How To Form SQL Select Queries Using Drop Down Lists??

Nov 8, 2006

Hi

 Will somebody please explain how  to combine asp.net dropdown lists to write

a  SQL database select query. I am using VWdeveloper and C Sharp.

For example, say I have  3 dropdownlists on my  webpage  as below,

List 1, Cities, London, Rome,  Barcelona etc

List 2, Restaurants by  Type, Italian, chinese, Indian etc

List 3, Number of tables/ seats 10-20,  20- 40, 50  -100

I want someone to be able to  search for a restaurant by selecting  an  item from  each dropdownlist

such as, "Barcelona" "Italian" "50-100"

This search query would return all the Italian restaurants in Barcelona with  50-100  tables/seats.

I  would also like the select query to work even if one of the dropdownlists items  is not selected.

Hope  somebody can clear this up?

Also would sql injection attacks be a threat by doing it this way?

Thanks all

Drop Down Lists

May 27, 2004

I'm want to be able to choose(including multiple selections) names from a drop down list that are fetched from the database(from table "Employees") and add them to table "Biotechnology".

Employees(ID,FirstName,LastName)
Biotechnology(ID,EmployeeID)

**assuming that EmployeeID in "Biotechnology" is the ID from "Employees" table

Example: We add Employees.ID(23, 33) to Biotechnology.EmployeeID

would be

Biotechnology:
[ID] [EmployeeID]
01 - 23
02 - 33

Creating A Form With A Drop Down List Of The Foreign Key Values

Jun 19, 2002

I have the following tables in an SQL Server database.

Contact
=======
NameID
TitleID
Name

JobTitle
========
TitleID
Title

I'm trying to make a form to add entries to the Contact table that lets me associate a job title to a name by choosing it from a drop down list. I have been able to make it so I get a drop down list of TitleID but I need the Title field displayed. I haven't been able to do it. Does anyone have any tips on how to do this?

(Select All) In Multi-select Enabled Drop Down Parameters Doesn't Work

Apr 29, 2008

Hello all,
I have two mult-value parameters in my report. Both of them working with selecting one or more values. But, when I test using "(Select All)" values for both parameters , only one parameter works. The "available values" for these two parameters are both from the data set.

select distinct ProductType
from Product
order by ProductType

Any suggestion? thx

(Select All) In Multi-select Enabled Drop Down Parameters

Feb 27, 2008

There are several parameters on a report. One of the parameter is a multi-select enabled parameter and I suppressed the value "All" showing as one of the item in the drop down list, simply by filter out the [bha].[bha].CURRENTMEMBER.LEVEL.ORDINAL to 1, as "(Select All)" is pre-assigned to the drop list when multi-select is enabled and it is confusing to show "(Select All)" and "All" in the drop list. However I have another report which is linked to this report and the value which is required to pass to this report for this parameter is "All". Can I pass the "Select All" as a parameter from the other report? If so, how? Thanks.

Two Select Statements In SP Return No Value In Web Form (only)

Mar 29, 2008

Hello. I  a SP with 2 select statements. If the first returns no results it does the second select. This works fine if I test it on the sql server. But when I try it in a webform using a sqldatasource it only returns a result if the first Select returns rows. If not It is an empty set (where I know it should not be. It returned resultrs on the SQL server). This is the code:1 ALTER PROCEDURE [SPName]
2
3 @SearchFor varchar(150) -- search string to compare with
4
5 AS
6
7 SELECT p.UserName,
8
9 (Select ImageName from ProfileImages Where IsMainImage = 1 And ProfileID = p.ProfileID) as ImageName,
10
11 (SELECT COUNT(*) FROM auditions WHERE UserID = p.ProfileID) AS AuditionCount
12
13 FROM Profiles p WHERE UserName = @SearchFor
14
15 IF (@@ROWCOUNT = 0)
16
17 Begin
18
19 SELECT p.UserName,
20
21 (Select ImageName from ProfileImages Where IsMainImage = 1 And ProfileID = p.ProfileID) as ImageName,
22
23 (SELECT COUNT(*) FROM auditions WHERE UserID = p.ProfileID) AS AuditionCount,
24
25 DIFFERENCE(p.UserName, @SearchFor) as Similarity
26
27 FROM profiles p WHERE SOUNDEX(p.UserName) = SOUNDEX( @SearchFor )
28
29 ORDER BY Similarity
30
31 END
32
33 RETURN
Now If i change the SP to test it to the code below, it does work in  both the webform and on the sql server: 1 ALTER PROCEDURE [SPName]
2
3 @SearchFor varchar(150) -- search string to compare with
4
5 AS
6
7 DECLARE @RowCount int
8 SET @RowCount = 0
9
10 IF (@ROWCOUNT = 0)
11
12 Begin
13
14 SELECT p.UserName,
15
16 (Select ImageName from ProfileImages Where IsMainImage = 1 And ProfileID = p.ProfileID) as ImageName,
17
18 (SELECT COUNT(*) FROM auditions WHERE UserID = p.ProfileID) AS AuditionCount,
19
20 DIFFERENCE(p.UserName, @SearchFor) as Similarity
21
22 FROM profiles p WHERE SOUNDEX(p.UserName) = SOUNDEX( @SearchFor )
23
24 ORDER BY Similarity
25
26 END
27
28 RETURNOnce again, Everything works as it should (for both versions), if I am testing it directly on the SQL server. Can anyone Help me on this? I am stumped and cannot find any answers about this.

Drop Table Select Into

Jan 28, 2008

I'm confused as to how this sp is working? Can you drop a table and then select into it without recreating it? I thought when you dropped a table it was gone.

sp:
drop table tmp_claimeligiblebalance

SELECT tsd_Claim.clpid,
Sum(tsd_Claim.cloutstandingamt) as sumoutstanding
INTO tmp_ClaimEligibleBalance

FROM tsd_Claim

GROUP BY tsd_Claim.clpid
HAVING sum(tsd_Claim.cloutstandingamt) <>0 AND sum(tsd_Claim.cloutstandingamt) IS NOT NULL
And max(tsd_Claim.clfromdos) < (cast(getdate() as smalldatetime) - 120) And max(tsd_Claim.clins) Is Not Null

DROP TABLE, SELECT INTO, Performance

Jul 11, 2007

Hello -- thank you for taking the time to read this.

I have a very large table that is used both for archives and new information. To get the current information, the table is queried by many different users at various polling periods. The SELECT required includes about fifteen JOINS, and only returns about 200 rows at any given time.

So I got to thinking if it might be faster to periodically run the big query as a SELECT INTO into a smaller table and letting the polling clients query the smaller table with SELECT *. Periodically, the smaller table would be DROPPED and refereshed with another SELECT INTO.

Trouble is, the data would have to be updated once every 30 seconds, and there are inbound polls coming at the rate of about 200 per minute. It got me to thinking what might happen if a client attemtped to query the smaller table when it was in the process of being dropped and refilled.

So my question is three-part:

1) assuming a larger table of about 500,000 records and only 500 pertinent at any given time, is there any real potential of performance enhancement by switching to a SELECT INTO table?

2) if so, is there a chance of a client failing a query if the inbound query somehow collides with the DROP/SELECT INTO procedure?

3) if so, is there any way to prevent it or a better way of doing this?

Thanks again for reading, and in advance for any help you can provide. I apologize if I sound like a dummy - it's hard to fake intelligence!

SELECT TOP N Queries In SQL 7

Jul 28, 1999

I'm having problems executing TOP n queries on a database that was migrated from 6.5 to 7. I can get it to work on the Authors table in pubs, not in my other dbs. Here is an example:

CREATE TABLE dbo.tblsapParentCust (
Parent char (10) NOT NULL ,
Name varchar (40) NULL,
IsSoldTo bit NOT NULL DEFAULT 0,
CONSTRAINT PK_tblsapParentCust PRIMARY KEY CLUSTERED
(Parent)
)
GO

<load in some data>

SELECT TOP 10 * FROM tblsapParentCust

The select statement results in a syntax error:

Server: Msg 170, Level 15, State 1, Line 1
Line 1: Incorrect syntax near '10'.


I can switch over to pubs and change the query to reference the Authors table, and it runs fine.

If anyone can explain this behavior to me, I would appreciate it.

Thanks,
Buddy

One Form To Update Different SQL Tables Based Upon Form Selection

Apr 16, 2008

Hello,
My company Intranet has a form that agents can use to post their comments about the company to upper management, but our customer service department would like to modify the form so that the agent has to pick from a comment type.
The dropdown options on the form will be as follows:
ComplimentsComplaintsGeneral CommentsSuggestions
Each dropdown option has a designated table in a SQL DB.Using postback on the same page, I need to change which fields of the form are visible based upon which dropdown selection the user chooses, and I need the fields to then be inserted into the table that corresponds with the dropdown selection item.
For example: If the Compliments dropdown selection is picked, I need a text box to show for the user's location, the name of the customer, account number, and the message box. Once the submit button is clicked, the characters in these boxes need to be inserted into the Compliments table using its data adapter.
However, if the user selects Suggestions, the name of the customer and the account number should not be visible, since these fields do not exist and when the submit button is pressed, the Suggestions table should be updated.
If you need more information, I will provide whatever is needed.
As always, thanks for everyone's assistance.
Chris

The select query is like :

Can I Write Multiple 'Select' Queries In Access? Please Help!

Jul 22, 2004

I'm trying to code a query in Access that finds rows w/ duplicate "ContactKeys" then finds duplicate "AddressLine1s" out of the list of duplicate "ContactKeys." (I tried subqueries but it was really slow)

I am trying to create a new table with only duplicate ContactKey rows, and then I wanted to use that table to pick out the duplicate AddressLine1 rows.


Code:


SELECT *
INTO dupContactKeys
FROM Contacts
WHERE ContactKey IN (
SELECT ContactKey
FROM Contacts
GROUP BY ContactKey
HAVING COUNT(*) > 1)

SELECT *
FROM dupContactKeys
WHERE ContactKey IN (
SELECT AddressLine1, Zip
FROM Contacts
GROUP BY AddressLine1, Zip
HAVING COUNT(*) > 1)
ORDER BY ContactKey, TypeKey;

drop table dupContactKeys



This of course doesn't work. Please help, as I am going slightly mad!

How Can I Do Amalgamate 3 Select Queries And Then Get Unique Entries From The Result

Hi AllStrange request I know, but could somebody give me pointers on how I can put3 queries into 1 'thing' and then get only the unique entries from this'thing'.To explain, I'm using Excel/VBA/ODBC to query an SQL DB. The 3 queriesthemselves aren't that complex and all return the same 2 fieldsets of stockcode and stock desc. Because these separate queries might bring back thesame stock code/description I need to amalgamate the data and then queryagain to bring out only distinct stock values, eg:Query 1 brings back:stock code stock descIVP Invoice PaperSTP Statement PaperKGC Keyboard Coveretc... etc...Query 2 brings back:stock code stock descIVP Invoice PaperBOB Back PackKGC Keyboard Coveretc... etc...Query 3 brings back:stock code stock descKGC Keyboard Cover3.5"D 3.5" Disksetc... etc...I need to produce 1 resultset that shows:stock code stock descIVP Invoice PaperBOB Back Pack3.5"D 3.5" DisksKGC Keyboard CoverSTP Statement Paperetc... etc...(all unique entries)I'm currently just bringing back the 3 query results in Excel, but I'd liketo be able to do the above.In light of I'm using Excel/VBA/ODBC on a PC, is it possible to do?ThanksRobbie

But on the back end sql server, if i execute the same stored proc, i get 4 resultsets in one single executioln.

i am not seeing the remaingin 3 resultsets, on the reports dataset.

Is it possible on the reports or not.

In the asp.net project i was able to use that kind of stored procedures whcih has multiple select statements in 1 procedure., i use to refer 0,1,2,3 tables under a dataset.

Thank you all very much for the information.

Parameter Information Cannot Be Derived From SQL Statements With Sub-select Queries

Apr 24, 2006

Parameter Information cannot be derived from  SQL statements with sub-select queries. Set Parameter information before preparing command.

Here's the query:

update GCDE_SEQ
set LAST_NO =  (select  max(FLD_NO)
   from PONL_FLD)
 ,UPDT_USER = ?
 ,UPDT_DT = getdate()
where SEQ_NM = 'FLD_NO'

Why can't Execute SQL Task handle this simple query? I figure i can use 2 SQL Execute SQL Task, one to get the max into a var, and the other to do the updating. However, this is alot of trouble since i'm having this almost exact query in alot of places. Any way around this?
