VARCHAR(MAX) Only Contains 8000 Characters?

Nov 25, 2007



Hi,

I had a VARCHAR(MAX) parameter declared in my stored procedure and trying to concatenat single column from a table which has~500 rows into a string and keep in this variable, if i am not mistaken, i read that the VARCHAR(MAX) actually can hold up to 2GB of data, so it make me confuse why the variable which i declared as MAX size, can only hold up 8000 characters, any idea?

Regards,
Derek

MDX Query Above 8000 Characters

May 23, 2006

Hi,

I have a MDX query which is of an aprox length of 10000 characters. I
have to execute the query from within the stored procedure in sql. To
run this query I use the openrowset method.

If the length of my query is less than 8000 characters my query
executes perfectly, but the moment it exceeds 8000 characters it stop
working. Please suggest a solution for the same.

Sample Code:

declare @mdxqry varchar(8000)
declare @SearchCond varchar(8000)

set @SearchCond = @SearchCond + '
[ProductsAccounts].CurrentMember.properties("AS Date") <= "' + @TDate
+ '" '

set @mdxqry = '''WITH ' +
'MEMBER [Measures].[Difference] as ''''[Measures].[Expected Interest
Amount] - [Measures].[Adjusted Interest]'''' ' +
'MEMBER [Measures].[Loan Closed within Report Period] as ' +
'''''iif(cdate([ProductsAccounts].CurrentMember.properties("Closed
Date")) < cdate("' + @ToDate + '"), "Yes", "No")''''' +
'MEMBER [Measures].[ClosedBeforeLastInstallment] as
''''iif([Measures].[Loan Closed Before Last Instal]=1, "Yes", "No")''''
' +
'SELECT ' +
'{[Measures].[Expected Interest Amount], [Measures].[Adjusted
Interest], [Measures].[Difference], ' +
'[Measures].[Zero Interest Transactions],
[Measures].[ClosedBeforeLastInstallment], ' +
'[Measures].[Loan Closed within Report Period]} ON 0, '

set @mdxqry = @mdxqry +
'{Filter([ProductsAccounts].[Account Id].Members, (' + @SearchCond +
'))} on 2, ' +
@BranchFilter +
'FROM InterestAnalysis'''

set @mdxqry = 'SELECT a.* FROM
OpenRowset(''MSOLAP'',''DATASOURCE="SERVERNAME"; Initial
Catalog="DATABASENAME";'',' + @mdxqry + ') as a'

exec(@mdxqry)

I have already tried splitting my query into smalled chunks and
executing it, but still I face the same problem.

This is how I have Done it:

declare @mdxqry1 varchar(8000)
declare @mdxqry2 varchar(8000)
declare @SearchCond varchar(8000)

set @SearchCond = @SearchCond + '
[ProductsAccounts].CurrentMember.properties("AS Date") <= "' + @TDate
+ '" '

set @mdxqry1 = '''WITH ' +
'MEMBER [Measures].[Difference] as ''''[Measures].[Expected Interest
Amount] - [Measures].[Adjusted Interest]'''' ' +
'MEMBER [Measures].[Loan Closed within Report Period] as ' +
'''''iif(cdate([ProductsAccounts].CurrentMember.properties("Closed
Date")) < cdate("' + @ToDate + '"), "Yes", "No")''''' +
'MEMBER [Measures].[ClosedBeforeLastInstallment] as
''''iif([Measures].[Loan Closed Before Last Instal]=1, "Yes", "No")''''
'

set @mdxqry2 = 'SELECT ' +
'{[Measures].[Expected Interest Amount], [Measures].[Adjusted
Interest], [Measures].[Difference], ' +
'[Measures].[Zero Interest Transactions],
[Measures].[ClosedBeforeLastInstallment], ' +
'[Measures].[Loan Closed within Report Period]} ON 0, '

set @mdxqry2 = @mdxqry2 +
'{Filter([ProductsAccounts].[Account Id].Members, (' + @SearchCond +
'))} on 2, ' +
@BranchFilter +
'FROM InterestAnalysis'''

set @mdxqry2 = 'SELECT a.* FROM
OpenRowset(''MSOLAP'',''DATASOURCE="SERVERNAME"; Initial
Catalog="DATABASENAME";'',' + @mdxqry + ') as a'

exec(@mdxqry1 + @mdxqry2)

Thanks in Advance

Dealing With More Than 8000 Characters

Nov 14, 2005

In SS 2000 it seems that there is no variable data type that can hold more than 8000 characters (varchar) or 4000 unicode characters (nvarchar). I've seen posts where multiple variables are spliced together to extend this limit. I am looking at performing string manipulations in an sproc and I need to be able to deal with the full 2GB/1GB limit of text and ntext field types. Is this possible? How do you deal with that?

Varchar Exceed 8000 Issue

I was trying to build a string based on one field from one table in Stored Procedure. I know if I declare A VARCHAR variable for the string, it won’t allow to exceed 8000. If does, it will truncate the reminding parts of the fields. What might be the simple solution for that? Even though I know I might need to use several substrings but how?

Varchar Output Greater Than 8000 Chars

May 20, 2007

hi all, I'm after a way to produce a single-lined output of a char/varchar string replicated over 8000 times.

basically I've been given a task to create a stored procedure which can accept any integer to replicate a string X times.

From what I've read the replicate() fn will covert to varchar of max 8000 bytes.

I've thought about creating a UDF to accept the varchar and int and run a loop to keep outputting but 'print' will pass an endline to the buffer which is no good for my loop.

Any help would be great on this. Thanks.

Error In SQL-Server 2005 With Varchar 8000

Jun 5, 2006

Hello,

We have migrated a sql server 2000 database to sql server 2005, this was done through scripts (table, stored procedures and data).

To access this database we are using an ASP.Net 2.0 application which uses the sqlhelper Aplication Block to connect to the database.

Everything works fine except one Stored Procedure which has an OUT varchar(8000) parameter.

We use the following .Net Code to execute the stored procedure this stored procedure:

aParams[2] = sSerDatos.GetParameter("@DominiosMenu", DbType.String, 8000);
aParams[2].Direction = ParameterDirection.Output;

sSerDatos.ExecuteNonQuery("VM_SDominiosMenu", aParams)

When we invoque the sqlcommand we get this sqlexception:
The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 3 ("@DominiosMenu"): Data type 0xE7 has an invalid data length or metadata length.
If we change the DbType.String Size to 4000 in the .Net code everything works, this same procedure work correctly in SQL Server 2000 with the same .Net code.
Any help would be appreciated.
Thanks,
Sam

Stored Procedure Varchar (8000) Limitation.

Mar 12, 2008



I have this sql statement in a stored procedure

SELECT @sql=@sql + '''' + convert(varchar(100), pivot) + ''' = ' + stuff(@sumfunc,charindex( '(', @sumfunc )+1, 0, ' CASE ' + @pivot + ' WHEN ' + @delim + convert(varchar(100), pivot) + @delim + ' THEN ' ) + ', ' FROM ##pivot

in the statement, where @sql is defined as DECLARE @sql varchar(Max). the problem is that this statement produces results that are in excess of 8000 characters and the results are truncated. Is there anyway to avoid this? I know that it's not possible to user ntext/text as a local variable, and if i try to return the result as an ouput paramater, only the first result is returned.

my code is based off of this article http://www.sqlteam.com/article/dynamic-cross-tabs-pivot-tables
Thanks for any suggestions.

Input Parameter Greater Than Varchar(8000)

May 30, 2006

Hi

I need to pass the where clause of my statement as an input parameter for a stored procedure. As this is built dynamically within the program (Borland C++), it could sometimes exceed the maximum 8000 bytes of a varchar. I thought of sending in two input paramenters and concatenating them into a memo in the sql, but cannot seem to be able to execute the memo variable (i.e. exec(memo) doesn't work). Is there any other options for passing in such a huge parameter.



Also, I do not think there is any other option than passing in the where clause: passing in seperate parameters and building the clause in sql would require over 300 parameters to be passed, and as the possible number of combination is indefinate, I cannot have a different Stored Procedure for each potential case.



Thank you

How To You Convert An Oracle Long Field To Varchar 8000

Jan 17, 2007



I need to handle this conversion in SSIS and not on oracle.

The following expression is executed on a datatype of dt_str with a length of 8000.

SUBSTRING((DT_STR,8000,1252)Column_name,1,8000)

Records longer then 4000 bytes take an error path

The next expression with 4000 bytes works but there is truncation.

SUBSTRING((DT_STR,4000,1252)Column_name,1,4000)

Basically I need to know how to cast a text or ntext into a varchar or nvarchar using ssis but I need to capture the first 8000 byes without truncation.

is this possible?

Using SSIS Reading From oracle I can convert to a text or ntext field but I am having a hard time going directly to a varchar.

Executing Sql Code From Text Field Or From Multiple Varchar(8000) Rows In A Table

Jul 20, 2005

Does anyone know of a way to execute sql code from a dynamically builttext field?Before beginning, let me state that I know this db architecture isbuilt solely for frustration and I hope to make it better soon.Unfortunately, there is never a non-crucial time in which we can do anupgrade, so we are stuck for now.Point 1:There are multiple tables: students, courses, cross-referencestudent/courses, teachers, cross-reference teacher/courses, andothers.Point 2:Yearly archiving is done by appending a 2 digit year suffix to thetable and rebuilding the table structure for the current year. Thatis, each of the tables named above has an archive table for 1999,2000, 2001, etc. This leads to many tables and a big mess whenunioning them.Point 3:A history report is run by building a big query that unions each unionof tables (students, courses, etc) by year. This query has grown toobig for a varchar(8000) field. Actually, it's too big for 2 of them.Point 4:I don't want to write code to maintain any more varchar(8000) fieldsfor this query. It should be much more easily handled with atemporary table holding each bit of yearly archive data. I have builtthis and it works fine. I have also figured out how to pull the rowsfrom that table, concatenate them, and insert the resulting lump intoa text field in another table.Point 5:I haven't figured out how to grab the 5 or so records from that tableand execute them on their own. I figured I could grab them, put theminto a text field that's big enough to hold the whole query and thenselect and execute that text field. I've had no luck with that and Ihaven't had any luck finding any references that might help me withthis problem. I keep thinking of nesting execute() calls, but thatdoesn't work.I'm open to questions, potential solutions, hints about different wayto approach the problem, anything.Many thanks in advance,Rick Caborn

How To Make Escape Characters In Varchar

Jan 5, 2007

I am trying to use this:

INSERT INTO BizNames ( [Key], [Name] ) VALUES ( 0, 'Bob's Lumber' );

The apostrophe embedded in the name value is giving me headaches. I tried using double-quotes and [] to delineate the value but then I get complaints that a "Name" is not allowed in this context.

How do you turn the embedded characters into an escape character so they can be ignored by SQL Server and passed into the table field.

Varchar Absolute Max Length Of 1024 Characters. Why?

Oct 1, 2000

Hi all,
I have a strange situation. I have a field in the database that has to be a string type field of around 4000 characters.

So naturally I setup the field as
type: varchar
length: 4000

However when I try to put any text in this field I find that I can put no more than 1023 characters of ascii text in there.

To check if this was a max record length prob I setup a test table with only 2 fields:
ID: int, PK, Identity
longVarchar: varchar, 4000

and tried to put some ascii text into the field called longVarchar. Again the most I could put in was 1023 characters!

Thinking that it could just be that SQL svr box that was wacky, I tried it on another one with the same result.

I have tried using other field types (nvarchar, char) and have found that they all could only hold 1023 characters max, no matter what how high I defined the size of the field.

Try it out yourselves and see if you get the same result. Any useful suggestions would really be appreciated.

Display Over 256 Characters For VARCHAR(3500) Field

Jan 12, 2006

Hopefully, someone can help me.
I am working with a database that contains multiple fields within the tables that are being used for Clinical notes. The fields are defined as VARCHAR(3500). But when I try to extract data (either through Query Analyzer or Crystal Reports), only the first 256 characters are displayed. I ran a query to give me the length of the maximum entry size which returned 2722 characters, yet only 256 are displayed.

How do I go about extracting ALL of the data from this field? Any help is much appreciated.

Using A Varchar Versus A Nvarchar Causes Hungarian Characters To Be Displayed Incorrectly On The Webpage.

I have a hungarian character which looks like a lower case o with two single quotes on top of it --> Å‘

I have this character stored in two table the datatype of the column where this is stored at is varchar in one table and nvarchar in the other. When I try to view the field in enterprise manager the character appears as it should in the 2 tables, but when I use a jsp page deployed on weblogic to look at this character the one stored in the column of type varchar displays perfectly, but the table in which the column is nvarchar the character on the jsp page appears as a Q instead.

Any inputs on how to correct this issue will be much appreciated. Any changes to the character set on the html / jsp pages has no affect on the result.

When I look at the field it appears some of the entries have special characters appended at the end, I see a box after the value.

How can I remove all speical characters and then convert that field to an int?

In my application I must store over 16000 character in a sql table field . When I split into more than 1 field it gives "unclosed quotation mark" message.
How can I store over 16000 characters to sql table field (only one field) with language specific characters?
 
Thanks

Hello,

We are using Exec(@sql) with @sql varchar(8000), but 8000 is not enough. Like query get cut off in the middle of the script. We need more than that. Is there any way to store more than 8000 characters in the variable ?
We use SQL Server 7.

Thanx in advance.
