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 FileId, ChildrenNum FROM Files WHERE FileId = ?", "119116") defer rows.Close() for rows.Next() { var ( FileId string ChildrenNum string ) rows.Scan(&FileId, &ChildrenNum) fmt.Printf("FileId = %s, ChildrenNum = %s\n", FileId, ChildrenNum) }
Reusable Statements
The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.
stmt, _ := db.Prepare("SELECT FileId, ChildrenNum FROM Files WHERE FileId = ?") defer stmt.Close() rows, _ := stmt.Query("119116 1") defer rows.Close() for rows.Next() { var ( FileId string ChildrenNum string ) rows1.Scan(&FileId, &ChildrenNum) fmt.Printf("FileId = %s, ChildrenNum = %s\n", FileId, ChildrenNum) } rows, _ = stmt.Query("119116 2") defer rows.Close() for rows.Next() { var ( FileId string ChildrenNum string ) rows2.Scan(&FileId, &ChildrenNum) fmt.Printf("FileId = %s, ChildrenNum = %s\n", FileId, ChildrenNum) }
