How to Cast Full Timestamp Into Date In Oracle?

2 minutes read

To cast a full timestamp into a date in Oracle, you can use the TO_DATE function. This function converts a timestamp value to a date format. The syntax for TO_DATE is: TO_DATE(timestamp_value, format_mask)


For example, if you have a timestamp value '10-FEB-21 12.30.00.000000000 AM' and you want to cast it into a date format, you can use the TO_DATE function like this: TO_DATE('10-FEB-21 12.30.00.000000000 AM', 'DD-MON-RR HH.MI.SS.FF9 AM')


This will convert the timestamp value into a date format that you specify in the format_mask parameter. Remember to adjust the format_mask parameter according to the timestamp format you are working with.


What function can I use to cast a full timestamp into a date in Oracle?

You can use the TO_DATE function to cast a full timestamp into a date in Oracle. For example:

1
2

SELECT TO_DATE('2022-07-15 13:30:00', 'YYYY-MM-DD HH24:MI:SS') AS date_column
FROM dual;


This will convert the timestamp '2022-07-15 13:30:00' into a date format in Oracle.


What options are available for casting a timestamp into a date in Oracle?

In Oracle SQL, there are a few different options available for casting a timestamp into a date:

  1. Using the TO_DATE function: The TO_DATE function can be used to convert a timestamp into a date. The syntax for this function is as follows: TO_DATE(timestamp, format_mask) Example: TO_DATE('2020-01-01 12:00:00', 'YYYY-MM-DD HH24:MI:SS')
  2. Using the CAST function: The CAST function can also be used to convert a timestamp into a date. The syntax for this function is as follows: CAST(timestamp AS DATE) Example: CAST('2020-01-01 12:00:00' AS DATE)
  3. Using the TRUNC function: The TRUNC function can be used to truncate a timestamp to a specified date part, such as year, month, or day. By truncating the timestamp to the day, the time component is removed, effectively converting it into a date. TRUNC(timestamp, 'DAY') Example: TRUNC('2020-01-01 12:00:00', 'DAY')


These are just a few options for casting a timestamp into a date in Oracle SQL. Depending on your specific requirements and the format of the timestamp, you may need to adjust the syntax or use additional functions to achieve the desired result.


What is the recommended approach for casting a timestamp into a date in Oracle?

The recommended approach for casting a timestamp into a date in Oracle is to use the CAST() function or the TO_DATE() function.


Example using CAST() function:

1

SELECT CAST(timestamp_column AS DATE) FROM your_table;


Example using TO_DATE() function:

1

SELECT TO_DATE(timestamp_column, 'YYYY-MM-DD') FROM your_table;


These functions will convert the timestamp data type into a date data type in Oracle.
