CURRENT_TIMESTAMP The CURRENT_TIMESTAMP Function returns the current system date and time from the machine that is hosting the PointBase database as a TIMESTAMP data type. What are Oracle values? VALUE takes as its argument a correlation variable (table alias) associated with a row of an object table and returns object instances stored in the object table. The type of the object instances is the same type as the object table. Oracle Built in Functions. There are two types of functions in Oracle. 1) Single Row Functions: Single row or Scalar functions return a value for every row that is processed in a query. 2) Group Functions: These functions group the rows of data based on the values returned by the query.This is discussed in SQL GROUP Functions.What are Oracle values? VALUE takes as its argument a correlation variable (table alias) associated with a row of an object table and returns object instances stored in the object table. The type of the object instances is the same type as the object table. Oct 02, 2021 · 2) The maximum number of components in the DECODE function, including expr, searches, results, and default, is 255. 3)Oracle automatically converts the values for expression and compare_value to the datatype of the first compare_value. Also the datatype of the return_value is converted to the datatype of the first return_value. IN represents the value that will be passed from outside and OUT represents the parameter that will be used to return a value outside of the procedure. The function must contain a return statement. The RETURN clause specifies the data type you are going to return from the function. function-body contains the executable part.You may use the CURRENT_TIME Function anywhere you specify a time value. Example if the current time is exactly 9:00 AM, the CURRENT_TIME Function returns: 09:00:00. CURRENT_TIMESTAMP The CURRENT_TIMESTAMP Function returns the current system date and time from the machine that is hosting the PointBase database as a TIMESTAMP data type. 26.12 ADD_VALUE Function Signature 1.

So, we can say that a function in Oracle can have a parameter(s) that is optional but a function should always return a value that is mandatory. A function consists of a header and body. The function header has the function name and a RETURN clause that specifies the datatype of the returned value. Each parameter of the function can be either in the IN, OUT, or INOUT mode. For more information on the parameter mode, check it out the PL/SQL procedure tutorialSpecifically the PIPELINED, PIPE ROW, and RETURN clause are discussed. PIPELINED Clause. Within the CREATE FUNCTION clause, there is a new option called PIPELINED. This option tells Oracle to return the results of the function as they are processed, and not wait for a complete execution or completion of the result set.26.12 ADD_VALUE Function Signature 1.
