Use A Variable Along With The FROM Clause In SELECT Statement
Dec 28, 2004
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.
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?
Please can someone advise how to use SQL select statement with where clasue which is based on a textBox.text value. ex. below example I set the textbox.text value to a C# variable called TextBoxValue1 but I receive error this is not a valid This is all done in Page_Load event backend code. string strCommandtext = "Select Type.TypeName, Type.TypeDesc FROM Type Where Type.TypeName = TextBoxValue1";
I have the following stored procedure, I would like to use IF statement or something of the sort in the where clause i.e. The last line in the SP is: AND (category.categoryID = @categoryID), I only want to check this, if @categoryID is not = 12. So can I do something like this:
IF @categoryID <> 12 AND (category.categoryID = @categoryID)
STORED PROCEDURE:
CREATE PROCEDURE sp_get_total_risk_patients @categoryID int AS
SELECT COUNT(DISTINCT patient.patientID) AS total_patients FROM patient INNER JOIN patient_record ON patient.patientID = patient_record.patientID INNER JOIN sub_category ON sub_category.sub_categoryID = patient.sub_categoryID INNER JOIN category ON category.categoryID = sub_category.categoryID WHERE risk = 6 AND (completed_date = '' OR completed_date IS NULL) AND (category.categoryID = @categoryID)
I am writing a stored procedure and have a query where I create a variable from other table
Declare @Sem varchar (12) Null @Decision varchar(1) Null Select emplid,name, Semester Decision1=(select * from tbldecision where reader=1) Decision2=(select * from tbldecision where reader=2) Where Semester=@Sem And Decision1=@Decision
But I am getting error for Decision1 , Decision2. How can I do that.
I have a gridview that is based on the selection(s) in a listbox. The gridview renders fine if I only select one value from the listbox. I recive this error though when I select more that one value from the listbox: Syntax error converting the nvarchar value '4,1' to a column of data type int. If, however, I hard code 4,1 in place of @ListSelection (see below selectCommand WHERE and IN Clauses) the gridview renders perfectly. <asp:SqlDataSource ID="SqlDataSourceAll" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT DISTINCT dbo.Contacts.Title, dbo.Contacts.FirstName, dbo.Contacts.MI, dbo.Contacts.LastName, dbo.Contacts.Suffix, dbo.Contacts.Dear, dbo.Contacts.Honorific, dbo.Contacts.Address, dbo.Contacts.Address2, dbo.Contacts.City, dbo.Contacts.StateOrProvince, dbo.Contacts.PostalCode FROM dbo.Contacts INNER JOIN dbo.tblListSelection ON dbo.Contacts.ContactID = dbo.tblListSelection.contactID INNER JOIN dbo.ListDescriptions ON dbo.tblListSelection.selListID = dbo.ListDescriptions.ID WHERE (dbo.tblListSelection.selListID IN (@ListSelection)) AND (dbo.Contacts.StateOrProvince LIKE '%') ORDER BY dbo.Contacts.LastName"> <SelectParameters> <asp:Parameter Name="ListSelection" DefaultValue="1"/> </SelectParameters> </asp:SqlDataSource> The selListID column is type integer in the database. I'm using the ListBox1_selectedIndexChanged in the code behind like this where I've tried using setting my selectparameter using the label1.text value and the Requst.From(ListBox1.UniqueID) value with the same result:
Protected Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged Dim Item As ListItem For Each Item In ListBox1.Items If Item.Selected Then If Label1.Text <> "" Then Label1.Text = Label1.Text + Item.Value + "," Else Label1.Text = Item.Value + "," End If End If Next Label1.Text = Label1.Text.TrimEnd(",") SqlDataSourceAll.SelectParameters("ListSelection").DefaultValue = Request.Form(ListBox1.UniqueID) End Sub What am I doing wrong here? Thanks!

I basically want to select all GRNID's from one table but they have to be between dates in another table.So I want all GRN's between two dates found in the ABSPeriodEndDate table. To find out the start date for the between clause I need to find the MAX Period then minus 1 and the max year. To find the end date of the between clause I want I need to find both the max period and year. But I want the DateStamp column to return the results for the between clause. My query is below:
SELECT tblGRNItem.GRNID FROM tblGRNItem INNER JOIN ABSPeriodEndDates ON tblGRNItem.DateCreated = ABSPeriodEndDates.DateStamp WHERE tblGRNItem.DateCreated BETWEEN (SELECT ABSPeriodEndDates.DateStamp FROM ABSPeriodEndDates WHERE ABSPeriodEndDates.DateStamp = (SELECT
I am fairly new with SQL and still learning. I have used a case statemtent for a column in my select list and want to use the results of that statement's field in my WHERE clause but it is not working for me. Here is the code I have so far:
SELECT l.loanid, p.investorid, l.duedate, case when pc.duedate >= l.duedate then pc.duedate end as RateDueDate, pc.interestrate FROM loan l inner join participation p on p.loanid = l.loanid inner join paymentchange pc on pc.loanid = l.loanid where p.investorid = '12345' and RateDueDate is not null order by l.loanid, pc.duedate
I want to put the results of this case statment in my where clause like highlighted above but it is not working because RateDueDate is not an actual column in the table. Any help would be greatly appreciated.
I have a two tables each having a uniqueidentifier column person_id
I am trying to a select statement where I want a list of the person_id's in one table that are not in another table.
-- insert into wch_needed those who need checked
insert into #wch_needed (person_id, rendered_by ) select distinct e.person_id, e.rendered_by from #wch_who o, encounter e where o.person_id not in (select distinct person_id from #wch_have ) and o.person_id = e.person_id
the where conditional
where o.person_id not in (select distinct person_id from #wch_have )
The stored procedure, below, results in this error when I try to compile...
Msg 156, Level 15, State 1, Procedure InsertImportedReportData, Line 69 Incorrect syntax near the keyword 'ORDER'.
However the select statement itself runs perfectly well as a query, no errors.
The T-SQL manual says you can't use the keywords COMPUTE, COMPUTE BY, FOR BROWSE, and INTO in a cursor select statement, but nothing about plain old ORDER BYs.
What gives with this?
Thanks in advance R.

I have a C# application that calls a stored procedure to query the database (MSSQL 2005). I only have one field/column returned from the query but I need that column ordered.
How do I use the ORDER BY clause without returning the index column which does the sorting? The first example is NOT what I want. I want something that works like the second example which only returns the 'Name' column.
ALTER PROCEDURE [dbo].[MyProcedure]
AS
BEGIN
SELECT DISTINCT A.Name, A.index
FROM ... ... ORDER BY A.[Index], A.Name ASC
END
ALTER PROCEDURE [dbo].[MyProcedure]
AS
BEGIN
SELECT DISTINCT A.Name FROM ... ... ORDER BY A.[Index]
I have scenario where i have to pick one particular value from where condition. Here is the example:A store can have different types i-e A or B , A and B or either A or B.
Store Type Sales 11 A 1000 23 A 1980 23 B 50 5 B 560
I want to filter the store in "where clause" where
1)- if the store has type A and B, then assign only A 2)- if the store has type A associated with it then assign A 3)- if the store has type B associated with it, then assign B.
Select Store, sum(sales), Type from table1 where (TYPE]= (case when [TYPE] in ('A','B') then 'A' when [TYPE]='A' then 'A' else 'B'end)) GROUP BY [store], [TYPE]
The above statement is not working for when store has only Type B associated with it.
Is there anyway to use a variable to define a column in a select statement. I can put the variable in but I'm sure it will be read as a literal instead of the column.
Hi,I'm trying to dynamically assign the table name for a SELECT statement but can't get it to work. 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.
I have a stored procedure that accepts the table name as a parameter. Is there anyway I can use this variable in my select statement after the 'from' clause. ie "select count(*) from @Table_Name"? When I try that is says "Must declare the table variable @Table_Name". Thanks!
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);
this querry below works perfect when i assign the us.UserID = 29 but i need to be able to use the @UsersMaxID variable..... when i debug all of my values are right where they need to be... even this on ((( @UsersMaxID ))) but for some reason it will not work with the next select statement...
can someone make the pain go away and help me here..??

@[User::pda] and @[User::phone] are also variables in SSIS just like the myVar I made
I know I'm doing something wrong with the data type because it's stores the whole select statement as a string

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?
I am trying to figure out a way to retrieve a field value and assign it to a local variable with out destroying the whole structure of my T-SQL statement.
Here is the code:
DECLARE @AVERAGE_WHOLESALE_PRICE VARCHAR(20) DECLARE @ORDERBY VARCHAR(20) SELECT TOP 1 @AVERAGE_WHOLESALE_PRICE = P.NPT_PRICEX, CASE NPT_TYPE WHEN '07' THEN 1 WHEN '09' THEN 2
[Code] ....
The error message is Msg 141, Level 15, State 1, Line 3 A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations.
Everything about this query works except I'm trying to capture the @companyid (which is a variable) into a column in my table via my select statement.
My error is Invalid column name 'A113', etc. However it is the A113 I'm trying to insert into the first column of the table SAP_GLsummary

In my program i have function that will get one value from Database. Here i want to assign the output of the sql query to a local variable. Its like select emp_id into Num from emp where emp_roll=222; here NUM is local variable which was declared in my program. Is it correct.? can anyone please guide me..?
Is it possible to have an entire sql select statement as the input variable to a stored procedure? I want the stored procedure to execute the select statement.
ie.
exec sp_SomeFunc 'select * from table1 where id=1'
It may sound weird, but I have my reason for wanting to do it this way. Is this possible? if so, how do I implement this inside the stored procedure?
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.
I tend to learn from example and am used to powershell. If for instance in powershell I wanted to get-something and store it in a variable I could, then use it again in the same code. In this example of a table order items where there are order_num, quantity and item_prices how could I declare ordertotal as a variable then instead of repeating it again at "having sum", instead use the variable in its place?
Any example of such a use of a variable that still lets me select the order_num, ordertotal and group them etc? I hope to simply replace in the "having section" the agg function with "ordertotal" which bombs out.
select order_num, sum(quantity*item_price) as ordertotal from orderitems group by order_num having sum(quantity*item_price) >=50 order by ordertotal;
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?
