前期准备:
create table T9(A int ,B text,C text,fulltext index fix_test_for_T8_B(B));#在定义表的时候加索引
create unique index ix_test_for_T8_A on T9(A);#加朴素索引
create fulltext index fix_test_for_T8_C on T9(C);#加全文索引
------------------------------------------------------------
解决办法:
select index from table_name。
-------------------------------------------------------------------------------------------------------------------------------------------
select index from T9;
