The equivalent is a bit field.

(等价物是一个位域。)

In SQL you use 0 and 1 to set a bit field (just as a yes/no field in Access).

(在SQL中,您使用0和1来设置位字段(就像Access中的是/否字段一样)。)

In Management Studio it displays as a false/true value (at least in recent versions).

(在Management Studio中,它显示为false / true值(至少在最近的版本中)。)

When accessing the database through ASP.NET it will expose the field as a boolean value.

(通过ASP.NET访问数据库时,它会将该字段公开为布尔值。)
