sql - C# OleDb INSERT INTO overflow exception -


my query looks this:

insert tblfiles (filename,downloadname,description,length,parts,checksum)  values ('img_0228.jpg','file1','description1'         ,2694310,1925,26931139928208758813621215525179134210220)

i using access database , table looks this:

this exception get:

an unhandled exception of type 'system.data.oledb.oledbexception' occurred in system.data.dll additional information: overflow

i not understand causing this.

the problem column datatype.

you tried insert 26931139928208758813621215525179134210220 number column generate overflow error.

you should change datatype of checksum column string/binary.
