SQL常见的可优化点
# ###########################################
# 索引相关
# ###########################################
– 查询（或更新，删除，可以转换为查询）没有用到索引
这是最基础的步骤，需要对sql执行explain查看执行计划中是否用到了索引，需要重点关注type=ALL, key=NULL的字段。
– 在索引字段上施加函数
to_char(gmt_created, ‘mmdd’) = ’0101′
正确的写法
gmt_created between to_date(“20090101″, “yyyymmdd”) and to_date(“20090102″, “yyyymmdd”)
– 在索引字段上使用全模糊
