Oracle database virtual machine12/6/2023 To work around this issue, Oracle Database uses abbreviated names (short names) internally, but maintains a correspondence between short names and full names (long names). The full name of Java classes and methods usually exceeds the 31 character limit. In previous releases, the maximum length of a SQL identifier or a database schema object name was 31 characters, and all characters must be legal and convertible to the target database character set. The maximum length of a SQL identifier is now 128 characters for Oracle Java Virtual Machine (Oracle JVM). This feature makes it easier to work with JSON documents stored in an Oracle database and to generate JSON documents from relational data. Support for using JSON in a sharded database configuration.A new data guide feature that facilitates understanding of the structure and content of your JSON documents.Support for performing spatial-based queries on JSON documents containing GeoJSON.Support for optimizing the performance for JSON query operations using Oracle Database In-Memory.This includes the ability to make incremental modifications to JSON documents. Support for manipulating JSON documents using PL/SQL.JSON operators are supported in PL/SQL.New capabilities for generating JSON documents directly from SQL queries and PL/SQL data.The JSON search index can now deal with large keys.The JSON search index support range-based searching on numeric values.The JSON search index supports RANGE and LIST partitioned tables.A new, simplified syntax makes it easier to create a JSON search index.JSON path expressions used with JSON_EXISTS condition now support predicates.The JSON path expressions used with simplified syntax for querying JSON now support navigating to specific members of an array.This release incorporates significant support enhancements for storing and querying JavaScript Object Notation (JSON) documents for Oracle Database. Support for ISO, IEC and ANSI SQL standard syntax simplifies application migration to Oracle Database from non-Oracle Database systems that support column-level collation declarations. It enables developers to optimally address applications where only some of the data needs language or region-specific sorting rules. The column-level collation capability simplifies application development and provides greater flexibility for creating applications. The declared collation is automatically applied by all collation-sensitive SQL operations referencing the column. The column-level collation allows you to declare the sort ordering on a column level, using syntax and semantics compatible with the ISO, IEC and ANSI SQL standard. Numerous collations supported by Oracle Database can order strings according to conventions used in dictionaries, names lists and other sorted text written in many languages of the world. Collation (also called sort ordering) determines if a character string equals, precedes or follows another string when the two strings are compared and sorted.
