Question

I have a query called AllPosts from a query of a query.

AllPosts has two results:

Row 1| ID: 2   PublishedDate: 2012-05-30 16:47:00.0
Row 2| ID: 3   PublishedDate: 2012-05-31 15:50:00.0

When I do a query of a query on AllPosts called FilterPosts using

WHERE PublishedDate BETWEEN '2012-05-01 00:00:00' AND '2012-05-31 23:59:00'

(Note that the actual query is doing cfqueryparam cf_sql_date for these values)

I expect FilterPosts to have the same rows as AllPosts, instead I only get ID 2. If I change ID 2’s published date to 2012-05-30 23:59:50.0, FilterPosts returns the correct results.

I have also tried

WHERE PublishedDate >= '2012-05-01 00:00:00'   
AND   PublishedDate <= '2012-05-31 23:59:00'   

There is something specifically odd with May 31st.

I’m pulling my hair out here! Thanks!

I tried scratch building a the original query, and oddly enough, same results!

<cfset test = queryNew("Name,PublishedDate", "VarChar, Time" )>
<cfset queryAddRow(test)>    
<cfset querySetCell(test,"PublishedDate","2012-05-30 16:47:00.0")>     
<cfset querySetCell(test,"Name","First Entry")>    
<cfset queryAddRow(test)>    
<cfset querySetCell(test,"PublishedDate","2012-05-31 15:47:00.0")>    
<cfset querySetCell(test,"Name","Second Entry")>    

<cfset StartDate = CreateDate(2012, 5, 1)>

<cfquery name="filter" dbtype="query">    
    SELECT Name, PublishedDate    
    FROM    test
WHERE    1=1
AND PublishedDate >= <cfqueryparam value="#StartDate#" cfsqltype="cf_sql_date">
AND PublishedDate <= <cfqueryparam value="#DateAdd( 'n', -1, DateAdd('m', 1, StartDate) )#" cfsqltype="cf_sql_date">
 </cfquery>

The results of Filter only has ‘FirstEntry’ rather than both like it should.

Answer 1

Oddly enough it had to do with cfqueryparam. I had been using CreateDate() to create my start/end dates like this:

<cfset StartDate = CreateDate(2012,5, 1)>

I was using it in my SQL WHERE in the query of query like this:

WHERE PublishedDate >=  <cfqueryparam value="#StartDate#" cfsqltype="cf_sql_date">

It was cf_sql_date. It should be cf_sql_timestamp The date was capping it to 5-31, and thus anything posted later on in the day on 5-31 was omitted. The minutes were dropping.

Thanks for everyone’s input.

Fixing legacy code rocks!
