Function binsizedb - size of the specified table or database

Writing functions:

binsizedb(dbid | table)

Where dbid is the name of the variable returned by the opendb function, table is the variable returned by the opentable function. You need to specify the dbid or table parameter

This function returns the size of the specified table or database.

The function that I propose to describe to you performs an important task - calculating the binary size of a database table or the database itself. Let me introduce you to a feature that will help you solve this problem.

The binsizedb function takes as an argument the name of the database table or the name of the database itself. It will return the binary size of the table or database.

Let's figure out how this feature works. First of all, it checks whether the specified table or database exists. If the table or database does not exist, the function returns an error. Otherwise, the function will iterate over each record (row) in the table or each table in the database and add up the data sizes.

To calculate the data size of each record or table, the function will use the following logic. It will first determine the data type of each column (column) in a record or table. Then it will calculate the size of each value in the column.

For example, if we have a column with the INTEGER data type that contains the value 42, the function will simply add the size of the INTEGER data type to the total size of this column. And if we have a column with the VARCHAR data type that contains the string "Hello, world!", the function will calculate the size of the row and add it to the total size of the column.

After the function goes through all the records or tables and calculates the data size of each column, it simply adds up all the sizes to get the total binary size of the table or database.
