我在 11.2.0.3 数据库上遇到了一个问题,一个奇怪的查询占了总数据库活动的 47.42%。
该应用程序是使用 Flex 开发的,前端是 Apache Tomcat 6.0.35,Java 版本为 1.6.0_27。
我在几个网站上搜索过,发现其他人有同样的问题,即使在这个网站上(神秘的 SQL 阻止我的存储过程在 ORACLE 上执行),但到目前为止没有找到解决方案:-(
查询是:
SELECT package_name AS procedure_cat,
owner AS procedure_schem,
object_name AS procedure_name,
argument_name AS column_name,
DECODE(position,
0, 5,
DECODE(in_out,
'IN', 1,
'OUT', 4,
'IN/OUT', 2,
0)) AS column_type,
DECODE (data_type,
'CHAR', 1,
'VARCHAR2', 12,
'NUMBER', 3,
'LONG', -1,
'DATE', 91,
'RAW', -3,
'LONG RAW', -4,
'TIMESTAMP', 93,
'TIMESTAMP WITH TIME ZONE', -101,
'TIMESTAMP WITH LOCAL TIME ZONE', -102,
'INTERVAL YEAR TO MONTH', -103,
'INTERVAL DAY TO SECOND', -104,
'BINARY_FLOAT', 100,
'BINARY_DOUBLE', 101,
1111) AS data_type,
DECODE(data_type,
'OBJECT', type_owner || '.' || type_name,
data_type) AS type_name,
DECODE (data_precision,
NULL, data_length,
data_precision) AS precision,
data_length AS length,
data_scale AS scale,
10 AS radix,
1 AS nullable,
NULL AS remarks,
sequence,
overload,
default_value
FROM all_arguments
WHERE owner LIKE :1 ESCAPE '/'
AND object_name LIKE :2 ESCAPE '/'
AND package_name IS NULL
AND (argument_name LIKE :5 ESCAPE '/'
OR (argument_name IS NULL
AND data_type IS NOT NULL))
ORDER BY procedure_schem, procedure_name, overload, sequence
我想知道是否有人找到了解决方案?
