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 TradingAccountUUID, Name FROM TradingAccounts WHERE TradingAccountUUID = ?", "c2ef66a5-a545-413b-9312-79a53caadbc4")
defer rows.Close()
for rows.Next() {
        var (
                TradingAccountUUID string
                Name string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT TradingAccountUUID, Name FROM TradingAccounts WHERE TradingAccountUUID = ?")
defer stmt.Close()

rows, _ := stmt.Query("c2ef66a5-a545-413b-9312-79a53caadbc4 1")
defer rows.Close()
for rows.Next() {
        var (
                TradingAccountUUID string
                Name string
        )

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

rows, _ = stmt.Query("c2ef66a5-a545-413b-9312-79a53caadbc4 2")
defer rows.Close()
for rows.Next() {
        var (
                TradingAccountUUID string
                Name string
        )

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