This is a list of trivial features for Sequence (originally mentioned as part of
- Support syntax "CREATE SEQUENCE x AS <some_int_type>';
<some_int_type> can mean all the integers that we support
Currently (as per documentation) maximum value that sequence can support is 9223372036854775806.
But unsigned bigint can have maximum (unsigned) value: 18446744073709551615
So adding support for this maximum (unsigned) value is needed.
Also, set maximum minimum based on the datatype
- Allow in parser very big numbers (decimal) for MAXVALUE but change these to LONGLONG_MAX-1, with a note for the user. This is needes as it's common practice to use
MAXVALUE 9999999999999999999999999999 in Oracle examples.
- Create information_schema.sequences that lists all sequences and their information. Should work similar to views:
select * from information_schema.sequences where table_schema="test";
The column names are:
SEQUENCE_CATALOG, SEQUENCE_SCHEMA, SEQUENCE_NAME, DATA_TYPE, NUMERIC_PRECISION, NUMERIC_PRECISION_RADIX, NUMERIC_SCALE, START_VALUE, MINIMUM_VALUE, MAXIMUM_VALUE, INCREMENT, CYCLE_OPTION, DECLARED_DATA_TYPE, DECLARED_NUMERIC_PRECISION, DECLARED_NUMERIC_SCALE
