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 10

select * 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 + ",'')) 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;
