SQL: Enforce and document dedicated client version compatibility (#70451) (#70624)
* Implement dedicated client version compatibility

Add further dedicated client (xDBC, CLI) compatibility rules and
document these. A client is version-compatible with the server if:
- it supports version compatibility (past or on 7.7.0); and
- it's not on a version newer than server's; and
- it's major version is at most one unit behind server's.

SQL: Test and fix the NULL handling of the String functions (#68379) (#68684)
Fixed the inconsistencies regarding NULL argument handling.
NULL literal vs NULL field value as function arguments in some case
resulted in different function return values.

Functions should return with the same value no matter if the argument(s)
came from a field or from a literal.

The introduced integration test tests if function calls with same
argument values (regardless of literal/field) will return with the
same output (also checks if newly added functions are added to the
testcases).

Fixed the following functions:
* Insert: NULL start, length and replacement arguments (as fields) also
result in NULL return value instead of returning the input.
* Locate: NULL pattern results in NULL return value, NULL optional start
argument handled the same as missing start argument
* Replace: NULL pattern and replacement results in NULL instead of
returning the input
* Substring: NULL start or length results in NULL instead of returning
the input

Fixes #58907

QL: Implement support for date_nanos ES type. (#67666) (#68198)
* QL: Implement support for date_nanos ES type. (#67666)

Use an internal new DataType DATETIME_NANOS which is not exposed
and therefore cannot be used for CASTing. DATETIME is used instead
and the precision of both DATETIME and TIME has been promoted from
3 to 9, providing transparency to all datetime functionality regardless
of millis or nanos precision.

Moreover, CURRENT_TIMESTAMP/CURRENT_TIME can now return precision up
to 6 fractional digits of a second with the use of Clock.

cc3a68730d Abort sorting in case of local agg sort queue overflow (#65687)
In case the local agg sorter queue gets full and no limit has been provided,
the local sorter will now erroneously call the failure callback for every
single row in the original rowset that's left over the local queue limit
(instead for just the first one).  The failure response is dispatched in any
case, so this is relatively harmless.  The sorter continues iterating on the
original response fetching subsequent pages. In case of correct Elasticsearch
behaviour, this is also harmless, it'll just trigger a number of internal
exceptions. However, in case of a pagination defect in Elasticsearch (like
GH#65685, where the same search_after is returned), this will result in an
effective spin loop, potentially rendering eventually the node unresponsive.

This PR simply breaks both the inner loop iterating over the current unsorted
rowset, as well as the outer one, iterating over the left pages.

It also fixes an outdated documentation limitation.

3c9f183447 SQL: Escaped wildcard (*) not accepted in LIKE (#63428)
For a query like `SELECT name FROM test WHERE name LIKE ''%c*'` ES SQL
generates an error. `*` is not a special character in a `LIKE` construct
and it's expected to not needing to be escaped, so the previous query
should work as is.
In the LIKE pattern any `*` character was treated as invalid character
and the usage of `%` or `_` was suggested instead. But `*` is a valid,
acceptable non-wildcard on the right side of the `LIKE` operator.

SQL: Add option to provide the delimiter for the CSV format (#59907) (#60420)
* SQL: Add option to provide the delimiter for the CSV format (#59907)

* Add option to provide the delimiter to the CSV fmt

This adds the option to provide the desired character as the separator
for the CSV format (the default remains comma).
A set of characters are excluded though - like CR, LF, `"` - to avoid
slipping onto the CSV-dialects slope. The tab is also forbidden, the
user needs to choose the "tsv" format explicitely.

Update the doc to make it clear that the textual CSV, TSV and TXT
formats pass the cursor back to the user through the Cursor HTTP header.

[7.x] SQL: fix handling of escaped chars in JDBC connection string (#58429) (#58977)
SQL: fix handling of escaped chars in JDBC connection string (#58429)

This commit fixes an issue emerging when the connection string URI
contains escaped characters.

The original URI is pre-parsed in order to re-assemble a new URI having
the optional elements filled in with defaults. The new URI has been
using however the unescaped query and fragment parts. So if these
contained any escaped `&` or `=` (such as in the password option value),
the unescaping would reveal them and make them later interfere with the
options parsing.

The commit changes that, so that the new URI be built from the unescaped
"raw" parts of the original URI.

SQL: [Tests] Move JDBC integration tests to new module (#56872) (#57072)
Move the JDBC functionality integration tests from `:sql:qa` to a separate
module `:sql:qa:jdbc`. This way the tests are isolated from the rest of the
integration tests and they only depend to the `:sql:jdbc` module, thus
removing the danger of accidentally pulling in some dependency that may
hide bugs.

Moreover this is a preparation for #56722, so that we can run those tests
between different JDBC and ES node versions and ensure forward
compatibility.

Move the rest of existing tests inside a new `:sql:qa:server` project, so that
the `:sql:qa` becomes the parent project for both and one can run all the integration
tests by using this parent project.

SQL: Fix DATETIME_PARSE behaviour regarding timezones (#56158) (#56182)
Previously, when the timezone was missing from the datetime string
and the pattern, UTC was used, instead of the session defined timezone.
Moreover, if a timezone was included in the datetime string and the
pattern then this timezone was used. To have a consistent behaviour
the resulting datetime will always be converted to the session defined
timezone, e.g.:
```
SELECT DATETIME_PARSE('2020-05-04 10:20:30.123 +02:00', 'HH:mm:ss dd/MM/uuuu VV') AS datetime;
```
with `time_zone` set to `-03:00` will result in

SQL: Implement scripting inside aggs (#55241) (#55371)
Implement the use of scalar functions inside aggregate functions.
This allows for complex expressions inside aggregations, with or without
GROUBY as well as with or without a HAVING clause. e.g.:

```
SELECT MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) AS max, b
FROM test
GROUP BY b
HAVING MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) > 5
```

Scalar functions are still not allowed for `KURTOSIS` and `SKEWNESS` as
this is currently not implemented on the ElasticSearch side.
