By swallowing the exception on failing to release a savepoint, we are hiding
client code from database errors that they may need to be aware of or handle.
e.g. if the connection is now dead when trying to release the savepoint, by
swallowing the exception here, client code has no way of knowing this now until
the next operation on the database, which will yield a confusing message about
the problem and obscures where the failure occurred as it will be in a different
part of their code that throws any exception.
Swallowing the exception here is also inconsistent with all the other database
calls in the Transaction Object, where we always raise an exception up and let
client code decide how to handle the error.
Adds support common in other ResultSet implemenatations for qualifying column names with table name to distinguish potentially duplicate column names in a join of two or more tables from one another. The expected format is {table_name}.{column_namne}, where column_name is the actuall designated column name and not the column label.
This commit reverts some null-safety changes which make sense
on main but are too impactful for 6.1.x for Kotlin developers
using -Xjsr305=strict.

This commit documents that an empty list is not guaranteed to be
supported by the database. For example, MySQL and PostgreSQL do not
support `foo in ()`.

Add helpers to CollectionUtils for building HashSets and LinkedHashSets
that can hold an expected number of elements without needing to
resize/rehash.
Closes gh-32291
This commit revisits the improved detection algorithm for stored
procedure as, unfortunately, certain JDBC drivers do not support
the documented pattern for schema and procedure name.
To work around this limitation, this commit applies the escaping of
wildcard characters to the case where multiple procedures have been
found for a given search.
Closes gh-32295
This commit makes sure that content within backticks are skipped
when parsing a SQL statement using NamedParameterUtils. This harmonizes
the current behavior of ignoring special characters that are wrapped
in backticks.
Closes gh-31944
This commit allows EmbeddedDatabaseConfigurer instances to be further
customized if necessary. EmbeddedDatabaseBuilder has a way now to set
a DatabaseConfigurer rather than just a type to provide full control,
or customize an existing supported database type using the new
EmbeddedDatabaseConfigurers#customizeConfigurer callback.
Closes gh-21160
