This is very helpful if TAP_SCHEMA (or some of its tables and their columns)
has a different name in the database.
The mapping can be specified to JDBCConnection or directly in the configuration
file.

This is particularly annoying for numeric functions like sqrt(...)
(example query: SELECT TOP 1 sqrt(2) as s2 FROM whatever_table).
This bug has been raised by M. Taylor.

Execution duration should be expressed in seconds in this TAP endpoint,
but the TAP Library was returning its internal value which is expressed in
milliseconds.

Schema were still ordered by schema_name instead of schema_index when this
latter exists.

Commit following 6fc7f8fd.

TAPTable.copy(...) and TAPColumn.copy(...) use directly the attribute dbName
instead using getDBName() ; indeed getDBName() <> dbName.
Because of this bug, queries with aliased tables did not work anymore.

These two columns let recommend an order, respectively, for tables in their
schema, and columns in their table.
In addition of these new columns, "arraysize" has been also added.
All these new columns are already supported when creating a TAP_SCHEMA from
an XML file.

[ADQL] SqlServerTranslator: bug fix for TOP vs LIMITgrammar. Adding support for math functions, including translations for TRUNCATE and MOD non-standard implementation.

Before correction, if an ADQlObject (e.g. a function or a sub-query) contains
another ADQLObject and that both (i.e. parent and child) are matching in a
SimpleReplaceHandler and are asked to be replaced, only the parent
seemed to have been replaced. However, the child has been replaced, but
in the former instance of the parent ; and so its replacement is not
visible in the final query.

For instance:
if all mathematical functions must be replaced by a dumb UDF named 'foo' in
the ADQL query:
        "SELECT sqrt(abs(81)) FROM myTable"
,the result should be:
        "SELECT foo(foo(81)) FROM myTable"
,but before this correction it was:
        "SELECT foo(abs(81)) FROM myTable".

This function was originally static. Since no other classes benefits of this
static state, this function is no longer static. This might however raise a
small incompatibility for the users of the library which used it.

Before this commit, unsigned integers were also allowed (as for ORDER BY).

Because of a test of the first parameter (non existing for functions
like PI() and RAND()), a NullPointerException was thrown and so
was stopping brutally an ADQL query interpretation.

See the commit bd621842,
for the first part of the fix (which actually did not really
fixed the problem: connections "idle in transaction" were
still in the database ; the connection being inside an opened transaction,
it generates lock issues in the database in addition of probably taking
some memory resources).

The transaction and Statement were closed too early before.
  - Fetching the row was not possible once the first bunch of fetched
rows was over.
  - The problem of "statement is aborted" preventing the re-use of
a same DB connection was apparently still there, but occurred less often.

  Now, any transaction potentially started in a DB connection is always
closed after one of the public functions of JDBCConnection is called ;
except executeQuery(ADQLQuery) whose the call MUST be wrapped inside a
try...catch block in which DBConnection.cancel(true) MUST be called
in case of error (in order to effectively end any started transaction).

deals with NATURAL JOINs and JOINs using the keyword USING so that being
supported by SQL Server. Basically, they are translated as a list of ON
conditions.
Warning: This translator is just guaranteed to solve the NATURAL and USING
issue. Support for datatypes conversion and case sensitivity has to be
reviewed. Besides no geometrical function is translated for SQL Server.

in first position. This should be totally harmless and should be conform to
the behaviour of a NATURAL or USING keywords in DBMS.

This is easily possible for concatenations, string constants and User Defined
Functions having a FunctionDef. A new special datatype was needed for
numeric functions and operations: UNKNOWN_NUMERIC. This special type
can not be set with FunctionDef.parse(...) and it behaves exactly like the type
UNKNOWN, except that DBType.isNumeric() returns true (as .isUnknown()).
Thus, while writing the metadata of a result in TAP, nothing changes:
an UNKNOWN_NUMERIC type will be processed similarly as an UNKNOWN type:
to use the type returned from the database ResultSet or to set VARCHAR.
(no modification of TAP was needed for that)

Functions whose some parameters are another function were not correctly
identified: since the inner functions were not yet identified, their type
was UNKNOWN and so it makes the identification of the parent function
much easier since an UNKNOWN parameter is not checked. But, it was a
problem if the parameter occurs to be finally of the wrong type.

generated as before, and then, if a job is created, it is set to the ID of the
HTTP request. This modification aims to greatly help the log analysis.

ID set by the TAP library was replaced by the one of the TAP library. The
consequence was a possible bad logging and since the ID is a timestamp, the
ID of the request was indicating a time posterior to a job creation.

Can be enabled just by providing a file URI in the TAP configuration file using
the property "examples". It is also possible to add manually a TAP resource
whose the returned name must be "examples" like the new TAP resource is doing:
tap.resource.Examples. This latter take a file URI as the TAP configuration
file does. The referenced file must respect the DALI 1.0 or TAP Notes 1.0
syntax. No check of the file is performed by the library ; it is up to the
author of the referenced file (a XHTML/RDFa file) to write a correct "examples"
endpoint content. Check out the examples provided on the GitHub repository in
the directory examples/tap/examples_endpoint.
