Inserting nulls

[Gayathri Neti]

Hai Java Gurus,
The question may soud dumb but ...let me ask. I have a varchar column and in my program I have a string variable that take sdata from thr textbox in the gui and inserts it into database. My problem is if th evalue in text box is empty then it is entering empty string into database. I want it to enter nothing.....I canno tchange any database setting and database I am using is Sql server.
Thanks,

Hi Gayathri,
If you are using a "java.sql.PreparedStatement" to insert the data into your database, then you can use the "setNull()" method to set a column value to null -- assuming that you want to set the column to null if nothing has been entered into the "textbox".
I suggest you read the javadoc for the "setNull()" method.
Hope this helps.
Good Luck,
Avi.

If you are using PreparedStatement then you may try this.
PreparedStatement ps=null;
...
...
if(textString == null)
{
ps.setNull(1, java.sql.Types.VARCHAR);
}
else
{
ps.setString(1,textString);
}
