Accessing Oracle Table Column Names
Knowing the column names in an Oracle database table is crucial for tasks like data verification and report creation. The USER_TAB_COLUMNS
view provides this information.
To get the column names for a table (let's call it MYTABLE
), use this SQL query:
SELECT table_name, column_name, data_type, data_length FROM USER_TAB_COLUMNS WHERE table_name = 'MYTABLE';
This query returns the column names, their data types, and lengths. If MYTABLE
has columns eventID
, eventType
, eventDesc
, and eventTime
, the query will list these with their corresponding data types and lengths.
The USER_TAB_COLUMNS
view simplifies retrieving column names for any table within your Oracle database, aiding in query construction, report generation, and various other database management tasks.
The above is the detailed content of How to Retrieve Column Names from an Oracle Table?. For more information, please follow other related articles on the PHP Chinese website!
