Looping Thru Records To Find Related Records
Oct 31, 2007
Hi, I have had this problem for a while and have not been able solve it.
What im looking at doing is looping thru my patient table and trying to organise the patients in to there admission sequence, so when patient "A" comes in and is treated at my hospital and is discharged and admitted to another Hospital within one day then patient "A" will get a code of 1 being there first admission.
then if patient "A" is admitted again but there admission date is greater than one day they get a code of 2 being for there second admission but will need to loop thru table looking for other admissions and discharges.
The table name is Adm_disc_Match_tbl
Basically what i have 4 fields.
Index_key = which is the patient common link (text)
ur_episode = this wil change for each Hospital (text)
Admission_datetime = patient admission date and time (datetime)
Discharge_datetime = patient discharge date and time (datetime)
example of data
Code: ( text )
Index_key,ur_episode,Admission_datetime,discharge_ datetime

Hello,
I have following VB code, in which I open a table and check whether there are records:
Dim SQL_CONNECTION_NTFNS As New SqlConnection
Dim SQL_COMMAND_NTFNS As New SqlCommand
Dim SQL_DATASET_NTFNS As New DataSet
Dim SQL_ADAPTER_NTFNS As New SqlDataAdapter(SQL_COMMAND_NTFNS)
SQL_CONNECTION_NTFNS.ConnectionString = str_DBSE_Connect
SQL_COMMAND_NTFNS.Connection = SQL_CONNECTION_NTFNS
SQL_COMMAND_NTFNS.CommandText = "SELECT * FROM Table"
Try
SQL_COMMAND_NTFNS.Connection.Open()
SQL_ADAPTER_NTFNS.Fill(SQL_DATASET_NTFNS)
Dim SQL_READER_NTFNS As SqlClient.SqlDataReader = SQL_COMMAND_NTFNS.ExecuteReader
With SQL_READER_NTFNS.Read
If SQL_READER_NTFNS.HasRows Then
???????
SQL_READER_NTFNS.NextResult()
End If
End With
Catch
' Catch Something
Finally
' Dispose everything
End Try
At the ??????? I want to loop through the records and perform some actions, until it reaches the end (EOF?), thus a 'do while until loop'.
How can I do this?

I can't get my head around this:I want to select all IDs from table A that do not have a related record intable B according to some condition:Table A contains, say, Parents and table B contains Children. I want toselect all Parents that have no children called "Sally" (this is a noddyexample, reminds me of being at Uni again :) ).Any ideas?Thanks

Hi
I wanted to do a delete rows from a group of table. These tables have a common column UserID. I heard that there is something called ondelete cascade. But I don't know how to set it up and utilise it. Could someone tell me how to do it. Or point me to a tutorial which shows how to do it.
Thanks

Hi,I was wondering if it was possible to build a query that will include acolumn that will provide a count related records from another table.Although there is a way to achieve this through programming in thefront end, I would like to know if it possible to achieve the samething through a SQL statement alone.For example, say you have two related tables, Invoices andInvoiceItems. InvoiceID is the primary key of Invoices.Invoices tableInvoiceID PO_Num CompanyID-------------------------------1 37989 32 87302 43 78942 3InvoiceItems tableItemID InvoiceID PartNo Qty---------------------------------------1 1 ABA 32 1 ASLKDJ 23 1 9LF 84 2 IEPOW 185 2 EIWPD 36 2 DSSIO 17 2 EIWP 58 2 DC93 49 3 85LS0 8Then a query that has the Invoices table plus a count of InvoiceItemsfor each InvoiceID would generate this:InvoiceID PO_Num CompanyID ItemCount-------------------------------------------------1 37989 3 32 87302 4 53 78942 3 1Does anyone have any ideas how this would be done?Thank you.

Query should only return less than 3000 records but its returning over 4M. It needs to show all duplicates records.... All the info are on the same table VENDFIl, so I used a self join but it seems to be looping..
SELECT A.FEDTID, B.VENDOR, C.NPI_NUMBER
FROM VENDFIL A, VENDFIL B, VENDFIL C
GROUP BY A.FEDTID, B.VENDOR

writing the query for the following, I need to collapse the continuity. If the termdate for an ID is one day less than the effdate of the next id (for the same ID) i need to collapse the records. See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.

I am trying to delete the records in 2 related tables. The 'child' table has a field called [SETA],
I want to delete all the records in this table that contain the same info, as well all the fields in the parent table that is related to this table. They share the [ID] field as key. This is my code:
Code:
DELETE FROM Student a full outer JOIN Qualification b on a.[ID] =b.[ID] WHERE b.[SETA] = @SETA

Oh hai
This is closely related to this problem where Ryan & Peter helped me out loads (thanks again guys):
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=101989
I now have a slightly different problem. Instead of returning the cumulative counts of people related to a business unit in the hierarchy I now need to return the actual people records. I had some code, derived from the above, that worked fine until I loaded some new data. It took a while but eventually I figured out the (now obvious) reason for the error. I have tried several changes to the query and not got anywhere. Please could someone have a look and see if you can suggest the required alteration(s)?

Hi,
I have 3 tables:
Employees with the fields:idEmployee and employeeName
Roles with the fields:idRole and roleName.
An employee can have one or many roles.
I created the table EmployeeRoles with the fields: id,idEmployee,idRole.
idEmployee and idRole are foreign keys.
I want to insert a new employee into Employees table, but I have to insert idEmployee field into EmployeeRoles table.
How can I do this?
Thanks

Hi guysI'm mulling over the best way to do something and would like your input. Forgive me if this is a bit 101 - I haven't ever had to do this in SQL before!Fairly standard set up - Hierarchy table modelling the structure of an organisation.Related table associating members of staff to the hierarchy.I want to return all levels of the hierarchy and for each level I would like to know the total number of people in the level (so for a division it would be the sum of all people in the child teams).Parameters - This table will be modelling many organisations' structures - I cannot guarentee anything like "there will never be more than n levels". As such - I would strongly prefer to have something that is iterative recursive. I can change the schema to suit the method I use if necessary. Database is not transactional - I am not concerned about updating speed. SQL Server 2K5.I've tried CTE but it turns out you cannot use group by in CTEs (even in derived tables). I have not yet tried feeding it a view or similar.I have not tried nested sets, materialised paths, accumulator table - I thought I would see if there is something obvious before I start piddling around with those.Ta!

SQL Server 2005.
Schema is not fixed at this stage - small project, schema can be adapted if neccessary.
This needs to be produced in SQL Server - there is no client application.
Hi
I am really struggling to write the SQL for the following requirement and have got to the stage where I think I need someone to give me some pointers. I can't believe this is a novel requirement but I haven't had to do this before nor can find anything similar when googling.
I have a hierarchy detailing an organisation structure. Eventually the table will store many structures and these may one day be "pseudo structures" to enable really granular reporting. As such I cannot really say "there will never be more than N levels to this hierarchy". Currently I'm using a standard adjacency design. From now on I'll call the items in the table "business units".
There is a further table with a related FK declared which associates people with business units.
Requirement: Return all business units and cumulative total total of employees for each of these units (i.e. the total for each business unit will be the number of people in that unit plus the sum of the people in all the child units).
I've asked this question on dbforums but ended up a blind alley despite Peter's attempt to help. I'm starting again from scratch but feel free to review the (now dead) thread here:
http://www.dbforums.com/showthread.php?t=1629366
To summarise - I tried the CTE route but of course this evaluates the hierarchy from the top down. To fulfill the requirement, the bottom of the structure needs to be the starting point. I also tried reversing the hierarchy so that children, rather than the parent, are stored but my query fails if there are 3+ levels.
Code to reproduce problem (note - I expect that I will need to get the employee count per business unit prior to working with the hierarchy so I have flattened the schema to reflect this - I think I can handle the SQL to get the non-cumulative count per business unit ):
DECLARE @table TABLE
(
unit_codeTINYINT
, parent_codeTINYINT
, headcountINT
, PRIMARY KEY CLUSTERED (unit_code)
)
INSERT INTO @table (unit_code, parent_code, headcount)
SELECT 1, 4, 10 UNION ALL
SELECT 2, 4, 130 UNION ALL
SELECT 3, 10, 93 UNION ALL
SELECT 4, 10, 7 UNION ALL
SELECT 10, NULL, 1
Required output:
unit_codecumulative_headcount

I need a boost to understand how to get started on solving this SQL Query.
TicketId Seq StatusDateTime
T10001 1 2015-05-04 15:54:00.000
T10001 2 2015-05-04 16:35:00.000
T10001 3 2015-05-04 16:42:00.000
T10001 4 2015-05-05 08:19:00.000
T10002 1 2015-05-04 15:56:00.000
T10002 2 2015-05-04 15:57:00.000
I need to find the total StatusDateTime for each TicketId
I need to find the average StatusDateTime for all TicketIDs
Ex. TicketId, "T10001", has 4 records based on the Seq column.
By using this, I should be able to find the amount of time between the first Seq and the last Seq to get a total time span for Ticket.
Expanding on this, I should be able to add up all of the Ticket's calculated time spans and divide by the number of tickets to get the average time span.

I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField
from MyOptions
where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField
from MyTimetable
where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.

I have a table that has multiple transactions for stock items.
This table holds all records relating to items that are inducted onto the system and there movement. For each stock item i am interested in getting the drop destination, if it has one, and only when it follows the sequential order of "Inducted>OnTransport>Dropped" (this sequence isn't always the case). Also note the CreatedDate for the Inducted and OnTransport records for the valid sequences are always the same. Below is a valid sequence for a stock item so i would want to return 'Lane01' for the Destination of this occurrence of the stock item, if this item didn't have a valid drop location then destination would be blank. Also note each stock item can be inducted more than one time per-day.
I think i have managed to build the below sql but it will only do one item at a time, so would have to wrap it in a function. Is there a way of writing a set based select statement that gets all the inducted items and for the ones that do follow the "Inducted>OnTransport>Dropped" return the destination it was dropped at? I've attached scrips below:
DECLARE @StockItemID nVarchar(128)
DECLARE @CreateDate DATETIME
Set @StockItemID='8cbe17da-6079-4170-b27a-41c0d38830f6'
Set @CreateDate = CAST('2015-08-31 13:52:39.890' AS datetime)
[Code] ....

Terminology question:Is there a term for a set of records related directly or indirectly by keyvalue in several tables? For example, a single invoice record and its lineitem records -or- a single customer, the customer's orders, the order linesfor those orders, the customer's invoices, and the invoice lines for thoseinvoices.I'm thinking the term might be graph, but I'm not at all certain of this.Thanks,Steve J

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.

Hello,
Having trouble describing my problem……
I have the table below, and I am trying to retrieve TileIDs that have the same ModelIDs.
ModelID TileID
HP DL380 G3 120v Dual15400
HP DL380 G3 120v Dual15400
HP DL380 G3 120v Dual15400
HP DL380 G3 120v Dual15400
HP DL380 G3 120v Dual15400
HP DL380 G3 120v Dual15400
Sun SF 280R 120v 15401
Sun SF 280R 120v 15401
Sun SF 280R 120v 15401
Sun SF 280R 120v 15401
Lantronix MSS4 15401
So TileID ‘15400’ would be a keeper, since all ModelIDs are the same.
Any help would be appreciated.
Thanks

Hi All, I am trying to find records when searchProductCount = 2 AND when searchProductCount < 2 BUT productID not in (select pid from TableB) ... I have the query below ... but is there any other better way to do this?
TableB has IDs: 100, 700 ...etc
eg: searchProduct ID is 50,100
-- means returns everything when we found ALL productID (50,100) from TableA, count =2
Select productName, productID from TableA where searchProductCount = 2 AND productID IN (50,100)
union all
-- when not all productID found in TableA, we only return productsID from TableA which ID found in TableB, count < 2
Select productName, productID from TableA where searchProductCount < 2 and productID IN (select pid from TableB) -- in this case, pid found in TableB from searchProductID will be 100
------------------------------------------------------------------
it comes out there are duplicates results (when first query is valid, we union all second query, so we have duplicates records). How can we eliminate the duplicates? Or is there better way to acheive this without using union all?

Hello board,
I was wondering if anyone can tell me an easy way to find duplicate records on sql. The thing is this, at work we have a database (table) which includes tracking numbers, I need a easy way to be able to search this table for duplicate tracking numbers and print them out. I currently access this table to edit some data by using the following path “Start > Programs > Microsoft SQL Server > Enterprise Manager” then work my down the tree to “Databases > Master > Tables” on tables I do a right click and “open table/query”. Any help would be most appreciated. Believe me I’m very “SQL illiterate”
Bill

Hi,
As far as I know in SQL Server 6.5 there is no concept called rowid. How can I find duplicate records in a table and delete them.
Thanks,

I have this query that I have been using to find duplicate records works great except for now. The logic I am adding is pcs_rreas <> 'NG'. When I add this it does take out the NG, but it also excludes the reocords that have NULL data in this field. I don't want that to happen. How can I fix this? I tried adding (pcs_rreas <> 'NG' or pcs_rreas is null) but nothing is pulling now.
SELECT pcs_id1, pcs_rreas, pcs_lname, pcs_fname, pcs_minit, pcs_degree, pcs_xtyp, pcs_office, pcs_dba, pcs_dob, pcs_sex, pcs_eff, pcs_trm, pcs_spec1, pcs_spec2, pcs_spec3,
pcs_spec4, pcs_tax1, pcs_ssn, pcs_altid, pcs_upin, pcs_medic, pcs_mcaid, pcs_ecs, pcs_npi, pcs_status, pcs_dir, pcs_den, pcs_www, pcs_hold, pcs_email,
pcs_misc1, pcs_misc2, pcs_newdt, pcs_newby, pcs_chgdt, pcs_chgby, pcs_malp, pcs_pf, pcs_ctl, pcs_sys, pcs_pay, pcs_ann, pcs_bcert, pcs_pass, pcs_w9,
pcs_taxex, pcs_tax2, pcs_type, pcs_rreas, pcs_routo, pcs_rtime, pcs_rdate, pcs_force, pcs_flag, pcs_v419, pcs_bcity, pcs_bstate,

Hi all,
I have a question regarding SQL Server Performance and would be grateful for a tip. Let's say I have a DB with 50.000 records. These records belong to 1.000 different datasets, so there is 1 actual and 49 historical data records. For example a company with 1000 employees has a database where each year a new record is created for each employee so after 50 years they have 50.000 records (50 years x 1000 employees). 1 record is actual, and 49 are historical. What is the best way to store this? Main target is performance for the enduser, so when an employee clicks "See all my records" it should be fast. But on the other hand the application mainly works only with the current year. Additionally it should also be fast for the boss of business unit who wants to see the latest records of his e.g. 100 employees. I have some ideas and would like to get your opinion:
1. Retrieve by latest date
Just store the records. To get the current year just select the record with the latest year. Disadvantage might be with larger databases: If the company switches to store the requests per month, each user would have 600 records (12 months x 50 years). Each time the latest record should be retrieved, 600 recards have to be compared regarding the latest date (or sorted by date descending using Top1, but this might be a problem for the boss then? Or could this be combined for a group if the boss wants to see all the latest records of his employees?).
2. Add a 'IsCurrent'-Flag
Each time a new record is stored it should be compared to the latest record. If it is newer, the 'IsCurrent'-Flag should be removed and then checked on the new record. This should be fast processed (because on saving a new record it only needs to be checked against the currently 'IsCurrent'-flagged record), and for retrieving the current record no further comparison is necessary. But how could I do this? I need to update the "AddRecord"-SP with this comparison, but I don't know how to do this.
Currently number 2 is my favorite, I just don't know how to do it ;-) What is your opinion about it, and could you include an example?
Thanks

Hello,
I would like to find all the records that contain only digits. So far, I have this:
SELECT *
FROM tmp1
WHERE (word LIKE N'[0-9]')
It returns only ten results, each containing a single digit. What I need is to find all the records of any length containing only digits, like '378', '2005', etc. but not records containing both digits and other stuff (e.g. letters) like 'I95' or 'P2P'.
Any idea?

There are 5 links at Slot 1 , that's generate error. But why? What does it mean - "The text, ntext, or image node at page (1:377289), slot 1, text ID 897099563008 is not referenced" ???
I saw other pages (not 'broken') - there is: Blob Fragment don't contains links - links are in other pages.
What are these 'broken' records in my example - they are chunks of lost information, that i can't recover?
Or not? May be exists a way, that i find all 'broken' records? Because, my table contains 192 records. But there is BLOB field - and i can't check consistency of every file, that uploaded in my table. In addition I will fully appreciate this problem.
At last, if i find record, i run checktable with repair_allow_data_loss, then upload file again.
p.s. These errors contained in backup too.

I need to delete records from a table (Table1) which has a foreign key column in a related table (Table2).
Table1 columns are: table1Id; Name. Table2 columns include Table2.table1Id which is the foreign key to Table1.
What is the syntax to delete records from Table1 using Table1.Name='some name' and remove any records in Table2 that have Table2.table1Id equal to Table1.table1Id?
