My table looks like the following
[PartNumber], [FromStep],[ToStep],[MovedDateValue]
Ex.
[Fish], [Step1], [Step2],[1/2/2007]
[Fish[, [Step2], [Step3],[1/3/2007]
It contains all the [FromStep] and [ToStep] that [PartNumber] goes through in the past 3 months.
How would I go about querying for all [PartNumber]'s that took more than 1 day to move from Step 1 to Step 2?... so on and so forth.
I tried the DateDiff Function and the numbers did not work.

Hi, there.
You may try to join the table with itself on records where [PartNumber] is the same and [ToStep] in one table alias is the same as [FromStep] in another. Thus you will obtain dataset with records containing dates of sequential steps, then you may use DateDiff() function. Or you may include day difference in JOIN criteria.
Something like this. -
SELECT t1.[PartNumber], t1.[MovedDateValue], t2.[MovedDateValue] FROM [YourTableName] AS t1 INNER JOIN [YourTableName] AS t2 ON t1.[PartNumber]=t2.[PartNumber] AND t1.[ToStep]=t2.[FromStep] AND DateDiff("d", t1.[MovedDateValue], t2.[MovedDateValue]) > 1;

Fish
If I only had half the smarts you did!
That seem to do the trick. Thanks.
Now if I add:
WHERE t1.[to_order_step_n um]="Step1";
To the end, I will be able to search specific steps that are =>1, correct?

If you ever have records where [ToStep]="Step1", then you will get records for Step1->Step2 movements.

I am fairly new to SQL so sorry if this is a really dumb question.
I have a small (still) SQL database, which I am trying to query from an ASP
page.
The field I am querying is of DATETIME data type, and is populated
automatically using the GetDate() function as a default value.
When I try and search on this field, using a date/time in the format
dd/mm/yyyy hh:mm:ss as the search criteria, it fails with the following

I am working on a project that will have about 500,000 records in an XML

this will make things a lot more complex because the searching needs to go
accross all 500,000 records. Can anyone point me to some best practices...

A finished part can contain multiple sub-parts to make up the finished part.
The sub-parts can also be made up of sub-parts and those sub-parts can also
be made up of sub-parts etc etc.
All parts are contained within the same table and I have a seperate table

Hi Cj,
I also noticed that the "Act" variable here seems hasn't been declared(or
declared anywhere else?). I've try building the same code and got the same
result and the "Operator '+' cannot be applied to operands of type 'string'
" error does pointing to the "Act.Trim" which should be of method call
syntax such as Act.Trim()
After change it, that error is eliminated.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
