Ashish,

Instead of using place markers to "hold a spot" for a variable number of
values, you could build the entire SQL statement, including the actual
values, and then prepare that statement and execute it.

For example,

sqlStatement = "select * from mytable where line in (";

sqlStatement = sqlStatement + "'ABC',";
// Repeat previous statement for each value you need to check for. The last
value should not include the trailing comma after the close single-quote.

sqlStatement = sqlStatement + ")";

Then just prepare that statement and execute it.

PrepareStatement is quite expensive and only needed if you either have ?-placeholders or want to repeat it _MANY_ times. The value for _MANY_ varies from database to database, but I believe it was between 20 and 50 for Oracle some years ago.
