Execute Stored Procedures

 

EXECUTE with OUTPUT parameter

Execute the dbo.cuspSumRideHrsSingleDay stored procedure and capture the output parameter.


DECLARE @RideHrs AS numeric(18,0)

-- Execute the stored procedure

EXEC dbo.cuspSumRideHrsSingleDay

    -- Pass the input parameter

@DateParm = '3/1/2018',

    -- Store the output in @RideHrs

@RideHrsOut =  @RideHrs OUTPUT

-- Select @RideHrs

SELECT @RideHrs AS RideHours



EXECUTE with the return value

Execute dbo.cuspRideSummaryUpdate to change the RideHours to 300 for '3/1/2018'. Store the return code from the stored procedure.

DECLARE @ReturnStatus AS int

-- Execute the SP, storing the result in @ReturnStatus

EXEC @ReturnStatus = dbo.cuspRideSummaryUpdate

    -- Specify @DateParm

@DateParm= '3/1/2018',

    -- Specify @RideHrs

@RideHrs = 300


-- Select the columns of interest

SELECT

@ReturnStatus AS ReturnStatus,

    Date,

    RideHours

FROM RideSummary

WHERE Date = '3/1/2018';


Exercise

EXECUTE with OUTPUT & return value

Store and display both the output parameter and return code when executing dbo.cuspRideSummaryDelete SP.


-- Create @ReturnStatus

DECLARE @ReturnStatus AS INT

-- Create @RowCount

DECLARE @RowCount AS INT


-- Execute the SP, storing the result in @ReturnStatus

EXEC @ReturnStatus = dbo.cuspRideSummaryDelete

    -- Specify @DateParm

@DateParm = '3/1/2018',

    -- Specify RowCountOut

@RowCountOut = @RowCount OUTPUT


-- Select the columns of interest

SELECT

@ReturnStatus AS ReturnStatus,

    @RowCount AS 'RowCount';

Binomial Test in Python

  Binomial Test Let’s imagine that we are analyzing the percentage of customers who make a purchase after visiting a website. 1000 customers visited the site this month, and 58 of them made a purchase. The marketing department reports that historical data suggests about 72 of every 1000 visitors make a purchase. Thus, they estimate that the probability of any particular customer making a purchase is 7.2%. We would like to know if this month’s number, 58 purchases, is significantly different from normal or a reasonable fluctuation due to random chance. In previous exercises, we collected samples of numerical information (eg. order price) and then used the mean and standard deviation of those samples to make comparisons. In contrast, we now have a sample where each unit (a visitor) falls into one of two discrete categories: “made a purchase” “did not make a purchase” Instead of comparing sample means, we want to compare the percent in the “made a purchase” category to some expectatio...

Slicing and Indexing in Python Pandas

Python Syntax and Functions Part2 (Summary Statistics)

The  .agg()  method allows you to apply your own custom functions to a DataFrame, as well as apply functions to more than one column of a DataFrame at once, making your aggregations super efficient. In the custom function for this exercise, "IQR" is short for inter-quartile range, which is the 75th percentile minus the 25th percentile. It's an alternative to standard deviation that is helpful if your data contains   import numpy as np def iqr(column):     return column.quantile(0.75) - column.quantile(0.25) # Update to print IQR and median of temperature_c, fuel_price_usd_per_l, & unemployment print(sales[["temperature_c", "fuel_price_usd_per_l", "unemployment"]].agg([iqr, np.median])) Calulating Cumulative Statistics Syntax = df.drop_duplicates sales_1_1 = sales_1_1.sort_values("date") # Get the cumulative sum of weekly_sales, add as cum_weekly_sales col sales_1_1["cum_weekly_sales"] = sales_1_1["weekly_sales...
