Oracle stored procedure fails with clob in complex type with ORA-22922 - oracle

Question

I have a package with a stored procedure and a type definition:
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;
I have tried to call it from a Spring Boot Application
package hu.sample.service

But it fails with ORA-22922 Nonexistent LOB Value error:

How can I get the an Oracle Clob value from a Struct in Spring Boot?
I have tried it with Oracle 19c.

Answer 1

I can reproduce same exception with plain JDBC with
18c Express Edition Release 18.0.0.0.0 and
DriverVersion 12.1.0.2.0
Here the minimal example
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()
Up to here OK - the getObject returns oracle.sql.STRUCT class with the dump() as
name = TEST_CLOB_RECORD.R_CLOB_TYPE
length = 1
TXT = oracle.sql.CLOB#6df20ade
getAttributes() returns a copy of the CLOB, but any access to the content leads to ORA-22922
clob = outStruct.getAttributes()[0]
println clob.dump()
println clob.getSubString(1, (int) clob.length())
Gives
<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
So here I'd recomment to contact Oracle support and ask explanation... (see the simplified PL/SQL code below)
What does work though as very basic workaround is to get the record in a PL/SQL block and pass the CLOB as an (additional) return value - here the relavant snipped
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 Code
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;
