Merge columns to replace existing columns. In Query Editor, ensure that the columns that you want to merge are of Text data type. Right-click a column header, and select Change Type > Text from the context menu. Select two or more columns to be merged. Press the CTRL key, and then click on the column headers to select the columns that you want to merge.
Normally we figure out someone's age with current date subtracting the given birth date. So does it in Excel. Step 1: Enter current date in a blank cell, such as 2016/4/7 in Cell B2. Step 2: In another blank cell (says cell C2), enter the formula =INT((B2-A2)/365), and press the Enter key.
Age = DateDiff(yyyy, Birthdate, Date) to calculate age, but this doesn't quite work. If the birth date hasn't yet occurred this year, the Age value will be off by 1. For example, imagine your birthday is December 31, and you were born in 1950. If today is October 1, 1997, subtracting the year portions of the two dates (1997 â 1950) would indicate that you were 47 years old.
