Hi All, Can we use the while loop inside a select statement? Meaning, something like this:
Code Block SELECT DATE, WHILE (SELECT TOP 1 DATEPART(HH,DATE) FROM SC_DATEDIMENSION_TABLE) <= 23 (SELECT DATEADD(HH,6,SC_DATEDIMENSION_TABLE.DATE) ) FROM SC_DATEDIMENSION_TABLE
What I want to do here is I have a table which has all the dates but with time only representing 00 hrs. I want to display this column and along side, I want to have another column, which displays the date split at 6 hours. So, one left column, there will 4 columns on the right.
Hi, can you add a counter inside a select statement to get a unique id line of the rows? In my forum i have a page that displays a users past posts in the forum, these are first sorted according to their topicID and then they are sorted after creation date. What i want is in the select statement is to create a counter to get a new numeric order. This is the normal way: SELECT id, post, comment, created FROM forum_posts WHERE (topicID = @topicID) ... some more where/order by statements This is what i want: DECLARE @tempCounter bigintSET @tempCounter = 0SELECT @tempCounter, id, post, comment, created FROM forum_posts WHERE (topicID = @topicID)... some more where/order by statements and at the end.. (SELECT @tempCounter = @tempCounter + 1) Anyone know if this can be done?
I have a need to execute a cursor inside a select statment, but I'm having problems figuring this out. The reason this need to be inside a select statement is that I am inserting the cursor logic into a query expression in PeopleSoft Query.
So! Here's the statement that works:
====================== DECLARE @fixeddate datetime DECLARE @CVG_ELECT char(1) DECLARE @Effdt datetime DECLARE EFFDTS CURSOR FOR SELECT Z.EFFDT, COVERAGE_ELECT FROM PS_LIFE_ADD_BEN Z WHERE Z.EMPLID = '1000' AND Z.EFFDT <= GETDATE() AND Z.PLAN_TYPE = '20' ORDER BY Z.EFFDT DESC OPEN EFFDTS FETCH NEXT FROM EFFDTS INTO @Effdt, @CVG_ELECT WHILE @@FETCH_STATUS = 0 BEGIN if @CVG_ELECT <> 'E' break ELSE SET @fixeddate = @Effdt FETCH NEXT FROM EFFDTS INTO @Effdt, @CVG_ELECT END
CLOSE EFFDTS DEALLOCATE EFFDTS PRINT @fixeddate
====================== If I execute this in SQL Query Analyzer it gives me the data I am looking for. However, if I try to paste this into a select statement, it goes boom (actually, it says "Incorrect syntax near the keyword 'DECLARE'.", but you get the idea).
Is it possible to encapsulate this inside a select statement?
I want to write a select statement that will show only distinct Student IDs where every record in the table with that student id has a grade above 80? Lets say for example the table looks like this:
Student_ID
Grade
11276
93
56879
81
11276
76
44327
92
11276
84
56879
97
56879
82 The select statement should only show students, 56879 & 44327 because student 11276 made a 76 in one class.Anyone know how to word this select statement?Thanks for any help!
I'm running a select statement from within my VB.net code. However, if the software package name that I chose from a drop down list in my form is not available in the search (in the TableColumn called Software.Package_Name), I would like to be able to write the message "Record Not Found" to the Package_Name "ListBox" column.
Here's the select statement: "SELECT n.Workstation_Name , s.install_status , s.install_date , s.name , s.version , s.build , s.Package_Name , n.city , n.state FROM software s , network n where ( s.mac=n.mac AND n.Workstation_Name='B001617CA709E' ) AND ( s.name='Adobe Reader' AND s.Install_status='1') ORDER BY n.Workstation_Name ASC"
My ListBox control is named lstQueryResults and uses a Structure that is one to one with each row of the lstQueryResults control. i.e.
Public Class LIST_CTRL_DATA
Public WksName As String
Public InstallStatus As String
Public InstallDate As String
Public PackageName As String
Public AppName As String
Public Version As String
Public Build As String
Public City As String
Public State As String
Public Percent As UInteger
Finally, here's the While..End routine that plugs the data into the ListBox called lstQueryResults.
Any ideas on whether or not you can write an If..Then Else statement within the SQL Select Statement and if so how? I'm still somewhat new to SQL. Any assistance would be great.

Hi everyone, I have the following problem withj this query:
SELECT DocNumber, Title,FirstName,LastName,Paper, ANNO,Location,Keywords, URL= case WHEN URL IS NULL THEN '|<a href=''https://illiad.library.nova.edu/illiad/FNN/illiad.dll?ILLiadRedirect=OpenURL&genre=thesis&isbn='+CONVERT(varchar,DocNumber)+'&title='+CONVERT(varchar,Title)+'&rft.pub='+CONVERT(varchar,Program)+'&rft.edition='+ CONVERT(varchar,Paper) +'&date='+ CONVERT(varchar,ANNO)+ '&aulast=' + CONVERT(varchar,Lastname) + '&aufirst=' + CONVERT(varchar,Firstname)+ '&url_ver=Z39.88-2004&rfr_id=info:sid/MARPS:Practicum''target=''blank'')> Order through ILLiad</a>' ELSE URL END FROM DocTable1 WHERE FREETEXT....
When URL is null, I don't get the string showing. It works properly only in the query analyzer.
Hey guys, i'm trying to use a CASE within a select but i'm not sure how to get started.
Here is my select so far, i'm inserting into a temp table that is used within a loop to gather data from my trigger:
Code:
insert into @temp_par select CONVERT(varchar(20),d.PAT_ID), ep.EXT_PAT_ID, d.DRUG_DESC_ID, d.ALLERGY_CD, CONVERT(varchar(20),d.PAR_DT,120), ISNULL(d.PAR_TXT, 'NULL'), ISNULL(REPLACE(m.DRUG_NM,'"','^"'),'NULL'), ISNULL(m.DOSAGE_FORM_CD,'NULL'), ISNULL(m.STRGTH,'NULL'), ISNULL(m.STRGTH_UM,'NULL') from deleted d --PATIENT_PRIOR_ADVERSE_REACTIONS join EXTERNAL_PATIENT ep on ep.PAT_ID = d.PAT_ID join MEDNAME m on m.DRUG_DESC_ID = d.DRUG_DESC_ID
I would like to use a CASE for the d.ALLERGY_CD column. The data in this column is usually a 1,2,3,4,5 but i'd like to convert those to their real data, for example:
Limitations: Needs to be single sql statement for exec, no udf/stored proc Objective: select aggregate count from tblPerson grouped by s_fk, division,Desc, areaDesc with rollup for totals if mail_goes_to=1, get the s_fk value via tblPerson/tblAffiliation/tblOrg/tblCity/tblCounty if mail_goes_to=2, get the s_fk value via tblPerson/tblCity/tblCounty, skipping tblAffiliation/tblOrg
What's the best method? A case statement? Would a cross-join work? Thanks so much for any and all advice!

what I am doing wrong in the case statment that I am getting an error. ?????
Hi,I am wondering how do I write a query that will take case sensitive into consideration. For example, I have "ABCD", "abcD", ABcd", "AbCd" in a table. I want to retrieve "AbCd" only from the table. This is the sql statement that I have:sqlSelect = "SELECT * FROM [al_table] WHERE [alphabet]= @alpha"Dim selectCmd As New SqlCommand(sqlSelect, myConnection) selectCmd.Parameters.AddWithValue("@alpha", "AbCd") From what I have it will return all those value. But that is not what I want. Thanks

I need a hand in this script. SELECT a.id ,value = CASE when (x1-x0) = 0 then ((Y2-Y0)-(Y1-Y0))/(0.000000001*(X2-X0)) ELSE ((-111.48277-Y0)-(Y1-Y0))/((X1-X0)*(32.72383-X0)) END ,value2 = CASE when (x1-x0) = 0 then ((Y2-Y0)-(Y1-Y0))/(0.000000001*(X2-X0)) ELSE ((-111.48277-Y0)-(Y1-Y0))/((X1-X0)*(32.72383-X0)) END FROM table_name a where value > 0 ORDER BY VALUE
The problem I'm having is in the where clause. Because the value is not a column name sql server is giving me an error. I need to evaluate the value returned. How can I get around this problem? Any sort of advise will help! Thank you in advance!
I am using a CASE statement within a SELECT query to sum up values for different customers.
SELECT CR_CUST.Customer_Code, 'General_01' = CASE WHEN CR_PROD.Part_Class_Code = '01' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END, 'General_07' = CASE WHEN CR_PROD.Part_Class_Code = '07' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END, 'General_08' = CASE WHEN CR_PROD.Part_Class_Code = '08' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END FROM CR_CUST INNER JOIN CR_INVOICE ON CR_CUST.Customer_Code = CR_INVOICE.Customer_Code INNER JOIN CR_PROD ON CR_INVOICE.Product_Code = CR_PROD.Product_Code WHERE (CR_PROD.Part_Class_Code = 1 OR CR_PROD.Part_Class_Code = 7 OR CR_PROD.Part_Class_Code = 8) GROUP BY CR_CUST.Customer_Code, CR_PROD.Part_Class_Code
My question is this - is it possible to expand my SQL Query into a Sub Query so that each customers data appears on the same line of the results?, like so...
I can achieve this by writing my results into a temporary table and extracting the data with the following SQL Query, but I just thought it would be really cool if I could do it in one SQL Statement without using a temporary table.
SELECT Customer_Code, SUM(General_01), SUM(General_07), SUM(General_08) FROM #MyTempTable GROUP BY Customer_Code
Update ed_abcdeeh set category = case when name_of_school = '' then category = 'No Facility' else '' end,status = case when name_of_school = '' then status = 'Non-Compliant' else 'Compliant' end.
How to make this query right.. when name of school is blank i want to update my category to No facility, but if the name of school has data it will just make it blank. same to the status..
Hello everybody I have problem with CASE statement. Here is select it
Code Block select mev.Id ,mev.MetaElementId ,mev.ElementValue ,mev.DocumentId ,me.ElementTypeId ,castedValue = case when me.ElementTypeId =3 then cast(mev.ElementValue as integer) when me.ElementTypeId =4 then cast(mev.ElementValue as datetime) end from dbo.tbMetaElementValue mev inner join dbo.tbMetaElement me on mev.MetaElementId = me.Id where mev.MetaElementId =7
it returns
Id MetaElementId ElementValue DocumentId ElementTypeId castedValue
49 7 2006 28 3 6/30/1905 0:00
53 7 2004 30 3 6/28/1905 0:00
61 7 2006 36 3 6/30/1905 0:00
67 7 2005 38 3 6/29/1905 0:00
70 7 2004 39 3 6/28/1905 0:00
105 7 2003 63 3 6/27/1905 0:00
166 7 2006 109 3 6/30/1905 0:00
195 7 2005 129 3 6/29/1905 0:00
220 7 2005 150 3 6/29/1905 0:00
223 7 2006 151 3 6/30/1905 0:00
As you can see it should return castedValue as integer but it cast to datetime which is wrong. If I commented line
Code Block when me.ElementTypeId =4 then cast(mev.ElementValue as datetime)
it casts everything normal, but as soon as it has more than one condition in CASE it will choose anything but not right casting
Looks like I am missing something really fundamental. Any help is apreciated !
Hi, I have created a login page (webform1) that enables me to enter my user number and password and if correct it re-directs to webform 2 where all data related to the usernumber that was entered in the login page, appears. Now I want to be able to set different re-direct pages dependant upon different users as some may require more privileges then others. As for my query I have 2 types of users: staff and managers. I want to set the login page so that if staff logins in it goes webform 3 and if manager logins in it goes webform 4. My table in the Sql database is called Users & the fields are: unumber(pk), pwd, userRole, forename, surname. I have been advised to use CASE statements, yet I do not know how to use them. Below have left my code of a simple login without the userRole validation. Please help!
