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 sqlite3 mydatabase <<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.
