Filter by Computed Column

  

Hello!


After looking for a driver to open legacy dbf drivers to connect, the next level trouble a have is this one:


first, i can retrieve the data but when trying to filter by a parameter (somesc columns) i get an error.

The error says about the database can't determine some blah blah!

The error is a columm tha is formated (  1234  ) about  8 space, fixed. The values in the query appears like that. I resolve this by Trimming Ltrim(ColumnName) and i get this (1234).

Now in SqlExpress, how can i filter by the new Trimmed Expression? (This is a primary key that the DBF use)

Sample:

SELECT column1, column2, column3
TABLE FoxProDB

Now 

SELECT Ltrim(column1) as NewExp, column2, column3
TABLE FoxProDB
Where NewExpre = @NewExpres                  -Error-


Thanx!


Computed Column

  
This is the forst time i am going to work with computed columsn. Is there a way computed columns not store the data in the table? If yes, how would i build my query when creating a computed column? By using Persisted, does it mean that i am storing the values in the database or going to do calculations on the fly  Thanks

Lookup column uses ID instead of Title in rule formula

  
I have two SP lists: Partner and Request. Partner just has a Partner Name column, plus the ID column. In Request, I have a lookup column pointing to the Partner list. There is also a Title column and a Request Date column. When I set up the lookup I set it to get info from the Partner list’s Partner Name column, not the ID column.   I made an InfoPath form to make a new Request, with the Partner being selected from a Drop-Down List Box. When this form is submitted, I would like to change the Title field to be a string concatenation of Partner Name, a comma, and the Request Date. I made a rule to do this. Example of what I want: “Partner A, 8/27/2010”.  However, the result is that the Partner ID is used instead of the Partner Name and what I get is “1, 8/27/2010”.   (More: In production I would use the Form Submit rule to do this. For development I used a rule that runs when the field changes. If I change the Drop-Down List Box properties Value property (on the data tab) from d:ID to d:Title the string is formatted as desired, but the form won’t submit and shows a tooltip that only positive integers are allowed.)   How can I make the rule use the Partner Name column in the formula for the rule, instead of the ID?   Thank you, James.

Importing text file datetime string into SQL datetime column

  

Hi,

Using SSIS 2008 R2 to import text files.  Two of the fields contained are datetime values in the format "2010-09-24 18:58:29.220".  Ultimately both the date and time need to be extracted with precision to the second, at the very least.  When I import the text file, however, the time value seems to get truncated before the date value's being imported, for an imported result of "2010-09-24 00:00:00.000".

Is my problem with the Flat File Connection Manager?  Regardless of which DataType choice I use for the properties of my datetime values--I've tried every form of date datatype--the imported column values contain the correct date but the wrong time value.

Is there an easy way to import a text file datetime value straight into a datetime column?  Is it possible, or am I trying to shortcut what should be a proper process?

Thanks,
Eric


Importing text file datetime string into SQL datetime column

  

Hello,

I'm importing a text file into SQL Server 2008 R2 using SSIS 2008 R2.  Included in the text file is a datetime column with values like "2010-09-24 18:58:29.220".  However, when I import the file, the stored value has the time portion replaced with what I assume is the default, such as "2010-09-24 00:00:00.000".

Is there an easy way to import a datetime value from a text file into a datetime column in my table?  I've tried every form of date datatype in the Flat File Connection Manager, but I still keep getting the correct date portion with the incorrect time portion.

Am I trying to do something that wasn't intended?  I see Todd McDermid's page (http://toddmcdermid.blogspot.com/2008/11/converting-strings-to-dates-in-derived.html) and am starting to wonder if perhaps I'm trying to shortcut something that I shouldn't.

Thanks,
Eric
