Explain how temporary tables can be used and why this is beneficial to the company. Provide
specific examples to support your ideas. Explain why it is important to clear temporary tables
and discuss what could happen if this is not done.
If there is data that a person does not have access to or if they want to use the data
without messing up the current, a person can create a temporary table so that they can manipulate
the data however they want without change the data in the permanent tables. Using temporary
tables allows the manipulation of data without changing the data already in the system, which
means that there will be less corrupted data and less human error. Also, if there needs to be
changes made to the current table, a person can create a temporary table and input the data there,
change the data however they want, then replace the current table data with the temporary table
data. This will allow the access to the table to be longer with less down time.
If a person does not drop a table, most temporary tables will drop when a person exits the
windows. The others temporary tables will be dropped latter in the system. A person can drop the
table before they exit, but there really is no need to.
