Exporting Table Structures To Another Database
Sep 26, 2006We have databases with large numbers of tables. We have a separate database for each year. For various reasons, we need to export about 100 of the tables (Structure only, not their data) from last years database into this year's database. What is the best method for doing this? The import/export wizard creates the tables but does not bring in important things like keys.

Comparing Name Fields In Same Table
Nov 29, 2014I have two name columns in my table, NAME1 & NAME2 that I want to compare to see if they match. Only problem is that the order of the first, last, middle name can be either same or different between the two fields.
For example
NAME1 = JAY JOHN SMITH
NAME2 = JOHN SMITH JAY or SMITH JOHN JAY
Is there a way to somehow reorder these fields and then compare using SQL?
Comparing List To A Table

I have a list of names, all i have to do is check to see if any of them are in a table, if they are they get deleted. The unique field of the table is title and it is what i have. I don't really know how i am meant to do this. I thought of creating a new table, placing my values into it and comparing to the already existing table, but surely their is a simple way?
Help On Comparing And Modifying A Resultset Or Table
Jun 14, 2007HI everybody need help badly on the following
have to recordsets with the following with the following SQL
SELECT place, count(minus)as countminus
order by place
group by place
THE RESULT WOULD BE
PLACE countminus
ABC 10
DEF 50
HIJ 5
KLM 2
MNO 0
MY OTHER QUERY IS
SELECT plus, count(plus) as countplus
GROUP BY plus
ORDER BY plus
THE RESULT WOULD BE:
PLUS COUNTPLUS
ABC 10
DEF 20
my problem is i need to add another column to the first resultset (if possible) or create a table with the same field and values of the first result set with the additional column OF THE second resultset COUNTPLUS...
with this condition..
I need to loop with single row from the column PLACE on the first result set and compare it with the column PLUS on the second result set. if there is a value of the PLACE=PLUS get the corresponding value of the COLUMN COUNTPLUS AND WRITE it on the COUNTPLUS ON THE NEW TABLE.. ELSE THE VALUE IS 0 this i would do it up to the END OF FILE EOF...
THE RESULT WOULD BE THIS.....
PLACE countminus COUNTPLUS
ABC 10 10
DEF 50 20
HIJ 5 0
KLM 2 0
MNO 0 0
I WAS WORKING ON THIS BUT COULDN'T GET THROUGH IT ANYTHING WOULD BE A BIG HELP FOR ME FROM YOU GUYS

Deleting Data By Comparing To Another Table
Jul 20, 2005I have an entry form allowing customers to enter up to 15 skus (productid) at a time, so they can make a multiple order, instead of enteringone sku, then submitting it, then returing to the form to submit thesecond one, and so forth.From time to time, the sku they enter will be wrong, or discontiued, soit will not submit an order.Therefore, when they are done submitting their 15 skus through the orderform, I want a list showing them all of those skus that came back blank,or were not found in the database.I'm doing this by creating two tables. A shopping cart, which holds allthe skus that were returned, and a holding table, that holds all theskus that were submitted. I want to then delete all the skus in theholding page that match the skus in teh cart (because they are goodskus) which will then leave the unmatched skus in the holding table.I'll then scroll out the contents of the holding table, to show them theskus that were not found in the database.(confused yet?)So what I want to do is have some sql that will delete from the holdingtable where the sku = the sku in the cart. I've tried writing this, butit dosn't work.I tiried this delete from holding_table where sku = cart.skuI was hoping this would work, but it dosn't. Is there a way for me to dothis?Thanks!Bill*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Columns of table_one and table_two are: name ,ssn

If i compare ssn field from table_two and ssn in excelsheet_one, if it matches, the flagbit in excelsheet_one should say "T2".
Ex:
Table_one (input) ---- excelsheet_one ( Output)
ssn name ---- ssn name flagbit

Both the tables refers same excelsheet_one and have to update the same flag bit column in excelsheet.
Basically, i want to compare table and excel sheet, then if it matches, then update excel sheet.
Does anybody how to do this.

T-SQL (SS2K8) :: Comparing Column Values In Same Table
Jun 16, 2014How to resolve the below task
create table #temp ( idx int identity(1,1), col1 int, col2 int )
Here i want a flag success or fail on basis of below conditions.
I need to take all the col1 values and then i need to compare to each other.
if any difference found, i need to check difference more than 30, then it should raise the flag as "Failure".
if all the col1 values are ok , then we need to check Col2 values same as above.
--case 1
insert into #temp(col1,col2)
select 16522,18522
union all
select 16522,18522
union all
select 16582,18522
--select * from #temp
--truncate table #temp
Because of difference in col1 values . the value of flag should be fail.
--case 2
insert into #temp(col1,col2)
select 16522,18522
union all
select 16522,18522
union all
select 16522,17522
Here also the col1 is ok but col2 values have difference so it should be Fail.
Otherwise it should be success.

SQL Server 2008 :: Comparing / Merging Records In Single Table?
Jun 2, 2015I'm trying to avoid a large amount of manual data manipulation.
Here's the background: Legacy system that has (well let's call apples apples) pretty much no method of enforcing data integrity, which has caused a fairly decent amount of garbage data to be inserted in some tables. Pulling one of the [Individuals] table from within this Legacy system and inserting it into a production system, into the Table schema currently in place to track [Individuals] in this Production system.
Problem: Inserting the information is easy, how to deduplicate the records that exist within the staging table that the legacy [Individuals] table has been dumped into in production, prior to insertion. (Wanting to do this programmatically with SQL or SSIS preferably, so that I can alter it later to allow for updating existing/inserting new)
Staging Table Schema:
;
CREATE TABLE [dbo].[stage_Individuals](
[SysID] [int] NULL, --Unique, though it's not an index intended to identify the [Individuals]
[JJISID] [nvarchar](10) NULL,
[NameLast] [nvarchar](30) NULL,
[NameFirst] [nvarchar](30) NULL,
[NameMiddle] [nvarchar](30) NULL,
[code]....
Scenario: There are records that duplicate the JJISID, though this value is supposed to be unique for every individual. The SYSID is just a Clustered Index (I'm assuming) within the Legacy system and will be most likely dropped when inserted into the Production [Inviduals] table. There are records that are missing their JJISID, though this isn't supposed to happen either, but have valid information within SSN/DOB/Name/etc that can be merged into the correct record that has a JJISID assigned. There is really no data conformity, some records have NULLS for everything except JJISID, or some records will have all the [Individuals] information excluding the JJISID.
Currently I am running the following SQL just to get a list of the records that have a duplicate JJISID (I have other's that partition by Name/DOB/etc and will adapt whatever I come up with to be used for those as well):
;
select j.*
from (select ROW_NUMBER() OVER (PARTITION BY JJISID ORDER BY JJISID) as RowNum, stage_Individuals.*, COUNT(*) OVER (partition by jjisid) as cnt from stage_Individuals) as j
where cnt > 1 and j.JJISID is not nullNow, with SQL Server 2012 or later I could use LAG and LEAD w/ the RowNum value to do my data manipulation...but that won't work because we are on SQL Server 2008 in this environment.
[URL]
With, the following as a potential solution:
GSquared (3/16/2010)Here's a query that seems to do what you need. Try it, let me know if it works.
Performance on it will be a problem, but I can't fine tune that. You'll need to look at various method for getting this kind of data from the table and work out which variation will be best for your data. Without access to the actual table, I can't do that.
;
WITH CTE
AS (SELECT master_id,
MIN(ID) AS first_id,
MAX(Account_Expiry) AS latest_expiry
FROM #People
GROUP BY master_id)
SELECT P1.master_id,
[code].....
Unfortunately, I don't think that will accomplish what I'm looking for - I have some records that are duplicated 6 times, and I'm wanting to keep the values within these that aren't NULL.
Basically what I'm looking for, is to update any column with a NULL value to the corresponding Duplicate [Individuals] record value for that column.
**EDIT - Example, Record 1 has a JJISID with NULL NameFirst & NameLast BUT Record 2 has the same JJISID and values for NameFirst & NameLast. I'm wanting to propogate the NameFirst & NameLast from Record2 into Record1
Transact SQL :: Comparing 2 Records / Multiple Instances In The Same Table For A Specific Combination?
Jun 10, 2015I have a problem where I have 2 compare 2 records from the same table. This part looks easy but the problem is for a User there can be multiple records and I have 2 compare each record with its previous instance based on the timestamp. Not only I have to compare I have to perform some analysis. Below is the Table script and sample output.
Givens: All SQL Server 2008 or 2012 tools at your disposal.
Production database contains the following tables (simplified for example: constraints ignored, etc.) associated with a racing video game’s server.
-- A player of our game
-- Table greater than 10 million rows
CREATE
TABLE [dbo].[User]
(
[UserId]
[bigint] NOT
NULL
,[country]
[int] NULL
-- User’s home country
,[name]
[nvarchar](15)
NULL -- User’s displayable name (‘John’, ‘Bill’)
,[subscriptionTier]
[int] NULL
)
-- 0 == free, 1 == paid, for instance
Assume that rows get written into the event tables at a rate of 1,000 a minute,are never updated once written and currently are only read on a replica/reporting server.
Question Background: Write up a single query that would return the following: List of users and whose “TotalMoneyEarned” value ever grew (between logon events) at a rate of more than 1,000 per minute (we’d consider these suspicious and flag them for later investigation).
For instance, if the sample data were:
-- example of [Events.UserLogon] data -- not the query output we want
EventId UserId TotalMoneyEarned LogonDate
----------- -------------------- ---------------- -----------------------
1 1 1000 2010-10-16 00:19:56.460
2 1 1500 2010-10-16 00:20:56.460
3 1 3000 2010-10-16 00:21:56.460
4 1 10000 2010-10-16 00:29:56.460
Event 1 is okay because there’s nothing to compare it against
Event 2 is okay because the TotalMoneyEarned only grew 500 in a minute
Event 3 should be flagged, as the value grew 1500 in a minute
Event 4 is okay, as it grew 7,000 in 8 minutes (< 1000 per minute)
Query Output (your query should return data in a format like this):
User Flagged Logon Time Rate Since Last Logon (money/minute)
John 2010-10-16 00:21:56 1500
Dave 2010-10-16 00:30:50 3200
Bill 2010-10-16 00:35:23 1000
It is likely that you will need to create sample data for both the User and [Events.Logon] tables. We are looking for a single query that returns data like what is represented in Query Output.
FileGroup Structures
Apr 14, 1999I have 2 test database identical in size and table structure, only one resides on filegroups and one resides on a single file.
From everything I have heard filegroups are suppose to improve performance. I stop and start the server before each test to clean out
cache. When I run the filegroup test initially the first run averages 20 seconds slower then the database sitting on the single file. However
on consective runs there is a significant improvement in performance with filegroups verses single files. I have
the indexes sitting on a separate filegroup and 2 additional filegroups to spread the tables across. Does any one know what would be causing
the performance to degrade on the initial run of the test. (The test by the way is a stored procedure that runs a select statement against each table).
Any Info Will help Thanks

But something a Foreign Key from ParentID references (Id) with the delete-Rule on cascade seems not to be possible, because of multiple cascade Paths or cycles. Do i have to add some xtra constarins:
Not Possible:
create Table tree (
Id varchar Not null,
ParentId varchar Not null,
Constraint pk1 Primary Key (Id),
Constraint fk1 Foreign Key (ParentId) references tree(Id)
On Update Cascade
On delete CAscade
)
Do i have to write triggers, which delete The subnodes too and set the Update-/deleterulr on NO Action
