Problem when editing a file created with SQL Server Integration Services in Visual Studio

When copying the conversion destination and conversion source of an SSIS package created in SQL Server using Visual Studio, the copy source is safe, but the data is added to the copied table without being deleted (the copy source table is deleted by deleting data → adding data). Creating.

    It seems like you're encountering an issue with the behavior of your SSIS package when copying data from a source table to a destination table. Here are a few points to consider and potential solutions: Truncate Destination Table: Before copying data to the destination table, you can truncate the destination table to remove all existing data. Truncating the table is more efficient than deleting rows one by one. You can use an Execute SQL Task in your SSIS package to execute a SQL statement like TRUNCATE TABLE DestinationTableName. Data Flow Task Configuration: Ensure that your Data Flow Task in the SSIS package is configured correctly. Check the mappings between source and destination columns to ensure that data is copied accurately. Check Data Flow Components: Make sure that the data flow components, such as Source and Destination, are configured properly. The source should retrieve data from the correct table, and the destination should write data to the correct table. Validation and Error Handling: Implement validation and error handling in your SSIS package to capture any errors that occur during the data transfer process. You can use error outputs, error logging, and event handlers to handle errors gracefully. Debugging: Use debugging tools in Visual Studio to step through your SSIS package and identify any issues. You can set breakpoints, inspect variables, and view data at each stage of the data flow process.

    By implementing these suggestions and carefully reviewing your SSIS package configuration, you should be able to resolve the issue of data being added to the destination table without being deleted from the source table.
