Chapter 11: Writing Scripts and Batches This should take you down to a blank line (with no prompt of any kind), where you can enter in this: SELECT * FROM AdventureWorks2008.Production.Location Then press F6 and Return (this ends the creation of our text file). You should get back a message like: 1 file(s) copied. Now let’s retry our earlier query using a script file this time. The command line at the prompt has only a slight change to it: C:\>sqlcmd -Usa -Pmypass -i testsql.sql This should get us exactly the same results as we had when we ran the query using -Q. The major difference is, of course, that we took the command from a file. The file could have had hundreds — if not thousands — of different commands in it. Try It Out Generating a Text File with sqlcmd 342 As a final example of sqlcmd, let’s utilize it to generate a text file that we might import into another application for analysis (Excel for example). Back in Chapter 10, we created a view that listed yesterday’s orders for us. First, we’re going to take the core query of that view, and stick it into a text file: C:\copy con YesterdaysOrders.sql This should again take you down to a blank line (with no prompt of any kind), where you can enter this: USE AdventureWorks2008 SELECT sc.AccountNumber, soh.SalesOrderID, soh.OrderDate, sod.ProductID, pp.Name, sod.OrderQty, sod.UnitPrice, sod.UnitPriceDiscount * sod.UnitPrice * sod.OrderQty AS TotalDiscount, sod.LineTotal FROM Sales.Customer AS sc INNER JOIN Sales.SalesOrderHeader AS soh ON sc.CustomerID = soh.CustomerID INNER JOIN Sales.SalesOrderDetail AS sod ON soh.SalesOrderID = sod.SalesOrderID INNER JOIN Production.Product AS pp ON sod.ProductID = pp.ProductID WHERE CAST(soh.OrderDate AS Date) = CAST(DATEADD(day,-1,GETDATE()) AS Date) Again press F6 and press Enter to tell Windows to save the file for you.
We now have our text file source for our query, and are nearly ready to have sqlcmd help us generate our output. First, however, is that we need there to be some data from yesterday (none of the sample data is going to have data from yesterday unless you just ran the UPDATE statement we used in Chapter 10 to change to orders to yesterday’s date. Just to be sure of which update I’m talking about here, I mean the one shown in the views chapter. So, with this in mind, let’s run that statement one more time (you can do this through the Query window if you like): USE AdventureWorks2008 UPDATE Sales.SalesOrderHeader SET OrderDate = CAST(DATEADD(day,-1,GETDATE()) AS Date), DueDate = CAST(DATEADD(day,11,GETDATE()) AS Date), ShipDate = CAST(DATEADD(day,6,GETDATE()) AS Date) WHERE SalesOrderID < 43663; OK, so we have at least one row that is an order with yesterday’s date now. So we’re most of the way ready to go; however, we’ve said we want our results to a text file, so we’ll need to add some extra parameters to our sqlcmd command line this time to tell SQL Server where to put the output: C:\>sqlcmd -UMyLogin -PMyPass -iYesterdaysOrders.sql -oYesterdaysOrders.txt There won’t be anything special or any fanfare when sqlcmd is done running this — you’ll simply get your Windows drive prompt again (C:\ most likely), but check out what is in our YesterdaysOrders.txt file now: C:\>TYPE YesterdaysOrders.txt This gives us our one row: Chapter 11: Writing Scripts and Batches C:\>TYPE YesterdaysOrders.txt Changed database context to ‘AdventureWorks2008’.
