Hello Sir
I am working on a Teacher Evaluation Project. In my database I store results from 1-5 as evaluation indicators. I apply AVG() function on the result column. The result of the query is in integer values (i.e) 4, 3 2 or 5. I want the resutl up to two decimal places. How can i write the query to get the result in decimal form?

Hi all,
I copied the following code from Microsoft SQL Server 2005 Online (September 2007):

I am trying to code a WHERE xxxx IN ('aaa','bbb','ccc') requirement but it the return values for the IN keyword changes according to another column, thus the need for a CASE function.
WHERE GROUP.GROUP_ID = 2 AND DEPT.DEPT_ID = 'D' AND WORK_TYPE_ID IN ( CASE DEPT_ID WHEN 'D' THEN 'A','B','C' <---- ERROR WHEN 'F' THEN 'C','D ELSE 'A','B','C','D' END )
I kept on getting errors, like
Msg 156, Level 15, State 1, Line 44Incorrect syntax near the keyword 'WHERE'.
which leads me to assume that the CASE ... WHEN ... THEN statement does not allow mutiple values for result expression. Is there a way to get the SQL above to work or code the same logic in a different manner in just one simple SQL, and not a procedure or T-SQL script.
Hi!
I need to perform the following division:
declare @TotalFacts as int
declare @Totalis as int
declare @result as float
set @totalfacts = 2835
set @totalis = 4203
set @result = (@totalfacts / @totalis)
print @result
despite the @result is float, the result is 0, not 0.67.....any idea why ?
(i've tried the same with real)
Which one is good method to convert a following division into 2 decimal digits.
q1)
select cast(( cast( sum(population) as decimal) * 100) / sum(totalpopulation) as decimal(7,2)
from
table1 group by state
q2)
select cast(( sum(population) * cast( 100 as decimal)) / sum(totalpopulation) as decimal(7,2)
from
table1 group by state
q3)
select cast( (sum(population) * 100) / cast( sum(totalpopulation) as decimal) as decimal(7,2)
from
table1 group by state
q4)
select cast(( cast(sum(population) as decimal) * 100) / cast( sum(totalpopulation) as decimal) as decimal(7,2)
from
table1 group by state
q5)
select cast( (cast(sum(population) as decimal) * cast(100 as decimal) ) / cast( sum(totalpopulation) as decimal) as decimal(7,2)
from
table1 group by state
q6)
select cast(( cast(sum(population) * 100 as decimal) ) / cast( sum(totalpopulation) as decimal) as decimal(7,2)
from

I am trying to have an Excecute SQL Task return a single row result set executed on SQL Server 2005.
The query in the Execute SQL Task is:
select 735.234, 2454.123
I get a conversion error when trying to assign to SSIS variables of type Double.
I have nothing configured in the "Parameter Mapping" tab.
I have the two SSIS Double variables mapped to the Tesult Name 0 and 1 in the "Result Set" tab
I don't want to use a for loop enumerator since there is a single row returned.
I simply want to assign these two values to SSIS Double variables (double is the closest match)
I can't even hack this by converting the decimals as string and then using DirectCast to convert them to Double.
Thanks for the help
Hi,
Trying to get a dataset. My select statement is "SELECT Com_year,Avg(GPA) FROM Pilot_Stats WHERE com_source = 0 GROUP BY Pilot_Stats.com_year ORDER BY Pilot_Stats.com_year"
Where Com_Year is an integer (ie 1984, 1986, etc)
Where GPA is a decimal (ie 3.4, 3.0, etc)
Where com_source is an integer
This returns this error when I try to fill the dataset:
Decimal byte array constructor requires an array of length four containing valid decimal bytes.
For some reason it's hanging up on Averaging this Decimal column for some reason...
Anyone have an idea why? Thanks for any help!
I am having values as below:
99.87
99.96
8.67
And my output should be as:
99.8
99.9
8.6
How can I do this
Recently I have come across a requirement where i need to design a table.
There are some columns in table like below with DECIMAL Datatype:
BldgLength
BldgHeight
BldgWeight
Based on my knowledge, i know that values before Floating-Point will not be more than 4 digits.
Now as per MSDN,
Precision => 1 - 9
Storage bytes => 5
so i can create column as:
BldgLengthDECIMAL(6,2) DEFAULT 0
OR
BldgLengthDECIMAL(9,2) DEFAULT 0
Now while reading some articles, i came to know that when we do some kind of operation like SUM Or Avg, on above column then result might be larger than current data type.
So some folks suggested me that i should keep some extra space/digits considering above MATH functions, to avoid an Arithmetic Over Flow error.
So my question is what should be value of DataType for above column ?
I have been given some data from a Mainframe (AS400?) which has some fields coded in Packed Decimal. I have been able to load the data into a SQL2005 database table, but I now need to convert the Packed Decimal data in the binary(6) field to the appropriate integer (or float) value.
The field contains values such as the following:-
0x20202020200C
0x202020022025
0x20202020DFFA
I don't know how to interpret these. Has anyone got a function that can do this for me?
I've read several articles online that explain how packed decimal works, but none tell me how to interpret the last of my three examples. Can you help?
Thanks!

Need to INSERT into a different table the function value results in SELECT from a table for PurchorderNum and QtyOrder and not sure how
ALTER proc [dbo].[spCreateContainerFill]
(@containerID as nvarchar(64),
@lotNum as bigint,
@customerID as int = 1164,
[code]....
I have a table with about 28 million records in it. Each row has an ID (PK), logged (datetime), IP varchar(15)
The data grows at about 14 million records per year. I'm going to be running queries on the table that extract the MONTH or YEAR from the logged column. In Foxpro tables I would have created indexes on YEAR(logged) and MONTH(logged) so my queries would run faster. Is this possible/necessary in SQL Server?
I created a function that will return
from OpenDataSource('.....') tablename
where ... is fully populated.
However, I can't figure out how to use it?
For example
select functiona (parameter) as data_src
this returns the "from" statement above
I then try to run
select * data_src
So how do I reference the contents of data_src in the select?
Thanks for any help
Hi,
I am trying to find a way to return the result of an EXEC(*sqlstring*) from a function. I can return the tsql but not the result of an execute.
This is my function:
ALTER FUNCTION [dbo].[ReturnPickItemValue]
(
-- Add the parameters for the function here
@TypeID int,
@CaseID int
)
RETURNS varchar(max)
AS
BEGIN
-- Declare the return variable here
DECLARE @RTN varchar(max)
IF(SELECT IncludeDates FROM TBL_LU_PICK WHERE PickTypeID = @TypeID) = 1
BEGIN
SET @RTN = 'SELECT PickItem I +
CASE D.IsStartDateEstimated
WHEN 0 THEN CAST(StartDate as varchar)
ELSE CAST(dbo.ReturnEstimatedDate(D.IsStartDateEstimated, 0) as varchar)
END +
CASE D.IsEndDateEstimated
WHEN 0 THEN CAST(EndDate as varchar)
ELSE CAST(dbo.ReturnEstimatedDate(D.IsEndDateEstimated, 1) as varchar)
END
FROM TBL_LU_PICK L
INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID
INNER JOIN TBL_PICK P ON P.PickItemID = I.PickItemID
LEFT JOIN TBL_PickDates D ON D.PickID = P.PickID
WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + '
AND P.CaseID = ' + CAST(@CaseID as varchar)
END
ELSE
BEGIN
SET @RTN=
'SELECT I.PickItem
FROM TBL_LU_PICK L
INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID
INNER JOIN TBL_Pick P ON P.PickItemID = I.PickItemID
WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + '
AND CaseID = ' + CAST(@CaseID as varchar)
END
RETURN @RTN
END
Each time I try " RETURN EXEC(@RTN) " or something similar I get an error.
I have tried executing the tsql and assigning the result to a varchar and returning that varchar but i get an error.
Anyone with any ideas?
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.
thanks,

Hello all:
How can I return the result of a SELECT statement from a stored procedure (function)?
CREATE FUNCTION returnAllAuthors ()

BEGIN
// Is this right??
RETURN SELECT * FROM authors
END
Thanks!
Periodically throughout the day a report is manually pulled from a SQL Server database. Â Is their a way w/o me adding a field to the database to have the result set return the "new" results? Â For example, lets say this is our DDL
Create Table OneTwoThree
(
id int
,date11 datetime
,firefly varchar(10)
)
Insert Into OneTwoThree Values (1, '08/03/2015 18:43:32.012', 'Hi'), (2, '08/03/2015 18:44:11.011', 'No'),
(3, '08/03/2015 19:36:33.011', 'Second'), (4, '08/03/2015 19:37:33.011', 'Alpha')
Prior I could use this syntax, but that was only with needing to generate 1 result set. Â
Select id, convert(varchar(10), date11, 101) As [Date], firefly from onetwothree
where CONVERT(varchar(10), date11, 101) < CONVERT(varchar(10), GetDate(), 101)
Looking at my datetime values, let's say the 1st was generated at 18:45, obviously the 1st two records in the table would be returned. And let's say a 2nd time I need to generate I want to exclude the 1st two entries as they have already been verified. How can I do such w/o adding a field to the table?
I'm selecting the last latitude & longitude input from my database to put into the Google maps javascript function.
This is how I retrieve the longitude:
<asp:SqlDataSource ID="lon" runat="server" ConnectionString="<%$ ConnectionStrings:LocateThis %>"
SelectCommand= "SELECT @lon= SELECT [lon] lon FROM [location] WHERE time = (SELECT MAX(time) FROM [location] where year < 2008)">
</asp:SqlDataSource>
I wish to input the latitude & longitude into the JAVASCRIPT function (contained in the HTML head before the ASP) something like this:
var map = new GMap2(document.getElementById("map"));var lat = <%=lat%>;var lon = <%=lon%>;var center = new GLatLng(lat,lon);map.setCenter(center, 13);
However, lat & long do not contain the retrieved result but rather a useless System.something string.
How do I assign the retrieved results to these variables and port them over to Javascript as required?
Many thanks!
I've put a SelectCommand with an aggregate function calculation and AS into a SqlDataSource and was able to display the result of the calculation in an asp:BoundField in a GridView; there was an expression after the AS (not sure what to call it) and that expression apparently took the calculation to the GridView (so far so good).
If I write the same SELECT statement in a C# code behind file, is there a way to take the aggregate function calculation and put it into a double variable? Possibly, is the expression after an AS something
that I can manipulate into a double variable? My end goal is to insert the result of the calculation into a database.
What I have so far with the SelectCommand, the SqlDataSource and the GridView is shown below in case this helps:
<asp:GridView class="gridview" ID="GridView2" runat="server" AutoGenerateColumns="False" DataSourceID="lbsgalDataSource">
<Columns>
<asp:BoundField DataField="Formulation" HeaderText="Formulation" SortExpression="Formulation" />
<asp:BoundField DataField="lbs" HeaderText="lbs" SortExpression="lbs" />
<asp:BoundField DataField="gal" HeaderText="gallons" SortExpression="gal" />
<asp:BoundField DataField="density" HeaderText="density" SortExpression="density" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="lbsgalDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT

Hi guys n gals !
I am having a few problems manipulating the results of my data reader,To gather the data I need my code is:
// database connection SqlConnection dbcon = new SqlConnection(ConfigurationManager.AppSettings["dbcon"]);
// sql statement to select latest news item and get the posters name SqlCommand rs = new SqlCommand("select * from tblnews as news left join tblmembers as members ON news.news_posted_by = members.member_idno order by news.news_idno desc", dbcon); // open connection dbcon.Open();
// execute SqlDataReader dr = rs.ExecuteReader();
// send the data to the repeater repeater_LatestNews.DataSource = dr; repeater_LatestNews.DataBind();
Then I am using: <%#DataBinder.Eval(Container.DataItem, "news_comments")%> in my repeater.What I need to do is pass the "news_comments" item to a function I created which will then write the result. The code for my function is:
// prevent html public string StripHtml(string data) { // grab the data string theData = data;
// replace < with &alt; theData = Regex.Replace(theData, "<", "<"); // return result return theData; }
But I am having problms in doing this,Can anyone point me in the right direction on what I should be doing ???
I am working with a legacy SQL server database from SQL Server 2000. I noticed that in some places that they use decimal data types, that I would normally think they should be using integer data types. Why is this does anyone know?
Example: AutomobileTypeId (PK, decimal(10,0), not null)
I am creating a table on SQL Server. One of the columns in this new table contains whole integer as wells as decimal values (i.e. 4500 0.9876). I currently have this column defined as Decimal(12,4). This adds 4 digits after the decimal point to the whole integers. Is there a data type that will have the decimal point only for decimal values and no decimal point for the whole integers?

My database stores the decimals in Spanish format; "," (comma) as decimal separator.
I need to convert decimal nvarchar values (with comma as decimal separator) as a decimal or int.
Any Case using CAST or CONVERT, For Decimal or Int gives me the following error:
Error converting data type varchar to numeric
Any knows how to resolve.
Or any knows any parameter or similar, to indicate to the Cast or Convert, that the decimal separator is a comma instead a dot.
Hello!
I would like to cast (convert) data type decimal(24,4) to
decimal(21,4). I could not do this using standard casting function
CAST(@variable as decimal(21,4)) or CONVERT(decimal(21,4),@variable)
because of the following error: "Arithmetic overflow error converting
numeric to data type numeric." Is that because of possible loss of the
value?
Thanks for giving me any advice,

I wanted to convert a dataset from vb.net (2.0) to an .XLS file, by MS Jet. My national standard is using decimal commas, not decimal points for numbers signing the beginning of decimal places.
But the MS Jet Engine uses decimal point,in default. Therefore, in the Excel file only string formatted cells can welcome this data, not number formatted.
How can I solve or get around this problem? (with jet if it possible)

I am designing some reports for a German branch of my company and need to replace decimal point with a comma and the thousand comma seperator with a decimal point.
e.g.
‚¬1,500,123.00 to ‚¬1.500.123,00
Is there a property that I can change in the report designer to allow this to happen or is this something I need to convert in a Stored Proc.
Any help would be much appreciated

I need to return a table of values calculated from other tables. I have about 10 reports which will use approx. 6 different table structures.
Would it be better performance wise to create a physical table in the database to update while calculating using an identity field to id the stored procedure call, return the data and delete the records. For Example:
DataUserID, StrVal1,Strval2,StrVal4,IntVal1,IntVal2,FloatVal1...
Or using a table-valued function to return a temp table as the result.
I just dont know which overhead is worst, creating a table per function call, or using a defined table then deleting the result set per sp call.
