sql server synchronize tables between databases

For the first time, SQL Server appeared on the top ten rankings of "all environments" (This ranking includes all databases running in Microsoft Windows and non-Windows environments ), this indicates that SQL Server has ranked among the OLTP

, but cannot be separated. That is to say, if a group has user account management permissions, it can not only create user accounts, but also delete user accounts. That is to say, Microsoft's SQL Server database is not as detailed as Oracle in terms of permission design. Because of this, Oracle databases are more flexible in permission management than

Sometimes we may import CSV data to a database table, such as when performing report analysis.I think it's hard to solve this problem at all.ProgramPersonnel! But it would be better if SQL server can complete this task!Yes, SQL Server does have this function.First, let's take a look at the CSV file, which is saved in m
