Array Binds with Tables which include Objects

Array Binds with Tables which include Objects

Hi All

If I try array binding to insert into a table which contains columns of a user defined type I always get an error message:

Code: Select all
Argument 'Iters' must be equal to ArrayLength


I can insert regular column data via array binding and I can insert objects via the normal, round trip each time, binding.

Sooo.... am I correct. Is it not possible to array bind an insert if one of the columns is of type OracleObject? Please advise. If this is the expected behaviour I recommend mentioning this in the documentation - would have saved me a lot of time.

Oracle 9.2, OraDirect 3.1.5, VS 2003 C#

Cheers
Dale

Please see "Working with VARRAY type" article in OraDirect .NET documentation. Please do not set ArrayLength property. It is used for PL/SQL table parameters.

I have looked closely at the VARRAY, Object and Array binding documentation.

You may have mis-understood the question I was asking. What I was trying to do is perform an array insert using binding to an array of OracleObject's. Essentially an array of OracleObject classes. The documentation doesn't say you can do this - but it doesn't say you can't either. So what I was asking was - is it possible? Since array bind inserts with OracleLob objects works OK I thought that a similar thing might be possible with OracleObject classes.

Looks like it is not possible. Thats OK I can use the round trip per row method as illustrated in the documentation which works fine.

Please don't get me wrong - I think you have done a good job on the really complex stuff. I have worked with the OCI dll's and know how hard it is to do. I just recommend an update of the documentation saying something like:

Code: Select all
The use of array binding with OracleObject classes is not supported.

Yes. OraDirect .NET does not support DML array parameters of OracleDbType.Object, OracleDbType.Array,
OracleDbType.Table, OracleDbType.Xml types. We will reflect this in Oradirect .NET documentation.
