For example, how to add associations for two tables, cascade update and delete. I checked it at night and found that two methods can be used. Trigger method:Create trigger trg

Because of accidental operation, in Enterprise Manager mistakenly deleted the database table, then mistakenly deleted the table data what to do?A lot of people's usual practice is to recover from the log first, if the recovery from the log is not possible from the MDF file itself.The first thing to do when you delete data by mistake is to detach the database, stop the database service, and then copy the MDF and LDF.Recover data from MDF files applied to the customer database a few years ago, but

allowed per column.3, check the constraintsThe check constraint sets the check condition for values in the input column or the entire table, and can limit the input values to ensure the integrity of the database.

For example, to define an age ages field, you can limit the range of values inside the age field to between 0 and 150 by creating a check constraint (>=0 and age Only one check constraint
