## Reading Output Parameters from a Stored Procedure with Resultset
To read output parameters from a stored procedure with resultset, make sure you read all the rows before reading the output parameters:
```go
sqltextcreate := `
CREATE PROCEDURE spwithoutputandrows
@bitparam BIT OUTPUT
AS BEGIN
SET @bitparam = 1
SELECT 'Row 1'
END
`
var bitout int64
rows, err := db.QueryContext(ctx, "spwithoutputandrows", sql.Named("bitparam", sql.Out{Dest: &bitout}))
var strrow string
for rows.Next() {
err = rows.Scan(&strrow)
}
fmt.Printf("bitparam is %d", bitout)
```
