Making SQLITE/SQLITE3 executable scripts

Use "here document" statements to build complex script files with embedded SQL statements via the sqlite/sqlite3 utility.

#! /usr/bin/env bash

# execute some bash scripting commands here

sqlite3 mydatabase <<SQL_ENTRY_TAG_1
SELECT * 
  FROM mytable 
  WHERE somecondition='somevalue';
SQL_ENTRY_TAG_1

# execute other bash scripting commands here

SQL_ENTRY_TAG_2
SELECT *
  FROM myothertable
  WHERE someothercondition='someothervalue';
SQL_ENTRY_TAG_2

Note that being in a bash script means that you can expand $-variables inside the SQL code directly. This is,however,not advised unless you can be sure that only trusted,competent people will run your code. Otherwise you'll be facing SQL injection attacks.
