**WARNING!!!** It's a legacy version of current library! *Do not use in release product!!*
|
# SQLEasy library
|
||||||
|
This library was written from simple work with databases. In current version supported next famous databases: sqlite3 and MySQL. In future, list with supported databases will be replenishing.
|
||||||
# SQLEasy.js
|
## Prepare to work
|
||||||
module for simple works from sqlite3 (JavaScript edition)
|
Before you use this module you must install it.
|
||||||
## Prepare for work (install from github)
|
```bash
|
||||||
Use npm from install in your project:
|
npm install sql-easy-lib --save
|
||||||
```bash
|
```
|
||||||
npm install sql-easy-lib
|
and you can include it!
|
||||||
```
|
```node
|
||||||
import database object in your project
|
const SQLEasy = require('sql-easy-lib');
|
||||||
``` javascript
|
```
|
||||||
const SQLEasy = require('sql-easy-lib');
|
## Tools and main objects
|
||||||
var database = new SQLEasy.database('/path/to/database.db');
|
Before work, you must know about twice main tools: **get_from_key** and **Request**.
|
||||||
```
|
```node
|
||||||
This object have 4 methods: add, remove, set, get
|
const SQLEasy = require('sql-easy-lib');
|
||||||
## Prepare for work (install from github)
|
|
||||||
My module use module **better-sqlite3**, you must download it.
|
var req = new SQLEasy.Request([{id: 1, value: 12}, {name: 'CirillaGif'}]);
|
||||||
```bash
|
/* This is boolean operation: "(id=1 AND value=12) OR (name=`CirillaGif`)" */
|
||||||
npm install better-sqlite3
|
var get_from_key = SQLEasy.tools.get_from_key;
|
||||||
```
|
/* get_from_key function, about him in down. */
|
||||||
from next, you can download folder of project, and load in folder "node_modules"
|
```
|
||||||
``` bash
|
**Request** use from create logic expression
|
||||||
cd node_modules
|
*example:*
|
||||||
git clone https://github.com/Nikiroy78/SQLEasy.js.git
|
```node
|
||||||
```
|
// ...
|
||||||
import database object in your project
|
new SQLEasy.Request([{id: 1, value: 12}, {name: 'CirillaGif'}]);
|
||||||
``` javascript
|
```
|
||||||
const SQLEasy = require('SQLEasy.js');
|
```mysql
|
||||||
var database = new SQLEasy.database('/path/to/database.db');
|
(id=1 AND value=12) OR (name=`CirillaGif`)
|
||||||
```
|
```
|
||||||
This object have 4 methods: add, remove, set, get
|
**get_from_key** use for more efficient queries from buffer variables.
|
||||||
## Methods of SQLEasy object
|
*example:*
|
||||||
### get
|
```node
|
||||||
This method getting date from included database
|
// Without use get_from_key
|
||||||
```javascript
|
const SQLEasy = require('sql-easy-lib');
|
||||||
const sqlite = require('SQLEasy.js');
|
var database = new SQLEasy.SQLite3_database('/path/to/database.db');
|
||||||
var database = sqlite.database('/path/to/database.db');
|
var rolesData = database.get('users').map(i => {
|
||||||
|
return {
|
||||||
console.log(database.get('table'));
|
user: i,
|
||||||
```
|
role_data: database.get('role', new SQLEasy.Request([{id: i.role}]))
|
||||||
output...
|
}
|
||||||
``` javascript
|
});
|
||||||
[{'ID': 0, 'content': 'content 1'}, {'ID': 1, 'content': 'other content'}, {'ID': 2, 'content': 'Content number 3 :)'}, {'ID': 3, 'content': 'etc.'}]
|
```
|
||||||
```
|
```node
|
||||||
|
// With use get_from_key
|
||||||
You can apply condition's settings from filt your data...
|
const SQLEasy = require('sql-easy-lib');
|
||||||
```javascript
|
var database = new SQLEasy.SQLite3_database('/path/to/database.db');
|
||||||
const sqlite = require('SQLEasy.js');
|
var roleData = database.get('role', new SQLEasy.Request([{id: i.role}]));
|
||||||
var database = sqlite.database('/path/to/database.db');
|
var rolesData = database.get('users').map(i => {
|
||||||
|
return {
|
||||||
console.log(database.get('table', [{'ID': 0}, {'content': 'etc.'}]));
|
user: i,
|
||||||
```
|
role_data: sqlite.get_from_key(roleData, new SQLEasy.Request([{id: i.role}]))
|
||||||
output...
|
}
|
||||||
``` javascript
|
});
|
||||||
[{'ID': 0, 'content': 'content 1'}, {'ID': 3, 'content': 'etc.'}]
|
```
|
||||||
```
|
## Methods of databases
|
||||||
Response show is...
|
In all databases methods is equally *(except for the connection)*.
|
||||||
```SQL
|
```node
|
||||||
SELECT * FROM table WHERE (ID=0) OR (content='etc.')
|
const SQLEasy = require('sql-easy-lib');
|
||||||
```
|
/* Method for connection sqlite3 database */
|
||||||
And you edit uploaded columns
|
var sqlite3 = new SQLEasy.SQLite3_database('/path/to/database.db');
|
||||||
```javascript
|
/* Method for connection MySQL database */
|
||||||
const sqlite = require('SQLEasy.js');
|
var mysql = new SQLEasy.MySQL_database({
|
||||||
var database = sqlite.database('/path/to/database.db');
|
host: "mysql.example.org",
|
||||||
|
user: "username",
|
||||||
console.log(database.get('table', [{'ID': 0}, {'content': 'etc.'}], 'content'));
|
password: "password"
|
||||||
```
|
});
|
||||||
output...
|
mysql.set_db("Example_db"); // setting database in server
|
||||||
``` javascript
|
```
|
||||||
[{'content': 'content 1'}, {'content': 'etc.'}]
|
*(for example, we use abstract database object):* **database**
|
||||||
```
|
```node
|
||||||
Response show is...
|
const SQLEasy = require('sql-easy-lib');
|
||||||
```SQL
|
|
||||||
SELECT content FROM table WHERE (ID=0) OR (content='etc.')
|
var database = new SQLEasy.AnyDatabase(args);
|
||||||
```
|
```
|
||||||
### add
|
### get
|
||||||
This is sql response
|
This is getting items from table:
|
||||||
```SQL
|
```mysql
|
||||||
INSERT
|
SELECT
|
||||||
```
|
```
|
||||||
Using add method in your code (from your simply, we used old date from last database).
|
*syntax:*
|
||||||
```javascript
|
```node
|
||||||
const sqlite = require('SQLEasy.js');
|
database.get(
|
||||||
var database = sqlite.database('/path/to/database.db');
|
'table_name',
|
||||||
|
new SQLEasy.Request([{param: 'value'}]), // Not required: ...WHERE (CONDITION) in request
|
||||||
database.add('table', [{'ID': 4, 'content': 'test example, from fucking tests :)'}])
|
'*' // Not required: Items in table
|
||||||
console.log(database.get('table'));
|
);
|
||||||
```
|
```
|
||||||
output...
|
```mysql
|
||||||
```javascript
|
SELECT * FROM table_name WHERE (param=`value`)
|
||||||
[{'ID': 0, 'content': 'content 1'}, {'ID': 1, 'content': 'other content'}, {'ID': 2, 'content': 'Content number 3 :)'}, {'ID': 3, 'content': 'etc.'}, {'ID': 4, 'content': 'test example, from fucking tests :)'}]
|
```
|
||||||
```
|
### set
|
||||||
### remove
|
This is set values in items in table:
|
||||||
Using remove method in your code (from your simply, we used old date from last database).
|
```mysql
|
||||||
```javascript
|
UPDATE .. SET
|
||||||
const sqlite = require('SQLEasy.js');
|
```
|
||||||
var database = sqlite.database('/path/to/database.db');
|
*syntax:*
|
||||||
|
```node
|
||||||
database.remove('table', {'ID': 4});
|
database.set(
|
||||||
console.log(database.get('table'));
|
'table_name',
|
||||||
```
|
new SQLEasy.Request([{param: 'value_require_edit'}]), // Required: ...WHERE (CONDITION) in request
|
||||||
output...
|
[{param: 'value'}] // Required: Items in table
|
||||||
```javascript
|
);
|
||||||
[{'ID': 0, 'content': 'content 1'}, {'ID': 1, 'content': 'other content'}, {'ID': 2, 'content': 'Content number 3 :)'}, {'ID': 3, 'content': 'etc.'}]
|
```
|
||||||
```
|
```mysql
|
||||||
### set
|
UPDATE table_name SET param=`value` WHERE (param=`value_require_edit`)
|
||||||
Using set method in your code (from your simply, we used old date from last database).
|
```
|
||||||
```javascript
|
### remove
|
||||||
const sqlite = require('SQLEasy.js');
|
This method for remove items into database.
|
||||||
var database = sqlite.database('/path/to/database.db');
|
```mysql
|
||||||
|
DELETE
|
||||||
database.set('table', {'ID': 3}, {'content': 'edited'}); // First param - index key, found param - edit content...
|
```
|
||||||
console.log(database.get('table'));
|
*syntax:*
|
||||||
```
|
```node
|
||||||
output...
|
database.remove(
|
||||||
```javascript
|
'table_name',
|
||||||
[{'ID': 0, 'content': 'content 1'}, {'ID': 1, 'content': 'other content'}, {'ID': 2, 'content': 'Content number 3 :)'}, {'ID': 3, 'content': 'edited'}]
|
new SQLEasy.Request([{param: 'value'}]) // Required: ...WHERE (CONDITION) in request
|
||||||
```
|
);
|
||||||
### execute
|
```
|
||||||
This is important method from execute your SQL script in your code.
|
```mysql
|
||||||
Using method **execute** in test code (from your simply, we used old date from last database).
|
DELETE FROM table_name WHERE (param=`value_require_edit`)
|
||||||
```javascript
|
```
|
||||||
const sqlite = require('SQLEasy.js');
|
### add
|
||||||
var database = sqlite.database('/path/to/database');
|
Method for add items into database.
|
||||||
|
```mysql
|
||||||
var data = database.execute('SELECT * FROM table');
|
INSERT
|
||||||
console.log(data);
|
```

```
|
*syntax:*
|
||||||
output...
|
```node
|
||||||
```javascript
|
database.remove(
|
||||||
[{'ID': 0, 'content': 'content 1'}, {'ID': 1, 'content': 'other content'}, {'ID': 2, 'content': 'Content number 3 :)'}, {'ID': 3, 'content': 'etc.'}]
|
'table_name',
|
||||||
```
|
[{param: 'value'}] // Required: ... Rows what you add in table.
|
||||||
### getIndex
|
);
|
||||||
Use this method from getting index value.
|
```
|
||||||
```javascript
|
```mysql
|
||||||
const sqlite = require('SQLEasy.js');
|
INSERT INTO table_name (param) VALUES (`value`)
|
||||||
var database = sqlite.database('/path/to/database.db');
|
|
||||||
|
|
||||||
console.log(database.get('table'));
|
|
||||||
console.log(database.getIndex('table', 'ID'));
|
|
||||||
```
|
|
||||||
output...
|
|
||||||
```javascript
|
|
||||||
[{'ID': 0, 'content': 'content 1'}, {'ID': 1, 'content': 'other content'}, {'ID': 3, 'content': 'Content number 3 :)'}, {'ID': 4, 'content': 'edited'}]
|
|
||||||
2
|
|
||||||
```
|
|
||||||
## Other functions that you can use in this module
|
|
||||||
### get_from_key
|
|
||||||
This function needs from works data in buffer.
|
|
||||||
The main advantage of this method is that you do not need to request data from the database every time, it is enough to use the data uploaded to memory:
|
|
||||||
```javascript
|
|
||||||
// Legacy method!
|
|
||||||
const sqlite = require('SQLEasy.js');
|
|
||||||
var database = sqlite.database('/path/to/database.db');
|
|
||||||
var rolesData = database.get('users').map(i => {
|
|
||||||
return {
|
|
||||||
user: i,
|
|
||||||
role_data: database.get('role', [{id: i.role}])
|
|
||||||
}
|
|
||||||
});
|
|
||||||
```
|
|
||||||
```javascript
|
|
||||||
// New method!
|
|
||||||
const sqlite = require('SQLEasy.js');
|
|
||||||
var database = sqlite.database('/path/to/database.db');
|
|
||||||
var roleData = database.get('role', [{id: i.role}]);
|
|
||||||
var rolesData = database.get('users').map(i => {
|
|
||||||
return {
|
|
||||||
user: i,
|
|
||||||
role_data: sqlite.get_from_key(roleData, [{id: i.role}])
|
|
||||||
}
|
|
||||||
});
|
|
||||||
```
|
