sql-loader

问题 When loading an external csv with Oracle SQL Loader is there a way to map the fields directly to each other in the control file? At the moment I'm doing a simple loading, so the position of the source fields is important. Is there a way to do it otherwise? So instead of: load data into table1 fields terminated by "," optionally enclosed by '"' (destination_field1, destination_field2, destination_field3) do something like: load data into table1 fields terminated by "," optionally enclosed by '

问题 I'm using SQL loader to load my data into database. Before I insert the data I need to remove existing data in the table: options(skip=1,load=250000,errors=0,ROWS=30000,BINDSIZE=10485760) load data infile 'G:1.csv' "str '^_^'" replace into table IMPORT_ABC fields terminated by "," OPTIONALLY ENCLOSED BY '"' trailing nullcols( . . . .) But I got error like: SQL*LOADER-926: OCI error while executing delete/truncate for table IMPORT_ABC ORA-30036: unable to extend segment by 8 in undo tablespace

问题 I have a excel sheet which has a format like: Name Address Phone# Age ----- ------- ------ ---- aaa xxx 123... 11 bbb yyy 345... 21 when i import this excel i have got headers(Name,Address,phone#,Age) as first row of the table. i want only data without headers. Can anyone please help. TA, Nishant 回答1: I've never used it, but the skip option should do what you need. You can define the number of rows to skip in your control file like this: OPTIONS (SKIP=1) LOAD DATA INFILE ... Or you can do it

问题 I have a Java utility for database imports. I'd like to be able to use sqlldr for performance on oracle. I could create the control and data files, but that doesn't seem like The Right Thing™ to do. I should be able to stream the data by providing INFILE "-" in the control file ( q1 - how? from command line, I can pipe " echo <data...> " to the sqlldr, but there must be a way to just stream the string into the input stream for the process? never used Java for this before). I can't see how to

问题 using sql loader, I know I can reference a ksh variable in my ctl file. For example I can write LOAD DATA INFILE '$PATH_IN_KSH/my_file.dat' ... I would like to add a WHEN clause like this WHEN (125:125) = '$P_NUMBER' P_NUMBER would have the value of a column in a table that I would retrieve with a select query. Is it possible to do that ? retrieve a value from a column with a select and somehow put it in the ksh variable so the ctl file can see it. (something with sql plus?) Thank you 回答1: As

问题 Case : My case is pretty straight forward. I have a Linux server machine. On that server, there are 2 users. One is root and the other is oracle . Now here is the thing, the root user does not know the sqlldr command, this command is recognized by oracle user only. I have a batch.sh file and in that file i have an sqlldr command that will insert record in the database. When i open terminal using oracle user, that batch.sh file runs according to the expectations. But when I run that batch file
