--------------------------------------
Summary: JdbcDataContext.getDefaultSchemaName sometimes give wrong
result
Key: METAMODEL-117
URL: https://issues.apache.org/jira/browse/METAMODEL-117
Project: Apache MetaModel
Issue Type: Bug
Environment: Windows 7 connecting to MySQL
Reporter: Philip Welch
Priority: Minor
I'm using metamodel to connect to mysql. I have several databases - including
once called test (created by default) and once called testmetamodel.
JdbcDataContext.getDefaultSchemaName loops over all schema (i.e. databases)
names accessible via the jdbc connection and takes the first schema which it
can find within the last token of the URL connection (using string.indexof).
The URL connection is jdbc:mysql://localhost/testmetamodel and the last token
is testmetamodel. As I have a database called 'test' and 'test' is a substring
of 'testmetamodel' it incorrectly returns 'test' from getDefaultSchemaName().
Instead of returning the first schema whose name is a substring of the last
token in the URL, it should return the schema with the longest name and whose
name is also a substring of the last token in the URL.
