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)
}
