創建前可先刪除

drop table tmp0

創建臨時表

select * into temp table tmp0 from xxx create index idx_tmp0_inner_cd on tmp0(inner_cd);

查看臨時表是否創建，返回0表示未創建，1為創建

select count(*) from pg_class where relname = ‘tmp0’　

或者用下面，下面語句在pg和mysql中都適用

Create Table If Not Exists temp.MyTable(
xxx varchar (20) Primary key ,
thTime varchar (20) ,
name varchar (20)
)
