oracle常见的异常

经常遇到一些java.sql.SQLException异常，从网上汇集一些前人的资料，以供以后调试查阅！


ORA-00904:  invalid column name 无效列名
ORA-00942:  table or view does not exist 表或者视图不存在
ORA-01400:  cannot insert NULL into () 不能将空值插入
ORA-00936:　缺少表达式
ORA-00933:　SQL 命令未正确结束
ORA-01722:　无效数字：（一般可能是企图将字符串类型的值填入数字型而造成）
ORA-06530:  ACCESS_INTO_NULL　
      Your program attempts to assign values to the attributes of an uninitialized (atomically  null) object.
企图将值写入未初化对象的属性


ORA-06592:  CASE_NOT_FOUND
     None of th  choice  in the WHEN clauses of a CASE statement is selected,  and there is no  ELSE clause.
case语句格式有误，没有分支语句


ORA-06531:  COLLECTION_IS_NULL
     Your program attempts to apply collection methods othe  than EXIST  to an uninitialized(atomically  null) nested table or varray, or th  program attempts to assign values to the elements of an  uninitialized nested table  or  varray.
企图将集合填入未初始化的嵌套表中


ORA-06511:  CURSOR_ALREADY_OPEN
     Your program attempts to open an already open cursor. A cursor must be closed before it can  be reopened.  A cursor FOR loop automatically opens the cursor to which it refers. So, your  program cannot open that cursor inside  the  loop.
企图打开已经打开的指针．指针已经打开，要再次打开必须先关闭．


ORA-00001:  DUP_VAL_ON_INDEX
     Your program attempts to store duplicate values in a database column that is constrained by  a unique index.
数据库字段存储重复，主键唯一值冲突


ORA-01001:  INVALID_CURSOR　无效指针
    Your program attempts an illegal cursor operation such as closing an unopened cursor.
非法指针操作，例如关闭未打开的指针


ORA-01722:  INVALID_NUMBER　无效数字
     In a SQL statement, the conversion of a character string into a number fails because the  string does not represent a valid number. (In  procedural statements, VALUE_ERROR is raised.) This exception is also raised when the LIMIT-clause expression in a bulk FETCH  statement does not evaluate to a positive number.
在sql语句中，字符数字类型转换错误，无法将字符串转化成有效数字．此错误也可能因为在limit从句表达式中fetch语句无法对应指定数字


ORA-01017:  LOGIN_DENIED　拒绝访问
     Your program attempts to log on to Oracle with an invalid username and/or password.
企图用无效的用户名或密码登录oracle


ORA-01403:  NO_DATA_FOUND  无数据发现
     A SELECT INTO statement returns no rows, or your program references a deleted element in a  nested table  or an  uninitialized  element  in  an  index-by  table.  SQL  aggregate  functions  such  as  AVG  and  SUM  always  return  a value or a null.  So, a SELECT INTO statement that calls an aggregate function  never  raises  NO_DATA_FOUND. The FETCH statement is  expected to return no rows eventually, so when that happens, no exception is raised.
  
ORA-01012:  NOT_LOGGED_ON   未登录
     Your program issues  a database call without being connected to Oracle.
程序发送数据库命令，但未与oracle建立连接
  
ORA-06501:  PROGRAM_ERROR  程序错误
     PL/SQL  has  an  internal  problem.
pl/sql系统问题
  
ORA-06504:  ROWTYPE_MISMATCH  行类型不匹配
    The  host  cursor  variable  and  PL/SQL  cursor  variable  involved  in  an  assignment  have  incompatible  return  types. 
For example, when an open host cursor variable is passed to a stored  subprogram, the return types of the actual and formal parameters must be compatible. 
  
ORA-30625:  SELF_IS_NULL  
     Your  program  attempts  to  call  a  MEMBER  method  on  a  null  instance.  That  is,  the  built-in  parameter  SELF (which  is  always  the  first  parameter  passed  to  a  MEMBER  method)  is  null.
  
ORA-06500:  STORAGE_ERROR  存储错误
     PL/SQL runs out of memory  or memory has been corrupted.
PL/SQL运行内存溢出或内存冲突
      
ORA-06533:  SUBSCRIPT_BEYOND_COUNT   子句超出数量
      Your program references a nested table or varray element using an index number larger than the number of elements in  the collection.
  
ORA-06532:  SUBSCRIPT_OUTSIDE_LIMIT   子句非法数量
Your program references a nested table or varray element using an index number (-1  for  example)  that  is outside  the  legal  range.
  
ORA-01410:  SYS_INVALID_ROWID   无效的字段名
   The conversion  of  a  character  string  into  a  universal  rowid  fails  because  the  character  string  does  not represent  a  valid  rowid. 
  
ORA-00051:  TIMEOUT_ON_RESOURCE    资源等待超时
A time-out occurs while Oracle is waiting for a resource. 
  
ORA-01422:  TOO_MANY_ROWS    返回超过一行
A SELECT INTO statement returns more  han one row.
  
ORA-06502:  VALUE_ERROR   值错误
An arithmetic, conversion, truncation, or size-constraint error occurs. For example, when  your program selects a column value into a character  variable, if the value is  longer  than  the  declared  length  of  the  variable, PL/SQL aborts the assignment and raises VALUE_ERROR.  In procedural statements,  VALUE_ERROR  is raised if the conversion of a character string into a number fails.  (In SQL statements, INVALID_NUMBER is raised.) 
  
ORA-01476:  ZERO_DIVIDE  除0错误
Your program attempts to divide a number by zero.
