SQL Server :: Query To Select Data From Multiple Tables And A Different Database?
Dec 1, 2010
Is there a way to select data from multiple tables other than the UNION ALL statement. Addtionally I need to select data from a different database.
My current statement is as follows (there are alot more fields but I have shortened it ):
SELECT server.dbo.SRFILE.SR_GROUP, server.dbo.SRFILE.SROWNERSHIP, server.dbo.SRFILE.SRCONMAE, BSFLBWF_1.Incidentx,
BSFLBWF_1.Severityx FROM server.dbo.SRFILE INNER JOIN
BSFLBWF AS BSFLBWF_1 ON BSFLBWF_1.Incidentx = server.dbo.SRFILE.SRONUMBER
WHERE (BSFLBWF_1.Closex IS NULL).........
SELECT u.Email FROM UserProfiles p, aspnet_Membership u WHERE p.RulesCheckBox = 'True' AND u.UserId = p.UserId This gives me a list of registered member email addresses that have selected the RulesCheckBox in their profile, so I can email them with an email script. There is a relationship between the Membership table and the UserProfile table, so it finds the email addresses from the Membership table where that user has the RulesCheckBox checked in their profile (in UserProfiles table). I'm wanting to add some additional names to this list, from a different table. The purpose is so I can manually add email addresses to the additional table, so the additional email addresses will also receive the same email, even though they aren't registered members of the site. So how can I adjust that SELECT statement so this one is combined with it somehow?:
SELECT Email FROM ExtraEmails WHERE Rules = 'true'
One of my peer wrote a query based on multiple tables using joins. One of the table is in a different database The query was taking much time
1. Create an SP 2. Create a temp table and copy all records from the external db 3. Avoid using Left Join as much as possible and use Inner Join 4. Create and use indexes 5. Remove tables/columns that are not necessary
In this scenario, I would like to suggest to use Covering Index, but how can it be created for multiple tables and a temp table?
I am a little new to this concept so bear with me.1) I need to query atleast 35 tables using linq to sql(SQL server database) . I am not able to add all the database entities in Linq to sql classes?
2)(View Model issue) When I use List<Reportcollection> and also List<Receipt> to convert the result then its giving an error that "Cannot convert list<anonymous> to list<string>"
A follow up question concerning the DAL layer part .. The first question about dealing with large objectsI have one table (PlacesTable) that is connected by like 6 other tables (1:Many and Many:Many relations)
In my DAL should I put a big query that join the 6 tables + the m:m reference tables (btw it produces multiple data that I don't need Please refer to my old question) and place all the data in it's specific object property or, should I use a single query for each table and create an object for each fetched table .. and finally send those to the UI ?If I wasn't clear enough please let me know what I further information do you need to know!
i create view in sql server and execute a select query using AND operator on it using vb.net and bind data with gridview...but i am not getting result in grid
I'm implementing a BLL layer and have a few questions. First, in my DAL, there is a contacts table, the select method is a sql query against a sql server 2000 database. The preview data returns everyting as expected. The query is
[Code]....
The BLL method is built like so
[Code]....
When using the BLL method to a gridview, the results of the subquery are not displayed. There are also other methods, each having a different where clause for ContactRole_ID and each is having the same issue of not displaying the subquery reult in the gridview. No error, but no data is displayed for the subquery either. Here is the templatefield of the gridview
[Code]....
Another item that is causing an error is in trying to update a record. Here is the DAL update method
[Code]....
And the BLL update method
[Code]....
The error says i have extra parameters, but have no clue where the extra parameters are being picked up. The error isObjectDataSource 'odsContacts' could not find a non-generic method 'UpdateContact' that has parameters: _ContactID, _Active, _ContactName, _Office, _VirtualOffice, _Pager, _Fax, _Home, _Cellular, _Email, _ContactRole_ID, Active, ContactRole_ID, ContactName, Office, Email, VirtualOffice, Pager, FAX, Home, Cellular.And the objectdatasource
Here I'm using three tables given below. As u can see in the below three tables, 3 columns(P_Id,PdtName,PdtImgUrl) are same. Now can any body tell me how can I retreive values of 3 columns(P_Id,PdtName,PdtImgUrl) without repeatition.
have a database and I've created a DBML Linq-to-SQL file to represent this database. I've created a new aspx page and dropped a linqdatasource and a formview control onto it. When I configure the linqdatasource it gives me the choice only to select * from one table...but I want to pull from multiple tables. e.g. I have tables like simple_person, simple_address, simple_phone, and I want to pull from all of them.
i would like to find out how to go about displaying data from multiple database tables on the same page. What i mean is it would look like the feeds on the facebook home page where you can see the information like newply uploaded photo or a new post.
I have two tables, and i want to display any newly created row on my home page from either table in the same control. Currently, i have two gridviews, but i want the data from both tables be displayed together.
how can I display a linq query in a gridview that has data from multiple tables AND allow the user to edit some of the fields or delete the data from a single table?
I'd like to do this with either a linqdatasource or a linq query. I'm aware I can set the e.Result to the query on the selecting event. I've also been able to build a custom databound control for displaying the linq relations (parent.child).
However, I'm not sure how I can make this work with delete? I'm thinking I may need to handle the delete event with custom code.
I have a view that has to render information from 3-4 tables. I therefore chose to create a viewModel for this. I am using EF as DAL.The information to be displayed is SiteId, SiteName, SiteDetails from one table.Associated to Site, other table Event_type has information about Events in the system with fileds like EventId, EventName, Event ScopeId.EventScope is another table with ScopeID and ScopeDesc Also, there is Site_Event_Implemnetation table that stores all the events associated to a site. It has SiteId, EventId, EventUnitIdEventUnit is another table that stores all the unit types.Now my Details ViewModel has to display the info SiteName, SiteDetails. And associated to that a grid of events with info on EventName, Scope Desc, Unit Desc1. How do I formulate my query to retrieve this info in my repository layer using Linq to EF?
I have excel file with columns EmpName,Date1,Date2,...Date7 .I want to insert EmpName into Employee table after inserting i will get EmpNo(Identity column) with that i need to insert Date1,Date2...Date7 into TimeSheet table.
My Excel structure is like this EmpName 8/1/2010 8/2/2010 8/3/2010 8/4/2010 8/5/2010 8/6/2010 8/7/2010 Naresh 17:00-2:00 17:00-2:00 14:00-12:00 7:00-12:00 7:00-12:00 .. Off Similarly 500 employees data
I want to insert name i.e into Emp table after inserting i will get EMpNo i.e identity column with that i should insert Date1(8/1/2010) i.e excel header to date7 into Timesheet table Date column and corresponding time into TimeIn and TimeOut.I will split the time.I just want write Stored procedure for this task.
My database tables are like this
Emp-EmpNo,EmpName,CompaignId Timesheet-TimeID,EMpNo,Date,TimeIn,TimeOut,TotalHours Date in Timesheet should be like this TimeId EmpNo Date TimeIn TimeOut T otalHours
1 100 8/1/2010 17:00 2:00 9hrs
2 100 8/2/2010 17:00 2:00 9 hrs
7
I just want this logic on how to insert Date1 to date 7 as 7 rows into Timesheet table and EMpName into EMployee table.while accesing each row i need to insert Date 1 to date7 as 7 rows into Timesheet table.
I basically have a series of tables from one database that have an identical structure thus making retrieval of all records fairly easy (I just use a UNION ALL statement). However I need a list of values from another table within a different database that contains information regarding the group of the data.
I so far have the following:
SELECT Table1.* FROM Table1 UNION ALL SELECT Table2.* FROM Table2 UNION ALL SELECT Table3.* FROM Table3 UNION SELECT Database.dbo.SRFILE.SR_GROUP FROM Database.dbo.SRFILE INNER JOIN Database.dbo.SRFILE.SRONUMBER = Table1.Incidentx
I keep receiving a unable to parse message however all I need to retreive is the SR_GROUP value but just don't know the correct syntax. Is it actually possible to do this as the structure of SRFILE is not the same as Table1/2/3.
i am developing a web site in Asp.Net using Visual Studio 2008.i want to know that how can i search a keyword that will be entered by the user, i want the key word should be searched in complete database(all the tables)using a single query.I am using sql database. how can the keyword be searched using like parameter...
This code works just fine for me to select * from x,y,z. However what I want to do is retrieve the values return and assign them to variables. How do I go about this?
I have one Store Procedure that generating report ..
For storing the data there , i used many temp. tables. There is many Select Query , little less insert and delete query.
Now if there is huge data around 1 lac in temp table my select query taking to much time and also may be insert and delete query
I added Primary key to all auto Increment Field in temp table. Also defined Clustered index on that primary key as unique Clustered index to improve the performance .
But there is not so much improvement in case of huge temp table.
Right now the whole Store Procedure is taking time to complete around 1.5 days or around 30 hours ..
So i want to increase the performance as much that it completes on nearly 3-4 hours.
I have created a search page which outputs results in a repeater. It uses a stored procedure to search a table %like a textbox value, what's the best way to make it search multiple tables and output the results on one button click?
As i could just use seperate stored procedures and repeaters for each table i want to search, which is only 2, but this seems inefficient.
