Question: I have a date field in an Oracle table and I want to insert a new record. I'm trying to insert a date with a time component into this field, but I'm having some problems.
This Oracle tutorial explains how to use the Oracle / PLSQL FROMTZ function with syntax and examples. The Oracle / PLSQL FROMTZ function converts a TIMESTAMP value (given a TIME ZONE) to a TIMESTAMP WITH TIME ZONE value. Oracle TODATE The Oracle TODATE function converts a date literal to a DATE value.
How can I insert this value into the table.
For example, the value is '3-may-03 21:02:44'
Answer: To insert a date/time value into the Oracle table, you'll need to use the TO_DATE function. The TO_DATE function allows you to define the format of the date/time value.
For example, we could insert the '3-may-03 21:02:44' value as follows:

5 is represented by
Jan is represented by
2017 is represented by
YYYY that results in the following format:
Second, you pass both arguments, date literal and format model, to the
TO_DATE() function as shown below:
The following illustrates the output:
Oracle Get Utc Date

TO_DATE() function will issue a respective error.
For example, if you miss one character Y in the date format model above:
TO_DATE() function issued the following error:

Here is another example of inserting a date value a DATE column using the
TO_DATE() function for formatting.
You can check whether the data was actually inserted by using the following query:
