sybase 資料庫狀態判斷
| 由於資料庫較多,想通過查詢某個系統表來得知資料庫的情況,如資料庫是否處於線上狀態 我現在是 use xxx/ go 一個個登入試的,感覺比較原始,謝謝. |

sp_helpdb
==============================================================
| 其實很簡單，select status,status2 from master..sysdatabases表，根據andkylee提供的資訊，處理一下，另外你可以參考sybsystemprocs庫中sp_helpdb的原始程式碼，很方便就實現 |
==============================================================
select name,status from sysdatabases
name status
------------------------------ ------
master 0
model 0
sybsystemdb 0
sybsystemprocs 0
tempdb 4
test123 12
test123 中 12代表什麼意思呢？

12=4+8=select into/bulkcopy + truncate log on checkpoint
謝謝，可以說明下 select into/bulkcopy 的意思嗎？
==============================================================
你試下select into或bcp就知道了
