Обсуждение: Find datatype of a column during the backend flow
Hi,
In the sorting code, I need to determine the datatype of my sort keys and call some code conditionally based on the datatype. Is there any way to determine the datatype of a column from the backend PostGreSQL code. I am aware of the methods PSQLexec() and PQftype() but am unable to figure out how to call these functions from the backend. Any help on this or any other method to determine datatype would be very much appreciated.

Could you please provide a query? -- Kind regards, Sergey Konoplev PostgreSQL Consultant and DBA http://www.linkedin.com/in/grayhemp +1 (415) 867-9984, +7 (901) 903-0499, +7 (988) 888-1979 gray.ru@gmail.com
