How to pass ARRAY to Oracle Procedure

Question

Hi
We are using BC4J with JSP in our project. We need to send an Array to the procedure.
Could somebody provide some info as how this can be achieved.

Answer 1

A while back, I used a SQLJ client to call a Java (also SQLJ) stored procedure and I needed to pass an array of strings to the procedure. I did something like this:
Java Class that was loaded in DB:
public class MyClass
// method that the stored procedure uses
public static void CALL_DOSTUFF(String a,
oracle.sql.ARRAY b,
oracle.sql.ARRAY c)
String[] bb = (String[])b.getArray();
String[] cc = (String[])c.getArray();
doStuff(a,bb,cc);
public static void doStuff(String a,
String[] b,
String[] c)
// process the input
In the database I added the type:
create or replace type STR_ARRAY as table of varchar2(20);
and the procedure:
create or replace procedure CALL_DOSTUFF(a varchar2,
b STR_ARRAY,
c STR_ARRAY)
as
language java
name 'MyClass.CALL_DOSTUFF(java.lang.String,
oracle.sql.ARRAY,
oracle.sql.ARRAY)';
I then used jpub to publish a STR_ARRAY.java file. I compiled this and used it with my SQLJ client to call to the stored procedure. The STR_ARRAY constructor takes a String[], so you do something like this in the SQLJ client:
String x = "X";
String y = {"y1","y2"};
String z = {"z1","z2"};
STR_ARRAY y1 = new STR_ARRAY(y);
STR_ARRAY z1 = new STR_ARRAY(z);
#sql {CALL CALL_DOSTUFF(:x,:y1,:z1)};
Hope this helps.
