java ejb开发 程序4、语句alter table people add(phone_number varchar2(10)) 的作用是 A 修改表结构 B 为people表添加约束，约束名称是phone_number C 向people表中添加一列，名称是phone_number，数据类型是varchar2，长度是10 D 上述答案均不正确 5、（ ）BLOB和CLOB的区别在于 A CLOB只能存放字符类型的数据，而BLOB没有任何限制 B BLOB只能存放字符类型的数据，而CLOB没有任何限制 C CLOB只能存放小于4000字节的数据，而BLOB可以存放大于4000字节的数据 D BLOB只能存放小于4000字节的数据，而CLOB可以存放大于4000字节的数据 6、存储过程从本质上来讲就是 A 匿名的PL/SQL程序块，它可以被赋予参数 B 命名的PL/SQL程序块，它可以被赋予参数 C 命名的PL/SQL程序块，不能被赋予参数 D 匿名的PL/SQL程序块，不能被赋予参数 7、（ ）下列关于日期数据类型，哪一个语句是正确的写法 A insert into test values( 9999-12-03 ) B insert into test values( 1999-03-02 ) C insert into test values(to_char(1999-06-03, yyyy/dd/mm )) D insert into test-four development process, the statement alter table people add (phone_number varchar2 (10)) is the role of Table A revised structure for the people Table B added constraint, constraint name of the people phone_number Table C to add a name is phone_number. yes varchar2 data type, length is the answer above 10 D falsities 5, () BLOB and CLOB the difference is only a CLOB type of characters stored data, and BLOB no restrictions placed only B BLOB data type characters, and CLOB no restrictions only C CLOB deposit of less than 4000 bytes of data, and BLOB can be stored more than 4,000 gigabytes of data storage D BLOB only less than 4000 bytes of data, and CLOB can be stored more than 4,000 gigabytes of data on six, and stored in essence, it was A anonymous PL / SQL block, it can be given the pa
