Question

请检查我的语法和指正。通过

我得到错误 引起：android.database.sqlite.SQLiteException：近“BETWEEN30”：语法错误（代码1 ）：在编译：SELECT * FROM TABLE_ITEMS WHERE日期BETWEEN30/06/2017'AND'07/07/2017'

String query = " SELECT * FROM " + TABLE + " WHERE date BETWEEN" + past_date + "'AND'" + current_date + "' " ; 

Answer 1

一个SQLite例外，指示不存在与SQL解析 或执行错误。

使用BLANK SPACE & Single-Double字整顿你的声明。

String query = " SELECT * FROM " + TABLE_ITEMS + " WHERE date BETWEEN " + past_date + " AND " + current_date + " ; 

您可以

"SELECT * FROM " + TABLE_NAME+ " WHERE date "+ BETWEEN past_date('"+DATE_STR_FORMAT+"') + " AND current_date " ('"+DATE_STR_FORMAT_CURRENT+"')"";
