Here, we create a function namedCalculateAge. Furthermore, the function utilizes PostgreSQL’s built-inage()function to determine the difference between two dates. Since only one argument is provided,age()calculates the difference between the given date and the current date. Consequently, theCalcula...
AGE() function The PostgreSQL AGE() function subtracts two timestamps, producing a symbolic result that uses years and months. Uses of AGE() Function Calculate Age:Determine the age in years, months, and days between two dates. Date Difference:Find the difference between a specific date and ...
Fixed issue to calculate the day difference and the hour difference, without considering timestamp (i.e., hh:mm:ss.msec). Fixed an issue with DATEDIFF() function to return correct results between two input dates regardless of the input parameters. Fixed an issue with DATEADD() function when...

What is the difference between PostgreSQL and MSSQL? chevron_right PostgreSQL can run on multiple platforms like Linux and Unix, while MSSQL can only run on Windows. Can PostgreSQL handle big data? chevron_right PostgreSQL is preferred for managing read-write operations, large datasets, ...
There is a large difference between the programming languages that the PostgreSQL server supports and that of the SQL server. The programming languages supported by the PostgreSQL server are Python, Tcl, Net, C, C++, Delphi, Java, JavaScript (Node.js), and Perl. SQL Server With regards to...
There are, however, a couple that really can make a huge difference when tuned from the defaults. work_mem is one of them, and max_wal_size is another. max_wal_size controls how large the write-ahead log can get on disk before PostgreSQL does a checkpoint. It’s not a hard limit;...
In both cases, a few hundred individuals work on the main server code. The main difference in the development is that PostgreSQL’s new functionality is open for observation (if you are on the right mailing list) while Oracle often provides little or no notice of something new. ...
INTERVALs are a special data type for representing the difference between two TIMESTAMP types. When subtracting timestamps, Postgres will typically give an interval in terms of days, hours, minutes, seconds, without venturing into months. This generally makes life easier, since months are of ...
There is a downside to using UTF-8: It’s slower than basic “C” encoding. (“C” encoding, as a reminder, just takes the binary strings as it finds them and compares them that way, without regard to what natural language code points they represent.) The difference is significant: on...
