Large String Data
Feb 11, 2004I have a web site that allows user to enter large strings into a database (comments, etc). What is the best way to do that? Right now I have them limited to 25 characters and the data type is varchar. Is there a better way?
Thanks!
Best Way To Do Large String Manipulation - URGENT !!!
Oct 24, 2001Hi,
I am building a string (basically XML) on the fly in stored procedure (SQL 7.0). I am using one local variable @str_xml varchar(8000) to build this string.
Now my problem is I can store maximum upto 8000 characters in "varchar type". And I can't use text field as SQL Server doesn't allow "text type" to be used as local variable.
I am thinking to use 2 or 3 local varchar variables and then return them separately to front end and will do contatination at the front end. But I think it would be ugly way to do as I have to check every time in stored procedure the length of string.
Any suggestions to do this in some other way would be greatly helpful to me.
Thanks

How To Retrieve Large String From Stored Procedure?
May 4, 2007Hello! This is my scenario...
Development - Visual Studio 2005
Database - MS SQL 2005
I have written a stored procedure that has a output parameter whose type is NVARCHAR(MAX). Then I use C# to wrap this stored procedure in OLEDB way. That means the OleDbType for that parameter is VarWChar.
This works fine if the string size is less than 4000. If more than 4000, the remaining part will be chopped off. The situation gets worst if I replace VarWChar with LongVarWChar. There is no error nor warning at compiling time. But there is an exception at run time.
So... Does anyone here can help me out? Thanks in advance.
SQL Server 2005 - Save Tran Save Point Name Case Sensitive?
Feb 11, 2006Hello: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.

How To Save Pdf Files To SQL Database?
Sep 26, 2005Hi 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.

How To Save Arrays In SQL Database?
Feb 19, 2008Hi,
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

How To Save Contents Of Text Box To Database?
May 6, 2006Hi,
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.

Save And Retrieve RTF TEXT FROM SQL DATABASE
Jul 18, 2007Hi,
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.
Transact SQL :: Key And Indexes On Two Column Data Table Or Parsed View (Large String Of Data And Filename)
Oct 4, 2015I am studying indexes and keys. I have a table that has a fixed width of data to be loaded in the first column which is parsed in a view based on data types within the fixed width specifications.
Example column A:
(name phone house cost of house,zipcodecountystatecountry)
-a view will later split this large varchar string basedÂ
column b: is the source filename of the data load (varchar 256)
....
a. would there be a benefit of adding a clustered or nonclustered index (if so which/point in direction on why)
b. is there benefit of making one of these two columns a primary key (millions of records) or for adding a 3rd new column as a pk?
c. view: this parses the data in column a so it ends up looking more like "name phone house cost of house zipcode county state country" each having their own column.
-any pros/cons of adding indexes (if so which) to the view instead of the tables or both for once the data is parsed?
