HP-UX平台的 EXPDP 转义符定义 FLASHBACK_TIME

同事在HP-UX平台执行EXPDP导出时遇到错误，问我哪些转义符需要定义，导出命令大致是这样的：
HP> expdp eygle SCHEMAS=eygle DIRECTORY=data_pump_dir DUMPFILE=eygle.dmp FLASHBACK_TIME=\"TO_TIMESTAMP('31-12-2010 11:30:30', 'DD-MM-YYYY HH24:MI:SS')\"
Badly placed ()'s.

这里只转义双引号还不够，括号也是特殊字符，需要转义：
 expdp eygle/eygle DIRECTORY=data_pump_dir FLASHBACK_TIME=\"TO_TIMESTAMP\('31-12-2010 11:30:30', 'DD-MM-YYYY HH24:MI:SS'\)\"
