I'm running Oracle Database 11g Express Edition Release 11.2.0.2.0 - 64bit Production, and I'm trying to convert a few hex characters to a string:
SQL> select hextoraw('414243') from dual;
HEXTOR
------
414243
But it seems nothing has been done here, am I miss understanding this macro?
Because the tools displays the result as string, so it seems nothing changed. Actually the datatypes are different, please use below SQL to check:
SQL> SELECT DUMP('414243'),DUMP(HEXTORAW('414243')) from dual
A B
-------------------------------- --------------------------------------
Typ=96 Len=6: 52,49,52,50,52,51 Typ=23 Len=3: 65,66,67
I believe SQL*Plus is just formatting the RAW to a format convenient for display.
HEXTORAW('414243') converts your string to the RAW(3) consisting of [0x41 0x42 0x43]. Then, when sqlplus tries to display that value back to the user, it converts it to something it can print to the terminal.
Here is a SQL Fiddle, but it looks like it displays the RAW value in base-10 format rather than hex. I'm not sure if there is a format command for sqlplus to change this behavior.
select hextoraw( '414243' ) as col1,
utl_raw.cast_to_varchar2( hextoraw( '414243' )) as col2
from dual;
| COL1 | COL2 |
|----------|------|
| 65,66,67 | ABC |

I am using the oracle version.
Oracle Database 11g Release 11.2.0.1.0
I accidentally ran the command o; in oracle delveloper.
The result is as below.
The PL/SQL procedure completed successfully.
not spooling currently
The sqlcl_int_runme alias has been removed.
I don't know what I did....
First of all, there seems to be no problem with basic table CRUD.
Has anyone had this experience?
I need an explanation of what happened...
It's an alias.
We copied over some popular commands from postgresql to SQLcl, one of those was 'o'
From the post docs
\o or \out [ filename ] \o or \out [ |command ] Arranges to save
future query results to the file filename or pipe future results to
the shell command command. If no argument is specified, the query
output is reset to the standard output.
If the argument begins with |, then the entire remainder of the line
is taken to be the command to execute, and neither variable
interpolation nor backquote expansion are performed in it. The rest of
the line is simply passed literally to the shell.
“Query results” includes all tables, command responses, and notices
obtained from the database server, as well as output of various
backslash commands that query the database (such as \d); but not error
messages.

I have an Oracle 12c database that is replacing £ with ?? on INSERT. The insert is coming from a 11.2 instant client SQL*Plus session. Both boxes are running Linux.
The same also happens from SQL*Plus on the DB host itself.
The DB host has the following settings:
$LANG: en_GB.UTF8
NLS_CHARACTERSET: AL32UTF8
The Client has:
$LANG: en_GB.UTF-8
$NLS_LANG is not set for either DB or Client hosts.
select dump('£', 1017) from dual;
DUMP('??',1017)
-----------------------------------------------------
Typ=96 Len=6 CharacterSet=AL32UTF8: ef,bf,bd,ef,bf,bd
EDIT: Correction. Only £ is being replaced, but is being replaced with ??
You are seeing the Unicode replacement character. It looks like your Linux environment setting for the Oracle NLS_LANG variable is not appropriate:
$ export NLS_LANG="ENGLISH_UNITED KINGDOM.US7ASCII"
$ sqlplus ...
SQL> select dump('£', 1017) from dual;
DUMP('??',1017)
-----------------------------------------------------
Typ=96 Len=6 CharacterSet=AL32UTF8: ef,bf,bd,ef,bf,bd
With a setting that matches your LANG it works as expected:
$ export NLS_LANG="ENGLISH_UNITED KINGDOM.AL32UTF8"
$ sqlplus ...
SQL> select dump('£', 1017) from dual;
DUMP('£',1017)
-----------------------------------------
Typ=96 Len=2 CharacterSet=AL32UTF8: c2,a3
which is the Unicode pound sign.
Updating my question:
When I run this query from unix using sqplus it gives me duplicate outputs
Query:
select sysdate from dual
/
/*comment*/
EXIT
Output
SQL> #tt.sql
12-AUG-16
12-AUG-16
Here is what is happening.
The first two lines (including the /) form a complete SQL statement. SQLPlus executes it and displays the first line.
Then /*comment*/ is OUTSIDE the SQL statement. So it is interpreted by SQLPlus, not as a SQL comment.
The point is, comments in the SQLPlus scripting language have a different syntax; they are lines that begin with REM[ARK]. /*comment*/ is NOT a comment in SQLPlus.
Instead, in SQLPlus, a slash / as the first character on a new line means repeat the last SQL command (if after that you had SQLPlus commands, like DESCRIBE or COLUMN, those are ignored). Everything AFTER the slash is ignored. To convince yourself of this, try again, but with the comment line changed to /*comment* (delete the second slash). You will see the same result.
Then you have the command EXIT, but since it is NOT followed by a slash, it is not seen as a completed command. If I copy and paste your code in my SQLPlus window, I get the screenshot below. However, if at this point you press ENTER (or if this was in a sql script and not copied and pasted from a text editor), the SQLPlus window would shut down.
Hope this helps!

What is the best way to pass multiple values from one variable into separate records in an oracle db?
I want to take the output from:
hddlist=`iostat -Dl|awk '{print ""$1"="$(NF)}'
This returns output like this:
hdisk36=0.8
hdisk37=0.8
hdisk38=0.8
hdisk40=5.5
hdisk52=4.9
I want to insert them into a database like so:
sqlplus -s /nolog <<EOF1
connect / as sysdba
set verify off
insert into my_table ##Single Record Here
EOF1
How can I systematically separate out the values so i can create individual records that look like this:
Disk Value
--------- -------
hdisk36 0.8
hdisk37 0.8
hdisk38 0.8
hdisk40 5.5
hdisk52 4.9
I originally tried a while loop with a counter but could not seem to get it to work. An exact solution would be nice but some directional advice would be just as helpful.
Loop and generate insert statements.
sql=$(iostat -Dl | awk '{print ""$1"="$(NF)}' | while IFS== read -r k v ; do
printf 'insert into mytable (k, v) values (%s, %s);\n' "$k" "$v"
done)
This output can be passed in some manner to sqlplus, perhaps like this
sqlplus -s /nolog <<EOF1
connect / as sysdba
set verify off
$sql
EOF1
Although, depending on the line format of iostat, it might be simpler to just omit awk and parse with read directly.
You can redirect the output to a file and then use an external table
It should look something like this:
CREATE TABLE hddlist_ext_table (
disk CHAR(16),
value CHAR(3)
ORGANIZATION EXTERNAL (
TYPE ORACLE_LOADER DEFAULT DIRECTORY tab_dir
ACCESS PARAMETERS (RECORDS DELIMITED BY NEWLINE
FIELDS TERMINATED BY '=')
LOCATION ('your_file_name'));
Then you can either use this table for your data or insert-select from it to your table;
insert into my_table
select disk, value from hddlist_ext_table;
You can insert multiple rows in a single SQL statement in Oracle like this
INSERT ALL
INTO mytable (column1, column2, column3) VALUES ('val1.1', 'val1.2', 'val1.3')
INTO mytable (column1, column2, column3) VALUES ('val2.1', 'val2.2', 'val2.3')
INTO mytable (column1, column2, column3) VALUES ('val3.1', 'val3.2', 'val3.3')
SELECT * FROM dual;
If you intend to run this script automatically at intervals to then see the results of each disk, you will probably need additional columns to hold the date and time.
You might also look at sqlldr as you can specify a control file telling it what your data contains and then this will load the data into a table. It is more suited to the purpose if you are loading lots of data than SQL Plus.
Got problem with executing my script under SQLPLUS. Under SQL Developer it works well.
set serveroutput on size 1000000

yyy := 'XxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzzXxxYyyZzz';

dbms_output.put_line(yyy);
end;

Under SQLPLUS I get error:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error ORA-06512: at line 1
Any solution how to force running scripts with long output under SQLPLUS? I need output on because I spool results to file.
You are using a Oracle client older than Oracle 10g against an Oracle 10g Database
Please find the quote from ASKTOM below
The problem is NOT during runtime, you are apparently using an old client against a 10.2 or above database. The database code runs fine
It is when the client goes to PICK UP THE STRING from the database that you are hitting the exception.
sqlplus is doing something like this:
a) call procedure/code - it runs and fills a dbms_output buffer, an array in a package.
b) then sqlplus calls dbms_output.GET_LINES to get the buffered output to print. THIS is the call that fails.
