURRVAL pseudocolumn.
