After creating a table, it is important to understand its structure.
Table structure includes column names, data types, and constraints.
SQL provides commands to view table structure.
Before viewing table structure, the database must be selected.
SQL commands work only on the active database.
This ensures correct table information is displayed.
The DESCRIBE command is used to view table structure.
It shows column names, data types, null rules, and key information.
This command does not modify data.
Developers use structure commands to verify table design.
This helps confirm whether columns are defined correctly.
Checking structure is a common practice before inserting data.
Viewing table structure helps in debugging database issues.
It allows developers to understand existing tables quickly.
This skill is very useful in real project environments.
