sqlplus

I'm watching a Script in Oracle and I see something I don't recognize REM INSERTING into database1."Users" SET DEFINE OFF; Insert into database1."Users" ("id","right") values ('1','R'); I'm looking for documentation about "set define off" and it's literally writing "disable the parsing of commands to replace substitution variable with their values" I don't really understand what they want to say. Can anyone help me? By default, SQL Plus treats '&' as a special character that begins a substitution string. This can cause problems when running scripts that happen to include '&' for other reasons:

How can I write an insert statement which includes the & character? For example, if I wanted to insert "J&J Construction" into a column in the database. I'm not sure if it makes a difference, but I'm using Oracle 9i. I keep on forgetting this and coming back to it again! I think the best answer is a combination of the responses provided so far. Firstly, & is the variable prefix in sqlplus/sqldeveloper, hence the problem - when it appears, it is expected to be part of a variable name. SET DEFINE OFF will stop sqlplus interpreting & this way. But what if you need to use sqlplus variables and

Is it possible to do something like this? $ sqlplus -s user/pass "select 1 from dual" or $ echo "select 1 from dual" | sqlplus -s user/pass I know I can put select 1 from dual in a file and do this: $ sqlplus -s user/pass @myFile.sql but I'm wondering if it's actually necessary to create a file just to satisfy sqlplus Just be aware that on Unix/Linux your username/password can be seen by anyone that can run "ps -ef" command if you place it directly on the command line . Could be a big security issue (or turn into a big security issue). I usually recommend creating a file or using here document

I have a .sql file, which is a bunch of oracle pl/sql commands and I want to create a shell script to run these commands. Suppose that user/pass@server is my credentials. What will be the shell script to do such a task? For example: sqlplus -s admin/password << EOF whenever sqlerror exit sql.sqlcode; set echo off set heading off @pl_script_1.sql @pl_script_2.sql exit; EOF Wouldn't something akin to this be better, security-wise?: sqlplus -s /nolog << EOF CONNECT admin/password; whenever sqlerror exit sql.sqlcode; set echo off set heading off @pl_script_1.sql @pl_script_2.sql exit; EOF If you

Using SQL Plus, you can run a script with the "@" operator from the command line, as in: c:\>sqlplus username/password@databasename @"c:\my_script.sql" But is it possible to just run a single command with a similar syntax, without a whole separate script file? As in: c:\>sqlplus username/password@databasename @execute some_procedure I am interested in this because I want to write a batch file that simply executes a command, without generating a bunch of two-line ".sql" files. I'm able to run an SQL query by piping it to SQL*Plus: @echo select count(*) from table; | sqlplus username/password
