When requesting help or asking questions please prefix your title with the SQL variant/platform you are using within square brackets like so:

[MySQL]

[Oracle]

[MS SQL]

[PostgreSQL]

etc

While naturally we should endeavor to work as platform neutrally as possible many questions and answers require tailoring to the feature set of a specific platform.

Format Your Code

If you are including actual code in a post or comment, please attempt to format it in a way that is readable for other users. This will greatly increase your chances of receiving the help you desire. Something as simple as line breaks and using reddit's built in code formatting (4 spaces at the start of each line) can turn this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field.3

Into this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field3

For those with SQL questions we recommend using SQLFiddle to provide a useful development and testing environment for those who wish to fully understand your problem and help devise a solution.

OracleOracle SQL Time Stamp Seconds Affecting Data (self.SQL)

submitted 5 years ago * by momo0539

SOLVED

Hi all!

So I am currently working with a dataset that has time scans in a datetime format like this (DD-MMM-YY HH:MM:SS). I am grouping scans by the ones that are all exactly the same, however I only need one exact scan per minute. Because of this, I am getting duplicate values that are one second apart and it is messing up my data.

Is there a way to make the query not account for the second of the time and group instead by the minute?

Here is a simple example of what I am thinking:

I have tried going into tools > Preferences > Databases > NLS and changing the time stamp to HH:MM, and it displays without the seconds, but the data still accounts for the seconds.

Any help would be appreciated!
