[h2] Re: UNSIGNED and array problem in H2 query
Thanks for responding , I am migration my code from H2 1.3.176 to H2 2.1.214 These are the queries that are already being used in the original code . But now as I have upgraded the version of H2 it started to throw this exception . Thanks you.

Re: [h2] Question about recover tool

Or is there any other way to read a database file with the sole purpose of dumping the content of its tables? Not at the moment. The recover tool passes down a flag to make certain parts of the lower level code more tolerant of problems. Certainly that could be extended to cover more situations.

[h2] Re: UNSIGNED and array problem in H2 query
Hello. Where did you find that syntax? There are no unsigned numeric data types in the SQL Standard and in the most of database systems including the H2. This is a feature of MySQL. H2 silently accepts UNSIGNED only in MySQL and MariaDB compatibility modes, but this declaration is ignored by H2 anyway. https://h2database.com/html/features.html#compatibility Also the real MySQL doesn't have the ARRAY data type, so if you use H2 as an replacement of MySQL for unit tests, you shouldn't try to use it. If you use H2 as a primary database, you can use standard-compliant ARRAY data type safely: https://h2database.com/html/datatypes.html#array_type You cannot declare your column as UNSIGNED, but you can add a check constraint to it if you wish. -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
