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 Filesize, Filename FROM Notes WHERE FilePath = ?", "/documents/doc.txt")
defer rows.Close()
for rows.Next() {
        var (
                Filesize string
                Filename string
        )

        rows.Scan(&Filesize, &Filename)
        fmt.Printf("Filesize = %s, Filename = %s\n", Filesize, Filename)
}

Reusable Statements

The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.

stmt, _ := db.Prepare("SELECT Filesize, Filename FROM Notes WHERE FilePath = ?")
defer stmt.Close()

rows, _ := stmt.Query("/documents/doc.txt 1")
defer rows.Close()
for rows.Next() {
        var (
                Filesize string
                Filename string
        )

        rows1.Scan(&Filesize, &Filename)
        fmt.Printf("Filesize = %s, Filename = %s\n", Filesize, Filename)
}

rows, _ = stmt.Query("/documents/doc.txt 2")
defer rows.Close()
for rows.Next() {
        var (
                Filesize string
                Filename string
        )

        rows2.Scan(&Filesize, &Filename)
        fmt.Printf("Filesize = %s, Filename = %s\n", Filesize, Filename)
}
