Which way to go?
Have two separate programs(Visual Studio-Coded in Visual Basic) that share the same sql 2005 database(called Night Audit)
The tables are called RoomSettlement and Settlement.
They were separate tables and separate programs in the past because it was just exported in excel to a visual integrator that dumped the amounts into our accounting software.
Now needing to combine the two tables(that have no link) on to a single excel sheet daily where the tables have the same date:
Table: Room Settlement – Field: RoomSettlementDatetxt =
Table: Settlement – Field: SettlementDatetxt
Any Ideas on the best way to go? (Link the tables with a foreign key and primary key, maybe union based on date, or any easier suggestion with out having to change a lot of the program )
a table called checkboxitems populates the checkboxlist (checkname, checkid) and when submitted the selected items are put into another table's column selecteditems like "1,5,9"
is there a way to do an inner join or something to get the checkname dependent on which which items are in the selectitems

I am running SQL Server CE on Visual Studio 2005. I have created 2 tables and wish to establish a relationship between the two tables. However, I could not find a proper way to establish the connection. Anyone can provide some help on this? thank you.
I'm building a Search Function with different pull down options. I have 9 Tables and 6 of them are not related. How do I build an effecient SELECT? Thanks I'm somewhat new to MSSQL.
Hi, I am trying to create a create for two table A and table B which have no relationship each time. For TableA, there are 3 columns like ID, APoints1, APoint2. For Table B, there are also 3 columns as ID, Qty, BPoints. There is no internal relationship for these two tables. But there may be same ID inside A and B for some records. Now I want to create a datagrid for displaying the information as :
Please Notice that I can't use directly SQL script as following from table A and table B because there is no relationship for Table A and Table B, otherwise the recult set would be wrong:
Select A.ID, Sum(A.APoints1 + A.APoints2) - Sum(B.Qty * B.BPoints) WHERE A.ID = B.ID group by A.ID
Inner join will remove rows from the first table if there is not a corresponding row in the 2nd table. Outer join will keep the rows, and use all NULL values to fill in the gaps in the 2nd table.
In general outer joins are more likely to grow a result set and inner joins are more likely to shrink one (though that will depend on the data and the query). For this reason, it is usually better when building complex queries to try to do your inner joins before your outer joins, because then you will keep your result set smaller for longer and thus the later joins can run faster.
I am relatively new to MS SQL (not a novice, but hardly a master).
I am working on a content management application for a magazine publisher. It’s written in ASP (VB Script) and being created on Dreamweaver 8 with an MS SQL 2000 database. Now, I’m trying to decide the best and fastest approach to coding a complex INSERT and UPDATE function. My question isn’t as much about the SQL (although that will probably come up after I decide how to do this), but about the procedural steps and approach I shuold be taking to do this.
Reporters will use an online form to enter their story into the system. It collects the usual data: Headline, byline, story content, and the story category (feature, opinion, entertainment, business, sports, etc.). Each story may belong to MULTIPLE categories (feature & business, for example).
So, I’ve created three tables to support this many-to-many realtionship:
Story Category StoryCat (a junction table with the IDs from both the other tables).
The online form has a dropdown menu which pulls the available categories from the Categories table. When the reporter has entered the data I use ASP to performs the insert just as you would expect it to.
The next step needs to be to update the StoryCat table so that it creates a new record with the StoryID of the record it just inserted, along with the CategoryID that was in that record.
------------------
As I said, I’m not sure of the best way to do this.
Should I just pull back the last record inserted and then create a procedure that would insert into the StoryCat table (which is what I’m thinking of doing on the confirmation page), or is there another approach I should take (perhaps some sort of temporary table or stored procedure?).
It's been always said that it is best to put index on commonly joined fields in the table. But putting too much index on the table would cause the table to be slow on insert and update.
My question is, how do you deal with your fields that uses look up tables? Like for example for these fields
Those fields don't come a big part in the table, though when I query the table I always join them with their respective primary table to get their respective text value. Do I still need to put Index & FK relationships to these fields?
What fields are normally good candidates for index or fk relationships?
I just ran across an issue on a SQL 2000 sp4 db where RI was being maintained solely with triggers. I am attempting to change the primary key of a parent table and cascade the results to all its children without using the vendor-supplied trigger code (long story...) using an INSTEAD OF trigger.
My question is: does SQL Server create any kind of relationship between the inserted and deleted tables that I could exploit since the key field is unavailable?
I am trying to avoid having to add a surrogate key to each of the children just for this activity (as there are many M rows in each and no other suitable unique column combinations that span all the child tables).
I have two tables, Inspections and InspectionDetails. The InspectionDetails only contains information if an inspection found violations. Some inspections don't look for violations so inspectiondetails would have no entry.How can I create a 0-Many relationship between these two tables?Inspection Table has : InspectionID, InspectionDate, TypeofInspection, Inspector..InspectionDetail Table has : DetailID (an auto-incrementing identity column), InspectionID, SectionViolated, ViolationDescription, InspectorNotes.
I need to create a relationship between a local table and tables on alinked server. I used the design table wizard and selected therelationship property wizard. In the reslationship property wizard,the tables that I need to get the keys from in the linked server do notshow up. Is there a way to do this, or I simply don't have enoughpermission to tables in the linked server. On the local server, theSecurity tab of linked server property has Local Loging "sa", RemoteUser "sa" and Remote Password "****". Thanks for your help.
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?
I am developing a database in PowerPivot and I am wondering how to create many relationships between the same 2 tables. All relationships must be active.
Let me give you a DUMMY example: let's say that the database has 2 tables, the Employee table and Manager table:
Supose I have two records in a parent-child relationsuip (actually I have many more such records). Does SSIS offer any support ask for inserting one record into the parent table, the other into the child table, and updating the foreign key of the child to point to the parent?
TIA,
Barkingdog
P.S. I have to do just this as part of the datawarehouse test I'm running. Seems like a common task but I don't recall anything in SSIS addressing the issue.
I used a function to create dataset as below: Public Function GetSQLDataSet(ByVal SQL As String) As DataSet ...... MyConnection = New SqlConnection(MyConnectionString) MyCommand = New SqlCommand(SQL, MyConnection) MyDataSet = New DataSet MySQLDataAdapter = New SqlDataAdapter(MyCommand) MySQLDataAdapter.Fill(MyDataSet) ...... End function It works fine. How to code a function to return a dataset in which there are two tables and relationship?
Currently i am defining a simple relationship between Customers->Orders->Order Details through the Database Diagrams feature in the SQL 2K. Using the Server Explorer, i can see the Database Diagrams, but when i try to "drop" the Database Diagrams into the page, it gives the error message.
I would like to know the procedures to retrieve the database relationships from Database Diagrams and manipulate them through ADO.NET
I prefer to "convert" already defined relationship using SQL Server Database Diagrams into XSD file or probably there is another method to "read" those relationship and manipulate them.
I have two table studenTtable and courseTable which is each student take more than one course . 1:M...for example Student1 take 2 courses (C1 , C2). Student2 take 3 courses (C1,C2, C3).I need to create a table/View that contain student information from StudentTable plus all the courses and the score for each course from CoursTable in one row.
for example Row1= Student1_Id ,C1_code ,C1_name ,C1_Score ,C2_code,C2_name ,C2_Score Row2= Student2_Id,C1_code, C1_name,C1_Score,C2_code ,C2_name ,C2_Score , C3_code,C3_name,C3_Score
and since Student one just have two courses , I should enter NULL in 'Course 3 fields'.My Struggle is in the insert statement I tried the following but it show an error
Insert Into Newtable ( St_ID, C1_code,c1_name, C1_Score ,C2_code ,C2_name,C2_score,C3_code ,C3_name,C3_score) Select (Select St_ID from StudentTable) , (Select C_code,c_name,c_Score from Coursetable,SudentTable where course.Stid =Studet.stid) , (Select C_code,c_name,c_Score from course ,student where course.Stid =Studet.stid ), (Select C_code,c_name,c_Score from course ,student where course.Stid =Studet.stid );
I'm fully aware that the New table/View will break the rules of normalization ,but I need it for specifc purpose.I tried also the PIVOT BY functionality but no luck with it .I also tried writing a code using Matlab (because it is high level sw that it is easy to learn for people not expret in programming as me) but didn't know how to combine the Student and Courses Matrices in my loop.
I am trying to insert data into two tables with a SSIS package. One table has a foreign key relationship to the other table's primary key. When I try to run the package, the package will just seems to hang up in bids. I have found two ways around the issue but I don't like either approach. Is there a way to set which table gets insert first?
If I uncheck the check constraints option on the child table, the package will run very quickly but this option alters the child table and basically disables the constraint. I don't like this option because it is altering the database.
The second approach is to set the commit level on both tables to say 10,000 and make sure that the multicast component has the first output path moved to the parent table. I don't like this option because I am not sure if the records are backed out if the package should abend after records have been committed.

I have spent several hours hurting my brain tring to solve the following. I am hoping one of you SQL gurus can help me out.
I have two tables (each with two fields):
Group with GroupName and GroupDescription
Here is some sample data:
HR HumanResources IT Information Technology Boston BostonOffice NJ NewJerseyOffice
GroupMember with GroupName and UserID
Here is some sample data:
IT CMessineo NJ CMessineo Boston JSmith IT JSmith
What I want is a single stored procedure that when passed a UserID will return a result set that lists all the groups and a 1 or ) if the UserID is a member of that group.
For example calling the procedure and passing CMessineo would produce this result:
HR 0 IT 1 Boston 0 NJ 1
Can this be done in a stored procedure?
This is what I have so far, but I am in over my head:
( @UserID varChar(40) ) As SELECT"GROUP".GROUPNAME, (SELECT ??? FROM"Group", GroupMember Where"Group".GroupName = GroupMember.GroupName and GroupMember.UserID = @UserID)
Hey all. Sorry to ask such a basic question, but I am needing to combine data from about 3 different databases into 1 ad hoc report. I know that you can include multiple datasets, but I need this to act as 1 dataset so that the table data between all databases are related to one another.
I know very little about the potential of analysis services / integration services, so I don't know if they contain the answer to my problem.
Does anyone have a suggestion of how I should approach this problem (as always, speed is a bit of a consideration here as well).
However, the userelationship function does not override the active relationship between Operation & Advice and so the measure is limited to Advices directly filtered by the Operation table.
If I delete the relationship between Operation and Advice, then the measure works as expected i.e. Operation indirectly filters Operation Commodity which filters Advice.
Masters, The below queries return the data that I seek, but I have no idea how to combine them into a single query.
SELECT SUM(TOTALSVCAMT) - SUM(TOTALPAYMENTAMT) - SUM(TOTALADJAMT) as [0 to 30] FROM MDM2 WHERE DATEDIFF(day, SERVICEDATE, getdate()) between '0' and '30'
SELECT SUM(TOTALSVCAMT) - SUM(TOTALPAYMENTAMT) - SUM(TOTALADJAMT) as [31 to 60] FROM MDM2 WHERE DATEDIFF(day, SERVICEDATE, getdate()) between '31' and '60'
SELECT SUM(TOTALSVCAMT) - SUM(TOTALPAYMENTAMT) - SUM(TOTALADJAMT) as [61 to 90] FROM MDM2 WHERE DATEDIFF(day, SERVICEDATE, getdate()) between '61' and '90'
SELECT SUM(TOTALSVCAMT) - SUM(TOTALPAYMENTAMT) - SUM(TOTALADJAMT) as [90+] FROM MDM2 WHERE DATEDIFF(day, SERVICEDATE, getdate()) > '90'
Any assistance that can be provided will be greatly appreciated. Grasshopper

Hi I am ramesh here from go-events.com I am using sql mail to send out emails to my mailing list
I have difficulty combining a select statement with a where clause stored in a variable inside a cursor
The users select the mail content and frequency of delivery and i deliver the mail
I use lots of queries and a stored procedure to retrieve thier preferences. In the end i use a cursor to send out mails to each of them.
Because my query is dynamic, the where clause of my select statement is stored in a variable. I have the following code that does not work
For example
DECLARE overdue3 CURSOR LOCAL FORWARD_ONLY FOR SELECT DISTINCT Events.E_Name, Events.E_SDate, Events.E_City, Events.E_ID FROM Events, IndustryEvents + @sqlquery2 OPEN overdue3
I get an error message at the '+' sign which says, cannot use empty object or column names, use a single space if necessary
How do I combine the select statement with the where clause?
