How to Get the Equivalent of MySQL's SHOW CREATE TABLE in Oracle SQL?

Oracle SQL Equivalent of MySQL's SHOW CREATE TABLE

In MySQL, the SHOW CREATE TABLE command provides a detailed view of a table's definition, including column names and data types.

Oracle SQL does not have an exact equivalent to SHOW CREATE TABLE. However, there are two options available for retrieving similar information:

1. SQL*Plus Command: DESC

For SQL*Plus commands, you can use the DESC command to display the structure of a table:

SQL> DESC EMP;

2. DBMS_METADATA Package:

If you prefer a SQL statement, you can use the DBMS_METADATA package:

SELECT dbms_metadata.get_ddl('TABLE', 'EMP', 'SCHEMA_NAME');

Note: Replace SCHEMA_NAME with the name of the schema the table belongs to.

Additional Considerations:

• For long definitions that exceed the default display limit in SQL*Plus, it is recommended to use the SET LONG 10000 command before executing the DESC or DBMS_METADATA query.
• The DBMS_METADATA output will include additional details, such as primary key constraints and table storage attributes, which may not be directly comparable to MySQL's SHOW CREATE TABLE results.
