Solution for importing SQL files from mysql is too large or connection timeout When I was on a business trip for development in the field some time ago, there was always a problem with importing databases.

Solve the problem of SqlTransaction exhaustion (SQL processing timeout ). Sometimes the amount of data processed by the program is relatively small, stable, and safe, but the data volume is large, and the initial potential problems are exposed. The original database access code is: sometimes the data volume processed by the program is relatively small, and everything is safe, but the data volume is large, a

The example in this article describes how C # accesses SQL Server to set a link timeout. Share to everyone for your reference.
