When importing legacy files into an SQL database, users are exploring alternatives to Microsoft's import/export Wizard. For smaller batches, the Wizard is recommended, but for larger datasets, a custom program may be necessary. The BULK INSERT command is mentioned as a potential solution for importing files, particularly CSVs, although the specific file formats it supports are not detailed. The discussion also touches on the importance of having a similar database schema to the flat files for successful imports. A Java application is suggested for those comfortable with programming, with the potential for a concise codebase depending on the complexity of the data differences. Groovy is also mentioned as a viable alternative to Java, noted for its scripting capabilities and ease of use. The conversation hints at the possibility of further exploration of Groovy's advantages in a future article.
