EF Core ToQueryString() 不包括架构

Question

I am trying to use SqlDependency, which requires a query as a string which specifies the schema (dbo.[table name]) but EF Core ToQueryString does not include dbo.

Is there another way to get a query from Ef core that includes the dbo keyword or a way to force SqlDependency to accept a more vague query?

Answer 1

Entity Framework core doesn't make any assumptions as to which schema you want to use. In Sql Server, usually it'll be dbo , but if you don't specify it, EF will generate schema-less SQL statements. That may cause surprises when eg you generate a database under a user that has another default schema than dbo .

Lesson I learned when working with EF core:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    // *Always* specify schema. Otherwise EF will generate schema-less DDL + DML.
    modelBuilder.HasDefaultSchema("dbo");
    ...

This will probably be enough for you. Yo can also specify the schema per table .
