Comma Seperated Query for Multiple Parametes in PLSQL - oracle

Question

I am able to query comma separated IN parameter in PLSQL so far with reference to Query with comma seperated IN parameters in PLSQL. and working perfect. My question how do I implement this same solution for at least 3 comma separated parameters. My query parameters are like this,
I_PRODUCT query (R%, L%)
I_MODEL query (E%,T%,R%)
I_TYPE query (A5,B%,C%)
Is it good to make as a function and call for all these parameters? Any other quick solution?
create or replace PROCEDURE RQUERY1
(
I_PRODUCT VARCHAR2
I_MODEL VARCHAR2
I_TYPE VARCHAR2
, O_Cursor OUT SYS_REFCURSOR
) AS BEGIN
O_Cursor := NULL;
OPEN O_Cursor FOR
WITH PROD_SEARCH AS
(
select regexp_substr(I_PRODUCT,'[^,]+', 1, level) pattern from dual
connect by regexp_substr(I_PRODUCT, '[^,]+', 1, level) is not null
)
SELECT * FROM table1
WHERE EXISTS (SELECT NULL FROM PROD_SEARCH WHERE table1.PRODUCT LIKE pattern );
END RQUERY1 ;
update: I am looking to query the parameters (I_PRODUCT,I_MODEL,I_TYPE) from my java code using stored procedure and need to display the output value.

Answer 1

Use a collection:
CREATE OR REPLACE PROCEDURE RQUERY1
(
I_PRODUCT IN SYS.ODCIVARCHAR2LIST,
I_MODEL IN SYS.ODCIVARCHAR2LIST,
I_TYPE IN SYS.ODCIVARCHAR2LIST,
O_Cursor OUT SYS_REFCURSOR
)
AS
BEGIN
OPEN O_Cursor FOR
SELECT t.*
FROM table1 t
INNER JOIN TABLE( I_PRODUCT ) p ON t.PRODUCT = p.COLUMN_VALUE
INNER JOIN TABLE( I_MODEL ) m ON t.MODEL = m.COLUMN_VALUE
INNER JOIN TABLE( I_TYPE ) y ON t.TYPE = y.COLUMN_VALUE;
END RQUERY1;

Then you can call it in Java like this:
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import oracle.jdbc.OracleCallableStatement;
import oracle.jdbc.internal.OracleTypes;
import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
public class TestDatabase {
public static void main(String args[]){
try{
Class.forName("oracle.jdbc.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:#url:port:sid","UserName","Password");
String[] products = { "Product1", "Product2", "Product3" };
String[] models = { "Model1", "Model2", "Model3" };
String[] types = { "Type1", "Type2", "Type3" };
ArrayDescriptor des = ArrayDescriptor.createDescriptor("SYS.ODCIVARCHAR2LIST", con);
CallableStatement st = con.prepareCall("call TEST.RQUERY1(?,?,?,?)");
st.setArray( 1, new ARRAY( des, con, products ) );
st.setArray( 2, new ARRAY( des, con, models ) );
st.setArray( 3, new ARRAY( des, con, types ) );
st.registerOutParameter( 4, OracleTypes.CURSOR );
st.execute();
ResultSet cursor = ((OracleCallableStatement)st).getCursor(4);
while ( cursor.next() )
{
int id = cursor.getInt(1);
String product = cursor.getString(2);
String model = cursor.getString(3);
String type = cursor.getString(4);
System.out.println( String.format( "Id: %5d", id ) );
System.out.println( String.format( " Product: %s\t", product ) );
System.out.println( String.format( " Model: %s", model ) );
System.out.println( String.format( " Type: %s", type ) );
}
} catch(ClassNotFoundException | SQLException e) {
System.out.println(e);
}
}
}

Edit:
I finally understood what you want.
As described here, you can define multiple with statements. So you can write it like this:
OPEN O_Cursor FOR
WITH PROD_SEARCH AS
(
select regexp_substr(I_PRODUCT,'[^,]+', 1, level) pattern from dual
connect by regexp_substr(I_PRODUCT, '[^,]+', 1, level) is not null
),
MODEL_SEARCH AS
(
select regexp_substr(I_MODEL,'[^,]+', 1, level) pattern from dual
connect by regexp_substr(I_MODEL, '[^,]+', 1, level) is not null
),
TYPE_SEARCH AS
(
select regexp_substr(I_TYPE,'[^,]+', 1, level) pattern from dual
connect by regexp_substr(I_TYPE, '[^,]+', 1, level) is not null
)
SELECT * FROM table1
WHERE EXISTS (SELECT NULL FROM PROD_SEARCH WHERE table1.PRODUCT LIKE pattern )
AND EXISTS (SELECT NULL FROM MODEL_SEARCH WHERE table1.MODEL LIKE pattern );
AND EXISTS (SELECT NULL FROM TYPE_SEARCH WHERE table1.TYPE LIKE pattern );
END RQUERY1 ;
