Parameterized Statements
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 Guid, Author FROM RSSFeed WHERE Title = ?", "US")
defer rows.Close()
for rows.Next() {
var (
Guid string
Author string
)
rows.Scan(&Guid, &Author)
fmt.Printf("Guid = %s, Author = %s\n", Guid, Author)
}
Reusable Statements
The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.
stmt, _ := db.Prepare("SELECT Guid, Author FROM RSSFeed WHERE Title = ?")
defer stmt.Close()
rows, _ := stmt.Query("US 1")
defer rows.Close()
for rows.Next() {
var (
Guid string
Author string
)
rows1.Scan(&Guid, &Author)
fmt.Printf("Guid = %s, Author = %s\n", Guid, Author)
}
rows, _ = stmt.Query("US 2")
defer rows.Close()
for rows.Next() {
var (
Guid string
Author string
)
rows2.Scan(&Guid, &Author)
fmt.Printf("Guid = %s, Author = %s\n", Guid, Author)
}
