QueryRow executes a prepared query statement with the given arguments. If an error occurs during the execution of the statement, that error will be returned by a call to Scan on the returned [*Row], which is always non-nil. If the query selects no rows, the [*Row.Scan] will return [ErrNoRows]. Otherwise, the [*Row.Scan] scans the first selected row and discards the rest.
Example usage:
var name string
err := nameByUseridStmt.QueryRow(id).Scan(&name)
QueryRow uses [context.Background] internally; to specify the context, use [Stmt.QueryRowContext].
Rest ...args: any[]QueryRowContext executes a prepared query statement with the given arguments. If an error occurs during the execution of the statement, that error will be returned by a call to Scan on the returned [*Row], which is always non-nil. If the query selects no rows, the [*Row.Scan] will return [ErrNoRows]. Otherwise, the [*Row.Scan] scans the first selected row and discards the rest.
Generated using TypeDoc
Stmt is a prepared statement. A Stmt is safe for concurrent use by multiple goroutines.
If a Stmt is prepared on a [Tx] or [Conn], it will be bound to a single underlying connection forever. If the [Tx] or [Conn] closes, the Stmt will become unusable and all operations will return an error. If a Stmt is prepared on a [DB], it will remain usable for the lifetime of the [DB]. When the Stmt needs to execute on a new underlying connection, it will prepare itself on the new connection automatically.
