I've got a table that gets updated with live-data constantly throughout the day. I've got to run some statistical analysis on the data in this table based off of the value of one of the columns. The column can be 4 values, but I'm only looking to analyze data for rows containing one of two of the 4 total values. IE
Table
|Status| more data....|
|1|......|
|2|......|
|3|......|
|4|......|
|1|......|
|4|......|
I want to only analyze the data of rows with 1 and 4 as values. I don't care about 2 or 3...
I was thinking of using a Trigger, but I'm not aware of a way to analyze the data that fires the Trigger.
Ideally, I'd like to do something like
CREATE TRIGGER analyze ON table AFTER INSERT WHERE column = '1' OR column = '4' AS 'Trigger sql here'
Is this possible?
Not sure if this is the right forum to post this question to, so if it's not, please accept my apologies.
I'm working in SQL Server 2005 with a database that was migrated to 2005 from SQL Server 2000. I have to alter a trigger on a table for some functionality changes, and when I modify the trigger and then access it through the application the database is working with, I receive this error:
There was a error in the [stored procedure name] procedure. Error Number: -2147217900 Error Description: [Microsoft][ODBC SQL Server Driver][SQL Server]The definition of object '[trigger name]' has changed since it was compiled.
[stored procedure name] and [trigger name] are where the actual names appear in the message.
I've tried running sp_recompile on the trigger, stored procedure, and table that are associated with this, and nothing works. I have dropped the trigger, which allows the save process to complete (but doesn't perform the required functionality, of course), and then re-created the trigger, but the error message still comes up. The compatibility level for the database is SQL Server 2000 (80) (as it was migrated from SQL Server 2000 as I mentioned above).
Has anyone seen this, and if so, how can I fix it?
This problem is being seen on SQL 2005 SP2 + cumulative update 4
I am currently successfully using the output clause of an insert statement to return the identity values for inserted rows into a table variable
I now need to add an "instead of insert" trigger to the table that is the subject of the insert.
As soon as I add the "instead of insert" trigger, the output clause on the insert statement does not return any data - although the insert completes successfully. As a result I am not able to obtain the identities of the inserted rows
Note that @@identity would return the correct value in the test repro below - but this is not a viable option as the table in question will be merge replicated and @@identity will return the identity value of a replication metadata table rather than the identity of the row inserted into my_table
Note also that in the test repro, the "instead of insert" trigger actually does nothing apart from the default insert, but the real world trigger has additional code.
To run the repro below - select each of the sections below in turn and execute them 1) Create the table 2) Create the trigger 3) Do the insert - note that table variable contains a row with column value zero - it should contain the @@identity value 4) Drop the trigger 5) Re-run the insert from 3) - note that table variable is now correctly populated with the @@identity value in the row
I need the behaviour to be correct when the trigger is present
GO /************************************************ 2) - Create the trigger ************************************************/ CREATE TRIGGER [dbo].[trig_my_table__instead_insert] ON [dbo].[my_table] INSTEAD OF INSERT AS BEGIN
INSERT INTO my_table ( forename, surname) SELECT forename, surname FROM inserted
END
/************************************************ 3) - Do the insert ************************************************/
INSERT INTO my_table ( forename , surname ) OUTPUT inserted.my_table_id INTO @my_insert VALUES( @forename , @surname )
select @@identity -- expect this value in @my_insert table select * from @my_insert -- OK value without trigger - zero with trigger
/************************************************ 4) - Drop the trigger ************************************************/
drop trigger [dbo].[trig_my_table__instead_insert] go
/************************************************ 5) - Re-run insert from 3) ************************************************/ -- @my_insert now contains row expected with identity of inserted row -- i.e. OK
I have a quite big SQL query which would be nice to be used using UNION betweern two Select and Where clauses. I noticed that if both Select clauses have Where part between UNION other is ignored. How can I prevent this?
I found a article in StackOverflow saying that if UNION has e.g. two Selects with Where conditions other one will not work. [URL] ....
I have installed SQL Server 2014 and I tried to use tricks mentioned in StackOverflow's article but couldn't succeeded.
Any example how to write two Selects with own Where clauses and those Selects are joined with UNION?
It is possible to get the definition of an index in a script? I want the "Create index..." string so I can drop and recreate the index in a single statement. You can do it in the Query Analyzer object browzer with the "Script object..." options.
Hello, i would like to know if it's possible to generate automatically a word document or an excel document that will contain all the metadata definition, for example containing the source columns names, their datatype, and the destination with their datatypes, so that it would easy to create a data dictionnary .
I'm tasked with creating POCO (C# Class Object) and XML definitions for three different kinds of records coming from my input file. The problem is that I'm not sure how to do this within the SSIS framework. It seems to me that I can somehow define a class and include XML element tags in the definition, but I'm not sure where to look/who to ask/how to do that!
The goal is to be able to assign the data types and class attributes for various parts of each input record based on position, and to serialize the data as XML (and therefore my inputs to my Data Flow will be XML objects instead of a flat file, as I had been doing it...).
Can anyone point me at a good tutorial? Or a simple example?
I have a 2005 .Net 2.0 solution that includes two projects, a windows project and a Reporting Services project. The report viewer is apart of the windows project and I am wanting to open reports in the RS project but keep getting a 'the report definition has not been specified' error.
I set the ReportPath to point to the physical path of the RS project but it does no good.
Anyone have any idea how to run a report that is not apart of the project?

We are trying to create a view that references lengths in both metres and feet.
What we want to do is to create a baselength column which either holds the value of the metres column or calculates the metric value of the feet column if there is no value in the metric column.
We can do all the maths for the calculations etc, it is just putting the IF statement into the view to test the values that we are struggling with.
During work with creating, updating or deleting objects in a database, we use explicit name of the objects, for example DROP PROCEDURE myProc. By what the method can I avoid using the explicit name and get something like this: DROP PROCEDURE @myProc or DROP PROCEDURE id_myProc?
Plesae tell me the MSSQL Server equivalent of the below MySQL query .create table temp2(a varchar(23) comment 'male m');What is the use of specifying a keyword 'comment' in the column definition. Will it make any difference
I have set up a couple of views for a user but they want to be able to see the database table columns by doing right click on table and getting the columsn.
I tried to give the permissions to database by right clicking on database and doing the user and giving view defintion.
-- [TABLEA] contains no columns that can be inserted or the current user does not have permissions on that object.
I have a Live Database as well as the Test database with the same Definition
now i need to write a SQL to check identity of these two database tables,
i mean i need to check if the Test Database has got the Same Table definition as Live Database table definition ? In the same way how do i check for the Stored peocedures ?
I want to create a view on the table "workorder" that contains a serial id "woid". Another table, "wo_comment" contains multiple comments for each "woid".
I would like to create a view view_workorder with a column "allcomments" that is basically a concatenation of all the comments within the table "comment".
Table: workorder has columns: woid, startdate (plus many others) Table: wo_comment has columns: woid, comment, sequence
Desired View: view_workorder has columns: woid, startdate, allcomments
I tried to create a view as follows but get errors concerning the "CURSOR" statement making me wonder if I can use declarations and CURSORS within a view?
create view [workorder_view] as ( Select w.woid, w.startdate, cast( DECLARE @all_comments nvarchar(4000), @curr_comment nvarchar(256) DECLARE wo_comment_cur CURSOR FOR SELECT woc.Comments FROM WO_Comment as woc WHERE woc.woid = w.woid OPEN wo_comment_cur FETCH NEXT FROM wo_comment_cur INTO @curr_comment WHILE (@@FETCH_STATUS = 0) BEGIN Set @all_comments = @all_comments + @curr_comment FETCH NEXT FROM wo_comment_cur INTO @curr_comment END CLOSE wo_comment_cur; DEALLOCATE wo_comment_cur; as nvarchar(80000)) as COMMENTS
I am having an issue with generating a table for an report on the fly. I have been referring to the example on www.gotreportviewer.com and their example works fine but when i attempt to do my own version (by adding the table, I get the following error:
The report definition is not valid. Details: The element 'TableColumns' in namespace 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition' has incomplete content.
List of possible elements expected: 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition:TableColumn'.
From my understanding 'TableColumns' was not expected even though i reference it correctly in my code and I it is defined in the ReportDefinition. It also causes no problems for the example from the above website.
I need to keep a table indicating the number of "transactions" or Logical Units of Work (LUW) against each database each day. I know transactions are defined with a Begin and End statement but most of our software is from 3rd party vendors who don't use begin and end. How can I determine how many transactions (not necessarily I/O although that might be nice in the future) has occurred against each database. Books On Line does not address the question of transactions other than to say use the Begin/End statments. Any thoughts would be greatly appreciated. Thanks in advance Bill Bergen (1-302-636-6814)
Is there a difference in the following: DECLARE @T1 VARCHAR(50);
SET @T1 = (SELECT TOP(1) Col1 FROM MyTable); -- define variable first way SELECT TOP(1) @t1 = Col1 FROM MyTable; --
define variable second wayI did a quick test and not finding a difference, however I was told that if nothing is returned by the query the result would be different and that the first way is better.
I want to create a login with some restriction like the following...
1.I will create a login and ll mapped to a particular DB with the Database Role 'db_datarerader' only, 2.We wants to display the all objects under a DB but we don't want to provide the View Definition to that particular Login. 3.If we Deny the View definition option he can't able to see the Objects which are there under the DB. 4.So My Clear Question is we want to display the Object like tables ,Sps...etc and we don't want to allow him to view the definition of those objects....
I'd like to find out whether or not people grant VIEW DEFINITION to their developers in UAT and PROD environments. My view is that a developer shouldn't be able to touch a PROD environment at all (we also include UAT as PROD), and any issue in a production environment should be investigated by a DBA and escalated to the dev if necessary.
We hear about catalog table in documentation but is this the same asdatabase schema?What is the definiation of catalog table?What does it pertain to?Thanks--Message posted via http://www.sqlmonster.com
When I am trying to create an indexed view using group and COUNT(*), it gave me the following error:
€œMsg 10136, Level 16, State 1, Line 2 Cannot create index on view "AdventureWorks.Sales.vOrders" because it uses the aggregate COUNT. Use COUNT_BIG instead.€?
When I refered the SQL Books Online, I found the following statement: €œIf GROUP BY is present, the VIEW definition must contain COUNT_BIG(*) and must not contain HAVING€?.
Though my question is basic, I am curious to know the difference between COUNT() and COUNT_BIG(). The only difference I knew is COUNT_BIG() returns bigint. If this is the only difference, why can€™t we use COUNT() in indexed view definition and why COUNT_BIG() is allowed?
