Hi,
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.
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 ?
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...
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.

Lars
What is the maximum character limit for table check constraint . For example
ADD CONSTRAINT [xyz]
CHECK (<how many characters are allowed??>)
Do MS SQL Express support Asian character set?
If I want to input Traditional Chinese character, what collation I should use?
Is there any limitation on the no of connect to MS SQL Express?
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!
View 10 Replies View RelatedI'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?
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
View 1 Replies View RelatedI have a table that contains file paths as
ServernamefolderAfilenameA
ServernameFolderBFilenameB
and I need a query to return
ServernamefolderA
ServernameFolderB
I tried
SELECT DISTINCT left(Source, charindex('', Source)- 0) AS String
FROM Table
But that removes everything after the first and I need it to return all data before the last
I have the following scenario, The contents of main file are like :
ServerCentral|||||forum|||||||||||||||is||||||the||best
so||||||be|||||on||||||||||||||||||||||||||||||||||||||||||||it
And I need the output in the following form:
ServerCentral=forum=is=the=best
so=be=on=it
The logic being that multiple and consecutive occurrences of the special character, here - pipe , should be replaced by a single special character.
I have data in a column that starts with 1-4 characters followed by a dash then followed by an number of characters (ex: EU-Surgery).
How do I select everything to the right of the dash when the number of characters to the left of the dash varies?
I'd like to return the left-most character from an 8 character string & the third from the left character too.
Like this ABC00123 returns AC
$query = "SELECT LEFT(uninum,3), RIGHT(uninum,5), clmarea, Date FROM tblunimov";
$result = mysql_query($query) or die(mysql_error());
echo "<div class='tblstyle1'>";
echo "<table class='tblstyle1'>";
echo "<tr><th>ini</th><th>item</th><th>area</th><th>date</th></tr>";
while($row = mysql_fetch_array($result)){
[Code] ....
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());
Hi there guys!
I was wondering if anyone know the number of rows you can import from an external source into MS SQL Server 2000 Developer Edition?
I have tried importing a whole table from another database with over a million records. But failed after 1.7 million row.
Any ideas?
Thank you!
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??

View 2 Replies View RelatedHi 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
I have the fields in my table:
ID, Title, Description, Price, ImageData, Active
I only want it to be possible to have two records at any time with Active=Yes. Active is a Bit, Yes/No, field.
Any help is appreciated.

hi,i have a union statement that works like a charm:SELECT
[Name],
[EventID] AS [ItemID],
[TourID],
[Date],
NULL AS [StartDate],
[Date] AS [SortDate],
[Type] FROM [Events]
WHERE
[TourID] IS NULL
AND
AccessLevel <= @AuthenticationLevel
UNION
SELECT
[Name],
[TourID] AS [ItemID],
[TourID],
NULL AS [Date],
[StartDate],
[StartDate] AS [SortDate],
'2' AS [Type]
FROM
[Tours]
WHERE
AccessLevel <= @AuthenticationLevel
ORDER BY
[SortDate] this statement selects all the records i want from both tables, and orders the entire new table by sort date.what i want to do is to add a limitation on the number of records. i have tried using both LIMIT and TOP commands, but i can't get it working. both of the below statements give me a syntax error saying "Incorrect syntax near the keyword 'ORDER'"first try:SELECT * FROM (<same_statement_as_above>) ORDER BY [SortDate] LIMIT 2second try:SELECT TOP 2 * FROM (<same_statement_as_above>) ORDER BY [SortDate]what am i doing wrong, and how do i achieve what i want?i am working with mssql server 2005 (express locally, and standard on my hosting service). thanks for your help!
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?
Thanks
hello everybody
I created user "MyUser " with rights
1. public for database "Orders"
2. select, update,delete, insert to table Orders.dbo.PersonalInfo
I have table Orders.dbo.PersonalInfoChangeLog
( it keeps information on any update on Orders.dbo.PersonalInfo including
HOST_NAME())
So I don't want anybody to see even structure of this table(Orders.dbo.PersonalInfo ).
if person loged as "Myuser" he can use
1. sp_help PersonalInfoChangeLog
2.Enterpise Manager to see properties of the table
How can limit rights to see structure without generating Application role ?
Thanks
SQL takes all CPU resource on some of the intensive
queries. Is any way to make sure there is something left for other tasks
to be processed? Let's say limit SQL to use no more than 80% of CPU.
Thanks
I was wondering if anyone out there can help me as to how to limit the query results to show only the authors who have written more than one book?
SELECT a.au_lname, au_fname, COUNT(t.title_id)
FROM pubs..authors a
INNER JOIN pubs..titleauthor t ON (a.au_id=t.au_id)
GROUP BY a.au_lname, au_fname
Regards,
someone suggested I use:
select top 20 * from t
where pkc not in (select top 10 pkc from t order by pkc) order by pkc
to simulate the limit function in mysql.
i want to replace the 10 in the inner select with a variable. When I do this:
select top 20 * from t
where pkc not in (select top @counter pkc from t order by pkc) order by pkc
it gives me in an error in sproc. Pls help!!
There is at present (as we accidently found) limitation of MSSQL to return per row maximally 8060 bytes. Message like this comes: "Cannot create a row of size 8279 which is greater than the allowable maximum of 8060".
My questions are :
- Is there any way how to pass it? If I split into more tables (as I have it now) and ask for result where these tables are connected over any ID the result is the same. If I use stored procedures it seems to be ok. Any other idea?
- Will be this ok in SQL server 2005?
hi everybody,
Beside top statement what is the best statement used to limit the display the data?
Thanks...
I have an application that uses a small SQL Server database.
What I need is to prevent the access of an amount of users to the database.
At the beginning I want to limit the access only for 2 users but I want to be able in the future to grant the access to more.
MySQL has a convenient syntax for paging data that looks like this:
SELECT * FROM MyTable LIMIT 10, 20
That would select 10 records, starting from record 20, so that it returns records 20 - 30. This is convenient way to page data, without returning anymore rows than than you need.
However, MS SQL doesn't appear to support that syntax. What is the equivalent sql code to select any N rows from an arbitrary starting point, without having to create a stored procedure?
Thanks in advance :)
Quick question, is there a record limit in MSSQL assuming that we don't use a identity key. I am going to be using a table to sava mail server logs. It will create about 5000 records a minute. Also are there any perfomrance issues once you reach a certain numberof records, assuiming i am indexing one of the columns.
View 4 Replies View RelatedI have a extremely large table and out of that I just need 2 records but based on some logic . For example
IF EMPLOYEE_ADDRESS <> NULL
set Employee_HAS_HOME to 1
ELSE
set Employee_HAS_HOME to 0
Here I can not use just first 1000 records as I am not sure If I will cover the second condition in first 1000 rows . Then I came up with solution like : -
select * from employee_table where employee_address <> NULL LIMIT 1
UNION
select * from employee_table where employee_address = NULL LIMIT 1
And this will give me 2 records which I can use for my testing . But unfortunately this is not working.
Hi,
I am working on building SSIS Packages which will need to extract records from OLTP Servers, and i am half way through building the package, i wanted to test if it is able to extract the records from a particular table on OLTP....basicall i want to test if the package built so far running good?....but the extraction part takes ages as there are millions of records in the OLTP ...i want to limit those records to say some thousands so that i can test it and work on cleaning part in the staging and later after all the chunks are working perfectly i want to set it completely to run for extracting all the millions of records.
Any suggestion would be appreciated.
thanks

Nothing much that i can do..!!
