单击插入按钮

时发生以下错误

CustomOpenHelper.java

public class CustomOpenHelper extends SQLiteOpenHelper{

public static final String TABLE_NAME = "players";
public static final String COLUMN_ID = "_id";
public static final String COLUMN_NAME = "name";
public static final String COLUMN_SCORE = "score";

private static final String DATABASE_CREATE = "create table" + TABLE_NAME
        + "(" + COLUMN_ID + "integer primary key autoincrement,"
        + COLUMN_NAME +"text not null,"
        + COLUMN_SCORE +"integer not null);";


public CustomOpenHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version) {
    super(context, name, factory, version);
}

@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL(DATABASE_CREATE);
}

logcat的

android.database.sqlite.SQLiteException：靠近“tableplayers”：语法错误（代码1）:,同时编译：create tableplayers（_idinteger主键autoincrement，nametext not null，scoreinteger not null）;

如何解决这个问题？

Answer 1

您需要在创建命令中的table和TABLE_NAME之间提供一个空格（＆＃39;＆＃39;）。

private static final String DATABASE_CREATE = "create table " + TABLE_NAME
        + "(" + COLUMN_ID + " integer primary key autoincrement,"
        + COLUMN_NAME +" text not null,"
        + COLUMN_SCORE +" integer not null);";

注意"create table "中每个column的数据类型之前的空间。

Answer 2

尝试使用创建表格（如果不存在）而不是创建表格。并且还在create table和＆＃34;之间留出空间（＆＃34;。修改后的查询应该看起来像

private static final String DATABASE_CREATE = "create table if not exists " + TABLE_NAME
        + " (" + COLUMN_ID + " integer primary key autoincrement,"
        + COLUMN_NAME +" text not null,"
        + COLUMN_SCORE +" integer not null);";

android.database.sqlite.SQLiteException：靠近“tableplayers”：语法错误（代码1）
