# Initial Problem Statement:\nThe task is to find the IDs of invalid tweets where the number of characters in the content exceeds 15.\n# Solution\n```\nSELECT tweet_id FROM Tweets\nWHERE LENGTH(content) > 15;\n```\n# Extended Problem Statement:\nIf the problem statement is modified such that a tweet is considered invalid if it contains more than 2 words, the following solution can be used:\n# Modified Solution:\n```\nSELECT tweet_id\nFROM Tweets\nWHERE LENGTH(content) - LENGTH(REPLACE(content, \' \', \'\')) + 1 > 2;\n```\n- LENGTH(content): This returns the total length of the content\n- REPLACE(content, \' \', \'\'): This removes all spaces from the content.\n- LENGTH(content) - LENGTH(REPLACE(content, \' \', \'\')): This calculates the number of spaces in the content\n- Adding 1 to the number of spaces gives the number of words.\n- The condition LENGTH(content) - LENGTH(REPLACE(content, \' \', \'\')) + 1 > 2 checks if the number of words is greater than 2.\n\n# Don\'t forget to upvote plz\n![up vote catjpg.jpg](https://assets.leetcode.com/users/images/3f83fbcc-e239-4b5e-8ed4-3c5b5c6e47e3_1719041484.4801657.jpeg)\n\n
