Type-Safe SQL in Go with sqlc
The interfaces provided by the `database/sql` standard library in the Go language are relatively low-level. This requires us to write a large amount of repetitive code. This substantial amount of boilerplate code is not only cumbersome to write but also error-prone. Sometimes, if you modify the field type, you may need to make changes in many places; if you add a new field, you also need to modify the places where the `select *` query statement was previously used. If there are any omissions, it may lead to a panic during runtime. Even if you use an ORM library, these issues cannot be completely resolved! That's where sqlc comes in! sqlc can generate type-safe and idiomatic Go interface code based on the SQL statements we write, and we just need to call these methods.
