i am designing a database in oracle 11g. I have designed a table with fields,
CUST_ID, NUMBER(5) //this is a foreign key
Review, BLOB //to store big strings
Date, SYSDATE
now when i'm trying to insert data in the table like-
insert into "ReviewTable" values ( 3, 'hello, this is the first review',SYSDATE)
it gives [Err] ORA-01465: invalid hex number.
If someone can help me with the error?
you cast your string into BLOB, you can do this via package utl_raw.cast_to_raw or convert varchar to clob via to_clob('mystring') and then use procedure DBMS_LOB.convertToBlob in your code
but if you are going to use the fields for string why don`t save them as a CLOB?
Here are 2 examples below with BLOB and CLOB fields
BLOB
create table ReviewTable( CUST_ID NUMBER(5)
,Review BLOB
,Dt Date);
insert into ReviewTable values ( 3, utl_raw.cast_to_raw('hello, this is the first review'),SYSDATE);
CLOB
create table ReviewTable2( CUST_ID NUMBER(5)
,Review CLOB
,Dt Date);
insert into ReviewTable2 values ( 3, 'hello, this is the first review',SYSDATE);

I would like to know if my SQL insert code is OK.
Here is my table :
-- Create table
Create table FNS_CHAMP_DEV
(
IDAUTO Integer not null generated always as identity ( start with
0, increment by 1, no cache) primary key,
BB_COL BLOB,
CB_COL CLOB
);
Is my syntax SQL below correct to insert a PDF file in BLOB Column ?
-- SQL insert request :
SELECT IDAUTO AS Last_ID from final table (Insert into FNS_CHAMP_DEV (
BB_COL ) Values(blob('C:\DOC_TECHNIQUE_WD\TEC_VISUAL_STUDIO\WPF_VISUAL_STUDIO.pdf')));
Thanks
I have a table named masterregistry and it contains all the info and business logic in it and the data type of the colum is clob
desc master_registy:
id number not null,
name varchar2(100),
value clob
select value from master_registry where name='REG_DATE';
o/p
11-10-17
This date is common across all the business logic, I need to query my tables which has ,
desc get_employee
====================
id number not null,
first_name varchar2(100),
last_name varchar2(100),
last_mod_dt timestamp
Now I need to get all the values from the get_employee whose last_mod_dt should be greater than the value of master_registry where name='REG_DATE'.The value in the latter table is clob data, how to fetch and compare the date of a clob data against the timestamp from another table. Please help.
Maybe you need something like this.
SELECT *
FROM get_employee e
WHERE last_mod_dt > (SELECT TO_TIMESTAMP (TO_CHAR (VALUE), 'DD-MM-YY')
FROM master_registy m
WHERE m.id = e.id);
DEMO
Note that i have used the column value directly in TO_CHAR. You may have to use TRIM,SUBSTR or whatever required to get ONLY the date component.
I have a question. I have this control files that works fine when I run it from a windows client. However when I run it directly in Linux, it shows load complete but when I look at my oracle data, there is NO DATA and there are even bad records. Below is my control file that works well in windows but fails in Linux.
NOTE: The control file works if I remove the string or date converted fields
Control file
load data
infile 'HOME/INPUT/FILEA.dat'
badfile 'HOME/BAD/FILEA.bad'
discardfile 'HOME/DIS/FILEA.dsc'
truncate
into table TEST
fields terminated by '|'
trailing nullcols
( ABCcode CHAR(11),
ABCID CHAR(6),
ABC_SEQNO "to_number(:ABC_SEQNO,'999999')",
PSNO "to_number(:PSNO,'99999999999.999')",
ABDF CHAR(1),
ABCFI CHAR(1),
ABC_DATE NULLIF ABC_DATE="00000000" "to_date(:ABC_DATE, 'YYYYMMDD')",
XZY_date NULLIF XZY_date="00000000" "to_date(:XZY_date, 'YYYYMMDD')",
DESC CHAR(1))
Any help or ideas to get this code to run in Linux will be appreciated
Notes about the logfile: The logfile had the following
ORA-00604: error occurred at recursive SQL level 1
ORA-12899: value too large for column "ABCschema"."TEST"."ABC_DATE" (actual: 9, maximum: 8)
Also, the date conversion had the following
NULL if ABC_DATE = 0X3030303030303030(character '00000000')
SQL string for column : "to_date(:ABC_DATE, 'YYYYMMDD')"
Your TEST table has the ABC_DATE column defined as VARCHAR2(8), not as a DATE.
If I create a table as:
create table test (
ABCcode VARCHAR2(11),
ABCID VARCHAR2(6),
ABC_SEQNO NUMBER,
PSNO NUMBER,
ABDF VARCHAR2(1),
ABCFI VARCHAR2(1),
ABC_DATE DATE,
XZY_date DATE,
"DESC" VARCHAR2(1)
);
and have a data file with:
A|B|1|2.3|C|D|20140217|20140218|E
then it loads fine. If I recreate the table as:
create table test (
ABCcode VARCHAR2(11),
ABCID VARCHAR2(6),
ABC_SEQNO NUMBER,
PSNO NUMBER,
ABDF VARCHAR2(1),
ABCFI VARCHAR2(1),
ABC_DATE VARCHAR2(8),
XZY_date DATE,
"DESC" VARCHAR2(1)
);
... then the same control file and data file now give me:
Record 1: Rejected - Error on table TEST, column ABC_DATE.
ORA-12899: value too large for column "<schema>"."TEST"."ABC_DATE" (actual: 9, maximum: 8)
You are converting the string value to a date, but then you're doing an implicit conversion back to a string when it actually inserts the data into the VARCHAR2 column. When it does that it's using your NLS_DATE_FORMAT settings, and the error I got was from having that set to DD-MON-RR.
You have three options really. Either modify your table to have actual DATE columns; or change the control file so it just inserts the plain text value and doesn't do the date conversion at all; or massage your environment so the conversion back to a string gets the format you want the string to be.
Only the first one is really sensible - if it's a date value, always store it as a DATE, never as a string.
The 0X30... thing isn't a problem, that's just showing the internal representation it's using.
I am not sure if this is duplicated ,I havent find it in the search.
I have a table called mytable that has column STORY the type of this column is CLOB
mytable
The elder tree
Soldiers
Going for a hunt
The blue moon
If i write :
select story from mytable
I will have the result:
Mytable
1-clob
2-clob
3-clob
4-clob
What I want what inside CLOB , can I achieve that ?
dbms_lob.substr( clob, bytes, startbyte );
but in sql you can retrieve only 4000 bytes into varchar
<code>
sql>CREATE TABLE Employees
(
Id int,
Name varchar(50) not null,
Photo varbinary(max) not null
)
</code>
This code is showing error like this:
photo varbinary(max) not null
*
ERROR at line 5:
ORA-00907: missing right parenthesis
Please help
You should use BLOB (Binary Large Object) which is ideal for storing multimedia content like images.
Check this out for storing images using BLOB.
You can create the table like below and insert into the table, below are the sample scripts for that
create table graphics_table (
bfile_id number,
bfile_desc varchar2(30),
bfile_loc bfile,
bfile_type varchar2(4));
INSERT INTO graphics_table
VALUES(4,'April Book of Days Woodcut',bfilename('GIF_FILES','APRIL.JPG'),'JPEG');
INSERT INTO graphics_table
VALUES(30,'',bfilename('GIF_FILES','SHAPIROS.GIF'),'GIF');
If u need more Info on this please refer to

First the question that has been posted is for SQL
varbinary(max) is a new datatype in sql2012
Cast f(x) will be used in order to convert the image into Binary format.
The insert query for the insertion of image is
insert into Employees values(1, 'ABC', cast('path\abc.jpeg') as varbinary(max));
