Question 1

How do I build dynamic WHERE clauses with Squirrel in Go?

Accepted Answer

Use the Where() method with conditional logic, such as checking if a variable is non-empty before adding a clause. For example, you can chain Where() based on runtime conditions for flexible query building.

Question 2

Squirrel or GORM: which is better for Go database queries?

Accepted Answer

Choose Squirrel if you need precise SQL control without ORM overhead; it's ideal for dynamic queries. GORM is better for full ORM features like associations and migrations, while Squirrel focuses on query generation.

Question 3

How to use Squirrel with PostgreSQL RETURNING clauses?

Accepted Answer

Use the Suffix() method to append RETURNING clauses, and set PlaceholderFormat to sq.Dollar for correct PostgreSQL placeholders. The README example shows this with Insert().Suffix().

Question 4

Does Squirrel support transaction handling with database/sql?

Accepted Answer

Yes, Squirrel integrates directly with database/sql; use RunWith() on a transaction object to execute queries within a transaction, similar to standard Go database practices.

Question 5

How to escape question marks in Squirrel for PostgreSQL queries?

Accepted Answer

Insert two question marks (??) in your SQL string; Squirrel handles escaping based on the placeholder format, converting them appropriately, as explained in the escaping section.

Question 6

Can Squirrel handle composite IN queries with tuples?

Accepted Answer

Squirrel doesn't explicitly support tuples, but you can simulate it using sq.Or with multiple Eq clauses, as shown in the FAQ, which produces an equivalent query plan.
