Oracle SQL数据库创建大小超过4000的clob

Question

I'm trying to alter table and add a new column as a clob, but I'm only allowed to set the size to 4,000. The syntax I'm using is:

ALTER TABLE table_name
add column_name CLOB(100000)

The error I'm getting is:

ORA-01735: invalid ALTER TABLE option

If I put:

ALTER TABLE table_name
add column_name CLOB

This allows me to create a column of default size 4,000.

Answer 1

它告诉您invalid ALTER TABLE option因为它是一个无效选项 - 您无法指定clob的大小。
