Oracle 23ai 表和视图的列最多支持到4096个

根据经验,oracle在以前常用版本中(包含oracle 19c),表和视图支持最大的列数量为1000,在oracle 23ai中允许支持最大列数量为4096,具体参见:23ai New Feature – Increased RDBMS Table/View Column Limit to 4096 (Doc ID 2947033.1),这里做了简单的试验,确认如果要支持4096列,需要设置max_columns=’EXTENDED’
准备测试表1000列、4096列和4097列

create table t_xff_col_1000(
col1 number,
col2 number,
col3 number,
col4 number,
……
col1000 number
);


create table t_xff_col_4096(
col1 number,
col2 number,
col3 number,
col4 number,
……
col4096 number
);

create table t_xff_col_4097(
col1 number,
col2 number,
col3 number,
col4 number,
……
col4097 number
);

[oracle@xifenfei ~]$ cat tab_col_4096.sql |grep col|grep -v xff|wc -l
4096
[oracle@xifenfei ~]$ cat tab_col_1000.sql |grep col|grep -v xff|wc -l
1000
[oracle@xifenfei ~]$ cat tab_col_4097.sql |grep col|grep -v xff|wc -l
4097

在max_columns为默认值的情况下(STANDARD)23ai版本中最多也只能支持1000列

ORA-19815: ??: db_recovery_file_dest_size ?? (? 10737418240 ??) ??? 100.00%, ?? 0 ?????
************************************************************************
You have following choices to free up space from recovery area:
1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,
   then consider changing RMAN ARCHIVELOG DELETION POLICY.
2. Back up files to tertiary device such as tape using RMAN
   BACKUP RECOVERY AREA command.
3. Add disk space and increase db_recovery_file_dest_size parameter to
   reflect the new space.
4. Delete unnecessary files using RMAN DELETE command. If an operating
   system command was used to delete files, then use RMAN CROSSCHECK and
   DELETE EXPIRED commands.

是由于闪回区满了,导致redo无法归档,从而使得数据库无法正常open,解决办法:
1. 清理以前归档日志
2. 把闪回区调大一些
