I created a table in oracle10g using following query……

  CREATE TABLE  "EMPLOYEESTASKS" 
  ( "EMPLOYEEID" NUMBER, 
"TASKDATE" VARCHAR2(40), 
"STATUS" NUMBER, 
"CUSTOMERID" NUMBER, 
"ADDRESS" VARCHAR2(400) NOT NULL ENABLE, 
"TASKTIME" VARCHAR2(40) NOT NULL ENABLE, 
"VISITDATE" VARCHAR2(40), 
"VISITTIME" VARCHAR2(40), 
 CONSTRAINT "EMPLOYEESTASKS_PK" PRIMARY KEY ("EMPLOYEEID", "TASKDATE", "TASKTIME") ENABLE, 
 CONSTRAINT "EMPLOYEESTASKS_FK" FOREIGN KEY ("EMPLOYEEID")
  REFERENCES  "EMPLOYEES" ("ID") ON DELETE CASCADE ENABLE
 )

Table was created successfully… but the problem is while iam trying to insert a row into the table it is showing the error

   ORA-01722: invalid number

The query i used is ,

 insert into employeestasks values(12305,'30-11-2011','09:00',0,45602,'Sarpavaram Junction ,kakinada',null,null)

    It look like your columns in the table are ordered employeeid, taskdate, status, and you’re trying to insert ’09:00′ into status, which is a number. This is no good. You need to use the same order of columns or specify which value is for which column.

    Also, you really like capslock, huh?
