I have a requirement where I suppose to load the csv file using Oracle Loader. But this csv file have first two line as header and we want to exclude it in load.
How we can skip it?
The 11g SQL Loader documentation states that in your control file, you should just make sure you have an options clause. Here is an example of how you could implement this:
OPTIONS (SKIP=2)
LOAD DATA
INFILE 'my_new_records.csv'
BADFILE 'my_new_records.bad'
DISCARDFILE 'my_new_records.dsc'
APPEND
...

I'm working on a task to load Database table from a flat file. My database table has 60 columns.
Now, In SQL LOADER control file, Is it mandatory to mention all the 60 fields ?
Is there a way to tell SQL LOADER that all 60 columns should be treated as required without mentioning the fields in the Control File ?
Oracle 12c (and higher versions) offer express mode.
In a few words (quoting the document):
The SQLLoader TABLE parameter triggers express mode. The value of the TABLE parameter is the name of the table that SQLLoader will load. If TABLE is the only parameter specified, then SQL* loader will do the following:
Looks for a data file in the current directory with the same name as the table being loaded that has an extension of ".dat". The upper/lower case used in the name of the data file is the same as the case for the table name specified in the TABLE parameter
Assumes the order of the fields in the data file matches the order of the columns in the table
Assumes the fields are terminated by commas, but there is no enclosure character
(...) order of the fields in the data file matches the order of the columns in the table. The following SQL*Loader command will load the table from the data file.
sqlldr userid=scott table=emp
Notice that no control file is used. After executing the SQL*Loader command, a SELECT from the table will return (...)
I guess that's what you're after.
As I am inserting data from a CSV file to a oracle table using SQL Loader and it is working fine .
LOAD DATA
INFILE DataOut.txt
BADFILE dataFile.bad
APPEND INTO TABLE ASP_Net_C_SHARP_Articles
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
(ID,Name,Category)
above settings are being used to do that but I do not want to specify any of the column name ex. (ID,Name,Category) .
Is this possible or not if yes can anybody tell me how..
In SQL*Loader you need to specify the column names. If you still persist in ignoring the column names in the control file, then I would suggest you to use SQL to "discover" the name of the columns and dynamically generate the control file and wrap it via shell script to make it more automated.
Meanwhile, you can consider External Tables which uses the SQL*Loader engine, so you will still have to perform some dynamic creation here for your input file as suggested above. But you can create a script to scan the input file and dynamically generate the CREATE TABLE..ORGANIZATION EXTERNAL command for you. Then the data becomes available as if it were a table in your database.
You can also partially skip the columns if that would help you, by using FILLER. BOUNDFILLER (available with Oracle 9i and above) can be used if the skipped column's value will be required later again.
I trie to load a csv file into my oracle database. i use the script below for insert. But it dosen't work. The word 'DATA' in the first line is underlined and comment as "bad syntax" --- Why?
LOAD DATA INFILE 'c:\\SCHWEIZER_DATA_TABLE.csv'
INTO TABLE PEP
CHARACTER SET UTF8
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 ROWS;
You're trying to use SQL*Loader control file syntax. LOAD is not a SQL command, and you can't use that control file as a statement in SQL Developer.
You can use SQL*Loader if you have the full client or server installed on your PC - the instant client does not include it. If you can put the file on the server you could use an external table.
But SQL Developer has its own data import wizard which you can use to load the data from your file.
Use this wizard to import data into a table. For example, if you right-click the Tables node or a table name in the Connections navigator and select Import Data, you can specify the .source file (such as a spreadsheet or a delimited file) from which to import data. You create a table and import data into it, or import data into an existing table.
I have a CSV file, with first line as a header. Is there a HIVE SerDe that can create table using CSV header as well infers data type then it is the best.
Short answer - No.
What you're looking for is outside the scope of what SerDes are designed to do. There are, however, tools available that will create a table from a CSV with headers as an intermediate step. Check out hue.
I have never worked with Oracle. This is the first time and the job is quite tricky. I have a text file with records delimited with tab. These records are to be imported into a database using pl-sql. I have searched online but the solutions suggests using SQL Loader utility. But the requirement is to do that using sql statements. No command line utility. Preferable the SP or UDF will take file path and database name as input parameters and it will import the records when executed. Is this possible? Can someone provide me sample sql statements or any link that explain this process step by step? Also note that there can be blank records in file. Thanks in advance.
External Tables seems like the best approach.

UTL_FILE is possible but you would have to write the code to parse the tab delimited text etc.
