Go/Golang sql.DB reuse in functions

Question

sql.Open() returns a variable of type *sql.DB

I have a function that calls 10 other functions that all need to make database calls

Is it more correct/efficient t

Answer 1

You shouldn't need to open database connections all over the place. The database/sql package does connection pooling internally, opening and closing connections as needed, while providing the illusion of a single connection that can be used concurrently.

Probably you need to look elsewhere for the cause of your driver breakage. Some more details about that would make it easier for people to figure out what is going on.
