Hello. I am using SQL Server Import and Export Wizard (2017) to import data from Oracle to SQL Server.
Data source: Oracle Provider for OLE DB
Destination: SQL Server Native Client 11.0
Every time I execute an SSIS package, the number of rows in the SQL Server table increases by one row. For example, if table X has 10 rows in Oracle, 11 rows are inserted in SQL Server. If the package is executed again, 12 rows are inserted. There are no error messages either.
Note: This issue only occurs for a specific database and it does not occur for every package.
Does anyone have any idea what the issue is and how to solve it.
