lightdb UPDATE INDEXES自动分区转换支持全大写索引名

背景

普通表转分区表，Oracle中的写法习惯索引名会使用大写并用双引号包起来。这导致LightDB 在匹配索引名时提示索引名不存在。

LightDB 23.3.02增量版本对此进行了支持。

示例

准备环境

create database test_oracle with lightdb_syntax_compatible_type  oracle;
\c test_oracle

创建一张普通表

create table tb_list1
(city_id integer not null,city_name varchar2(30) not null,city_state varchar2(20) not null,city_amount integer not null
);

创建索引

create index TB_LIST_I01 on tb_list1(city_amount);
create index TB_LIST_I02 on tb_list1(city_name);

将普通表转为分区表

alter table tb_list1 MODIFY partition by range(city_amount)(partition tb_list1_amount1 values less than (101),partition tb_list1_amount2 values less than (105)) ONLINE UPDATE INDEXES("TB_LIST_I01" global,"TB_LIST_I02" local);

在LightDB 23.03.02之前的版本会提示索引找不到，原因是创建索引时没有带引号，而ALTER时携带了引号。
