Anyone Know Table Limits In Multi-schema Environment?
Mar 27, 2007
My product is growing rapidly and currently I have a db for each client with identical schema. Of course maintenance is pretty hard. I was thinking of using a shared db but having a schema for each client (sql 2005) - I have almost 100 tables in the schema which means with just 10 clients the db would pass 1000 tables. My gut is telling me this ain't going to fly!
any ideas? and if it does work ... any thoughts on updating the internal schemas for each client?
thanks

Disaster Recovery Options based on the following criteria.
--Currently running SQL 2012 standard edition
--We have 18000 databases (same schema across databases)- majority of databases are less than 2gb-- across 64 instances approximately
--Recovery needs to happen within 1 hour (Not sure that this is realistic
-- We are building a new data center and building dr from the ground up.
What I have looked into is:
1. Transactional Replication: Too Much Data Not viable
2. AlwaysOn Availability Groups (Need enterprise) Again too many databases and would have to upgrade all instances
3. Log Shipping is a viable option and the only one I can come up with that would work right now. Might be a management nightmare but with this many databases probably all options with be a nightmare.

I wanted to know if there's a limit on how many targets I can manage in Multi Server Administration.In addition, are there any known limits regarding managing SQL instances with different versions (SQL 2005,2008,2008R2 and 2012).

We are currently managing about 75 SQL Server instances. Each instance contains jobs (backups, index work, admin, etc) which report back to a central instance for monitoring. This is working well, but each time I need to change one of the jobs, I am having to log into each instance to do so.
I have recently played with Multi-server Environment, using a master and target, to see if this might help. There is relatively little written about Multi-server in books-online, and I am left with a question.
All jobs appear to be exact duplicates. But I don't want exact duplicates. For example, on the various target servers, I would like for the backup jobs to run at different times, and write to different directories. How are the rest of you working around this situation, if you are using Multi-server Environment?

My company uses a quad processor server connected to a SAN to load and summarize detail sales information from 2000 stores on a nightly basis. We poll and load around 5,000,000 rows of data each night. THis information is summarized up to various levels, then replicated to one or more secondary datamart servers for end user access via web reporting, BI tools like Proclarity/Analysis Services etc...
The initial data polling server is only touched by the development staff supporting the process (1-5 programmers) and is licensed for SQL server Enterprise using a CAL model. Each datamart server is licensed with MS SQL server processor licenses.
The question: We were told that the quad processor polling machine, which has no end user access allowed, must be licensed with processor licenses since it touchs the data ultimately consumed by end users. This makes no sense to me.
The Microsoft white papers discussing multi_tier environments don't seem to address this type of issue. They focus on applications that ultimately pass thru a data request to the SQL server machine. In this situation, user requests are handled by the datamart servers, which are licensed with processor SQL licenses.
Can anyone clarify?
Thanks, Mike

I am currently working on a project in which I am using SqlTransaction objects with their IsolationLevel set to Serializable. I am wondering what would be the effect if multiple threads were to call this code at the same time? Would the second transaction (created by the second thread on the same connection), for example, be queued until the first one (created by the first thread on the same connection) finishes? Or would an exception be thrown for the second transaction? In case an exception is thrown, would using the synchronization (locks) around critical sections solve the issue?
I guess it is easier to understand the scope of transactions in terms of multiple users, but it is confusing (for me) when I start thinking in terms of multiple threads. The underlying data is held in a single table and the scope of the transaction spans multiple SELECTs and an UPDATE or an INSERT.
I have been trying to find a feasible answer, and haven't found anything credible yet. Help!

Hi,
I am developing reporting application (access project) which will be used in multi user environment.
Here is what I have:
1 SQLServer database for many users
Each report will be based on:
stored procedure which creates a table filtered for specific dates predefined views will use the newly generated table to show results to the client. However, if more than 1 person runs reports results will not be accurate if each person specified different dates because they will look at the same table and results will match only for a user who called the stored procedure last.
what can you recommend - how to report in multi user environment?
Many thanks

Hi!
In my database I have all business logic in stored procedures. For example there are procedures: ReadBike and UpdateBike. Bike is business object stored in 4 tables.
On my system work 100 employees and we have one problem with this. The stroy is;
1. User A reads data about Bike1
2. User B reads data about Bike1
3. User A updates data about Bike1 (user B have old data)
4. User B updates data about Bike1
So user B don't know about chnages made by user A. How to solve that ptroblem?
It's probably solved in ADO, but I want use business login in procedures.
Regards,
Walter

I was wondering if you guys might give me some advice on how best to handle a particular scenario i'm struggling with.
I have a client that basically wants web-based-update access to their sql server database. Specifically, for a group of users to be able to access a page where they select a record for editing. the caveat is that no two users should be able to pull up the same record at the same time. Originally I would have thought there was some easier record-locking-mechanism I could exploit within sql server or ado.net itself, but I haven't been able to come up with anything.. so this is my current approach:
The page they use starts-out with basically a blank form. there are custom-built paging controls at the bottom of the screen. they click page-forward to begin and a stored procedure is ran to select a record and update a field on that record to indicate "in-process". when they finish editing the record - or page on to the next record without updating - another stored procedure is ran - updating/resetting the status field on the record appropriately.
The entire page is encapsulated within an ajax.net updatepanel.
The entire page has caching disabled. This works well in conjunction with the first page being blank. if they get out of the app and try to get back in by clicking the back button - all they can do is get to the first (blank) page.
A piece of javascript window.onunload clicks a button on the page that releases the record they currently have selected in the event of a re-direct, clicking back, etc.. it appears to work with everything except a window close. in that case, i have a stored procedure running periodically on the server that checks how long a record has been selected - and if it exceeds the time indicated - resets the record as to allow it to be re-selected later.
In the event of session timeout, they are redirected to another page that tells them their session has timed-out (and since the window.onunload fires - it takes care of releasing the record if they have one on the screen).
The concept seemed to be working well until I started multi-user testing. Now it seems as if two users time it perfectly - they are actually able to both select the same record. it happens pretty rarely, but it does seem to happen. I'm guessing this has to do with how my stored procedure is structured - possibly allowing a tiny-enough window between the record being selected for editing - and the update running to actually status the record as in-process (2 separate sql statements within the one stored procedure).
I believe I also have a found a second quirk in my approach where something is causing the window.onunload event to fire twice in some strange situations.. but that's more annoying/confusing from a logging standpoint than anything..
I've read where people say to ensure you dont update a record that's already been updated - that you should compare the fields before you actually perform the update and ensure they haven't changed since you selected it.. but to me that doesn't solve anything.. if two people select the same record and both spend time working on it - the person that tries to update last has just wasted their time.
I've also toyed with the idea of maintaining a separate table in the database to hold the keys to the currently selected records and use that to keep multiple people from selecting the same record - but honestly i dont know if that approach is any better than what i'm doing now.
anyway, I was just curious if you guys had any advice in regards to how you'd handle a request like this.. or if you see any obvious problems/fixes with my current approach..
I would greatly appreciate any info you could provide-
thanks-

Hello--
Is it possible to install/configure SQL-Server 2005 on a multi-processor machine so that the relational DB utilizes a given subset of processors while Analysis Services utilizes another subset?

I am setting up sharepoint and sql server integration environment. I am considering the following topology: PowerPivot for SharePoint 2013 and Reporting Services in SharePoint mode Two Server Deployment
[URL]
I am looking to follow the topology example by the letter, which involves installing PowerPivot for SharePoint (aka SSAS in SharePoint mode) in the same server as my SQL, and installing SSRS in SharePoint (SP) integrated mode in the same server as SharePoint.
I understand, however, that if I wanted to install SSRS in SP mode in the same server as SQL, I could but only if the server contains the SP Object Model.
My first question is, what would involve having the SP Object Model in the SQL Server?
Would only installing SP binaries be enough; or Do I need to do a minimal install of SP in the SQL server enough for it to joing the SP farm? And most importantly, what would be the licensing implications for SP in case I want proceed down this route and have SSRS in SharePoint mode installed in the same server as the SQL?

I am currently building an application that will host multiple clients in the same database. Each client will have their own schema. Common data will be stored in [dbo] tables commonly accessible. Client data will be stored in matching schema-specific tables.
EX:
[ClientA].[Orders] ...
[ClientB].[Orders] ...
[ClientC].[Orders] ...
So far so good.
Upon issuing select statements under the various logins, the proper table is accessed and improper tables are protected.
The problem comes when working with the various stored procs to access the data.
My original though was that I would have one version of the stored procs and they would be calling-schema aware, much like select statements are, and deal with the proper table data. What seems to be the case is that each client needs its own copy of ALL the stored procs, creating a maintenance nightmare considering each client's procs is identical in EVERY SINGLE WAY except for the owning schema.
It seems once a proc is called the ownership chain changes to the proc's schema and ignores the caller from there on out. Am I missing a step in this or do I have the proper understanding (and problem).
Example:
Attached is a sample database script.
Four (matching) tables. Stored proc for accessing data via a table function. Three logins dealing with various iterations:
login: clienta
setup: Entry point proc set, table function missing (will call dbo version)
result: Permission error on call to table function. Fix that and pulls data from dbo table
login: clientb
setup: Entry point proc using dbo, schema-specific table function set
result: Calls dbo version of function (not schema version) and pulls dbo table data
login: clientc
setup: Entry point proc set, table function set
result: Correct data pulled from schema table
login: db owner login
setup: Both dbo proc and dbo function set
result: DBO table data pulled

I have designed a datawarehouse and I have
tremendous doubt about SQL 7.0 capabilities.
I expect to receive more than 20.000.000 into
a single table and to be honest I do not know if
I will get a reasonable query-response time.
My Server is a Toshiba Lince with a 500 Mhz processor
and 256 Mb of RAM memory. My hard disks are IBM ones.
Can anybody say me something?
Thank you in advance.

I have a database hosted by GoDaddy. Recently they made some changes to the interface and upgraded to SQL Server 2008. One or the other has made it impossible to access my data in one table.
The table is quite large in terms of the numbers of elements. Each row describes a dog and all the elements are components of the description. There are (I would guess) more than 50 elements all together.
When I try to search the database, the query form goes beyond the top and bottom of the page. I can scroll the database but the search tool (which lies atop the data) does not scroll. The result is that I can't activate the search.
I've tried about 10 machines. All with IE6 display this fault. Machines with IE7 do not. I've tried various screen resolutions on the machines with IE6. That doesn't help.
I've checked other tables in the database. No problem.
In short, there's nothing I can do. I can't edit my data and GoDaddy says, "Tough."
Is there a limit on the number of columns (elements) in a table in SQL Server 2008?

I have a table that I'm loading as part of a control flow that in turn is copied to a target table by using a data flow task. I am doing this because a different set of fields may be used from the source entry to create the target entry based on a field in the source table. That same field may indicate that multiple entries need to be created in the target table from one source table entry for which I use a multi-cast transformation.
The problem I'm having is that no matter how many entries there are in the source table, the OLE DB Source during execution only shows 7,532 entries being taken from the source table. If there are less than 7,532 entries in the source table, everything processes fine. More than 7,532 and the data flow task only takes 7,532 and then seems to hang. It also seems as though only one path of the multi-cast transformation is taken when the conditional split directs a source entry down that path.
Seems like a strange problem I know, but any insight anyone could provide is appreciated. Thanks.

I’ve got a situation where the columns in a table we’re grabbing from a source database keep changing as we need more information from that database. As new columns are added to the source table, I would like to dynamically look for those new columns and add them to our local database’s schema if new ones exist. We’re dropping and creating our target db table each time right now based on a pre-defined known schema, but what we really want is to drop and recreate it based on a dynamic schema, and then import all of the records from the source table to ours.It looks like a starting point might be EXEC sp_columns_rowset 'tablename' and then creating some kind of dynamic SQL statement based on that. However, I'm hoping someone might have a resource that already handles this that they might be able to steer me towards.Sincerely,

we have a table in our ERP database and we copy data from this table into another "stage"Â table on a nightly basis. is there a way to dynamically alter the schema of the stage table when the source table's structure is changed? in other words, if a new column is added to the source table, i would like to add the column to the stage table during the nightly refresh.

Hello,
I'd like to create a temporary table with the same schema as an exiting table. How can I do this without hard coding the column definitions into the temporary table definition?
I'd like to do something like:
CREATE TABLE #tempTable LIKE anotherTable
..instead of...
CREATE TABLE #tempTable (id INT PRIMARY KEY, created DATETIME NULL etc...
I'm sure there must be a simple way to do this!
Many thanks,

I have a new production server with about 100 jobs on it. These are ETL jobs about half of which are in SSIS packages and half call stored procedures directly. For those calling stored procedures directly, might there be a way to use the system catalog to link the schedule of the job to the table being updated by the procedure? The result is a list of tables (those updated by jobs) and the schedule of when they are updated.

Hey,
I'm looking at creating a table in a stored procedure
[declare @tempTable table]
however, rather than then declaring the tables schema
[declare @tempTable table (pkField IDENTITY (1,1), SomeOtherField varchar(50), ...)]
I'd like it to simply use the schema of an already existing table (plus an additional column).
Is there a way to do this without having to manually write the table schema?
A simple example is:
I have a table
OriginalTable (idCol, NameCol, InfoCol)
I'd like to create a temp instance of that table called tempTable which would have a final schema of
tempTable (idCol, NameCol, InfoCol, myTempCol)
The reason I'd like to do this using the schema is so that I don't need to update all my procedures in the future when we decide to add some more detail to the originaltable which needs to be selected as well.
Thanks a lot for any help or direction you can provide.

I have a problem, in one of my db's I have a table tblpersons in schema web the rest of the table's in the db are in schema dbo. Now I removed the user web, but I want to change the schema of tblpersons from web.tblpersons to dbo.tblpersons. I created a stored procedure with the line " ALTER SCHEMA dbo TRANSFER web.tblpersons", when executing this I get an error that the table tblpersons couldn't be found.

We currently have all tables in the dbo schema, but for organizational reason we would like to split them up in multiple schemas and I wonder if that can be done without re-creating the tables.
So my question is, is there a way to move a table into a different schema without re-creating it? (For those familiar with Postgres I'm looking for an equivalent to "ALTER TABLE foo SET SCHEMA newschema") sp_rename only allows a "one-part name" for the new name, so apparently that cannot be used.

I have created a table on SQL Server from SAS. The table gets created fine. However, the table schema has my user ID in it (AD-ENTmyuserid.Table1). How can I change the schema to dbo.(dbo.Table1)? It's fine if I have to make this change in SQL Server Management Studio.

I am more familiar with writing SQL for Oracle than MS SQL Server. Within Oracle there is a simple command, 'Describe', which actually shows the data types, and whether or not an attribute accepts NULLS. MS SQL Server does appear to support such a command, however I am looking for a way to describe the attributes of tables nonetheless.

Hi,
I am a bit confused and wish to share this with you for help. We are designing a billing application to bill telephone calls. It currently handles a single rate plan. So what it does is that it looks up the RATES table and matches the called number area code with the RATES.ACCESS_Code field to find the tariff for that area and multiplies that by the number of minutes. Here is the current schema.
CALLS
•ID (pkid)
•Called Number
•Duration
RATES
•Destination Name
•Access_Code (pkid)
•Tariff
Now the problem is that we need to process calls based on RATES per OPERATOR. Each operator is a telephony carrier with similar RATES. However, each call will be prefixed with a number to indicate which operator carried that call. Accordingly, the database should relate that prefix with the proper operator and then looks up the RATES that are related to that operator.
In conclusion we will have a replica of the RATES table for multiple operators. An operator is only supposed to have two fields I guess (name and ID).
So now we need to re-engineer the schema to adapt to this situation.
Eg. 95004433313445 (Will be identified as BT operator)
93004422376234 (Will be identified as AT&T operator)
Can anyone help please?
PS: we are using SQL Express 2005
Thanks
