If item number is same then its stock should be added and then replace the present stock in the database with same item number. I am able to add stock from the csv file to the database with same item numbers in the database but I am not able to replace stock. Here is my code: string sql_select = "select count(*) from PRODUCTS where item_no= '" + itemNo + "'

问题 I have a child package where the ConnectionString property of a Connection Manager is set by a Parent Package Variable Configuration. I set up a script task that brings up a message box with the value of the ConnectionString property right before the dataflow task. `MessageBox.Show(Dts.Connections["CPU_*"].ConnectionString.ToString());` When I run the parent package, the message box shows that the connection string is changing with every iteration, but in the dataflow it always draws the data

问题 I'm having issues with SQL Server's BCP . I'm not getting an error message but the command is also not writing anything to the path specified. Here is my code: In this scenario, the only variable not accounted for in the code below is @MESSAGE which is a NVARCHAR(MAX) and will take up most of that space so VARCHAR(8000) won't be nearly big enough. DECLARE @OUTPUT_TABLE VARCHAR(255) = '##temp' + CONVERT(VARCHAR(12), CONVERT(INT, RAND() * 1000000)) DECLARE @RESULT INTEGER DECLARE @OUTPUT

问题 I have two sql servers, SE1 and SE2, they are basically having the same schema, but each one has its own usability. I need to find a query to copy some rows from SE1.Table1 Where Destination Like '%HR%' to SE2.Table2. Is there such query ?? Thx in advance. 回答1: I find the easiest way is to add a remote connection from one to the other. So, go to the second server and do: sp_addlinkedserver SE1 Then you can go to the database you want to use and do something like: insert into database.dbo

问题 I have a View which is keyed on both ChargeID and CustomerID (Charge can be split between multiple customers). The View consists of 2 tables (heavily simplified here, actual tables have ~40 columns each): CREATE TABLE tblCharge (ChargeID int NOT NULL, ParentChargeID int) CREATE TABLE tblChargeShare (ChargeShareID int NOT NULL, ChargeID int NOT NULL, CustomerID int, TotalAmount money, TaxAmount money, DiscountAmount money) The View just joins these both together: CREATE VIEW
