When you receive this error it means that the Access Engine is unable to find find one or more of your columns names or the whole table name correctly.

So make sure that the column name you have given is same as table column name.
Is this really a column name MStaus?

Without your DB table definition we can't be sure, but I'd start by checking your spelling. Is MStaus really the column name, or should you have written:

C#

OleDbCommand cmd = new OleDbCommand("Select * from Loan where Plan_Id IS NOT NULL AND MStatus IS NULL ", con);
