C# Oracle同时执行多条sql语句

最近经常要在程序中创建不同的表

create table TableName
(
Id NUMBER not null,
Age NUMBER not null,
Name NVARCHAR2(50)

);

comment on column TableName.Id is
'comment';

comment on column TableName.Name is
'comment';

comment on column TableName.Age is
'comment';


执行时会报错 ORA-00911: 无效字符 加上BEGIN END 也还是报错
BEGIN
EXECUTE IMMEDIATE
'create table TableName
(
Id NUMBER not null,
Age NUMBER not null,
Name NVARCHAR2(50)

)';

EXECUTE IMMEDIATE
'comment on column TableName.Id is
''comment''';
EXECUTE IMMEDIATE
'comment on column TableName.Name is
''comment''';
EXECUTE IMMEDIATE
'comment on column TableName.Age is
''comment''';
END;

cmd.ExecuteNonQuery成功
