I need to pull data from SQL server and write into Delta lake table using synapse pipeline. For timestamp column in SQL server I have tried using string datatype in target delta lake table but it stores junk characters. I have create synapse mapping dataflow to write data into target.

Here is the example of value stored in timestamp column in SQL Server : 0x000000002BAED0C9

Please suggest me the right datatype to use for SQL server timestamp in delta lake table.

    Hi @Anonymous

    In Delta Lake Tables the only accepted formats are:

    Example formats:

    You will need to convert your hexadecimal format to the proper structure as seen above.
