SQL Error: ORA-00906: missing left parenthesis 00906. 00000 - "missing left parenthesis"
提问by Jatinder Singh
CREATE TABLE customer(customer_id NUMBER(6) PRIMARY KEY
, customer_name VARCHAR2(40) NOT NULL
, customer_address VARCHAR2(60) NOT NULL
, customer_email VARCHAR2(35)
, customer_number NUMBER (11) NOT NULL CHECK LENGTH(customer_number) = 11)
This is just taking the mick I don't understand what is wrong
这只是拿麦克风我不明白有什么问题

You're not specifying a constraint name, and I believe that you need to have the check constraint in brackets:
您没有指定约束名称，我相信您需要在括号中包含检查约束：
, customer_number NUMBER (11) NOT NULL
constraint custnumlen CHECK (LENGTH(customer_number) = 11))
