I have 15 million of records as csv, want to load through sqlloader Is sqlloader is the right option to load high volume of data? I have loaded with 2.5 lac records which has taken 4 mins to load.
View 9 RepliesI am in the very early planning stages of a project the goal of which is to identify separate organizations which may in fact be the same organization.
Our first implementation of this task was a process designed to look for a few thousand organizations in a pool of a few hundred thousand organizations. To accomplish this we made heavy use of Oracle's Text index as well as a custom index type we created which utilized n-grams. This approach worked quite well for on-demand editing of the organizations, in which a user might log in and say in addition to what we already know about organization A we also know x, y and z does that change anything and worked acceptably well for the bulk processing we did on our "known" information once a week running for a couple of hours on the weekend.
We have now been tasked with reworking this initial implementation only now we want to look at a set consisting of several million organizations for potential matches which exist within the set. As in our initial implementation we will be breaking what we know about organizations into groupings so we aren't comparing a phone number to an email address and normalizing the data as much as we can so we ignore things like case and punctuation. Even after all this we are still talking about looking for similar values in a group which might be in the tens of millions (some types of data will have more than one value per organization).
My initial thought on the problem is to use n-grams though not in the way we did in the past. The basic idea here is that we break the search values up into all the substrings it is made of and look for other values which have a high number of those substrings in common.
SQL & PL/SQL was the best place for the question, but I could not think of a better one.
I am attempting to insert date data into a column using sqlldr...Here's the current format:
2010-03-01 00:20:19.277
So far, I haven't gotten anything to work. I would like to trim the .277 from the existing date. Here's my latest attempt:
birthdate DATE "to_date(substr(birthdate,1,19),'YYYY-MM-DD HH24:MI:SS')"
I am trying to load my data from a CSV file to an oracle table using SQL LOADER. What should be the syntax of DATE MASK for the below kind of data.
02MAR1948:00:00:00.000
24SEP1950:00:00:00.000
I am using the following control file
LOAD DATA

[code]...
I want to load a delimited file that contains many records which contained within the table where I'm going to load a date type field and I need to do this by concatenating three fields
field1 = 1 - this is the day
field2 = 11 - this corresponds to the month
field3 = 5 - this corresponds to the year
I need is in the field Save as type date 01/11/2005 i don´t know how to do it but I tried as follows but I get error loading.
"TO_DATE (TO_CHAR (: field1 ||'/'|| DECODE (: field2, 1, 'JAN', 2, 'FEB', 3, 'MAR', 4, 'APR', 5, 'MAY', 6 , 'JUN', 7, 'JUL', 8, 'AUG', 9, 'SEP', 10, 'OCT', 11, 'NOV', 12, 'DEC': field2 )||'/'|| : field3)) "
I have another interesting SQL Loader issue. I have created 2 prior topics RE: "Trapping SQL Loader summary counts" and "Using Sql Loader issue". This new issue is along the same lines, but unfortunately the same input csv file has a date field that is has a different input format..
The 10G Oracle Table looks like...
---------------------------
CREATE TABLE PTLIVE.MODULE_CSV_LOADS
( MODULE_ID NUMBER (20),
MODULE_TAGNUMBER VARCHAR2(100),
MODULE_SERIAL_NUMBER NUMBER (20,0),
[code]...
My initial control file looks like...
-----------------
OPTIONS (SKIP=1)
load data
infile 'J:GrowerRound_ModulesCrop2011ProcessedBatch_2011Jul12_081326_746563.csv'
BADFILE 'J:GrowerRound_ModulesCrop2011LogsBatch_2011Jul12_081326_746563.bad'
[code]...
The input csv data file (for this example) contains 3 records. The first is a heading record that is skipped. The 2nd record
is correct and the field entitled "GMT Date" contains a value of
"16/05/2011". The 3rd record, however, has a date of "2011/5/18", which get rejected by the above control file, as the output SQL Loader log indicates...
Record 2: Rejected - Error on table PTLIVE.MODULE_CSV_LOADS, column DATEPICKED.
ORA-01861: literal does not match format string
Now we will be receiving literally hundreds of these csv files and in testing I have found that when I open the csv file (the default is Excel), and Excel must alter its display, as all date appear 100% okay. However, upon opening the csv file with Wordpad, I discovered the dates in the same file had these 2 different formats. So the control file was attempting to concat the input csv file "GMT Date" in one format with the input "GMT_TIME" to load the output value into the Oracle table column
"DATEPICKED" ... but different date formats cause some records to be rejected.
It would be super if SQl Loader could use a IF clause or an OR clause to execute loading the date in one or more input formats. We only expect the 2 foramts DD/MM/YYYY or YYYY/MM/DD....however, there could be 6 different combinations in theory.
I thought about writing a Function or Procedure to analyst the input date and output a standard one to load into the Oracle column
The prod stats has been implemented in development. The stats has been gathered 2 months back on dev while in production the stats has been gathered 2 weeks back.
My question shouldn't the high volume of data causes changes in plan in both the environment? My thinking is that plan can be different as the high volume of data are changing in prod it may lead to a different plan.

I installed oracle 10G complete so I can have everything. But now I cannot run sql loader. I check my oracle devsuitehome directory and I cannot find sqlldr.exe
I need to install sql loader separately? I can't find sql loader installer on web.
SQL Loader - How to implement/Best solution.
I have 3 tables with their columns:
- MASTER_TABLE - MASTER_ID, DATA;
- PARENT_TABLE_A - MASTER_ID, DATA;
- PARENT_TABLE_B - MASTER_ID, DATA.
And the file I need to import has lines like the ones below:
MMMASTER_TABLE1
PAPARENT_TABLE_A1
PBPARENT_TABLE_B1
MMMASTER_TABLE2
PAPARENT_TABLE_A2
PBPARENT_TABLE_B2
MMMASTER_TABLE3
PAPARENT_TABLE_A3
PBPARENT_TABLE_B3
The line means:
- 1 - M or P: indicates which table to insert: MASTER or PARENT;
- 2 - M or A or B: indicates MASTER, PARENT_A, PARENT_B;
- 3:18 - DATA.
Based on the values above, what I need to do is:
1. Load a line to MASTER_TABLE;
2. Load a line to PARENT_TABLE_A pointing to its relative line in MASTER_TABLE;
3. Load a line to PARENT_TABLE_B pointing to its relative line in MASTER_TABLE;
4. In the original file line, there is nothing I can use to join a MASTER line with a PARENT line.
The result would be:
MASTER_ID PARENT_DATA
1 PARENT_TABLE_A1
1 PARENT_TABLE_B1
2 PARENT_TABLE_A2
2 PARENT_TABLE_B2
I tried to use both: SEQUENCE and Sequence.NextVall (CurrVal) but they only work when using ROWS=1 and the file I need to load has millions of rows, so I need direct path loading.Also, I read about External Table, but it does not suit my needs because the Application server is not the same as Database server, which is needed by external tables.
in this case is better load the data to a temporary table and then insert to the other tables, I found almost the same question in the topic pointed by the link below: URL....
I want to load geometry into a table using sql*loader. My datafile contains geometry defined as WKT URL...., a standard for geometry and also Oracle has a function called sdo_util.from_wktgeometry.If I'm using a separate 'insert into' statement using this function in sql*plus, there's no problem. But if I'm using the same function in my control-file for sql*loader import, I get a sql*loader-418 error: "bad datafile for column geometrie".
Why and how I can import WKT using sql*loader?

I want to use SQL loader in a procedure..will it be possible to use it in procedure and if yes then how..?
View 4 Replies View RelatedMy data file contains records with RECORD_TYPE '01', '02', '03' and '04' in position (30:31) I use sql loader to load this data into a table. I need to load ONLY rows with RECORD_TYPE ='04'. I have to output all the other rows into a file, so I decided to use DISCARD file. Now, those with RECORD_TYPE ='4' have to be loaded into different columns depending on the value in position (267:268).
So, my ctl file should look something like:
WHEN (30:31) = '04'
into table MYDATA
WHEN (267:268) != 'O '
into table MYDATA
WHEN (267:268) = 'O '
and whatever is not '04' goes to discard file.
I tried to use
into table MYDATA
WHEN (30:31) = '04' and (267:268) != 'O '
into table MYDATA
WHEN (30:31) = '04' and (267:268) = 'O '
but I don't get the right result in terms of the discard file.
Is there any way to put together all these conditions?
The SQL loader somehow is loading only first record. The data file is a csv and the end of line character is a new line. Some text fields have multiple new lines.

dfsdfd,
i want to move this column data into a single table column.But due to because of delimited "," it is splitting into number of columns
I had a requirement of loading flatfile into staging table using SQL Loader, One of the columns in the the Flat file is having values FALSE or TRUE and my requirement is that I load 0 for FALSE and 1 for TRUE which can be achieved by simple DECODE function...I did use decode and tried to load several times but did not work.

I did try putting a trim as well as SUBSTR but did not work....the cloumn just doent get any values in the output (just null or say free space)
1) can we use a CSV file as a Data file in any format (fixed, delimited...) of Sql loader. I tried, but not succeeded.
2) if not then tell me the reason for it....
3) Also tell me is there any restriction on using the file format for a datafile?
I have a small problem when I am trying to load data into a table using SQL Loader. The data I am trying to load should be a number, but it is in the format '999,999,999 USD'. When I try to load the data, I am getting an invalid number error, due to the USD (I have already accounted for the thousands seperators). My question is, how can I load the data as a number with USD in the format?
