Hi 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
Chak.
is 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 ?
For 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!
Hi,A query is exceeding the length of varchar and nvarchar variable.Because I'm picking the data from each record from table and giving itto the query.suggest me some way to do it.sample query:SELECT P1.*, (P1.Q1 + P1.Q2 + P1.Q3 + P1.Q4) AS YearTotalFROM (SELECT Year,SUM(CASE P.Quarter WHEN 1 THEN P.Amount ELSE 0 END) ASQ1,SUM(CASE P.Quarter WHEN 2 THEN P.Amount ELSE 0 END) ASQ2,SUM(CASE P.Quarter WHEN 3 THEN P.Amount ELSE 0 END) ASQ3,SUM(CASE P.Quarter WHEN 4 THEN P.Amount ELSE 0 END) AS Q4FROM Pivot1 AS PGROUP BY P.Year) AS P1GO---> even the P.QUARTER .... FIELD NAME IS BEING GENERATEDDYNAMICALLY.MY QUERY IS EXCEEDING VARCHAR AND NVARCHAR LIMIT.THANX IN ADV.
I am executing a SELECT statement that has about 500 characters of literal characters concatenated with the contents of a field from a table. I am then storing the result to be run as dynamic SQL. I am finding that when run this as select statement in query analyzer, the last part of the literal gets truncated. When I run it as a cursor and store it in a varchar(1000) variable and print the variable everything works fine. In addition when I put the select statement in a stored procedure and return this to a ADO recordset, the resultset is fine as well. But running the stored procedure in query analyzer truncates the results as well. The issue seems to be getting the results of the SELECT in query analyzer. Even running the stored procedure in the SQL area of Enterprise Manager returns a proper result. Has anyone heard of a maximum return from a select in query analyzer?
I 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
Hi i got errro mess "Invalid length parameter passed to the substring function" from this below. Anyone how can give me a hint what cause this, and how i can solve it? if i remove whats whitin thoose [] it works, i dont use [] in the code :) colums: VLF_InfectionDestination is nvarchar 254

We ran into a problem loading access where tables where if we did notselect the property allow zero length we got an error message whenloading data with some empty values.We are now ramping up SQL server and the question came up will SQLserver have the same problem with empty data values.Is there an SQL server equivalent to allow zero length?
Hi all - am in a bit of a quandry over this one!My application is all up and running - it's an despact & accounts app - I've missed one thing though - the ability to deal with half pennies (or half cents for those of you over the pond ;)) All of my tables are set up as decimal (19,2) along with all the params in my stored procs (a lot!). Is there an easy way to change all of these in 1 swoop? Thanks in advance, Stephen.
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?
Hi, I am sending the output of a query to a file and unfortunately every row is containing only a certain number of characters. My query has rows having length of 1500 characters for each row. When I get the query and send it to a file I am seeing only the first 250 characters for each row instead of 1500 characters.
I will be grateful if anyone can help me suggesting a solution for this problem.
SQL Intrduction book on page 269 says that the max.amount of data contained in a single row is 8060 bytes. But I have no difficulty creating a table with two varchar 8000 columns. How can this be ? Can somebody explain how to interpret the statement about max.8060 bytes please? Thanks.
Hi Has anyone come across SQL Server giving errors like A row on 'page 52995' was accessed that has illegal length of 0 in database? I believe that it is due to some data on the page has been corrupted. Is there a way to prevent such problem? Can daily backup be able identify such problem?
Hi 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?? What is the solution? Thanks
i have problem regarding the row length and varchar. my problem is on every new row i have +6 more character on one of my field then the last record. and BOL says i can only have 8060 character per row. What i can not use the full lenght of varchar(8000) on field.
I am creating a piece of code to create audit tables based on my current tables. I'm using the info in sysobjects to get this done, but I have one problem. I can't seem to find the actual lenght of a column, I tried with the systypes.length, but that was obviously not what I needed. Does someone know how (or where) I can retrieve the length that I need?

Running transactional replication, dedicated server for distributor. While performance in terms of latency is excellent (usually 1 sec, almost never higher than 4) the disk queue length on the distributor is extremely high (over 6 usually). Is this typical? On any other server I would be very concerned, but cpu and memory usage are excellent and as said, latency is good. what is recommended config for distributor? others see high queue length?
I have a table this is populated by a flat file. In the desc field from the flat file some of the data is very long up to 150 characters in length. I have to export this data after some transformations to a fixed width file. I need to check the length of the data in the desc field and any thing that is to long needs to be put in a desc2 field, however any values in desc that are shorter than 36 characters in length needs to have spaces padding it up to 36 characters as well as the desc2 field. Any help would be great. I am not the best T-SQL programmer in the world and have limited time to get this done.
