Re^3: DBI Placeholders and DB2 Integers

Well I am certainly not doing anything intentional to use BigInts.

However I notice that the Math::Base36 module uses BigInts and I do use the Base36 module. In fact I use the Base36::decode_base36() function in the same part of code which is doing this DB2 update (I have to extract the integers from a Base36 encoded string).

How do I limit the context of the BigInt? Alternatively, since I haven't used (or heard of) numify before, is that a standard fucntion in Perl v5.8.8 or do I need to pull in another module?

However I notice that the Math::Base36 module uses BigInts... In this case, it's probably easiest to ->numify them, which is a method provided by the Math::BigInt module. In other words, there's no need to load any other module. Your numbers already are objects of type Math::BigInt, so you can simply say `$doc_len->numify`, etc. (Don't use `->as_int` instead (as mentioned in the docs), because this method wouldn't remove the Math::BigInt type...)

SUCCESS! What I have done is 'decode' the base 36 string into a string of regular base 10 numbers and *then* split this into its component parts. (Previously I was splitting the base 36 string and then decoding each component directly to a numeric variable). The result is that the numeric variables get initialised as regular integers and the DBI module is then happy to use them with the prepared place holders. Many thanks Eliya, et al, as this had been driving me nuts for about a day and a half. Guess I should have checked with The Monks earlier! :-)	[reply]
