ORA-1483 Using database type LONG, HELP!

Question

Running on WINNT 4.0, JDK 1.2
When attempting to update a column of type LONG the following
error is being recieved:
java.sql.SQLException: ORA-01483: invalid length for DATE or
NUMBER bind variable
The sql statement is:
UPDATE FSC_HELP_ITEM_DATA SET DATA_OBJ = ? WHERE DATA_ID = ?
Where Data_OBJ is the LONG, and is being set from a String using
setString()
and Data_ID is NUMBER, and is being set from an int with
setInt();
The error occurs when the length of the String is greater than
2000 characters in length.
I have tried setMaxFieldSize(), but not luck there.
I have also tried:
((OracleStatement)stmt).defineColumnType( 1,Types.LONGVARCHAR )
But no luck there either.
NOTE: I do not get the error when inserting the same data values
in a similar fashion
null

Answer 1

I have establishing an Thin connection to a 7.3.4.0.0 database.
The code that performs the update is:
sqlCommand = "UPDATE FSC_HELP_ITEM_DATA SET DATA_OBJ = ?
WHERE DATA_ID = ?";
stmt = DbConnect.conn.prepareStatement( sqlCommand );
stmt.setString( 1, htmlData );
stmt.setInt( 2, newDataId );
stmt.executeUpdate();
stmt.close();
htmlData is type String
newDataId is type int
The table FSC_HELP_ITEM_DATA is:
Name Null? Type
DATA_ID NUMBER
DATA_TYPE CHAR(1)
DATA_OBJ LONG
