Summary
-------

SimpleSQLite is a Python library to simplify the table creation and data insertion into SQLite database.

Features
--------

- Automated SQLite table creation from data
- Support various data types of record(s) insertion into a table:
- ``dict``
- ``namedtuple``
- ``list``
- ``tuple``
- Create table(s) from:
- CSV file/text
- JSON file/text
- `TableData` instance loaded by `pytablereader <https://github.com/thombashi/pytablereader>`__

Examples
========

Create a table
--------------

Create a table from data matrix
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. code:: python

import json
from simplesqlite import SimpleSQLite

table_name = "sample_table"
con = SimpleSQLite("sample.sqlite", "w")

# create table -----
data_matrix = [
[1, 1.1, "aaa", 1, 1],
[2, 2.2, "bbb", 2.2, 2.2],
[3, 3.3, "ccc", 3, "ccc"],
]
con.create_table_from_data_matrix(
table_name,
attr_name_list=["attr_a", "attr_b", "attr_c", "attr_d", "attr_e"],
data_matrix=data_matrix)

# display values in the table -----
print(con.get_attr_name_list(table_name))
result = con.select(select="*", table_name=table_name)
for record in result.fetchall():
print(record)

# display data type for each column in the table -----
print(json.dumps(con.get_attr_type(table_name), indent=4))


.. code::

['attr_a', 'attr_b', 'attr_c', 'attr_d', 'attr_e']
(1, 1.1, u'aaa', 1.0, u'1')
(2, 2.2, u'bbb', 2.2, u'2.2')
(3, 3.3, u'ccc', 3.0, u'ccc')
{
"attr_b": " REAL",
"attr_c": " TEXT",
"attr_a": " INTEGER",
"attr_d": " REAL",
"attr_e": " TEXT"
}

Create a table from CSV
~~~~~~~~~~~~~~~~~~~~~~~

.. code:: python

from simplesqlite import SimpleSQLite

with open("sample_data.csv", "w") as f:
f.write("\n".join([
'"attr_a","attr_b","attr_c"',
'1,4,"a"',
'2,2.1,"bb"',
'3,120.9,"ccc"',
]))

# create table ---
con = SimpleSQLite("sample.sqlite", "w")
con.create_table_from_csv("sample_data.csv")

# output ---
table_name = "sample_data"
print(con.get_attr_name_list(table_name))
result = con.select(select="*", table_name=table_name)
for record in result.fetchall():
print(record)


.. code::

['attr_a', 'attr_b', 'attr_c']
(1, 4.0, u'a')
(2, 2.1, u'bb')
(3, 120.9, u'ccc')

Insert records into a table
---------------------------

Insert dictionary
~~~~~~~~~~~~~~~~~

.. code:: python

from simplesqlite import SimpleSQLite


table_name = "sample_table"
con = SimpleSQLite("sample.sqlite", "w")
con.create_table_from_data_matrix(
table_name,
attr_name_list=["attr_a", "attr_b", "attr_c", "attr_d", "attr_e"],
data_matrix=[[1, 1.1, "aaa", 1, 1]])

con.insert(
table_name,
insert_record={
"attr_a": 4,
"attr_b": 4.4,
"attr_c": "ddd",
"attr_d": 4.44,
"attr_e": "hoge",
}
)
con.insert_many(
table_name,
insert_record_list=[
{
"attr_a": 5,
"attr_b": 5.5,
"attr_c": "eee",
"attr_d": 5.55,
"attr_e": "foo",
},
{
"attr_a": 6,
"attr_c": "fff",
},
]
)

result = con.select(select="*", table_name=table_name)
for record in result.fetchall():
print(record)


Insert list/tuple/namedtuple
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. code:: python

from collections import namedtuple
from simplesqlite import SimpleSQLite


table_name = "sample_table"
con = SimpleSQLite("sample.sqlite", "w")
con.create_table_from_data_matrix(
table_name,
attr_name_list=["attr_a", "attr_b", "attr_c", "attr_d", "attr_e"],
data_matrix=[[1, 1.1, "aaa", 1, 1]])

SampleTuple = namedtuple(
"SampleTuple", "attr_a attr_b attr_c attr_d attr_e")

con.insert(table_name, insert_record=[7, 7.7, "fff", 7.77, "bar"])
con.insert_many(
table_name,
insert_record_list=[
(8, 8.8, "ggg", 8.88, "foobar"),
SampleTuple(9, 9.9, "ggg", 9.99, "hogehoge"),
]
)

result = con.select(select="*", table_name=table_name)
for record in result.fetchall():
print(record)


.. code::

(1, 1.1, u'aaa', 1, 1)
(7, 7.7, u'fff', 7.77, u'bar')
(8, 8.8, u'ggg', 8.88, u'foobar')
(9, 9.9, u'ggg', 9.99, u'hogehoge')
