How to use wireshark with sdrsharp2/25/2023 Map with drivers declared globally drivers = make(mapdriver.Driver)Īnd then they are initialized by the driver using a method from the standard library func init() How can you implement this simple approach in Go like plugins at runtime - everything we love so much, global variables, init functions, etc. It usually looks like this in code: _ "/lib/pq" We start working with the database by connecting to it sql.Open(“driver_name”, connStr)Īs I already said, there are no specific driver implementations in the standard library - third-party ones are used. I will skip some non-critical points for easier reading - let’s see the driver. But now the project seems to be already outdated and they ask to use in which this dependency reappears! Standardization is our common success! :)īy the way, you can read about mocking a database connection here: It’s simple - the guys went their own way and did not implement the standard interface, and problems started from here - at least I could not mock work with the repository for tests and had to manage with integration tests. Since today we will consider working with a database using PostgreSQL as an example, some of you probably use a fairly popular ORM -, but if you look at the usage example, you will notice that in the imports there is no standard library. And then we just use the implementation (driver) necessary for a particular database. The sense is clear, the general work for all databases is placed in a separate package. take on the complexity of implementing some things.make type casting / conversions consistent between all drivers.The main goals of the standard library are described in the doc.txt file various drivers implementing the standard library interface.What do we have to work with the database? You can see all this in a well-documented library, but I will simplify this process for you - focusing only on essential things. The most common task is getting data from a database - we all know how to do this very well, but let’s see how it works.
