Hi Shaterra!
Thanks for reaching out.
The number in parentheses after VARCHAR
specifies the maximum number of characters allowed in that field. To determine what number to use, consider the data you expect to store. When using VARCHAR(50)
, it means any string up to 50
characters can be stored. If you expect a column to contain names, VARCHAR(50)
might be sufficient. If it's for descriptions, you might need more, like VARCHAR(255)
. Always choose a length that fits well with the column description. Using VARCHAR(255)
could be sufficient for most of the tables.
Hope this helps.
Best,
