There are several functions in Oracle, such as NVL and NVL2, that perform some kind of logic on the values that are provided. Learn what they all do and see some examples in this article. Oracle Logical Functions in This Guide In this article, we'll look at a few logical functions in Oracle This is an Oracle-only function and is probably the most commonly used by Oracle developers.

  1. NVL und NVL2 sind beides SQL Funktionen, welche häufig in SQL Statements, SQL Prozeduren oder SQL Funktionen benötigt werden. Dieser Beitrag beschreibt den Unterschied zwischen NVL und NVL2. Bei NVL wird lediglich die erste Expression überprüft. Ist diese ungleich NULL wird das Feld ausgegeben. Tritt hier allerdings ein NULL Wert auf, so wird der zweite Ausdruck ausgeführt bzw. ausgegeben
  2. In diesem Oracle-Lernprogramm wird erläutert, wie Sie die Oracle/PLSQL NVL-Funktion mit Syntax und Beispielen verwenden. Beschreibung Die Oracle/PLSQL NVL-Funktion können Sie einen Wert ersetzen, wenn ein Nullwert auftritt.

  4. NVL2 is also an Oracle-specific function, so if you're planning on moving database systems, it's something to consider. The syntax of NVL2 is: NVL2 ( check_value, value_if_not_null, value_if_null ) There are three parameters. The first is the check_value, is also checked for NULL, just like the NVL function. The second parameter, value_if_not_null is returned if the check_value is not NULL.

It accepts three arguments, the first being the column name, the second is the alternate value of the column when it is NOT NULL, and the third is the alternate value when the column value is NULL The Oracle NVL () function in Oracle can be defined as a function which allows the user to replace the null value or an empty string in the result set with a better alternative like a string value and this function returns the not non value of the same data type of the base expression in case the value is not null and it replaces the null or empty string with a different alternative (passed as an argument with the function) in case the original value is null La fonction NVL2 remplace une valeur nulle avec une autre valeur entrée en paramètre. NVL2 prend trois paramètres: NVL2 (arg1, arg2, arg3) La fonction NVL2 retourne arg3 si arg1 est nulle, sinon la fonction retourne arg2
