Transact SQL :: How To Turn Select Aggregate Function Statement Into A Variable
May 26, 2015
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;
Ok, for a bunch of cleanup that i am doing with one of my Portal Modules, i need to do some pretty wikid conversions from multi-view/stored procedure calls and put them in less spid calls.
currently, we have a web graph that is hitting the sql server some 60+ times with data queries, and lets just say, thats not good. so far i have every bit of data that i need in a pretty complex sql call, now there is only one thing left to do.
Problem: i need to call an aggregate count on the results of another aggregate function (sum) with a group by.
*ex: select count(select sum(Sales) from ActSales Group by SalesDate) from ActSales
This is seriously hurting me, because from everything i have tried, i keep getting an error at the second select in that statement. is there anotherway without using views or stored procedures to do this? i want to imbed this into my mega sql statement so i am only hitting the server up with one spid.

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
-- retrieves a list of gl balances from all companies truncate table sap_glsummary declare @companyID char(6) declare c_company cursor for select INTERID from dbo.GP_Interid open c_company fetch next from c_company into @companyID
SELECT DATEDIFF(n , LAG(CAST(Date AS DATETIME) + CAST(Time AS DATETIME), 1) OVER ( ORDER BY Date, Time ), CAST(Date AS DATETIME) + CAST(Time AS DATETIME)) FROM [DataGapTest]
Gives the right output:
NULL 1 1 3548 0
However, when I put the statement in a function, I get only zeros as the output. It's as if the lag and current value are always the same (but they are not of course).
CREATE FUNCTION dbo.GetTimeInterval(@DATE date, @TIME time) RETURNS INT AS BEGIN DECLARE @timeInterval INT SELECT @timeInterval = DATEDIFF(n , LAG(CAST(@Date AS DATETIME) + CAST(@Time AS DATETIME), 1) OVER ( ORDER BY Date, Time ), CAST(@Date AS DATETIME) + CAST(@Time AS DATETIME)) FROM dbo.[DataGapTest] RETURN @timeInterval END
I have cursor that loops through a table (the table only contains columnnames of several tables) the cursor has a variable declared @columnname. when i run the following it works fine
now i want to get the min of each column name like so
select @columnname,min(mtr_5120),0,0,0 from temp_prt ------> this works for min(mtr_5120) mtr_5120,34.5,0,0,0
now I want to generalize so I try to pass in the variable name and I do the following
select @columnname,min(@columnname),0,0,0 from temp_prt (the columname (@columnname) exists in the table temp_prt)
but now i get an error Msg 8114, Level 16, State 5, Line 29
Error converting data type varchar to decimal.how can i pass the colunmame into the min and max functions or is that at all ppossible. I also tried the following:
select @columnname,'min(' + @columnname + ')',0,0,0 from temp_prt
but i get the same error Msg 8114, Level 16, State 5, Line 29 Error converting data type varchar to decimal.
SSMS does not like mine! THis is the error that I receive:
Cannot perform an aggregate function on an expression containing an aggregate or a subquery.
And this is my syntax:
Select employeeID ,COUNT(case when rehirestatus IN (select rehirestatus from regionalemptable where rtrim(storename) = 'Location1') THEN userID ELSE 0 END) + COUNT(case when rehirestatus IN (select rehirestatus from globalemptable where rtrim(storename) = 'Location1') Then userID ELSE 0 End) FROM production GROUP BY employeeID ORDER BY employeeID
I want to count how many occurences their is of each date that is returned by my sql query. I am not sure how to add the aggregate function code to my query I know how to just tell it to count all records, but not to tell it to count for each group of dates. For example I want it to count how many times 5/6/08 shows up in the returned results and so on. Here is my query I currently have. Any help would be greatly appreciated! Thanks!
The enc_timestamp is my date field.
Select a.template_id, a.enc_timestamp, a.created_by, b.first_name, b.last_name, b.last_name +', ' + b.first_name as fullname From template_audit a Join user_mstr b on a.created_by = b.user_id GROUP BY a.template_id, a.enc_timestamp, a.created_by,b.first_name, b.last_name Having a.template_id IN (543,3172,3031,3030,3134,3135,3171,1401,1937,3985,3173,2320,57,849,1775,1400,1747,3695,3957,3750,3954,3027,3241) ORDER BY a.enc_timestamp, b.first_name, b.last_name;
Well adding it to a group by or function skews the result set. How to write this query so it displays as I need it to? This is what I have thus far, and it works as it should UNTIL I add in the line of
cast(cte.[C] As float)/cast(sum(cte.[C]) over() as float)*100 As [Rate1],
Presents the error of: Msg 8120, Level 16, State 1, Line 35 Column 'cte.[C]' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
This is my full on query -- with 3 CTE's involved to get me the actual result set I am after.
;with cte as ( select [state], case when exists (select 1 from table2 R where R.centername = d.centername) then 1 else 0 end as [L], case when exists (select 1 from table3 C where C.centername = d.centername) then 1 else 0 end as [C] FROM maintable d ),
I have a few tables I am trying to join to create a report. Everything was working fine until I tried to add an aggregate Sum function to a column (MaxCap) in table ctfBarn.
Can you provide me a way to avoid using the aggregate function Max in the following select statement?
SELECT a.clmssn,
a.cossn,
Max(b.clm_seq_num) as clm_seq_num,
Max(c.chrs_seq_num) as chrs_seq_num,
Max(b.clm_dcn_dt) as clm_dcn_dt
FROM Claim a
LEFT OUTER JOIN clmdcn b
ON a.clmssn = b.clmssn
AND a.cossn = b.cossn
AND a.clm_seq_num = b.clm_seq_num
INNER JOIN clmchrs c
ON a.clmssn = c.clmssn
AND a.cossn = c.cossn
AND a.clm_seq_num = c.clm_seq_num
Group By a.clmssn, a.cossn
Order By a.clmssn, a.cossn
I want to join another table, Juris, to get the Crnt_Office column but the aggregate function Max forces me to include Crnt_Office it in the group by clause. This results in returning all rows containing unique office codes. I only want the office code from the row with the highest Clm_Seq_Num and Juris_Seq_Num.
Juris
Clmssn = key
Cossn = key
Clm_seq_num = key
Juris_seq_num = key
Crnt_Office
The following returns incorrect results:
SELECT a.clmssn,
a.cossn,
Max(a.clm_seq_num) as clm_seq_num,
Max(c.chrs_seq_num) as chrs_seq_num,
Max(d.juris_seq_num) as juris_seq_num,
Max(b.clm_dcn_dt) as clm_dcn_dt,
d.crnt_office
FROM mt16ic_Claim a
LEFT OUTER JOIN mt16ic_clmdcn b
ON a.clmssn = b.clmssn
AND a.cossn = b.cossn
AND a.clm_seq_num = b.clm_seq_num
LEFT OUTER JOIN mt16ic_juris d
ON a.clmssn = d.clmssn
AND a.cossn = d.cossn
AND a.clm_seq_num = d.clm_seq_num
INNER JOIN mt16ic_clmchrs c
ON a.clmssn = c.clmssn
AND a.cossn = c.cossn
AND a.clm_seq_num = c.clm_seq_num
Group By a.clmssn, a.cossn, d.crnt_office
Order By a.clmssn, a.cossn
If more information is needed, I have data examples but could not include them due to character size limit. Thank you for your help.
I have a problem with an SQL-query and I don't know what the best solution would be to solve the problem.

I get the following error:
Msg 8120, Level 16, State 1, Line 25 Column 'STATI.Z4400' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
I know it has something todo with the select on the table SRTAS, but what's the best way to solve this problem without the chance of getting a wrong result.
The SELECT on SRTAS is to get the "description" of STATI.Z4414 who's stored in the table SRTAS. I only want to group on the fields that will be inserted in WERKS.Z8602, WERKS.Z8603, WERKS.Z8604, WERKS.Z8605, WERKS.Z8606. So adding STATI.Z4400 to the GROUP BY would give me wrong results?
This query is dynamicly generated from within my program from what the user selected.
Also, if there are better ways to write the query, I would be happy to get some hints and tips, but if possible without stored procedures.
I have a a Group By query which is working fine aggregating records by city. Now I have a requirement to focus on one city and then group the other cities to 'Other'. Here is the query which works:
Select [City]= CASE WHEN [City] = 'St. Louis' THEN 'St. Louis' ELSE 'Other Missouri City' END, SUM([Cars]) AS 'Total Cars' From [Output-MarketAnalysis] Where [City] IN ('St. Louis','Kansas City','Columbia', 'Jefferson City','Joplin') AND [Status] = 'Active' Group by [City]
Here is the result:
St. Louis 1000 Kansas City 800 Columbia 700 Jefferson City 650 Joplin 300
When I add this Case When statement to roll up the city information it changes the name of the city to 'Other Missouri City' however it does not aggregate all Cities with the value 'Other Missouri City':
Select [City]= CASE WHEN [City] = 'St. Louis' THEN 'St. Louis' ELSE 'Other Missouri City' END, SUM([Cars]) AS 'Total Cars' From [Output-MarketAnalysis] Where [City] IN ('St. Louis','Kansas City','Columbia', 'Jefferson City','Joplin') AND [Status] = 'Active' Group by [City]
Here is the result:
St. Louis 1000 Other Missouri City 800 Other Missouri City 700 Other Missouri City 650 Other Missouri City 300
I have a specific variation on the standard 'Column Invalid' question: I have this query that works fine:
SELECT vd.Question , csq.Q# , csq.Q_Sort , csq.Q_SubSort , AVG(CAST(vd.Response AS FLOAT)) AS AvgC , vd.RType
[Code] ....
When I add this second average column like this:
SELECT vd.Question , csq.Q# , csq.Q_Sort , csq.Q_SubSort , AVG(CAST(vd.Response AS FLOAT)) AS AvgC ,
[Code] ....
I get the error: Column 'dbo.vwData.Response' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Clearly things are in the right place before the change, so I can only assume that the OVER clause is my problem. Is this just not possible?
I have been struggling with the below transact sql user defined function. I want to use a transact sql variable in an "in" statement. I don't get any results and I am not sure if I am receiving an error or not.
Code:
DECLARE @myval varchar(50),@username varchar(50) DECLARE @rolelist varchar(2000) SET @rolelist = '' SET @myval = 'user a,user b' select @myval = ''''+ replace(@myval,',',''',''') + '''' print @myval
DECLARE User_Cursor CURSOR FOR select distinct eusername from euser where eusername in (@myval)
OPEN User_Cursor
FETCH NEXT FROM User_Cursor INTO @username
SET @myval = @username SET @rolelist = @username WHILE @@FETCH_STATUS = 0 BEGIN SET @rolelist =+ @rolelist + ',' + @username
FETCH NEXT FROM User_Cursor INTO @username END CLOSE User_Cursor DEALLOCATE User_Cursor print @myval print 'rolelist' + @rolelist GO
I am at a loss any suggestions would be greatly appreciated.
CREATE FUNCTION [dbo].[UDF_GetCode] ( @TableName NVARCHAR(50) ) RETURNS NVARCHAR(50)

This function is called in insert statement like below. exec sp_executesql N'INSERT INTO Table ([Code], [Name]) VALUES (dbo.UDF_ GetGlobal ConfigCode (''TableName''), @Name)'I am getting following error.Only functions and some extended stored procedures can be executed from within a function.
I need to create an output from a T-SQL query that picks a numeric variable and uses the print function to output with leading zeroes if it is less than three characters long when converted to string. For example if the variable is 12 the output should be 012 and if the variable is 3 the output should be 003.
Presently the syntax I am using is PRINT STR(@CLUSTER,3) . But if @CLUSTER which is numeric is less than three characters I get spaces in front.
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.

I m having problem with the "Select" function the error I m getting is Select statements included within a function cannot return data to a client (error 444)
Cann I use "select" statement in the function? If not what is the alternative?
I reduced the size of the sproc because it is a big one, I donn have any proble with syntax.
I've got a complex UDF I need to call twice in a select statement, as shown below:
SELECT
dbo.myFunction(colName), dbo.myFunction(colName) * 2 FROM
tableName
The problem is, the result of "dbo.myFunction(colName)" is not being cached, so the function is executed again for "dbo.myFunction(colName) * 2". This is having a significant impact on performance (doubling the amount of time it takes for the query to execute).
Is there any way I can write the query so that dbo.myFunction is only executed once?
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 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.
