TSQL Writing into a Temporary Table from Dynamic SQL

Question

Consider the following code:

SET @SQL1 = \'SELECT * INTO #temp WHERE ...\'
exec(@SQL1)
SELECT * from #temp  (this line throws an error that #temp doesn\'t ex         


        

Answer 1

Try ##temp Because your dynamic query is executed on an other fibre so you cannot see its local temporay table. instead if you declare your temporary table like global it make a sens.

Answer 2

You can create temp before exec and use exec to populate the temp table.

Answer 3

An example, look at "into"

SELECT o.OrderID, o.OrderDate, od.UnitPrice, od.Quantity,
       c.CustomerID, c.CompanyName, c.Address, c.City, c.Region,
       c.PostalCode, c.Country, c.Phone, p.ProductID,
       p.ProductName, p.UnitsInStock, p.UnitsOnOrder
INTO   #temp
FROM   Orders o
JOIN   [Order Details] od ON o.OrderID = od.OrderID
JOIN   Customers c ON o.CustomerID = c.CustomerID
JOIN   Products p ON p.ProductID = od.ProductID

Answer 4

Didn't find a workable solution that did everything I needed so I switched to using ##global temp tables instead.

Answer 5

Another method is to use all code inside the dynamic SQL

SET @SQL1 = 'SELECT * INTO #temp WHERE ...
SELECT * from #temp  ' 
exec(@SQL1) 

Answer 6

Can you not put your select after the insert into with a ; delimeter and run the two statements together?
