This means that the maximum size of a default INT in CockroachDB is much larger than JavaScript can represent as an integer. An int-returning method can't return null. This differs from the PostgreSQL default for INT, which is 32 bits, and may cause issues for your application if it is not written to handle 64-bit integers, whether due to the language your application is written in, or the ORM/framework it uses to generate SQL (if any).įor example, JavaScript language runtimes represent numbers as 64-bit floats, which means that the JS runtime can only represent 53 bits of numeric accuracy and thus has a max safe value of 2 53, or 9007199254740992. at 10:29 2 'but it returns null, if there string has non-integer value' No it doesn't. Considerations for 64-bit signed integersīy default, INT is an alias for INT8, which creates 64-bit signed integers. Smaller values take up less space than larger ones (based on the numeric value, not the data type). The different integer types place different constraints on the range of allowable values, but all integers are stored in the same way regardless of type. You have two main errors that immediately leap to mind: First you're trying to parse the JTextField itself, not the text it holds (as pointed out by dantuch - 1+ to him). 9223372036854775807 to +9223372036854775807Ī constant value of type INT can be entered as a numeric literal. A default value and one-way conversion are also supported for legacy data situations. ![]() ![]() ![]() For instructions showing how to auto-generate integer values (e.g., to auto-number rows in a table), see this FAQ entry.
