UPDATE [com\spprod].[aspnetdb].[dbo].[Communities_Groups] as t1 SET t1. Show = (Select t2from [spdb com\sp QA].[aspnetdb].[dbo]. Groupd ID) UPDATE [com\spprod].[aspnetdb].[dbo].[Communities_Groups] SET Show = t2FROM [com\spprod].[aspnetdb].[dbo].[Communities_Groups] t1 INNER JOIN [spdb com\sp QA].[aspnetdb].[dbo]. Customer Address FROM [,2345].[Production Database].[dbo].[Customers] production INNER JOIN [Backup Database].[dbo].[Customers] backup Server ON production. The values in column 4 & 5 are dynamic (ie not the same each time) background on the table.

These exercises allow you to try out your skills with the UPDATE statement.Person Log(Person Name, Address, Mobile, FK_Person Id) SELECT Person. Person Log(Person Name, Address, Mobile, FK_Person Id) SELECT Person. I would also recommend you use an auto incrementing integer as the key you use to map between the 2 tables. I have two tables in different databases on the same database server.
