Building a Retry Mechanism for sqlcmd in Bash

Jose Manuel Jurado Diaz won’t let failure get him down:


Efficiently managing temporary failures and timeouts is crucial in production environments when connecting to databases. In this article, we’ll explore how to implement a retry mechanism with sqlcmd in a Bash script, dynamically increasing timeouts with each failed attempt.

Problem Statement:

Operations can fail due to network issues, overloaded servers, or other temporary problems when interacting with databases. Implementing a retry mechanism helps address these temporary issues without manual intervention.

Read on for the solution script. You could also adapt this to Powershell fairly easily, I think, though if you do go down that road, I’d recommend taking a look at Polly and PsPolly.
