How Can I Use pq.Array to Pass Integer Slices as Arguments in SQL Queries?

Incorporating Slice Arguments into SQL Queries with pq.Array

When attempting to execute an SQL query that includes a slice of integers as arguments, users may encounter the error: "sql: converting argument $1 type: unsupported type []int, a slice of int." To overcome this issue, the pq.Array function can be utilized.

Problem:

Consider the following code:

somevars := []int{1, 2, 3, 4}
rows, err := db.Query("SELECT c1,c2 FROM table"+tid+" WHERE c1 IN(,,,);", somevars)

Executing this query yields the error: "sql: converting argument $1 type: unsupported type []int, a slice of int."

Solution:

To address this problem, pq.Array can be used to encapsulate the slice of integers into a single argument:

somevars := []int{1, 2, 3, 4}
rows, err = db.Query("SELECT c1,c2 FROM table"+tid+" WHERE c1 = any();", pq.Array(somevars))

The pq.Array function converts the slice of integers into an array representation, enabling it to be correctly handled by the SQL query. By using pq.Array, slice arguments can be effortlessly incorporated into SQL queries, resolving the error message.
