Open-source Languages & Tools for z/OS

SQLite would be a great addition to your Open Source Tools. The current version (3.25.2) should compile without any changes and it would be a great back-end DB when a full blown Database is overkill.

SQLite is included in Python.

It works like this:
(131) python
Python 3.6.1 (default, Apr 7 2017, 13:59:34) [C] on zos
>>> import sqlite3
>>> conn=sqlite3.connect(‘my.db’)
>>> c = conn.cursor()
>>> c.execute(’’‘CREATE TABLE stocks (date text, trans text, symbol text, qty real, price real)’’’)
<sqlite3.Cursor object at 0x5008C78F10>
>>> c.execute(“INSERT INTO stocks VALUES (‘2006-01-05’,‘BUY’,‘RHAT’,100,35.14)”)
<sqlite3.Cursor object at 0x5008C78F10>
>>> conn.commit()
>>> c.execute(“SELECT * FROM stocks WHERE symbol = ‘RHAT’”)
<sqlite3.Cursor object at 0x5008C78F10>
>>> print(c.fetchone())
(‘2006-01-05’, ‘BUY’, ‘RHAT’, 100.0, 35.14)
>>> conn.close()
>>> exit()

As a stand alone product I could us in REXX Programs (or COBOL, or PL/I).
