afc619f0a2 WorkLog#1280 - Remove fixed table handler from lex/yacc 2003-12-02 20:23:13 +00:00
monty@mysql.com
7c6113a39f Merge key cache structures to one 
Fixed compiler warnings (IRIX C compiler and VC++)

cab1dc628c CLIENT_MULTI_QUERIES -> CLIENT_MULTI_STATEMENTS 
New multi-key-cache handling. This was needed becasue the old one didn't work reliable with MERGE tables.
ALTER TABLE table_name ... CHARACTER SET  ... now changes all char/varchar/text columns to the given character set
(One must use ALTER TABLE ... DEFAULT CHARACTER SET ... to change the default character set)
Fixed that have_compress is detected properly (fixes problems with func_compress.test on platforms without zlib)
New syntax for CACHE INDEX ('keys' is optional if no index name is given and one mentions the key cache name only ones)
Removed compiler warnings
Added mysql_set_server_option() to allow clients like PHP to easaily set/reset the multi-statement flag.
