在Access 2007中向查询添加表达式的正确语法（

Question

I came across this How Do I Sequentially Number Records in an Access Query in order to do what I was trying to do based on this stackoverflow question I posted (which I never got to do what I was after) but each time that I try to add the AS Counter to the query I get

The expression you entered contains invalid syntax
You may have entered an operand without an operator

using the following sql:

SELECT Maintable.NumBR, Maintable.*, [Ehow] AS Expr1
FROM Maintable
WHERE (((Maintable.[NumBR])="" 
  Or (Maintable.[NumBR]) Like "3101" 
  Or (Maintable.[NumBR]) Like "3541" 
  Or (Maintable.[NumBR]) Like "4381" 
  Or (Maintable.[NumBR]) Like "AS3281" 
  Or (Maintable.[NumBR]) Like "4260" 
  Or (Maintable.[NumBR]) Like "4315" 
  Or (Maintable.[NumBR]) Like "4330" 
  Or (Maintable.[NumBR]) Like "4382" 
  Or (Maintable.[NumBR]) Like "9410" 
  Or (Maintable.[NumBR]) Like "9570" 
  Or (Maintable.[NumBR]) Like "AS3710" 
  Or (Maintable.[NumBR]) Like "AS4450" 
  Or (Maintable.[NumBR]) Like "K400" 
  Or (Maintable.[NumBR]) Like "3100" 
  Or (Maintable.[NumBR]) Like "3130" 
  Or (Maintable.[NumBR]) Like "3280" 
  Or (Maintable.[NumBR]) Like "3495" 
  Or (Maintable.[NumBR]) Like "3540" 
  Or (Maintable.[NumBR]) Like "3610" 
  Or (Maintable.[NumBR]) Like "3700" 
  Or (Maintable.[NumBR]) Like "4110" 
  Or (Maintable.[NumBR]) Like "4200")

AND (([Ehow])=DCount("[NumBR]","[Maintable]"," [NumBR] <= " & [NumBR])));

EDIT the question posed in the previous stackoverflow question answers this question.

Answer 1

The AS Counter phrase is not needed in your query. In the linked example, that's added to the SELECT statement to alias the column; in your example you're working with the WHERE clause, so that AS phrase wouldn't do anything (and is actually invalid).
