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 Name, Country FROM AdAccounts WHERE Id = ?", "43567234")
defer rows.Close()
for rows.Next() {
var (
Name string
Country string
)
rows.Scan(&Name, &Country)
fmt.Printf("Name = %s, Country = %s\n", Name, Country)
}
Reusable Statements
The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.
stmt, _ := db.Prepare("SELECT Name, Country FROM AdAccounts WHERE Id = ?")
defer stmt.Close()
rows, _ := stmt.Query("43567234 1")
defer rows.Close()
for rows.Next() {
var (
Name string
Country string
)
rows1.Scan(&Name, &Country)
fmt.Printf("Name = %s, Country = %s\n", Name, Country)
}
rows, _ = stmt.Query("43567234 2")
defer rows.Close()
for rows.Next() {
var (
Name string
Country string
)
rows2.Scan(&Name, &Country)
fmt.Printf("Name = %s, Country = %s\n", Name, Country)
}
