sqlpp::optional is an alias for std::optional for C++17 and beyond.
Otherwise, it is a simple and incomplete backport.
For older versions of C++, the library offers simple back
Similar for string_view and span.
Before this change, sqlite3::connection::execute silently
ignores statements after the first one (separated by semicolon).
After this change, trailing statements are detected and an
sqlpp::exception is thrown.
This change also adds documentation to other connectors indicating
that execute is supposed to be used with single statements only,
even though it is possible to do otherwise.
* Document the connector API method is_transaction_active()
* Move mysql::connection_base::is_transaction_active() to the other transaction-handling methods.
* Add more tests for mysql::connection::is_transaction_active()
* Add postgresql::connection_base::is_transaction_active()
* Add tests for postgresql::connection_base::is_transaction_active()
* Change the type of the SQLite3 transaction status from transaction_status_type to a boolean flag.
* Add sqlite3::connection_base::is_transaction_active()
* Add tests for sqlite3::connection_base::is_transaction_active()
* When closing a transaction do it in the following order: report (if any), execute SQL command, set transaction active flag to false.
* Replace connection handle method check_connection() with is_connected() and ping_server()
* When a connections is fetched from a pool perform a validity check which can be one of none, passive or ping.
* Add the methods is_connected() and ping_server() to the connection template class.
* Remove unused #include and add mising #include.
* Add tests for the connection methods is_connected() and ping_server().
Add support for connection pooling
* Add support for connection pooling to the core code.
* Add support for PostgreSQL connection pooling with tests.
* Add support for SQLite3 connection pooling with tests.
* Add support for MySQL connection pooling with tests.
Leak: The sqlite3 connection handle destructor was
accidentally turned into a default constructor during the
migration of repositories.
Replaced the sqlite3 raw pointer with a unique_ptr to prevent
this kind of accident.
Add Connector Cmake logic
* Also install date when used with fetch content
* Install everything always
* Update documentation
* Add option to control dependency searching
* Adjust travis
Changed sqlite3 usage tests to be linked into one executable.
This provokes multiple definition errors for non-inlined free
functions.
Also ran clang-format on the changed headers.
