Server Command Options • --symbolic-links ,  --skip-symbolic-links • --sysdate-is-now • --tc-heuristic-recover={COMMIT|ROLLBACK} 756 SYSDATE()  by default returns the time at which it executes, not the time at which the statement in which it occurs begins executing. This differs from the behavior of  NOW() . This option causes  SYSDATE()  to be a synonym for  NOW() . For information about the implications for binary logging and replication, see the description for  SYSDATE()  in Section 12.7, “Date and Time Functions”  and for  SET TIMESTAMP  in Section 5.1.8, “Server System Variables” . This option has no meaning on Windows. Symbolic link support, along with the  --symbolic-links  option that controls it, is deprecated; you should expect it to be removed in a future version of MySQL. In addition, the option is disabled by default. The related  have_symlink  system variable also is deprecated; expect it be removed in a future version of MySQL. Enable or disable symbolic link support. On Unix, enabling symbolic links means that you can link a MyISAM  index file or data file to another directory with the  INDEX DIRECTORY  or  DATA DIRECTORY option of the  CREATE TABLE  statement. If you delete or rename the table, the files that its symbolic links point to also are deleted or renamed. See Section 8.12.2.2, “Using Symbolic Links for MyISAM Tables on Unix” .
