Answer 1

Odbc data provider is not support blob data type at DB2. I suggest you OleDB data provider.

Answer 2

As suggested, ODBC .Net data provider doesn't support this, but there is a workaround if you look here...

Workaround

Set the CLI/ODBC LongDataCompat keyword to 1. Doing so will force the CLI driver to make the following data type mappings to data types the ODBC .NET Data Provider will understand:

• SQL_CLOB to SQL_LONGVARCHAR
• SQL_BLOB to SQL_LONGVARBINARY
• SQL_DBCLOB to SQL_WLONGVARCHAR

To set the LongDataCompat keyword, run the following DB2 command from a DB2 command window on the client machine: db2 update cli cfg for section common using longdatacompat 1 You can also set this keyword in your application, using the connection string as follows:

[C#]

OdbcConnection con = new OdbcConnection("DSN=SAMPLE;UID=uid;PWD=mypwd; LONGDATACOMPAT=1;");

For a list of all the CLI/ODBC keywords, refer to the "UID CLI/ODBC configuration keyword".
