To check the data type for a single column in Oracle, you can use the DESC command followed by the table name and column name. This will display the data type, length, and other characteristics of the specified column in the table. Another way is to query the data dictionary views such as USER_TAB_COLUMNS or ALL_TAB_COLUMNS to retrieve information about the data type of a specific column in a particular table. By querying these views, you can get detailed information about the data type, precision, scale, and other attributes of the column in Oracle database.

How to identify the data type for a specific column in an Oracle table?
To identify the data type for a specific column in an Oracle table, you can use the following SQL query:
1
|
DESCRIBE table_name;
|
Replace "table_name" with the name of the table you want to check. This query will provide you with a list of columns in the table along with their corresponding data types. For example, if you want to check the data type of a column named "column_name" in a table named "employees", you can run the following query:
1
|
DESCRIBE employees;
|
Look for the specific column you are interested in, and the data type will be listed next to it. You can refer to Oracle's documentation for a list of possible data types and their meanings.
