Datatype Character Limit

Feb 7, 2007

I am trying to store long text so I gave the field in question the TEXT datatype. But it only lets me store 1023 characters. I was expecting (but not quite needing) 2,147,483,647 characters when using the TEXT datatype. Can some one point out what I am missing.

Great forum, my first post, ahhh....

I will continue to search the forum for my answer. Thank you for taking the time to read this.

...uh, something like that...

Mar 28, 2008

I€™m having a problem with a storedprocedure in SQL Server 2005 Developer Edition: I have declared a varchar(max) variable, but when a try to assign a large string it gets truncated to 255 characters, I get the same result if a declare the variable with varchar(8000), ¿can someone help me fix this?, I don€™t need the full 8000 characters, but I need more that just 255.
Thanks.

Excel 255 Character Limit :(

Aug 8, 2006

I am using VB.NET / SQL to extract data from an Excel spreadsheet and insert it (via a dataset) into an SQL database.

My SQL select to form the dataset is:
Select 0, '01/01/1905', '00:00' , 'Description: ' + [DESCRIPTION] + '<br/><br/>Type: ' + [Field5] + '<br/> Thankyou' As Description From [Primary Schools$]

I am using Jet for the connection, the connection string is:

sExcelConnect = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Path ofile.xls;Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"""

My problem is that, although Description and Field5 themselves are not above 255 characters, the combination of the two, plus my own text do come out as more than 255 characters and as such get truncated.

I have tried using cast and nested selects, but to no avail.

Any body got any ideas ?

The 4000 Character Limit For Expressions

Apr 4, 2006

I am building rather large SQL statements using expressions and I am about to hit the 4000 character limit. First, what were the reasons for setting such a low limit? With it in place you are forced to come up with other solutions, but perhaps that was the intention.

Speaking of limits, what are the limits for storing a value in a string that is defined in a package configuration file? What are the limits when creating a string within a script task and then use it to set a string variable in the package? What are the limits when using a string value as an input parameter to an Execute SQL Task using OLE DB? Do these differ depending on the connection type?

I guess I'm getting a bit paranoid about limits, but I don't want to hit any others late in the design.

Regards,
Lars

Character Limit For Variables Inside A Stocked Procedure

Feb 23, 2007

I am currently having a problem where my SQL server seems to lock any variables to 1000 characters (ie. varchar(8000) can only hold 1000)I have read in numerous sources it was possible to change that limit so the varchar can truly hold the 8000 characters and not stop at 1000, but there was no info on how to do this.I am looking for a "How to" to put this limit to 8000.Thank you!

Need Workaround For 4000-character Limit On CLR Sproc Parameters

May 11, 2007

I've written a managed (C#) stored procedure with the following signature:


[Microsoft.SqlServer.Server.SqlProcedure]
public static void Sproc(string startDate, string endDate, string idList)...



Sometimes when I call this sproc, my comma-separated list of IDs exceeds 4000 characters. How can I get around this problem?

I guess I need something equivalent to NVarchar(MAX), but for CLR sprocs instead of TSQL.

Any thoughts?

When Changing To Type Text From Nvarchar, The 255 Character Limit Is Maintained?

Jul 23, 2005

Hi - I am changing a field from type nvarchar to type text, given thatI need to store strings longer than 255 characters. To do this Ichange the data type in SQL Server, then I change the parameter code inthe calling procedure, as per below:cmd.Parameters.Append(cmd.CreateParameter("@title", adVarWChar,adParamInput, 255, title));becomes:cmd.Parameters.Append(cmd.CreateParameter("@title", adLongVarWChar,adParamInput, 1073741823, title));However, when I do this, for some reason, the field is still limited to255 characters - when I try to update the field with 256 characters,the error 'Application uses a value of the wrong type for the currentoperation.' occurs.Why is this? I've checked that the correct data is contained in theparameter. When I look at the data in the database, the column inquestion shows the content, whereas the next column, which has alwaysbeen of type text, shows '<LongText>' - does this mean anything? Do Ineed to do something special to convert the column from nvarchar totext?Many thanks,Iain

T-SQL (SS2K8) :: Find String Before Character When Character Appears Multiple Times

Numeric Datatype To Ssis Variable Datatype Conversion Problem

Apr 24, 2008



Good afternoon,

I have an issue with an ssis variable datatype.

The scenario is as follows:

I have a stored procedure:


PROCEDURE [dbo].[sp_newTransaction]



@sourceSystem varchar(50),

@txOut NUMERIC(18,0) OUTPUT

AS

insert into scn_transaction (sourceSystemName) values(@sourceSystem);

SELECT @txOut = @@identity


Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).

I execute the stored proc with the following sql with an OLE DB connection manager:

exec sp_newTransaction ?, ?

The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:

User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1

The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.

At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.

I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.

Thanks much,

B

Read Chinese Character From SQL(SQL Server 2005) Database Table Column And Display Chinese Character

Feb 1, 2008

Hi!

I have a table like this below and it doesn't only contain English Names but it also contain Chinese Name.
CREATE TABLE Names
(FirstName NVARCHAR (50),
LastName NVARCHAR (50));
I tried to view the column using SQL Query Analyzer, It didn't display Chinese Character.
I know that SQL Server 2005 is using UCS-2 Encoding and Chinese Character uses Double Byte Character Set (DBCS) Encoding.
I want to read the FirstName and LastName columns and display in Window Form Data Grid and ASP.NET Grid View.
I tried to use this code below and it didn't work. It convert some of the English Name to Chinese Character and it display the chinese character and some still in the original unreadable characters.
Does anybody know how to read those character from SQL Table and display the correct Chinese Character without converting the English Name into Chinese also?
Thanks

int codePage = 950;
StringBuilder message = new StringBuilder();
Encoding targetEncoding = Encoding.GetEncoding(codePage);
byte[] encodedChars= targetEncoding.GetBytes(str);
.
message.AppendLine("Byte representation of '" + str + "' in Code Page '" + codePage + "':");
for (int i = 0; i < encodedChars.Length; i++)
{
message.Append("Byte " + i + ": " + encodedChars);
}

message.AppendLine(" RESULT : " + System.Text.Encoding.Unicode.GetString(encodedChars));
Console.Writeline(message.ToString());

2 GIG Limit

Aug 6, 1998

When creating a database, SQL Server 6.5 seems to have a 2 gig limit. What I mean is that if the device chosen is over 2 gigs SQL Server displays the size of the device as anegative number. This prevents me from being able to expand the database when I need to. Can anyone tell me why this is so, and if there`s anyway around it??

4gb Limit

Mar 26, 2007

Hi There

I recently read up and found an msdn forum post that said the 4gb limit only applied to data files not log files.

However recently i had an error on a sql express database saying that the log file was full, the database log file was set to auto grow and there was plenty of space left.

So i am guessing the 4gb limit applies to any database file mdf or ldf, is this correct ?

Thanx

Connections Limit?

Hi,

I have an application with a DAL that has an interface with SQL Server.
The application has 400 users that open the web forms.
My question is:
Is there a limit of the parallel connections that can be opened? Or the IIS is managing all the access to the DB? Should I worry about the performance Or it's normal behaviour for ASP.NET applications?
