The same table and different databases cannot be added to select insert.Therefore, you must enter a stored procedure to indicate that the insert statement will generate data for you.Of course, the number of data tables is too large. You 'd better use another method. Copy codeThe Code is as follows:Create proc [dbo]. [spGenInsertSQL] (@ tablename varchar (256 ))AsBeginDeclare
