SQL Server 2012 :: Delete Large Number Of Records?
Sep 8, 2015I have the following scenario:
SQL database on SQL 2012
Large Production table 15 Million record
The table has 3 years of data
New monthly data is being added every month.
A New Monthly data is being loaded, checked and finally approved after 6 or 7 iteration before approval.Because of this iteration the monthly data set is being added then deleted then added then deleted few times.Because the table is big this process takes time, any thoughts on how to make the delete insert process faster.Keep in mind I cannot do much because it is a production table and is being access by other users to do other analysis.
Delete is done based on trx_date which is a year/month combo, like 201508.
The table has monthly sales by customer aggregated.
The table structure is:
CREATE TABLE [dbo].[Sales](
[batch_key] [int] NOT NULL,
[Company_key] [int] NOT NULL,
[customer_key] [char](22) NOT NULL,

Two Different Tables, Each With Identical Column Names... Query Help
Nov 18, 2005I have two different tables... one for all Staff, and another for all Temp Staff. I need both to output to a datagrid, and so I need to grab both tables from a SQL query to output to my datagrid, but I can't seem to get the logic right for it to work. Can someone give me some suggestions on why my results are blank when I'm running this query? I thought a simple join would allow both sets of identical column names to coexist in peace...SELECT TOP 100 PERCENT dbo.StaffDirectory.UserName, dbo.StaffDirectory.LastName, dbo.StaffDirectory.FirstName, dbo.StaffDirectory.Dept, dbo.StaffDirectory.Title, dbo.StaffDirectory.EMail, dbo.StaffDirectory.LocationFROM dbo.StaffDirectory INNER JOIN dbo.TempStaff ON dbo.StaffDirectory.Location = dbo.TempStaff.Location AND dbo.StaffDirectory.EMail = dbo.TempStaff.Email AND dbo.StaffDirectory.Title = dbo.TempStaff.Title AND dbo.StaffDirectory.Dept = dbo.TempStaff.Dept AND dbo.StaffDirectory.FirstName = dbo.TempStaff.FName AND dbo.StaffDirectory.LastName = dbo.TempStaff.LName AND dbo.StaffDirectory.UserName = dbo.TempStaff.UName AND dbo.StaffDirectory.MDNo = dbo.TempStaff.MDNoIs something wrong here? It just doesn't work =(Any suggestions would be really appreciated.Thank you

Regarding The Query To Save The Ids Of The Edited Names From Different Tables Into A Single Table.
Mar 8, 2008Here with the below query iam binding my gridview with industry name,company name,Plant Name,Group Name related to the IDs in Audit table.Select Aud.Ad_ID_PK,Aud.Audit_Name,Ind.Industry_Name,Cmp.Company_Name,Pla.Plant_Name,Gr.Groups_Name,Aud.Audit_Started_On,Aud.Audit_Scheduledto,Aud.Audit_Created_On from

Ad_ID_PK in (select Ad_ID_PK from Audits)
Now i want to edit these names.
when i click on edit in gridview these names will be filled into textboxes and when i change the names it should compare the name with particular tables and should get the Id of that and store in Audits table.
For example:
i have this data in my audits table:

2
2
1
Here Commercial83312 is ID of that Audit and 2,2,2,1 are the Industry,Company,Plant and group Ids for that particular audit.In the front end i can see the names of this particular IDs.
when i edit the industry name in the UI it must check the name with industry table and get the ID of the changed name and store it in audit table.
so the data may be changed in audits table as :
Commercial83312
4
2
2
1
so here the industry ID is changed
I need the stored procedure for this.

Transact SQL :: How To Return Number Of Records In Query As If TOP Was Not Used
Jul 21, 2015What I would like to do is to have a TSQL Select return the number of records in the Result as if TOP (n) had not been used. Example:I have a table called Orders containing more than 1.000 records with OrderDate = '2015/07/21' and my client application has a threshold for returning records at 100 and therefore the TSQL would look like
SELECT TOP (100) * FROM Orders Where OrderDate = '2015/07/21' ORDER by OrderTime Desc
Now I would like to "tell" the client that only 100 of 1.000 records are shown in the client application grid. Is there a way to return a value indicating that if TOP (100) had not been used the resultset would have been 1.000. I know I could create the same TSQL using COUNT() (SELECT COUNT(*) FROM Orders Where OrderDate = '2015/07/21' ORDER by OrderTime Desc) and return that in a variable in the SELECT statement or even creating the COUNT() as a subquery and return it as a column, but I would like to avoid running multiple TSQL's. Since SQL Server already needs to select the entire recordset and sort it (ORDER BY) and return only the first 100 the total number of records in the initial snapshot must somehow be available.
SQL 2012 :: Generating CREATE TABLE Scripts For Large Number Of Tables
Feb 11, 2014Other than right-clicking on each individual table in SSMS and generating a CREATE script, is there a simple way to generate CREATE TABLE scripts for tables within a given database?
Background: I have a bunch of tables in one database, and I would like to add tables to a second database that have the same names and basic structures of some of the tables from the first database.
I do not need to transfer any data from the tables, this is a seperate project that will use a similar data structure. I just want to generate the CREATE TABLE scripts for 30ish tables within the first database, and then I'll tweak the scripts as appropriate and run them against the new database.

Table Variables Vs. Temporary Tables - Need To Understand Something
Nov 5, 2007Hi all,
I had a problem in a stored proc when I was using table variables in SQL Server 2005. I fixed the problem by changing them to temporary tables. It works now but I really want to understand why I had to do what I did. Here's the situation:
Had a stored proc that cached quite a bit of data (100-200k records with 7 columns) into a table variable. Then, it looped through this and returned a result set. The table this procedure was querying, then caching, was highly transactional. After about 2 or 3 users were hitting the same area at once, the procedure locked. If there were no locks, it executed very fast. However, it usually timed out (due to this locking).
After researching, I see that your usually better off sticking with temp tables for large amounts of data - but the primary explanation I hear for this is that you can index it. However, it also seems that the temp table will perform read-locking as its an actual physical table, whereas the table variable will not. Therefore, because there's no locking and its entirely in memory, the table variable is often the better choice. This is confusing me though because the problem I was experiencing was some sort of locking - which I thought would have been less likely with table variables.
The only other thought I had is that the table variables (if there were several of them existing at once due to several users executing the same procedure), were causing some kind of memory limit to be hit, making the database wait until some more memory became available.
Sorry for the long post, but I'd really like to know if anyone else has had these issues and what the cause might be.
Thanks,
Mike

I Can't Understand The Meaning Of A Prediction Query
Jul 27, 2006Dear friends,
I'm reading Wiley's Data mining with SQL Server 2005... There are MANY things I can't understand about MovieClick example (Chapter 3).
I hope someone is going to help me with this troubles...
WARNING (1): I'm a dummy both with sql server and data mining.
WARNING (2): My English is not good at all.
Just two questions for now:
1) When I create the model to predict the number of bedrooms for homeowners, the book says to check BEDROOMS as Predictable... question: is it also an INPUT for the model, or PREDICTABLE only?
2) I'd like to keep this model (number of bedrooms.......) and make a prediction query.
- Query builder
- select case table -> Homeowners
- Drag the Customer ID column from the Homeowners table and drop it on the grid
- Drag the BEDROOMS column from the mining model and drop it on the grid.
- On the last row: Source=PredictionFunction, Field=PredictProbability
- Drag the BEDROOMS column from the mining model and drop it into Criteria/Argument
- Add (i.e.) 'Two or Three' to the field Criteria/Argument
I execute the query and I obtain many rows in a table with the following colums: CustomerID, BEDROOMS and Expression: WHAT DOES THIS MEAN?
WHICH INFO DO I GET FROM THOSE NUMBERS? WHAT CAN I LEARN FROM THEM?
Thanx a lot in advance, please help me!

Return Missing Records Over Multiple Tables. Query Challenge!
Mar 6, 2008I have received some data out of a relational database that is incomplete and I need to find where the holes are. Essentially, I have three tables. One table has a primary key of PID. The other two tables have PID as a foreign key. Each table should have at least one instance of every available PID.
I need to find out which ones are in the second and third table that do not show up in the first one,
which ones are in the first and third but not in the second,
and which ones are in the first and second but not in the third.
I've come up with quite a few ways of working it but they all involve multiple union statements (or dumping to temp tables) that are joining back to the original tables and then unioning and sorting the results. It just seems like there should be a clean elegant way to do this.
Here is an example:
create table TBL1(PID int, info1 varchar(10) )
Create table TBL2(TID int,PID int)
Create table TBL3(XID int,PID int)
insert into TBL1
select '1','Someone' union all
select '2','Will ' union all
select '4','Have' union all
select '7','An' union all
select '8','Answer' union all
select '9','ForMe'
insert into TBL2
select '1','1' union all
select '2','1' union all
select '3','8' union all
select '4','2' union all
select '5','3' union all
select '6','3' union all
select '7','5' union all
select '8','9'
insert into TBL3
select '1','10' union all
select '2','10' union all
select '3','8' union all
select '4','6' union all
select '5','7' union all
select '6','3' union all
select '7','5' union all
select '8','9'
I need to find the PID and the table it is missing from. So the results should look like:
PID
MISSING FROM
1
TBL3
2
TBL3
3
TBL1
4
TBL2
4
TBL3
5
TBL1
6
TBL1
6
TBL2
7
TBL2
10
TBL1
10
TBL2
Thanks all.
SQL 2012 :: Query With Three Tables?
Jul 22, 2015I currently have a query that uses three tables [Table1, Table2, Table3]. Each table only has two columns: Group and something else. I want a query that gives me the group and those three something else.
Table1: Group and Info1
Table2: Group and Info2
Table3: Group and Info3
Query: Group, Info1, Info2, Info3
The groups never repeat in a single table.
However, the groups are not identical in every table. I want the groups to never repeat twice: All the groups should appear if they are there at least once in one of the table, and provide Info1, Info2, Info3 (blank if it's not there in its table, filled if it is).
That should be a fairly simple query, I just can't seem to make it work so groups don't repeat.
Little visual example.
Table1: Group - Info1
1 - a
2 - b
4 - c
5 - d
Table2: Group - Info2
1- aa
3- bb
4- cc
Table3: Group - Info3
5- aaa
The query would give me this:
1 - a - aa - ""
2 - b - "" - ""
3 - "" - bb - ""
4 - c - cc - ""
5 - d - "" - aaa
