sqlite insert into table select * from

Question

I need to move data from one table to another in my Android app

I would like to use the following sql:

insert into MYTABLE2 select id, STATUS rispos         


        

Answer 1

explicitly specify the column name in the INSERT clause,

INSERT INTO destinationTable (risposta, data_ins)
SELECT STATUS risposta, DATETIME('now') data_ins 
FROM   sourceTable

Answer 2

You can specify which columns you're inserting into. Assuming that the _id column is autoincrement and you're inserting the other two columns, you can have something like this:

insert into MYTABLE2 (riposta, data_ins)
select STATUS risposta, DATETIME('now') data_ins from  MYTABLE 2

Answer 3

This might help, a query from one table to another and it will also check if the selected column (id) already exist in another table.

SQLite QUERY:

INSERT INTO MYTABLE2(id,data_ins ) 
SELECT id, data_ins FROM MYTABLE2
WHERE id NOT IN ( SELECT id FROM MYTABLE1)

Android:

 String select_insert_query = "INSERT INTO " + TABLE_MYTABLE2
            + "( " + ID + "," + DATA_INS + ") SELECT "
            + ID + ","
            + DATA_INS + " FROM "
            + TABLE_MYTABLE2
            + " WHERE " + ID + " NOT IN (SELECT " + ID
            + " FROM " + TABLE_MYTABLE1 + ")";

    SQLiteDatabase db = this.getWritableDatabase();

    Cursor cursor = db.rawQuery(select_insert_query, null);
    cursor.close();
