Many databases may contain entries with inconsistent capitalization in certain fields, such as names. To rectify this, it becomes necessary to find a way to capitalize the first letter of each word in these fields. This tutorial will provide a solution for such a scenario using MySQL.
One way to locate records with incorrect casing is to use a regular expression, such as:
SELECT * FROM people_table WHERE full_name REGEXP BINARY '^[a-z]';
However, MySQL does not have a built-in function to perform word capitalization. To achieve this, a custom function must be created.
Visit this link for an implementation of a function called CAP_FIRST:

To use this function, follow these steps:
UPDATE people_table SET full_name = CAP_FIRST(full_name);
This will effectively capitalize the first letter of each word in the full_name field, transforming entries like fred Jones into Fred Jones.
