I'm trying to parse line into columns in control file.
I get "Field in data file exceeds maximum length"
My control file:
OPTIONS (
ERRORS = 1,
DIRECT=TRUE,
LOAD=10
)
load data
APPEND
into table table_1
fields terminated by "#x000A"
(
Column0 BOUNDFILLER,
Column1 "SUBSTR(:Column0, 1, 10)"
)
Table:
create table table_1 (
Column0 VARCHAR2(2000)
Column1 VARCHAR2(124)
);
It looks like it happens because length of each row is more that 2000 but I checked the file and it's less that 1000.
So why I get this error?
The error is here. Column0 BOUNDFILLER, this line is equal Column0 BOUNDFILLER char(255),.
char(255) is default value.
You are trying to put 1000 into variable with space only for 255.
Solution is Column0 BOUNDFILLER char(2000) ,

I am trying to put pandas table like this into my Oracle Database.
My pandas table looks like this
this is my script to insert the data
INSERT INTO DATA
(NO_TRANSMITTER,ZONA,STATUS_PELABUHAN,TO_DATE(REPORTDATE,'YYYY-MM-DD HH24:MI:SS'),STATUS)
VALUES(:1,:2,:3,:4,:5)
It gets result like this
There is a problem with Oracle ORA-00917: missing comma
I don't know where comma needed to. Thanks for the help.
Put TO_DATE into the VALUES clause and not into the column identifier list:
INSERT INTO DATA (
NO_TRANSMITTER,
ZONA,
STATUS_PELABUHAN,
REPORTDATE,
STATUS
) VALUES (
:1,
:2,
TO_DATE(:3,'YYYY-MM-DD HH24:MI:SS'),
:4,
:5
)
Or, if the value in Pandas, is already stored as a datetime (and not a string) then simplify it to:
INSERT INTO DATA (
NO_TRANSMITTER,
ZONA,
STATUS_PELABUHAN,
REPORTDATE,
STATUS
) VALUES (
:1,
:2,
:3,
:4,
:5
)
At a given time I stored the result of the following ORACLE SQL Query :
SELET col , TO_CHAR( LOWER( STANDARD_HASH( col , 'MD5' ) ) AS hash_col FROM MyTable ;
A week later, I executed the same query on the same data ( same values for column col ).
I thought the resulting hash_col column would have the same values as the values from the former execution but it was not the case.
Is it possible for ORACLE STANDARD_HASH function to deliver over time the same result for identical input data ?
It does if the function is called twice the same day.
All we have about the data changing (or not) and the hash changing (or not) is your assertion.
You could create and populate a log table:
create table hash_log (
sample_time timestamp,
hashed_string varchar2(200),
hashed_string_dump varchar2(200),
hash_value varchar2(200)
);
Then on a daily basis:
insert into hash_log values
(select systimestamp,
source_column,
dump(source_column),
STANDARD_HASH(source_column , 'MD5' )
from source_table
);
Then, to spot changes:
select distinct hashed_string ||
hashed_string_dump ||
hash_value
from hash_log;
I have a huge table with 20 million records and I want to split the table into 10 equal chunks.
The problem is the table only has varchar columns. I am able to use ROWNUM column and split the table into equal chunks but I couldn't seem to get the Start and End value of the varchar column into the query result set. Below is the query.
with bkt as (
select ROWNUM, width_bucket(ROWNUM, 1, 100100, 10) as id_bucket from "BOOKER"."test"
)
select id_bucket
, min(ROWNUM) as bkt_start
, max(ROWNUM) as bkt_end
, count(*)
from bkt
group by id_bucket
order by 1;
Please advise how can I add the varchar column with this query to give me the start and end varchar values of the column.
I'm trying to load the data from an xml file to a table. I get the below errors, please help me out.
Table:
CREATE TABLE TEST_XML
(FILL CHAR(30)
XMLDATA CLOB);
Here is my control file
LOAD DATA
INFILE *
TRUNCATE INTO TABLE TEST_XML XMLType(XMLDATA)
FIELDS ( FILL FILLER CHAR(100), XMLDATA LOBFILE(CONSTANT test_file.xml) TERMINATED BY EOF )
BEGINDATA 0
I get the below error:
Table TEST_XML, loaded from every logical record. Insert option in
effect for this table: TRUNCATE
Column Name Position Len Term Encl Datatype
------------------------------ ---------- ----- ---- ---- --------------------- FILL FIRST 100 CHARACTER (FILLER FIELD) XMLDATA
DERIVED * EOF CHARACTER
Static LOBFILE. Filename is test_file.xml
Record 1: Rejected - Error on table TEST_XML. ORA-01008: not all

For me it is invalid syntax in control file. Oder of key word is relevant. Also like after begindata
LOAD DATA
INFILE *
INTO TABLE TEST_XML
truncate
FIELDS
( FILL FILLER CHAR(100)
,XMLDATA LOBFILE(CONSTANT test_file.xml) TERMINATED BY EOF )

In order to load data (from a CSV file) into an Oracle database, I use SQL*Loader.
In the table that receives these data, there is a varchar2(500) column, called COMMENTS.
For some reasons, I want to ignore this information from the CSV file.
Thus, I wrote this control file:
Options (BindSize=10000000,Readsize=10000000,Rows=5000,Errors=100)
Load Data
Infile 'XXX.txt'
Append into table T_XXX
Fields Terminated By ';'
TRAILING NULLCOLS
(
...
COMMENTS FILLER,
...
)
This code seems to work correctly, as the COMMENTS field in database is always set to null.
However, if in my CSV file I have a record where the corresponding COMMENTS field exceeds the 500 characters limit, I get an error from SQL*Loader:
Record 2: Rejected - Error on table T_XXX, column COMMENTS.
Field in data file exceeds maximum length
Is there a way to really exclude the processing of my COMMENTS fields?
I can't reproduce your problem. I'm using Oracle 10.2.0.3.0 with SQL*Loader 10.2.0.1.
Here is my test case:
SQL> CREATE TABLE test_sqlldr (
2 ID NUMBER,
3 comments VARCHAR2(20),
4 id2 NUMBER
5 );
Table created
Control file:
LOAD DATA
INFILE test.data
INTO TABLE test_sqlldr
APPEND
FIELDS TERMINATED BY ';'
TRAILING NULLCOLS
( id,
comments filler,
id2
)
data file:
1;aaa;2
3;abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz;4
5;bbb;6
I'm using the command sqlldr userid=xxx/yyy#zzz control=test.ctl and I'm getting all the rows without errors:
SQL> select * from test_sqlldr;
ID COMMENTS ID2
---------- -------------------- ----------
1 2
3 4
5 6
You may try another approach, I'm getting the same desired result with the following control file:
LOAD DATA
INFILE test.data
INTO TABLE test_sqlldr
APPEND
FIELDS TERMINATED BY ';'
TRAILING NULLCOLS
( id,
comments "substr(:comments,1,0)",
id2
)
Update following Romaintaz's comment: I looked into it again and managed to get the same error as you when the size of the column exceeded 255 characters. This is because the default datatype of SQL*Loader is char(255). If you have a column with more data you will have to specify the length. The following control file solved the problem for a column with 300 characters:
LOAD DATA
INFILE test.data
INTO TABLE test_sqlldr
APPEND
FIELDS TERMINATED BY ';'
TRAILING NULLCOLS
( id,
comments filler char(4000),
id2
)
Hope this Helps,

Just to suggest a tiny improvement, you might try something like:
LOAD DATA
IN FILE test.data INTO TABLE test_sqlldr
APPEND
FIELDS TERMINATED BY ';'TRAILING NULLCOLS
(
id,
comments char(4000) "substr(:comments, 1, 200)",
id2)
Now you'll grab the first 200 characters (or any number you specify in it's place) of all comments - unless some of your input records have values for the comments field that exceed 4000 characters, in which they'll be rejected by loader with the 'exceeds max length' error noted earlier. But assuming that's rare or not the case, all the records will load with some of the comments truncated to 200 chars.
If you go over char(4000) you'll get a SQL Loader error - there's a limit to how far you can push the beast.
