SSIS Ntext Update

Oct 15, 2006

A sql server 2000 table contains a ntext field that needs to be updated. The update is replacing a particular string in the ntext field. I heard it's hard to do it in sql server 2000 itself. Can it be done easily in an SSIS? Please kindly provide example. Thanks.

Any ideas? thanks...

Hi All,

I will be doing stress test for my app.

Loading thousands of records to the DB through bulk insert.
There's one field NText which I have left NULL because it will be hard to gen dummy flat file to it.

I have another table which has the Ntext Value which i will want to copy and duplicate to the other table.

what is the way to do it?

simply said i want to update a record with NULL value from one table with NText field with the value from another table..

Data Truncation Does Not Trigger Truncation Error - Why?

Jun 27, 2007

Hi,



I have a data file that has numeric data that looks like:



1.123456



And this column is defined as a DT_NUMERIC(18.6) in the flat file conn mgr.



As an experiment, I changed the destination column to a NUMERIC(18,0) - hoping that this would throw a truncation error at the flat file task level (where I have Truncation on all columns set to "fail component").



Not a peep. It loaded the data into the table, chopping off the 6 digits after the decimal point.



You would THINK that this would cause an error, but no. Why is this? The flat file task complains about all kinds of things, but this is such a gross error, you would think it would catch it!



Thanks

Use Replace() In An Update In A Large Ntext

Apr 21, 2008

I've got a table that I have to update in preparation for our environment move (2k to 2005 SP2). The developers that designed the application created a table called schemas, which holds the contents of an XML file inside of an ntext field named Data.I need to parse through the field and do a find/replace to replace all instances of www.site.com with www7.site.com. It's all over the place in the file. The problem is, that the datalength() of each of the fields (there are 2 rows) are above 15000.normally, I'd run something like this:update schemas set data=replace (cast(Data as varchar(max)),'www.site.com','www7.site.com') where data like '%www.site.com%'Smaller columns it works great - but it won't work on these because they're too big (the update will chop anything beyond the varchar(max) value). I could do it manually, but this DB will be refreshed from production on a weekly basis and I'd like to script as many of the environment changes to the DB as much as possible. Any ideas?

Ntext And Update/insert Triggers

Jul 23, 2005

SQL Server 2000 : I have a series of tables which all have the samestructure. When any of these tables are modified I need to syncrhoniseall of those modifications with one other table wich is a sort of mergeof the individual tables with one extra column.For most of these tables this is not a problem. The problem arriveswhen one of the tables has an ntext column which obviously can not beused in an update or insert trigger.Here's an example of one of them:CREATE TABLE tblImages(ID INT IDENTITY(1,1) PRIMARY KEY,Inventory nvarchar(8) NOT NULL,Coll nvarchar(8) NOT NULL,ImageFile nvarchar(128) NOT NULL,ImageNotes ntext NULL,TS timestamp NULLCONSTRAINT U_Images UNIQUE NONCLUSTERED (ItemCode, Inventory, Coll,ImageFile)I then had created an update trigger which looked like this:CREATE TRIGGER COLLNAME_UTRIGGER ON COLLNAME_ImagesFOR UPDATEASBEGINUPDATE tblImages SETInventory = inserted.Inventory,Coll = 'COLLNAME',ImageFile = inserted.ImageFileName,FROM inserted INNER JOIN tblImages ON inserted.ItemCode =tblImages.ItemCode ANDinserted.Invventory = tblImages.Invventory AND tblImages.Coll ='COLLNAME' ANDinserted.ImageFileName = tblImages.ImageFileUPDATE tblImagesSET ImageNotes=inserted.NotesFROM inserted INNER JOIN tblImages ON inserted.ItemCode =tblImages.ItemCode ANDinserted.Inventory= tblImages.Inventory AND tblImages.Coll ='COLLNAME' ANDinserted.ImageFileName = tblImages.ImageFileEND " & vbCrLf)The first update in my trigger, be it an update or insert trigger,works fine. It crashes with the "Cannot use text, ntext or imagecolumns in the 'inserted' or 'deleted' tables." error in the secondpart.I have read various messages through the Internet on this and severalof them reference using INSTEAD OF triggers and views. I have neverused those before as this is my first work with SQL 2000. None of theexamples of INSTEAD OF triggers I have seen yet use the actual insertedtables and I haven't quite understood how to use them correctly.Can someone help me with the basic syntax as this trigger is one ofseveral that I am going to have to get working.Thank you in advance for any help, assistance, suggestions or"direction pointing" you may provide.

Function That Replaces Ntext And Compares Ntext With Nvarchar

Nov 28, 2007

I am running this query to an sql server 2000 database from my aspcode:"select * from MyTable whereMySqlServerRemoveStressFunction(MyNtextColumn) = '" &MyAdoRemoveStressFunction(MyString) & "'"The problem is that the replace function doesn't work with the ntextdatatype (so as to replace the stresses with an empty string). I hadto implement the MySqlServerRemoveStressFunction, i.e. a function thattakes a column name as a parameter and returns the text contained inthis column having replaced some letters of the text (the letters withstress). Unfortunately, I could not do that because user-definedfunctions cannot return a value of ntext.So I have the following idea:"select * from MyTable whereCheckIfTheyAreEqualIngoringTheStesses(MyNtextColum n, '" & MyString &"')"How can I implement the CheckIfTheyAreEqualIngoringTheStessesfunction? (I don't know how to combine these functions to do what Iwant: TEXTPTR, UPDATETEXT, WRITETEXT, READTEXT)

If you are running in Full Recovery Mode and do a full backup every night but never do a backup of the log during the day does the log file ever truncate?

Truncation Error

Aug 30, 2007

Hello Everyone and thanks for your help in advance.  I am working on importing a flat text file into SQL Server 2005 and am having problems.  The flat file is a CSV text file with " being used as a text qualifier.  Each line is broken by a CrLf combination.  When I try importing this file into a SQL Server 2000 table using the same datatypes and sizes for each column, it works perfectly fine with the data importing as expected.  However, in SQL Server 2005, again using the identical column datatypes and sizes, the import fails giving me warnings such as:
 * Warning 0x802092a7: Data Flow Task: Truncation may occur due to inserting data from data flow column "Column 0" with a length of 50 to database column "MLS_ID" with a length of 10.  (SQL Server Import and Export Wizard) 
Virtually every columns gives this type of warning, yet I don't understand why since the columns are all variable in length (every message says a column length of 50) and all are delimited rather than fixed size.  Then later in the import, errors occur something like:
 * Error 0xc02020a1: Data Flow Task: Data conversion failed. The data conversion for column "Column 15" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".  (SQL Server Import and Export Wizard)  * Error 0xc020902a: Data Flow Task: The "output column "Column 15" (70)" failed because truncation occurred, and the truncation row disposition on "output column "Column 15" (70)" specifies failure on truncation. A truncation error occurred on the specified object of the specified component.  (SQL Server Import and Export Wizard)
I haven't got a clue as to why this is happening.  For the record, on the flat file source screen, I have ensured that delimited has been selected rather than fixed width.  Any help on this issue owuld be greatly appreciated.  Thanks.

Varchar Truncation

Jan 26, 2007

Hello,I am attempting to write a stored procedure that builds and executes adynamic SQL statement which can be up to 8000 characters long.Therefore, I have declared a variable of type varchar(8000) which,according to the documentation, is the maximum acceptable length ofsuch a variable. Unfortunately, however, SQL Server seems allowvarchars to only be half this size: the resulting string keepingsgetting truncated to 4000 characters as reported by the len function.Is there setting somewhere that would fix this behavior or somework-around that I can employ that would allow me to execute a dynamicsql statement that is longer than 4000 characters?(note: I am not using the sp_executesql proc as it maxes out at 4000; Iam simply calling EXEC which, according to the docs, should be fine)Thank You.

Truncation Errors

Jun 15, 2007

We use SQL Server 2005 x64 Enterprise and I have created a SSIS routine to replace a legacy DTS routine that reads from a Data Reader Source and writes to a SQL Server 2005 database. The field I am receiving the truncation error on is "Description" and it is set as nvarchar(50), which it always has been, and the old DTS routine works fine on it. I checked the contents of description and the maximum number of characters in any row is 28. I have tried changing it to nvarchar(max), nvarchar(4000) and ntext but it still fails with a truncation error. Any leads on how I may solve this issue?

Truncation Error

Jan 3, 2008

All,

I am having a strange problem that I have been looking at for a day now, and my head is straing to hurt as I have banged my head on the desk so many times. I have written an extensible set of classes that allow me to build SSIS packages dynamically via a web front end. I am finding this code is working OK, but I have this silly bug.

The code is trying to generate an SSIS package that does somethign very simple, and transfer data from a 10 coumn table with a mix of data types, move through another component that adds a couple of extra columns on basic on some variables, then map it onto a OLD DB destination. This code works fine, until I start using strings of various lengths.

When the package runs, it fails validation with errors saying that truncation may occur as I am trying to put a 100 character string, into a 50 character string. The error is logical as you wouldn';t want to do that, but this is not what I am doing. I am actually transfering data from a 50 character string into a 100 character string. When I try it with a table where the strings are the same length at both ends, or no strings are involved, everything works fine, and the data goes from the source to the destination.

I must be setting something slightly wrong which only triggers this problem when the sizes don't match, but the data flow direction is fine, and the data types match. I have included the code from the piece of code that 'writes' the output part of the package. If anyone has any idea what might be going wrong, I would be forever in their debt!




Code Block
private void ConfigureInputColumns(Package package, MainPipe pipe, IDTSOutput90 SourceColumnCollection)
{
_InstanceOfDestination.AcquireConnections(null);
_InstanceOfDestination.ReinitializeMetaData();
IDTSPath90 path = pipe.PathCollection.New();
path.AttachPathAndPropagateNotifications(SourceColumnCollection,_Destination.InputCollection[0]);

IDTSInput90 input = _Destination.InputCollection[0];
IDTSVirtualInput90 vInput = input.GetVirtualInput();
int iIndex = 0;
foreach (IDTSVirtualInputColumn90 vColumn in vInput.VirtualInputColumnCollection)
{
// Call the SetUsageType method of the destination
// to add each available virtual input column as an input column.
_InstanceOfDestination.SetUsageType(input.ID, vInput, vColumn.LineageID, DTSUsageType.UT_READWRITE);
}
IDTSExternalMetadataColumn90 exInputColumn;
foreach (IDTSInputColumn90 inColumn in _Destination.InputCollection[0].InputColumnCollection)
{
// create the MAP
// What we need to do here, is say what source column, goes to what destination column.
// we read by index, and we need to map the specifics, we could control just 3 of 20 columns
// to whatever column we wanted in the destination......
// We know the name of the inColumn - It is called inColumn.Name, we need to find the column
// we want to map with by finding its name.
if (inColumn.Name == "BatchID" || inColumn.Name == "ValidationStatus")
{
exInputColumn = _Destination.InputCollection[0].ExternalMetadataColumnCollection[inColumn.Name];
// map it
_InstanceOfDestination.MapInputColumn(_Destination.InputCollection[0].ID, inColumn.ID, exInputColumn.ID);
}
else if (Mapping.Map.ContainsKey(inColumn.Name))
{
exInputColumn = _Destination.InputCollection[0].ExternalMetadataColumnCollection[Mapping.Map[inColumn.Name]]; // inColumn.Name

// map it
_InstanceOfDestination.MapInputColumn(_Destination.InputCollection[0].ID, inColumn.ID, exInputColumn.ID);
}
}
_InstanceOfDestination.ReleaseConnections();

Transaction Log Truncation

Sep 6, 2007



I have always assumed that when you backup a SQL Server database the transaction log is automatically truncated so that there is no need to explictly truncate it. It makes sense to me, you would not normally need logs from before the most recent backup. BOL, with all its talk about check points etc, seems to hint at this but I can't find an explicit statement to this effect.

Anyone?

Truncation Warning

May 24, 2007

Hello,



I'm having a problem with one of my packages due to a truncation warning that I can't get rid of. It's not the end of the world, because the package still works. It's just extremely frustrating.



The problem arises in a derived column item in a data flow task. There is a postcode field in the data flow which has space for 20 characters. I create a derived column from this which simply removes any spaces:



Derived Column Name: Postcode

Derived Column: Replace 'Postcode'

Expression: REPLACE(" ",Postcode,"")

Data Type: string [DT_STR]

Length: 20

Code Page: 1252 (ANSI - Latin I)



However when I use this expression, or anything else which uses the replace function, I end up with the warning message:



Warning 1 Validation warning. Create Staging Tables: Derived Column [20555]: The result string for expression "REPLACE(" ",Postcode,"")" may be truncated if it exceeds the maximum length of 4000 characters. The expression could have a result value that exceeds the maximum size of a DT_WSTR.



I have tried everything I can think of to get rid of the warning. Is there some way I can use the replace function, but not have the system convinced that I'm about to go over the maximum size limit?



Many thanks

Backup, Truncation, Behavior

Mar 22, 2005

Scenario:
I have a database in SQL Server 2000 with 90gb of data. It is growing every day with a some millions records. In order to get superior performance I rebuild the indexes every night. The job takes about 1.5 hours, and sometimes causes to the log file to grow to 30-40 gigs. I do a backup of the log files every 20 minutes, and this causes an log truncation to happen automatically (according to the MS documention).
Problem:
The log files makes the disk goes full. I cannot insert new disks at this point.
Question:
When rebuilding the indexes takes 1.5 hours, and I do a log backup (which also does a truncation) every 20 minutes, will the log backup ever get to do something with the transaction log while its still working on a transaction (doing the rebuild of index)?
Observation:
It seems like the 20 minute log backup is of no help because I see the log files grows so big.
