Sailfish os + SQL

i can't use any programming language for app developing.

You can use sqlite3 on the command line. Make sure, sqlite is installed:

$ rpm -qf /usr/bin/sqlite3
sqlite-3.13.0+git3-1.3.12.jolla.armv7hl

Now you can use SQL:

$ sqlite3 /tmp/test.db
SQLite version 3.13.0 2016-05-18 10:57:30
Enter ".help" for usage hints.
sqlite> create table test (name varchar primary key, age int);
sqlite> insert into test values ('eierkopp', 99);
sqlite> select * from test;
eierkopp|99
