PostgreSQL: CAST function
Question
I have a problem with a CAST function in PostgreSQL. In particular, I have to convert an arithmetic operation (a percentage calcul), where the operands are int type, in a bigint type. But when I type this command:
CAST(("Language".percentage * "Population".population) AS bigint) /100.0 AS pop_speak_lang
The outcome is:
ERROR: integer out of limits
If someone could help me I would really appreciate!
