                  在 SQLITE 中指定多于 1 列的主键的语法是什么?

                  What is the syntax for specifying a primary key on more than 1 column in SQLITE ?

                  推荐答案

                  根据文档,这是

                  CREATE TABLE something (
                    column1, 
                    column2, 
                    column3, 
                    PRIMARY KEY (column1, column2)
                  );
