thanks for the solution.
I want to ask one thing
let say i've created a method in a bean in which i'm passing three parameters.
One is tablename as String, Second is Name of tablefields as Object, Third is Values as Object
Like:
public synchronized int insert(String table,Object[] fields, Object[] values)Ah now we're getting somewhere. I was trying to come up with a situation where using a regular Statement over PreparedStatement would be viable and came up with practically nothing.
In the method body i'm accessing the table fields and values and combining them into the insert sql query.
how can i do this using preparedstatment.
how do i come to know here in this bean that this value is int or string or date at runtime to use setInt, setString, setdate or setBlob respectively.That's your problem. Bad design. You want to make some sort of universal insert method that can insert anything anywhere. But it doesn't really make sense, because whenever you're trying to insert something, you know exactly what you want to insert and where. You could use a PreparedStatement at that point (although encapsulate it in its own method). Now you're trying to create your own poorly designed framework over JDBC that doesn't solve problems, only increases them.
Above was the only reason i saw, i was using statement instead of preparedstatment as statement was looking easy in this situation.
please, give me the solution of above using preparedstatment.No, rather you should reconsider your design. What advantage does your insert() method give you over, let's say using a regular PreparedStatement. Granted, you can put your connection opening and other boilerplate code in the method. But if that's your only problem, then your insert method isn't gonna be much use. You could always switch to JPA for example and work with that.
