First off, using the update method is wrong. Deleting is not the same as updating. Updating in SQL means changing the value of one or more fields in a row. What you are looking for is the delete method
dbHelper.delete(TABLE_NAME, whereClause="Your actual where statement here", args)
The where statement follows a slightly different syntax than the regular where clauses in SQLite. This is an exception to the update method because it has a method for "regular" SQL through a builder. The delete method does not have this though, so you have to use the Anko syntax.
Essentially you can use this as a where clause:
"someRow = {someRowData} AND differentRow = {otherData}"
and in the arguments:
"someRowData" to "whatever value you want",
"otherData" to 1234
I'm not entirely sure whether or not the AND
keyword will work, the syntax isn't fully documented. I assume it should because there's nothing else documented. The general SQLite syntax should be valid, and only the argument replacement (to avoid SQL injection I assume) is different
