SQL Server - Export SQL database to xml files
Rédigé par Sozezzo - - Aucun commentaireSQL Script to export table data in xml files, or export schema data to xsd files
This use OLE Automation Stored Procedures (Transact-SQL), and maybe, you need to change the global configuration settings of SQL Server. It can be an issue in production environment, and this case.
The SQL Script have three stored procedures :
#spWriteStringToFile
#spExportTableToXmlFile
#spExportDatabaseToXmlFile
Check GitHub for last version : https://github.com/sozezzo/SqlServer/
You run #spExportDatabaseToXmlFile, and you can filter by the table name or the scheme name.
The filter can use wildcard character : %
Limitation :
Some column type cannot be exported. ( Ex. Type := Geography )
You can change the column type, or copy the data to a new table with transformed columns.
Suggestions
Backup and restore the database over another SQL Server, it is preferable to use develop SQL Server.
Use shared folder with low security to storage xml files.
Fix Error : SQL Server blocked access to procedure 'sys.sp_OACreate' of component 'Ole Automation Procedures'
