android - Android - save multiple record affecting multiple tables

Question

I have a project have to save some register into to database SQLite, but at the same time insert into another table.

Example:

tables : contact_enc contact_det
contact_enc columns: id, name, telefono
contact_det columns: id, id_ce, name, address, status

I need to insert into contact_enc the field and same times contact_det the field.

Answer 1

只需使用两次插入操作

Answer 2

String sql = "INSERT INTO contact_enc yourdatabase"; 
long lastID = this.database.execSQL(sql); 

int lastInsertId = Integer.ValueOf(lastId);

if(lastInsertId > 0) {
    String sql2 = "INSERT INTO contact_det (id_ce) VALUES(lastInsertId)"; 
    this.database.execSQL(sql2);
}

Answer 3

如果 的id列contact_enc定义为INTEGER PRIMARY KEY，您可以使用last_insert_rowid()函数，就像下面的 SQL 语句一样，一个接一个地执行：

BEGIN TRANSACTION;
INSERT INTO contact_enc (name, telefono) VALUES (:Name, :Telefono);
INSERT INTO contact_det (id_ce, name, address, status) SELECT last_insert_rowid(), :Name, :Address, :Status;
COMMIT;

（注意 , :Name, :Telefono, :Name,:Address和:Status是按名称绑定的参数。如果您希望按数字绑定参数，这在 Android 中似乎更容易做到，只需将每个占位符替换为 ? 问号）。
