What are the advantages and disadvantages of altering the structure of a MySQL table to facilitate easier summation within SQL queries?
When altering the structure of a MySQL table to facilitate easier summation within SQL queries, the advantages include improved query performance, simplified data retrieval, and easier data analysis. However, the disadvantages may include potential data redundancy, increased storage space usage, and potential impact on existing applications that rely on the original table structure.

echo "Table structure altered successfully";
} else {
echo "Error altering table structure: " . $conn->error;
}
