Finding Rows With Missing Related Rows
Apr 2, 2008
Hi,
I need to write a query which I have never attempted before and could do with some help....
I have a Groups table and a Users_Groups look up table. In this model, users can only be assigned to 1 group. If a group is deleted, a trigger should fire and delete any rows in User_Groups having a matching Groups.Ref. Unfortunately, the trigger hasn't been firing and I now have a load of defunct rows in Users_Groups relating users to groups which do not exist.
I now need to find all of these defunct rows in Users_Groups so that I can delete them. How can I find rows in Users_Groups where the parent rows and refs in Groups are null? I've tried searching the net for something similar but don't even know how to word the search properly to get any half relevant results.
Cheers
PS, I do realise I need to tighten the constraints on my database

Is there a way to build a select statement that will output related rows with different column data per row? I want to return something like:
rowtype| ID | value
A | 123 | alpha
B | 123 | beta
C | 123 | delta
A | 124 | some val
B | 124 | some val 2
C | 124 | some val 3
etc...
where for each ID, I have 3 rows that are associated with it and with different corresponding values.
I'm thinking that I will have to build a temp table/cursor that will get all the ID data and then loop through it to insert each rowtype data into another temp table.
i.e. each ID iteration will do something like:
insert into #someTempTable (rowtype, ID, value) values ('A', 123, 'alpha')
insert into #someTempTable (rowtype, ID, value) values ('B', 123, 'beta')
insert into #someTempTable (rowtype, ID, value) values ('C', 123, 'delta')
etc..
After my loop, I will just do a select * from #someTempTable
Is there a better, more elegant way instead of using two temp tables? I am using MSSQL 2005

When I open a table and need to make a change within a particular record...
How do I find the particular row that I am looking for? I seem to have to scroll through 600 records to find the one I need. I've found a search and replace function but it doesn't seem to work.
Thanks I appreciate any advice you can give me.

I have around 3 tables having around 20 to 30gb of data. My table A related to table B by a FK and same way table B related to table C by FK. I would like to delete all rows satisfying certain condition from table A and all corresponding related records from table B and C. I have created a query to delete the grandchild first, followed by child table and finally parent. I have used inner join in my delete query. As you all know, inner join delete operations, are going to be extremely resource Intensive especially on bigger tables.
What is the best approach to delete all these rows? There are many constraints, triggers on these tables. Also, there might be some FK relations to other tables as well.

Hi
Just thought I would ask the question on here with regards a problem we have. We have PDA based auditing tool which use SQL Compact to store information via on Compact Framework application. Now we have a user who swears blind they have carried out an audit but there is no trace of it anywhere on the database even though there are audits on there prior to the said date and after and there is no other faciity to delete data from the app other than a complete wipe of the database hence everything would of gone!
Now, the data is stored over 4 tables from which there are no traces of any unrelated data between the tables etc. so its dissappeared, anybody any experience of data simply vanishing into thin air??
Thanks in advance

I have a split string function that will take a comma delimited string and give back a table with all the values.I have a table that has a column with a comma delimited comma delimited list of states.
I can use a where clause to find one state in the table (such as all records that have CA in the states string).But need to find out how to find all the rows that have all or any of the states from a comma delimited parameter.Here is the schema
CREATE FUNCTION [dbo].[split] (@list nvarchar(MAX))
RETURNS @tbl TABLE (svar nvarchar(10) NOT NULL) AS
BEGIN
DECLARE @pos int,
@nextpos int,
@valuelen int

Hi guys,This might be simplest thing, but I am newbie to databases.I need to find out only rows modified within certain time period from adatabase. As I undertand a way out could be adding an where clause forthe time period might be an option, I might be wrong here again.But, wanted to know is there any other option. Can triggers or anyother things help me in this matter.Regards,Abhijeet

Hello,
I have a sql 2000 database in which reports are generated on a monthly basis from the data inside on of my tables. The reports have been working fine, until some of the rows seemed to have disappered!
I know the data use to be in the table, since it is showing on the old reports, however, when I try to pull that same data, it is not in the database at all.
Does anyone have any ideas on what could have caused this or how I can resolve??
Thxs!!

I have enabled drillthrough on a cube (AS 2005) and selected the columns required. This worked. When I use the drillthrough option in Excel, drillthrough queries return less rows than expected. For example, for a cells combinations (pivot table) I saw 21198 rows, but after access to detail, query return just 21106 rows. Less rows than expected.
Any ideas what causes this?
Thanks!

Hello
Iam using:
Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38
Copyright (c) 1988-2003 Microsoft Corporation
Desktop Engine on Windows NT 5.1 (Build 2600: Service Pack 2)
I am using BULK INSERT to import some pipe-delimited flat files into a database.
I am firstly converting the file using VB.NET, to ensure each line of the file has a carriage return (by using streamwriter.writeline), and I am also ensuring there is no blank line at the end of the file (by using streamwriter.write).
Once I have done this, my BULK INSERT command appears to work OK. This is how I am using the statement:
BULK INSERT
tempHISTORY
FROM 'C:TEMPHISTORY.TXT'
WITH
(
FIRSTROW = 2,
FIELDTERMINATOR = '|',
ROWTERMINATOR = '
'
)
NB: The first row in the file is a header row.
This appears to work OK, however, I have found that certain files seem to miss the final line of the file! I have analysed these files incase they have an inconsistant number of columns but they don't.
I have also found that if I knock off the last column of the tempHISTORY table, the correct number of rows are imported. However, of course, I can't just discard one of the columns from the file, I need to import the entire file.
I cannot understand why BULK INSERT is choosing to miss the final line in the file, when the schema of the destination table matches the structure of the file.

Hello everyone,
I'm trying to create a performant script to copy records from a table in a source database, to an identical table in a destination database.
In SQL 2000, I used to create a little lookup which did a count using certain fields. If the record was missing, I executed an INSERT query, otherwise an UPDATE query. The result was that the table on the destination side was always up to date. Duplicate rows were out of the question.
This was, if I'm not mistaking, a Data Transformation, using a bit of custom VBA code to govern the transfer. For each source row, the custom code was executed. Depending on the result of the custom code, a different query was launched.
Now I'm trying to do the same using SSIS in SQL 2005. Is there a task which does this for me, or do I have to script again? In the latter case, which type of task would I use?
(I thought of the Script Task, but then I would need to set up quite a bit myself.)
Thank you,
Bram

I'm got a "folder" structure application which we'll be using as an in-house directory viewer. (In case you're wondering, it doesn't relate to any "real" folders, so using xp_cmdshell is out! )
Each folder and file record can have its own permissions, however these are assumed to inherit from the parent folder if no specific access rules have been set, basically in the same way file systems work. Each file record can only have one parent, and a folder can either have a parent or be at the root level.
Right now I'm having an issue with the inheritance of permissions. Say if I want to grant access to "Folder 1" to "Group A", then "Group B" shouldn't be able to see it. However, if I grant access to "File 1" in "Folder 1" to "Group B", then "Group B" should be able to see "Folder 1", but only see "File 1" and not the rest of the contents.
I thought I could do this with a CTE, but I'm having a bit of difficulty..
Here's the code:
CREATE TABLE #FileSystem (
FSIDINTEGER NOT NULL IDENTITY(1,1) PRIMARY KEY
,ParentFSIDINTEGER NULL
,NameVARCHAR(100)
,RecordTypeVARCHAR(1)-- (F)older, or Fi(L)e

Hi,
I have written a reporting application which has a SQL2005 backend. An import routine into SQL, written by a 3rd party, frequently fails. The main problems are missing rows in certain tables.
I am going to write an SP that will accepts a from and to date. I then want to search for rows of type X between those dates that do not exist so we then know between a date range, we have no data for these XYZ days.
I have this working by returning all rows between the dates into a dataset, sorted by date, and then running through the rows and testing if the next rows date is the next expected date. This works but I think is a very poor solution. This is all done on the client in C#.
I want to learn and implement the most efficent way of doing this. My only solution in a SP was to make a temporary table of all dates between the date range for row type X and then do a right outer join against the data table, returning all rows which are missing.
Something like this:
SELECT twmd.date
FROM #temp_table_with_all_dates ttwad
RIGHT OUTER JOIN table_with_missing_date twmd
ON ttwad.date = twmd.date
WHERE twmd.date IS NULL
Would this be a good, efficent solution, or should I just stick to my processing of a dataset in C#?
Many thanks in advance,
CB

I have a table of languages, identified by a lang_id column as follows:
LANG_IDLANG_NAME
deDeutsche
enEnglish
plPolski
trTurkish
czCzech
I also have a RESOURCES table of phrases (for translation purposes) similar to this:
res_id res_lang res_phrase
AccessDenied en Access Denied
For some rows in the resources table I do not have all language codes present so am missing some translations for a given res_id.My question is what query can I use to determine the RESOURCE.RES_IDs for which I do not have a translation for.
For example I might have a de, en, cz translation for a phrase but not a pl phrase and I need to identofy those rows in order that I can obtain translations for the missing RESOURCE rows.

Hi all,
We are using a mix of SQL 2005 and 2000 servers and our "main" database server is running SQL 2005 x64 (SP2 ver. 3042).
Our system has run perfectly for months, then subsequent to an SP2 update we are seeing several instances where the data record counts are different for several tables among all the servers.
We are using Merge Replication, with no filters and published every 2 minutes.
Any ideas?
TIA,
Michael

I was using the MDX Query Builder to create MDX queries for a SSRS report. I'm not sure what happened, but when I tried to create another dataset against the cube, the "Drop Column Fields Here" and "Drop Row Fields Here" areas were no longer available for me to drop attributes onto.
I have restarted VS, rebooted, you name it, I've tried it (short of re-installing). Has anyone encountered this and how did you "fix" it.
BTW: In order to continue working, I decided to use ProClarity to build the MDX for me and when I tried to paste it into the MDX editor, I get the following error: "The query cannot be prepared: The query must have at least one axis. ..". So, as I've seen from other posts, you can't use "any" MDX in the MDX Query Builder.

Hi all,
I have access to a stored procedure that was written previously for a process that uses the output from the stored procedure to provide input to a BCP operation in a bat file that builds a flat text file for use in a different system.
To continue with the set up, here is the stored procedure in question:
CREATE PROCEDURE [dbo].[HE_GetStks] AS
select top 15
Rating,
rank,
coname,
PriceClose,
pricechg,
DailyVol,
symbol
from
(selectf.rating,
f.rank,
s.coname,
cast ( f.priceclose as decimal(10,2)) as PriceClose,
cast ( f.pricechg as decimal(10,2)) as pricechg,
f.DailyVol,
f.symbol
from dailydata f, snames s
where f.tendcash = 0
and f.status = 1
and f.typ = 1
and f.osid = s.osid) tt
order by rating desc, rank desc
GO
The code in the calling bat file is:
REM *************************
REM BCP .WRK FILE
REM *************************
bcp "exec dailydb.[dbo].[HE_GetStks]" queryout "d:TABLESINPUTHE_GetStks.WRK" -S(local) -c -U<uname> -P<upass>
This works just peachy in the process for which it was designed, but I need to use the same stored procedure to grab the same data in order to store it in a historical table in the database. I know I could duplicate the code in a separate stored procedure that does the inserting into my database table, but I would like to avoid that and use this stored procedure in case the select statement is changed at some point in the future.
Am I missing something obvious in how to utilize this stored procedure from inside an insert statement in order to use the data it outputs? I know I cannot use an EXECUTE HE_GetStks as a subquery in my insert statement, but that is, in essence, what I am trying to accomplish.
I just wanted to bounce the issue of y'all before I go to The Boss and ask him to change the procedure to SET the data into a database table directly (change the select in the proc to an INSERT to a local table) then have the external BAT file use a GET procedure that just does the select from the local table. This is the method most of our similar jobs use when faced with this type of "intercept" task.
Any thoughts?

In a t-sql 2012 sql update script listed below, it only works for a few records since the value of TST.dbo.LockCombination.seq only contains the value of 1 in most cases. Basically for every join listed below, there should be 5 records where each record has a distinct seq value of 1, 2, 3, 4, and 5. Thus my goal is to determine how to add the missing rows to the TST.dbo.LockCombination where there are no rows for seq values of between 2 to 5. I would like to know how to insert the missing rows and then do the following update statement. Thus can you show me the sql on how to add the rows for at least one of the missing sequence numbers?
UPDATE LKC
SET LKC.combo = lockCombo2
FROM [LockerPopulation] A
JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
JOIN TST.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID AND A.lockerNumber = LKR.number

I have 3 tables...
JobRequirements (A)
JobID int
QualificationTypeID int
EmployeeQualifications (B)
EmployeeID int
QualificationTypeID int
Employee (C)
EmployeeID int
EmployeeName int
I need to return a list of all employees fit for a specific job ... The criteria is that only employees who have all the JobRequirements are returned. So if a job had 3 requirements and the employee had just 2 of those qualifications, they would not be returned. Likewise, the employee might have more qualifications than the job requires, but unless the employee has all the specific qualifications the job requires they are not included. If an employee has all the job qualifications plus they have extra qualifications then they should be returned...
How to only return those records where all the child records are present in the other table..

I was thinking last night of restructuring the way "Related Items" are pulled from the database for one of our sites. Basically at the moment it is upto the client to flag two products as related. I'm thinking of using a new method of tagging the products and then finding related products based on the tags assigned -the general code for this is below but what I want to know is, is using "IN" the most efficient way of doing this?
TIA

ON t.TagId = x.TagId
WHERE
x.ItemId = @ItemId
)
GROUP BY
i.ItemId,
i.ItemName
HAVING

Hi All,
I am using sql server 2005. I stuck out in a strange problem.
I am using view in my stored procedure, when I run the stored procedure some of the rows get skipped out means if select query have to return 10 rows then it is returning 5 rows or any other but not all, also the records displyaing is randomly coming, some time it is displaying reords 12345 next time 5678, other time 2468.
But if I run seperately the querys written in SP then it returns all the rows. Please give me solution why it is happening like this.
There are indexes in the tables.
Once I shrink the database and rebuild the indexes, from then this problem is happening. I have rebuild the indexes several time, also updated the statistics but nothing improving.
But nothing is improving

I have a conditional split in an SSIS package - one split is where if rows are returned according to a specific rule, then insert those rows into to a Recordset Destinationm which points to a variable of Object type.
How I can use this variable to email fellow users. For example, what I would like is if ANY rows are returned to the Object variable (1 or more), then I would like to execute an email SP that we have on our server.

Hello,
I have a survey (30 questions) application in a SQL server db. The application uses several relational tables. The results are arranged so that each answer is on a seperate row:
user1 answer1user1 answer2user1 answer3user2 answer1user2 answer2user2 answer3
For statistical analysis I need to transfer the results to an Excel spreadsheet (for later use in SPSS). In the spreadsheet I need the results to appear so that each user will be on a single row with all of that user's answers on that single row (A column for each answer):
user1 answer1 answer2 answer3user2 answer1 answer2 answer3
How can this be done? How can all answers of a user appear on a single row
Thanx,Danny.

Hi i tried designing a SSIS package which loads only those rows which were different from existing rows in the table , i need to timestamp the existing row with an inactive date when a update of that row is inserted (ex: same studentID )
and the newly inserted row with a insert time stamp
so as to indicate the new row as currently active, in short i need to maintain history and current rows in same table , i tried using slowly changing dimension but could not figure out, anyone experience or knowledge regarding the Data loads please respond.
example of Data would be like
exisiting data
StudentID Name AGE Sex ADDRESS INSERTTIME UPDATETIME
12 DDS 14 M XYZ ST 2/4/06 NULL
14 hgS 17 M ABC ST 3/4/07 NULL
New row to insert would be
12 DDS 15 M DFG ST 4/5/07
the data should reflect
StudentID Name AGE Sex ADDRESS INSERTTIME UPDATETIME
12 DDS 14 M XYZ ST 2/4/06 4/5/07
12 DDS 15 M DFG ST 4/5/07 NULL
14 hgS 17 M ABC ST 3/4/07 NULL
Please provide your input as much as you can even though it might not be a 100% solution.
