Storing Results Of Select Statement In @variable
I'm new to sql stored procedures but I would like to store the results
of an sql statement in a variable such as:
SET @value = select max(price) from product
but this does not work, can someone tell me how I would go
about in storing the results in a variable.
@value is declared as int
Thanks in advance,

Update Statement Using Declared Variable Produces Unexpected Results On SQL Server 2005
We are getting unexpected results from the following update statement when it is executed on SQL Server 2005. The strange thing is that we get duplicated values for QM_UID (although when run under SQL Server 2000 we don't get duplicated values) Can anyone explain why this happens or suggest another way of populating this column without using a cursor or adding a temporary autoincrement column and copying the values over? declare @NextID int; set @NextID = 1; update tmp set QM_UID=@NextID, @NextID = @NextID + 1; select QM_UID, count(*) from tmp group by QM_UID having count(*) > 1 order by QM_UID QM_UID count(*) 25 2 26 3 27 4 28 4 29 4 30 4 31 4 32 4 33 4 34 4 35 5 36 4 37 4 38 4 39 4 40 3 ...

Invalid Results For Order By On Select Query Against Table Variable
I am attempting to sort the results of a query executed against a table variable in descending order.

Cycling Through Results Of A Select Statement
I am new to stored procedures and T-SQL so please stick with me. I have a table that holds information about companies. I am trying to write a stored procedure that when run will query that table and find out if there are more than one entry of that company. All company names in that table must be unique (they can only occur once), if they occur more than once I need to flag it for reporting. So what is the best way to go about this? Essentially what i was thinking was doing a select * on the table and then going from the first entry to the last and at each entry running a select * from table where companyname = @nameofcompany. @nameofcompany would be the name for that entry. If the select statement revealed more than one entry then i would know there was a problem. Like I said I am new and this is probably very simple but i need a little help getting started thanks

Count # Of Results From SELECT Statement
Hey all - VERY new to SQL so I apologize if I butcher normally trivial things :) Looking to run a query that will retrieve the number of results returned from a select statement... Currently have a LicenseID table with a Software column...the statement that works on it's own that i've got is: SELECT * FROM Software WHERE LicensesID = 2 Currently when I run that with the data so far I get 4 results returned to me...how can I add to that statement so that instead of displaying the results themselves, I just get the number 4 returned as a total number of results?

SELECT Statement Not Giving Me Desired Results
I have the following SELECT statement attached to a dropdown box: SELECT [Workshop] FROM [Workshops] WHERE Workshop <> (SELECT Workshop FROM Workshop_Registration WHERE FullName = @FullName AND Completed = @Completed) ORDER BY [Workshop] I am trying to get all workshops (50 or more) from the WORKSHOPS table that the logged in user is not already registered for. This works perfectly as long as the student is registered for at least 1 class. It populates the dropdown with all of the other classes. If they aren't registered for a class then it doesn't list any classes. The problem is definitely the subquery, but how do I make it to where if the subquery doesn't return any results (student not registered for anything), I get all of the workshops in the dropdown? Any help is appreciated! MikeD

Excluding Part Of Select Statement If No Data Is Returned In Results
I have a query that returns results based on information in several tables. The problem I am having is that is there are no records in the one table it doesn't return any information at all. This table may not have any information initially for the employees so I need to show results whether or not there is anything in this one table. Here is my select statement: SELECT employee.emp_id, DATEDIFF(mm, employee.emp_begin_accrual, GETDATE()) * employee.emp_accrual_rate - (SELECT SUM(request_duration) AS daystaken FROM request) AS daysleft, employee.emp_lname + ', ' + employee.emp_fname + ' ' + employee.emp_minitial + '.'

Any help would be greatly appreciated!!! TIA

SQL Select Statement With A 'string' Variable?
I'm trying to add a 'change password' control to my site and seem to be having some issues. I have code that works if I statically define what user is displayed on the form, but I cant get it to detect the 'authenticated' user and show them the reset for for that ID.If I take the "+ myid" out of the select statement and just define the username statically the form works properly. Error:System.Data.SqlClient.SqlException: The column prefix 'System.Security.Principal' does not match with a table name or alias name used in the query. Here's a piece of the code that is supposed to detect the current logged in user. However, it gives the error. (some of the code may be redundant but its not causing issues that I can tell) public void InitPage() { IPrincipal p = HttpContext.Current.User; String myid = HttpContext.Current.User.ToString(); SqlServer sqlServer = new SqlServer(Util.SqlConnectionString()); DataTable dt; SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["myconnection"].ConnectionString); SqlDataAdapter cmd1 = new SqlDataAdapter("select * from USER WHERE USER_NAME = "+ myid, cnn); DataTable UIDtable = new DataTable(); cmd1.Fill(UIDtable); User_Id.Value = UIDtable.Rows[0]["ID"].ToString(); dt = sqlServer.USER_SELECT(Util.SiteURL(Request.QueryString["Pg"].ToString()), User_Id.Value);

Given below is my code: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE GetLastProjectNumber (@DeptCode varchar(20)) AS BEGIN TRANSACTION SET NOCOUNT ON DECLARE @ProjectNumber int SET @ProjectNumber = 'ProjectNumber' + REPLACE(CONVERT(char,@DeptCode),'.','') SELECT MAX(@ProjectNumber) FROM 'tbl_ProjectNumber' + REPLACE(CONVERT(char,@DeptCode),'.',''); END TRANSACTION Basically, I have a bunch of tables which were created dynamically using the code from this post and now I need to access the last row in a table that matches the supplied DeptCode. This is the error I get:Msg 102, Level 15, State 1, Procedure GetLastProjectNumber, Line 29Incorrect syntax near 'tbl_ProjectNumber'. Any help would be appreciated.Thanks.

Use A Variable Along With The FROM Clause In SELECT Statement
I have a table 'table_list' which contains two columns, table_name and a record_count. This table stores a list of tables and their corresponding record counts. What I am trying to do is, to be able to write a select statement, that can read each table name in the 'table_name' column, execute a select count(*) for the same, and update its record_count with the result of select count(*). This is the code in my procedure.. DECLARE @tab_list CURSOR set @tab_list = CURSOR FOR select * from table_list OPEN @tab_list DECLARE @tab_name varchar(256) DECLARE @rec_cnt int FETCH NEXT FROM @tab_list INTO @tab_name, @rec_cnt select count(*) from @tab_name This select is looping around along with FETCH till all the table names are exhausted and their counts are updated from the cursor back into the table. Problem is that, I am not able to use select count(*) from @tab_name, and its not accepting a variable there. Please help me to construct the select statement that is similiar to x=<table name> select * from x where x is a variable and the table name gets substituted. what is the syntax for it ?

Return Variable Name As Part Of Select Statement.
hey all, I have the following query: ALTER PROCEDURE [dbo].[sp_SelectMostRecentArticle] AS BEGIN DECLARE @article_id INT SELECT @article_id = ( SELECT TOP 1 article_id FROM article ORDER BY article_id DESC ) DECLARE @comment_count INT SELECT @comment_count = ( SELECT COUNT(comment_id) FROM comment JOIN article ON article_id = comment_article_id GROUP BY article_id HAVING article_id = @article_id ) SELECT TOP 1 article_id, article_author_id, article_title, article_body, article_post_date, article_edit_date, article_status, article_author_id article_author_ip, author_display_name, category_id, category_name--, comment_count AS @comment_count FROM article JOIN author ON author_id = article_author_id JOIN category ON category_id = article_category_id GROUP BY article_id, article_title, article_body, article_post_date, article_edit_date, article_status, article_author_ip,article_author_id, author_display_name, category_id, category_name HAVING article_id = @article_id END GO as you can see, im trying to return a comment_count value, but the only way I can do this is by defining the variable. I have had to do it this way, because I cannot say COUNT(comment.comment_id) AS comment_count or it returns an error that it cant reference the comment.comment_id. But when change it to FROM article, comment; I get errors about the article_author_id and article_comment_id. And i cant add a join, because it would return the amount of rows of the comment... unless someone could help with what i Just decribed (as i would prefer to do it this way), how would i return the variable value as part of the select statement? Cheers

Unable To Create Variable Select Statement In For Each Loop
What I'm trying to do is this; I have a table with Year , Account and Amount as fields. I want to SELECT Year, Account, sum(Amount) AS Amt FROM GLTable WHERE Year <= varYear varYear being a variable which is each year from a query SELECT Distinct Year FROM GLTable My thought was that I would need to pass a variable into a select statement which then would be used as the source in my Data Flow Task. What I have done is to defined two variables as follows Name: varYear (this will hold the year) Scope: Package Data type: String Name:vSQL (This will hold a SQL statement using the varYear) Scope: Package Data type: String Value: "SELECT Year, Account, sum(Amount) AS Amount FROM GLTable WHERE Year <=" + @[User::varYear] I've created a SQL Task as follows Result set: Full Result Set Connection Type: OLE DB SQL Statement: SELECT DISTINCT Year FROM GLTable Result Name: 0 Variable Name: User::varYear Next I created a For Each Loop container with the following parameters Enumerator: Foreach ADO Enumerator ADO Object source Variable: User::varYear Enumeration Mode: Rows in First Table I then created a Data Flow Task in the Foreach Loop Container and as the source used OLE DB Source as follows Data Access Mode: SQL Command from Variable Variable Name: User::varYear However this returns a couple of errors "Statement(s) could not be prepared." and "Incorrect syntax near '='.". I'm not sure what is wrong or if this is the right way to accomplish what I am trying to do. I got this from another thread "Passing Variables" started 15 Nov 2005. Any help would be most appreciated. Regards, Bill

Combing In A Cursor, A Select Statement With The WHERE Clause Stored In A Variable
Hi I am ramesh here from go-events.com I am using sql mail to send out emails to my mailing list I have difficulty combining a select statement with a where clause stored in a variable inside a cursor The users select the mail content and frequency of delivery and i deliver the mail I use lots of queries and a stored procedure to retrieve thier preferences. In the end i use a cursor to send out mails to each of them. Because my query is dynamic, the where clause of my select statement is stored in a variable. I have the following code that does not work For example DECLARE overdue3 CURSOR LOCAL FORWARD_ONLY FOR SELECT DISTINCT Events.E_Name, Events.E_SDate, Events.E_City, Events.E_ID FROM Events, IndustryEvents + @sqlquery2 OPEN overdue3 I get an error message at the '+' sign which says, cannot use empty object or column names, use a single space if necessary How do I combine the select statement with the where clause? Help me...I need help urgently

Random Selection From Table Variable In Subquery As A Column In Select Statement
Consider the below code: I am trying to find a way so that my select statement (which will actually be used to insert records) can randomly place values in the Source and Type columns that it selects from a list which in this case is records in a table variable. I dont really want to perform the insert inside a loop since the production version will work with millions of records. Anyone have any suggestions of how to change the subqueries that constitute these columns so that they are randomized? SET NOCOUNT ON Declare @RandomRecordCount as int, @Counter as int Select @RandomRecordCount = 1000 Declare @Type table (Name nvarchar(200) NOT NULL) Declare @Source table (Name nvarchar(200) NOT NULL) Declare @Users table (Name nvarchar(200) NOT NULL) Declare @NumericBase table (Number int not null) Set @Counter = 0 while @Counter < @RandomRecordCount begin Insert into @NumericBase(Number)Values(@Counter) set @Counter = @Counter + 1 end Insert into @Type(Name) Select 'Type: Buick' UNION ALL Select 'Type: Cadillac' UNION ALL Select 'Type: Chevrolet' UNION ALL Select 'Type: GMC' Insert into @Source(Name) Select 'Source: Japan' UNION ALL Select 'Source: China' UNION ALL Select 'Source: Spain' UNION ALL Select 'Source: India' UNION ALL Select 'Source: USA' Insert into @Users(Name) Select 'keith' UNION ALL Select 'kevin' UNION ALL Select 'chris' UNION ALL Select 'chad' UNION ALL Select 'brian' select 1 ProviderId, -- static value '' Identifier, '' ClassificationCode, (select TOP 1 Name from @Source order by newid()) Source, (select TOP 1 Name from @Type order by newid()) Type from @NumericBase SET NOCOUNT OFF

Storing Results Into Variables
I need to manage the number of rows affected by a query. If I run this script on my database: SELECT COUNT(*) FROM TABLE_NAME WHERE TABLE_NAME.FLAG = 'I' AND NOT EXISTS (SELECT* FROMERR_TABLE_NAME WHERE ERR_TABLE_NAME.FIELD_1 = TABLE_NAME.FIELD_1 AND ERR_TABLE_NAME.FIELD_2 = TABLE_NAME.FIELD_2) the query analyzer gives me back the number of lines affected: ----------- 4,00 (1 row(s) affected) I need to manage this amount (4,00), so I applied this modification: DECLARE @NUM_ROWS INT SET @NUM_ROWS = (SELECT COUNT(*) FROM TABLE_NAME WHERE TABLE_NAME.FLAG = 'I' AND NOT EXISTS (SELECT* FROMERR_TABLE_NAME WHERE ERR_TABLE_NAME.FIELD_1 = TABLE_NAME.FIELD_1 AND ERR_TABLE_NAME.FIELD_2 = TABLE_NAME.FIELD_2) ) but it doesn't work!! the SRV returns me this: Server: Msg 107, Level 16, State 3, Line 3 The column prefix 'TABLE_NAME' does not match with a table name or alias name used in the query. Do you know another way to store the number of rows affected?

Storing Daily Cached Query Results In SQL Server
I'm working on a reporting tool that could bring back hundreds of thousands of results back at once. I need some way to run the actual query only once a day, and then the reporting tool would just pull back this cached results. To be short, I need to figure out how to do this using a minimum amount of resources. Would a DataView work with something like this? How would I have it update only once a day? I appreciate any advice!

Speeding Up Site By Storing Query Results In File
Hello, We have some queries that are long and intensive. We have thought about running the queries and storing the data in a text file for lookup from our website. Example: Our online store only displays items that are in stock so when a user selects a category a query runs and grabs only items that are in stock and then displays them. There could be thousands of items the query needs to sort through before displaying the items that are in stock. What if we ran this query once every hours an stored the results in a txt file? The asp page would then go to the text file to grab the results instead of having to run the query every time a user selects a category. Will this speed up the site by not having to query every time? Would this be a correct way to eliminate queries that run thousands of times a day? thanks Andy

Storing Part Of An Express To A Variable
I know this can be done, because I saw it and tried it once. But did not use it at the time and consequently forgot how. I am storing an expression to a variable @Var Varchar(50) @Var = ('aa','bb','cc') I want to: Select * from Table WHERE Field IN @Var Substituting my variable for the " ('aa',bb','cc') which I can build dynamically...thus the use. Purpose: I have an aggregate query that currently has a CASE statement based on the contents of ('aa',bb','cc'). However, those contents can change. The aggregate will not allow the subquery (SELECT Field FROM Table). What I remember looked something like: SELECT * FROM Table WHERE field in ' & @Var &'.
