Delete row in database table given one column value - which is a string

Question

I have a table with column headings: | _id (long) | Name (String) | x (integer) | y (integer) |

I want to delete the row in the table that has Name myName.

Answer 1

depending on the complexity of your where condition, the "delete" method will not be the best solution.

for example, if you want to delete all records whose "_id" is in a second table, like you would write in transactSQL: "...WHERE _id IN (SELECT _id FROM..." then the best solution might be to use the ".execSQL()" method directly on your database.

myDatabase.execSQL("DELETE FROM myTable WHERE _id IN (SELECT _id FROM myOtherTable)");

or you could go real ugly and do something like:

int cursorRows = cursor.getCount();
String[] id2String = new String[cursorRows];
String id2StringUnique = "";
//for (int i=0;i

depending on number of items, you might have a problem with the length / size of your argument - besides it being diselegant to the extreme.
