The first query returns me the results from multiple databases, the
second does the same thing except it puts the result into a #temp
table? Could someone please show me an example of this using the first
query? The first query uses the @exec_context and I am having a
challenge trying to figure out how to make the call from within a
different context and still insert into a #temp table.
DECLARE @exec_context varchar(30)
declare @sql nvarchar(4000)
DECLARE @DBNAME nvarchar(50)
DECLARE companies_cursor CURSOR FOR
SELECT DBNAME
FROM DBINFO
WHERE DBNAME NOT IN ('master', 'tempdb', 'msdb', 'model')
ORDER BY DBNAME
OPEN companies_cursor
FETCH NEXT FROM companies_cursor INTO @DBNAME
WHILE @@FETCH_STATUS = 0
BEGIN
set @exec_context = @DBNAME + '.dbo.sp_executesql '
set @sql = N'select top 10 * from products'
exec @exec_context @sql
FETCH NEXT FROM companies_cursor INTO @DBNAME
END
CLOSE companies_cursor
DEALLOCATE companies_cursor
-------------------------------------------------------------------------------------
CREATE TABLE #Test (field list here)
declare @sql nvarchar(4000)
DECLARE @DBNAME nvarchar(50)
DECLARE companies_cursor CURSOR FOR
SELECT NAME
FROM sysdatabases
WHERE OBJECT_ID(Name+'.dbo.products') IS NOT NULL
ORDER BY NAME
OPEN companies_cursor
FETCH NEXT FROM companies_cursor INTO @DBNAME
WHILE @@FETCH_STATUS = 0
BEGIN
set @sql = N'select top 10 * from '+@DBNAME+'.dbo.products'
INSERT INTO #Test
exec (@sql)
FETCH NEXT FROM companies_cursor INTO @DBNAME
END
CLOSE companies_cursor
DEALLOCATE companies_cursor
SELECT * from #Test
DROP TABLE #Test
