问题 We are using the following script to calculate the median: SELECT [Period] = 'amountPeriodA', [Median] = AVG(x.amountPeriodA) INTO #mediantable FROM ( SELECT r.customer, r.amountPeriodA, [RowASC] = ROW_NUMBER() OVER(ORDER BY r.amountPeriodA ASC, customer ASC), [RowDESC] = ROW_NUMBER() OVER(ORDER BY r.amountPeriodA DESC, customer DESC) FROM #MyExample r ) x WHERE RowASC IN (RowDESC, ROWDESC-1, ROWDESC+1) Is it possible to generalise a script like this and then code it into the server so that

问题 Inside an SP I need to find out the Id's of some clients of the first account whose Code matches any of the second account's clients. I wrote the following query that works - SELECT DISTINCT cil.Id FROM ClientIdList AS cil INNER JOIN Client AS c1 ON cil.Id = c1.Id INNER JOIN Client AS c2 ON c1.Code = c2.Code WHERE c2.AccountId = 2 ORDER BY cil.Id Here ClientIdList is a single-column table-type variable which holds the Ids of the selected clients from the first account (and I need to use this

问题 I have created a stored proc on schema X that does a select across 10+ tables that are in schema X and Y. I created a database role DBRole and added a new AD Group Login to it. I thought all I needed to do was grant execute on x.MyStoredProc to DBRole, but I'm getting errors because of select permission.. Stored Procedure MYSCHEMA.MyStoredProc failed: The SELECT permission was denied on the object 'myTable', database 'Db', schema 'dbo'. I wondered if it was because the tables its failing on

问题 I am using SQL Server 2008 R2. I have a table called Messages where I store user messages each user send to other users.

问题 I have a table that I need to move a value from one column to another then set a new value in the original column. declare @foo table (A int, B int); insert into @Foo select 1, 0; update @Foo set B = A, A = 2; After the update does B always contain 1 or is this non deterministic behavior and it will sometimes have a value of 2 due to A being updated first (and all my tests have just never hit just right the conditions to have it be 2 )? As a followup question if the answer is " B will always

问题 I've got the following code which makes a connection to a db > runs a stored proc > and then moves on. I believe it is easy to get db programming wrong so it is important to be defensive : is the following defensive? (or can it be improved?) public int RunStoredProc() { SqlConnection conn = null; SqlCommand dataCommand = null; SqlParameter param = null; int myOutputValue; try { conn = new SqlConnection(ConfigurationManager.ConnectionStrings["IMS"].ConnectionString); conn.Open(); dataCommand =

问题 I am bulk importing data from a pipe-separated CSV file into SQL Server. The data is formatted like A|B|CCCCCC\r\n I have validated both that the file is in UTF-8 format and that lines are terminated with "\r\n" by viewing the CSV file in a hex editor. The command is BULK INSERT MyTable FROM 'C:\Path\File.csv' WITH (FIRSTROW=1, MAXERRORS=0, BATCHSIZE=10000, FIELDTERMINATOR = '|', ROWTERMINATOR = '\r\n') The third column originally was defined as CHAR(6) as this field is always a code exactly

问题 I have the table with the two columns namely cola and colb as shown below: Table : Test create table Test ( cola int, colb int ); Records I have entered are: Cola Colb ------------ 1 2 1 3 1 4 2 5 2 6 2 3 3 2 3 4 3 7 3 10 10 11 11 12 11 13 11 14 12 15 13 16 14 99 15 88 16 77 Note : Now I want to show the only records who are connected with value I have pass.
