Hello,
How can I stop/prevent SQL server from running compound SQL
statements. I do not want the server to run multiple
update/delete/insert/select statements as a batch. Is there an option?

I need to know how to create a compound primary key in Transact-SQL
It's really simple, it's a table with 3 column, two of those make the primary key Right now the CREATE TABLE look like this:/* SectionsContent Table */
CREATE TABLE SectionsContent (
SectionID Int NOT NULL
CONSTRAINT FK_SectionsContent_SectionID FOREIGN KEY
REFERENCES PsychoCMS.dbo.Sections(ID),
DocumentID Int NOT NULL
CONSTRAINT FK_SectionsContent_DocumentID FOREIGN KEY
REFERENCES PsychoCMS.dbo.Documents(ID),
Position int NOT NULL
)
Can anyone help me ?
Is it possible to force the use of a compound index in a query?create table Test (ColOne int, ColTwo int)The compound index is ColOne + ColTwo.I'm interested in searching on ColTwo, but I also know the value ofColOne will always be the number "1".How do you structure the SQL statement to concatenate the two INTs anduse the index? Note that I don't have any control over the creation ofthese indexes.

I want to add a return column that is not in the table, and the table columns:
something like
Select @Ten As Ten, @Tablename.* From @Tablename (
where @Ten has an integer value. )
The statement was originally:
select @SQL = 'select * from ' + @TempName
exec (@SQL)
which had no problem. Then I needed to add an extra column of static data to all the returned rows, and confusion !!!!!

BEGINNER QUESTIONI have a table which has a compound primary key consisting of two columns.One of these columns is a foreign key which is generated in another table byan identity.I want to be able to generate the other primary key column valueautomatically when an insert occurs but assume that I cannot use an identitybecause it would have to be unique for this table.There will be potentially more than one user accessing this table so I wantto avoid generating the key on the client side.How can I do this? Will it require some hardcore T-SQL?I hope this is clear (I suspect it isn't) I'd be happy to supply more info.I would be extremely grateful for any help!Mark.

The problem is with this column:
(lag(daily_return, 1, 0) over (order by date1) + 1) * (daily_return + 1) - 1 as Compound_return
The (daily_return + 1) portion should be the accumulated compound return. So it should be something like
(lag(ACCUMULATED_COMPOUND RETURN, 1, 0) over (order by date1) + 1) * (daily_return + 1) - 1 as Compound_return
And the output should be:

Hi
I have a sql 2000 db which has a table that has a compound key, the problem is that I would like to create a Full Text Catalog for this table. However I noticed that i need a single primary key... but I dont have one.
I created another field on my table called "ftcID" as an int with identity set to Yes
However when I try and create a catalog it doesnt detect that this field is unique.
Does my unique field have to be a Primary Key, I cant remove the compound primary key as it will break my application.
Any help would be much appreciated
Many thanks in advance
Hi all,
I've had this problem for a while now and I'm looking for a better solution.
I'm pulling through a dataset from a SQL Server 2005 database and populating it into a DataGridView. The end user updates information on the grid and I then want to updates the results in the SQL Server table. My table has a compound primary key made up of two fields.
I'm currently looping through the data grid and for each value identified to update I'm executing a stored procedure that takes the two fields as parameters. However I know that this method isn't very efficient, especially if the user wants to update a few hundred records as it will execute the stored procedure a few hundred times.
Is there a way I can pass the two parameters in an ArrayList or something like that? I need SQL Server to be able to take the parameter. Is XML the way to go or is there any additional support in the .NET framework for such problems?
Thanks for your help.
Hai,
I have been working in DW for a while, but using SSIS as an ETL tool is new for me. I worked extensively on Informatica.
Coming to my question, right now I am trying to do SCD type 1. But my dimension table has a compound key. i.e more than 1 column makes a key for the table. But SCD wizard allows to select only 1 attribute as a business key. Does any one have any suggestions on how to implement SCD if the target table has compound key.
Thanks in advance for your suggestions and answers.

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?

Hi, i just want to know if the T-SQL statements in SQL server 2005 are different from SQL Server 2000???

Hello,
I have a report with 1 field that I need to sum into 2 different textboxes based on another field's value.
Specifically, Is it simply doing something like this below?
=Iif(Fields!iBB.Value=1, Sum(Fields!Billed.Value)
=Iif(Fields!iBB.Value=0, Sum(Fields!UnBilled.Value)
Which will not get past intellisense checking, -or- do I have to do something different here?
Thanks in advance.
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)

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')

Hey everyone,
I'm making a site and I need to write some code that will do the following things:
Write a statement for the Page_Load event to pull the information from the db and load it into a textbox and a textbox with multiline attribute.
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.
Thanks,

Folks,
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.

Hi,
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')

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.
