I am building a website with VS2005Standard. Onto an empty aspx page I drag a SqlDataSource control. In the "Configure datasource" dialogs I connect it with the SQL database file of my web app. In the "Configure the SQL statement" tab I select "*" for the columns and open the "advanced" dialog (I don't know the exact english terms because I use the german version) because I want to create INSERT, UPDATE AND DELETE statements separately. BUT: the upper checkbox (i.e. both checkboxes) is disabled! What can I do the get it enabled.
I have created a stored procedure with multiple select statements using MSSQL 2000. When I connect to this using a SQLDataSource it only seems to get the first SELECT. I need to access the multiple tables returned by the stoped procedure. Can anyone point me in the dirrection of how to do this.ThanksClearz
Although writing a parameterized SQL statement has been simplified using the asp:parameter options, it still may benefit to use the old fashioned method of writing a sql statement using an input string. I have noticed this for wanting to make a parameter to select which table I want to pull from. Here is some code I wrote to pull information from a database based on input from a search box and write it to a gridview. Partial Class Private_SearchResultsInherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim Table As String Dim SearchString As StringSearchString = Request.QueryString("SearchString") Table = Request.QueryString("Table") If Len(Trim(SearchString)) > 0 ThenSelect Case Table Case "Plant" SqlDataSource1.SelectCommand = "SELECT PlantName as 'Plant',PlantAddr as 'Address',PlantCity as 'City',PlantState as 'State',PlantCountry as 'Country',PlantZip as 'ZIP' FROM Plant WHERE PlantName LIKE '%" & SearchString & "%' OR PlantCity LIKE '%" & SearchString & "%' OR PlantState LIKE '%" & SearchString & "%' OR PlantCountry LIKE '%" & SearchString & "%' OR PlantZip LIKE '%" & SearchString & "%' ORDER BY PlantName" Case "Contacts" SqlDataSource1.SelectCommand = "SELECT ContactPosition as'Position',ContactTitle as 'Title',ContactLast as 'Last Name',ContactFirst as 'First Name',ContactPhone as 'Phone No' FROM Contacts WHERE ContactLast LIKE '%" & SearchString & "%' OR ContactFirst LIKE '%" & SearchString & "%' OR ContactPosition LIKE '%" & SearchString & "%' OR ContactPhone LIKE '%" & SearchString & "%' OR ContactTitle LIKE '%" & SearchString & "%' ORDER BY ContactLast" Case "Events" SqlDataSource1.SelectCommand = "SELECT EventName as 'Event',CONVERT(varchar,EventStartDate,101) as'Start Date',CONVERT(varchar,EventEndDate,101) as 'End Date',EventNotes as 'Notes',EventNoAttendees as 'Attendees',EventType as 'Event Type' FROM Events WHERE EventName LIKE '%" & SearchString & "%' OR EventStartDate LIKE '%" & SearchString & "%' OR EventEndDate LIKE '%" & SearchString & "%' OR EventNotes LIKE '%" & SearchString & "%' OR EventNoAttendees LIKE '%" & SearchString & "%' OR EventType LIKE '%" & SearchString & "%' ORDER BY EventName" Case "" Label1.Text = "Nothing Selected in Drop Down Box" End Select Else Label1.Text = "No Search Parameters Entered" End If GridView1.DataBind()End Sub End Class
Here is also my code to the front end of the page...
Hi,I'm new to ASP.NET and having a problem configuring the SqlDataSource control. I am using the standard ASP.NET 2.0 "aspnetdb" database to manage user accounts. The problem is this:When using the wizard to configure my SqlDataSource control, the option to auto-generate the Insert/Update/Delete SQL statements are grayed out. I've searched this forum and found that this can be a symptom of no primary keys in the tables. However, there are primary keys (UserId), which is the default schema as generated by asp.net (aspnet_regsql.exe). When I use the wizard, I make the following choices:How would you like to retrieve data from your database?-> Select "Specify columns from a table or view"-> Select the "vw_aspnet_MembershipUsers" view from the "Name:" drop-down list-> Select "UserId", "Email", "UserName" from "Columns:"After this, still no option to auto-generate I/U/D statements. Any thoughts on why this isn't working??? Thanks,Leah.
What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
i am using visual web developer 2005 with SQL Express 2005 with VB as the code behindi have one database and three tables in itfor manipulating each table i am using separate SqlDataSource() is it sufficient to use one SqlDataSource() for manipulating all the three tables ? i am manipulating all the tables in the same page only please help me

I use SQL Server 2005.I want to create a SP "Search". With this function a user can serach the member database on several criteria: age minimal, age maximal, name, city..BUT these criteria do not necessarily have to be defined by the user, so it might be that a user searches for all members whose age is between ageMin and ageMax leaving the name and city criteria empty.So in my SP I have to check whether these values are empty or not. If a parameter is not empty I have to add it to my selection query.. BUT, I know that SQL Server makes an execution plan, and understood that when you use if-statements the procedure needs to be recompiled every time?Is this true? If so:how does this work then?Is there another way for me to still be able to create this SP?
Hello guys. How is this declared in SQL? Select * FROM my_table if my_column = "1" UPDATE my_table SET my_other_column= "a" ////my_column and my_other_column belong to my_table else if my_column="2" UPDATE my_table SET my_other_column= "b" ////my_column and my_other_column belong to my_table

I need to create a brief statement in Design View for SQL 2000.
I successfully wrote "isnull(dbo.Data.Parcel,'')in the Column in Design View, which would ensure that a null value would be listed as a blank. Now I need to have dbo.data.status show as 'C&G' in any instance of data, otherwise it will be listed as blank. I tried writing "isnotnull(db0.data.status,'Homestead', '')", but it does not work.
Is there a simple statement I can write in "column" of design view that can get the results that I need?
I have written an sql statement thats using sum. The problem that I have is that when the value is zero it returns Null. Is there a way that I could return zero instead of null.
I am totally new to creating IF statements inside stored procedures. I am passing some parameters from a ColdFusion form to a SP and if the form is empty for the small date I get an error. I would like to be able to check in the procedure to see if the parameter is empty and if it is set a default value for it. Here is my code. @JOB1, @COLLEGEDATE smalldatetime, If(@COLLEGEDATE <> ''") @COLLEGEDATE smalldatetime, ELSE @COLLEGEDATE = getDate(), RETURN @JOB2
Hi guys! I have these commands that insert into two tables, if condition 1 is met, it will insert into the first table, if the second condition is met, it will insert into the second table. Is there a way for the insert statements to be merged so that I won't be executing two statements? Dim update_phase_before As New SqlCommand("INSERT INTO TE_shounin_todokesho_jizen (syain_No,date_kyou,time_kyou) SELECT syain_No,date_kyou,time_kyou FROM TE_todokesho WHERE TE_todokesho.b_a='before'", cnn) Dim update_phase_after As New SqlCommand("INSERT INTO TE_shounin_todokesho_jigo (syain_No,date_kyou,time_kyou) SELECT syain_No,date_kyou,time_kyou FROM TE_todokesho WHERE TE_todokesho.b_a='after'", cnn)
Hello, how can i merge together several select statements?

I'm running a custom built report on .net page Basically there are a lot categories. I need to run SQL statements for and for each category, the catch is these statements are all in loops for i = 1 to 12. Therefore 108 categories X 12 iterations of SQL calls = a little more that 1200 sql calls from one .net page. There is obviously a major problem with load time and running these reports are painful to the user and the system.
Is there any easier way to possibly pre-compile all the data into a temp database so I wouldn't need to make as many sql calls??????? If so, would a stored procedure handle something like this. Sorry for being somewhat vague.
How do I handle and apostrophes and other punctuation in stored procedure Sql statements: SELECT L_ID, L_NameFROM tblHVACContractorsWHERE (L_Name = 'Mare's Heating & Cooling Services')
I'm trying to combine the following two strings to create a single Insert statement (and thus only generate one record instead of two). insertString = "Insert comments (uID) Select uID FROM users WHERE uName = @uName" insertString2 = "INSERT comments (eventID, text) VALUES ( @eventID, @comment)" I have tried: Insert comments (uID, eventID, text) SELECT uID FROM users WHERE uName = @uName VALUES (uID, @eventID, @comment) Individually they work fine, but I can't get the syntax correct to allow them to work together. As you can tell, I'm not very good with SQL, so any help would be greatly appreciated! Thanks in advance.
I have a web application that has SQL7 as the back end. SQLServer and ORACLE have a feature that allows sql commands to be combined in one statement. Another words I am able to to
SELECT * FROM table_name WHERE id = 2 DROP TABLE other_table
If I type this in a query analyzer It will perform both commands. Is there a way to turn this 'feature' off.
The main reason I want to turn it off is so if a numerical value is sent as a url variable someone can't add the drop table statement or any other sql command to the value of the url variable and have it executed. We have added ample code to trap for this problem but I would like to also handle it at the database level.
I'm having some real problems using the OR condition in a very simple SQL statement and could use your help or insight on where the problem lies, or perhaps a workaround.
I have a large flat table in a SQL 7 database with 10 million + records called "HISTORY". I have not installed either service pack 1 or 2. I'm attempting to run a query that references the following four fields which are all non-clustered keys:
EQUIPMENT_NO TEXT 12 CHASSIS_IN TEXT 12 CHASSIS TEXT 12 SVC_DATE_TIME SMALLDATETIME
Here's the SQL statement:
SELECT * FROM HISTORY WHERE (HISTORY.EQUIPMENT_NO = 'XYZ123' OR HISTORY.CHASSIS = 'XYZ123' OR HISTORY.CHASSIS_IN = 'XYZ123') AND SVC_DATE_TIME >= '01/15/00 00:00:00 AM' AND SVC_DATE_TIME <= '02/28/00 23:59:59 PM' ORDER BY EQUIPMENT_NO
This query takes 11 min. 5 sec. inder the Query Analyzer and ultimately returns the 31 desired records.
If you remove the SVC_DATE_TIME criteria, about 350 records are returned in a matter of seconds. I've also tried variations on the date syntax such as '01/15/00', etc. with no change in the amount of time to execute.
Other queries such as a simple AND condition combining EQUIPMENT_NO and SVC_DATE_TIME are snappy.
Are there known problems/bugs with "OR" conditions in queries that anyone is aware of, particularly with parentheses; am I composing this query incorrectly? Is there some alternate syntax that would work as expected? I can't see where the query shouldn't execute quickly as expected, particularly with all indexed fields involved. I'm stumped! Lend me your expertise. Thanks much.

I am having some problems trying to build an sql statement from more than one statement.
Here is the statement
select 'Insert App_Column (Table_ID, Column_Type_Transformation, Column_Name, ) Values (@table_ID,' ,'NULL,', name from payatwork..syscolumns where id in ( select id from payatwork..sysobjects where name like 'Employee_Profile') order by colorder, ')'
What I am finding is that the bracket at the end of the statement is not appearing - how do I append statements to the end of this sql statement (i've tried various combinations of the + sign and the comma without success.
I have a web application that has SQL7 as the back end. SQLServer and ORACLE have a feature that allows sql commands to be combined in one statement. Another words I am able to to
SELECT * FROM table_name WHERE id = 2 DROP TABLE other_table

I have 2 piece of code designed to do the same thing. My problem is, i'm not getting the same results.
Code 1 where the results are correct
Code:
select Count(*) as TotalCount, Sum(DistAmt) as TotalSum from table1 inner join table2 on table2.id = table1.id where MailTypeID = 3 AND MailEventID = 2 and table1.IsActive = 1
code 2 - Y is correct, but Z is not, and not only is it not correct, but it is returning a number which equals more then the total rows from the table.
Code:
select Y = sum(case when mailtypeid = 3 and maileventid = 2 and IsActive = 1 then distamt else 0 end), Z = count(case when mailtypeid = 3 and maileventid = 2 and IsActive = 1 then 1 else 0 end) from table1 inner join table2 on table2.id = table1.id
Is there a way to use more criteria in a CASE statement other than CASE WHEN expression THEN value ELSE value END
I need to test if the count is greater than 0. If so, then perform the case statement, else return zeros. Currently there are entries where the values are blank. These blank values are causing errors in the application and unfortunately, I am not able to update these values.
So far I have the following, but I am getting an error stating "An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or select list, and the column being aggregated is an outer reference."
Thanks in advance!
Code:
IF @Qid = 4 SELECT @Exp as Status, COUNT(*) AS Total, @CourseID as CourseID,
(SELECT question FROM tableQuestions WHERE qid = @Qid) AS Question,
IF COUNT(*)>0 THEN
1.0 * SUM(CASE WHEN A.Q1 > 1 THEN 1 ELSE 0 END) / COUNT(*) AS Positive, 1.0 * SUM(CASE WHEN A.Q1 = 0 THEN 1 ELSE 0 END) / COUNT(*) AS Neutral, 1.0 * SUM(CASE WHEN A.Q1 < 0 THEN 1 ELSE 0 END) / COUNT(*) AS Negative, 1.0 * SUM(CASE WHEN A.Q1 = 0 THEN 1 ELSE 0 END) / COUNT(*) AS NA ELSE 0 AS Positive, 0 AS Neutral, 0 AS Negative, 0 AS NA
END IF
FROM table1 A INNER JOIN table2 B ON A.SessionID = B.SessionID
WHERE (B.CourseID = @CourseID) AND (A.SubmitDate >= @BeginDate) AND (A.SubmitDate <=@EndDate)
Im trying to get some of my queries to run a little faster and i think i have an idea on how but i cant seem to get my and IF statements to work
basically what i want is for the different parts of my WHERE clause to run only if certain variables have a value. so something like this
Code:
SELECT * FROM tablename WHERE
IF LEN(@color) > 0 BEGIN color = '@color' END
IF LEN(@size) > 0 BEGIN AND size = '@size' END
so i only want it to limit it by color if @color has a length of more than 0. if there is a better way to do this (other than IF statments) then please let me know.
Im just getting an error saying incorrect syntax near IF
