I am new with SQL DATA Compare SDK 10. I am currently experencing this null exception during the call to SqlProvider/GetMigrationSQL. Here's the code excerpt,
Dim provider As SqlProvider
Dim block As ExecutionBlock
Dim str As String
provider = New SqlProvider()
'run the SQL on destination DB server
block = provider.GetMigrationSQL(session, True)
Catch ex As Exception
str = ex.ToString
The details of exception looks like that,
System.NullReferenceException: Object reference not set to an instance of an object. at #8ZK.#j2K.#kOW(#x1K #Zds, ComparisonSession #RlYb, Boolean #hkl) at RedGate.SQLDataCompare.Engine.SqlProvider.#CbL(ComparisonSession #RlYb, Boolean #hkl) at RedGate.SQLDataCompare.Engine.SqlProvider.#DbL(ComparisonSession #RlYb, SelectionDelegate #UKPb, Boolean #hkl) at RedGate.SQLDataCompare.Engine.SqlProvider.GetMigrationSQL(ComparisonSession session, SelectionDelegate select, Boolean runOnTwo) at Thomas.MultiLang.DBSynchronizer.SyncDBData() in C:\Projects\Thomas\Flex\Thomas.Server\Thomas.MultiLang\Manager\DBSynchronizer.vb:line 165"
Throught my online search, I got some sense that about two database tables schema may be different. So i used Redgate Sql compare Tool to compare the two DB and the result was that the two DB were identical.
Could you tell me where went wrong?
