How to update running records in SQL Server -

-

Here below the table, I want to open the second row with the end of the first line and update it on so much. The closing column is calculated (opening + total) 

  ID total opening closing --------- ------------ - - ---------- 1 0 3015591.25 3015591.25 2 0 2146798.4 minus 3 0 3,015,591.25 minus 4 0 21 467 9 8.4 minus 5 0 3,015,591.25 minus 6 0 21 467 9 8.4 zero 7 0 3,015,591.25 zero 8 0 21467 9 8.4 Zero

and Output should be as follows: 

  Opening ID Total Closing --- - ------ -------- ---- ------------- 1 0 3015591,25 3015591,25 2 3015591,25 2146798,4 5162389,65 3 5162389.65 3015591.25 8177981.25 4 8177980.9 2146798.4 10324779.4 5 10324779.3 3015591.25 13340370.25 6 13340370.55 2146798.4 15487168.4 7 15487168.95 3015591.25 18502759.25 8 18502760,2 2146798,4 20649557,4

Any solution on this

WHILE A related answer to the loop.

- Execute your table DECLARE @tbl TABLE (ID INT, float, total float, closing float) --Testing values ​​insert in @tbl (ID, opening, total, closing) values (1,0,3015591.25,3015591.25) @tbl inserting values ​​(id, opening, total, closing) values ​​(2,0,2146798.4, zero) @tbl (id, opening, total, closing) values ​​(3,0) , 3,015,591.25, zero) put @tbl (ID, opening, total closing) values ​​(4, 0,2146798.4, zero) put @tbl (ID, opening, total closing) values ​​(5,0,30l559lk25 zero ) @tbl insert ( ED, open, total, closing) values ​​(6,02146798.4, zero) @tbl (ID, inserting in the opening, total, closing) values ​​(7,0,3015591.25, zero) @tbl (ID, inserting in the opening, overall, closing) values ​​(8,0,2l46798k4, zero) - - announced starting from dECLARE @StartCount INT, @TotalCount INT, @ select @OPENING float, @ off float @TotalCount = MAX (ID) TBL ; SET @StartCount = 2; While (@StartCount & lt; = @TotalCount) start selecting @OPENING = IsNull (closing, 0) Where ID select @tbl WHERE id = @StartCount - 1 of @CLOSING = @tbl (@OPENING + total) = @StartCount update @TBL SET opening = @OPENING, closing = @ clipping ID WH = id = @ Startkount sELECT @StartCount = @StartCount + select 1 eND * with @ ttbl

hope That it helps

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job.

You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the
