SQLite-将LIKE子句与AND子句一起使用

Question

So I needed to search through a TABLE in my Database.

I created a SQLite Query like so

String selection = COLUMN_1 + " LIKE ? AND " + COLUMN_2 + " ?= AND " + COLUMN_3 + " ?=";
String selectionArgs[] = {"%" + value1 + "%", value2 , value3 };

Cursor cursor = db.query(TABLE_1, null, selection, selectionArgs, null, null, null);

I got the following error

SQLiteException: near "?": syntax error (Sqlite code 1): , while compiling: SELECT * FROM TABLE_1 WHERE COLUMN_1 LIKE ? AND COLUMN_2 ?= AND COLUMN_3 ?=, (OS error - 2:No such file or directory)

After trying many different variations and research I gave up and wrote a rawQuery

String query = "SELECT * FROM " + ITEMS_CONTENT_TABLE + " WHERE " + ITEM_NAME + " LIKE '%" + name + "%' AND " + BASE_CATEGORY_NAME + " = '" + baseCategoryName + "' AND " + BASE_CATEGORY_SRC_PATH + " = '" + baseCategorySrcPath + "';";

Cursor cursor = db.rawQuery(query , null);

Which worked seamlessly!

My question is why is the former not working? If it really was syntax error then it shouldn't be working in the later example either.

Answer 1

如下更改查询

String selection = COLUMN_1 + " LIKE ? AND " + COLUMN_2 + " =? AND " + COLUMN_3 + " =?"

Answer 2

下面的查询在我的情况下工作正常。

 Cursor c = db.rawQuery("Select ConsAcNo From FieldUtilityData Where ConsAcNo like '%" + txtConsAcNo.getText() + "%' and ProjectNo = '" + gp.city + "' and IsCompleted = 'N' and ConsAcNo not in (SELECT CONS_ACCOUNT_NO FROM FieldTestDataFinal) Limit 15", null);
