Read Limit Listbox based on a drop down box by Brent @ 9/11/2012

Awesome 2nd option worked. Could you find time in your busy days to create a mini tutorial on the different ways on writing SQL with VBA I seem to find most of my problems with the duble quotes and single quotes going in the right place depending on how many lines my SQL spans and what is on what line. I would pay to understand this concept in great detail.

Reply from Richard Rost:

I wasn't thorough enough in the SQL Seminar? The general rule of thumb is that you use a single quote or double-double-quotes inside of regular double-quotes to form a string. Like:

"SELECT * FROM MyTable WHERE FirstName='" & FN & "'"

or

"SELECT * FROM MyTable WHERE FirstName=""" & FN & """"

Access converts both of those strings into:

SELECT * FROM MyTable WHERE FirstName="Joe"

Easy enough?

Read Limit Listbox based on a drop down box by Brent @ 9/8/2012

I am having problems with my quotes in my SQL can someone help?

BidList.RowSource = "SELECT BidID, JobName, JobCity, JobNumber, BidDate, ClientName, PropPrice " & _
        "FROM PropT " & _
        "WHERE YEAR(BidDate)=' & YearCombo' " & _
        "ORDER BY " & Forms!PropListF!SortBy

BidList.RowSource = "SELECT BidID, JobName, JobCity, JobNumber, BidDate, ClientName, PropPrice " & _
"FROM PropT " & _
"WHERE YEAR(BidDate)='" & YearCombo & "' " & _
"ORDER BY " & Forms!PropListF!SortBy

However if your YearCombo is a NUMBER then you don't need those quotes:

BidList.RowSource = "SELECT BidID, JobName, JobCity, JobNumber, BidDate, ClientName, PropPrice " & _
"FROM PropT " & _
"WHERE YEAR(BidDate)=" & YearCombo & " " & _
"ORDER BY " & Forms!PropListF!SortBy

The YEAR function returns a number... so try the 2nd one first.

Read Limit Listbox based on a drop down box by Brent @ 9/6/2012

I have a listbox that I want filtered depending on a combo box on the form. The combo box (YearCombo) has five values (2008,2009,2010,2011,2012) these values come from a year table that I can add future years to when they happen. By default I want it to filter by current year.

My SQL for my BidLIst on my form (PropListF) in the On Open event is as follows:

BidList.RowSource = "SELECT BidID, JobName, JobCity, JobNumber,         BidDate, ClientName, PropPrice " & _
        "FROM PropT ORDER BY " & Forms!PropListF!SortBy

BidDate (Date Field) needs to equal that year in the combobox, the best senario would be to use the current system date and filter back only 6 months as well as the years. I am trying to limit by listbox to under 200 records.

Reply from Richard Rost:

Try adding a WHERE clause to your SQL:

...WHERE YEAR(BidDate)=" & YearCombo

To set YearCombo to the current year onOpen, just say

YearCombo = YEAR(Now())
