    在CMD 窗口敲入exp help=y  即可看到所有的EXP参数。 Imp命令也一样。如果提示错误的话，就得确定系统环境变量中的PATH 参数有没有指向你的ORACLE安装目录下的 BIN目录。
    Export/Import有三个级别: 表级, 用户级和全数据库级.
    1. 一个导出整库的命令( 系统管理员的权限):
     exp user/password@database full=y file=full_Lot2.dmp log=expLog.txt
  2. 一个borderj用户下的数据:
     exp user/password@database owner=borderj file=borderj_Lot2.dmp log=expLog.txt

导入文件基本相同,建议在导入导出时通过脚本在做并出个log文件.

常用技巧:
  1. 把数据库对象从一个用户移到另一个用户

      Oracle 不允许直接改变表的拥有者, 利用Export/Import可以达到这一目的.

      假设要把表 T 的拥有者User1改为User2,  具体步骤是:

         - exp system/manager tables = User1.T

         - imp system/manager fromuser = User1 touser = User2 tables = T

         - drop table User1.T

         - 把数据库对象从一个表空间移到另一个表空间

    2.  建表时可以指定表空间, 表空间一经确定就部能随意改变. 若要表 T 从表空间 tbs1移到表空间 tbs2, 就要采用以下方法:

         - exp <user/passwd> tables = T

         - imp <user/passwd> tables = T indexfile =  temp.sql

         - drop table T

         - 编辑 temp.sql 只保留所需的建表命令并指定表空间为tbs2

         - 以表的所有者执行temp.sql

         - imp <user/passwd> tables = T ignore = Y

     3. 只输出一个的表空间

      通常数据库设计成用户若属于某个表空间, 那么这个用户创建的数据库对象也在该表空间内.

   Export某个表空间可用如下方法:

         a. 查看表空间内所有用户

             spool owners
          
             select owner

             from dba_segments

             where tablespace_name = '<TablespaceName>';
          

            spool off

            
         b. 查看表空间内所有数据库对象

             spool objects

             select owner, object_name, object_type

             from  dba_objects

             where owner = 'owner1'

             or   owner = 'owner2'

                  ...

             or   owner = 'ownern';

             spool off

    默认Blogger Beta blog页面顶端有搜索条, 看看起来有些不舒服,要是想吧他去掉,就在编辑HTML时将以下代码放到<b:skin></b:skin>位置
的中间:

#navbar-iframe {

visibility: hidden;
display: none;

    近来做vb.net+asp.net的项目,对于已经熟悉了Java开发平台的我来说是一种挑战,今天刚好做了有关String处理的东东,先记下来为以后参考.

String Functions

Several built-in string functions perform string manipulations to augment simple concatenation with the "&" operator. These functions are summarized in the following table.

Function	Use
Asc()	Returns the character code of the first character of a string. Asc("A") returns 65.
Chr()	Returns the display character of a character code. Chr(65) returns "A".
GetChar()	Returns the character at a specified position in a string, counting from 1. GetChar("This is a string", 7) returns "s".
InStr()	Returns the starting position in a string of a substring, counting from 1. InStr("This is a string", "string") returns 11.
InStrRev()	Returns the starting position in a string of a substring, searching from the end of the string. InStr("This is a string", "string") returns 11.
LCase()	Returns the lower-case conversion of a string. LCase("THIS IS A STRING") returns "this is a string".
Left()	Returns the left-most specified number of characters of a string. Left("This is a string", 4) returns "This".
Len()	Returns the length of a string. Len("This is a string") returns 16.
LTrim()	Removes any leading spaces from a string. LTrim("   This is a string") returns "This is a string".
Mid()	Returns a substring from a string, specified as the starting position (counting from 1) and the number of characters. Mid("This is a string", 6, 4) returns "is a".
Replace()	Replaces all occurences of a substring in a string. Replace("This is a string", " s", " longer s") returns "This are a longer string" (replaces an "s" preceded by a blank space).
Right()	Returns the right-most specified number of characters of a string. Right("This is a string", 6) returns "string".
RTrim()	Removes any trailing spaces from a string. RTrim("This is a string   ") returns "This is a string".
Str()	Returns the string equivalent of a number. Str(100) returns "100".
Space()	Fills a string with a given number of spaces. "This" & Space(5) & "string" returns "This     string".
StrComp()	Compares two strings. Return values are 0 (strings are equal), 1 (first string has the greater value), or -1 (second string has the greater value) based on sorting sequence. StrComp("This is a string", "This string") returns -1.
StrReverse()	Reverses the characters in a string. StrReverse("This is a string") returns "gnirts a si sihT".
Trim()	Removes any leading and trailing spaces from a string. Trim("   This is a string   ") returns "This is a string".
UCase()	Returns the upper-case conversion of a string. UCase("This is a string") returns "THIS IS A STRING".
Val()	Converts a numeric expression to a number. Val( (1 + 2 + 3)^2 ) returns 36.
