This commit introduces additional tests for "quoted identifier" support
in SimpleJdbcInsert when the schema itself is defined using quoted
identifiers -- for example, to use keywords as column names.
See gh-31208
This commit introduces initialize() methods in
AbstractRoutingDataSource and AbstractRoutingConnectionFactory as an
alternative to invoking afterPropertiesSet().
Closes gh-31248
Prior to this commit, DefaultJdbcClient updated the supplied KeyHolder
when using named parameters but not for positional parameters.
This commit refactors the creation of the
PreparedStatementCreatorFactory so that the PreparedStatementCreator
properly creates a PreparedStatement which returns generated keys.
Closes gh-31297
Prior to this commit, when using RowCallbackHandler or ResultSetExtractor in JdbcClient
and passing a parameter to paramSource(), an exception was thrown stating "No value
supplied for the SQL parameter 'xxxxxx'" because the SqlParameterSource used internally
was the wrong one.
Closes gh-31195
Prior to this commit, the withoutTableColumnMetaDataAccess() and
includeSynonymsForTableColumnMetaData() methods in SimpleJdbcInsert
incorrectly declared a SimpleJdbcInsertOperations return type, which
prevented method chaining when the instance was declared to be of type
SimpleJdbcInsert.
This commit changes the return types of those methods to
SimpleJdbcInsert to benefit from covariant return types like the rest
of the configuration methods in SimpleJdbcInsert.
Closes gh-31177
Prior to this commit and the previous commit, SimpleJdbcInsert did not
provide built-in support for "quoted identifiers". Consequently, if any
column names conflicted with keywords or functions from the underlying
database, you had to manually quote the column names when specifying
them via `usingColumns(...)`, and there was unfortunately no way to
quote schema and table names.
The previous commit provided rudimentary support for quoted SQL
identifiers (schema, table, and column names) by querying
java.sql.DatabaseMetaData.getIdentifierQuoteString() to determine the
quote string. It also introduced `usingEscaping(boolean)` in
`SimpleJdbcInsertOperations` to enable the feature. However, it
incorrectly quoted the schema and table names together, and it did not
take into account the fact that a quoted identifier should respect the
casing (uppercase vs. lowercase) of the underlying database's metadata.
This commit revises quoted identifier support in `SimpleJdbcInsert` by:
- renaming `usingEscaping(boolean)` to `usingQuotedIdentifiers()`
- quoting schema and table names separately
- respecting the casing (uppercase vs. lowercase) of the underlying
database's metadata when quoting identifiers
- introducing integration tests against an in-memory H2 database
