Enjoy this one from @learnittoolstraining4935 ; this video demonstrates standard SQL practice questions using the HR.Employees employee database table.
Oracle SQL Developer is used to write and execute SQL queries and view the resulting employee records.
This video explains date filtering using conditions such as WHERE and BETWEEN to find employees who joined within specific date ranges, such as 2005–2009.
The TO_CHAR() function is demonstrated for extracting and formatting date information, including years, months, and specific times also covers logical operators and column aliases, including AND, OR, WHERE, and BETWEEN, and explains that double quotes are required for aliases containing spaces.
