A query is exceeding the length of varchar and nvarchar variable.
Because I'm picking the data from each record from table and giving it
to the query.
suggest me some way to do it.
sample query:
SELECT P1.*, (P1.Q1 + P1.Q2 + P1.Q3 + P1.Q4) AS YearTotal
FROM (SELECT Year,
SUM(CASE P.Quarter WHEN 1 THEN P.Amount ELSE 0 END) AS
Q1,
SUM(CASE P.Quarter WHEN 2 THEN P.Amount ELSE 0 END) AS
Q2,
SUM(CASE P.Quarter WHEN 3 THEN P.Amount ELSE 0 END) AS
Q3,
SUM(CASE P.Quarter WHEN 4 THEN P.Amount ELSE 0 END) AS Q4
FROM Pivot1 AS P
GROUP BY P.Year) AS P1
GO
---> even the P.QUARTER .... FIELD NAME IS BEING GENERATED
DYNAMICALLY.
we can use 'sp_executesql' to execute any statemens. I have made a search and people, seems, need the dynamic sql only to process some table/cloumn unknown in advance. My idea is that the dynamic SQL feature is ideal for passing blocks of code (aka delegates). Particularily, you may require to execute different procedures under some acquired locks. A procedure would acquire the locks, execute the code and release the locks. The problem is, however, that I cannot find the specification for the variable length parameters. It seems not feasible for SPs. Nevertheless, the 'sp_executesql itself does accept the variable number of parameters. How? Can we look at the defenition?
I'm new to SQL Server. I installed a copy of 6.5 on my server and set it up today. I received a db from a colleague and have been unable to find out what the variable types and lengths are. This may be very easy but I need to know.
Morning All,Can I have some help with this one please, I am having to make a fixed length text file based on information from the DBDeclare @EDIString varchar(MAX)Declare @RecordType varchar(2)Declare @RegistrationMark varchar(7)Declare @Model_Chassis varchar(11)Declare @LocationCode Varchar(4)Declare @MovementDate varchar(8)Declare @IMSAccountCode varchar(5)Declare @MovementType varchar(8)Declare @NotUsed1 Varchar(28)Declare @NotUsed2 varchar(7)Select @RecordType = RecordType, @RegistrationMark = RegistrationMark, @Model_Chassis = Model_And_Chassis, @LocationCode = LocationCode, @MovementDate = MovementDate, @IMSAccountCode = IMSAccountCode, @Movementtype = MovementTypeCode from Fiat_OutBoundOnce I have selected the information from the DB I need to ensure that each field is the correct length. I therefore want to pass the variable and the length of the variable into a function to return the correct length.So if location Code = 'AB' this needs to be four characters long so want to pass it into a function and return 'AB 'As I need to do this for 70+ variables is there an easy way to obtain the length of the collation for the variable?regardsTom
I have a requirement to import a file of rows containing fixed length data. The problem is that each row can be one of 5 different formats (i.e. different columns) -- where the "type" of row is indicated by the first two characters of the row. Each row gets inserted into its own table.
Could I use a simple Conditional Split to route the rows? Or is the split for routing similiar rows? Anyways, problems are never this simple...
In addition, each "grouping" of rows is related. The "first" row is considered the "primary" row (and gets a row id via IDENTITY, whereas the remaining rows in the group are "secondary" rows and have foreign key references back the the primary rows id.
Given (using spaces to separate columns and CrLf to show "grouping"):
So, the first 3 lines are all related to a MSFT record which needs to be spread across multiple tables. The next three lines are all related to AAPL, And the next FOUR lines (yes, each record can have zero, one, or more secondary rows) are related to CSCO.
(If this is still not clear, all the "01" rows will be written to [Table1] with each row having an IDENTITY value. All the "02" rows will be written to [Table2] the a FK pointing to the correct [Table1] row. All the "03" rows will be written to... and so on.
I am running SQLServer 2000 to parse and store records in the EDIX12 format. This consists of variable length delimited records which I am passing to the "transforms" tab to process with VBScript.
The problem is though each segment has a defined number of fields, N, the standard states that if the final M fieds are empty/blank they are not to be sent. Thus, a segment defined to have 20 fields may have 6 the first time I see it, 13 the next time, etc. To access the columns in VBScript I use DTSSource("Col001"). This works as long as the columns are there, but gives an error when they are not. Is there a parameter telling me how many columns are defined? Or is there something akin to IFEXISTS("Colxxx") or exceptions?
How can I handle this situation? One suggestion has been to pass the entire segment to the Transforms section and break it up there.
Finally, what resources can yuo point me to for reference? I'd like to get good at using DTS since my client wants their project written for it.
I have this doubt and want to be sure if my thinking is correct.
Lets consider 2 tables one with Fixed length columns (char) and other table with Variable length columns (Varchar).
The table with fixed length column will always allocate same size within a Page however, table with variable length column will allocate actual length of data within a page.
I think that updates happening on table with fixed length columns will have more possibility of InPlace updates at least from data length perspective, however updates on table with variable length columns will have more split updates from data length perspective.
I'm having problems with SQL 2005 Express Edition exceeding the maximum memory limit. I hard set the minimum to 100 and the maximum to 500, but the server is currently using over 800MB and is causing the system to page. Has anyone had any experience with similar issues and if so how did you resolve them.
We needed to detach a database that contained a target ServiceBroker service and wanted to do this without impacting the rest of our system. The idea was the ServiceBroker would enqueue message to this service to be pickedup when the database was re-attached. Our sequence to do this was:
1. Disable the queue on the target service forcing ServiceBroker to queue in the initating side transmission queue.
2. Detach the database.
3. Re-attach the database.
4. Re-enable the queue
Messages sent to the service have a specified LIFETIME. What appeared to happen was that messages were being stored in the transmission queue as expected but on hiting the LIFETIME period they were being removed from the transmission queue and were therfore "lost".
Has anyone else experienced this or can anyone suggest what we are doing wrong.
Incidentally, beaware that detaching a database will disable ServiceBroker in that database when it is re-attached - we discovered that one the hard way :-)
This is a question that I have not had an opportunity to test. Was wanting to know if anyone in the SQl world knows the answer. In SQL 2K and 2005 your rolls are limited to 8060 bytes without using varchar(MAX). My question is do you have to specify varchar(max) before your roll can exceed 8060 or does SQL 2005 exceed without specifing varchar(Max). Also does SQL 2005 expand it across multiple pages automatically. Please assist if you can.
Okay, I know the maximum size limit on a database in SQL 2005 Express is 4GB, but what happens when you exceed that limit? I can't seem to find much info on that topic. What kind of error return would you get from a stored procedure attempting to do an insert that will exceed the 4GB limitation? Also what factors go into that maximum size, factors that might not be completely obvious of course?
We run std 2008 r2. I'm trying out the commandtimeout property of an oledb source. I set it to 30 expecting 30 seconds. if connection and or execution exceed that threshold, will the pkg fail? Either way is there a way I can detect that the threshold was exceeded?
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!
I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:
DECLARE @DV INT; SET @DV = (SELECT MAX(DateValue) FROM tblTG); DECLARE @PV INT; SET @PV = @DV - 1;
I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:
DECLARE @DV INT; SET @DV = ?; DECLARE @PV INT; SET @PV = @DV - 1;
I have almost 50 references to these parameters in the query so a substitution would be helpful.
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
SELECT TOP 10 tb_AVVirusLog.VLF_VirusName, COUNT(tb_AVVirusLog.VLF_VirusName) AS number FROM tb_AVVirusLog INNER JOIN __CustomerMachines002 ON tb_AVVirusLog.CLF_ComputerName = __CustomerMachines002.FalseName WHERE (CONVERT(varchar, tb_AVVirusLog.CLF_LogGenerationTime, 120) BETWEEN @fyear + @fmonth + @fday AND @tyear + @tmonth + @tday) AND (__CustomerMachines002.folder_id = @folderId) [OR (CONVERT(varchar, tb_AVVirusLog.CLF_LogGenerationTime, 120) BETWEEN @fyear + @fmonth + @fday AND @tyear + @tmonth + @tday) AND (tb_AVVirusLog.VLF_InfectionDestination LIKE N'%@%')] GROUP BY tb_AVVirusLog.VLF_VirusName HAVING (NOT (tb_AVVirusLog.VLF_VirusName LIKE N'cookie')) ORDER BY COUNT(tb_AVVirusLog.VLF_VirusName) DESC
how do I get the variables in the cursor, set statement, to NOT update the temp table with the value of the variable ? I want it to pull a date, not the column name stored in the variable...
create table #temptable (columname varchar(150), columnheader varchar(150), earliestdate varchar(120), mostrecentdate varchar(120)) insert into #temptable SELECT ColumnName, headername, '', '' FROM eddsdbo.[ArtifactViewField] WHERE ItemListType = 'DateTime' AND ArtifactTypeID = 10 --column name declare @cname varchar(30)
do i need to nest a query in RS if i want a calculated column to be compared against a multi value variable? It looks like coding WHERE calcd name in (@variable) violates SQL syntax. My select looked like
SELECT ... ,CASE enddate WHEN null then 1 else 0 END calcd name FROM... WHERE ... and calcd name in (@variable)
Hi all, Sorry if this is the wrong place to ask but I have tried a few places with no joy. In SQL when querying using a variable I can use @ symbol. ie: SELECT COUNT(*) FROM dbo.Persons WHERE SocialSecurityNumber = @SocialSecurityNumber Then in say visual web developer this would prompt me to enter the variable for @SocialSecurityNumber This all works perfect. My issue is when I query a DB2 DB directly say SELECT COUNT(*) FROM DB2.table WHERE (MMITNO = @MMITNO) I get ther error "Column @MMITNO does not exist" My question is. What symbol do I use to represent variable in DB2. In SQL it is @ ..I think these symbols are known as sigils Please Help Ray..
Is it possible to use a column name variable in a Select Statement for a column name?For example I have a dropdown with FName,LName,Phone and a text box. The user can select the field to search and the criteria will go into the text box. The problem is the select doesn't like a variable for the field name. I have tried both a standard variable and a Case statement (see below). This is being used in a Stored Procedure with MSSQL. The actual select is much more complicated than this but it gets the point across. Thanks for your help in advance@Field as varchar( 50),@Value as varchar (50)SELECT *FROM customersWHERE @Field = @ValueORSELECT *FROM customersWHERE CASE WHEN @Field = 'Fname' THEN Fname = @Value END, CASE WHEN @Field = 'Lname' THEN Lname = @Value END, CASE WHEN @Field = 'Phone' THEN Phone = @Value END;
