Question

我一直得到这个“表没有列名称”的错误，我在这里看到了一些解决方案，但没有一个对我有帮助。我确实看到我应该去设置/应用程序并清除数据，但我无法在设置中找到它，所以我希望我能在这里找到答案。

package com.bengu.bvb;
import android.content.ContentValues;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;
import static com.bengu.bvb.TableData.*;

public class  DataBaseOperation extends SQLiteOpenHelper {
public static final int database_version=1;
public String CREATE_QUERY="CREATE TABLE "+ TableInfo.TABLE_NAME+"("+TableInfo.PLAYER_NAME+" TEXT,"+ TableInfo.PLAYER_Family+" TEXT);";
public DataBaseOperation(Context context) {
    super(context, TableInfo.DATABASE_NAME, null, database_version);
    Log.d("Database operations","Database created");
}

@Override
public void onCreate(SQLiteDatabase sdb) {
    sdb.execSQL(CREATE_QUERY);
    Log.d("Database operations", "Table created");
}

@Override
public void onUpgrade(SQLiteDatabase arg0, int arg1, int arg2) {

}
public void putInformation(DataBaseOperation dop,String name,String family)
{
    SQLiteDatabase SQ =dop.getWritableDatabase();
    ContentValues cv=new ContentValues();

    cv.put(TableInfo.PLAYER_Family, family);
    long k= SQ.insert(TableInfo.TABLE_NAME, null,cv);
    Log.d("Database operations", "One raw inserted");

}


package com.bengu.bvb;

public class TableData {
public TableData()
{

}
public static abstract class TableInfo implements BaseColumns
{
    public static final String  PLAYER_NAME="player_name";
    public static final String  PLAYER_Family="last_name";
    public static final String  DATABASE_NAME="player_info";
    public static final String  TABLE_NAME="reg_info";
}

现在我没有得到这个错误我得到另一个错误。

Answer 1

您缺少_id列。变化

 "CREATE TABLE "+ TableInfo.TABLE_NAME+"("+TableInfo.PLAYER_NAME+" TEXT,"+ TableInfo.PLAYER_Family+" TEXT);";

到

 "CREATE TABLE "+ TableInfo.TABLE_NAME+"(_id INTEGER PRIMARY KEY AUTOINCREMENT, "+TableInfo.PLAYER_NAME+" TEXT,"+ TableInfo.PLAYER_Family+" TEXT);";

表没有列名
