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