Querying with Go refers to the process of extracting data from a database using Go programming language. Go provides various libraries and packages to interact with different types of databases like MySQL, PostgreSQL, MongoDB, etc.

The process of querying a database with Go involves establishing a connection to the database, forming a query using SQL or other database specific query languages, executing the query, and retrieving the result set.

Go's database/sql package provides a high-level API for interacting with databases, but developers can also use third-party libraries like GORM or SQLx to simplify the database interaction process.

To query a database in Go, developers need to define the database schema using structs or tags. Then, they can use database/sql to prepare and execute SQL queries to fetch, insert, update or delete data from the database.

Go's concurrency support also allows for efficient querying of databases with large amounts of data. Developers can use channels and goroutines to concurrently execute queries and retrieve results in a scalable and efficient manner.

Overall, querying with Go is a powerful and flexible approach to working with databases, and it allows developers to easily perform common database operations using Go's modern programming paradigms.
