SQL - Update

The SQL UPDATE statement is used to update values of rows, columns or cells.

Suppose we have a table of student looking like this. The table name is "tblStudent".


Suppose we found error with the home state of the student with StudentID 1001. Suppose he is from TX, not CT. Then we use the following statement to make the change.

update tblStudent set HomeState='TX' where StudentID=1001

The result is below.

Excel - Solver examples

Image
Excel Solver is used to solve optimization problems, which is like solving equations. In this tutorial, we will give a very simple example on how to use Excel Solver. Basic example Suppose your car is low on gasoline. The gasoline is $3/gallon. You have a budget of $50. How much gasoline can you buy? Of course, for a problem this simple, we do not even need a Solver to solve the problem. However, the purpose is to teach the users how to use Excel Solver, so we make the problem extremely simple. We have the following framework: Goal: maximize quantity of gasoline Relationship: cost=quantity * unit price Constraint: cost<=budget 1. In cell B1, we enter unit price "3", in cell B4, we enter the budget 50. In cell B2, we just enter an arbitrary number as the number of gallons. We entered 5. In cell B3, we enter the formula "=B1*B2" to let it be the cost, which equals to 15. 2. Click Solver under the Data menu. 3. A Solver dialog window pops up. In "Set objective...

Excel - Pivot Table

Pivot table is a powerful tool to summarize data and examine data patterns in Excel. Suppose we have 200 rows of data from a farmer, which sells fruit (apple, banana, orange) and vegetable (carrot, spinach) to clients in the US or Canada market, like below: 1. Select Insert > PivotTable 2. Click on PivotTable, then select the data range and where to place the PivotTable. When selecting the data range, the header must be selected. 3. Drag "Category" to Row labels, "Item" to Column labels, "Amount" to Values, and at last, drag "Market" to Report Filter. Note: You can user different fields for filter, row label or column label, depending on your business logic. You do not have to fill all the 4 fields, even only dragging the "Amount" into the "Values" field still produces a nice PivotTable. Again, all depend on your business logic. 4. The result is below. Notice that some cells are blank in the PivotTable. The reason is obvio...

This post is written by Yisong Geng, PhD at Calc LLC. If you need consulting services with Excel, please  contact us . VLOOKUP is one of the most commonly used Excel functions. VLOOKUP function asks for 4 things: The value you want to look up, such as name of a person The data range you want to search If the value is found in the data range, which column contains the value you want the function to return? Whether it is a approximate match or not. The default option is approximate match. This argument is optional and let's ignore it for now. The following table contains first name, last name and age of 4 people. Your task is to find the age of Jan Doe. It can be easily done using VLOOKUP function. The value you want to look up is "Jane", which is at cell "A3" The range of data you want to search, which is "A2:C5" Which column contains the value you want to retrieve? The "Age" is column C, so this argument is 3. The 4th argument is optional and...
