大家好，又见面了，我是全栈君。
有时候我们能够将类似省份城市的数据库文件存放在assets/目录名/××.sql下。当程序在创建数据库时读取该数据库文件，并运行其内的sql语句
![读取本地数据库文件[通俗易懂]](https://javaforall.net/wp-content/uploads/2020/11/2020110817443450.jpg)
在SqLiteOpenHelper类的onCreate方法中调用 executeAssetsSQL(db, “××.sql”);
/**
* 读取数据库文件（.sql）。并运行sql语句
* */
private void executeAssetsSQL(SQLiteDatabase db, String schemaName)
{
BufferedReader in = null;
try
{
in = new BufferedReader(new InputStreamReader(AppApplication
.getIns().getAssets().open("aiyeqiaodb/" + schemaName)));
System.out.println("路径:aiyeqiaodb/" + schemaName);
String line;
String buffer = "";
while ((line = in.readLine()) != null)
{
buffer += line;
if (line.trim().endsWith(";"))
{
db.execSQL(buffer.replace(";", ""));
buffer = "";
}
}
}
catch (IOException e)
{
LogUtil.i("db-error" + e.toString());
}
finally
{
try
{
if (in != null)
in.close();
}
catch (IOException e)
{
LogUtil.i("db-error" + e.toString());
}
}
}
以下附上省份城市的数据库文件 ——××.sql

create table IF NOT EXISTS city_table (_id integer primary key autoincrement, city varchar(20), cityID varchar(10), father varchar(10));
