Is is possible to pass oracle object type to java stored procedure. Here's what i have so far.
Java stored procedure:
create or replace and compile java source named Example as
import java.sql.SQLData;
import java.sql.SQLException;
import java.sql.SQLInput;
import java.sql.SQLOutput;
public class Example {
public static void test(ExObj obj) {
System.out.println(obj.client);
}
public static class ExObj implements SQLData {
public String client = "";
public String sql_type = "EXAMPLE_OBJECT";
public ExObj(String client, String sql_type) {
this.client = client;
this.sql_type = sql_type;
}
/* IMPLEMENTS SQLData */
public void setSqlType(String sqlType) {
sql_type = sqlType;
}
public void writeSQL(SQLOutput stream) throws SQLException {
stream.writeString(this.client);
}
public String getSQLTypeName() {
return sql_type;
}
public void readSQL(SQLInput stream, String sqlTypeName) throws SQLException {
sql_type = sqlTypeName;
this.client = stream.readString();
}
}
}
Oracle procedure:
CREATE OR REPLACE PROCEDURE example(ex_obj in example_object)
AS LANGUAGE JAVA
NAME 'Example.test(java.sql.Struct)';
Oracle object type:
create or replace type example_object as object(
client varchar2(40)
)
Script to call procedure:
declare
l_output DBMS_OUTPUT.chararr;
l_lines INTEGER := 1000;
l_obj example_object;
begin
DBMS_OUTPUT.enable(1000000);
DBMS_JAVA.set_output(1000000);
l_obj := example_object('client');
example(l_obj);
DBMS_OUTPUT.get_lines(l_output, l_lines);
FOR i IN 1 .. l_lines LOOP
-- Do something with the line.
-- Data in the collection - l_output(i)
DBMS_OUTPUT.put_line(l_output(i));
END LOOP;
end;
When running script i get:
ORA-29531: no method test in class Example
ORA-06512: at "EXAMPLE", line 1
ORA-06512: at line 17
I presume it's because oracle object_type doesn't map to java class correctly. Is there a way to do this and if so what am i doing wrong?
The below mentioned issue with your code can be the reason.
1) You must declare a varaible of type
of your object
so that you can use it. You cannot directly use object
as a datatype
. See below :
Demo:
create or replace type example_object as object(
client varchar2(40)
);
/
--Created a type of the object
create or replace type x is table of example_object;
/
CREATE OR REPLACE PROCEDURE example(ex_obj in X)
AS
begin
DBMS_OUTPUT.put_line('Example.test(java.sql.Struct');
DBMS_OUTPUT.put_line('Inside the Procedure');
DBMS_OUTPUT.put_line (ex_obj(1).client);
end;
/
DECLARE
l_output DBMS_OUTPUT.chararr;
l_lines INTEGER := 1000;
l_obj x := x();
BEGIN
DBMS_OUTPUT.enable (1000000);
--DBMS_JAVA.set_output (1000000);
--You need to mention the position where the record will be saved in table.
l_obj.extend();
l_obj(1) := example_object('client1');
example (l_obj);
DBMS_OUTPUT.put_line (l_obj(1).client);
DBMS_OUTPUT.get_lines (l_output, l_lines);
FOR i IN 1 .. l_lines
LOOP
-- Do something with the line.
-- Data in the collection - l_output(i)
DBMS_OUTPUT.put_line (l_output (i));
END LOOP;
END;
