PR Summary

• Addition of New Columns to 'type' Table
  Two new columns were added to the 'type' table. First is float_col, which will hold numbers with decimals, providing high precision. Second is char_col, which holds character strings up to 100 characters long.
• Introduction of 'blob_col' with Default Value
  An additional column blob_col was introduced to the 'type' table. This type of column is often used to store large amount of binary data like images or files. By default, if no value is provided, this column will be empty (NULL).
• Removal of Certain Columns from 'type' Table
  Two previously existing columns, char_col and blob_col, were removed from the 'type' table. This removal likely reflects a change in the data structure requirements for this table.
