C# - Split A String And Update Muliple SQL Tables?
Jul 27, 2009I have an Article object with the following properties:
Article Name (varchar)
Article Body (varchar)
Article Tags (varchar)
The Article Tags is a space delimited string of text values that a user has tagged the aritlce with. The 3 properties are passed to a stored procedure.
I now want to do the following:
1) Insert the Article Name and Article Body in the dbo.Articles table and return the article id
2) Insert each value of the Article Tags string in the dbo.Tags table as a separate row but first check for duplicates. If duplicate then return the tagid of existing record, if new record then return the new tagid
3) insert the article id and each tagid as a separate row in the dbo.TagMap table
I need to know the best approach to how I would accomplish this, also being conscious that it does not cost too much in performance.
Timeout Using SQLite - Create A Database And Several Tables - To Populate The Tables With Data From Arrays
Jul 25, 2012I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand

View 3 RepliesSql - Find Tables Used From A .net Application To Remove Unused Tables?
May 10, 2012We are presently developing an application, let's call it APP1, which uses a SQL Database which have about 800 stored procedures, 600 tables, etc. APP1 was originally created in order to replace another application, APP0, from which we do not have source code but only SQL tables, Stored Procedures, views, etc. Previous programers of APP1 used some DB objects from this same database and added some other objects specific to APP1 because it becomes bigger than APP0. And we do not need APP0 anymore as APP1 does all what we want, and more.
So, now, we are thinking about a way to find out which objects are used by APP1 in order to remove objects which are ONLY used by APP0.What is the best approach to discover all objects used by APP1 without having to open every single class and form?
Once we will have a complete list of these objects, it will be easy to use a program we bought which detects all dependencies for all SQL Objects specified directly from SQL and remove objects which do not return from any dependencies. Any ideas of how I could get this list without having to go through all our program that have many, many, many classes and forms?
Note : I know, in a perfect world, all calls to PSs and tables should be in a DAL but in the case of the application we're presently working on ... this is not our case! Yippy! (sarcastic yippy) ;)
Note 2 : This application is not using any ORM. So all queries are directly using SqlCommand. So any call to any DB objects are in string format.

View 3 RepliesCan't Get It Right Multi-tables
Jun 10, 2012I really need assistance for this multiple problem am facing here. Let me take you to my hell: I've got three tables in my database that are:
1) tbAthlete (athleteID, nationID, gameID, fname, lname)
2)tbNation (nationID, nation)
3)tbGame (gameID,game)
I connected the database to vb and created a (form1) based on a query that use all fields except IDs. that form1 is just good as displaying and navigating throug records. Now i wanted to link that form1 to another form(2) which will allow me to update and add new record. in the form2, country and game need to be combobox as there is no need to enter new record for them. so when adding new record, only "tbAthlete" table get affected. form1 works as excpected. how do i go for the form2

Comparing Two Tables?
Aug 30, 2009I want to track changes of a document which sits in a DB table like :
document starts
document continues 1
document continues 2
document continues ...
document ends
(Each line is a record but if needed I can combine them all to one record)I have the document before changes in one table and the document after the change in another table.My problem is that if I just compare them by ID then I'll get many more changes than actually occured. Ex: If a line (/record) was added between record 2 and record 3, instead of tracking 1 change I will see that all the records from 3 and on have changed (because they will be pushed off by one record). Can be also something which knows to compare documents and I'll take the information out to document for comparison.
Connection Between Two Tables?
Dec 31, 2010I have a table called PARTS and table called PARTEXT.
PART has:
PartID
PartDescription
PartCostPrice
PartSalePrice
PARTEXT has:PartID
PartImagePath
For some reason (please don't ask me why) the designer of the database splitted the tables.I need a sql command to "combine" between the two tables by making new View, so it will show the content of the PART table and in each row it will get the PartImagePath of the same PartID that both tables have.

In the following part of my code a DataTable will be generated based on the sum of the records on both tables.Based on the bellow code ACTIVITYLOOKUP datatable is having "MAIN FACILITY USED","Description","TypeName","Type","Id" columns. The issue happens when there is a row with the same MAIN FACILITY USED entity. The datatable will not show it (filter it?). Do you know where the problem lies? and how it will be fixed without any modification in database?

Sql - Get Information From The 2 Tables Into 1 Row?
Feb 8, 2012Dim LocationList =
From rows In db.Locations, clientRow In db.Clients, stateData In db.Ref_States
Where rows.State = stateData.ID
Select ClientName = clientRow.Name, rows.ID, rows.Address1, rows.Address2, rows.City, StateName = stateData.Name, ShortStateName = stateData.ShortName, rows.ZipCode Order By Address1
That's what I have and it is very wrong. Everything shows up, but the data displays incorrectly, displays more rows than exist.
Dim LocationList =
From rows In db.Locations, clientRow In db.Clients, stateData In db.Ref_States
Where rows.State = stateData.ID And rows.ClientID = ucClientID And rows.ClientID = clientRow.ID
Select ClientName = clientRow.Name, rows.ID, rows.Address1, rows.Address2, rows.City, StateName = stateData.Name, ShortStateName = stateData.ShortName, rows.ZipCode Order By Address1
