DB Table With 1000 Columns?
Feb 15, 2008
I was wondering if it is possible to have a DB table with 1000 columns?
The other way is of course to break these columns into 1000 rows and an ID which tells what exactly does it relate to.
I want to know the pros and cons of having 1000 columns/rows for one set of related data.
The reason to need 1000 columns in the first place is that there are about 1000 questions in a set whose answers need to be saved for one session (hence all should go together).
Can anybody shed some light on it? Has anybody tried something so crazy before?

We just switched from Sql server 2008R2 to Sql server 2012.I am facing one problem with identity Columns "When ever i restarts my sql server,the seed value for each identity column is increased by 1000 (For int identity column it is 1000 and for big int it is 10000).
"For Example if seed value of any table was 3 then after restarting sql server will be 1003 if i again restart sql server it will be 2003 and so on."
After searching on google i found that it is a new feature (don't know what is use of it) in sql server 2012 and having only two solution if you want old identity concept
1. Use sequence object -
a) I am using same database in sql server 2008 and 2012 both so can't use sequence in 2008.
b) if i go with sequence then need not change save procedure for each table,which is bulky task for us.
2. Use Trace Flag 272 (-T272)
I can go with this solution because there is need not do any changes in my application.Some one suggested me that add -T272 in startup parameter,after this sql server identity column will work normal as previous version.I did the same but it is not working.
I don't want to do any changes in my database structure.
how to use this -T272 or why it is not working.
I don't want to use this new identity feature how to suppress it. Why -T272 is not working.

Hi,Currently we're a building a metadatadriven datawarehouse in SQLServer 2000. We're investigating the possibility of the updatingtables with enormeous number of updates and insert and the use ofcheckpoints (for simple recovery and Backup Log for full recovery).On several website people speak about full transaction log and thepace of growing can't keep up with the update. Therefore we want tocreate a script which flushes the dirty pages to the disk. It's notquite clear to me how it works. Questions we have is:* How does the process of updating, insert and deleting works with SQLServer 2000 with respect to log cache, log file, buffer cache, commit,checkpoint, etc?What happens when?* As far as i can see now: i'm thinking of creating chunks of data of1000 records with a checkpoint after the Query. SQL server has thedefault of implicit transactions and so it will not need a commit.Something like this?* How do i create chunks of 1000 records automatically withoutcreating a identity field or something. Is there something like SELECTNEXT 1000?Greetz,Hennie

I have a table set of records. Its contains some customerID,SportsGoods,Price in different datetime. I want to add customer spent. If crossed 1000 means i have to show purchase time when it is crossed 1000. I need query without while and looping.

Im trying to upload 1000 txt files into one table in SQL. I'm using the following query, to upload one txt file at a time:
bulk insert [dbo].AAA_2013_2015
from 'dataserverSQL Data FilesSQL_EMELIZFC x Bloque Detallada201308 Detalle FacturasFACT_BLOQ_AGO13 (4).txt'
with (firstrow = 2,
lastrow = ???,
fieldterminator = ';',
rowterminator = '0x0A')
I'm trying that the query skip the last row because gives me the following error:
Msg 4866, Level 16, State 1, Line 1
The bulk load failed. The column is too long in the data file for row 1, column 17. Verify that the field terminator and row terminator are specified correctly.
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.
Msg 7330, Level 16, State 2, Line 1
Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".
know a command to skip the last row, something like lastrow= all-1...or something like that.
I also executed using MAXERRORS command...like this:
bulk insert [dbo].AAA_2013_2015
from 'dataserverSQL Data FilesSQL_EMELIZFC x Bloque Detallada201308 Detalle FacturasFACT_BLOQ_AGO13 (15).txt'
with (firstrow = 2,
fieldterminator = ';',
MAXERRORS = max_errors,
rowterminator = '0x0A')
does not recognize MAXERRORS command, also tried to put a number of error instead of max_errors.

I am using SQL SERVER 2008R2, not Denali, so I cannot use OFFSET FETCH Clause.
In my stored procedure, I am doing a SELECT INTO #tblTemp FROM... Working fine. This resultset is going to be used in an SSIS package which will generate a pipe-delimited .txt file... Working fine.
For recoverability sake, I am trying to throttle back on the commit chunks to 1000 rows per commit until there are no more rows. I am trying to avoid large rollbacks.
Q: Am I supposed to handle the transactions (begin/commit/rollback/end trans) when the records are being inserted into the temp table? Or when they are being selected form the temp table?
Q: Or can I handle this in my SSIS package for a flat file destination? I don't see option for a flat file destination like I do for an OLE DB Destination (like Rows per batch, Maximum insert commit size).

I have a sql snippet from a 3rd party application that will not complete its transaction. The SELECT statement executes but does not finish. Instead the statement just sits in AWAITING COMMAND for 1000 seconds then dies, thus killing the UPDATE statement that is supposed to follow.
The CROSS JOIN and CROSS APPLY seem suspect.
(
@p0 DATETIME,
@p1 INT,
@p2 INT,
@p3 NVARCHAR(4000),
@p4 INT,

So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.

Hi,
I have two tables
Table Source
{
category varchar(20),
LastUpdate datetime
}
Table Destination
{
SubjectId varchar(20),
SubjectDate datetime,
category varchar(20),
LastUpdate datetime
}
Please note that the number columns are different in each table.
I wanted to dump the data of Source table to Destination table. I meant to say that the rows of 2 columns in Source table to last 2 rows of Destination table.
And also my oreder of the columns in Destination table will vary. So i need to a way to dynamically insert the data in bulk. but i will know the column names for sure before inserting.
Is there anyway to bulk insert into these columns.
Your quick response will be appreciated

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below) and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.

Here is My requirement, I'm not sure if this is possible. Creating table called master like col1, col2 col3, col4 , col5 ...Where Col1, col2 are updatable - this can be done easily
Col3, col4 are columns in another table but these can be just a read only ?? Is this possible ? this is possible with View but not friendly with share point CRUD...Col 5 is a computed column of col 2 and col5 ? if above step can be done then sure this can be done I guess.

I have been given a Product table whoes all column types are varchar(8000)
One of the column is Price and other is DecimalPosition. Price column includes price without any decimal place and the data in DecimlaPosition column determins where the decimal should be placed.
So for instance, if the Price column includes '1000' and DecimalPosision includes '2' >> then it means that the actual price for this product is '10.00' and NOT '1000'. Similarly, if the DecimalPosision includes '3' >> then it means that the actual price for this product is '1.000' and NOT '1000'My question is that when I am getting the price for a product from this table, how can I get the price in the correct format, e..g like '10.00' and not '1000'Should I use SQL statements to convert 1000 into 10.00 or should I use some sort of programming logic to convert 1000 into 10.00.kind regards

I have started to install a 3rd party web-based product for our clients that uses SQL 2000 as its backend
However every time that they create a new 'topic' within the web app, it creates a new database, with a single table in it!! - There could/will be 1000's of these 'topics' created
I have told the company we buy this from that this is not acceptable - they have asked why!!
Can anyone point me in the direction of preferably a Microsoft document that I can send to them, as just saying 'you just don't do it that way' isn't working and I can't find anything easily myself
Many thanks

I'm in the process of converting legacy DTS packages to SSIS. I need to populate a table that has more fields than the source file. In DTS I did this with an ActiveX script. How do I go about doing this within SSIS.
In the ActiveX script most of the fields were defaulted with either spaces or zeroes.
One of the Destination fields needs to be incremented by 1 for each new record inserted.
Any help would be appreciated.
Thanks,
Jeff

Ok some company has handed me this .xls file containing a 1000+ users -- their emails (which are to be their user names), and their passwords. Both are in plain text format. I want to add these users to the ASPNET_DB, with the condition that the passwords and userids are encrypted, as they are in the table.

[crossposted]Hi, I wonder if anyone might lend me a brain.I have a stock database to build that covers over 1000 products, whichmight be said to exist in around 50 product families.Obviously, just to be awkward all the types of stock will havedifferent attributes. So one product might be a tube withinside/outside diameter and length and another a T shaped cable joint.All I can come up with is a separate table for each stock type familyand store the table name and product code in the main stock table, so:Tables:ProdAProdBProdCStockStock attributes:ProdIdProdTableAmountDateetc..ProdA attribute:ProdIdAttributeXAttributeYAttributeZetc..Then use code to parse the table and product ID to select the correctquery to get the product details. BUT This seems awefuly inelegant andpotentially wrong so I'm loathe to continue down this route.Can anyone tell me the "right" way to do this, I feel sure it must bea classic db design exercise, but unfortunatly one they didn't teachus at University -- or maybe I was asleep...Thanks!

Ok, so I have a primary table that contains the count of a linked table. Since I can let the identity update itself, I should be able to insert the same values into the linked child table.
I need to put the same record in the child table 1000 (that's an arbitrary number, this will be programatically determined by the user) times.
I understand that I can do this:
INSERT INTO SomeTable (Cols) VALUES (vals)
GO 1000
However, I can't make this work when doing an ADO.NET ExecuteCmd. It doesn't like the Go 1000 part of it.
Does anyone have an idea how I can do this VERY QUICKLY without having to execute a separate insert for every item (or batch them)?
The number could be as high as 250,000 in the child table.
Thanks!

Enterprise SQL Projects
---------------------------
When Design is replaced with an Architectural Plan
The following post is intended as a starting point of some main concepts to consider when dealing with ent. sql projects. While it is not a direct question of any kind, it would interest people that are/or was involved in ent. projects and therefore have been troubled with similar problems.
Here is a quick overview of a couple main concepts when you have to deal with a Ent. Projects with 1000+ stored procedures.
DOCUMENTATION:
It is an absolute must to include 100% explanatory code on top of the sps.
FUNCTIONS:
Use functions to the maximum extent to reduce overal stored procedure complexity
a rule of thumb is to have 1 to 10, functions to sps ratio or simmilar.
TRIGGERS:
A lot to say about them that cannot be covered in this context
NAMING CONVENSION:
Your naming convension should be 100% pre-thought and designed, no mistakes allowed in this context as it will cause all stored procedures to be extremely difficult/impossible to browse.
a quick template could look as this:
sp
module name
underscore(_)
action (lower case)
noun (proper case)
For example:
spOrders_putOrderDetail
spMaintainUsers_deactivateUser
spReports_getZeroInventory
(quoted by: tmorton)
my addition to this would be something like:
sp< as a prefix is surtently an overkill when dealing with 1000+ sps and is not needed.
however a lot more complex naming strategies can be used, that will cause the project to be a lot more easy to maintain.

Hello,
It seems that there is some kind of limitation in SQL Server agent job log. For any job there is not more than 1000 rows of history. This can be seen with the following query:
SELECT j.name, count(*)
FROM sysjobhistory jh,
sysjobs j
WHERE jh.job_id = j.job_id
GROUP BY j.name
HAVING count(*) >= 1000;
How to modify the limitation? We really need more than 1000 rows.

Hi
I have an PL/SQL procedure @ Oracle database which extracts 10000 rows from a table and Now I have load all the 1000 rows into SQL 2005 tables.
I have extracted the data from oracle into DataAdapter/dataset , Now I want to load all the rows to SQL 2005 tables. Please help how I can load..
If I use insert statement everytime , it makes server busy and takes much time for 10000 inserts to complete(even using Procedure goes heavy since for every insert have to call this).
Is there any possibility that i can pass the REF Cursor / Dataset/dataAdapter into SQL stored so that inserts will have happen all together ??
Thanks in advance for ur help.

Iam attempting to generate files containing more than 1000 characters per line by outputting the results of a stored procedure via osql to a flat file. Osql (and isql) appear to force a newline after 1000 characters, even when specifiying a -w2000 parameter.
I have also tried to output the results of the stored procedure via DTS and this appears to do the same thing!
Does anybody know how to prevent osql (or isql) from forcing the newline?
