【中文标题】Oracle 存储过程因复杂类型的 clob 而失败，并带有 ORA-22922【英文标题】：Oracle stored procedure fails with clob in complex type with ORA-22922 【发布时间】：2021-10-25 14:21:50 【问题描述】：我有一个包含存储过程和类型定义的包：
CREATE OR REPLACE package sample_pkg
authid definer
as
type r_file_info_type is record
(
id number,
file_data clob
);
procedure clob_test_complex_out
(
i_char_num in number,
o_file_info out sample_pkg.r_file_info_type
);
end;
CREATE OR REPLACE package body sample_pkg
as
procedure clob_test_complex_out
(
i_char_num in number,
o_file_info out sample_pkg.r_file_info_type
)
as
begin
o_file_info.id := i_char_num;
o_file_info.file_data := 'ABCD';
end;
end;
我试图从 Spring Boot 应用程序中调用它

如何在 Spring Boot 中从 Struct 中获取 Oracle Clob 值？
我已经用 Oracle 19c 试过了。
【问题讨论】：
你能显示package和type的定义吗？你发了两次package body....
我已经添加了缺少的包头（包和类型定义）
【参考方案1】：
我可以用普通的JDBC 重现相同的异常
18c Express Edition Release 18.0.0.0.0 and
DriverVersion 12.1.0.2.0
这里是最小的例子
def type_name = "TEST_CLOB_RECORD.R_CLOB_TYPE"
CallableStatement stmt = null
stmt = con.prepareCall(" call TEST_CLOB_RECORD.GET_CLOB_RECORD(?) ")
stmt.registerOutParameter(1, Types.STRUCT, type_name)
stmt.execute()
Struct outStruct = stmt.getObject(1)
println outStruct.class.name
println outStruct.dump()
到这里 OK - getObject 返回 oracle.sql.STRUCT 类，dump() 为
name = TEST_CLOB_RECORD.R_CLOB_TYPE
length = 1
TXT = oracle.sql.CLOB@6df20ade
getAttributes() 返回CLOB 的副本，但对内容的任何访问都会导致ORA-22922
clob = outStruct.getAttributes()[0]
println clob.dump()
println clob.getSubString(1, (int) clob.length())
给予
<oracle.sql.CLOB@4287d447 dbaccess=oracle.jdbc.driver.T4CConnection@22b53226 dbChunkSize=-1 csform=1 isFree=false fromObject=true cachedLengthOfClobInChars=-1 prefetchData=null prefetchDataSize=0 activePrefetch=false dilCharacterSet=null acProxy=null physicalConnection=oracle.jdbc.driver.T4CConnection@22b53226 data=[0, 38, 0, 0, 66, 8, -128, 0, 0, 2, 4, -101, 0, 0, 1, 10, 0, 0, 0, 1, 3, 105, 0, 12, 0, 0, 0, 0, 0, 2, -100, -78, -69, -106, 0, 0, 0, 0, 0, 0]>
Caught: java.sql.SQLException: ORA-22922: Nonexistent LOB Value
所以在这里我建议联系 Oracle 支持并询问解释...（请参阅下面的简化 PL/SQL 代码）
确实有效虽然非常基本的解决方法是在 PL/SQL 块中获取 record 并将 CLOB 作为（附加）返回值传递 -这里的相关人员剪断了
stmt = con.prepareCall("""declare
v_clob_type test_clob_record.r_clob_type;
begin
test_clob_record.get_clob_record(o_clob_type => v_clob_type);
? := v_clob_type.txt;
end;""")
stmt.registerOutParameter(1, OracleTypes.CLOB)
stmt.execute()
def clob = stmt.getClob(1)
PL/SQL 代码
CREATE OR REPLACE package test_clob_record
as
type r_clob_type is record
(
txt clob
);
procedure get_clob_record
(
o_clob_type out test_clob_record.r_clob_type
);
end;
/
CREATE OR REPLACE package body test_clob_record
as
procedure get_clob_record
(
o_clob_type out test_clob_record.r_clob_type
)
as
begin
o_clob_type.txt := cast ('ABCD' as CLOB);
end;
end;
/
【讨论】：
我之前尝试过这种解决方案，但这并不是我真正想要的。我编写了一个生成此代码的工具，因此结构可以位于数组或其他复杂结构中，因此我不能使用这种解决方法。我的同事找到了其他解决方案，如果数据来自表 clob 字段，它似乎正在工作。以上是关于Oracle 存储过程因复杂类型的 clob 而失败，并带有 ORA-22922的主要内容，如果未能解决你的问题，请参考以下文章
oracle中LOBSEGMENT类型存储的clob的内容过大，如何清除clob字段内容。释放表空间！
