According to this answer: https://stackoverflow.com/a/25863597/12304000
We can use something like this in mysql to calculate the time diff between two cols:
SELECT TIMESTAMPDIFF(<INTERVAL>,<timestampFrom>,<timestampTo>);
How can I achieve the same thing with pandasql? I tried these:
from pandasql import sqldf output = sqldf("select DATEDIFF(minute,startDate,completedDate) from df") output = sqldf("select TIMESTAMPDIFF(MINUTE,startDate,completedDate) from df")
but they throw an error that:
OperationalError: no such column: MINUTE

From the PandaSQL documentation:
pandasql uses SQLite syntax.
The link in your post is for MySQL. Here is a reference for SQLite https://www.sqlite.org/lang.html
The syntax would be like:
"select ROUND((JULIANDAY(startDate) - JULIANDAY(completedDate)) * 1440) from df"
