使用存储过程批量查询ArcSDE要素类及索引的存储大小
查询SQL语句参考：http://blog.csdn.net/linghe301/article/details/6331329
其实这个很简单，如果想解决需要掌握三个条件
1：Oracle基础知识
2：ArcSDE表结构知识
3：PL/SQL编程
下面是创建一个批量查看存储ArcSDE要素类以及其SIZE的存储过程
create or replace procedure DisplayFeatureClassSize is
--定义查询要素类游标
type sp_fc_cursor is ref cursor;
--定义查询要素类Byte游标
type sp_fc_byte_cursor is ref cursor;
--要素类游标对象
fc_cursor sp_fc_cursor;
--要素类Byte游标对象
fc_byte_cursor sp_fc_byte_cursor;
--要素类
fc sde.table_registry.table_name%type;
--要素类bytes
fc_bytes user_segments.bytes%type;
begin
open fc_cursor for select table_name from sde.table_registry where config_keyword='DEFAULTS' order by table_name;
--循环要素类
loop
fetch fc_cursor into fc;
exit when fc_cursor%notfound;
open fc_byte_cursor for select bytes/1024 from user_segments where segment_type='TABLE' and segment_name=fc;
--循环要素类对应的bytes
loop
fetch fc_byte_cursor into fc_bytes;
--如果要素类为空，那么在user_segments表里面是没有任何记录信息的
exit when fc_byte_cursor%notfound;
dbms_output.put_line('FetureClass：'||fc||' Size：'||fc_bytes||'KB');
end loop;
end loop;
exception
when no_data_found then
dbms_output.put_line('Error');
close fc_cursor;
end;
简单的PL/SQL编程提示
--显示执行结果 set serveroutput on --查看错误 show errors
我们查看一下执行结果
SQL> exec DisplayFeatureClassSize FetureClass:AAA Size:512KB FetureClass:AAABB Size:512KB FetureClass:AMD_ZWMD_ART Size:512KB FetureClass:AMD_ZWMD_BND Size:512KB FetureClass:AMD_ZWMD_CAT Size:512KB FetureClass:AMD_ZWMD_LOG Size:512KB FetureClass:ATLANTIC Size:512KB FetureClass:BB Size:14336KB FetureClass:DDD Size:58368KB FetureClass:DLBT Size:1024KB FetureClass:DLTB1 Size:1024KB FetureClass:DLTB2 Size:1024KB FetureClass:EXPORT Size:512KB FetureClass:G_TEST1_NET_JUNCTIONS Size:512KB FetureClass:HS Size:2560KB FetureClass:KZBJBJ Size:512KB FetureClass:LZ_FH_YT_PL Size:154624KB FetureClass:OWNER Size:512KB FetureClass:PLACE Size:512KB FetureClass:POLYGON Size:512KB FetureClass:QUXIAN Size:512KB FetureClass:QZPOI4 Size:2048KB FetureClass:QZPOI4_1 Size:2048KB FetureClass:QZPOI4_2 Size:2048KB FetureClass:RANDOMCRIMEPOINTS_COPYROWS Size:7168KB FetureClass:RES2_4M Size:512KB FetureClass:RES2_4MANNO Size:512KB FetureClass:RES2_4MANNO2 Size:512KB FetureClass:ROAD Size:1536KB FetureClass:T1_LINE Size:512KB FetureClass:XIAN Size:512KB FetureClass:XZQH Size:512KB PL/SQL procedure successfully completed
说明一下：我的数据比较特殊，就是我的数据都在SDE表空间或者说SDE用户下存储，但是如果用户是在其他用户存储，可能就需要修改一下了，自己发挥吧。
下面是我们查询要素类所对应空间索引的大小
create or replace procedure DisplayFeatureClassIndexSize is
--定义查询要素类游标
type sp_fc_cursor is ref cursor;
--定义查询要素类索引Byte游标
type sp_fc_indexbyte_cursor is ref cursor;
--要素类游标对象
fc_cursor sp_fc_cursor;
--要素索引Byte游标对象
fc_indexbyte_cursor sp_fc_indexbyte_cursor;
--要素类
fc sde.st_geometry_index.table_name%type;
--IndexID
fc_indexid sde.st_geometry_index.index_id%type;
--要素类索引bytes
fc_indexbytes user_segments.bytes%type;
test user_segments.segment_name%type;
begin
open fc_cursor for select table_name,index_id from sde.st_geometry_index order by table_name;
--循环要素类
loop
fetch fc_cursor into fc,fc_indexid;
exit when fc_cursor%notfound;
test:='S'||fc_indexid||'$_IX1';
open fc_indexbyte_cursor for select bytes/1024 from user_segments where segment_type='INDEX' and segment_name=test;
--循环要素类对应的bytes
loop
fetch fc_indexbyte_cursor into fc_indexbytes;
--如果索引信息为空，那么在user_segments表里面是没有任何记录信息的
exit when fc_indexbyte_cursor%notfound;
dbms_output.put_line('FetureClass：'||fc||' IndexSize：'||fc_indexbytes||'KB');
end loop;
end loop;
exception
when no_data_found then
dbms_output.put_line('Error');
close fc_cursor;
end;
