Back-end Database

First, add a new column to the table, name it YearMonth and populate it with the concatenation of the Year and Month data. See figure 3. The original table is on the left. With this setup, we can easily select data within the desired year and month range from the table.

Use ROW_NUMBER function to generate row number for each row of the result set. Then we can use the row number to populate the slider range of values. The query shown below returns sixty two rows and this means that the slider range of values goes from one to sixty two. In other words we can set the minimum and maximum properties of the slider to one and sixty two respectively.
