------------------------------------------
Summary: PostgreSQL dialect should support SET, RESET, BEGIN,
SHOW, ROLLBACK, COMMIT
Key: CALCITE-5403
URL: https://issues.apache.org/jira/browse/CALCITE-5403
Project: Calcite
Issue Type: Bug
Components: babel
Reporter: Dmitry Sysolyatin
Assignee: Dmitry Sysolyatin
Babel parser can not parse BEGIN [1], SHOW [2], ROLLBACK [3], COMMIT [4]
commands at the moment.
It can parse SET [5] and RESET [6], but not completely. For instance, it can
not parse the following statement:
{code:java}
SET SCHEMA public,public,"$user"
{code}
The syntax for these commands is as follows:
* BEGIN [1]:
{code:java}
BEGIN [ WORK | TRANSACTION ] [ transaction_mode [, ...] ]
where transaction_mode is one of: ISOLATION LEVEL { SERIALIZABLE | REPEATABLE
READ | READ COMMITTED | READ UNCOMMITTED } READ WRITE | READ ONLY [ NOT ]
DEFERRABLE
{code}
* SHOW [2]:
{code:java}
SHOW (<TRANSACTION ISOLATION LEVEL> | <string literal>)
{code}
* ROLLBACK [3]:
{code:java}
ROLLBACK [ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]
{code}
* COMMIT [4]:
{code:java}
COMMIT [ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]
{code}
* SET [5]
{code:java}
SET [ SESSION | LOCAL ] configuration_parameter { TO | = } { value | 'value' |
DEFAULT }
SET [ SESSION | LOCAL ] TIME ZONE { value | 'value' | LOCAL | DEFAULT }
SET [ SESSION | LOCAL ] { SCHEMA | SEED | NAMES } value
Values can be specified as string constants, identifiers, numbers, or
comma-separated lists of these
{code}
* RESET [6]
{code:java}
RESET <parameter>;
{code}
