passing Execute Sql Task Result set object to For Each Loop container

i have written a oracle query in Script Task and assigned it to string variable. This is my query 

string oracle_query = "SELECT bank_ID, Branch_ID, Trans_NUM, Trans_DT, convert(Varchar(25),quantity) AS quantity  FROM OPENQUERY(orcale_server_name,  'SELECT * "
                + "FROM oracletable" +
                 " where bank_ID =''" + Dts.Variables["User::bank_ID"].Value.ToString() + "'' AND Trans_DT = ''" + Dts.Variables["User::Trans_DT"].Value.ToString() + "'' AND quantity = " + Dts.Variables["User::quantity"].Value.ToString() + " AND Branch_ID = ''" + Dts.Variables["User::Branch_ID"].Value.ToString() + "'' ')";

the result of this query has been assigned to string variabl which i have declared in my package 

Dts.Variables["oraclequery"].Value = oracle_query; .

output of this query is 

bank_ID  Branch_ID  Trans_Num  Trans_DT   Quantity  
12         13       12AS566    2012-01-01  4000

Based on Trans_Num column i need to update one more table.

Instead of script task i can use oledb TranFormation, but while passing Running parameters in Oledb Source, no data is coming.

So the result of script task i have assigned to OracleQuery varibale and passed as source variable in Execute Sql Task and resultset as Full Result Set .

This Execute SQl Task resultset i have passed to for each loop container and inside varibale index i have assigned OracleQuery Varibale.

but still no data is populating

1.First you need to create variables for the column being retrieved from your oracle query

2.Then the variable oraclequery should be of type System.Object

3.In the resultSet tab of Execute SQL task assign the result to the variable oraclequery 

ResultName    VariableName 
 0            oraclequery

4.Then in the ForEach Loop use ADO Enumerator and select ADO Object SourceVariable to oraclequery and click the radio button Rows in the First Table

In the variable mapping of for each loop, map the columns in the same order as it is being retrieved from the query .

 Variable     Index 
  BankId       0
  Branch_ID    1 
 ....          ..

Now you can access these variable inside inside a DFT placed in the Foreach loop and then use OLEDB component to update another table based on the Trans_Num
