10-05 17:40:09.650:上0x8b2d440準備「CREATE TABLE MYTABLE(_id INTEGER PRIMARY時,名稱的文本不爲空E /數據庫(1595):1失敗(語法錯誤附近 「」) ,設計文本不爲空,工資文本不爲空,連接文本不爲空,付款文本不爲空)'。
package example.servant;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;
public class datahandler extends SQLiteOpenHelper {
public static final String KEY_ID="_id";
public static final String KEY_NAME="name";
public static final String KEY_DESIG="desig";
public static final String KEY_SALARY="salary";
public static final String KEY_DPAY="dpay";
public static final String KEY_JOIN="join";
public static final String DATABASE_NAME="servantrecord.sqlite";
public static final String TABLE_NAME="mytable";
public static final String TAG="datahandler";
public static final int DATABASE_VERSION=1;
public static final String DATABASE_CREATE=("CREATE TABLE " + TABLE_NAME + " (" + KEY_ID
+ " INTEGER PRIMARY, " + KEY_NAME + " text not null, "
+ KEY_DESIG + " text not null, " + KEY_SALARY + " text not null, "
+ KEY_JOIN + " text not null, " + KEY_DPAY + " text not null)");
public datahandler(Context context){
super(context, DATABASE_NAME, null, DATABASE_VERSION);
Log.d("datahandler", "Database created");
}
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(DATABASE_CREATE);
Log.d("datahandler", "table created");
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
onCreate(db);
}
}
