Changes in MySQL Connector/Node.js 8.0.17 (2019-07-22, General Availability)

Functionality Added or Changed

  • Document fields containing arrays can now be indexed by setting array to true in an index fields definition.

  • Added support for the OVERLAPS and NOT OVERLAPS operators; which is equivalent to the SQL JSON_OVERLAPS() function.

    These binary operators are used with a general "expression operator expression" syntax; and the expressions return a JSON array or object. Example usage: [1, 2, 3] overlaps $.list

  • Added support for the utf8mb4_0900_bin collation added in MySQL Server 8.0.17.

  • The bundled file was split and reformatted with some content moved into the new README.txt and files.

Bugs Fixed

  • The SQL CAST function did not work as a valid lookup expression. (Bug #29807792)

  • Added backtick support for table column identifiers in valid expressions. (Bug #29789818)

  • The DIV binary and NOT unary operators are now allowed; and are case-insensitive. (Bug #29771833, Bug #29771027)

  • Collection.find() now supports the JavaScript Date type. (Bug #29766014)

  • The collection.dropIndex method now silently fails if the index does not exist, as expected, when before it generated a "Can't DROP" error. (Bug #29765589)

  • Column.getCollationName() would potentially return the incorrect name. (Bug #29704185)
