I am saving large text document in an image type of column in a SQL Server 2000 table. How will I set up searching of words/ phrases for data stored in this column?
Hi,This is driving me nuts, I have a table that stores notes regarding anoperation in an IMAGE data type field in MS SQL Server 2000.I can read and write no problem using Access using the StrConv function andI can Update the field correctly in T-SQL using:DECLARE @ptrval varbinary(16)SELECT @ptrval = TEXTPTR(BITS_data)FROM mytable_BINARY WHERE ID = 'RB215'WRITETEXT OPERATION_BINARY.BITS @ptrval 'My notes for this operation'However, I just can not seem to be able to convert back to text theinformation once it is stored using T-SQL.My selects keep returning bin data.How to do this! Thanks for your help.SD
The ERP manufacturer used an image data type to store large text data fields. I am trying to move these data types from one database to another database using either Sql Queries or MS Access. I can cast them as an 8000 char varchar to read them directly but have no luck importing into these image data fields.
Access and Crystal are not able to read these fields directly.
Any suggestions? Most information about these fields has to do with loading files but I am just moving data.
I am reading the WROX "Professional SQL Server 7 Programming" book. The following code appears on page 424:
CREATE TRIGGER ProductIsRationed ON Products FOR UPDATE AS IF EXISTS ( SELECT 'True' FROM Inserted i JOIN Deleted d ON i.ProductID = d.ProductID WHERE (d.UnitsInStock - i.UnitsInStock) > d.UnitsInStock / 2 AND d.UnitsInStock - i.UnitsInStock > 0 ) BEGIN RAISERROR('Cannot reduce stock by more than 50%% at once.',16,1) ROLLBACK TRAN END
The trigger fires when an UPDATE is made to Products table. The author states that the Inserted and Deleted tables only exist for the life of the trigger, not before, and not after the trigger runs. If this is true, then why would there be any rows in the Deleted table in this case? No rows were deleted within the trigger. As far as I can see, no rows have been updated either. If the condition does exist, no rows will be updated, and an error will be displayed. Otherwise, the row will be updated. Then there would be a row in the inserted table. But then the trigger is finished and the inserted table for that trigger disappears. I think my logic is flawed, which is why I am writing. I don't think I fully understand the Inserted and Deleted tables.
I want to know how inserted and deleted temp tables in SQL server work. My question is more regarding how they work when multiple users accessing the same database. Suppose two users update the database at the same time. In that case what are the values stored in the inserted and deleted tables.
I have a trigger that records changes to the database as in an audit trail. Like any other audit trail I insert data into my audit table from the inserted and deleted temp tables in MS SQL Server. I however am not clear as to how these inserted and deleted tables store values when two users update the database at the same time. Are there separate inserted and deleted tables for each session. The users access the database thru ASP pages.
The audit trail I am trying to use is http://www.nigelrivett.net/AuditTrailTrigger.html
I actually would like to store the inserted and deleted temp tables into other temporary tables so that I can access these tables thru a stored procedure. This is when the problem of same users updating the temporary tables is more pronounced.
I just ran across an issue on a SQL 2000 sp4 db where RI was being maintained solely with triggers. I am attempting to change the primary key of a parent table and cascade the results to all its children without using the vendor-supplied trigger code (long story...) using an INSTEAD OF trigger.
My question is: does SQL Server create any kind of relationship between the inserted and deleted tables that I could exploit since the key field is unavailable?
I am trying to avoid having to add a surrogate key to each of the children just for this activity (as there are many M rows in each and no other suitable unique column combinations that span all the child tables).
I have a stored procedure that's running a little slower than I would like. I've executed the stored proc in QA and looked at the execution plan and it looks like the problem is in a trigger on one of the updated tables. The update on this table is affecting one row (I've specified the entire unique primary key, so I know this to be the case). Within my trigger there is some code to save an audit trail of the data. One of these statements does an update of the history table based on the inserted and deleted tables. For some reason this is taking 11.89% of the batch cost (MUCH more than any other statement) and within this statement 50% of the cost is for a table scan on inserted and 50% is for a table scan on deleted. These pseudo-tables should only contain one record each though.
Any ideas why this would be causing such a problem? I've included a simplified version of the update below. The "or" statements actually continue for all columns in the table. The same trigger template is used for all tables in the database and none of the others seem to exhibit this behavior as far as I can tell.
Thanks for any help! -Tom.
UPDATE H_MyTable SET HIST_END_DT = @tran_date FROM H_MyTable his INNER JOIN deleted del ON (his.PrimaryKey1 = del.PrimaryKey1) and (his.PrimaryKey2 = del.PrimaryKey2) INNER JOIN inserted ins ON (his.PrimaryKey1 = ins.PrimaryKey1) and (his.PrimaryKey2 = ins.PrimaryKey2) WHERE (his.HIST_END_DT is null) and ((IsNull(del.PrimaryKey1, -918273645) <> IsNull(ins.PrimaryKey1, -918273645)) or (IsNull(del.PrimaryKey2, -918273645) <> IsNull(ins.PrimaryKey2, -918273645)) or (IsNull(del.Column3, -918273645) <> IsNull(ins.Column3, -918273645)))
I want to compare the before and after values of an UPDATEd column using a trigger. I want to know if the value in the column has changed. Simple? No!
As you know, SqlServer puts the before image of the UPDATEd rows into the DELETED virtual table and the after image of the UPDATEd rows in the INSERTED virtual table.
So you would get the before and after data by doing a SELECT on these tables. But here is the problem - how do you join the tables? What if there are >1 rows in these 2 tables (because the UPDATE affected >1 rows) - how do i know which "old"/DELETED rows correspond to which "new"/INSERTED?" Ok - I could join the 2 tables on the primary key, but what if the primary key was updated? In that case the join would not work - the DELETED table would contain the old primary key value and the INSERTED table would contain the new (different) primary key value. In fact, ALL of the columns may have been changed by the UPDATE.
Now, there is another thing to try with triggers - the IF UPDATE ( <columname> ) test. This is designed to tell you if a specified column was UPDATEd by the last UPDATE. However, this will return TRUE for any UPDATE that mentions the column - even if the UPDATE does not change any data! So I cannot determine whether a certain column has had its value changed with this either.
So then you can try another test mentioned in the docs for CREATE TRIGGER - the IF COLUMNS_UPDATED() test. However, this will report that a column has been updated, NOT whether the data has changed as aresult of that UPDATE. So if you UPDATE the value in the column to the same value as it was beforehand (admittedly, a pointless thing to do, but it could happen in some apps), this fuction will say, yes, this column was updated.
So my question remains - how do I know if the data has changed in a column after an UPDATE, using a trigger? Any ideas?
I dont know what I am doing wrong. The trigger (see below) is doing what I want it to do when I do this:
INSERT INTO dbo.personal
(personal_id, chef_id,fornamn, efternamn)
VALUES
(40, 100, 'Malin', 'Markusson' , 'Boss')
but when I remove one value, the result in the logtable is NULL:
INSERT INTO dbo.personal (personal_id, chef_id,fornamn, efternamn)
VALUES
(40, 100, 'Malin', 'Markusson' )
How can I change the trigger so that it will give me the information of the values that have been updated, inserted or deleted when I dontchange all values (just a couple of them)?
My trigger: CREATE Trigger trigex
ON dbo.personal
FOR insert, update,delete
AS
INSERT INTO logtable (Innan_värde, Ny_värde)
SELECT
rtrim(cast(d.personal_id as varchar)+', '+cast(d.chef_id as varchar)+', '+rtrim(d.efternamn)+', '+ rtrim(d.fornamn)+ ', '+ rtrim(d.titel)),
(cast(i.personal_id as varchar)+', '+cast(i.chef_id as varchar)+', '+rtrim(i.efternamn)+', '+ rtrim(i.fornamn)+ ' '+ rtrim(i.titel))
FROM inserted i full join deleted d on i.personal_id = d.personal_id
I have two SQL 2005 SP2 Server and want to use the transaction replication with updateable subscriber. Now the problem is that i can do any changes on the master server. But if i want to change a record on the subscriber which contains a ntext, text, oder image column - then i geht the error that the field will be NULL on the master.
Is there any solution to fix this problem? I dont wan`t to change the datatype vom ntext to varchar(max) !!
We have an app that uses triggers for auditing. Is there a way to know the order that the records were inserted or deleted? Or maybe a clearer question is.... Can the trigger figure out if it was invoked for a transaction that "inserted and then deleted" a record versus "deleted and then inserted" a record? The order of these is important to our auding.
I have a table that sometimes has modifications to column(s) comprising the primary key [usually "end_date"]. I need to audit changes on this table, and naturally, turned to after triggers.
The problem is that for updates, when the primary key composition changes, I'm not able to relate/join using the primary key - obviously, it no longer matches across INSERTED and DELETED. Now, for a single row update, it's easy to check for updates on PK columns and then deduce what changes were made...
So the real question is: are rows in INSERTED and DELETED always in matching order (1st row in INSERTED corresponds to the 1st row in DELETED...)?
I don't want to put a surrogate key (GUID nor IDENTITY) on the base table if at all possible. INSERT... SELECT from the inserted/deleted tables into a temp table with identity column is fine, and is what I'm currently doing; I would like MVP or product engineer level confirmation that my ordering assumption is correct.
Testing using an identity surrogate key on base table, and selecting from the Ins/del tables, and the temp tables without an order by clause seems to always return in proper order (proper for my purposes). I've tested under SQL 2005 RTM, SP1, SP2, and SP2 "3152".
FYI, I've lost the debate that such auditing is better handled by the application, not the database server...
Aside: why doesn't the ROW_NUMBER() function allow an empty OVER( ORDER BY() ) clause? Will SQL ever expose an internal row_id, at least in the pseudo tables, so we can work around this situation?
SQL ERROR - I need DISTINCT but can use it with image,ntext, text - How To work around??? ! more - How to Work around - MIN() I cant use it when having text in SELECT statement The text, ntext, or image data type cannot be selected as DISTINCT.

I do not understand the error message but I do know it is associated with a specific table and one of its indexes. If I try to drop the index that is the error message I get.
I have copied the data from the table to a new table and rebuilt the indexes on the new table and everything is working fine.
The bad table is now renamed to myTable_BAD. I now want to delete it but can't as everytime I enter drop table myTable_BAD
I get Page (1:404399), slot 5 for text, ntext, or image node does not exist.
I would like to wrap the following code in a function and reuse it. Â I use this code in many triggers.
DECLARE @Action as char(1); SET @Action = (CASE WHEN EXISTS(SELECT * FROM INSERTED) AND EXISTS(SELECT * FROM DELETED) THEN 'U' Â -- Set Action to Updated. WHEN EXISTS(SELECT * FROM INSERTED) THEN 'I' Â -- Set Action to Insert. WHEN EXISTS(SELECT * FROM DELETED) THEN 'D' Â -- Set Action to Deleted. ELSE NULL -- Skip. It may have been a "failed delete". Â Â END)
Is it possible to write a function and pass the INSERTED and DELETED logical tables to it?
Hi,I have a problem to insert(update) a long text (more than 64K) intoSQL 2000 (datatype - 'text'). It cuts the data and insert only 64K.MSDN says: "When the ntext, text, and image data values get larger,however, they must be handled on a block-by-block basis. BothTransact-SQL and the database APIs contain functions that allow applications towork with ntext, text, and image data block by block." Could somebodygive me an example how to do this, please.Thank you

Hello, When I am using DISTINCT in the SELECT clause for a table having a column of datatype "ntext" in SQL 2000 as well SQL 2005, it fails giving the error as "ntext data type cannot be selected as DISTINCT". This is coz "The text, ntext, or image data type cannot be selected as DISTINCT."
But I am able to insert into a temporary table having a column whose datatype is nvarchar) using this SELECT clause in SQL 2000. Please advice me how this happens. If I am not worng, implicit conversion has happened. But this insert fails raising the same error in SQL 2005. Please help me to find the difference thanks in advance!
My organization have a web-based application and needs it to support multilingual so we will be adapting our app to use unicode. However, one of our problems is to convert existing data from text to ntext. I couldn't find anything that document this. What is the best way to do that? I would like to be able to migrate the data from an existing text column to another ntext column in the table.
If I can't do that, what are the options? If it's possible, I would like to be able to do this in sql script.

Hello Guys,Have been getting this error( Implicit conversion from data type ntext to varchar is not allowed. Use the CONVERT function to run this query. ) when running on the live environment but it was fine when run locally. If anyone has similar problem please let me know the fix you have done. Thank you.
I have to run a dynamic sql that i save in the database as a TEXT data type(due to a large size of the sql.) from a .NET app. Now i have to run this sql from the stored proc that returns the results back to .net app. I am running this dynamic sql with sp_executesql like this.. EXEC sp_executesql @Statement,N'@param1 varchar(3),@param2 varchar(1)',@param1,@param2,GO As i can't declare text,ntext etc variables in T-Sql(stored proc), so i am using this method in pulling the text type field "Statement". DECLARE @Statement varbinary(16)SELECT @Statement = TEXTPTR(Statement)FROM table1 READTEXT table1.statement @Statement 0 16566 So far so good, the issue is how to convert @Statment varbinary to nText to get it passed in sp_executesql. Note:- i can't use Exec to run the dynamic sql becuase i need to pass the params from the .net app and Exec proc doesn't take param from the stored proc from where it is called. I would appreciate if any body respond to this.

I brief you about my system, I used List manager system to store the messages and distribute to all members. Right now,by design the Lyris system keep the message in the text field which mean it 's not support multilanguage directly because of unicode field. We needs to create new Db which has the data structure as same as Lyris but just one difference is keep the message in unicode format (ntext) which we need the sql script to automatically update the new record get from Lyris to new DB.
If I can't do that, what are the options? If it's possible, I would like to be able to do this in sql script.
