Update a column in table using SQL*Loader?

由 二次信任 提交于 2019-12-10 14:45:06
问题 I have written a SQL Script having below query. Query works fine. update partner set is_seller_buyer=1 where id in (select id from partner where names in ( 'A','B','C','D','E',... // around 100 names. )); But now instead of writing around 100 names in a query itself , I want to fetch all the names from the CSV file. I read about SQL*Loader on internet but i did not get much on update query. My csv file contain only names. I have tried load data infile 'c:\data\mydata.csv' into table partner

Oracle sqlldr timestamp format headache

由 独自空忆成欢 提交于 2019-12-10 02:43:48
问题 I'm struggling to get sqlldr to import a csv data file into my table, specifically with the field that is a timestamp. The data in my csv file is in this format: 16-NOV-09 01.57.48.001000 PM I've tried all manner of combinations in my control file and am going around in circles. I can't find anything online - not even the Oracle reference page that details what all the date/timestamp format strings are. Does anyone know where this reference page is, or what format string I should be using in

How to populate a timestamp field with current timestamp using Oracle Sql Loader

由 只愿长相守 提交于 2019-12-08 15:58:42
问题 I'm reading a pipe delimited file with SQL Loader and want to populate a LAST_UPDATED field in the table I am populating. My Control File looks like this: LOAD DATA INFILE SampleFile.dat REPLACE INTO TABLE contact FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"' ( ID, FIRST_NAME, LAST_NAME, EMAIL, DEPARTMENT_ID, LAST_UPDATED SYSTIMESTAMP ) For the LAST_UPDATED field I've tried SYSTIMESTAMP and CURRENT_TIMESTAMP and neither work. SYSDATE however works fine but doesn't give me the time of

Insert rows with batch id using sqlldr

由 别说谁变了你拦得住时间么 提交于 2019-12-08 05:55:38
问题 I am able to insert rows into a table using sqlldr with no worries. I would like to tag all rows of a file to a unique number so that I can treat them as one batch. I tried "my_db_seq.nextval" as batch id. But its not serving my purpose. So please advise on how to create a unique batch id for entire set of rows of a file while loading using sqlldr. 回答1: Wrap your call to the sequence in a function like this: create or replace function get_batch_id return integer is x exception; -- ORA-08002:

Can Oracle SQL*Loader process XML?

由 妖精的绣舞 提交于 2019-12-08 04:39:25
Does Oracle offer a standardized upload of XML formatted files? I thought that the canonical format that is used for XML output, structure = ROWSET/ROW/columname , could be uploaded back into the table again, by just running sqlldr with appropriate control file contents. But I cannot find anything about this anywhere on the web, and error messages after trials seem to indicate that it is only possible to upload XML into XML-type formatted tables, where I just want to upload data in a plain table but supply the data in XML format. No, SQL*Loader can only process "flat" files. One option is to

Oracle External Tables: Advanced Flat File Layout

由 旧巷老猫 提交于 2019-12-07 12:16:25
问题 I wish to create an external table in an Oracle database, retrieving its data from a flat file on the server. The format of this file is non-trivial. Each line in this file can be one of several different layouts, depending on the line's prefix (the prefix itself is always a fixed length). For example, a line beginning with 'TYPE1' would have a different layout than a line beginning with 'TYPE2' . I have read that external tables can take advantage of all the constructs made available to SQL

SQL*Loader stuck after loading 4.2 billion records

由 岁酱吖の 提交于 2019-12-07 02:34:00
问题 We are stuck with a problem in sql loader. We are trying to load a data file with around 4.6 billion rows (nearly 340 GB) into 2 oracle tables on the basis of some when condition using Sql Loader. But after loading 4.2 billion records the SQL loader process is getting completed without throwing any errors even when rest of the records are still to be loaded. There are no dicarded or bad records as well. Is there any limit for the number of records SQL Loader can load? Could not find any such

Oracle Sql Loader “ORA-01722: invalid number” when loading CSV file with Windows line endings

由 你离开我真会死。 提交于 2019-12-07 00:02:35
问题 I am using Oracle Sql Loader Utility from Linux shell to load csv data into Oracle DB. But I have noticed that if source csv files lines endings are '\r\n' (Windows format), sqlldr fails to load data for last column. For example, if last column is of FLOAT type (defined in ctl file as 'FLOAT EXTERNAL'), sqlldr fails with 'ORA-01722: invalid number': Sqlldr ctl file: OPTIONS(silent=(HEADER)) load data replace into table fp_basic_bd fields terminated by "|" optionally enclosed by '"' TRAILING

Oracle sqlldr TRAILING NULLCOLS required, but why?

问题 I have an abstruse sqlldr problem that's bothering me. My control file looks something like this: load data infile 'txgen.dat' into table TRANSACTION_NEW fields terminated by "," optionally enclosed by '"' TRAILING NULLCOLS ( A, B, C, D, ID "ID_SEQ.NEXTVAL" ) Data is something like this: a,b,c, a,b,,d a,b,, a,b,c,d If I don't put the TRAILING NULLCOLS in, I get the "column not found before end of logical record" error. But although some of the columns are null, the commas are all there, so I
