Question

我似乎无法找到关于未创建列的原因的错误。

public static final String GAME_TABLE = "Game";

public static final String KEY_GAMEID = "_id";
public static final int COL_GAMEID = 0;

public static final String KEY_OPONENT = "opponentTeam";
public static final int COL_OPONENT = 1;

public static final String KEY_GAME_FIRST_PLAYER = "GamePLAYER1";
public static final int COL_GAME_FIRST_PLAYER = 2;

public static final String KEY_GAME_SECOND_PLAYER = "GamePLAYER2";
public static final int COL_GAME_SECOND_PLAYER = 3;

public static final String KEY_FK_GAME = "FKtournament";
public static final int COL_FK_GAME = 4;

public static final String[] ALL_GAME_KEYS = new String[] {
    KEY_GAMEID, KEY_OPONENT, KEY_GAME_FIRST_PLAYER, KEY_GAME_SECOND_PLAYER, KEY_FK_GAME};

     //THIS IS WHERE I CREATE MY TABLE
     // KEY REY_ROWID is from another table

private static final String GAME_TABLE_CREATE_SQL = 
        "create table " + GAME_TABLE 
        + " (" 
        + KEY_GAMEID + " integer primary key autoincrement, "
        + KEY_OPONENT + " string not null, "
        + KEY_GAME_FIRST_PLAYER + "string not null, "
        + KEY_GAME_SECOND_PLAYER + "string not null, "
        + KEY_FK_GAME+" INTEGER REFERENCES "+KEY_ROWID
        + ");";


public long insertGAMERow(String opponentTeam, String GamePLAYER1,  String GamePlayer2, int key) {
    ContentValues initialValues = new ContentValues();
    initialValues.put(KEY_OPONENT, opponentTeam);
    initialValues.put(KEY_GAME_FIRST_PLAYER, GamePLAYER1);
    initialValues.put(KEY_GAME_SECOND_PLAYER, GamePlayer2);
    initialValues.put(KEY_FK_GAME, key);
    return db.insert(GAME_TABLE, null, initialValues);
}

以下是错误日志：

sqlite中没有string类型，而是使用TEXT。此外，列名称及其数据类型中没有空格：

+ KEY_GAME_FIRST_PLAYER + "string not null, "// <------ error, no space in name and datatype
+ KEY_GAME_SECOND_PLAYER + "string not null, "// <------ error, //

所以结束查询就像

create table Game(_id integer primary key autoincreament, opponentTeam string not null GamePlayer1string not null ...看到问题了吗？

private static final String GAME_TABLE_CREATE_SQL = 
    "create table " + GAME_TABLE 
    + " (" 
    + KEY_GAMEID + " integer primary key autoincrement, "
    + KEY_OPONENT + " TEXT not null, "
    + KEY_GAME_FIRST_PLAYER + " TEXT not null, "
    + KEY_GAME_SECOND_PLAYER + " TEXT not null, "
    + KEY_FK_GAME+" INTEGER REFERENCES "+KEY_ROWID
    + ");";

在将数据存储到我的Sqlite时，它返回我的列未创建
