How Do I Specify This Type Of Filtering
Sep 10, 2007
I am filtering out rows based on site ID form a maste table which is a foriegn key in all other table. So basically I am filtering out that master table and using join filter I extended the filter to the child tables. But my problem is I have thousands of rows even for a particular site. So, I would like to further filter the rows using a date field in the child tables. But how can I place that date filtering in addition to the extended join filter. If I add another filter for the same table for date column, it seems the two filterings for the same table does not get the AND behaviour. How can I specify two filterings then?

This is nutty. I never got this error on my local machine. The only lower case m in the sql is by near the variable Ratingsum like in line 59.

Happy Friday!
A while since I have posted a question, and this one is probably real easy.
I am trying to store numeric values from a php form in MSSQL 2000 database. However, the columns are set to float and if the value is 1.00, when entered into the table it is saved as 1
If I change the column type to money, the query fails, with an error message of conversion of datatype varchar to datatype money statement terminated.
anybody know what I need to do? do I need to do something in my query to specify that this is NOT varchar data?

I like to define my procedure parameter type to match a referenced table colum type,
similar to PL/SQL "table.column%type" notation.
That way, when the table column is changes, I would not have to change my stored proc.
Any suggestion?

Hi,
The table in SQL has column Availability Decimal (8,8)
Code in c# using sqlbulkcopy trying to insert values like 0.0000, 0.9999, 29.999 into the field Availability
we tried the datatype float , but it is converting values to scientific expressions€¦(eg: 8E-05) and the values displayed in reports are scientifc expressions which is not expected
we need to store values as is
Error:
base {System.SystemException} = {"The given value of type SqlDecimal from the data source cannot be converted to type decimal of the specified target column."}

Implement time interval type in the form of a user defined type in SS2k8r2? Specifically an interval type described in the book Temporal Data and the Relational Model by C. J. Date at all. As an example, an interval is below:
1/4/2006:1/10/2006
which would mean the time period from 1/4 to 1/10.

I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.
I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.
I hope someone can help me work through this.
Thanks in advance,

I have extensively revied both of the design methodologies and I cannot come up with a single clear reason to use one over the other!
Type - Attributes is where you have a table holding the type categories, type, a table holding the type attributes expected and then a table holding the type attribute value:
tbAutombbileCategories
CategoryID | Category
-------------------------------
1 | Car
2 | Truck
3 | Motorcycle
tbAutomobileAttributes
AttributeID | fkCategoryID | Attribute
-------------------------------------------
1 | 1 (car) | Doors
2 | 2 (truck) | Cab
3 | 2 (truck) | Capacity
tbAutomobile
VIN | Category | Make | Model
-------------------------------------
1 | 1 | Honda | Accord
2 | 2 | Ford | F150
tbAutomobileAttributeValues
fkVIN | fkAttributeID | Value
---------------------------------
1 | 1 | 2
2 | 1 | 0
2 | 2 | 1000
Now the above sure is flexible in the sence that a type of automobile can be added without affecting the database schema, but was if some attributes do not take a numeric value? How do you handle computations on attributes specific attributes? Why would I use this structure as opposed to the super type - sub type as shown below?
tbCategories
CategoryID | Category
--------------------------
1 | Cars
2 | Trucks
tbAutomobile (Super Type)
VIN | fkCategoryID | Make | Model
-------------------------------------
1 | 1 |Honda | Accord
tbCars
fkVIN | Doors |
-----------------
1 | 2
tbTrucks
fkVIN | Cab | Capacity
---------------------------
2 | 0 | 1000
Now, adding new sub types probably isn't very flexible but, now you can specify data types for each attribute instead of using sql_variant, which by the documentation cannot be used in aggregate functions and may render poor result when used with ADO.
Regardless of the method used, alot of back end coding is required for computations, what table to send the attributes, etc...
Can anyone please help me clarify. What method is best and why. So far I am leaning for option 2. More work but seems to be more flexible in the sence of customization of each datatype.
E.G., what if you wanted to specify attributes about the cap that can be supplied to trucks?
tbTrucks
fkVIN | Cab | Capacity | fkCapID
--------------------------------------
2 | Y | 1000 | 1
tbCaps
CapID | Vendor | Price | et....
Any thoughts at all? I thought this would have been a pretty damn hot topic!

I'm trying to use the SSIS Execute SQL Task to pull XML from a SQL 2005 database table. The SQL is of the following form:
SELECT
(
SELECT
MT.MessageId 'MessageId',
MT.MessageType 'MessageType',
FROM MessageTable MT
ORDER BY MT.messageid desc
FOR XML PATH('MessageStatus'), TYPE
)
FOR XML PATH('Report'), TYPE
For some reason I can only get this query to work if I use an ADO.NET connection type. If I try to use something like the OLEDB connection I get the following error:
<ROOT><?MSSQLError HResult="0x80004005" Source="Microsoft XML Extensions to SQL Server" Description="No description provided"?></ROOT>
Can anyone tell me why the SELECT ... FOR XML PATH... seems only to work with ADO.NET connections?
Thanks

Hello,
This may be simple, but I can't figure a way to do this. I have the following data returned to a table and need to sum only the items where HDMethod=0 in the table footer. For some reason, something like:
=Sum(Iif(Fields!HDMethod.Value=0, Fields!BDExtended.Value, Nothing)) returns all the rows.
There is a LEFT OUTER JOIN: dbo.[Billing Detail].Item = dbo.[History Detail].Item between the tables touched in the query if that helps.
Thanks for any help you can offer.

Hello --
I am having a UDT problem. When I run the Create Type command. I receive the "could not find type" error. I have seen other posts on here related to the default namespace in VB.NET.

Hi All,
I have following:
a text input for filtering
a gridview that displays the data
an SqlDataSource that contains the query.
Users can either enter something into the text input or leave it blank. Depending on that, the gridview should either display all data (unfiltered, because nothing was entered into the text field) or filtered data (when something is entered).
Now my problem is in defining the query in the SqlDataSource. I could do something like this:
SELECT * FROM myTable WHERE myField = @p1;
and then add in the appropriate <asp:ControlParameter /> under the <SelectParameters> tag. However, this sorta "fixes" the filter. Regardless of whether users actually type something in or not, the filter is in effect. I want it in such a way that if users do not type in anything, the query essentially becomes:
SELECT * FROM myTable;
Is there any way to achieve this?
Thanks in advance,
jason

I'm not sure if this is possible and have been having trouble figuring out the code to do this. I am assigning row_number to a gridview. I then want to filter the results with a dropdown. I am able to get the filter to filter the status but it either renumbers the gridview or it leaves the row numbers blank. Is there a way to have the row_numbers stick to the gridview when I filter? Example below. Thanks
Normal:IssueNumber(row_number), Status1, Open2, Open3, Closed4, Open5, Closed
"Open" Filter:IssueNumber(row_number), Status1, Open2, Open4, Open
"Closed" Filter:IssueNumber(row_number), Status3, Closed5, Closed

Why is Select * from [Merchandise] where [Product Name] like '[ABCD]%'the same as Select * from [Merchandise] where [Product Name] between 'A' and 'D'I can run Select * from [Merchandise] where [Product Name] like 'A%'and get Products that start with the letter "A" but they don't show up when I try to get all "A","B","C","D" Products.

I think I might be missing something here.
Here is what I'd like to do:1. Retrieve a list of data from SQL Server.2. Display that data in a gridview.3. Have the user click on a button to then see a subset of that data. (filtering)
I can't seem to make this work. When the user clicks the button, I need the GridView to update to show only the specified data. In 1.1 I would created a DataView for the filtering, but am trying to use the latest and greatest.
I've seen examples online of people using DropDownLists to act as the dynamic filter parameter. How can I programatically assign this to make it work?Thanks!

Hi,
Our current method of limiting what data a user can see is implemented solely through our Web based business intelligence tools. No filtering is enabled at the database level. This has become somewhat cumbersome as security is tied exclusively to these tools. The tools use one common logon to access the underlying database.
I would like to implement security at the database level (SQL Server 2000) and thereby produce a more flexible/portable solution. I was thinking of setting up individual database accounts for each user and then tying these into our company structure table by passing system_user result to a constraint.
For example System User name 'Store 2' would reference Store '2' in the structure table. Depending on the user, different columns will need to be referenced to filter the rows. A store user would be validated against the store column, an Area Manager user would be validated against the Area Manager column and Head Office users would not be valiadated at all i.e. they are not filtered.
1) What is the best method to implement such a look up. Can or should I use Check constraints for such a solution?
2) Would a UDF be useful?
Any ideas on the best approach to take would be greatly appereciated.
Thanks
Rob

Hello all,
I'm new to SQL Server so if the following sounds stupid then apologies. I am trying to design a query which compares columns and filters according to the result of the comparison. We are a UK based charity that provides financial help to families with disabled children (www.familyfund.org.uk). We have a large database (250,000 entries) which we know contains some duplicate/split files from a recent migration. We need to identify these files but not delete them. Currently I am using the following:
SELECT dbo.Families.famId, dbo.Address.street, dbo.Children.childId, dbo.Address.postcode
FROM dbo.Children INNER JOIN
dbo.Families ON dbo.Children.family_no = dbo.Families.famId INNER JOIN
dbo.Persons ON dbo.Families.famId = dbo.Persons.famId INNER JOIN
dbo.Address ON dbo.Persons.addressId = dbo.Address.addressId
WHERE (NOT (dbo.Children.eligStatus IN (3, 4)))
GROUP BY dbo.Children.childId, dbo.Address.postcode, dbo.Families.famId, dbo.Address.street
HAVING (dbo.Address.street IS NOT NULL)
ORDER BY dbo.Address.street
Obviously this returns all 250,000 records and then we have to search manually. We would like to run a query which compares families.famID to address.street so that where famId has more than one address attched it is returned to the results grid. Does this make sense? is it possible? Any help would be gratefully received
Thanks in advance
Mark

to any who can help:
Here are some rows in a table with their lettered columns:
A B C D E

012345Ae2001-01-26 00:00:00.0002001-01-27 00:00:00.0000
if you notice on the 8 and 9th rows the only difference between them is in
the E column(0 and 1). What I am trying to do here is to display all with
max(E). So in the above example, I should display rows 1-7,9,10 (8th row
will not display because the 9th row has 1 in the E column). this is the
query I have been using on SQL Server 2000 but I keep on displaying all the
rows:
SELECT A,B,C,D,max(E)
FROM <table>
WHERE ( A = '012345A' ) AND
( B >= '01/01/2001' ) AND
( C <= '01/31/2001' )
GROUP BY A,
B,
C,
D
any solutions?
TIA

Hi,
ok, i'm building a page to display a list of courses, a user rating and 'last visited' date.
I have 3 tables -
course (a list of all courses)
review (a list of all ratings)
visit (user visits to each course)
I've put together an SQL statment that returns everything i need, however its not quite right.
SELECT course.courseID, course.courseName, course.courseURL, avg(review.fldRating) AS fldAverage, visit.visitDate
FROM course
LEFT OUTER
JOIN review
ON course.courseId = review.fldcourseId
LEFT OUTER
JOIN visit
ON course.courseId = visit.courseId and visit.userId = 2
GROUP BY course.courseId, course.courseName, course.courseURL, visit.visitDate
ORDER BY course.courseId, visit.visitDate DESC
The problem lies with the fact that each time a user enters a course a new record is inserted into the visit table - so the visit table will show how many times a user has entered a course and on which dates.
this SQL statment returns something like this:
------------------------------------------------
course1 | 5 stars | 10/02/05
------------------------------------------------
course1 | 5 stars | 03/02/05
------------------------------------------------
course2 | 4 stars | 01/01/05
because the user has entered course 1 twice, the list is now showing 2 course1's - how can I change the statemtent to only select the most recent user visit, but still keep the complete list of courses?
I'm a bit of an SQL novice, so appologies if I've not explained this very well,
Thanks in advance,
-------------

Hi,
This is a really complicated issue and is hard to explain but i have the following:
select name, MAX(table2.time) from table1 INNER JOIN table2 on table1.id = table2.id GROUP BY name
which is fine and brings up the correct results but if I want to find out from those records what another field is in table 2 for each record it pulls up too many results (i want just the one result from table 2 and then find what user it is)
if I do..
select name, table2.username MAX(table2.time) from table1 INNER JOIN table2 on table1.id = table2.id GROUP BY name, table2.username
.. it pulls up too many results cos there are different usernames
if i dont group by table2.username then it give an error

@End varchar(50)
as
SELECT TOP 100 PERCENT COUNT(company) AS VisitCount, company
