sqlite 数据库开发中一些用法

sqlite 可以允许把各种类型的数据保存到任何字段中，不用关心数据库本身字段声明的数据类型是什么

1.分页

select * from Account limit 1 offset 10select * from Account limit 5 offset 15  

1. TRIM REPLACE 函数

/**     * x'0A' represents the '\n' character in sqlite. For title and content in     * the search result, we will trim '\n' and white space in order to show     * more information.     */private static final String AAAAA = NoteColumns.ID + " AS " + SearchManager.SUGGEST_COLUMN_INTENT_EXTRA_DATA + ","            + "TRIM(REPLACE(" + NoteColumns.SNIPPET + ", x'0A','')) AS "            + SearchManager.SUGGEST_COLUMN_TEXT_1 + ","            + "TRIM(REPLACE(" + NoteColumns.SNIPPET + ", x'0A','')) AS "            + SearchManager.SUGGEST_COLUMN_TEXT_2 + ","            + R.drawable.search_result + " AS " + SearchManager.SUGGEST_COLUMN_ICON_1 + ","            + "'" + Intent.ACTION_VIEW + "' AS " + SearchManager.SUGGEST_COLUMN_INTENT_ACTION + ","            + "'" + NoteConstant.TextNote.CONTENT_TYPE + "' AS "            + SearchManager.SUGGEST_COLUMN_INTENT_DATA;
