Question

please guys, i need an sql query to select data from an access database using vb6. the query will only provide current date and the filed been compaired is curr_date in the database.

for example

SELECT * 
  FROM TABLE 
 WHERE curr_date BETWEEN firstoflastmonth AND endoflasthmonth;

SELECT * 
  FROM TABLE 
 WHERE curr_date BETWEEN firstoflastweek AND endoflasthweek;

SELECT * 
  FROM TABLE 
 WHERE curr_date BETWEEN firstofthismonth AND endofthismonth;

SELECT * 
  FROM TABLE 
 WHERE curr_date BETWEEN firstofthsiweek AND tilldate;

The problem i have figuring ot is how to specify the two dates in comparison

Answer 1

Is it not easiest to just check wich month/week you want it to be in then?

From you examples:

SELECT *    FROM TABLE   
WHERE curr_date BETWEEN firstoflastmonth AND endoflasthmonth;  

This would become (with the month function used)

SELECT *    FROM TABLE   
WHERE month(curr_date) = month(dateadd("m",-1,Date()));

This compares the month of your curr_date to the month of Date (the current date) minus one month, so the last month.
This can also be done using datediff:

SELECT *    FROM TABLE   
WHERE DateDiff ( "m", curr_date, date()) = 1
AND curr_date < date();

The last line is added to make sure that dates one month later are not selected.

Same thing can be applied to the other queries using the date function found here
