Go postgresql LIKE query

Question

I\'m working with Go and PostgreSQL (pq driver), I have the following query

SELECT p.id, p.name, p.description, p.price, p.image, p.rate
FROM products AS p
W         


        

Answer 1

According to this issue your query must not contain '%' sign, but "name" parameter must be quoted by '%'

query := `SELECT p.id, p.name, p.description, p.price, p.image, p.rate
    FROM products AS p
    WHERE LOWER(p.name) LIKE $1 ORDER BY p.rate DESC`

product_rows, err := db.Query(query, fmt.Sprintf("%%%s%%", name))

Answer 2

Dont put qoutes when you are preparing your query. Just provide the value with qoutes and % sign. This will solve the problem. tried and tested.

Solution: query := SELECT p.id, p.name, p.description, p.price, p.image, p.rate FROM products AS p WHERE LOWER(p.name) LIKE $1 ORDER BY p.rate DESC

product_rows, err := db.Query(query, "'%" + name + "%'")

I got my soltion from this thread

You need to put the like pattern in single quotes:

SELECT p.id, p.name, p.description, p.price, p.image, p.rate
FROM products AS p
WHERE LOWER(p.name) LIKE '%' || $1 || '%'
ORDER BY p.rate DESC;
