I am writing a query in Microsoft Access. and I am getting a syntax error in "field description". Here is the code:

CREATE TABLE CONS 
( 
    Com_Type text, 
    Cons_2008 double(10,2), 
    Cons_2009 double(10,2), 
    Cons_2010 double(10,2) 
);

Thanks!

回答1:

CREATE TABLE CONS 
( 
  Com_Type TEXT(150), 
  Cons_2008 DOUBLE, 
  Cons_2009 DOUBLE, 
  Cons_2010 DOUBLE
);

回答2:

Specify the length of the text field, unless you want a field of length 255 when called through an Access query or a Memo field when called through an ADO connection.

Com_Type Text(50), 

The Double type has no size and scale specifications. Either drop them or use the Decimal type.

Cons_2008 Double

Or

Cons_2008 Decimal(10, 2)

Note: See this SO answer for a limitation related to the decimal type.

When using the Double type, you can still specify a format in the TextBoxes linked to this table column. That way you can force the display of 2 decimals.
