Hi I want to write a ISBN validation in PLSql. But dbms_output.put_line doesnt output anything. I dont have any errors but dbms_output is yellow marked with the warning:
Unable to resolve symbol 'dbms_output'
Inspection info: This inspection performs unresolved SQL references check.
. Im working in DataGrip and yes I have enabled SYS.dbms_output.
DECLARE
v_isbn VARCHAR(13) := 9783161484100;
BEGIN
isbn_validation(v_isbn);
end;
CREATE OR REPLACE PROCEDURE isbn_validation
(
p_isbn VARCHAR

v_isbn VARCHAR(13);
v_checksum INTEGER := 0;
BEGIN
if LENGTH(p_isbn) = 10 THEN
v_isbn := CONCAT('978',p_isbn);
v_checksum := isbn13_checksum(v_isbn);
if(v_checksum = -1)THEN dbms_output.put_line(v_isbn || ' is a invalid isbn');
else
v_isbn:=CONCAT(v_isbn,CAST(v_checksum AS CHAR));

Try explicitly enabling DBMS_OUTPUT using dbms_output.enable
DECLARE
v_isbn VARCHAR(13) := 9783161484100;
BEGIN
dbms_output.enable;
isbn_validation(v_isbn);
end;
Execute SET SERVEROUTPUT ON and run your code again.

I have assembled a procedure to dump a query containing CLOB columns to a csv file.
It seems to be working fine until I encounter a query containing dates.
ORA-00932: inconsistent datatypes: expected CLOB got DATE
Is there a way to dynamically convert those dates to some default string format to be able to use the procedure as it is now. Or how can I refactor it if necessary?

Found it myself, following this pattern:
-- Define columns
FOR i IN 1 .. colcnt LOOP
IF desctab(i).col_type = 2 THEN
DBMS_SQL.DEFINE_COLUMN(curid, i, numvar);
ELSIF desctab(i).col_type = 12 THEN
DBMS_SQL.DEFINE_COLUMN(curid, i, datevar);
......
ELSE
DBMS_SQL.DEFINE_COLUMN(curid, i, namevar);
END IF;
END LOOP;
I have a value that i dont know exactly in which column it is inserted. I can determine that since this table columns are named as C1....C99. I am going to find the column using the following code. But when the no data found exception is called, I cant start my loop again.
DECLARE
i number:=1;
k boolean := true;
output number;
stmt varchar(500);
BEGIN
<<repeat>>
while(k)
loop
DBMS_OUTPUT.PUT_LINE( 'c column -->'||i );
EXECUTE IMMEDIATE 'select 1 from X_TAB t where t.c'||i||'= ''NOTE_NFE'''
into output;
IF output = 1 then
DBMS_OUTPUT.PUT_LINE( 'c column'||i );
k:=false;
END IF;
i:=i+1;
IF i = 100 then
k:=false;
END IF;
END LOOP;
EXCEPTION
when no_data_found then
i:=i+1;
if i = 100 then
k:=false;
end if;
goto repeat;
END;
/
I think that moving your try catch to inside the loop will do the trick for you.
DECLARE
i number:=1;
k boolean := true;
output number;
stmt varchar(500);
BEGIN
<<repeat>>
while(k)
loop
DBMS_OUTPUT.PUT_LINE( 'c column -->'||i );
begin
EXECUTE IMMEDIATE 'select 1 from X_TAB t where t.c'||i||'= ''FISCAL_NOTE_NFE''' into output;
exception when no_data_found then
output := 0; --set a default value
dbms_output.put_line('no data found.');
end;
IF output = 1 then
DBMS_OUTPUT.PUT_LINE( 'c column'||i );
k:=false;
END IF;
i:=i+1;
IF i = 100 then
k:=false;
END IF;
END LOOP;
END;
/
You can use:
SELECT CASE
WHEN EXISTS (
SELECT 1
FROM X_TAB
WHERE dynamic_column_name = 'FISCAL_NOTE_NFE'
)
THEN 1
ELSE 0
END
FROM DUAL
It will never throw the exception as it will always return exactly one row.
You can use it like:
DECLARE
i INT := 0;
output INT;
BEGIN
FOR k IN 1 .. 100 LOOP
DBMS_OUTPUT.PUT_LINE( 'c column -->'||k );
EXECUTE IMMEDIATE 'SELECT CASE WHEN EXISTS(SELECT 1 FROM X_TAB WHERE c'||k||' = ''FISCAL_NOTE_NFE'') THEN 1 ELSE 0 END FROM DUAL'
INTO output;
IF output = 1 THEN
DBMS_OUTPUT.PUT_LINE( 'c column'||k );
i := k;
EXIT;
END IF;
END LOOP;
-- Do something with i
END;
/
You can also use
select count(1) from X_TAB

This is a screenshot of the error message that displays to one of the users whilst the other user sees Operation successful.
You will get that error if your C2 cursor doesn't find anything; the CLOB is never opened because you don't go into the loop, but you still do the dbms_lob.close, and that will throw that ORA-22275 error:
DECLARE
key_all_data CLOB;
BEGIN
dbms_lob.close(key_all_data);
END;
/
ORA-06502: PL/SQL: numeric or value error: invalid LOB locator specified: ORA-22275
You don't really need to open your temporary CLOB, which means you don't need to close it either; but you should free it either way. So you can remove the line:
dbms_lob.open(key_all_data, 1);
and change:
dbms_lob.close(key_all_data);
to:
if dbms_lob.istemporary(key_all_data) = 1 then
dbms_lob.freetemporary(key_all_data);
end if;
If you want to keep the open then test the close part too:
if dbms_lob.istemporary(key_all_data) = 1 then
if dbms_lob.isopen(key_all_data) = 1 then
dbms_lob.close(key_all_data);
end if;
dbms_lob.freetemporary(key_all_data);
end if;
You might think that if you you have created the temporary CLOB and opened it then it will be open and therefore can be closed; but this:
key_all_data := replace(...);
... is replacing one temporary CLOB with another, which is not explicitly open. You can look at the istemporary and isopen values to see what is happening. You could look at dbms_lob.fragment_replace etc. instead, or skip the open/close and don't worry about it...
It isn't clear if one call to this procedure is changing what the next call sees in the cursor (since the update doesn't seem to do anything) but the form or something this calls might be doing more work that does.
There are probably lots of other issues and comments - exception when others then null jumps out as a really bad idea - but they're getting a bit off-topic.
I think that you are trying append null values to clob variable.
declare
key_all_data clob := 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa';
v varchar2(10);
begin
begin
dbms_lob.append(key_all_data,v); -- exception
