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 that
I need to store strings longer than 255 characters. To do this I
change the data type in SQL Server, then I change the parameter code in
the calling procedure, as per below:
However, when I do this, for some reason, the field is still limited to
255 characters - when I try to update the field with 256 characters,
the error 'Application uses a value of the wrong type for the current
operation.' occurs.
Why is this? I've checked that the correct data is contained in the
parameter. When I look at the data in the database, the column in
question shows the content, whereas the next column, which has always
been of type text, shows '<LongText>' - does this mean anything? Do I
need to do something special to convert the column from nvarchar to
text?
Hai Every one i am facing a werid problem it is related to storing a long text data in SQL 2000 the text data is some thing like the following "dshjfsjlksdjakdjlksadjfeidkadflkdsajfieawirfjalkdfjsakdfjaiekdvnmckaumnmmmmmmmmmmmmmmmoadifdjsakdjfauiereoweiiiiiiiiiiiiiiiiiiiiiiiiiiidalfkjdsa,mlfdsdflvmsaldifsdjfskladfakdfjakladkalfkfadkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkadlkfjaidfajfkamcmmmmmmmmmmmmmmmmmmmmmmmmmmmmmiadlmfalierfmaerjeaiaelelllllllllllllllllllll..." in short it is really long so i opted to go with TEXT data type as it states that it can store more than 8 kb but when i try to insert this data it gives me error stating that Text data type cannot be of length more than 128...........? What am i doing wrong........if Text is not the proper datatype to store such a data then can anyone suggest some thing better............... Thanks in advance Austin
I want to insert a value which has the UTF-8 encoding into a field of the database which has the "text" data Type but it saves like this : " ?????????????? "
I would be thankful if u tell me how should I save it ? here is the SqlComand I wrote :
I'm using a function which splits a comma delimitted list of numbers which I call from a stored procedure. The list is defined as a NVarChar which has a maximum length of 4000 characters. I often need to pass more than 4000 characters. If I do so, I receive the error message below. Is there any way around this limitation? Thanks.

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:
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.
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.
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.
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!
Hi, I have an ASP.NET application that uses VARCHAR extensively in the tables and, more importantly, stored procedures (a couple hundred of them).
This app needs to start accepting foreign language in some areas, so I was wondering if there was some way to go through the tables and, more importantly, the stored procedures and change all "VARCHAR" references to "NVARCHAR" ?
Are the stored procedures stored as a text file somewhere on the server? If so I could use some sort of "replace" software utility to go through and change all VARCHAR to NVARCHAR
Hello I use SSIS to load a Unicode file into a single table I Use a "slowly changing dimension" task to load the destination table and when i map a column (DT_WSTR) to a column with the datatype nvarchar(max) i have an error message that say that i can't map theses columns because there have not the same datatype.
I find a workaround : i map all my cols except the colums that must fill the cols with datatype nvarchar(max) , and after i modify manually the 2 subtask generated by the "slowly changing dimension" task (the insert and the update) and with this way i don't have error messages It works fine but is it the good way?
In a column I have some values for part names. The 6th character tellsyou where the part came from, and this is the same scheme for everysingle part in the database.If I want to do something like return the basic name of a given part,without the factory identifier character, I need to replace thatcharacter with a '_' character. (So for instance '11256CA' and'11265AA' and '11256MA' would all just get turned into '11256_A' andonly one row would be returned in the SELECT DISTINCT statement)I know how to replace an instance of a given character using replace(),but how can I alter a specific character in a string if all I know isthe index of the character within the string?TIA,-CS
Hi everybody,I'm using SQL Server Management Studio Express.I'm trying to create a field which contains a text entered by the user. So, it should be able to contain at least 500 characters.I used the type "nvarchar(MAX)". The problem is that the type contains about 50 characters max!!I couldn't find out where and how to fix that. If you have any idea :)Thanks a lot

I am so frustrated, I have upsized a data base from access to sql 6.5 and now had to clip data to fit into a 255 field? I have been looking for weeks to find a solution for this.
I am writing a discussion board very much like this one and need the message text to hold more than 255 chars. I have tried to create a table with a blob and text, The text will not allow me to specify the size when creating from a script (ASP) using create table. If I dont specify a size, it creates it as 16?
Been working on this for several weeks and cannot locate anyone that can answer this question, I want to create a column that will hold more than 255 chars.
IS there something in Sql 6.5 that I need to set to allow more than 255 on a text field? What am I doing wrong?
Please respond. Thank you. Mike (you can see this board here www.454ss.com)
nvarchar(max) I have a nvarchar(MAX) “Description” field in my SQL Server 2005 database. Somewhere I think I read that nvarchar(MAX) is the size of 4000. My question is in my Insert Stored Proc set ANSI_NULLS ONset QUOTED_IDENTIFIER ONGOALTER PROCEDURE [dbo].[syl_CodeScheduleTypeInsert] @ScheduleName nvarchar(50), @ScheduleDescription nvarchar(????????)ASBEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; BEGIN TRY INSERT I What number should replace the ???????? with? nvarchar(4000) is that correct? I tried nvarchar(MAX) and nvarchar but both versions only input one character into my database table. Please help a newbie out, cheers!

I uploading an image from a web page into Sql Server 2000 database. I call a stored procedure with the parameter @Flag of type Image. When I tried to pass a null value to this parameter I got the error:"Operand type clash: nvarchar is incompatible with image".I was adding the parameter like this:sqlCmd.Parameters.AddWithValue("@Flag", DBNull.Value);After trying few different things I found a workaround using the following:sqlCmd.Parameters.Add("@Flag", SqlDbType.Image);sqlCmd.Parameters["@Flag"].Value = DBNull.Value;Possibly a bug in the SqlCommand.Parameters.AddWithValue method ?

Hi I have an insert stored procedure with a parameter @eventDate date type date time. I have written a web form that takes the textbox.text value and assigns to the @eventDate parameter using a querystring. Howevr when I run the application I get a SQL Exception error converting data type nvarchar to datetime. I have tried dssqlInsertEvent.InsertParameters.add("EventDate", convert.todatetime(txtEventDate.text)); wbut received another error. Any assistance would be greatly appreciated.
Hey folks, the question is fairly simple, unfortunately the answer has proven rather elusive.
Is it possible to declare a variable which would then be used to identify either a column or table in an SQL statement?
Here's a basic idea of what I'd like to do:
DECLARE @myVar AS NVARCHAR(50)
SELECT * FROM @myVar
or
DECLARE @myVar AS NVARCHAR(50)
SELECT @myVar FROM MyTable
I'm probably looking for some sort of built in function that will accept an argument here... like COLUMN(@myVar) or something of the like. I just don't know where to look...
I am using MS SQL Server 2008R2 along with VB 2010.The first question is: why is it even trying to convert anything to numeric? I have NO numeric data types. And I don't have any nvarchar data types either. I'm very confused.Doesn't nchar include any and all characters, in any combination? Should I change everything to text data type? Maybe something else? Some values are going to be blank. The Lab/Source Lots have numbers, letters and dashes.
This is a common error for SQL Server, but I got it in a uncommon way.I have a table called - tblIDNumber where there are two columns - IDN_Number [NVarchar(200)] and Temp [BigInt]
If I run, SELECT Â * FROM Â Â dbo.tblIDNumber WHERE Â IDN_IDNumberTypeStaticValue = 33 Â Â Â Â AND IDN_Removed = 0 Â Â Â Â AND CAST(IDN_Number AS BIGINT) = 1
SQL Server give me the error: Msg 8114, Level 16, State 5, Line 1 Error converting data type nvarchar to bigint.
I first thought IDN_Number in type 33 has characters, but it doesn't, becasue the below query works!!!
UPDATE dbo.tblIDNumber SET Temp = CAST(IDN_Number AS BIGINT) WHERE Â IDN_IDNumberTypeStaticValue = 33 Â Â Â Â AND IDN_Removed = 0
To workaround, I ran the query,
UPDATE dbo.tblIDNumber SET IDN_Number = '123' WHERE Â IDN_IDNumberTypeStaticValue = 33 Â Â Â Â AND IDN_Removed = 0
and then I ran the first query, and SQL Server does NOT give me the same error -Â Msg 8114, Level 16, State 5, Line 1 Error converting data type nvarchar to bigint.
Second query approved there is nothing wrong from converting the value in IDN_Number to a BigInt, but the third query gave the hint that data might be the cause?????
finally, I found the root cause to be an index that the first query uses :
CREATE NONCLUSTERED INDEX [IX_tblIDNumber_Covering] ON [dbo].[tblIDNumber] ( [IDN_Removed] ASC, [IDNumberCode] ASC ) INCLUDE ( [IDN_Number], [IDN_Reference]) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 85) ON [PRIMARY] GO
If I remove the index, the first query works without the error.
I'm pretty desperat after trying solving the above problem in several days. I hope somone here can help me :-)
I have this stored procedure. When I try to Execute the storedprocedure where I have a date as parameter I get the above error.
I checked (many times), that the input parameter is a datetime format (30-05-2008) and also I checked the tabel and it is datetime format. I checked the table to see if it was english datetime format - but all the datetimes that are listet are listed in danish datetime format DD-MM-YYYY.
In the stored procedure I try this:
fProjectSkuTimeStamp >= @ReducedTime
I can't figure out where it gets that nvarchar from?
