我有一個表NEW_TABLEID和ORA_GEOMETRY如何更新或插入MDSYS.SDO_GEOMETRY多個多邊形

其中id = 1然後

ORA_GEOMETRY = MDSYS.SDO_GEOMETRY(2003, 32638, null, MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 1), MDSYS.SDO_ORDINATE_ARRAY(462897.8239, 4551252.4903, 462869.6794, 4551237.1391, 462821.0656, 4551321.5734, 462770.4983, 4551381.3337, 462764.7756, 4551388.0969, 462754.1560, 4551377.4776, 462741.7481, 4551365.07, 462741.7481, 4551363.7611, 462741.7474, 4551329.2490, 462764.7750, 4551290.8697, 462808.2715, 4551232.0215, 462821.0646, 4551201.3181, 462803.1544, 4551183.4076, 462757.10, 4551173.1735, 462747.3533, 4551152.4610, 462764.0828, 4551144.0964, 462767.3352, 4551142.4702, 462780.1283, 4551122.0012, 462785.2455, 4551093.8564, 462785.2455, 4551032.4494, 462790.3627, 4550930.1047, 462823.6248, 4550861.0220, 462850.7758, 4550815.7704, 462849.2111, 4550881.4909, 462826.1833, 4551001.7460, 462826.1833, 4551065.7114, 462826.1833, 4551132.2357, 462844.0938, 4551145.0287, 462854.3284, 4551083.6219, 462867.1215, 4550983.8357, 462879.9146, 4550863.5805, 462885.0318, 4550812.4081, 462882.4728, 4550727.9744, 462869.6799, 4550633.3048, 462844.0937, 4550513.0495, 462795.4799, 4550446.5256, 462770.4995, 4550405.3075, 462775.6698, 4550405.3077, 462795.8360, 4550409.5531, 462802.7176, 4550412.9935, 462812.8183, 4550418.0442, 462829.8008, 4550425.4738, 462842.5375, 4550429.7193, 462853.1510, 4550429.7193, 462864.8268, 4550426.5353, 462879.6863, 4550415.9213, 462886.6694, 4550410.2476, 462946.4704, 4550462.0752, 462920.8524, 4550490.0220, 462915.7352, 4550538.6358, 462925.9698, 4550561.6634, 462959.2317, 4550561.6634, 462983.6238, 4550561.6634, 462972.0247, 4550648.6564, 462954.1144, 4550707.5047, 462931.0868, 4550776.5875, 462918.2937,

及其繪製一個多邊形

其中id = 2那麼

這輪到了一個多邊形。

我想這兩條線合併成一個，所以如果我看着它，我展示兩個多邊形其中id = 3

假設你的表是這樣的：

create table new_table (
    id number, 
    ora_geometry sdo_geometry

，人口這樣

insert into new_table (id,ora_geometry)

要插入一個新的多邊形是前兩個的結合，這樣做：

insert into new_table (id, ora_geometry) 
select 3, sdo_aggr_union (sdoaggrtype(ora_geometry, 0.0005)) 
from new_table 
where id in (1,2); 
commit;

請注意，這不必然產生相同的結果作爲第一個答案手動工會：

這是因爲工會聚集不定義在它組裝多邊形的順序。多邊形中多邊形的順序並不重要。

您可以將兩個多邊形存儲到一個多面SDO_GEOMETRY對象。

這是2007年型

的elem_info_array限定了縱軸形成各個多邊形。一個多邊形由縱座標開始於位置1，另一個開始於位置123.因此，mdsys.sdo_elem_info_array(1, 1003, 1, 123, 1003, 1)

另請參閱文檔。

最後我加了驗證，看看這實際上導致了有效的幾何。

希望這回答你的問題。
