json-to-mysql's Issues

DIRECTORY_SEPARATOR

Hi there,

I just wanted to do a quick test under windows, and your path separators won't work here. You might want to use DIRECTORY_SEPARATOR instead of "/" in the future, to build your strings.

Goal 2: validate table structure

Given a JSON object, validate the construction of a mysql table, including sub-tables, foreign keys, and data types. Return a JSON object describing what edits should be made (new columns, change types, add NULLABLE, etc) to the existing table if any

Composer package

Please add composer installation instructions to Readme.md

need to handle array (object) subdata

How to receive subdata Events?

{ "CommandStatus": "0", "Events": [ { "ActivityId": "1" },{ "ActivityId": "2" },...,{ "ActivityId": "867" } ], "EventsCount": "867" }

Dont use PHP short tags (use <?php instead)

Many PHP environments come such as XAMPP are pre-configured to ignore PHP short tags (<?), better use the ones that work everywhere (<?php)

DatabaseException class not found; also mysql_connect (and similar are dropped from PHP)

Greetings:
I'd really like the approach of this project, but I am unable to utilize it, at its present form.
It does have potentials, however, to make a GREAT Project!
I was looking for a way to import any JSON into an SQLite3, but this should work, just as well.

JSON that I am trying to import is like this:
{
"stations":[
{
"id":"WYNI1",
"name":"DALE BITNER",
"elev":"6391",
"latitude":"43.049722",
"longitude":"-111.379444",
"state":"ID",
"distance":"",
"provider":"RAWS",
"link":"http://www.wrh.noaa.gov/mesowest/getobext.php?sid=WYNI1",

handle sub object and subsubobject data

when inserting data into a table, allow it to have data in sub objects, and create normal keys in the original object for that data. so:

{ "properties" : { "one" : true, "two" : false} }

becomes:

{ "properties_one" : true, "properties_two" : false}

Example typo and bug in line 208

bug in code
Line 208 in ExistingMYSQLTable.php should use variable $val instead of $value. You do not iterate with the correct element used.
Your example in README.md has a typo
$obj = $db->table("brandnewtable")->find(["id" => [4, 5, 6 7]]); should be
$obj = $db->table("brandnewtable")->find(["id" => [4, 5, 6, 7]]); note the missing comma.

Import nested JSON sub-arrays

Importing JSON with multiple sub-arrays nested to different depths fails with 'need to handle sub-array's' message.

example.php does not work

when I run:
$ php example.php

I get:

PHP Notice: Undefined variable: classLoader in /home/sbash/json-to-mysql/example.php on line 10
PHP Fatal error: Call to a member function addToClasspath() on null in /home/sbash/json-to-mysql/example.php on line 10

I only edited the file to add <?php as short tags do not work in my environment. I get this on php 7.x and 5.6...

I have tested this on a clean 'git clone ...' just making the short tag modification above to no avail...

handle custom primary key

when creating new tables, allow creation of a custom primary key, including custom type. i assume its possible for a custom primary key of varchar (?) or text (?).

need to handle array subdata

While i am processing my json data .Iam getting "need to handle array subdata" error is coming ..

Goal 1 Notes: Create Table and Insert Data

The idea is to take a json object, and insert auto-generate the table and/or columns necessary to insert the data into mysql.

given a json object and target table name:

if the table doesn't exist then:
- loop through the json object, collecting type information for each key value
- generate a table with the table name and columns
- start back at (1)
else, if the table exists, then:
- verify that the table contains columns for all of the keys in the json object
  - if not, then add the appropriate columns (never delete/rename), start back at 2
- determine the unique key of the json object "id" unless otherwise specified
- determine if a row with that id already exists,
  - if so, then update the row with the json object
  - otherwise insert a new row

if the JSON object contains other objects as its property values, then flatten them into columns, so:
{ "foo" : { "bar1" : "baz1", "bar2" : "baz2"} }
is equivalant to:
{"foo_bar1" : "baz1", "foo_bar2" : "baz2" }

if a property contains an array for a value, then each of those objects should be added to their own mysql table, with a foreign key to the original table's row. so:
{ "foo" : [{ "bar" : "baz1"}, {"bar" : "baz2"}] }

would auto generate a table tablename_foo, with foreign key column: foo_id that points to the original foo object. tablename_foo would also contain the data column bar, and 2 rows for each baz1 and baz2 would be inserted.

There is no DatabaseException class

/JSONtoMYSQL/lib/class.MySQLConn.php creates an instance of DatabaseException but there is no such class in the repo.

JSON-Data won't be processed completely (ignores sub-arrays)

Hi there,

I'm parsing data from the youtube API. In this case I got an array of items I'd like to parse:
this is the input for the json_decode

String input for json_decode:

when I call


$db->save($obj, "channel");

where will be only the fields:
id
title
description
publishedAt
country

Sub-Elements will currently be ignored without any warning.
It would be great if you could add/insert into another table for each sub element and handle the mapping.

Your software doesn't work

I am getting a NULL value from the class, but all files are found.
The return JSON object is fully populated with data.

<title>Analytics</title>

Dump by ID

addToClasspath(ROOT); $mysql = new MySQLConn(DATABASE_HOST, DATABASE_NAME, DATABASE_USER, DATABASE_PASS); $db = new JSONtoMYSQL($mysql); // create some json $obj = json_decode($output); // save it to a table $db->save($obj, "brandnewtable"); ?>

Enter the Object ID you would like for me to retrieve 'hearts' for.

Object ID :

Goal 3: Search table with JSON object

easily search for data matching an input JSON object. figure out how to easily support wildcard text search, and < > for numeric and date columns

Goal 4: Auto-Index

Try to auto-create indexes on columns based on the JSON data that populates the table, and based on the searches on a table. If a table is consistently searched on its start_date column, then auto-add an index on that column. Same for multi-column indexes.

"search, update, index, and validate tables with JSON" - How?

The example given works beautifully - however, when adding the same JSON data, the $db->save(...) method creates a duplicate in the resulting table. Is it possible to check for the row first and avoid duplicated entries - ie. if (!$db->find($json_object,"table") ...?

If someone could "flesh out" the example to include any other functions (search, update...), it would be hugely appreciated.

Validate it and remove any fields not on the table

This way the dev has the option to validate an object to a table, which'll add fields to the table, or validate the object against the table, which'll remove fields from the object
