如何通过输入字母排序SQLite查询的结果？

Question

String sql = "SELECT * FROM " + TABLE_NAME +
                " WHERE " + ENGLISH + " LIKE ? ORDER BY " + ENGLISH + " LIMIT 100";

try {
            cursor = db.rawQuery(sql, new String[]{"%" + englishWord + "%"});

For example, in the column ENGLISH , there are "ice", "dice", "vice" etc. When I input the word "ice" in englishWord , I will get the result arranged firstly by "dice", followed by "ice" and "vice". But I would like "ice" to be on the first order because it has the exact word. How I can accomplish this?

Answer 1

Use LENGTH Function to get Exact Matched Phrase , This Should be your Query

String sql = "SELECT * FROM " + TABLE_NAME +
                " WHERE " + ENGLISH + " LIKE ? ORDER BY LENGTH(" + ENGLISH + ") LIMIT 100";

Answer 2

To order exact matches first, add another ORDER BY expression that returns a smaller number for exact matches:

rawQuery("... ORDER BY "+ENGLISH+" != ?, "+ENGLISH+"...",
         new String[]{ "%"+englishWord+"%", englishWord });

English != ? is a boolean expression; it returns either 0 or 1.
