How to Efficiently Maintain Word Counts Using MySQL Triggers in Insert/Update Scenarios?

MySQL Triggers for Efficient Data Manipulation in Insert/Update Scenarios

Consider two tables: ext_words and ext_words_count. The goal is to create a trigger that maintains the count of words in ext_words_count whenever the ext_words table is updated.

For this task, you initially attempted to use a single trigger:

However, this trigger did not account for the case where the updated word did not exist in ext_words_count. To address this, you considered using separate triggers for insert and update operations:

Despite the insert trigger working successfully, the update trigger still failed to increment the count.

Ultimately, you discovered an alternative solution using conditional statements in a single trigger:

This trigger checks whether the updated word exists in ext_words_count. If not, it inserts the word into the table. Otherwise, it increments the corresponding word count. By leveraging conditional statements, you can now efficiently maintain the word count using a single trigger.
