在使用 Oracle 的 OFFSET FETCH 子句进行分页查询时,并不要求必须排序。OFFSET FETCH 子句允许您从结果集中选择一定数量的行,并且可以通过指定 OFFSET(偏移量)和 FETCH(获取数量)参数来实现分页效果。 以下是使用 OFFSET FETCH 子句进行简单分页查询的示例: SELECT column1, column2, ... FROM table_name ORDER BY...
可以通过FETCH FIRST/NEXT关键字指定返回结果的行数 可以通过PERCENT关键字指定返回结果的行数比例 可以通过OFFSET关键字指定返回从结果集中的某一行之后行数 12c row-limiting子句对于排序数据限制返回行今后会广泛使用(MySQL上早就有的特性,MySQL开发该特性可能是特别考虑到对于网站分页查询的简化),也可以被称作Top-N查...
FETCH FIRST 10 PERCENT ROWS ONLY; 以下示例忽略前5条记录并会显示表的下5条记录: SQL> SELECT eno,ename,sal FROM emp ORDER BY SAL DESC OFFSET 5 ROWS FETCH NEXT 5 ROWS ONLY; 所有这些限制同样可以很好的应用于PL/SQL块。 复制 BEGINSELECTsal BULK COLLECTINTOsal_vFROMEMPFETCHFIRST100ROWSONLY;END;...

The old behavior was to construct aTimestampthat would print the same value as the database value. But sinceTimestampis in the UTC time zone this would give aTimestampvalue that was offset from the correct value. 8:00am January 1, 2007 UTC is not the same as 8:00am January 1, 2007...
