SQL Server :: Adding A Bunch Of New Records To The English Table / Repeating The Data Entry Into The Spanish Table

Oct 29, 2010

I have two tables for storing language translations - tblEN and tblES. They have the same structure which is nvcEnglish and nvcLocal - both nVarChar fields.

In nvcLocal of the Spanish table, I enter the Spanish translations of words and phrases used within my app. Problem is, when I add a bunch of new records to the English table I also have to go in and repeat the data entry into the Spanish table. I am wondering if there is a way to import the newly added records into the Spanish table using Transact SQL?The plain language query would be something like:

If the data in tblEN.nvcEnglish does not exist in tblES.nvcEnglish then insert a new row into tblES with the values from tblEN

How To Check A SQL Database Table To See If A Record Exists?

May 10, 2010

I have a SQL database that creates a record for every document uploaded by the user to the server. I want to check this table before a user uploads a document to ensure they don't upload a file with name that already exists.

I know how to make the connection and make the SqlCommand to query the table for an existing record. But I don't know how to check the record count from the sqlCommand I made.

Does that make sense?

Using myConnectionCheck As New SqlConnection(myConnectionStringCheck)
Dim myCommandCheck As New SqlCommand()
myCommandCheck.Connection = myConnectionCheck
myCommandCheck.CommandText = "SELECT * FROM Req_Docs WHERE Doc_Name =" & DocName
End Using

SQL Server :: Relationship Which Allows NULL Entry / Error 'FK_Table_Contracts_Table2_PONo' On Table 'Table_Contracts'?

Nov 29, 2010

I have two tables as below.

I tried to establish a relation between two tables in such a way that Table_Contracts will still accept NULL values for [PO_No], but [PO_No] on TableContract will be automatically updated when [PO_No] on Table2_PONo changed. Moreover, if you want to delete a record on Table2_PONo, it needs to be stopped if there is a related data in Table_Contracts.

I set a relation with these parameters:

Check existing data on creation or re-enabling>

Enforce for replication>

Enforce foreign key constraint>

Delete Rule>
No Action

Update Rule>

I got this error

Introducing FOREIGN KEY constraint 'FK_Table_Contracts_Table2_PONo' on table 'Table_Contracts' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.

(primary key)
(accepts null values)

Web Forms :: How To Import Exsisting SQL Server Table To Access Table(new Table)

Dec 10, 2010

my main intention is that, the exsisting table of sql server database(.dbo) with 1000's of records, that should be import to a new access database table(.mdb).for example if we want to had a new table in db2, of exsisting table in db1 with some conditions by using "select * into New_Tabel from (select * from Exsisting_Table where <Condition>) as objectName". Here the new table is created and records inserted in one execution in db2. The same work should be done for access(sqlserver db --> Access db).Here the new access database table with given name (as string_sysdate) must be created dynamically by clicking a button (multiples time creating new table).Is there any query or c# code for sql server database to access database.

Create Multiple RadioButtonLists From A Single Table In SQL Server Using C#?

Nov 11, 2010

I would like to use ASP.net, C# and SQL to display a list of games with radio buttons like below (the x is the radio). One team can be selected for each game.

game 1: x team 4 x team 2
game 2: x team 6 x team 1
game 3: x team 5 x team 3

The game list is stored in a table in an SQL database. So far, I can pull all teams into one big RadioButtonList. I cannot figure out how to create multiple RadioButtonList controls from this single table of games. Does anyone know how this can be accomplished - or reference to an example / tutorial that accomplishes something like this?

C# - DirectoryInfo And Path.GetDirectoryName - Exists Method Returns False While Exists?

Dec 13, 2010

I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.

The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.

while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.

for test I tried to create the folder then it says can't find the path...

userFolderName = @"W:/Webs/ASPPages/cropper/uploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried "W:\Webs\ASPPages\cropper\uploads"
DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........
