The creation of Oracle stored procedures using JAVA is often used in our development. The following describes how to use JAVA to write Oracle stored procedures in detail. I hope you will be enlightened.
Let's take a look at how to use JAVA to compile the Oracle stored procedure. We will write statements in Oracle SQL plus.
I. Start SQL PLUS
Ii. Compile a JAVA class and define a JAVA class name. This stored procedure outputs the Square Value of the input parameter.
Create or replace and compile java source named "PF"
/**
* Using JAVA classes to create an Oracle storage process
*/
Package org. oraclejava. pro;
Public class javaCreatePro {
Public static String test (int num ){
Return num + ":" + num * num;
}
}
Iii. Create the method test in the JAVA class as an Oracle Function Method
Create or replace function PF_FUN (name integer) return varchar2 as language java name'org. oraclejava. pro. javaCreatePro. test (java. lang. Integer) return
Java. lang. String ';
Iv. directly call the created Oracle function on the console
Select PF_FUN (10) from dual;
V. output results
10 square meters: 100
