I can easily find user created stat in a databaseSELECT * FROM DB.sys.stats WHERE user_created=1But how do I determine what tables those stats are in? with over 6000 tables I don't feel like looking through all the tables.
View 2 RepliesHello group.I have an issue, which has bothered me for a while now:I'm wondering why the column statistics, which SQL Server wants me tocreate, if I turn off auto-created statistics, are so important to theoptimizer?Example: from Northwind (with auto create stats off), I do the following:SELECT * FROM Customers WHERE Country = 'Sweden'My query plan show a clustered index scan, which is expected - no indexexists for Country. BUT, the query plan also shows, that the optimizer ismissing a statistic on Country, which tells me, that the optimizer wouldbenefit from knowing this.I cannot see why? (and I've been trying for a while now).If I create the missing statistics, nothing happens in the query plan (andwhy should it?). I could understand it, if the optimizer suggested an indexon Country - this would make sense, but if creating the missing index, queryanalyzer creates the statistics with an empty index, which seems to me to beless than usable.I've been thinking long and hard about this, but haven't been able to reacha conclusion :) It has some relevance to my work, because allowing theoptimizer to create missing statistics limits my options for designingindexes (e.g. covering) for some rather wide tables, so I'm thinking why notturn it off altogether. But I would like to know the consequences - hopesomebody has already delved into this, and knows a good explanation.RgdsJesper

Getting events in the default trace saying missing column statistics on a column...
1.The column is the primary key column ( identity )
I have been asked to create a report for one of our clients. The report is pretty basic but I am concerned about the overheads with my planned approach.The report is at a table and field grain to include values for:
* Min column value
* Max column value
* Number of discrete values
* Number of populated values (not NULL)
My current plan is to have a cursor over a limited view of sys.tables and sys.columns that will run a dynamic SQL query to import the results into a table that I can then output.There must be a better way of doing this and I don't have access to any DQS services.

Is there anyway to find the permissions assigned to user. What level of access the user has in each db and the tables & is he able to see jobs. Each object and permissions
View 6 Replies View RelatedWe have a production server "prod" which has a user say 'test' that lets the users connect to the application and a logon trigger which stops them from connecting to the server through SSMS. I log ship 'prod' to the 'rep' database and the user 'test' is obviously created in the logshipped database 'rep' during the logshipping.
Now the login 'test' does not have any login from server 'rep', But people can still login to the 'rep' server and query the 'rep' db . I checked with SUSER_SNAME and found the SID of the user in rep server which I never created and which is not even present in the login names, Even If I create a new username in the 'prod' db, after logshipping the new user is replicated in the 'rep' server.
How can i assign permissions to a newly created users as of an existing user?

The following is sample data I am dealing with.
SELECT * INTO TEMP

UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '02-01-2014' AS STARTDATE, '02-28-2014' AS ENDDATE
UNION

UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '05-01-2014' AS STARTDATE, '05-31-2014' AS ENDDATE) X
I need to extract the date that the value in CODE column changes to another code for each value of CATEGORY and if there is no change, to record the original CODE value and its startdate for each CATEGORY.
I'm trying to come up with a query for this data:
CREATE TABLE #Visits (OpportunityID int, ActivityID int, FirstVisit date, ScheduledEnd datetime, isFirstVisit bit, isRepeatVisit bit)
INSERT #Visits (OpportunityID, ActivityID, FirstVisit, ScheduledEnd)
SELECT 1, 1001, '2014-08-17', '2014-08-17 12:00:00.000' UNION ALL
SELECT 1, 1002, '2014-08-17', '2014-08-17 17:04:13.000' UNION ALL
SELECT 2, 1003, '2014-08-18', '2014-08-18 20:39:56.000' UNION ALL
[Code] ....
Here are the expected results:
OpportunityIDActivityIDFirstVisitScheduledEndisFirstVisitisRepeatVisit
110012014-08-172014-08-17 12:00:00.00010

210042014-08-182014-08-18 18:00:00.00010
[Code] ....
Basically I'd like to mark the first Activity for each OpportunityID as a First Visit if its ScheduledEnd falls on the same day as the FirstVisit, and otherwise mark it as a Repeat Visit.
I have this so far, but it doesn't pick up on that the ScheduledEnd needs to be on the same day as the FirstVisit date to count as a first visit:
SELECT*,
CASE MIN(ScheduledEnd) OVER (PARTITION BY FirstVisit)
WHEN ScheduledEnd THEN 1
ELSE 0
END AS isFirstVisit,
CASE MIN(ScheduledEnd) OVER (PARTITION BY FirstVisit)
WHEN ScheduledEnd THEN 0
ELSE 1
END AS isRepeatVisit
FROM#Visits
How do you find stale stored procedures ?
In a scenario where a developer created a slight modification of a stored procedure because he was afraid of breaking something else and took the easy way out, and a few more later down the line, multiple versions of a stored proc. doing slightly different things are just laying around.
"Last used" would be useful piece of information to determine the most recent date a stored procedure was called, either by the application itself or by another stored procedure itself called by the application.
Any stored proc not used for more than say 6 months would then be identified as a candidate for clean-up.
So - short or creating - after the fact - a trigger to update the usage date upon each call - which means a lot of work and no result for the next six months, how can one go about this ?
And could this be done in SS2K8 ?
I am supporting a SQL Server 6.5 databases that users query using
pre-configured reports. The reports use views, stored procedures,
and triggers set up by the programmers and accessed thru a client
on the workstation.
I need to be able to count which users log in (SQL Server security),
how often, and either which reports they use or what tables they
select.
I do not have access to the WindowsNT server, so the solution
has to work with SQL Server SA rights.
Thanks for any suggestions.

I am trying to build a select statement that will
1). find records where a duplicate field exists.
2.) show the ItemNo of records where the Historical data is ' '.
I have the query which shows me the duplicates but I'm stuck when trying to only show records where the Historical field = ' '.
Originally I thought I could accomplish this goal with a sub query based off of the original duplicate result set but SQL server returns an error.
Below you will find a temp table to create and try in your environment.
create table #Items
(
ItemNovarchar (50),
SearchNo varchar (50),
Historical int
[Code] ....
Ultimately I need a result set that returns 'ATMR10 MFZ N', and 'QBGFEP2050 CH DIS'.
I've got a fairly large hierarchy table and I'm trying to put together a query to find the lowest level descendants of the hierarchy. I think there must be some way to use the "Breadth-first" approach that's stated in the MSDN technet sites about SQL Server HierarchyID but i'm not sure how to write the necessary T-SQL to traverse that. I know I can get all the descendants of a parent node like this
SELECT *
FROM AdventureWorks2012.HumanResources.Employee
WHERE OrganizationNode.IsDescendantOf(@ParentNode) = 1
However, this query returns all levels for that parent's branch. If I just wanted list of employees that were at the lowest level of the branch(es) for this parent node, how would I do this?
I would like to know if there is a way to find out who changed a users roles/access WITHOUT using the audit function. For example, if a user account was created and given SA access then changed to read only, how can I find out who made that change? I tried searching for an answer, but kept getting no results. I'm thinking this may tie into the sys.sysusers view?

Hi,
I have founde such a nice code to create statements for dropping all statistics in a database.
DECLARE @tblname sysname, @statname sysname, @sql nvarchar(2000)
DECLARE c CURSOR FOR
SELECT object_name(id), name FROM sysindexes WHERE INDEXPROPERTY(id, name, 'IsStatistics') = 1
OPEN c
FETCH NEXT FROM c INTO @tblname, @statname
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sql = 'DROP STATISTICS [' + @tblname + '].[' + @statname + ']'
PRINT @sql
FETCH NEXT FROM c INTO @tblname, @statname
END
CLOSE c
DEALLOCATE c
Please help me with changing this code to take care only on indexes from my own tables (no system ones).
Thanks for your help.

Hello!
Is there any way to determine index usage statistics for a given table?
For examle, I have a table, with three indices. I need to know how many times each index was used. Is it possible?
And second part of question: I need to know, which user overloads my base with their giantic queries. Is there any way to determine, how many system resources each of user's sessions uses?
MS SQL Server 2000 Enterprise Edition.
Thank you!
I have a four tables called plandescription, plandetail and analysisdetail. The table plandescription has the columns DetailQuestionID which is the primary and identity column and a QuestionDescription column.
The table plandetail consists of the column PlanDetailID which the primary and identity column, DetailQuestionID which is the foreign key attribute of plandescription table and a planID column.
The third table analysisdetail consists of a analysisID which the primary and identity column, PlanDetailID which is the foreign key attribute of plandetail table and a scenario.
Below is the schema of the three tables
I have a two web form that will insert, update and delete data into these three tables in a two transaction. One web form will perform CRUD operations in plandescription and plandetail table. When the user inserts QuestionDescription and planid in this web form, I will insert the QuestionDescription Value in the plandescription table and will generate a DetailQuestionID value and this value is fed to the plandetail table with the planid. Here I will generate a PlanDetailID.
Once this transaction is done, I will show the second web form in which the user enters the scenario and this will be mapped with the plandescription using the PlanDetailID.
This schema cannot be changes as this is the client requirement. When I insert values I don’t have any problem. However when I update existing data, I need to delete existing PlanDetailID in the plandetail table and recreate PlanDetailID data for that DetailQuestionID and planID. This is because, the user will be adding or deleting a planID associated with the QuestionDescription.
Once I recreate PlanDetailID for that DetailQuestionID and planID, I need to update the old PlanDetailID with the new PlanDetailID in the third table analysisdetail for the associated analysisID.
I created a #Temp table called #DetailTable to insert the values analysisID, planid and old PlanDetailID and new PlanDetailID so that I can have them in update statement once I delete the data from plandetail table for that PlanDetailID.
Then I deleted the plandetailid from the plandetail table and recreate PlanDetailID for that DetailQuestionID. During my recreation I fetched the new PlanDetailID’s created into another temp table called #InsertedRows
After this I am running a while loop to update the temp table #DetailTable with the newly created PlanDetailID for the appropriate planID’s. The problem is here. When I have the same number of planID’s for example 2 planID’s 1,2 I will have only two old PlanDetailID and new PlanDetailID for that planID and analysisID.But When I add a new PlanID or remove a existing planID I am getting null value for that newly added or deleted planID. This is affecting my update statement of analysisdetail table as PlanDetailID cannot be null.
I tried to remove the Null value from the #DetailTable by running the update statement of analysis detail in a while loop however its not working.
DECLARE @categoryid INT = 8
DECLARE @DetailQuestionID INT = 1380
/*------- I need the query to run for the below three data.
Here i'm updating my planids that already exists in my database*/

View 9 Replies View RelatedI'm designing a new database which will be the back-end to a heavily-used web-based application (all these terms are relative - I guess the use won't be that heavy in the grand scheme of things, I'm only talking 100 users or so at the very most). Data from the old application database will be migrated to this one, and the old database is around 7GB in size after 5 years of use.
I have two different ways of linking some tables in mind, one which is slightly more complex than the other but which potentially has benefits over the simpler method. However, I'm concerned that I might be 'over-cooking' the design, and that performance would suffer as a result, so I've tried creating the two different versions of the database (the part of it I'm concerned with, anyway), one for each of the solutions I've got in mind, migrated the data into the relevant tables and carried out some queries on the data to collect some statistics.
The problem is that, whilst I can see that the more complex method is more expensive, as expected, I don't really understand if the difference is significant. Since I don't know what the numbers in the Client Statistics window actually mean (there are no units! I'm guessing times are in milliseconds?), or how much of real-world impact the difference will have, I'm finding it hard to interpret my statistics and come to a decision.
Querying the entirety of my tables to return ~20,000 records listing one column from each of the main tables I'm playing with, the simpler method had a Total Execution Time of 199, and the more complex a Total Execution Time of 272. Is that the statistic I should be most concerned with? Is that a difference I should be concerned about? Is the difference likely to be magnified when the database is much larger and in use, such that a difference of 73 milliseconds in this test scenario could end up being as much as a whole second in production, for example?
