The list of columns to put into the cursor. If null all columns are included.

selection

A selection criteria to apply when filtering rows. If null then all rows are included.

selectionArgs

You may include ?s in selection, which will be replaced by the values from selectionArgs, in order that they appear in the selection. The values will be bound as Strings.

sortOrder
