As part of a product install (using InstallShield)...
I create a SQL Server Express instance (say "X") via a silent install I supply a script to create a database in instance X.
The idea, of course, is to have a fully automated install. But there's one problem I can't quite see how to work around:
- the CREATE DATABASE statement needs the name of a file to contain the database, and that file needs to be in a folder that belongs to the instance (e.g. Microsoft SQL ServerMSSQL.1, Microsoft SQL ServerMSSQL.2, etc).
Is there a syntactic variant that allows me to avoid this problem?
Data(id int, product_id int, property_id int, value float)
Data.id references Headers.id
Headers.id is a primary key, Data has clustered index (id, product_id, property_id)
Headers has several thousand rows, Data several million. I want to return all rows from Data for a given product_id and a given property_id such that Header.id is in a given range.
Right now I am doing
SELECT id, time, value FROM Headers H, Data D WHERE H.id = D.id AND H.time >= @StartTime AND H.time <= @EndTime AND D.product_id = @ProductID AND d.property_id = @PropertyID
This query can take 10+ seconds to run, though once I run it for a given product_id, queries for different values of property_id are much faster. Try a different product_id, and it takes longer. Given that there are millions of records in Data, is it reasonable for it to take this long? The index was suggested by Query Analyzer's Index Tuning Wizard, and I tried a couple variations on the query without any noticeable performance improvement. But, I'm no DBA...anyone have any tips? I googled a bit but couldn't figure out the right way to phrase my question to find any good info...thanks in advance

I have a table (tbl_a) with 2 columns: itemNames | Date . ItemNames can have duplicates. I have another table (tbl_b) with date ranges in 2 columns: startDate | endDate.
what I would like to do is: query tbl_a where date between startDate and endDate of tbl_b.
I have 2 tables Staff and Class which are as follows
Staff ID (Primary Key) FirstName MiddleName Surname Etc. . .
Class ID (Primary key) LessonTemplateID TeacherID TermID AssistantID
LessonTemplateID and TermID link to other tables which i don't need right now.
The Class.TeacherID and Class.AssistantID both link to the Staff.ID
I am trying to create a query where i can say i want to select a class.ID of lets say 12 and display both the Teachers name and the Assistants Name.
If i do just one join between Staff.ID and lets say Class.TeacherID all is fine and i can display the teacher.FirstName for a particular class.ID. However my problem is when im trying to display both teacher and assistant. Every time i try to create a query to do this the query comes back blank.
Im really stuck on this and just can't figure it out (is it even possible?).
How is the best way to make a function for summing an arbitrary number of times values (table parm?)- I 've read it's necessary to convert to seconds, sum then convert back, but Im' wondering if there's an alternative.
Here's the example I want to sum: 00:02:01:30 00:01:28:10 00:01:01:50 00:06:50:30 00:00:01:50
Hi all, I am currently moving from access queries to SQL and am using the query Builder In Visual web developerto help me with the SQL Code..This has been easy while just querying the one table adapter but Now I am stuck..I have a table adapter that links to an SQL Server database through a connection in web.config.I have another table adapter that links to DB2 through a different Connetion in web.config.My question is ..How do you query from one table adapter to another.Each table adpater can only query based on the 1 connection ? Thx,Ray..
I need to query a database with about 3 million records using a 'like' statement on various varchar columns. I've have a non-clustered index on the columns included in my query, but the performance is still pretty slow. Can anyone suggest ways to increase the speed of my queries? Does full-text indexing improve performance or does it just facilitate more advanced searches (which I don't need)? Would char instead of varchar datatypes be faster?
Hi, I have been using Microsoft Access for a couple of years and we have just switched to SQL Server. However, I'm having problems querying the Mysql databases our company has in place. I have managed to establish connections in the Visual Studio but can't seem to link tables from two different databases like I could in Access. Is this possible? Also, is it possible to connect to the mysql database via management studio? Apologies for my complete lack of knowledge!
Hi everybody, Our SRS reporting security model had to be designed so that the access is by individual report basis and by user. I cannot give access to individual reports based on windows AD group. Because everybody in that group does not need to have access to a particular report. Two people from one AD group needs access to say Report1. Only one person need to have access to Report2 etc.... Creating lot of AD groups for the security is also not advisable.
Right now I can tell right away users having access to a particular report as the number of reports and the users is small. But I want to design a report that can give me a list of users who have access to a specific report. How do I query the reportserver database to get this information. I mean is this information saved in any of the tables? Can you please give any info that you know of such information? Thank you in advance for all your help,
Hello I am writing a stored procedure and instead of "hard coding" the size of the procedure parameters I would like to set them to the size of fields in my database. for example instead of declaring a parameter like this: @ProjectDescription varchar(500)
I would like to do something like this:
@ProjectDescription varchar(Select size of "ProjectDescription" From Projects);
I am working on an application with a number of tables (which I can't change) that have data of the form a1, b1, c1... a2, b2, c2...a3, b3, c3... The tables contain 5 to 10 sets of data in each row.
I want to create a stored procedure to return a cursor with a row for each set of data for a row of the table. I know I can use unions:
select a1 as a, b1 as b , c1 as c... from sometable where pk=@pk
union
select a2, b2, c2... from sometable where pk=@pk
union
select a3...
Is there a way that is more efficient (eliminates requerying the table and all the unions)?
I am implementing an application that is looking into another System’s database (DBF). I need to query out new orders that have been put in daily. What is the best way to handle this situation? Should I write a service or have a trigger setup in MSDE? I just need to do a simple SELECT statement that grabs orders between a date range and update my SQL database (MSDE). I am not looking for specific code examples, just a solution.
I'm in a trouble. So, I need to query some data in DB2 with Reporting Service. I don't know if there's a way to do it, without using DTS Package, because if I did it, I'd be replicating it, and it's not the case. 'Cause I just want to query the data in DB2 and not bring the data to SQL.
There's a provider that I can do it? Suppose I use a Linked Server, and add a Net-Library based on their Operational System, it would resolve? If not, what would be the best way of resolving this trouble??
Hello,I need to come up with a stored procedure that will allow me to readdata from another database. The database I need to read the data fromis a UniData residing on a Unix server. The stored procedure needs toreside on my sql 2005 server. The task is very simple in Access as wehave ODBC connections set up to the UniData via Informix (or IBM)UniData ODBC drivers. I can easily combine my UniData and Sql Servertables from within access. However, I can't seem to find a way toreplicate the same behavior in MS SQL Stored Procedure without the useof Access. Is that even possible?Thanks,Marek
I need help with a query, and I haven't seen anything like this in a SQL book.
I will use the Northwind database for this example. The tables I am using are Products, Order_Detail, and Orders. There is a many to many relationship between Products and Orders, that is resolved by the Order_Detail table. Suppose I want to find out which products are related to each order. How would I query the tables?
Folks,While I still have some hair left, can someone help me with thisquery?I have a table "TestRunInfo". Amongst other fields there are"TestRunIndex" (Pri Key), "TesterID", "Duration", and "Status".The Status field links to a Status table, which links the index valueto a more meaningful label "Pass", "Fail" etc...As you may have guessed, there is a record for each test that anindividual tester runs, and with that record is a duration, and status(1,2,3 etc).What Im trying to do, is create a datasheet view, with a single rowfor each testerID, summarising that Testers work as follows:TesterID, Total Duration, Count of passed tests, Count of failed testsSo far I have:Select TesterID, sum(Duration), count(Status) FROM TestRunInfo GROUPBY TesterIDBut this of course purely gives the total number of tests run by thatengineer as the count. I need to break it down. Help? Someone?Please?!?!?TIASteve
I wonder how the query will be executed when querying to views.Is database engine will be extract the tables that are used to create the view and query for the result ?
I have a Fact Table with a ID column as Primary key and clustered index is created. And also I have 4 dimensions FK's of data type INTEGER. And finally, I have one aggregation measure in the Fact Table.
Now, my situation is How can I improve the speed of querying the fact table by creating any of the below indexes?
to determine if a user is a member of a predetermined role, but how do I ask what the role name of the querying user is instead? Basically I want to do something like:
SELECT * FROM CityTable WHERE City IN (SELECT City FROM CitySecurity WHERE SelectGroup = ROLE_NAME)
I'm doing this because the "CitySecurity" table contains security information from another system that has been imported into SQL Server, where the 'SelectGroup', as part of process, will be named the same as the SQL Server role.
I have a table (we will cal DateTable) with several (20) columns, each being a date type. Another table's (Project) PK is referenced in the DateTable.
I am trying to write a query that will pull all dates for a specific project from the DateTable if they meet certain criteria(i.e. if the date is <= 7 days from now.
I started with a normal select statement selecting each column with a join to the project and then a where clause using
(DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()) OR (DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE())) ...
The rest of the columns(all with OR between them).
The problem with this is that because I am using OR once one of the dates meets the criteria it selects all the dates that are associated with the project. I ONLY want the dates that meet the criteria and don't care about the rest.
Obviously because I have all the columns in the select statement... So I need something like
Select ALL Columns from DateTable d Join Project p where p.ProjectID = d.ProjectID AND only dates BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()))
I created an Image for the Database in sqlserver 2000. When I am querying directly the database as "Select * from employee", it is returning the result set.
But, when I am querying Database image with same query. It is giving error
Server: Msg 208, Level 16, State 1, Line 1 Invalid object name 'Employee'
It is expecting the Database Owner. If I do query like "Select * from [Owner].employee", it is working fine.
My requirement is not use owner in queries, it should be simple query ("Select * from employee").
Can any one, help me out. Thanks in advance. Bhupesh
Is there any way to deploy reports to a Report Manager in SQL Server Reporting Services 2005 if the reports query SQL Server 2000 databases? Or are only 2005 databases able to deploy to the web?
Also, if I have a report that queries both, can I deploy it to the web on the 2005 Report Manager with a linked server to the 2000 server?
I'm trying to run a query on a SQL Server 2005 table which has a WHERE clause that requires a query from my SQL Compact table.
SELECT * from RemoteDB.TESTDB.dbo.Objects
WHERE Last_Updated > '2008-05-21 10:51:00'
AND Object_PARENT IN (select Object_CODE from LocalDB.PDADB.dbo.Objects)
Basicallly on a linked system, this query would find all new objects in my main database where the same objects exist in my local database. This would work just perfectly, no problems.
Now, the local database is actually on a PDA running SQL Server Compact Edition. There is currently no support for creating a linked environment. I have the option of pulling the table off the local db and pushing it to the remote db and then running the above query from within the single db and then retrieving the list of new entries and pulling them down to the local db but that is a HUGE amount of bandwidth, even if I just used the single primary key column.
Would anyone maybe have a little advice for me on how I could possibly achieve the above result on SQL Server Compact please?
I'm fairly new to SQL and am just setting up a Windows 8 app using an Azure SQL server. The issue I have is looking up a part number supersession and getting the latest number. One part number can have multiple supersessions (ie RTC5756 > STC8572 > STC3765 > STC9150 > STC9191 > SFP500160 ).The data I am supplied monthly has both the superseeded items and the supersession information in both columns and is not easy to decipher - for example:
The newest part number is kept in a separate table - called "source" - which in this instance is SFP500160. I need access to the latest part number but also to the part's previous numbers, due to the fact that some people may still be stocking them as an old part number and for them to search by. Is there an easy and efficient way of doing both a lookup for the supersessions and a join on the two tables to minimize the queries on the database?
