MySQL CLOB Handling: TEXT & LONGTEXT Guide

In MySQL, CLOB (Character Large Object) type data typically refers to text data such as long text, large paragraphs, or big files. CLOB type data in MySQL can be stored using TEXT or LONGTEXT data types.

Common operations for handling CLOB type data include:

1. Inserting CLOB data: When inserting CLOB type data using an INSERT statement, you need to place the text data within the VALUES() of the INSERT statement. For example:

INSERT INTO table_name (clob_column) VALUES ('This is a long text');

1. Querying CLOB data: When using a SELECT statement to retrieve CLOB data, you can directly obtain the CLOB data within the SELECT statement. For example:

SELECT clob_column FROM table_name;

1. Updating CLOB Data: When updating CLOB data with an UPDATE statement, make sure to include the new text data in the statement. For example:

UPDATE table_name SET clob_column = 'Updated text' WHERE id = 1;

1. Removing CLOB data: When deleting CLOB type data, you can directly use the DELETE statement to delete the corresponding data row. For example:

DELETE FROM table_name WHERE id = 1;

In general, handling CLOB data in MySQL is similar to handling other data types, but it is important to pay attention to the data size, storage method, and operations.
