Select Count query in DB2 with Array

Question

I am trying to Count all records in my DB2 database with a query where is uses the contents of an Array to search the Table.

           string[] strNumbers = txtNumbers.Text.Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);

               string strSearch = "";
                   strSearch = "SELECT COUNT(*) FROM TABLENAME WHERE NUMBER = '" + strNumbers + "' AND COMMENT = '" + strMessage + "'";

                DB2Command cmdSearchTable = new DB2Command(strSearch, db2Connection);

                int nodeCount = 0;
                nodeCount = int.Parse(cmdSearchTable.ExecuteScalar().ToString());

if (nodeCount == 0) {
 Not Found          
 } else
  { Found
   }

This code throws up an exception ({"The value of a host variable in the EXECUTE or OPEN statement is out of range for its corresponding use."})

However if I use strNumbers.Length it doesn't throw up an error but the nodeCount it still 0.

Do I need to loop it or is it something else? The query and database connection is fine as I am able to Select,Insert into the database from the same program.

Thanks

EDIT - I have managed to solve this (See accepted answer) but now have a another problem. Lets say '1234567' is in the database once it will return 1 which is fine. If the input it '5551234' which isn't in the database it returns 0 which is also fine. However the problem lies with if the input is '1234567,5551234' the Count will return 1 as 1234567 is in the database, even though 5551234 isn't.

Is there a way of outputting 1 for 1234567 and then 0 for 5551234?

Try changing

WHERE NUMBER = '" + strNumbers + "' AND

with

WHERE NUMBER IN (" + strNumbers + ") AND

Make sure that strNumbers is comma separated. Something like this '12345', 12346', '12347' or 12345,12346,12347 depending on the datatype of the field NUMBERS.
