I have a Cassandra table that looks something like this
VmwareVirtualMachine | 2020-04-24 02:04:57+0000
VmwareVirtualMachine | 2020-05-14 06:02:23+0000
VmwareVirtualMachine | 2020-05-14 06:02:23+0000
VmwareVirtualMachine | 2020-06-26 13:19:03+0000
VmwareVirtualMachine | 2020-06-29 06:14:00+0000
My requirement is to print all rows that are less than or equal to 2020-05-14 06:02:23+0000
My query is:
cqlsh -ksd -e "select type, timevalue from table_one where timevalue != null and timevalue<='2020-05-14 06:02:23+0000'"
It prints
VmwareVirtualMachine | 2020-04-24 02:04:57+0000
Since I gave <= I expected it to print
VmwareVirtualMachine | 2020-04-24 02:04:57+0000
VmwareVirtualMachine | 2020-05-14 06:02:23+0000
VmwareVirtualMachine | 2020-05-14 06:02:23+0000
If I do something like this:
cqlsh -ksd -e "select type, timevalue from table_one where timevalue != null and timevalue<='2020-05-14 06:02:24+0000'"
It prints the first 3 rows if I increase the time by a second. Not sure why less than or not equal to does not work in my statement.
Any help?
