Thanks

WHERE CASE @Variable1 WHEN 0 THEN T1.Field1 <= Value1 AND WHEN 1 THEN T1.Field1 >= Value2 AND WHEN NULL THEN T1.Field1 >= Value3 AND END T2.Field2=@Variable2 AND
so on
Can i select the statement that should be executed? i tried even inserting all the WHERE clausoles into 3 different IF, but he continues showing me errors...
Honestly i have to say that i'm pretti noob at SQL...
Thank U.

Selecting Table Names In A SQL Statement
Jun 12, 2001Hey all,
I trying to figure out if you can get a list of table names from a particular database by writing a single SQL statement.
E.G. In Oracle, from SQLPlus - you can say:
Select table_name from user_tables;
Is there anything like that SQL that I could run from Query Analyser to get a list of table names from a particular SQL Server database?
Thanks in advance,
Tommy
Selecting A Range Of Records In A SQL Statement
Feb 12, 2005I want to run a query that returns say 100 records...but I only want to return first 10 for first page on a web page, then on page 2 the webpage will return rows 11 to 20 of the same SQL statement...page 3 returns rows 21 to 30 rows etc....(eg. like Google or bulletin boards, browsing auctions in ebay etc.).
I could probably get my application logic to handle this (ASP.net), for instance I could possibly get a datareader to skip the first 10, output the next 10 then stop for page 2 (records between 11 amnd 20) but is there way to do this in SQL Server at the database level using an SQL Statement?
I can use TOP 10 to get the first set of records for the first page eg.
SELECT TOP 10* FROM Suppliers
...but how do I get between 11 and 20, 21 and 30 and so on?
I've already mentioned I could handle this in my application logic, but then each time the same SQL Statement is fetching all 100 records, even though the web page will only display a certain range. I'm building an intranet website that can potentially run queries that return 100'000s records, even though initially only top 20 or so records are display, each page they subsequently go to will rerun that same query that returns all 100'000 records. So handling this as part of the query would be better for performancr I reckon.
Someone gave me the syntax..
SELECT *
FROM employees
LIMIT 10,10;
..but it didn't seem to work.
Thanks for any help!!
Row_number Selecting From A Complex Select Statement
Sep 3, 2007Hi,
Code Snippet
This is difficult to explain in words, but the following code outlines what I am trying to do:
with myTableWithRowNum as
(
select 'row' = row_number() over (order by insertdate desc), myValue
from
(
select table1Id As myValue from myTable1
union
select table2Id As myValue from myTable2
)
)
select * from myTableWithRowNum
Can anyone think of a work around so that I can use the Row_Number function where the data is coming from a union?
Selecting The Most Recently Edited Item AND Selecting A Certain Type If Another Doesn't Exist
Sep 20, 2007I've got a big problem that I'm trying to figure out:
I have an address table out-of-which I am trying to select mailing addresses for companies UNLESS a mailing address doesn't exist; then I want to select the physical addresses for that company. If I get multiple mailing or physical addresses returned I only want the most recently edited out of those.
I don't need this for an individual ID select, I need it applied to every record from the table.
My address table has some columns that look like:
[AddressID] [int]
[LocationID] [int]
[Type] [nvarchar](10)
[Address] [varchar](50)
[City] [varchar](50)
[State] [char](2)
[Zip] [varchar](5)
[AddDate] [datetime]
[EditDate] [datetime]
AddressID is a primary-key non-null column to the address table and the LocationID is a foreign key value from a seperate Companies table.
So there will be multiple addresses to one LocationID, but each address will have it's own AddressID.
How can I do this efficiently with perfomance in mind???
Thank you in advance for any and all replies...
Selecting A View And Selecting FROM A View Is Wildly Different
Feb 21, 2006A colleague of mine has a view that returns approx 100000 rows in about 60 seconds.
He wants to use the data returned from that view in an OLE DB Source component.
When he selects the view from the drop-down list of available tables then SSIS seems to hang without any data being returned (he waited for about 15 mins).
He then changed the OLE DB Source component to use a SQL statement and the SQL statement was: SELECT * FROM <viewname>
In this instance all the data was returned in approx 60 seconds (as expected).
This makes no sense. One would think that selecting a view from the drop-down and doing a SELECT *... from that view would be exactly the same. Evidently that isn't the case.
Can anyone explain why?
Thanks

Multiple Tables Used In Select Statement Makes My Update Statement Not Work?
Aug 29, 2006I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

View 1 Replies View RelatedDo While Skip In Selecting...
Oct 21, 2004Hello:
I have one table and it contains a column named ID Number, and a column named Date. I have a Do While statement that runs a SQL select statement a few times based on the number of records with the same ID Number. During the Do While statement the information is copied into another table and deleted from the old table. After I look at the results, I see that at the second Do While loop, the data was not selected and the Select statement did not run... so the old variable value from varValue is used again... Any reasons on why?
Here is a code snippet of what is going on:
Do While varCount < varRecordCount
conSqlConnect.Open()
cmdSelect = New SqlCommand ("Select * From temp_records_1 where [id number]=@idnumber and date<@date", conSqlConnect)

Selecting * WHILE Converting
Jun 2, 2005I have a tbale with maybe 30 columns and I'm selecting all where a
record number matches a parameter I've passed. That works fine,
however is there any way to do some conversions to fields when
selecting without having to list out each column? For instance
this is what it looks like now:
SELECT *
FROM Losses
WHERE @AppRecord = AppRecord
ORDER BY Record ASC
But I want to convert say one column, is there a way to keep similar syntax instead of listing out each column?
SELECT *, CONVERT(varchar(15), [Losses]) as [Losses]
FROM Losses
WHERE @AppRecord = AppRecord
ORDER BY Record ASC
And the column I'm converting is of type 'money'. I'm converting
it to get rid of the extra zeroes at the end. If you know a
better way to do it I'd be interested in knowing.

Sep 20, 2005Hi
I have a content management system that I am building. My CMS has a
pages table which contains 60 fields, some are varchars, some are ntext
some are dates etc. They have field names which match their purpose
like varchar1, ntext3 etc. These fields are used up depending on which
template is applied to the page.
The templatefields table holds holds the information about each field
in a template. It's control type (rich text control, date control etc)
and the field in the pages table that the data will be stored in
(varchar1,ntext3 etc)
What I want to be able to do is loop through the templatefeilds table
for a particular template and then using the field name for the pages
table, go to the pages table and get the value to populate the control.
So to clarify, I would like to produce a stored procedure which outputs
the page field name (varchar1) from the templatefields table and
varchar1's value in the pages table. Maybe in a temporary table.
Is this possible?
Any guidance would be appreciated..

Selecting Indexes
May 8, 2001We are developing an Access application that will be used to run adhoc reports against a SQL Server table. Selection criteria is entered on a form, a passthru query is built on the fly, and the results are formatted for output via an Access report.
There are 16 different fields on the query form. Two are date fields (from / to), the rest are text. The user is required to supply a date range for the report. They may specify any combination of the remaining query fields.
Examples:
From/To dates, part number, work order number
From/To dates, location, operation, sales order number, operator
What is the best scheme to use for the indexes? One index for each potential query field? Or, a single index that includes ALL query fields? Or, some other combination?
I should also mention that there will be no realtime updates to the table. On a weekly basis, we will import updates from a mainframe extract (dropping the indexes prior to the import, rebuilding them afterwards).
