How to Use SQLx\'s `In()` Function to Query MySQL with a Slice of IDs?

Using SQLx to Query MySQL with IN from a Slice

In SQLx, there arises a need to query a table with values stored in a slice. This can be achieved by utilizing the In() helper function.

Code Example

To address the given error, the following code snippet can be employed:

var qids []int

// Populate qids dynamically

query, args, err := sqlx.In("SELECT * FROM quote WHERE qid IN (?)", qids)
if err != nil {
    log.Fatal(err)
}

database.SQL := sqlx.MustConnect("driver_name", "dsn")
query = database.SQL.Rebind(query)  // Assuming database.SQL is a *sqlx.DB

err = database.SQL.Select(&quotes, query, args...)
if err != nil {
    log.Fatal(err)
}

Functionalities

• The In() function prepares the query by taking the arguments and rebinding them.
• Rebind() converts the query to use the appropriate bind variables for the specific database backend.
• By combining In() and Rebind(), the query is prepared and optimized for execution.
