问题 I have search this forum and via google for an answer for my question, but I can't find a specific answer for my challenge. That is why I am asking it here to hope to receive an answer from one of you guys.

问题 When I run a query like: SELECT * FROM CAR; the results appear but each row wraps to several lines. How can I stop this wrapping so that each row appears on a single line? 回答1: Had the same problem, even after changing set lines to a big number: select * from dba_directories; OWNER DIRECTORY_NAME ------------------------------ ------------------------------ DIRECTORY_PATH --------------------------------------------------------------------------------------------------------------------------

问题 I've been tinkering with sqlplus for awhile now, and I've managed to get sqlplus to read the contents of a file into a substitution variable as such: exit | sqlplus -s login/pass@db @script.sql "`cat file.txt`" This mostly works as my script requires... even newlines in the file are preserved. However, I was only using a sample file which was 50 or 60 bytes in size. The actual files I'll end up using will be at least a few kilobytes. So it was at this point I decided to check the max size of

问题 I'm doing the following spooling statement: SET VERIFY OFF SET FEEDBACK OFF SET HEADING OFF SET TRIMSPOOL ON SET TERM OFF SPOOL &pathRelations START scripts/relations.sql &parent SPOOL OFF SET TERM ON The scripts/relations.sql file contains a simple select statement. Unfortunately, the spooled file contains an empty line as the first one in the file. This line causes trouble in our framework. Of course I could get rid of these line through sed but ain't there a way to suppress its creation in

问题 I have a shell script that calls file.sql I am looking for a way to pass some parameters to my file.sql. If I don't pass a variable with some value to the sql script, I will have to create multiple .sql files with SELECT statement and all that would change is few words. My shell script calls file.sql: sqlplus -S user/pass@localhost echo " Processing triples" ./load_triples.sh BUILDING/Mapping_File BUILDING Y >> load_semantic.log @/opt/D2RQ/file.sql exit; EOF And this is how my file.sql looks

问题 I need to export a table in the database to a tab separated values file. I am using DBI on Perl and SQL Plus. Does it support (DBI or SQL Plus) exporting and importing to or from TSV files? I can write a code to do my need, But I would like to use a ready made solution if it is available. 回答1: It should be relatively simple to dump a table to a file with tab-separated values. For example: open(my $outputFile, '>', 'myTable.tsv'); my $sth = $dbh->prepare('SELECT * FROM myTable'); $sth->execute

问题 I have several scripts that I would like to start from a menu presented to the SQLPlus user. Something like: Please make a selection: 1: Do script a 2: Do script b 3: Do script c I just need a point in the right direction, not a quick answer. 回答1: Here is a SQL Plus script to do that: prompt Please make a selection: prompt 1: Do script a prompt 2: Do script b prompt 3: Do script c accept selection prompt "Enter option 1-3: " set term off column script new_value v_script select case '
