Can we Scaffold DbContext from selected tables of an existing database
Package Manger Console (MySql)
Scaffold-DbContext "server=localhost;port=3306;user=root;password=yourpassword;database=sakila" MySql.EntityFrameworkCore -OutputDir Models -Tables actor,film,film_actor,language -f
Package Manager Console (MSSQL)
Scaffold-DbContext "Server=desktop-vd5sscb;Initial Catalog=databaseName;Integrated Security=True" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -f
Package Manager Console (Sqlite)
Scaffold-DbContext "data source = yourdbname" Microsoft.EntityFrameworkCore.Sqlite -OutputDir Models -f
For Sqlite The default db dir is your project folder... where controller folders are located
Force tag will update the existing selected models/files in the output directory.
Scaffold-DbContext "Server=(localdb)\v11.0;Database=MyDB;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -t User, Role -f
.NET Core CLI:
dotnet ef dbcontext scaffold "server=localhost;port=3306;user=root;password=mypass;database=sakila" MySql.Data.EntityFrameworkCore -o sakila -t actor -t film -t film_actor -t language -f
Package Manager Console in Visual Studio:
Scaffold-DbContext "server=localhost;port=3306;user=root;password=mypass;database=sakila" MySql.Data.EntityFrameworkCore -OutputDir Sakila -Tables actor,film,film_actor,language -f
EF Core,MS SQL PM :
Scaffold-DbContext "server=PC\SQL2012;user=test;password=test123;database=student" Microsoft.EntityFrameworkCore.SqlServer -OutputDir student-Tables stu.names,stu.grades -f

One can solve the problem by usage of dotnet ef dbcontext scaffold command with multiple -t
(--table
) parameters. It allows to specify all the tables, which needed by imported (scaffolded). The feature is described initially here.
It is possible to specify the exact tables in a schema to use when scaffolding database and to omit the rest. The command-line examples that follow show the parameters needed for filtering tables.
.NET Core CLI:
dotnet ef dbcontext scaffold
"server=localhost;port=3306;user=root;password=mypass;database=sakila"
MySql.Data.EntityFrameworkCore -o sakila
-t actor -t film -t film_actor -t language -f
Package Manager Console in Visual Studio:
Scaffold-DbContext "server=localhost;port=3306;user=root;password=mypass;database=sakila"
MySql.Data.EntityFrameworkCore -OutputDir Sakila
-Tables actor,film,film_actor,language -f
