I have a Look up activity to retrieve an employee ID. For this purpose I compare a date with a timestamp which of course does not work.
How can I convert the timestamp to a date in the Data Flow expression builder?
The Timestamp format is yyyy-MM-dd'T'HH:mm:ss','Z'
The date formate is yyyy-MM-dd
Can someone help?
THanks in advance!
Grtz D.
Please try this expression:
toDate(toString(name of your column))
Default format of toDate function is yyyy-[M]M-[d]d. If you need other format, you can refer to this doc.

I've date in dd-mm-yyyy format, I need the date in yyyy-mm(month) format. I'm using postgresql.
Thanks in advance.
date values don't have any format. Any formatting you see is applied by your SQL client. To turn a date into a string with a specific format, you can use to_char()
to_char(the_column, 'yyyy-mm')
I have hour column with nvarchar format ... like example column is
14:45:56
20:03:25
etc
we know in ADF have toDate and ToTimeStamp to create expression in derived column for example:
I have try
toTimestamp(toString((currentUTC()+ hours(7))),'HH:mm:ss')
but the result is null when i'm trying to review. many big thanks to post the answer ...
You must specify the time format both inside toString() and toTimestamp():
toTimestamp(toString(currentUTC()+ hours(7),'HH:mm:ss'),'HH:mm:ss')
Please help me to convert string to timestamp.
source data is in Excel
Need to convert it as below timestamp
2019-12-15T16:35:53.663-04:00
I tried with.
select from_unixtime(unix_timestamp('12/15/2019 21:18','mm/dd/yyyy'),'YYYY-MM-DDT00:00:00-00:00')
Got below error
Both source pattern and target pattern are wrong in your query. See SimpleDateFormat for reference. Also initial string does not contain the timezone and it is not clear how are you going to derive it as -04:00. In such case it will be UTC timezone used, you can convert to other timezone using from_utc_timestamp.
Timestamp string conversion demo:
select from_unixtime(unix_timestamp('12/15/2019 21:18','MM/dd/yyyy HH:mm'),"yyyy-MM-dd'T'HH:mm:ss.SSSZ")
Result:
2019-12-15T21:18:00.000+0000
I have this date "2018-05-30T16:19:58.016Z" coming from my Angular app.
In Spring, the field date is as follows :
#JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")
private Date date;
The date is well stored, but with this format YYYY-MM-dd.
Is there anything that I'm missing ?
MySql date type can't hold data with timestamp. It has to be datetime in order to contain date time with timestamp data.
You probably have to specify the date format going out to the storage, as #JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'") only specifies the date format for parsing the date into the Date object. Even if your Date has all of the seconds and timezone information, the default Date toString() is still
Formats a date in the date escape format yyyy-mm-dd.
according to the Java 8 docs. So if you are using that, it would most likely drop all that extra information on conversion.
You can look at this Convert java.util.Date to String for information on how to get a Date to a formatted String.
I'm trying to add only the current date in "DD/MM/YYYY" format in a field of type ' timestamp in PostgreSQL' .
I try:
select to_char(now(),'DD/MM/YYYY') as date;
But PostgreSQL return me:
TIP : You will need to rewrite the expression or apply a type conversion.
There is no such thing as "only the date" in a timestamp field. A timestamp field will store timestamps.
Try using the date type instead. Please read about this here.
Also, please consider using the ISO 8601 format instead. Getting used to it helps in a lot of cases.
Human-readable formats like "DD/MM/YYYY" should only be used for presentation.
If you want to use timestamp fields and insert a human-readable formatted dates, then you are looking for:
to_timestamp('05/04/2016', 'DD/MM/YYYY')
If it is about the current date, then Postgres provides the CURRENT_DATE function, which you may use:
SELECT CURRENT_DATE;
INSERT INTO t (timestamp_field) VALUES (CURRENT_DATE);
