Please anyone help me

You can read the data using varchar and then convert it into Timestamp if the column value is not null.

But.. Some times The value in Timestamp filed will be null. What would be the correct way to read a column with type timestamp which can have nul values also????

If Timestamp column is having null values then correct way to read the timestamp column will be using varchar datatype and then convert it into Timestamp. If value is null then use setnull() function to set the null values.

If Timestamp column is having null values then correct way to read the timestamp column will be using varchar datatype and then convert it into Timestamp. If value is null then use setnull() function to set the null values.
If IsNotNull(d3) Then StringToTimestamp(d3) Else SetNull()

Hi Nirdesh ,
I have done as u said . But still i am getting a warning as follows

Sequential_File_3: When checking operator: When validating export schema: At field "d2": Exporting nullable field without null handling properties

I have set prperty to Nullable in the output file and done an ISNULL check and setnull() . still i am getting the above warning

Set the NullFieldValue in Format tab under the default value in target sequential file. Set it to "".

Check the extended properties of the column with which you having the problem and enter the correct entry in null field value
