[jira] [Updated] (IGNITE-6772) SQL exception messages are not
descriptive
[ https://issues.apache.org/jira/browse/IGNITE-6772?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pavel Tupitsyn updated IGNITE-6772:
-----------------------------------
Description:
Top level SQL exception messages are cryptic and not descriptive. Real details are buried deep inside inner exceptions.
For example, when there is a typo in table name, exception looks like this:
{code}
class org.apache.ignite.IgniteCheckedException: Failed to parse query: SELECT "persons-sql"."PERSON"._KEY, "persons-sql"."PERSON"._VAL from Person1, "orgs-sql".Organization where Person.OrgId = "orgs-sql".Organization._key and "orgs-sql".Organization.Name = ?

As we can see, top level message is {{Failed to parse query}}, but the real problem that user needs to know is {{Table "PERSON1" not found}}. We should make sure that top level message includes the useful information and not some internal implementation details.
Make sure to add unit tests for common SQL query problems:
* Incorrect table name
* Incorrect column name
* Syntax error (shoukd include character index)
Error messages are part of the API.
