What are the potential pitfalls of using numbered IDs (ID2_, ID3_) for different sets of data in a MySQL database with PHP?

Potential pitfalls of using numbered IDs for different sets of data in a MySQL database with PHP include confusion and potential overlap between IDs from different sets of data, making it difficult to manage and query the database effectively. To solve this issue, consider using unique identifiers or composite keys for each set of data to ensure data integrity and prevent conflicts. 

// Example of using unique identifiers for different sets of data in a MySQL database with PHP

// Set unique identifiers for different sets of data
$set1_id = "ID1_";
$set2_id = "ID2_";

// Insert data into the database with unique identifiers
$query_set1 = "INSERT INTO table_name (id, data) VALUES ('$set1_id' . UUID(), 'data1')";
$query_set2 = "INSERT INTO table_name (id, data) VALUES ('$set2_id' . UUID(), 'data2')";

// Query data from the database using unique identifiers
$query_get_set1 = "SELECT * FROM table_name WHERE id LIKE '$set1_id%'";
$query_get_set2 = "SELECT * FROM table_name WHERE id LIKE '$set2_id%'";
