如何使用 EF.Core Database First 包含特殊字符 $ 脚手架表

Question

I have the following table in our SQL Server:

[prod].[dbo].[My Company$Customer]

I want to Scaffold this table with:

Scaffold-DbContext "Server=SQLPROD;Database=prod;Trusted_Connection=True;integrated security=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -table "dbo.My Company$Customer"

But it will always give me the following error:

Unable to find a table in the database matching the selected table

If I omit the -table switch everything works fine, but I get ALL tables, which are A LOT and I don't need them. So how can I use the -table switch correctly? I am using ef.core 2.2.1

Answer 1

In SQL Server, if you have special characters in your table names (eg spaces or anything that isn't a letter or number) then you need to surround the object name with square brackets. So your command line would become something like this:

Scaffold-DbContext "<connection-string>" 
    Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models 
    -table "[dbo].[My Company$Customer]"

You strictly don't need the square brackets around the schema ( dbo ) but there's no harm in including them there too.

使用 EF Core 3.1 我不得不转义 $ 字符。

Scaffold-DbContext "Server=myServer;Database=myDB;User Id=sa;Password=xyz;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -table "[dbo].[My Company`$Product]"
