如何在SQL Server 2014中解决System.OutOfMemoryException

Question

My scenario is my live database is on Azure database name vlproduction and I am using SQL Server 2014 on my local machine, database name testvlproduction . For some reason, my testvlproduction database was deleted.

I want to generate testvlproduction to be the same as vlproduction but I found there is no way to take direct backup of live so I generate script with data but script is too big (300mb) whenever I'm trying to run script on my local it shows

System.OutOfMemoryException

Please tell me, what to do to fix this ? or is there another way to generate database same as live on local

Is there already built any such functionality in SQL Server?

May be this question repeated but still I have no solution for my issue.

Fill free to ask any query.

Thanks

Answer 1

This is a limitation of sql server,This happen because Management Studio is running out of memory, not the SQL Server service. This is likely caused by the size of the result set that you are returning to Management Studio.

See https://support.microsoft.com/en-in/kb/2874903 for more details. For more sql-server-management-studio-cant-handle-large-files

Answer 2

Since your SSMS runs out of memory you should try it with the a new release . It should be compatible with SQL Server 2014.

If you have some idle time on your production database take a db backup and restore it locally - use Export Data Tier Application and select the proper version where you want to restore. If this is not an option for you I'd suggest to take @mohan111 's suggestion of committing your script in batches.

I believe you have two problems:

1. System out of memory exception - This usually happens while running big scripts in SSMS. One work around is to run it using command prompt using sqlcmd command (see the link - https://msdn.microsoft.com/en-us/library/ms180944.aspx )

2. Creating Test Database with the same schema as that of production - You can make use of SSDT tool in Visual Studio. This will help you to create a database project which mimics the production database and you can use the publish functionality to create database where ever required which will have the same schema
