tables. This should fix bug MDEV-7343. modified: storage/connect/ha_connect.cc storage/connect/myconn.cpp storage/connect/myconn.h storage/connect/reldef.cpp storage/connect/reldef.h storage/connect/table.cpp storage/connect/tabmysql.cpp storage/connect/xtable.h - Prevent double column evaluation when CONNECT does filtering modified: storage/connect/connect.cc - Export CreateFileMap and CloseMemMap (for OEM tables) modified: storage/connect/maputil.h - Add the compute function to be used on VALUE types. Preserve precision for DOUBLE values. modified: storage/connect/value.cpp storage/connect/value.h - Typo (in preparation to the future JSON table type) modified: storage/connect/ha_connect.cc storage/connect/mycat.cc storage/connect/plgdbsem.h
