添加外键时Sqlite查询中的语法错误

Question

执行查询时，我的sqlite查询中出现语法错误

  db.execSQL("CREATE TABLE "+TABLE_ABC+" (ID INTEGER PRIMARY KEY AUTOINCREMENT, EVENT_MATCH_ID INTEGER, FOREIGN KEY (EVENT_MATCH_ID) REFERENCES "+TABLE_DEF+" (MATCH_ID), EVENT_ID TEXT, EVENT_TYPE TEXT, EVENT_MINUTE TEXT," +
                        "EVENT_TEAM TEXT, EVENT_PLAYER TEXT, EVENT_PLAYER_ID TEXT, EVENT_RESULT TEXT)");

错误是“ EVENT_ID附近的语法错误”。 有人可以帮助我追踪错误吗？

Answer 1

将表约束（例如外键定义）放在列规范之后：

db.execSQL("CREATE TABLE "+TABLE_ABC+" (ID INTEGER PRIMARY KEY AUTOINCREMENT, EVENT_MATCH_ID INTEGER, EVENT_ID TEXT, EVENT_TYPE TEXT, EVENT_MINUTE TEXT," +
                    "EVENT_TEAM TEXT, EVENT_PLAYER TEXT, EVENT_PLAYER_ID TEXT, EVENT_RESULT TEXT, " +
                    "FOREIGN KEY (EVENT_MATCH_ID) REFERENCES "+TABLE_DEF+" (MATCH_ID))");

Answer 2

表约束位于列定义之后： https : //www.sqlite.org/lang_createtable.html

尝试这个：

db.execSQL("CREATE TABLE "+TABLE_ABC+" (ID INTEGER PRIMARY KEY AUTOINCREMENT, EVENT_MATCH_ID INTEGER, EVENT_ID TEXT, EVENT_TYPE TEXT, EVENT_MINUTE TEXT," +
                "EVENT_TEAM TEXT, EVENT_PLAYER TEXT, EVENT_PLAYER_ID TEXT, EVENT_RESULT TEXT, " +
                "FOREIGN KEY (EVENT_MATCH_ID) REFERENCES "+TABLE_DEF+" (MATCH_ID))");

请尝试以下操作：

db.execSQL("CREATE TABLE "+TABLE_ABC+" (ID INTEGER PRIMARY KEY AUTOINCREMENT, EVENT_MATCH_ID INTEGER, EVENT_ID TEXT, EVENT_TYPE TEXT, EVENT_MINUTE TEXT," +
                    "EVENT_TEAM TEXT, EVENT_PLAYER TEXT, EVENT_PLAYER_ID TEXT, EVENT_RESULT TEXT, FOREIGN KEY (EVENT_MATCH_ID) REFERENCES "+TABLE_DEF+" (MATCH_ID))");
