Question

From the doc:

http://developer.android.com/reference/android/database/DatabaseUtils.InsertHelper.html

What does this line means?

but compile the SQL insert statement only once,

Please explain, i am not able to understand this.

Regards,

Answer 1

if you do

SQLiteDatabase db = getDatabaseFromSomewhere();

db.insert("tableName", null, contentValues1);
db.insert("tableName", null, contentValues2);
db.insert("tableName", null, contentValues3);

each time you call insert Android will create a new SQLiteStatement. If you do the same with an InsertHelper it creates only 1 statement and reuses that which may be faster.
