Final answer:
The STRUCTURE command does not exist universally across DBMSs. For example, MySQL uses DESCRIBE or SHOW COLUMNS FROM, while SQL Server uses sp_help or the INFORMATION_SCHEMA to view table structures.
Step-by-step explanation:
The structure of a table in a database can usually be viewed using a command, but the specific command to view this structure varies based on the database management system (DBMS) in use. In MySQL, for example, the DESCRIBE command or SHOW COLUMNS FROM command can be used to display the structure of a table, detailing the columns, types, and other attributes. Similarly, in SQL Server, the sp_help command or the INFORMATION_SCHEMA schema can provide this information. However, there is no universal STRUCTURE command across all DBMSs. It's important to refer to the documentation of the specific DBMS you are working with to understand the correct syntax and commands.
