Hi Iam developing a vb.NET application and trying to insert and update a database table. Will the below update query work? If I set BindByName = True will .NET consider null and SYSDATE as parameters as well? P.S this is shortened query and the actual query is a bit complex and so wanted some confirmation before i try it out

cmd.Parameters.Clear() 
cmd.CommandText = "UPDATE TBL_xxx_xxx SET NEXT=null, ACTIONDATE=SYSDATE, comments=:pcomments, STATUS=11 WHERE ACTIONDATE IS NULL AND WFID=:pwid AND ACTIONBY=:pactionby" 
cmd.CommandType = CommandType.Text 
cmd.BindByName = True

                    cmd.Parameters.Add(New OracleParameter(":pcomments", OracleDbType.Varchar2)).Value = somevalue
                    cmd.Parameters.Add(New OracleParameter(":pwid", OracleDbType.Int64)).Value = somevalue
                    cmd.Parameters.Add(New OracleParameter(":pactionby", OracleDbType.Varchar2)).Value = somevalue

                    cmd.ExecuteQuery()

What I have tried:

Nothing so far..... I wanted some understanding of BindByName before implementing

Solution 1

As the documentation (BindByName[^]) states:

Quote:

6.2.4.5 BindByName

This property specifies the binding method in the collection.

Declaration

C#
// C#
public bool BindByName {get; set;}
Property Value

Returns true if the parameters are bound by name; returns false if the parameters are bound by position.

Remarks

Default = false.

Hi Maciej, Thanks for your reply.

What happens to the NEXT=null, ACTIONDATE=SYSDATE? Will they work as normal update query

The best way to find out is to execute your code ;)
In other words, it should work as expected.

:) .....yes will try it out with a small query before my actual query which is a bit complex
