How to compare dates in the WHERE clause of an SQL used in Excel VBA accessing MS Project File with OLE DB?

Question

In Excel VBA, I am accessing a Microsoft Project 2003 file as a DB through MS OLE DB provider (Microsoft.Project.OLEDB.11.0). When I shoot an SQL to this which uses string comparisons in the WHERE clause like, TaskName='Coding', it works. But when I compare dates in the WHERE clause, like TaskStart > '07/08/06' or TaskStart > 07/08/06 or TaskStart>#07/08/06#, it does not work. Please let me know how to code the WHERE clause when comparing dates.

Answer 1

Are you sure you are formatting the date properly, and the task_start field is the correct datatype?

Write yourself a query without a filter on the task_start field that returns the task_start value in the result-set, so you can copy/paste that value (as an example of the format) into another SQL query, where you modify the sample-date to match your filter-by date.

Vba Compare Dates

Answer 3

try to convert them to unix timestamp format (number of seconds from January 1st, 1970). there should be a function that does this for you (and back from it). then the comparison is easy, you just compare integers, and you can easily do date manipulations (ie 1 day = 86400 seconds)

Answer 4

You may use the access query tool "Advanced Access Builder" at http://www.download5000.com/page25449.aspx , it allows you to visually build complete SQL scripts.

I am a database development programer, you use some tools and learn sql(struct query language ). You can get one tool of Advanced SQL Builder at http://www.dlkj.net/sqlBuilder/ . My email is [e-mail]. OK?
