Frror: 4000 Max String Literal In Expression For Datareader Component
Apr 15, 2006
Hi, I have a datareader component of which i am dynamically setting its sqlcommand statement with expression (click the background of dataflow > properties > expressions). Now my sql select statement has about 600 fields so that makes my expression statment "select field1, field2, .....from table1 where field2 >=" + @[User::dateforfield2] but when i evalute the expresssion (which is right), i get the error: A string literal in the expression exceeds the maximum allowed length of 4000 character and i think its because of the fields in my select statment causing my string literal to grow more than 4000 characters. Is there any way to increase the max string literal for expressions. Please help.
I have a package that has a data lfow task. this task imports data from a db2 database (using the IBM Ole DB provider fro db2) and adds it to sql server database table. This package was created on the server. then though version control (using TFS source control) I check out the package on my local machine. and when I open the package I get the foll 3 errors.
Error 1 Validation error. Import Account Num from BMGP_BDR: DTS.Pipeline: The component metadata for "component "DataReader Source" (1113)" could not be upgraded to the newer version of the component. The PerformUpgrade method failed.

I have a package which reads an Access file from a folder. My connection manager to this file is .NET providers for OledbMicrosoft Jet 4.0 OLE DB Provider.
Package works from my computer. But when I execute it on the server as a SQL Agent job, I get
The component metadata for "component "DataReader Source" (1) could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
I copied the mdb file to a folder on the server which my packages have no problem reading data from.
My packages run under the same domain account as defined in proxies.
I have a package with an input column that is varchar(8000).
I want to strip the first byte off of this column and put it in one result column and the remainder of the field I want to go to a second column. If the input column is an empty string, I want to return NULL.
Pulling the first byte off works fine, no issues, however putting the remainder of the input column into an output column is giving me a little trouble.
The expression passes muster but I get the warning that I will be truncating the column at 4000 bytes.
In actuality, I don't care if the result column is truncated after 4000 bytes. I find the second solution to be a bit clunky and I'm wondering if anyone can give me a reason why the first solution won't evaluate but the second will?
Hi, I want to convert literal string to unicode before insert into the database. and after insertion i want to retrive this value from data base and convert back to literal string. pls tell me how to incode and decode literal string to unicode and from unicode to literal string.
The proc below does two queries that are functionally identical. The only difference is that one LIKE 'foo%', and the other uses LIKE @searchText, where @searchText = 'foo%'.
But the first does an index seek, and the second does an index scan -- and it makes a big difference in performance. (Timing stats are below.)
How can I make the second query seek instead of scanning?
Attempting to create a data flow task to copy data from AS/400 (DB2) to SQL2005, using an existing System DSN ODBC connection defined on the SQL2005 host.
Problem:
When adding the DataReader Source component to the package, I cannot assign the Connection Manager. Designer issues the error message:
"The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."
Editing the DataReaderSrc component shows only one row under the Connection Managers tab:
The datareadersrc component editor displays the warning message: "Not all connection managers have been set. Set all connection managers.". Clicking the Refresh button causes the error message to be displayed "The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."
I am prevented from assigning my Connection Manager object the DataReaderSrc.
The package already contains one Connect Manager object:

If I use the example from SQL Server BOL (http://msdn2.microsoft.com/en-us/library/ms135917.aspx), and make a new package for the sample in the same project, the sample works. The only thing that I can see that is significantly different between my code and the sample is that my DataReaderDestination has a lot more data in it, but here's the relevant code:
string dtexecArgs;
string dataReaderName;
DtsConnection dtsConnection;
DtsCommand dtsCommand; //IDbCommand
IDataReader dtsDataReader;
DataTable dtsTable;
dtexecArgs = @"/FILE ""C:Documents and Settings heinMy DocumentsVisual Studio 2005ProjectsCA3DataImportToolML3000_IntegrationProjectPackage.dtsx"" ";
dataReaderName = "DataReaderDest";
dtsConnection = new DtsConnection();
dtsConnection.ConnectionString = dtexecArgs;
dtsConnection.Open();
dtsCommand = new DtsCommand(dtsConnection);
dtsCommand.CommandText = dataReaderName;
dtsDataReader = dtsCommand.ExecuteReader(CommandBehavior.Default); // EXCEPTION HERE
I have created an SSIS On my PC, That extracts data out of Lotusnotes. When I run it manaully from Visual studion-execute package, it works just fine. However, when I go tO Management studio, chose the servername, then go to Stored Package-MSDB- And chose Packagename, and hit Run PKG from there, it gives me the error below. Server has 2005 AND IS WINDOWS 2003 OS.
The product level is insufficient for component "datareader source"
Can you tell me why the same pkg will work fine when executed from Visual studio-But when I go the run it from Storedpackages-MSDB-it fails.
how SQL 2012 would treat a literal string for a comparison similar to below. I want to ensure that the server isn't implicitly converting the value as it runs the SQL, so I'd rather change the data type in one of my tables, as unicode isn't required.
Declare @T Table (S varchar(2)) Declare @S nvarchar(255) Insert into @T Values ('AR'), ('AT'), ('AW') Set @S = 'Auto Repairs' Select * from @T T where case @S when 'Auto Repairs' then 'AR' when 'Auto Target' then 'AT' when 'Auto Wash' then 'AW' end = T.STo summarise
in the above would AR, AT and AW in the case statement be treated as a nvarchar, as that's the field the case is wrapped around, or would it be treated as a varchar, as that's what I'm comparing it to.
I am loading/executing packages from c# and I need to populate a temp table from user input and pass this table as a variable to the datareader source components sql command. I am using expression to build this query, but I am getting design time error when I have this command..
"select id, (SysDate + 28) as ExpiresDate from Table1 where id in (Select Id from" +@[User::Table2]+")"..
I have declared Table2 as a variable of type Object and I am creating Table2 in C# and I am assigning that Table to the user Table. But in the design mode, I am getting an error...expression cannot be evaluated.
I'm using sys.dm_fts_parser dynamic management function to tokenize a string of characters >4000. The function doesn't accept a query_string parameter >4000 characters. Is there a way around this? I've tried to execute the SELECT defined in the function but that doesn't work.
Hello, I have 2 table, "table1" is the source one and the other one "table2" is the destination. Columns in Table1 and in Table2 are nvarchar(max). Data loaded from table1 is performed by SSIS OLEDB data flow source, I have found out that opening "Data flow Path Editor" in the Metadata, columns are as: DT_WSTR with lenght 4000.
First question: Why SSIS limit the column to 4000.
Then I get some error for this issue, with the error: input column "col1" (xxxx) and reference column named (coln) have incompatible data type.
As written before both columns are string, the problem is that SSIS limit the lenght of the string to 4000.

Changing the cmd.Parameters as follows works:

Is there a way to evaluate an expression (like the derived column component) in a custom component? If so where should I look first? Is there an example?
An extremely simple sample is to put in an expression and evaluate one column and then add that to another column to create a new column. i.e. newcolumn = column1 + column2.
I realize that the derived column allows me to do this but I'm trying to figure out if it is possible to do this in a custom component without having to build my own expression evaluator.
I am reading an excel file with a field that consists of lastname, firstname. I am using the Derived Column transformation to separate the two fields. The firstname expression works fine: SUBSTRING(F1,FINDSTRING(F1,",",1) + 1,LEN(F1) - FINDSTRING(F1,",",1))
However, the lastname field keeps giving me an error when I use SUBSTRING(F1,1,FINDSTRING(F1,",",1) - 1). I'm sure I've used this substring before in visual studio. Could this be a bug? The error is below.
[Add Columns [2886]] Error: The "component "Add Columns" (2886)" failed because error code 0xC0049067 occurred, and the error row disposition on "output column "LastName" (3100)" specifies failure on error. An error occurred on the specified object of the specified component.
When I enter over 4000 chars in any ntext field in my SQL Server 2005 database (directly in the database and through the application) I get an error saying that the data could not be updated because string or binary data would be truncated.Has anyone ever seen this? I cannot figure out what is causing it, ntext should be able to hold a lot more data that this...
I have implemented a custom source component that can be used as the data source in the Data Flow task.
I have also created a custom UI for this component by using the IDtsComponentUI .
But my component does not have the capability of setting the custom properties via the DTS Variables using the Expression Builder.
I have looked around for samples on how to do this, but I can only find samples of how to do this for custom Control Tasks, i.e. IDtsTaskUI.
My question is, How can implement the Expression Builder in my custom Source component + custom Source UI. Or do you know of any samples which I can look at.
I have a table which has expression as a column and the data looks similar to the following .
ID (int) Expression (nvarchar data type)
1 8*(1/2)-6
2 278*(1/4)-2
3 81*(3/5) +4
I now have the expression as an nvarchar. (Ex: 8*(1/2)-6)
Now I need to evaluate this expression and output the result (which is -2 in above Ex) .Can someone give me idea on how do I evaluate the expression which is available as a string. I need to write a procedure for this.
I am unable to cast/convert nvarchar to float/int
Any sample code would be greatly appreciated.
This a very urgent requirement for me.Please get back
I can't figure this one out. I don't have enough knowledge of the string functions I guess.
I need to pull a value out of a variable I setup in a for each loop. The value is the filename/path of each source file being processed. Let's say the variable that has the source file path is called VAR1.
One sort of off topic thing I've noticed is when watch the variable in bebug mode and I look at the value of VAR1 it has double back slashes. Here's an example of the value of VAR1:
"\\L3KRZR6.na.xerox.net\C$\Documents and Settings\ca051731\Desktop\Project4\DPT_20070926.ver"
How come the back slashes have been doubled? And do I need to account for that when I start parsing the string value?
Anyway, I need to grab part of the filename from VAR1 and I need the value populated at the start of the for each loop container - ideally when I capture VAR1 in the for each container. I'll be using the string in drop table, create table and create index statements before the actual Data Flow task within the overall package
In the above example I need to grab the characters before the underscore and after the last \. So I'd need the string "DPT" captured in this example.
The actual string could be 1 to 3 characters long, even though this example has it as 3 long.
Underscores could exist anywhere in the actual UNC path once this package is moved to our actual system environments so I can't key off of the underscore.
Because I can't count on the string being a fixed lenght I can't just use a positional string function and grab specific text starting/ending at specific points.
Is there a way to use the various string functions in the expression builder to grab the text between the right most underscore and the right most back slashes or something like that? Ideally I'd like to setup a new expression based packed scope variable called VAR2 and build it using string functions applied to VAR1.
I'm not exactly sure how to phrase this problem. If I'm going about this the wrong way, any pointers would be appreciated.
I am using an expression for a data source connection so I can decide which server/database to use at runtime. I also need to pass credentials to use for that connection. The only way I'm able to get this to work is to specify "No Credentials" for the data source and then pass a DataSourceCredentials to the report throught the report viewer. This works, for the most part, but puts a "Change Credentials" link in the report viewer.
What I think would be much better is if I could specify the credentials in the connection string that I pass. However, everything I've tried so far has not worked. I get errors complaining that the compination of options is invalid or that the report server cannot find the credentials of "unknown keyword: User Name". All by trying various combinations of things.
How do other people go about this? I've seen blogs implying that this is not such a big deal (that credentials CAN be passed over in the connection string). Hopefully I'm missing something simple here. If I have no choice, the "Change Credentials" link will not be the end of the world, but that's very sloppy. The people viewing this report will not know anything about the database credentials and I'd rather not show them somthing as inviting as a link that can get them off track.
I have what should be a simple string formatting issue -- removing all alpha characters from a phone number. T-SQL below is simple and works just fine:
declare @home_phone as char(14); set @home_phone = '(123)979-3206'; set @home_phone = REPLACE(@home_phone,'-',''); set @home_phone = REPLACE(@home_phone,'(',''); set @home_phone = REPLACE(@home_phone,')','');
The condensed version below works equally well:
set @home_phone = REPLACE((REPLACE((REPLACE(@home_phone,'(','')),')','')),'-','');
Either script above returns correct result:
select @home_phone; Result = '1239793206'
HOWEVER, within SSIS Derived Column expressions, this function fails to remove parentheses. First of all, Expression Builder doesn't like outer single quotes (turns red) which I resolved by using double quotes resulting in the following expression:
Unfortunately, this expression fails to remove parentheses and instead returns: '(123)9793206'
I've tried several different permutations--no inner single quotes; adding more inner single quotes; etc., but so far no success. Any suggestions would be much appreciated!
How would I convert an expression like on of these to all upper case first letters with remaining letters lower case? VB has a function for that but sql doesn't seem to. I thought about having a loop go through each character to check for spaces. I've written a couple of similar pieces of code in VB when a while ago, but is there a better way? Thanks :)
Just a couple of typical examples of how the data should appear ~
