SQLite Query in non case sensitive alphabetical order

How to use SQL Order By statement to sort results case insensitive? 3 answers

COLLATE goes before the order direction:

db.rawQuery("SELECT " + catName 
           + " FROM " +tableName 
        +" ORDER BY "+catName+" COLLATE NOCASE ASC;", null);

But you don't need the ASC -- that's the default so you could just as well use:

db.rawQuery("SELECT "+ catName 
            +" FROM "+ tableName 
        +" ORDER BY "+ catName +" COLLATE NOCASE;", null);

add COLLATE NOCASE after orderBy String.

db.query(table, columns, selection, selectionArgs, groupBy, having, orderBy + " COLLATE NOCASE ASC");

here, order by ASC or DESC depends on your need.

这应该也适用我认为：

db.rawQuery("SELECT "+ catName 
        +" FROM "+ tableName 
    +" ORDER BY lower("+ catName +");", null);
