I need the start and end time of consecutive records of the same vehicle with 0 speed ordered by date_time. If there is more than one consecutive record with zero speed it needs to be grouped together.
I am fairly new to transact SQL and I am having difficulty retrieving the set of records I require given the data shown below. I want to be able to filter the records just to return the records that have the minimum securityorder for each unique secsyscode. I suspect I need to use min or group by to achieve the desired affect but cannot seem to get it right
any help would be appreciated
eg in the following secsyscode, securitytypecode and securityorder are integers and securityCode is a char(16).
and in this table, i have found index for Name1-Nam4,
i don't why sql below is very slow?
select Name1, sum(C1), ...., Sum(C100) from ( select Name1, Name2, sum(C1) as C1, ...., Sum(C100) as C100 from ( select Name1, Name2, Name3, sum(C1) as C1, ...., Sum(C100) as C100 from ( select Name1, Name2, Name3, Name4, C1, ...., C100 from My_Table group by Name1, Name2, Name3, Name4 ) as T group by Name1, Name2, Nam3 ) as T group by Name1, Name2 ) as T group by Name1
I have just been running a query which I was planning on improving by removing a redundant GROUP BY (there are about 20 columns, and one of the columns returned is atomic, so will mean that the "group by" will never manage to group any of the data) but when I modified the query to remove the grouping, this actually seems to slow the query, and I can't see why this would be the case.
Both queries return the same number of rows (69000), as I expected, and looking at the query plan, then they look nearly identical, other than at the start, there is a "stream aggregate" and "sort" being performed. The estimated data size is 64MB for the non-grouped query (runs in 6 min 41 secs), vs 53MB for the aggregated query (runs in 5 min 31 secs), and the estimated row size is smaller when aggregated.
Can rationalise this? In my mind, the data that is being pulled is identical, plus there is extra computation for doing an unnecessary aggregation, so the aggregated query should be unquestionably slower, but the database engine has other ideas; it seems to be able to work more quickly when it needs to do unnecessary work :) Perhaps something to do with an inefficient query plan for the non-aggregated query? I would have thought looking at the actual execution plan might have made this apparent, but both plans look very similar.
Edit: More information, the "group by" query had two aggregations on it, a count of one of the columns, and an average of another one. I changed this so that it was just "1" instead of the count, and for the average, I changed it to be the expression within the average aggregate, since the aggregation effectively does not do anything.
writing the query for the following, I need to collapse the continuity. If the termdate for an ID is one day less than the effdate of the next id (for the same ID) i need to collapse the records. See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.
The simple 'select' from ISQL/W is taking more than 2 mins. for getting 20000 records. Is it normal? The time that is shown at bottom of window is the correct measure of response time or is there any other way?
Hello! suppose i have two tables, table1 columns(empcode (pk), empDept) and table2 columns(empcode (FK),Date,Attendance) i wanted to write a query to get output like DEPT ABSENT ----------------------------- Accounts 10 EDP Section 0 ** Admin 2 Stationary 0**
if no employee is absent in the department it has to display Zero
Can Somebody please show me how to acheive this, using the order details in Northwinddatabase or any other good example. as much details as possible. Many Thanks!

My SQL is very basic. How do I create a query that will accept a parameter, an integer, and based on the integer, locate all the matches in a db? SELECT COUNT(*) AS Expr1, tblArticle.ArticleIDFROM tblArticle INNER JOIN tblArticleCategory ON tblArticle.ArticleCatID = tblArticleCategory.ACategoryIDGROUP BY tblArticle.ArticleID This isn't setting up the query to request a parameter.What am I doing wrong here? I"m trying to get the total number of articles for a particular category ID.
I have a table T (a1, ..., an, time, id). I need to select those rows that have different id (GROUP BY id), and from each "id group" the row that has the latest field 'time'. Something like SELECT a1, ..., an, time, id ORDER BY time DESC GROUP BY id. This is the wrong syntax and I don't know how to handle this.
I have a query to insert records into a table based on a request but the query can only read one record at a time. How do i change the query such that it is able to read multiple records. In the below query i was able to input only 1 request which is 149906.
Query
declare @num_of_times int declare @Count INT DECLARE @newrequestid varchar(50) DECLARE @Frequency VARCHAR(25), @RequestId INT, @x INT, @Max INT, @RptDesc INT SET @RequestId = 149906 SET @x = 1
I've been able to get this select query to work, but I'm not sure how to modify it to turn it into a DELETE query:
USE QSCTestENG select p.[testid], COUNT(c.[testid]) FROM [dbo].[tblTestHeader] p left outer join [dbo].[tblTestMeasurements] c ON p.[testid]=c.[testid] where p.[model] = 'XPPowerCLC125US12' group by p.[testid] having COUNT(c.[testid]) <>48;
I'm trying to do some analysis on duplicate records based off of several match keys. I have a data set of approximately 30,000 people and the goal is to determine how many duplicate matches are in the system.
How would I write an SQL statement that looks for the following pieces of information. (I'm not using one person as an example; I need to do an analysis on the entire data set)
First name (exact match) Last name (exact match) Address line 1 (exact match) Postal code/zip (exact match)
First Initial (exact match) Last name (exact match) DOB exact match Postal code/zip (exact match)
Generating the 4 lines is not the issue; I call 3 functions to do that together with cross apply.One function to get all dates between the start and end date (dbo.AllDays returning a table with only a datevalue column); one function to have these dates evaluated against a work schedule (dbo.HRCapacityHours) and one function to get the absence records (dbo.HRAbsenceHours) What I can't get fixed is having the correct hours per line.
I have a a Group By query which is working fine aggregating records by city. Now I have a requirement to focus on one city and then group the other cities to 'Other'. Here is the query which works:
Select [City]= CASE WHEN [City] = 'St. Louis' THEN 'St. Louis' ELSE 'Other Missouri City' END, SUM([Cars]) AS 'Total Cars' From [Output-MarketAnalysis] Where [City] IN ('St. Louis','Kansas City','Columbia', 'Jefferson City','Joplin') AND [Status] = 'Active' Group by [City]
Here is the result:
St. Louis 1000 Kansas City 800 Columbia 700 Jefferson City 650 Joplin 300
When I add this Case When statement to roll up the city information it changes the name of the city to 'Other Missouri City' however it does not aggregate all Cities with the value 'Other Missouri City':
Select [City]= CASE WHEN [City] = 'St. Louis' THEN 'St. Louis' ELSE 'Other Missouri City' END, SUM([Cars]) AS 'Total Cars' From [Output-MarketAnalysis] Where [City] IN ('St. Louis','Kansas City','Columbia', 'Jefferson City','Joplin') AND [Status] = 'Active' Group by [City]
Here is the result:
St. Louis 1000 Other Missouri City 800 Other Missouri City 700 Other Missouri City 650 Other Missouri City 300
Hi everyone, I'm working with SSRS 2000 and I have my report grouped by =Fields!ID.Value , but each ID has just the ID#, or an A or OT at the end. EX. ID# 12345, is divided and shows me like if there are 3 different Employees: 12345, 12345-A, and 12345-OT. I want 12345 and 12345-A, to be grouped in one, and 12345-OT, be displayed seperately. Is this possible? Do I have to write a special command??? all help is useful so please help.
There are two tables. the second one is a table that contains fields based on which the exclusion logic has to be written. It has 5 fields and there may be data in all of them or only in some of them.
The first and second table have one field in common - the Account number.(ACCT_NUM)
the exclusion is based in steps..
1) if it has all the fields in the second table for that account number, then compare all of them.. 2) if only 4 of them are present,compare and check for null for the rest 3) if only 3 of them are present,compare and check for null for the rest 4) if only 2 of them are present,compare and check for null for the rest.
I need to update the Tn column from the default 9999 for the 3 rows in this table where the dealid is 12345 based on the value in the datex column so the row with the 'highest ie most recent date' gets a 0. I then need to assign the value 1 to the next highest and so on until all rows (in this case 3) get incrementing integer values. It's easy with a cursor but can't get my head round doing it in a set-based way Any ideas
I'm no expert at SQL, I can't figure out how to solve that problem.
The following statement:
SELECT TeamMemberId, max(MonthId) as MonthId FROM Position INNER JOIN [Month] m INNER JOIN [Year] y ON m.YearId = y.Id AND (y.Id = @yearId OR y.Id < @yearId) ON m.Id = Position.MonthId GROUP BY TeamMemberId
Returns TeamMemberId MonthId 1 14 6 20
which is exactly what I want: The greates MonthId for each TeamMember in a specific year.
But I need more data for this postition, like the PositionName.
But the statement:
SELECT TeamMemberId, max(MonthId) as MonthId, PositionName FROM Position INNER JOIN [Month] m INNER JOIN [Year] y ON m.YearId = y.Id AND (y.Id = 2 OR y.Id < 2) ON m.Id = Position.MonthId GROUP BY TeamMemberId, PositionName
Returns TeamMemberId MonthId PositionName 1 2 ***. d. Geschäftsführung 6 20 ***. d. Geschäftsführung 1 14 CEO 6 16 CEO
The red rows are the ones I wanna get. How can I achieve that only the max. MonthId rows are returned, even when I need to select more columns? Any help is much appreciated.
Currently working on a upload module where in the data from excel file is imported to the destination tables. Data in the excel sheet comes in phases. All excel sheet columns data don't come at first shot. The excel sheet's data is dumped into temporary tables which inturn is looped using cursor's and gets finally updated to the actual tables.
Now, the problem I am facing is how do I update columns of the actual table with the data (i.e NON NULL values) available in the temporary table without tampering the data allready present in actual table.
Ideally what required is, update the actual table column values with the corresponding columns of temporary table ONLY for Non NUll column values of temporary table.
Temporary and Destination tables have 85 columns each. I don't want to write 85 update queries.
The scenario which I am facing is given below with 2 columns as an example.
1. Table 1 :- tbl_source (Temporary Table) has two columns src_Col1 & src_Col2 2. Table 2 :- tbl_destination (Actual Table) has two columns dest_Col1 & des_Col2
Scenario -1 ---------------
tbl_Source Sample Data (after excel import to the temporary table) ------------------------
src_Col1 src_Col2 ------------------ 50 NULL
tbl_Destination Sample Data ------------------------
dest_Col1 dest_Col2 ------------------ 50 NULL
Scenario -2 ---------------
tbl_Source Sample Data ------------------------
src_Col1 src_Col2 ------------------ NULL 100
tbl_Destination Sample Data ------------------------

How can we use the SQL INSERT statement in the stored procedure to create a table in a user specified filegroup? Table1 will be created by using the following SQL script and will be placed in a default filegroup. The question is can this table been created in a specified filegroup other than default filegroup.
INSERT INTO Table1(col1,col2) SELECT col1,col2 FROM Table2
Example, userA table assign to userA filegroup. userB table assign to userB filegroup. Usually by using CREATE statement you can put the table on a specific filegroup as long as a predefined filegroup has been hard coded in the script. I appreciate any inputs.
I am trying to add "Remote Desktop Users" as a login group to SQL Server 2005 (i.e. so they can log into management studio). I get a "Not Found Error" (see below). But it is of course found, because I selected it :-) What is going on here? I see the "Administrators" group and various SQL Server groupls added automatically there, so there must be a way, right?
I know I can add each user in the group individually, but that seems overkill when I can just use the group in which they are contained.
Here is the error I get:

I want to copy FirstName and LastName cells from table1 to table2. Which FirstName and LastName cells depend on the username, i.e. which person has logged in. Q1) How can this be done? (I have chosen to SELECT from Table1 and output to variables (C# code); then INSERT these variables into Table2. [Finding it very difficult]). Any suggestions/comments would be appreciated. Thank you in advance.
Hi. I have a table called "Maxes" with three fields: Exercise_ID, weight, and date. This is for journaling my weightlifting progress. What I want my query to do is this: Return just one record for each Exercise_ID, and only the one with the most recent date.
I tried this:
Code:
SELECT DISTINCT Maxes.Exercise_ID, Maxes.Date_Maxed, Maxes.[Max Weight] FROM Maxes ORDER BY Maxes.Date_Maxed DESC;
but it doesn't quite work. Can someone show me how to do this?
