Looks like the way of building the insert statement is wrong, the parameter name should start with : (semicolumn) in the insert query

for example if your
string query = "select count(deptno) from dept where " _

+ "dname = :dname and loc = :loc "; // C#

OracleParameter p1 = new OracleParameter("dname", OracleDbType.Varchar2);
p1.Value = textBox1.Text;

OracleParameter p2 = new OracleParameter("loc", OracleDbType.Varchar2);
p2.Direction = ParameterDirection.Input; ' optional
p2.Size = 13; ' optional
p2.Value = textBox2.Text;

Notice the words in bold in above.

So in your case, the query should look like

insert into TblEmpRegister(EmpID,ECode,EName,Designation,EmailID,MobileNo,ProdUserName,ProdUserPwd,ProdUserRole) values(:IEmpID,:IECode,:IEName,:IDesignation,:IEmailID,:IMobileNo,:IProdUserName,:IProdUserPwd,:IProdUserRole)

Hope this will help, for more example you can visit

Thank u raja i solved my problem by changing column field using : symbol
but some other problem arise i.e

when i was using number datatype data is inserting successfully
i.e insert into employee(empCode,Salary) values(:pEmpcode,:pSalary)
here empcode and salary are number datatype

but when i was using varchar2 type getting error ORA-12571: TNS:packet writer failure

insert into employee(empname,Designation) values(:pEmpname,:pDesignation) //getting error when i was using varchar datatype

please tell me that Oracle.DataAccess.dll will support Oracle 8i

oracleDBtype.varchar2 is not supporting instead of this i am writing as
oracleType.Varchar this is also another problem what to do to support

Please send me solution as soon as possible getting errors while i am using string datatypes
