SQL database backup solution

The backup command: BACKUP DATABASE test to DISK ='C/dfasd.bak'

1, Query specifies all the tables in the database name

Select TABLE_NAMEFROM.INFORMATION_SCHEMA.TABLESWhere TABLE_TYPE database name='BASE TABLE'

2, Check out all the fields and precision specified in the table

select a.name,

case a.precision

when 0 then

case a.is_ansi_padded

when 1 then

convert(nvarchar(15),b.name+'('+convert(nvarchar(10),a.max_length)+')')

when 0 then

b.name

end

else

case a.scale

when 0 then

b.name

else

b.name+'('+convert(nvarchar(10),a.precision)+','+convert(nvarchar(10),a.scale)+')'

end

end

as typelengthfrom sys.columnsa left join sys.typesb on a.system_type_id=b.system_type_idand a.user_type_id=b.user_type_idwhere a.object_id=(select object_id from sys.objectswhere name ='Table name');

3, Check out the definition of all tables in the database in SQL
