Learn how to convert date values to strings using the TO_CHAR function, which is especially useful for filtering based on a date value.
- [Instructor] The Oracle TO_CHAR sequel function…is especially useful when formatting how…date values are displayed by our sequel query.…So let's see it in action.…We'll start by selecting the first name column…and the hire date column of all employees…in our employees table.…As we can see, hire date is the value…of when an employee initially joined our company.…And as we can see, the format of how date values…are displayed is determined by the…session and database configuration.…
However, we can override it if we want to display…date values using a different format.…For example, maybe you want to see the month name…before the day of the month.…Or instead of seeing month names,…you just want to see a number corresponding to the month.…So one for January, two for February, and so on.…We can accomplish all that using the TO_CHAR function.…So let's see it in action.…We'll type TO_CHAR, and inside brackets specify…hire date, which is the column containing date values…on which we want to apply the TO_CHAR function,…
