Update of a Child Entity With ConcurrencyMode=Fixed set on both the Child and Parent Fails with: ORA-06550/PLS-0103
Last updated on MAY 17, 2012
Applies to:Oracle Data Provider for .NET - Version 188.8.131.52 and later
Information in this document applies to any platform.
If both the parent and child entities have a column with ConcurrencyMode=Fixed, Entity Framework will attempt to update the parent record whenever the child is modified, even if the parent is not modified. In this scenario, ODP.NET creates a invalid update statement statement and this fails and returns an exception. The same code is successfully with SQL Server.
