Convert an Integer to a Binary

- Select Field - Administrator
Although there is not a function built-in to Vertica to convert an integer into a binary, you can use the Vertica’s TO_HEX and HEX_TO_BINARY function to create your own!
Example:
dbadmin=> SELECT HEX_TO_BINARY(LPAD(TO_HEX(2 & 0xffffffff), 8, '0'))::VARBINARY INT_TO_BINARY;
INT_TO_BINARY
------------------
\000\000\000\002
(1 row)
dbadmin=> CREATE OR REPLACE FUNCTION int2bin (input INT) RETURN VARBINARY
dbadmin-> AS BEGIN
dbadmin-> RETURN HEX_TO_BINARY(LPAD(TO_HEX(input & 0xffffffff), 8, '0'))::VARBINARY;
dbadmin->
dbadmin-> END;
CREATE FUNCTION
dbadmin=> SELECT int2bin(2);
int2bin
------------------
\000\000\000\002
(1 row)
