Question 1

Is go-sqlbuilder safe from SQL injection?

Accepted Answer

Yes, when using the Build() method with prepared statements, it properly escapes arguments. However, the interpolation feature has security warnings and should be avoided for sensitive data or with untrusted inputs.

Question 2

How to use go-sqlbuilder with PostgreSQL?

Accepted Answer

Use the PostgreSQL flavor by calling PostgreSQL.NewSelectBuilder() or similar methods. This ensures correct syntax like $1 placeholders and supports PostgreSQL-specific features such as UPDATE ... FROM clauses.

Question 3

go-sqlbuilder vs GORM: which one should I use?

Accepted Answer

Choose go-sqlbuilder for flexibility, control over SQL, and multi-database support without driver lock-in. GORM is better for rapid development with automatic migrations and relationships, but it's more opinionated and less customizable.

Question 4

Can go-sqlbuilder generate database migrations?

Accepted Answer

No, it does not include migration tools. It's focused on SQL construction, so you'll need separate libraries like golang-migrate or manual scripts for schema changes.

Question 5

How to handle nested queries with go-sqlbuilder?

Accepted Answer

Use builders as arguments in other builders, as shown in the nested SQL example where a SelectBuilder is passed to create subqueries, enabling complex logic like filtered JOINs or CTEs.

Question 6

Best practices for using Struct as an ORM?

Accepted Answer

Define structs with db tags for column mapping, use field mappers like SnakeCaseMapper for naming conventions, and call Struct methods to generate SQL. Always scan results with Struct.Addr() for proper data binding to struct fields.
