表的行數

獲取Firebird所有表及每個表中記錄的總行數
通過sql獲取，直接在FlameRobin中的查詢視窗執行

set term !! ;
EXECUTE BLOCK 
returns ( stm varchar(60), cnt integer )
as
BEGIN
for select cast('select count(*) from "'||trim(r.RDB$RELATION_NAME)||'"' as varchar(60))
from RDB$RELATIONS r
where (r.RDB$SYSTEM_FLAG is null or r.RDB$SYSTEM_FLAG = 0) and r.RDB$VIEW_BLR is null
order by 1
into :stm
DO
BEGIN
execute statement :stm into :cnt;
suspend;
END
END
 

表的物理大小

沒有找到資料字典，不能通過簡單的sql語句獲取相應的資訊。
可以通過Firebird server版自帶的 gstat 命令獲取data pages，只能估算表的大小，不精確。
如果有其它方式，請留言漲姿勢～
windows 7下gstat使用範例

1. 進到firebird安裝目錄的bin資料夾下，應該可以找到gstat.exe
   bin
2. shift + left click 開啟cmd視窗
3. 執行命令

   gstat c:\sample.GDB -u sysdba -p masterkey -d > statics_data.gst 
   

4. 在bin目錄下可以得到檔案 statics_database.gst
5. 檔案示例
