Price Of Using Multiple Databases In SELECT Statements
Sep 11, 2007
Hi,
We are discussing possible implementation for sql2005 database(s). This database will serve one web portal. Part of data will get into it by hand, and part will be replicated from internal system.
Some of us are for creating two separate databases, since there are two separate datasources. One, automatic, will change very little over time and requires almost no maintenance. Other datasource will be manual input. Tables and procedures related to this part will change over time.
Some of us are for creating single database, since it will serve one web site. More important this group is concerned about performance issues since almost every select will require join between tables that would be stored in two separate databases. Do these issues exist?
Can you share some insights, comments, links about this?
how can take codes below and put them into one store procedure to supplie a gridview. also i will like to define the row name on the left like i did to the column on the top using the 'AS' Code1.... SELECT SUM(CASE WHEN Month = 'January' THEN 1 ELSE 0 END) AS January, SUM(CASE WHEN Month = 'February' THEN 1 ELSE 0 END) AS February, SUM(CASE WHEN Month = 'March' THEN 1 ELSE 0 END) AS March, SUM(CASE WHEN Month = 'April' THEN 1 ELSE 0 END) AS April, SUM(CASE WHEN Month = 'May' THEN 1 ELSE 0 END) AS May, SUM(CASE WHEN Month = 'June' THEN 1 ELSE 0 END) AS June, SUM(CASE WHEN Month = 'July' THEN 1 ELSE 0 END) AS July, SUM(CASE WHEN Month = 'August' THEN 1 ELSE 0 END) AS August, SUM(CASE WHEN Month = 'September' THEN 1 ELSE 0 END) AS September, SUM(CASE WHEN Month = 'October' THEN 1 ELSE 0 END) AS October, SUM(CASE WHEN Month = 'November' THEN 1 ELSE 0 END) AS November, SUM(CASE WHEN Month = 'December' THEN 1 ELSE 0 END) AS December, SUM(CASE WHEN site_descr = 'SITE1' THEN 1 ELSE 0 END) AS AllTotal FROM dbo.V_results WHERE (site_descr = 'SITE1')
Code2.....
SELECT SUM(CASE WHEN Month = 'January' THEN 1 ELSE 0 END) AS January, SUM(CASE WHEN Month = 'February' THEN 1 ELSE 0 END) AS February, SUM(CASE WHEN Month = 'March' THEN 1 ELSE 0 END) AS March, SUM(CASE WHEN Month = 'April' THEN 1 ELSE 0 END) AS April, SUM(CASE WHEN Month = 'May' THEN 1 ELSE 0 END) AS May, SUM(CASE WHEN Month = 'June' THEN 1 ELSE 0 END) AS June, SUM(CASE WHEN Month = 'July' THEN 1 ELSE 0 END) AS July, SUM(CASE WHEN Month = 'August' THEN 1 ELSE 0 END) AS August, SUM(CASE WHEN Month = 'September' THEN 1 ELSE 0 END) AS September, SUM(CASE WHEN Month = 'October' THEN 1 ELSE 0 END) AS October, SUM(CASE WHEN Month = 'November' THEN 1 ELSE 0 END) AS November, SUM(CASE WHEN Month = 'December' THEN 1 ELSE 0 END) AS December, SUM(CASE WHEN site_descr = 'SITE2' THEN 1 ELSE 0 END) AS AllTotal FROM dbo.V_results WHERE (site_descr = 'SITE2')
Hi guys and gals, I am trying to create a select statement that will return an INT that I will later have to use in another select statement. I have the following code, however, I keep getting an error that says: 'Error116: Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.' My Code is below: //Start of sql CREATE PROCEDURE ADMIN_GetSingleUsers( @userID int) AS DECLARE @userSQL intSET @userSQL = (SELECT User_ID, TITLE.TITLE AS TITLE, Cast(Users.Active as varchar(50)) as Active, Cast(Users.Approved as varchar(50)) as Approved, Users.Unit_ID As usersUnitID, * From TITLE, Users WHERE User_ID = @userID AND TITLE.TITLE_ID = Users.Title_ID ) Select Unit_ID, Parent_ID, Unit_Name from UNITS WHERE Unit_ID = @userSQL //End of sql Can you point to what I am doing wrong? Thanks in advance!
I was wondering if it's possible to have a stored procedure that has two select statements which you can combine as a single result set. For instance:select name, age, titlefrom tableaselect name, age, titlefrom tablebCould you combine these queries into a single result set?
I know I should know the answer to this, but I just can't quite get the syntax down
Code: Select case when zipCode = '10185' Then 'Deliver' Else when zipCode = '2309' And paid = 'Yes' Then 'Deliver' Else When zipCode = '1291' And paid = 'Yes' Then 'Deliver' Else When zipCode = '88221' And paid = 'No' Then 'Hold' Else when zipCode = '34123' Then 'Deliver' End From postalDeliveryDatabase
Hi, OK, trying to return the results from two SQL statements into a DataSet using SqlDataAdapter. The SELECT statements query the same table but are looking for different records based on the date that the records were inserted - the 1st query looks for records fro the current month and the 2nd one looks at the same records but for the previous month. The goal is to be able to do some math within a repeater and get the difference between the two records. Sounds easy enough and it has worked for me in different variations of the same idea but not this time - here's the code: Protected Sub buildPartsReport(ByVal varHC) objConn.Open() sSQL = "SELECT ap.id,item_model,item_sn,aircraft_id,item_loc=item_type+ ' on ' +(SELECT tnum FROM T_Aircraft WHERE id=aircraft_id),apt.tot_time As endTimes,apt.tot_cycles as endCycles FROM T_Aircraft_Parts ap, T_Aircraft_Parts_Totals apt WHERE ap.id=apt.part_id AND report_date= '" & rD & "' AND item_type LIKE 'engine%';SELECT ap.id,apt.part_id,apt.tot_time as startTimes,apt.tot_cycles as startCycles FROM T_Aircraft_Parts ap, T_Aircraft_Parts_Totals apt WHERE ap.id=apt.part_id AND report_date= '" & oldRD & "' AND item_type LIKE 'engine%'" Dim objCommand As New SqlDataAdapter(sSQL, objConn) DS = New DataSet() objCommand.Fill(DS) Repeater1.DataSource = DS Repeater1.DataBind() DS.Dispose() objCommand.Dispose() objConn.Close() End Sub Sorry if it wrapped a bit. The "rD" and "oldRD" are the variables for the date ranges (currently set to static numbers for testing). I'm getting the following error when I run this on an ASP.Net page: System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'startTimes'. The code works fine when run via the Query Tool on the SQL server (SQL 2005 Std) though it produces two distinct "tables" which I'm guessing is the problem. I've tried variations on the code including creating a 2nd dataset and then attempting a merge (no joy) and I've tried the ".TableName" route but it complains about trying to add the tablename twice. Thoughts? I need to get this to work - it is part of a reporting component for an application that I'm developing and I'm stuck. Thanks as always...
first of all is it possible? if so, what am i doing wrong with this
INSERT into TB2
(
ClientCode, EngagementCode, EngagementDescription
)
SELECT (SELECT dbo.tarCustomer.CustID FROM dbo.tPA00175 INNER JOIN dbo.tarCustomer ON dbo.tPA00175.CustKey = dbo.tarCustomer.CustKey INNER JOIN dbo.tPA00007 ON dbo.tPA00175.intJobKey = dbo.tPA00007.intJobKey),
NULL,
SELECT (SELECT dbo.tPA00175.chrJobNumber FROM dbo.tPA00175 INNER JOIN dbo.tarCustomer ON dbo.tPA00175.CustKey = dbo.tarCustomer.CustKey INNER JOIN dbo.tPA00007 ON dbo.tPA00175.intJobKey = dbo.tPA00007.intJobKey)
the first select statement for works fine, but the second one and all after i get a syntax error near 'select'.
this is just a shortened version of the statement. how would i run select statements for a table to be inserted into with different column names. also with items that are hard coded like the 'null'. thanks
I have created a stored procedure with multiple select statements using MSSQL 2000. When I connect to this using a SQLDataSource it only seems to get the first SELECT. I need to access the multiple tables returned by the stoped procedure. Can anyone point me in the dirrection of how to do this.ThanksClearz
I have used several sql queris to generate a report. This queries pull out data from different tables. But sometimes at the same table too. Basically those are SELECT statements. I have created stored proc for each SELECT statement. now I'm wondering can I include all SELECT statements in one stored proc and run the report. If possible, can anyone show me the format?
Hey Guys. I’m having a little trouble and was wondering if you could help me out. I’m trying to create a custom paging control, so I create a stored procedure that returns the appropriate records as well as the total amount of records. And that works fine. What I’m having problems with is reading the data from the second select statement within the code. Anyone have any idea on how to do this? Also.. how can I check how many tables were returned? Here's my code. I'm trying to keep it very generic so I can send it any sql statement:public DataTable connect(string sql) { DataTable dt = new DataTable();
SqlConnection SqlCon = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["MyDB"].ToString()); SqlDataAdapter SqlCmd = new SqlDataAdapter(sql, SqlCon); System.Data.DataSet ds = new System.Data.DataSet(); SqlCmd.Fill(ds);
dt = ds.Tables[0];
//Here's where I don't know how to access the second select statement
return dt; } Here's my stored procedure: ALTER PROCEDURE dbo.MyStoredProcedure ( @Page int, @AmountPerPage int, @TotalRecords int output )
AS
WITH MyTable AS (
Select *, ROW_NUMBER() OVER(ORDER BY ID Desc) as RowNum From Table where Deleted <> 1 )
select * from MyTable WHERE RowNum > (((@Page-1)*@AmountPerPage)) and RowNum < ((@Page*@AmountPerPage)+1);
Select @TotalRecords = COUNT(*) from Table where Deleted <> 1 RETURN
My goal is to run a bunch of select statements from different tables in one database and have them all insert to the same columns/table in the new database. Do I need a new data source for each statement, or is there a way to run all the statements in one set seeing as they all have the same destination. I keep receiving the SQL statement improperly ended error when trying.
I ran the below 2 select statements and ended up seeing multiple cached instances of the same stored procedure. The majority have only one cached instance but more than a handful have multiple cached instances. When there are multiple cached instances of the same sproc, which one will sql server reuse when the sproc is called?
SELECT o.name, o.object_id, ps.last_execution_time , ps.last_elapsed_time * 0.000001 as last_elapsed_timeINSeconds, ps.min_elapsed_time * 0.000001 as min_elapsed_timeINSeconds, ps.max_elapsed_time * 0.000001 as max_elapsed_timeINSeconds
How do I write an sql statement to link tables in two databases and query them? For example: SELECT db1.table1.field1, db2.table1.field1 FROM Table1 INNER JOIN db1.table1.field1 ON db2.table1.field1 = db1.table1.field1
Pricing is a little confusing at my work. My works database from the point of sale has multiple places for price to be. Right now the tables in question are in a SQL database. I am trying to create a user defined function so I can get a list of prices for specific items and for the customer logged into the web page. The tables look like this:Inventory: ItemID, ItemCompany, Description, ListPrice, PublicPriceContractID: ContractNum, ItemID, ItemCompany, MinQty, ContractPriceCustomer: CustomerNumber, CustomerDepartment, Contract1 – Contract4ContractNum ‘99’ is a global contract to all customers. I was able to get the price for this generic contract price, but not for contracts customer may have. Here is what I have so far (with an example item already being pulled up). I am at a loss on how to get the customers contract price with the same function. SELECT Inventory.ItemNumber, Inventory.Company, Inventory.Description, Contracts.Quantity AS MinContractQty, COALESCE (Contracts.ContractPrice, Inventory.WhlCatalogPrice) AS Price, Inventory.WhlCatalogPrice AS ListPriceFROM Inventory LEFT OUTER JOIN Contracts ON Inventory.ItemNumber = Contracts.ItemNumber AND Inventory.Company = Contracts.Company AND '99' = Contracts.ContractNumberWHERE (Inventory.ItemNumber = N'444') AND (Inventory.Company = N'035')
I am developing basket and need a simple way to get price x quantity + total price.
I get back a recordset which has a varying number of items, each item has a price and quantity. Using SELECT ((productprice)*(productquantity)) AS subtotal, product name, productid
I don't know how to add all subtotals to get a total, I have tried putting in SUM but but cant get it to work.
Criteria Retrieve records with independent price and its total volume per minute
SELECT SUBSTRING(st,1,4) AS Ttime,d_price AS Price,SUM(l_cum) AS Volume FROM cmd4 WHERE sd='20060717' AND serial='0455' GROUP BY SUBSTRING(st,1,4),d_price,l_cum
I have an access database and an SQL database and using data transformation services, i want to update the access database using the SQL data.
Can anyone tell me the syntax for referencing the access database?
Is it something like: [TABLENAME].dbo.FIELDNAME ?
Just to clarify, i have
Microsoft Access Database Table 1 (UnitHistory)
SQL Database Table 1 (UnitHistory)
How do i reference these seperately? I want to update the microsoft access database based on the SQL database data.
Eventually i'm trying to update an access database using the data held on my SQL server. Is DTS the best way for me to acomplish this or should i use another method?
Dear Readers,Is it possible, like in Access, to link to tables in other SQL databases that are on the same server? I have a query that I originally had in Access that queered from multiply databases. It did this by having those other tables in the other databases linked to the database that had the query.
For large databases is it a good idea to create indexes for fields that are used in Where statements? Does that improve performance and reduce overhead?
I'm trying to create an email report which gives a result of multiple results from multiple databases in a table format bt I'm trying to find out if there is a simple format I can use.Here is what I've done so far but I'm having troble getting into html and also with the database column:
I'm trying to create a database that takes specific information from a number of databases on different servers to make some reporting that we have much easier.
I'm pretty new to SQL so I'm not sure of the best way to proceed. I read an article that suggested I use the OPENROWSET command. The problem is, the version of SQL that came with one of the programmes we use is limited and will not allow you to turn on the allow "Ad Hoc distributed Queries" so the SLQ statement will not execute.
I'm confused why it won't let me to connect through ODBC as I've created a web page that selects data from this database with no problems!
Here is the SQL statement that I've written to make sure it is the correct one (on the msdn library page it said that this was the ODBC connection):
SELECT a.* FROM OPENROWSET('MSDASQL','DRIVER=(SQL Server);SERVER=APPOLOACT7;UID=sa;PWD=***************', 'SELECT * FROM MDCTestAndDev.dbo.TBL_CONTACT') AS a
I've also created the ODBC connection using the tool on Administration Tools>Data Sources ODBC
Any help would be greatly appreciated (also any ways of selecting from one database and inserting it into another will be helpfull)
I have 7 source databases and one target database, all using the same structure. The structure is made of 10 tables, with foreign key constraints.
I need to merge the source databases into the target (which won't have any data before that process, but will already have the correct schema), and to keep the relationships between the records.
I know how to iterate over the source databases (with SMO foreach), but I'd like to know if someone can advise the best copy method for that context in SSIS ? (I don't want to keep the primary keys, but I need to keep the relationships...)

I am trying to restore multiple .bak backup SQL database files onto a new server. However, I have found that it will not allow me to restore multiple databases at once. Is there a way to do this so that I do not have to manually upload one at a time? I tried adding all the .bak files at once to the backup device window but it only did the first one listed. It would be so much easier to restore them all at once so that I do not have to continue this manual process. I am restoring them via device.

I am writing a fairly complex data automation procedure that basically uses about 5 stored procedures and some additional sql from C# to populate a database. i would like to utilize transactions in C# and sql to help me if something goes wrong. My question is, do i have to maintain the same connection in order to have one transaction for all my Commands. right now i do things like connection.Open();Command.ExecuteNonQuery(); connection.Close(); connection.Open();Command2.ExecuteNonQuery(); connection.Close(); i think i have to keep the same connection open for the duration of all my commands in order to utilize transactions, is this correct? thanks, mcm
Is there a way to execute multiple SQL statements within SQL Server? I'm triyng to write a sql statement that will delete from three tables. I need at least two sql statements to delete from these three tables. Can this be done?
This query brings back 2 rows for each record, one for each case statement. How can I change this to bring in the contsupp.notes for both types of data? Or could it be fixed in the joins?
