Question 1

How to set up Bob code generation for a PostgreSQL database?

Accepted Answer

Configure a database connection in Bob's config file and run the generator command to produce models and factories. The documentation provides detailed steps for each supported dialect.

Question 2

Bob vs sqlc: which is better for type-safe SQL queries in Go?

Accepted Answer

Bob offers a broader toolkit with query building and factory generation, while sqlc focuses solely on generating type-safe functions from SQL. Choose Bob if you need an all-in-one solution, or sqlc for minimalism.

Question 3

Does Bob support database migrations or schema management?

Accepted Answer

No, Bob does not include migration tools; it focuses on query execution, model generation, and testing. You'll need to use separate migration libraries or tools alongside Bob.

Question 4

Can I use Bob with existing Go database/sql connections?

Accepted Answer

Yes, Bob is designed to cooperate with the standard library and other tools, allowing integration with existing database/sql connections as per its philosophy of cooperation.

Question 5

How to handle complex joins with Bob's query builder?

Accepted Answer

Use the dialect-specific query builder with query mods to construct joins, similar to the examples in the README. For type-safety, rely on generated models and mods for schema-aware joins.

Question 6

Is Bob suitable for high-performance applications with heavy database usage?

Accepted Answer

Bob emphasizes correctness and type-safety, which can reduce bugs, but the code generation layer might add overhead compared to hand-written SQL. Benchmark for your use case, as performance depends on query complexity.
