I have 4 tables with the respective amount of records 1) 6755 2) 2021 3) 2021 4) 355
They all have the same columns. However, they need to be seperate, or at least when I query them. I'll be accessing this database via the web. i was first afraid that a large database would cause major slow down when accessing the db. So I broke it up into 4 tables. If I combined all 4 tables into one large table and just had a column that differentiated the 4, how significant would be the change in speed when accessing the table? It's not a big deal to keep them seperate, its just that when I have to add or remove a column from one table I have to remove it from all the tables. Furthermore, I'm using a module from DEVEXPRESS, don't know if anyone has heard of it, but when you use a gridview, it loads up the entire table even though your paging (which I think is retarded), so for that reason I was afraid it would slow up my access to the db. Any thoughts?
I want to produce some output for Mainframe application. For that I want to insert values from multiple table as source to a single column (huge in size)of a different table (Destination table). There may be same related records in all of the source tables with the primary key. When I export values from the source tables , each related records should be insterted to the destination table's field (multiple entries for each table). Please advise.
I have two table, tblCharge and tblSentence, for each charge, there are one or more sentences, if I join the two tables together using ChargeID such as: select * from tblCharge c join tblSentence s on c.ChargeID=s.ChargeID , all the sentences for each charge are returned. There is a field called DateCreated in tblSentence, I only want the latest sentence for each charge returned, how can I do this? I tried to create a function to get the latest sentence for a chargeID like the following: select * from tblCharge c join tblSentence s on s.SentenceID=LatestSentenceID(c.ChargeID) but it runs very slow, any idea to improve it? thanks,
My boss has asked me to look into this and I haven't been able to find any information on the web. I hope someone can answer this for me. We currently have a single database that is storing all the user information and transactions. Within the same database we are also logging different types of user activity. If both these tables are heavily used, would it make sense to separate it into different database, one for data and one for logging? Is there any pro or cons of having more than one database? Any opinion or suggestion would be greatly appreciated. I'm the closest thing they have to DBA and I'm really new to this. Thanks.
Does anyone have any idea how to syncronise two SQL identical tables acrossa network, between servers?We want to run our website from a SQL tables on the same server, but set upso that if the main SQL tables across the network change, or the tables onthe web server change, the two seperate servers willsyncronise/update/trigger updates to the tables on each other?We are running SQL server 2000.AHAJohn
Hi folks, I've got a fairly easy one here me thinx. I'm looking for the best way to compare two entire rows from two seperate tables which have the same primary key.
Here's the basic lowdown:
I get some data every night from an external system (cache') via DTS. This is more or less my "master" data which drives my application. I have just been informed of an interesting constraint. If any of the data changes in the external system, those changes do not become effective until the first day of the ensuing fiscal quarter.
I'm solving this by running the DTS as normal, but populating a "duplicate" table which I will evaluate once per quarter for any changes. This is also the preferred solution because they would like to see a snapshot between current cache' data and the data my application is currently working with.
So, I end up with two identically structured tables. both tables have the same primary key and can be linked by an id field with relative ease. What I would like to do is a full row comparision once this join is established.
Right now I explicitly check the value of each column. ie:
WHERE t1.field1 <> t2.field1 OR t1.field2 <> t2.field2 OR t1.field3 <> t2.field3 ... etc
I'm hoping there is something buried in TSQL that I just don't know about that can handle comparing entire rows and tell me if they're different. Or perhaps there's another approach all-together.
I have two databases in sql server. I'll call them DB1 and DB2. I have a table in DB2 that needs to form a relationship with a table in DB1. When I attempt to add a relationship I only see tables in DB2. Can this be done?
Hi! I have a big database which need some separation in multiple filegroups.
Therefore I plan to move tables to new filegroups. As I can understand this must be done by dropping the clustered index and recreating it on new filegroup, then data will move.
1. best way to get a list of all clustered indexes (sys.indexes)? 2. how to get index scripts? (using SSMS, right click is manual task, but I need scripts for than 100 tables) 3. when having the scripts it should be easy to replace filegroup part 4. after movement: just shrinking old files?
Hi there,I have tables with such structuretransaction_YYMM(idx,date,company_id,value)where YYMM stands for 2digits year and monthI want to define query (maybe view, procedure):select * from [???] where date>='2007-01-01' and date<='2007-04-30'which will grab data fromtransaction_0701transaction_0702transaction_0703transaction_0704and return all as onebest regardsRafal
Hello. I just created separate tables for each of my categories and wanted to know how to return them all to be viewed on one page using the SQL Datasource (or whatever) This is for user accounts. I just need to know that part. Sincerely, Computergirl
I am TRYING to write code to combine two tables and then return the maximum value of one table, but SQL Server keeps telling me that the column is not valid.... I have added attached screenshots to show that it IS a valid column, so I cannot figure out what is the retarded issue!!
I have two tables that share a common identity row. I need to build a query where data that exists in one table does not contain data in the other table. For example, table 1 has columns of Owner_ID, LastName, FirstName and table 2 has columns Auto_ID, Owner_ID, AutoMake. Both tables are joined by the Owner_ID column. I need a query that provides all owners from table 1 who do not have an entry in table 2.
Here is the scenario, I have 2 stored procedures, SP1 and SP2
SP1 has the following code:
declare @tmp as varchar(300) set @tmp = 'SELECT * FROM OPENROWSET ( ''SQLOLEDB'', ''SERVER=.;Trusted_Connection=yes'', ''SET FMTONLY OFF EXEC ' + db_name() + '..StoredProcedure'' )'
EXEC (@tmp)
SP2 has the following code:
SELECT * FROM SP1 (which won't work because SP1 is a stored procedure. A view, a table valued function, or a temporary table must be used for this)
Views - can't use a view because they don't allow dynamic sql and the db_name() in the OPENROWSET function must be used. Temp Tables - can't use these because it would cause a large hit on system performance due to the frequency SP2 and others like it will be used. Functions - My last resort is to use a table valued function as shown:
FUNCTION MyFunction ( ) RETURNS @retTable ( @Field1 int, @Field2 varchar(50) ) AS BEGIN -- the problem here is that I need to call SP1 and assign it's resulting data into the -- @retTable variable
-- this statement is incorrect, but it's meaning is my goal INSERT @retTableSELECT *FROM SP1
Hey all, Here is what I would like to do.. if any can give some advice or direction with this i would appreciate it.
We have a "master database" (MS SQL) at our main office. Then a smaller office with only a dial-up connection. Can I have my db application write all the data input to a local DB. Then write something to connect with the master DB, through a Terminal server, etc., and update it with the data from the other smaller db?
I've got a customer who thinks their data should be sepeated and reside on two seperate databases in case one is compromised. Now I've never heard of anyone doing this and would like comments from the users here as to why this should/(shoult not) be done.
I'm assuming that they want to keep their general info e.g. name and address on one database and keep other (medical info) on the other db.
None of our db's are outside of the firewalls so to me this makes no sense but I would like feedback.
Hi, this is my first post to this forum so thank you all in advance..
I am trying to design a database to store information about the Specification required by each customer. And the main problem I am having is how to store 2 instants of ContactID (from CustomerContacts table) in a seperate table called CustomerSpec.
For example each Customer has many contacts,(the Customer data is stored in a table called Customers which has a one to many relationship with the CustomerContacts table) each customer has one and only one Customer spec, and each customer spec needs to have 2 customer contacts, ie. one for Artwork and one production. (it should also be possible to have the same contact for both Artwork and production).
The problem is how to associate these contactId's with the customer spec...(if there was only one Contact per spec I could simply link the CustomerContacts table with the CustomerSpec table and drop ContactID into CustomerSpec as a foreign key.. But I am stuck to how to save more than one ID..
I have a project were I will have it so that users can sign in and change information on an SQL server. The catch is that this site will be from a different domain name and from a different hosting company then where the SQL database is located. Sorry if this is a dumb question but how can I utilize asp.net to change and view an SQL database that is located else-where. For example: a user logs into www.something.com and he/she can view and edit SQL tables from www.somethingelse.com's database. Thanks in advance.
I'd like to create a view on server x which references tables on an entirely seperate server. Is this possible? Is seems strange to have to copy the tables over just to create a view. In the view wizard I can't seem to 'browse' to the tables on the other server.
The code I'm working with would conceptually be something like this:
select server name.database instance.owner.table.field
I'm trying to replicate a SQL join across two seperate data sources in SSIS. If I were to write SQL to do this, it would be as follows:
SELECT Costs.CostRateEntryId,
Costs.UserId,
Costs.HourlyRate * 8 AS DailyCostRate,
Dates.DateKey,
Dates.ActualDate,
FROM Costs
INNER JOIN Dates ON Dates.ActualDate >= Costs.EffectiveDate AND Dates.ActualDate <= Costs.EndDate
Unfortunately, as the tables 'Dates' and 'Costs' are in two seperate SQL2005 systems, I can't really do this. I was hoping that it could be achieved in SSIS, but I cant seem to find any way that I can do a join that's <= or >=.
Hello everyone, Here's my situation... I'm running a web service which involves 51 seperate servers and databases. There are fifty licensee servers (One for each US state) and one corporate server. Each night I need to upload sales and membership data from the licensee's databases to the corporate database to compile reports. The application platform I'm using is ASP.NET 2.0 and the the database is SQL2005 express. I want this process to be run automatically, so I believe it's a scheduled windows service I need to setup up in .NET to make the data transfers. If anyone has already set something up like this, or knows the steps to take? I would love to have your input. Thanks in advance, Robert
I have the following query:SELECT Month, Sum(Hits) AS Hits FROM tblHits GROUP BY Month ORDER BYMonthUnfortunately it only returns rows for months that have data assignedto them.How can I tweak this so that months 1-12 are returned, and Hits = 0 formonths with no data in the base table?Thanks.
I'm trying to insert data into a table from two tables into a single table along with a hard coded value.
insert into TABLE1 (THING,PERSONORGROUP,ACCESSRIGHTS) VALUES ((select SYSTEM_ID from TABLE2 where AUTHOR IN (select SYSTEM_ID from TABLE2 where USER_ID =('USER1'))),(select SYSTEM_ID from TABLE2 where USER_ID =('USER2')),255)
I get the following-
Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
What's the best way to convert a large set of records from a simple schema where all fields are in one table to a schema where fields are split across two tables? The two table setup is necessary for reasons not worth getting into here.
Doing this via cursor is pretty straightforward, but is there a comparable set-based solution?
Here are sample create table commands. Obviously, the example below is simplified for discussion purposes.
-- One record from here will produce a record in TargetParentRecords and a record in TargetChildRecords for a total of two records. CREATE TABLE OriginalSingleTableRecords ( ID INT IDENTITY (1, 1) NOT NULL,
ColumnA VARCHAR(100) NOT NULL, ColumnB VARCHAR(100) NOT NULL,
i have to transfer data from one table to three other new tables. and if there are any duplicates in original table i have to send them to duplicates table.the remaining data should be send to three other tables. so can anyone help writting stored procedure for this.
i have using BCP to output SP return data into txt file, however, when it return nothing , it give SQLException like "no rows affected" , i have try to find out the solution , which include put "SET NOCOUNT ON" command before select statement, but it doesn't help :(
anyone know how to handle the problem when SP return no data ?
I have multiple tables with information about a user. The tables are Roles, Users, Groups and Profiles.
For a user session I need information from all those tables. Would it be better to make a table called UserSession and collect the necessary data from the above mentioned tables and stick them in one the UserSession table or should I just write a query that goes out and gets the data from the different tables.
I have a table, dbo.Table1(Id,Col1,Col2,Col3,Col4,Col5,Col6,Col7,Col8) that I need to split between two tables dbo.Table2(Id, Col1, Col3, Col4) and dbo.Table3(Id,dbo.Table2_Id,Col5,Col6,Col7,Col8). But in dbo.Table3 I need to have the Id column from dbo.Table2 populated since its a foreign key constraint in dbo.Table3. How do I go about doing this?
