MySQL Caching Limitations

MySQL sets names to lowercase if it is running on Windows, even if you enclose the mixed case string in double quotes. When using MySQL tables as cache targets, either use the TDV browse option to choose the table, or make sure that you assign lowercase names to tables.

The TDV native load option cannot load binary data.

When using MySQL as a cache target, note the data type limitations, by data source, listed in the following table. Also when MySQL 5.5 is the cache target, time and time stamp data types lose precision for milliseconds and other fractional seconds.
