sqlite alter table add MULTIPLE columns in a single statement

Question

Is it possible to alter table add MULTIPLE columns in a single statement in sqlite? The following would not work.

alter table test add column mycolumn1 text, add          


        

Answer 1

The answer from @mu is too short' is right. As an extra, adding an optimized workaround for adding multiple columns using the benefit of transactions in SQL.

String alterTableQuery = "ALTER TABLE " + TABLE_NAME + " ADD COLUMN ";
List newColumns = ..// Your new columns

db.beginTransaction();
for (String column : newColumns){
    db.execSQL(alterTableQuery + column +  " VARCHAR");
}
db.setTransactionSuccessful();
db.endTransaction();

I hope this will help someone.
