标签:rom color from acl str select 1.4 style count
跟oracle中的instr用法一样:
SQL> select count(*) from t where instr(title,?oracle?)>0; COUNT(*) ———- 5478
Elapsed: 00:00:11.04
SQL> select count(*) from t where title like ”%oracle%?; COUNT(*) ———- 5478
Elapsed: 00:00:31.47
注:
instr(title,‘oracle?)>0 相当于like
instr(title,‘oracle?)=0 相当于not like
