android sqlite 一次创建多个表

package com.yangguangfu.database;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;
/**
 * 默认就在数据库里创建4张表
 * 
 *
 */
public class DBOpenHelper extends SQLiteOpenHelper {
    private static final String name = "database.db";//数据库名称
    private static final int version = 1;//数据库版本

    public DBOpenHelper(Context context) {
        super(context, name, null, version);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        Log.e("DBOpenHelper", "DBOpenHelperDBOpenHelperDBOpenHelperDBOpenHelper");
        db.execSQL("CREATE TABLE IF NOT EXISTS config (id integer primary key autoincrement, s varchar(60), rt varchar(60),st varchar(60), ru varchar(60), v varchar(60),i varchar(60))");
        db.execSQL("CREATE TABLE IF NOT EXISTS application (id integer primary key autoincrement, s varchar(60), tt varchar(60),st varchar(60),tc1 varchar(60), tc2 varchar(60), ru varchar(60),tn varchar(60),m varchar(60))");
