Detailed Description

A simple program that reads two CSV files, the first one containing temporal values and the second containing non-temporal values and apply a function to them.

The corresponding SQL query would be

SELECT t1.k, t2.k, numInstants(atTime(temp, t))
FROM tbl_tfloat t1, tbl_tstzspan t2
WHERE atTime(temp, t) IS NOT NULL;

The program can be build as follows

gcc -Wall -g -I/usr/local/include -o tbl_temporal_value tbl_temporal_value.c -L/usr/local/lib -lmeos
