Connecting SQL*PLUS with a shell script | ||
Here's a piece that allows to execute select statements on an Oracle database from a shell script.
It consists of two parts: a shell function (read_sql_stmt) and the part that actually
uses the function.
#!/bin/bash read_sql_stmt() { typeset stmt=$1 typeset login=$2 echo " set feedback off verify off heading off pagesize 0 $stmt; exit " | sqlplus -s $login }
The second part: read_sql_stmt is executed with an SQL statement and a login, its output is piped into
an ordinary shell while loop:
read_sql_stmt "select username, user_id from dba_users" "system/system_pw" | while read u i do echo "user $u has userid $i" done |
