Is it possible to alter column to decimal in MS Access 2007+?

Question

Is it possible to alter column to decimal in MS Access 2007+? This is my code: ALTER TABLE [test] ALTER COLUMN [columnName] DECIMAL(18,1)

Answer 1

Its not possible in query of ms access but in OLEDB its possible.

Answer 2

DECIMAL(18,1) is no Access datatype. Either you link it to an MSSQL Server or you use a MS Access datatype.

Here you will find a msdn article on MS Access datatypes (use the types in the second column for your ALTER Query)

ALTER TABLE [test] ALTER COLUMN [columnName] LONG
