SPROC应该也兼容11g以下的版本。
创建了此过程，但是它为基于多列的索引显示2行。我想将其显示为一行，并用逗号分隔值
当前，如果我在表上执行此操作（以获取索引信息）。它向我显示2行索引（多列），但我希望每个索引仅返回一行。如果有多列，则INDEX_KEYS列应将所有列反映为逗号分隔的列表。
CREATE OR REPLACE PROCEDURE test_1 (
p_table_owner IN VARCHAR2,
p_table_name IN VARCHAR2,
p_result OUT SYS_REFCURSOR
)
AS
BEGIN
OPEN p_result FOR
SELECT
index_name,
index_description,
ltrim(sys_connect_by_path(index_keys,','),',') as Index_Keys,
include_cols,
index_filter,
data_compression,
allow_page_locks,
table_name,
index_type
from
(
Select t.*,
row_number() over (partition by INDEX_NAME order by INDEX_NAME) as rn
from
(
SELECT
ON dis.index_owner = di.owner AND
dis.index_name = di.index_name AND
dis.partition_name = dip.partition_name
JOIN dba_ind_columns ci
ON ci.index_owner = di.owner AND
ci.index_name = di.index_name
WHERE
-- di.table_owner = 'CON$' AND
di.table_name = 'CON$' AND
di.partitioned = 'YES' AND
dip.composite = 'YES' ) t
)
where connect_by_isleaf = 1
connect by index_name = prior index_name
and rn = prior rn+1
start with rn =1 ;
End;

请注意，我已将table_name用作'CON$'。用您的table_name替换为我的名字table_name

对使其也适用于10g版本有什么帮助吗？才知道 我们也可能需要它。

使用LISTAGG和GROUP BY：
Oracle设置：
CREATE TABLE table_name (
id NUMBER CONSTRAINT PK_TABLE_NAME__ID PRIMARY KEY,
value NUMBER,
other1 NUMBER,
other2 NUMBER,
CONSTRAINT U_TABLE_NAME__OTHER1_OTHER2 UNIQUE ( other1, other2 )
);
查询：
（注1：dbfiddle不允许访问dba_*表，因此下面的查询使用user_*表，而没有注释掉适用于dba_版本的部分。）< / i>
（注2：在您不同的UNION ed查询的输出之间似乎没有功能上的区别，因此我删除了di.partitioned上的过滤器。如果存在非显而易见的则可以将它们放回去并在外部查询中执行LISTAGG分组。）
select di.index_name as "INDEX_NAME",
CASE WHEN di.index_type='IOT - TOP' THEN 'clustered' ELSE 'nonclustered' END
||
CASE WHEN di.uniqueness = 'UNIQUE' THEN ', unique' END
||
CASE WHEN cons.constraint_type = 'P' THEN ', primary key' END
||
' located on PRIMARY' AS "INDEX_DESCRIPTION",
LISTAGG( ci.column_name, ',' ) WITHIN GROUP ( ORDER BY ci.COLUMN_POSITION ) as "INDEX_KEYS",
null as "INCLUDE_COLS",
null as "INDEX_FILTER",
null as "DATA_COMPRESSION",
null as "ALLOW_PAGE_LOCKS",
di.table_name as "TABLE_NAME",
case
when di.index_type='IOT - TOP'
then 'CLUSTERED'
else 'NONCLUSTERED'
end AS "INDEX_TYPE"
from /*dba*/user_indexes di
INNER JOIN /*dba*/user_constraints cons
ON ( cons.owner = di.table_owner
AND cons.table_name = di.table_name
-- AND cons.index_owner = di.owner
AND cons.index_name = di.index_name
)
join /*dba*/user_ind_columns ci
on ci.index_name = di.index_name
where di.table_name = 'TABLE_NAME'
--and di.table_owner = 'OWNER'
GROUP BY di.table_name, di.index_name, cons.constraint_type, di.uniqueness, di.index_type
输出：
