How to Check the Data Type For A Single Column In Oracle?

To check the data type for a single column in Oracle, you can use the DESCRIBE command followed by the table name and column name. This will provide information about the column including its data type, length, and nullability. Alternatively, you can query the USER_TAB_COLUMNS or ALL_TAB_COLUMNS view by specifying the table name and column name to retrieve the data type information. Additionally, you can use the SQL Developer tool to view the table structure and data types for each column visually. These methods can help you easily determine the data type of a single column in an Oracle database.

How can I check the datatype of a column in Oracle table schema?
