From 857c7d3972a03cbeebf730d99b924d3710dee6a0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?louiz=E2=80=99?= Date: Tue, 10 Apr 2018 23:33:59 +0200 Subject: Use a different Date data type MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PLEASE backup your database before testing this commit, and report any migration issue. In postgresql, we use timestamp with timezone. In sqlite3 we use REAL (the date is expressed as julianday) This requires a migration of the muclogline_ table: In postgresql it’s pretty simple, we convert all the integer into timestamps With sqlite3, we actually rename the table, create the new one with the correct type, then copy everything to the new table, with a conversion function for the Date_ column, and then we delete the old table. fix #3343 --- src/database/datetime_writer.hpp | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 src/database/datetime_writer.hpp (limited to 'src/database/datetime_writer.hpp') diff --git a/src/database/datetime_writer.hpp b/src/database/datetime_writer.hpp new file mode 100644 index 0000000..b104911 --- /dev/null +++ b/src/database/datetime_writer.hpp @@ -0,0 +1,32 @@ +#pragma once + +#include +#include + +#include +#include +#include + +class DatetimeWriter +{ +public: + DatetimeWriter(DateTime datetime, const DatabaseEngine& engine): + datetime(datetime), + engine(engine) + {} + + long double get_value() const + { + const long double epoch_duration = this->datetime.epoch().count(); + const long double epoch_seconds = epoch_duration / std::chrono::system_clock::period::den; + return this->engine.epoch_to_floating_value(epoch_seconds); + } + std::string escape_param_number(int value) const + { + return this->engine.escape_param_number(value); + } + +private: + const DateTime datetime; + const DatabaseEngine& engine; +}; -- cgit v1.2.3
