A Question About Varchar Parameters
May 24, 2006
I've created a stored procedure that takes a varchar(10) as a parameter. However calling this stored procedure from an ASP page, with a string of greater length, generates an error. However this does not happen in Query Analyzer (it simply truncates the string to 10 characters). I was under the previous impression that this truncation was implicit, but now it seems that it is not. Can someone please give me a quick overview of how to work around this issue (is there an SQL setting I can flip on). I know I could pre-truncate every value in my page, but that seems like a design nightmare (seeing as how I would need to know the size of every varchar parameter in every stored procedure old and new, also I'd like to be able to simply increase the size of the data field in the table, at a later point, without having to match it up in every stored procedure and ASP page ).
P.S. I am using SQL Sever 2000

I am using version 9.00.2047.00 SP1 of Visual Studio 2005.
Using ADO.NET, I have been unable to get the Execute SQL task to successfully return the value of an output parameter defined as varchar or nvarchar when the value is null. No other data types seem to have this problem, including the sql_variant data type.
Here is the stored procedure I am calling:
create proc spx
@in int = null output,
@vc nvarchar(10) = null output,
@dt datetime = null output
as
select
@in = null,
@vc = null,
@dt = null
return
The variables to which the three output parameters return their values have a data type of Object. The task runs fine when the integer or datetime parameters are used, and the variables can be identified as null using IsDBNull. But as soon as the nvarchar (or varchar) parameter is included, the task fails with this message:
"The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 1 ("@vc"): Data type 0xE7 has an invalid data length or metadata length."
I have seen a couple of postings that sound similar to this problem, but so far I have found no resolution. Any advice would be much appreciated.
Thanks,
Ron Rice

I have the following code and i want to passed more than one value:
DECLARE @myvendedor AS varchar(255)
SET @myvendedor = '87,30'
print @myvendedor
SELECT top 10 ECOM.COM1,* from ecom (nolock) WHERE ecom.PORVEND=1 AND ECOM.VENDEDOR IN (@myvendedor)
Table Field ECOM.VENDEDOR is Numeric(4,0)
This error occur:
87,30 --Result of PRINT
Msg 8114, Level 16, State 5, Line 6
Error converting data type varchar to numeric.
I change :
DECLARE @myvendedor AS numeric(4,0)
and this error appear:
Msg 8114, Level 16, State 5, Line 2
Error converting data type varchar to numeric.

I have looked far and wide and have not found anything that works to allow me to resolve this issue.
I am moving data from DB2 using the MS OLEDB Provider for DB2. The OLEDB source sees the column of data as DT_TEXT. I setup a destination to SQL Server 2005 and everything looks good until I try and run the package.
I get the error:
[OLE DB Source [277]] Error: An OLE DB error has occurred. Error code: 0x80040E21. An OLE DB record is available. Source: "Microsoft DB2 OLE DB Provider" Hresult: 0x80040E21 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".
[OLE DB Source [277]] Error: Failed to retrieve long data for column "LIST_DATA_RCVD".
[OLE DB Source [277]] Error: There was an error with output column "LIST_DATA_RCVD" (324) on output "OLE DB Source Output" (287). The column status returned was: "DBSTATUS_UNAVAILABLE".
[OLE DB Source [277]] Error: The "output column "LIST_DATA_RCVD" (324)" failed because error code 0xC0209071 occurred, and the error row disposition on "output column "LIST_DATA_RCVD" (324)" specifies failure on error. An error occurred on the specified object of the specified component.
[DTS.Pipeline] Error: The PrimeOutput method on component "OLE DB Source" (277) returned error code 0xC0209029. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.
Any suggestions on how I can get the large string data in the varchar column in DB2 into the varchar(max) column in SQL Server 2005?

I am trying to create a store procedure inside of SQL Management Studio console and I kept getting errors. Here's my store procedure.
Code Block
CREATE PROCEDURE [dbo].[sqlOutlookSearch]
-- Add the parameters for the stored procedure here
@OLIssueID int = NULL,
@searchString varchar(1000) = NULL
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
IF @OLIssueID <> 11111
SELECT * FROM [OLissue], [Outlook]
WHERE [OLissue].[issueID] = @OLIssueID AND [OLissue].[issueID] = [Outlook].[issueID] AND [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
ELSE
SELECT * FROM [Outlook]
WHERE [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
END
And the error I kept getting is:
Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 18
The data types varchar and varchar are incompatible in the modulo operator.
Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 21
The data types varchar and varchar are incompatible in the modulo operator.
Any help is appreciated.

For the life of me I cannot figure out why SSIS will not convert varchar data. instead of using the table to table method, I wrote a SQL query so that I could transform the datatype ntext to varchar 512 understanding that natively MS is going towards all Unicode applications.
The source fields from Access are int, int, int and varchar(512). The same is true of the destination within SQL Server 2005. the field 'Answer' is the varchar field in question....
I get the following error
Validating (Error)

Error 0xc02020f6: Data Flow Task: Column "Answer" cannot convert between unicode and non-unicode string data types.

DTS used to be a very strong tool but a simple import such as this is causing me extreme grief and wondering of SQL2005 is ready for primetime. FYI SP1 is installed. I am running this from a workstation and not on the server if that makes a difference...
Any help would be appreciated.

I have a table that contains a lot of demographic information. The data is usually small (<20 chars) but ocassionally needs to handle large values (250 chars). Right now its set up for varchar(max) and I don't think I want to do this.
How does varchar(max) store info differently from varchar(250)? Either way doesn't it have to hold the container information? So the word "Crackers" have 8 characters to it and information sayings its 8 characters long in both cases. This meaning its taking up same amount of space?
Also my concern will be running queries off of it, does a varchar(max) choke up queries because the fields cannot be properly analyzed? Is varchar(250) any better?
Should I just go with char(250) and watch my db size explode?
Usually the data that is 250 characters contain a lot of blank space that is removed using a SPROC so its not usually 250 characters for long.
Any insight to this would be appreciated.

Hi all,
From the "How to Call a Parameterized Stored Procedure by Using ADO.NET and Visual Basic.NET" in http://support.microsft.com/kb/308049, I copied the following code to a project "pubsTestProc1.vb" of my VB 2005 Express Windows Application:
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlDbType
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim PubsConn As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS;integrated security=sspi;" & "initial Catalog=pubs;")
Dim testCMD As SqlCommand = New SqlCommand("TestProcedure", PubsConn)
testCMD.CommandType = CommandType.StoredProcedure
Dim RetValue As SqlParameter = testCMD.Parameters.Add("RetValue", SqlDbType.Int)
RetValue.Direction = ParameterDirection.ReturnValue
Dim auIDIN As SqlParameter = testCMD.Parameters.Add("@au_idIN", SqlDbType.VarChar, 11)
auIDIN.Direction = ParameterDirection.Input
Dim NumTitles As SqlParameter = testCMD.Parameters.Add("@numtitlesout", SqlDbType.Int)
NumTitles.Direction = ParameterDirection.Output
auIDIN.Value = "213-46-8915"
PubsConn.Open()
Dim myReader As SqlDataReader = testCMD.ExecuteReader()
Console.WriteLine("Book Titles for this Author:")
Do While myReader.Read
Console.WriteLine("{0}", myReader.GetString(2))
Loop
myReader.Close()
Console.WriteLine("Return Value: " & (RetValue.Value))
Console.WriteLine("Number of Records: " & (NumTitles.Value))
End Sub
End Class
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
The original article uses the code statements in pink for the Console Applcation of VB.NET. I do not know how to print out the output of ("Book Titles for this Author:"), ("{0}", myReader.GetString(2)), ("Return Value: " & (RetValue.Value)) and ("Number of Records: " & (NumTitles.Value)) in the Windows Application Form1 of my VB 2005 Express. Please help and advise.
Thanks in advance,

I have a SSRS report with four parameters,and I want to be able to enter information for two of the parameters and run the report opposed to all four of them. However, when I select allow blanks and only select the parameters that I want to run the report by, the report come back blank..Essentially, I want to be able to the run report by different parameters without having to enter information for all parameters at the same time.

Hey,
I was doing some research on how SQL stores data on disk.
MSDN states that when storring a varchar, only the length of the data itself is used plus two bytes.
So, if you store "car" in a VarChar(50) it will take 5 bytes.
But when you store "car" in a VarChar(500) it will also take 5 bytes.
What is the reason users should define the parameter lenght?
Can you use VarChar(8000) whole the time, without any drawback?
Thanks

Hi,
I have an app in C# that executes a query using SQLCommand and parameters and is taking too much time to execute.
I open a SQLProfiler and this is what I have :
exec sp_executesql N' SELECT TranDateTime ... WHERE CustomerId = @CustomerId',
N'@CustomerId nvarchar(4000)', @CustomerId = N'11111
I ran the same query directly from Query Analyzer and take the same amount of time to execute (about 8 seconds)
I decided to take the parameters out and concatenate the value and it takes less than 2 second to execute.
Here it comes the first question...
Why does using parameters takes way too much time more than not using parameters?
Then, I decided to move the query to a Stored Procedure and it executes in a snap too.
The only problem I have using a SP is that the query can receive more than 1 parameter and up to 5 parameters, which is easy to build in the application but not in the SP
I usually do it something like
(@CustomerId is null or CustomerId = @CustomerId) but it generate a table scan and with a table with a few mills of records is not a good idea to have such scan.
Is there a way to handle "dynamic parameters" in a efficient way???

Hello:
I just recently bumped into this problem and I think I know what's causing it. This is the setup:
Report Parameters: FromDate, ToDate, DivisionalOffice, Manager, SalesRep
dsCalendarEvents Parameters: FromDate.Value, ToDate.Value, DivisionalOffice.Value,
dsDivisions Parameters: N/A
dsManager Parameters: DivisionalOffice.Value
dsSalesRep: DivisionalOffice.Label
When I query the ReportServices WS and scan the parameter dependencies for SalesRep it says there are four dependencies: FromDate, ToDate, DivisionalOffice and Manager!!!
If I change "dsSalesRep" to use "DivisionalOffice.Value" the ReportingServices WS parameter dependency scan returns only one dependency for "SalesRep" parameter!!!( This is the correct behavior )
Has anybody seen this behavior and more importantly, is there a work around?
Regards,

Hello all,
Given:
string commandText = "Categories_Delete";SqlCommand myCommand = new SqlCommand(commandText, connection);myCommand.CommandType = CommandType.StoredProcedure;
Is there a reason NOT to use myCommand.Parameters.AddWithValue("@CategoryID",CategoryID); I'd prefer to use that over myCommand.Parameters.Add("@CategoryID", SqlDbType.Int, 4).Value = CategoryID; as I have these functions being created dynamically and hope to get away from a big lookup to try to convert System.Types into SqlDbTypes. [shudder]
It seems that ADO.NET makes an implicit conversion to the valid type. If this is correct then I can move on fat dumb and happy. Anyone have any good insight?
Thanks,

I've only just discovered this! Shame on me.
So this is the future? 268 thousand times more space without the headache of text columns (and not being able to use them as parameter types for long csv's) are finally a thing of the past? Could it be? http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=66929
I only discovered it because I ran into a problem trying to create a trigger and so then I learnt that:
"SQL Server 2005 does not allow for text, ntext, or image column references in the inserted and deleted tables for AFTER triggers. However, these data types are included for backward compatibility purposes only. The preferred storage for large data is to use the varchar(max), nvarchar(max), and varbinary(max) data types. Both AFTER and INSTEAD OF triggers support varchar(max), nvarchar(max), and varbinary(max) data in the inserted and deleted tables."
http://msdn2.microsoft.com/en-us/library/ms191300.aspx
Has anyone experienced any problems converting over from text to varchar(max)?

Hi guys,
I'm new to MS-SQL 2005, I will ask you a bunch of questions and I hope I will not be too boring hehe !
I learned that in MS-SQL 2005, you can now use varchar(max), my question is why not always use varchar(max) since it will automatically use only the space needed ? Is there an advantage in specifying a size other than max when you use a varchar for an entry that can vary in length alot ?
Thank you very much,

Is it better to make these columns text columns?
The 2 varchar(2000) columns do not need to be searched, but many of the other columns in that table do need to be searched.
The varchar(4000) column has a full text index on it.

I am running a database to collect the results of multiple surveys. Results are stored in an UNPIVOTED form (see example)...SurveyID RespondantID QuestionID Answer
=========================================================
1 1 1 X
1 1 2 Y
1 1 3 Z
1 2 1 R
1 2 2 S
1 2 3 T
Most of the results are integer responses (from multiple choice questions) but some are free text. For effecieny purposes I split the answers into two tables (one where answer = smallint, the other where answer = varchar(500)) but this is causing a few problems pulling data out of the database.
Basically all I want to know if once the table starts collecting thousands, or even tens of thousands of responses then it was the right idea to split the tables (in terms of table size and search speed), or in actual fact it wont make any (noticeable) difference.
Thanks!

zzzz{eeeeee}
like above values i am storing into the column. Now i want to use only the value which is inside the brackets { }. Values inside the brackets are not fixed length but allways we use the brackets.
Please let me know if you have any idea.
I tried using the right(value,4).,.. but this is only for the fixed size. but like i said my situation is different length.please let me know if you have any idea.
