Data Access :: Validation For Length Of The Character Data Types
Jun 10, 2015I Have a table with #Sample like below
=================================
#Sample
id int,
SSN varchar(20),
State varchar(2)
Sample Data:
ID SSN STATE
1 999-000-000 AB
2 979-000-000 BC
3 995-000-000 CD
=================================
We used filter logic based on the SSN & State.
We are passing these values through variables like
Declare @State varchar(2)
Declare @SSN varchar(20)
While run time these values are lets suppose @SSN = '999-000-000' & @State='ABC'
Now the Result is displayed with the state data Like 'AB' only.
Output: 1 999-000-000 AB
instead it should give system generated error.
Here I have 2 Questions:
1. Why it is taking 1st 2 Charecters?
2. Why it does not have any system generated for length?
I can do validation with Length function for these 2 variables however if have 100 variables then it should not feasible case. So, what is the reason behind?
T-SQL (SS2K8) :: Procedure Parameter Length Declaration Less Than Column Length?
Jun 30, 2014is there any way or a tool to identify if in procedure the Parameter length was declarated less than table Column length ..
I have a table
CREATE TABLE TEST001 (KeyName Varchar(100) ) a procedure
CREATE PROCEDURE SpFindNames ( @KeyName VARCHAR(40) )
AS
BEGIN
SELECT KeyName FROM TEST001
WHERE KeyName = @KeyName
END
KeyName = @KeyName
Here table Column with 100 char length "KeyName" was compared with SP parameter "@KeyName" with length 40 char ..
IS there any way to find out all such usage on the ALL Procedures in the Database ?
BlobColumn.GetBlobData() With Data Length &&> Integer Length (32767)
Mar 27, 2008For those of you who would like to reference my exact issue, I'm dealing with the RSExecution SSIS package at the "Update Parameters" data flow task, at the Script Component.
The script tries to split parameter data into name and value. Unfortunately, I have several reports that are passing parameters that are very large. One example has over 65,000 characters all in the normal "¶mname=value&parm2=value..." format.
The code in the script works fine until it gets to one of these very large parameter sets. I have figured out what is causing the issue. Here's some code:
Dim paramBlob as Byte()
paramBlob = Row.BlobColumn.GetBlobData(0, Row.BlobColumn.Length)
The second parameter of the .GetBlobData function takes an INTEGER as its count! Therefore, no matter what kind of datatype I pass to the string that the script will later split, it will be limited to 32767 characters.
THIS IS A PROBLEM!!!
Does anyone know a workaround for this issue? I need all of the parameter data to be reported, and I would hate to have to skip over rows like this. Also, if I'm missing something, please fill me in!
Thanks for your help in advance,

CommandParameters.length Don't Match Parametervalues.length
Feb 24, 2008I am trying to narrow down this problem. Basically, I added 3 columns to my article table. It holds the article id, article text, author and so on. I tested my program before adding the additional field to the program. The program works fine and I can add an article, and edit the same article even though it skips over the 3 new fields in the database. It just puts nulls into those columns.So, now I have added one of the column names I added in the database to the code. I changed my businesslogic article.vb code and the addarticle.aspx, as well as the New article area in the addartivle.aspx.vb page. The form now has an additional textbox field for the ShortDesc which is a short description of the article. This is the problem now: The command parameters.length is 9 and there are 10 parameter values. Right in the middle of the 10 values is the #4 value which I inserted into the code. It says Nothing when I hover my mouse over the code after my program throws the exception in 17 below. Why is command parameters.length set to 9 instead of 10? Why isn't it reading the information for value 4 like all the other values and placing it's value there and calculating 10 instead of 9? Where are these set in the program? Sounds to me like they are hard coded in someplace and I need to change them to match everything else. 1 ' This method assigns an array of values to an array of SqlParameters.2 ' Parameters:3 ' -commandParameters - array of SqlParameters to be assigned values4 ' -array of objects holding the values to be assigned5 Private Overloads Shared Sub AssignParameterValues(ByVal commandParameters() As SqlParameter, ByVal parameterValues() As Object)6 7 Dim i As Integer8 Dim j As Integer9 10 If (commandParameters Is Nothing) AndAlso (parameterValues Is Nothing) Then11 ' Do nothing if we get no data12 Return13 End If14 15 ' We must have the same number of values as we pave parameters to put them in16 If commandParameters.Length <> parameterValues.Length Then17 Throw New ArgumentException("Parameter count does not match Parameter Value count.") 18 End If19 20 ' Value array21 j = commandParameters.Length - 122 For i = 0 To j23 ' If the current array value derives from IDbDataParameter, then assign its Value property24 If TypeOf parameterValues(i) Is IDbDataParameter Then25 Dim paramInstance As IDbDataParameter = CType(parameterValues(i), IDbDataParameter)26 If (paramInstance.Value Is Nothing) Then27 commandParameters(i).Value = DBNull.Value28 Else29 commandParameters(i).Value = paramInstance.Value30 End If31 ElseIf (parameterValues(i) Is Nothing) Then32 commandParameters(i).Value = DBNull.Value33 Else34 commandParameters(i).Value = parameterValues(i)35 End If36 Next37 End Sub ' AssignParameterValues38 39 40 41

The logic being that multiple and consecutive occurrences of the special character, here - pipe , should be replaced by a single special character.

Read Chinese Character From SQL(SQL Server 2005) Database Table Column And Display Chinese Character
Feb 1, 2008Hi!
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());

Max Record Length For DTS?
Apr 26, 2001Hi folks,
I'm trying to load a flat file (text) into a table with 83 columns in it. The record length on the flat file is 251 characters long. For some reason when running the DTS import utility, DTS can't read the past the 142 character on the flat file, it spills on to the next line. The red bar is set on the 143 character when i use the fix field options in DTS import. Can the red bar be moved out further? Or is there a max field length using DTS?
anyone out there that can help?

Max. Length Of A Row In The Query.
Jul 13, 2001Hi Guys
I am having a problem with the execution of a query.This is how it is working,if i include all the clounms(26 columns) for the output of 34,000 records it is taking around 4 Min. but if i exclude one column or reduce the size of the column i.e from text to varchar(100) it is taking 23 Sec.
If i am trying to change the size of the column from varchar(100) to varchar(150) it is taking the same time i.e, 4 Min.
Looking at this i am wondering if there are any system setting where we can increase the size of the rows for the out put or are there any other things i have to look at to increase the speed of the Query.
Did anyone come across this problem.
Any help is appriciated.
Thanks

I will be grateful if anyone can help me suggesting a solution for this problem.

When writing a stored procedure,sometimes the line of sql code could be very long and be more than 128 caracthers.
I got an error message saying that the code is vey long and the maximum is 128.
But at the same time, this is erratic in MSSQL server because it works sometimes even with a line of code of more than 800 caracters...
Have you ever experienced the same problem??
