SQL Server 2008 :: Elegant Way For Returning All Results When Subquery Returns No Results?
Mar 25, 2015
I have four tables: Customer (CustomerId INT, CountyId INT), County (CountyId INT), Search(SearchId INT), and SearchCriteria (SearchCriteriaId INT, SearchId INT, CountyId INT, [others not related to this]).
I want to search Customer based off of the Search record, which could have multiple SearchCriteria records. However, if there aren't any SearchCriteria records with CountyId populated for a given Search, I want it to assume to get all Customer records, regardless of CountyId.
Right now, I'm doing it this way.
DECLARE @SearchId INT = 100
SELECT * FROM Customer WHERE
CountyId IN
(
SELECT CASE WHEN EXISTS(SELECT CountyId FROM SearchCriteria WHERE SearchId = @SearchId)
THEN SearchCriteria.CountyId
[Code] .....
This works; it just seems cludgy. Is there a more elegant way to do this?

I have stored procedure
ALTER PROCEDURE dbo.usp_Create_Fact_Job (@startDate date, @endDate date) AS
/*--Debug--*/
--DECLARE @startDate date
--DECLARE @endDate date
--SET @startDate = '01 APR 2014'
--SET @endDate = '02 APR 2014'
;
/*-- end of Debug*/
WITH CTE_one AS ( blah blah blah)
SELECT a whole bunch of fields from the joined tables and CTEs...When I run the code inside the stored procedure by Declaring and setting the start and enddates manually the code runs in 4 minutes (missing some indexes ).When I call the stored procedure with the ExEC
DECLARE@return_value int
EXEC@return_value = [ClaimCenter].[usp_Create_Fact_Job]
@startDate = '01 apr 2014',
@endDate = '01 apr 2014'
SELECT'Return Value' = @return_value
It never returns a results set but doesn't error out either. I have left it for 40 minutes and still no joy.The sproc is reasonably complicated; 6 CTEs to find the most recent version of records and some 2 joins to parent tables (parent and grandparent), 3 joins to child tables (child, grandchild and great grandchild) and 3 joins to lookup views each of which self references a table to filter for last version of a record.

We are running SQL 2014 SP1. We are using defined Full text indexes on several tables in the database. However, on one specific set of servers, a certain search will not return any data. This exact same search works on another set of servers built identically. The first responses I'm sure will be stop list, but I have dropped and recreated the FTI multiple times with different stop lists or no stop list at all and get the same results.
The specific word being searched on is YUM. If I change the value to YUMk, it actually returns, and if I change the data to TUM it returns, but YUM does not. This exact query is working on multiple other systems, so it seems to be something environmental, but I haven't been able to pinpoint it.

I am using the following conditional select statement but it returns no results.
Declare @DepartmentName as varchar
Set @DepartmentName = null
Declare @status as bigint
Set @status = 4
IF (@DepartmentName = null) BEGIN
SELECT CallNumber AS [Call Number], Problem, Solution, Note
FROM AdminView
WHERE (Status = @status)
ORDER BY CallLoggedDT
END
ELSE IF (@DepartmentName <> null) Begin
SELECT CallNumber AS [Call Number], Problem, Solution, Note
FROM dbo.AdminView
WHERE (Status = @status) AND
(DepartmentName = @DepartmentName)
ORDER BY CallLoggedDT
end
when i run the 2nd half by itself it tells me to declare @status but not @departmentname. whats going on???

Use a subquery to narrow the results to only those customers with a yearly income that is greater than
-- or the same as the average of all customers.
-- 883 rows
SELECT C.LastName+', '+C.FirstName AS FullName, C.YearlyIncome
FROM dbo.DimCustomer AS C
JOIN (SELECT AVG(YearlyIncome) AS AVGIncome FROM dbo.DimCustomer) AS D
ON C.YearlyIncome >= D.AVGIncome
After executing this, I got a whopping 9000+ rows. How can I narrow down to 883 rows?

If I query sql server I get 10 results. But when I use if (myReader.Read()) I get only 7 results. I found that there was a Null field in the DB. I changed it and it worked.
The problem is I don't want to touch the database and set all null fields. There must be a way to get all results including the Null using sqlDataReader so that if (myReader.Read()) is used it does the right comparison.
// This code is called 10 times with a select * from where item="xxx"
P21Conn.Open();
SqlDataReader myReader = cmd.ExecuteReader();
if (myReader.Read()) {
thanks

Hello there
I have an application that allows users to book rooms in a building. I have a booking request table and a rooms booked table since there is a booking that can be made that includes multiple rooms. I have an instance where i need to select the booking requests for a particular date and need to display the rooms for each booking. Since the rooms booked table has the booking request id i'm wondering if there is a way to combine all the subquery results into one record to get around the error of having multiple records being returned in a sub query. The table structures are as follow:
bookingrequestion - bookingrequestid, startdate, enddate
roomsbooked-id, bookingrequestid, roomname
i'm basically trying to use the following query
select br.bookingrequestid, (select roomname from roomsbooked where id = br.bookingrequest) as rooms
i'd like the results of the subquery to return the room names as A,B,C. I'm trying to avoid having to obtain the recordset for the booking requests and then loop through them and for each one obtain a recordset for the rooms, seems like too many database hits to me.
thanks

Table users:
userid, name, added...
Table groups
groupid, groupname...
Table groupadmins:
userid, groupid
The users to groups relationship is many-to-many, which is why I created the intermediate table. I would like to return a recordset like:
userid, name, groupids
12344, 'Bob', '123,234,345'
If I try to just select groupid from groupadmins:
select userid, name, (select groupid from groupadmins where groupadmins.userid = users.userid) as groupids from users
then I'll get an error that a subquery is returning multiple results. Some users are not group admins and those that are may have a single or multiple groups. The only thing I can think of is to select the groupids seperately and use a cursor to loop through the results and build a string with the groupids. Then I would select the string with the rest of the fields that I want for return. Is there a better way to do this?

Say I want to search for a range of account numbers but only which are active. After I set my field for A (active) this field shows in my results, I dont want it to.
In Access you can easily just uncheck that field in design view, but how do I do it in sql?

I have a query that I created in SqlServer and then merely copied the code to a sqldatasource. They are both connected to the same db, however the sqldatasource query only returns 6 records and when run in SqlServer, it returns 52 rows which is the correct number.
Any ideas on what might be causing this? There are no filters on the sqldatasource. It only has that one query. Do they differ in the way they execute sql code?
Thanks for any help!

In sql server 2000 - our QA pointed out that his testing for empty strings returned 200 + rows but that when he clicked in the field there were obviously a space there. This issue came up because of the script I created to replace and earlier one that queried on empty strings instead of datalength and the earlier script always reported that it had updated x number of rows regardless of how many times it was run on the same database.
QA query based on the earlier script:
Select * from StringTable
WHERE (LongString = '' OR LongString IS NULL)
My script:
The fields are nvarchars in the newer database but older version of the database had varchars. I had created a script to replace empty strings as follows:
-- if LongString column is varchar - run varchar update else nvarchar update
If exists (Select * from sysobjects o
inner join syscolumns c on c.id = o.id
where c.name = 'LongString' and o.name = 'StringTable' and c.xtype = 167) begin
-- update varchar LongString
UPDATE StringTable
SET LongString = char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(LongString ) < 1) OR LongString IS NULL)
END
Else Begin
-- update nvarchar LongString
UPDATE StringTable
SET LongString = char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(LongString ) < 2) OR LongString IS NULL)
END
If exists (Select * from sysobjects o
inner join syscolumns c on c.id = o.id
where c.name = 'ShortString' and o.name = 'StringTable' and c.xtype = 167) begin
UPDATE StringTable
SET ShortString= char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(ShortString) < 1) OR ShortString IS NULL)
END
Else Begin
-- update nvarchar ShortString
UPDATE StringTable
SET ShortString= char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(ShortString) < 2) OR ShortString IS NULL)
END
My method for checking for datalength appears to work correctly why doesn't the QA script? I thought it might have to do with the nvarchar used in the table but I changed the column to a varchar and still has the same issue.
Thanks

Hi everyone, I have a stored procedure which I use to query a table.The first part of the stored procedure uses a cursor to update a temp tablewhilst the second part of the query actually retrieves information from adatabase table utilising information based on the temp table.My problem is that when I run the procedure, the cursors status is outputand therefore becomes part of the result set. I really only want theinformation returned returned by the second query as my result set.So, is it possible to hide the results of the cursor so that it does notbecome part of the result set? I have tried nocount on around the cursorroutine but this does not workThanks in advanceMark

I have the following code below where I need to have all of the query results output into a .csv file to use in a VBA macro. The issue I am running into is that the data is not deliminating correctly and my rows are being shifted incorrectly. Any better way of out putting the results into a .csv file with a common delimiter.
-- Declare the variables
DECLARE @CMD VARCHAR(4000),
@DelCMD VARCHAR(4000),
@HEADERCMD VARCHAR(4000),
@Combine VARCHAR(4000),
@Path VARCHAR(4000),
@COLUMNS VARCHAR(4000)

Output from query (please post in a text editor. The line starting with (only ) should be on line 1 after 20 pks and is shifted to a new line.):

I have a set of results based on a query that displays a learner, their workplace assessor and both their email addresses.
I want to send a standard request email (using db_mail) to each learner's email address which specifies who their individual assessor is and their current employer. One per learner.
I then want to email each assessor and in this email detail their learners (and their employer details) that I have emailed the request too.

If I use msdb..sp_send_dbmail or save query results as text (using sqlcmd) and include the column headers I get the dashed separator line.
e.g.
custID, name
------, ------
1,bob
2,jamesI would like this
custID, name
1, bob
2 ,james
I found this method [URL] ....
::
sqlcmd -E -S (local) -d myDB -W -w 1024 -s "," -i "SELECT * FROM tblCust" | findstr /V /C:- /B > C: emp.csv
Can the same result be achieved sending as attachment with dbmail?
EXEC msdb..sp_send_dbmail @attach_query_result_as_file = 1I don't want to have to add column names as part of the query
Change the query to return column headers in resultset
SELECT 'CustID' as f1, 'name' as f2
UNION ALL
SELECT CAST(CustID as Varchar(10)), name FROM tblCustand set
msdb..sp_send_dbmail @query_result_header = 0

I am/have been having an issue with Data Access from a Sql Server database. I have a class that contains a method called "GetDataReader" which takes in a string for the query. Occasionally, the DataReader returned has completely different columns thus resulting in an error when trying to read the data. Below is a small section of code that actually creates the datareader, opens the connection and executes the reader.SqlCommand cmdReader = new SqlCommand();
SqlDataReader drReturn = null;
try {
// Set the connection for the command object
cmdReader.Connection = new SqlConnection(this._csbGlobal.ConnectionString);
cmdReader.Connection.Open();
// Set the command type
cmdReader.CommandType = Type;
// Set the command text
cmdReader.CommandText = Sql;
// Set the command timeout
cmdReader.CommandTimeout = _iTimeout;
if (Parameters != null) {
// Set the parameters
for (int i = 0; i < Parameters.Count; i++) {
cmdReader.Parameters.AddWithValue("@" + Parameters.GetKey(i), Parameters[i]);
}
}
// Get the return value
drReturn = cmdReader.ExecuteReader(CommandBehavior.CloseConnection);
// Dispose of the command object
cmdReader.Dispose();
cmdReader = null;
} catch (SqlException e) {
this.HandleError(e);
} catch (Exception e) {
this.HandleError(e);
}
// Return the reader
return drReturn;The data access class is created on each page and only used for that page and any usercontrols on that page. I have checked all the datareaders and they are all being closed. I have been fighting with this issue for about a month and a half now. It only seems to happen when there are a lot of people on the site.If anyone has experienced this or konws how to fix it please let me know. Thanks-Jason

Hi all,I have a SQL job where I do the following -I check for new rows in my Table "DumpResults", every now and then and get the new rows to be inserted into table "CleanTable". I use OPENXML() to get the new data to be inserted but for some reason I don't get the right data through OPENXML() - DECLARE @intDoc INTDECLARE @xmlDoc VARCHAR(8000)IF(SELECT COUNT(*) FROM DumpResults WHERE DumpResults.C1 NOT IN (SELECT CleanTable.C1 FROM CleanTable)) > 0BEGINSET @xmlDoc = (SELECT * FROM DumpResults WHERE DumpResults.C1 NOT IN (SELECT CleanTable.C1 FROM CleanTable) FOR XML RAW) SET @xmlDoc = '<TABLE>' + @xmlDoc + '</TABLE>'
PRINT @xmlDocEXEC sp_xml_preparedocument @intDoc OUTPUT, @xmlDoc--INSERT INTO CleanTable(C1, C2, C3, C4, C5)
SELECT C1, C2, C3, C4, C5, C6 FROM OPENXML(@intDoc,'/row',1)WITH (C1 INT, C2 CHAR(3), C3 CHAR(3) , C4 FLOAT, C5 INT)EXEC sp_xml_removedocument @intDoc
END
ELSE Output that I get is - <TABLE><row C1="1" C2="AAA" C3="BBB" C4="1.000000000000000e+000" C5="2"/></TABLE>(0 row(s) affected) SO "PRINT @xmlDoc" is returning back the xml data (new results) it collected from the "DumpResults" table which isn't there in "CleanTable" but the "Select... FROM OPENXML(...)" doesn't return any result. why so? If anyone knows please reply If anyone has any better method to do it, inputs are welcome. Thanks

Hello....
I am in the process of building a search function for an application (VS2005, ASP.net, VB code, and AJAX functionality).The user's form has a textbox (for an input string) and two drop-downs. The user would then click on a "Search Now" button, and the data should populatein a Gridview to the left of the search form. I'm trying to search over an SQL database and need to know how to exactly implement what I have so far:

Here's my select statement used to initially populate the Gridview (set up using the configuration of the Gridview):SELECT [ContractID], [ContractName], [ContractType], [EffectiveDate], [TerminationDate] FROM [Contract]Here's my btnUpdateFilter codebehind (VB):
Protected Sub btnUpdateFilter_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdateFilter.Click Dim strVendorName As String Dim strContractType As String Dim strSortBy As String If txtVendorFilter IsNot "" Then strVendorName = txtVendorFilter.Text End If
''''''''''''''''''''''''''''If ddlContractTypeSearch.SelectedValue = 1 Then strContractType = "1"ElseIf ddlContractTypeSearch.SelectedValue = 2 Then strContractType = "2"ElseIf ddlContractTypeSearch.SelectedValue = 3 Then strContractType = "3"ElseIf ddlContractTypeSearch.SelectedValue = 4 Then strContractType = "4"ElseIf ddlContractTypeSearch.SelectedValue = 5 Then strContractType = "5"ElseIf ddlContractTypeSearch.SelectedValue = 6 Then strContractType = "6"ElseIf ddlContractTypeSearch.SelectedValue = 7 Then strContractType = "7"Else strContractType = "0"End If
''''''''''''''''''''''''''''''If ddlSortBy.SelectedValue = 1 Then strSortBy = "ContractName"ElseIf ddlSortBy.SelectedValue = 2 Then strSortBy = "ContractType"Else strSortBy = "ContractName"End If
End Sub
My question is, "how can I form the proper SQL statement", and then implement it so that my gridview will populate using my generated SQL Statement?
Thank you for the help!!!

I need some help. I have a function that used to use ADO.NET to return a dataview. Now I'm using linq, and I don't know how to make this work anymore.my original function looked like this: public DataView getIssue() { //do some ADO, return the dataview return ds.Tables["Articles"].DefaultView; } With this I could write Gridview1.dataSource = getIssue();I want to do the same thing with Linq, but I'm running into some trouble:Here's my function now:public DataView getIssue() { var query = from a in db.Articles join i in db.Issues on a.IssueID equals i.IssueID select a; DataView dv = new DataView(); dv = query.asdatatable(); return query; }OK, first off I can't use asdatatable since I am using a join, so I can't make the results of my query a dataview. I can't return the results of my query in this function, something that seemed simple to do in Linq now seems like something that may only be possible in ADO.Thanks for your time

You know how osql can return the results of executing a .sql script to a window? Is there any way to achieve that same behavior in .NET? I am in the process of working on an application that needs to execute a .SQL script (which is easy to do) and then return the actual SQL output from the execution to a window. How do I get that output? None of the sql data objects seem to support this.

I have this script that captures metrics and sizes using T-SQL. When running in development I have no issues. I can run under the context of any database and get results back. When deploying to production servers no results are returning. I'm trying to figure out what permissions are needed for this to return results.
No error message is being returned either. My access is limited for triage against Production? I need to be able to have Production DBA set the right permissions so this job can run correctly.

I have a query running without issue on around 100,000 results however i have a couple where my MAX aggregate is returning two results for a MAX(date time) and i cannot figure out why. I have paired down the query to try and work it out but still don't know.
My query now looks like this (i have remove most columns)
SELECT STATUS, RunOn, sort, T_ID
FROM dbo.Results
WHERE (RunOn IN
(SELECT MAX(RunOn)
FROM dbo.Results
group BY T_ID) AND T_ID = 21405)
ORDER BY sort
I added the T_ID = 21405 to restrict the results to the problematic results, if i set T_ID to any other test result i get one value based on the latest RunOn, but for some reason with this T_ID i get two values, the latest one and one slightly older... The date time looks ok, i just can't work out why the latest and one older result are returned !
The original query was grouping by more items but i removed those to try and work out what is going one, as mentioned for 99.9% of results it works perfectly, but for this one i don't know.

I have a query with a nested query that is used as an in line view. When I run the whole query I keep getting slightly different results each time (10000, 10002, 10001, 9999 etc.), nothing is being changed, no jobs are running on the DB to affect the tables etc.
When I run the inline view query with the nested query, or nested query on its own, it returns same number each time.
What could potentially be the cause of this?

Hello.
I am new at SQL and am using SQL server express edition and im a bit stuck! I am using ASP.NET and C# in my website which is using sql database back end.
String SQLroom = "SELECT DISTINCT RoomName FROM Room INNER JOIN RoomCalendar ON Room.RoomID = RoomCalendar.RoomID WHERE Capacity = '" + reqCapacity + "' " + " AND NOT ('" + newRoomEnd + "' <= roomStartDateTime OR '" + newRoomStart + "' >= roomEndDateTime) AND (OHP = '" + ohpYesNo + "' AND AV = '" + avYesNo + "') ";
This is my SQL string... what it is trying to do is:
find the room
where the capacity is the reqcapacity entered by user
and the startdatetime and enddatetime entered by the user are not present in the table for that room capacity
and then look at whether the user requires OHP or AV facilities, which are stored in the database as either yes or no values.
The problem i am having is with the condition in the sql query... because the user may require an OHP and not AV, but then the room returned "`could" have AV facilities, as it wouldnt make a difference to them if it was there or not, basically, the yes condition has to be satisfied.
Not sure whether i should be using AND, or OR? or a combination.
Any ideas gratefully appreciated....

I havea 2 part issue with a query I'm trying to run for a report.
I have an incident report that needs to show results based on dates from the week before. In addition, This report should run every Monday morning, with the exception of a Monday holiday, where in that case, the report will run the next business day. I have an idea to use a case statement, but it doesn't seem to work for me. Any suggestions?
Also,part of the query I have is pulling back the right data, as long as I don’t include parameters. When I do add values to the parameters the query includes all the dates. I need to see either/or - not both. I just want to either see dates without the param values or see only dates that I ask for in a parameter. Does that make sense?
Here’s the query (thanks!):
SELECT incident.incid_id,
incident.incid_short_desc,
incident.incid_received_date_time,
incident.incid_closed_date_time,
security_users.description,
incident.incid_assigned_to,
incident.tagged_delete_flag,
activity_result_master.result_desc,
incident_priority_master.priority_desc,
activities.result_id
FROM activities AS activities INNER JOIN
incident AS incident ON
activities.incid_id = incident.incid_id INNER JOIN
activity_result_master AS activity_result_master ON
activities.result_id =
activity_result_master.result_id
INNER JOIN security_users AS security_users ON incident.incid_assigned_to = security_users.name INNER JOIN
incident_priority_master AS incident_priority_master ON incident.priority_id = incident_priority_master.priority_id
WHERE incident.tagged_delete_flag = 'N' AND
activities.result_id = '6' AND
(incid_received_date_time >= DATEADD (d,-7,GETDATE()) AND
incid_closed_date_time <=DATEADD (d,-3,GETDATE())) OR
CONVERT(varchar,incident.incid_received_date_time,101) >= @StartDate AND CONVERT(varchar,incident.incid_closed_date_time,101) <= @EndDate
ORDER BY incident.incid_assigned_to, incident.incid_id

Hi,I wanted to know if this is possible and if so, how do Ido it. Say, I have a query "SELECT * FROM Table WHEREColumn="some_value". This executes on a very large dataset and I would like to return the results as they queryexecutes rather than wait for the whole query to execute.Basically, I want to get the results as they are preparedby the database. Any way to do this?Regards,San
