How To Save Arrays In SQL Database?
Feb 19, 2008
Hi,
I'm using Visual Studio and Visual Basic to save data about members in a database.
I use SQL-database as it's included.
However, I'm new to this saving in the datbase and wonder how I can at the best save data about a member without having to index each value in the arrays:
The array has 2 index and is declared
dim Results(6, 50) as string
Of course, I can do results11, results12,... results150, results21, ...results250....
But it seems rather awkward to do it this way. I'm sure that there is a better way.
Thanks, any assistance is appriciated!
Best wishes, Per

Hello:I didn't find any documentation that notes save point names are casesensitive, but I guess they are...Stored Proc to reproduce:/* START CODE SNIPPET */If Exists (Select * From sysobjects Where Type = 'P' and Name ='TestSaveTran')Drop Procedure dbo.TestSaveTranGoCreate Procedure dbo.TestSaveTranAsBeginDeclare@tranCount int--Transaction HandlingSelect @tranCount = @@TRANCOUNTIf (@tranCount=0)Begin Tran localtranElseSave Tran localtranBegin Try--Simulate Error While ProcessingRAISERROR('Something bad happened', 16, 1)/*If this proc started transaction then commit it,otherwise return and let caller handle transaction*/IF (@tranCount=0)Commit Tran localtranEnd TryBegin Catch--Rollback to save pointRollback Tran LOCALTRAN --<< NOTE case change--Log Error--Reraise ErrorEnd CatchEndGo--Execute Stored ProcExec dbo.TestSaveTran/*Should receive the following message:Cannot roll back LOCALTRAN. No transaction or savepoint of that namewas found.*//* END CODE SNIPPET */What is really strange, if there is a transaction open, then no erroris thrown. So if you execute as so:/* START CODE SNIPPET */Begin Tran--Execute Stored ProcExec dbo.TestSaveTran/* END CODE SNIPPET */There is no "Cannot roll back LOCALTRAN...." message.Questions:1-)Can someone confirm save point names are case sensitve and this isnot happening because of a server setting?2-)Is this a logic error that I am not seeing in the example codeabove?We have changed our code to store the save point name in a variable,which will hopefully mitigate this "problem".Thx.

The XML generated by notifications object needs to be saved. Where do I save it - in the database. That will still be stored in a table - with drawbacks!

Hi all,
Can someone please brief me on how to save 'pdf' files(there are about 15 files) into a SQL database and retrieve/open it from a datagrid?
I have about 15 pdf files on my webserver and need to save it in the SQL database, so every pdf file saved in the database will have a primary key and the file will be saved either as 'ntext' or 'binary' type...I just have this rough idea.
If someone has a ready code in VB.net then nothing better( i know thats a shortcut :) but it will help me like a tutorial. C# code will do too, I can then convert the code to Vb.net
Thanks a ton.

1-I want to save records from a table located in my database1 on Server1 to a non existing table in another database2 in another server2. (The destination table doesn t exist, I want it to be created with T-SQL). How can I do that using T-SQL
2- Also, is there an other better practice to back up my table before I do some dammage inintentially and destroy the table or the records forever or does SQL server do that automatically for us.
Thanks a lot for your advice.

Hello,
A database EntryForm has a MenuStrip. How could the Menustrip implemented that it would have a Save and Restore data to the database for backup purposes?
What is the Menustrip for? None of the standard Items seems to work. What can be printed or previewed?
This question is NOT about how to save the data into the database from the EntryForm.
Thanks for any answer,

Hi !
I am creating a website with a form that users can fill up the
information. This form is about the school's information of the users.
After fill up this form, the users will have to click the submit button
that will submit the form to be saved in a database.
I have created the database for that form. My question is how can I
save the result of this form to my database. Let's say I have 5
textboxes in that form, name, school's name, school's address, major,
and comments.
thanks a lot in advanced!

Hi,
For some reason I can't use the edit, update or insert features on my remote shared server, so I am looking to create a web page that has text boxes on it, that I can enter data into, that will be saved into my database.
This is opposed to entering the data directly into the database itself. I want to be able to use a webpage, for simply adding new data, and saving it so that the new data updates and saves over the top of the old data.
What are the steps involved in doing this?
Any example code for just one text box would be appreciated, I could then extend it to suit my needs. Tia.

Hello,
I am working on a ASP.NET 2.0 project with an SQL 2005 database.
I created a documents table with various columns including:
DocumentId and DocumentUrl
My documents will always be PDF's of SWF's (Flash Paper Files)
I will need to display this files in my web pages.
My question is:
Should I save the DocumentUrl in the database or should I save the file itself in the database?
And how can I save files in an SQL 2005 database?
Thanks,
Miguel

Hi,
i have a richtextbox control in my application, and want to know how to save and retrieve formatted text in a MS SQL DB.
I found this example in the forum, but I don't know how to use it. Can you please help me solve the problem? Where should I write the code below?
I've just tried it and able to do this successfully.
I basically did this:
load the RTF into the RTB control
created a SQL command, simple basic insert statement:
SqlCommand theSQLCommand = new SqlCommand("INSERT INTO [TableName] (Field) VALUES (@p1)");
SqlParameter theSQLParameter = new SqlParameter("@p1", SqlDbType.Text);
theSQLParameter.Value = this.theRichTextBox.RTF;
theSQLCommand.Parameters.Add(theSQLParameter);
theSQLCommand.Connection = new SqlConnection(ConnectionString);
theSQLCommand.Connection.Open();
theSQLCommand.ExecuteNonQuery();
theSQLCommand.Connection.Close();
then to retrieve it, I did this, again, specifically for this example
this.theRichTextBox.Text = String.Empty;
SqlCommand theSQLCommand = new SqlCommand("SELECT [Field] FROM [TableName] WHERE [ID] = 1");
theSQLCommand.Connection = new SqlConnection(ConnectionString);
theSQLCommand.Connection.Open();
SqlDataReader theReader = theSQLCommand.ExecuteReader(CommandBehavior.CloseConnection);
while (theReader.Read())
{
this.theRichTextBox.RTF = theReader.GetValue(0).ToString();
}
theSQLCommand.Connection.Close();
And was able to do this fine and got all the formatting etc... correctly.

When you create database diagrams in Enterprise Manager, the detailsfor constructing those diagrams is saved into the dtproperties table.This table includes an image field which contains most of the relevantinfomation, in a binary format.SQL Enterprise manager offers no way to script out those diagrams, soI have created two Transact SQL components, one User Function and oneUser Procedure, which together provide a means to script out thecontents of the dtproperties table, including all of the binary basedimage data, into a self documenting, easy to read script. This scriptcan be stowed away safely, perhaps within your versioning software,and it can subsequently be recalled and executed to reconstruct allthe original diagrams.The script is intelligent enough not to overwrite existing diagrams,although it does allow the user to purge any existing diagrams, ifthey so choose.Once these two objects have been added to any database, you may thenbackup (script out) the current database diagrams by executing thestored procedure, like this:Exec usp_ScriptDatabaseDiagramsBy default, all database diagrams will be scripted, however, if youwant to script the diagrams individually, you can execute the sameprocedure, passing in the name of a specific diagram. For example:Exec usp_ScriptDatabaseDiagrams 'Users Alerts'The Transact SQL code for the two objects is too long to paste here,but if you are interested, I will email it to you. Just drop me a noteat: Join Bytes! (Remove bothinstances of TAKE_THIS_OUT from my email address first!!)-Clay

helo..
I want to save file it size about 200MB to the database and after that
I want to get it from the database, the colmun type that i want to
save the file to it is NVARCHAR(Max).
I am using MS sql server 2005.
I was using this code to do this with Image Or Ntext column type but
it dose not working with NVARCHAR(Max) column?
Function SaveFileToDB(ByVal FileName As String, ByVal TblName As String, ByVal FldName As String, ByVal ColumnIDName As String, ByVal RowID As String) As Boolean
