The following code example shows how to bind parameters to create parameterized statements.

Single-Use Statements

The Query and Exec functions both accept additional parameters for binding query parameters to values.

rows, _ := db.Query("SELECT unid, FirstName FROM Person WHERE City = ?", "Miami")
defer rows.Close()
for rows.Next() {
        var (
                unid string
                FirstName string
        )

        rows.Scan(&unid, &FirstName)
        fmt.Printf("unid = %s, FirstName = %s\n", unid, FirstName)
}

Reusable Statements

The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.

stmt, _ := db.Prepare("SELECT unid, FirstName FROM Person WHERE City = ?")
defer stmt.Close()

rows, _ := stmt.Query("Miami 1")
defer rows.Close()
for rows.Next() {
        var (
                unid string
                FirstName string
        )

        rows1.Scan(&unid, &FirstName)
        fmt.Printf("unid = %s, FirstName = %s\n", unid, FirstName)
}

rows, _ = stmt.Query("Miami 2")
defer rows.Close()
for rows.Next() {
        var (
                unid string
                FirstName string
        )

        rows2.Scan(&unid, &FirstName)
        fmt.Printf("unid = %s, FirstName = %s\n", unid, FirstName)
}
