This adapter saves state history into SQL DB.
Supports PostgreSQL, mysql, Microsoft SQL Server and sqlite.
You can leave port 0 if default port is desired.
### MS-SQL:
Use ```localhost\instance``` for host and check that TCP/IP connections are enabled.
https://msdn.microsoft.com/en-us/library/bb909712(v=vs.90).aspx
### SQLite:
is "file"-DB and cannot manage too many events. If you have a big amount of data use real DB, like PostgreSQL and co.
SQLite DB must not be installed extra. It is just a file on disk, but to install it you require build tools on your system. For linux, just write:
```
sudo apt-get install build-essential
```
For windows:
```
c:\>npm install --global --production windows-build-tools
```
And then reinstall the adapter, e.g:
```
cd /opt/yunkong2
yunkong2 stop sql
npm install yunkong2.sql --production
yunkong2 start sql
```
### MySQL:
You can install mysql on linux systems:
```
apt-get install mysql-server mysql-client
mysql -uroot -p
CREATE USER 'yunkong2'@'%' IDENTIFIED BY 'yunkong2';
GRANT ALL PRIVILEGES ON * . * TO 'yunkong2'@'%';
FLUSH PRIVILEGES;
```
If required edit */etc/mysql/my.cnf* to set bind to IP-Address for remote connect.
**Warning**: yunkong2 user is "admin". If required give limited rights to yunkong2 user.
## Structure of the DBs

## Custom queries
The user can execute custom queries on tables from javascript adapter:
```
sendTo('sql.0', 'query', 'SELECT * FROM datapoints', function (result) {
if (result.error) {
console.error(result.error);
} else {
// show result
console.log('Rows: ' + JSON.stringify(result.result));
}
});
```
Or get entries for the last hour for ID=system.adapter.admin.0.memRss
```
sendTo('sql.0', 'query', 'SELECT id FROM datapoints WHERE name="system.adapter.admin.0.memRss"', function (result) {
if (result.error) {
console.error(result.error);
} else {
// show result
console.log('Rows: ' + JSON.stringify(result.result));
var now = new Date();
now.setHours(-1);
sendTo('sql.0', 'query', 'SELECT * FROM ts_number WHERE ts >= ' + now.getTime() + ' AND id=' + result.result[0].id, function (result) {
console.log('Rows: ' + JSON.stringify(result.result));
});
}
});
```
## storeState
If you want to write other data into the InfluxDB you can use the build in system function **storeState**.
This function can also be used to convert data from other History adapters like History or SQL.
The given ids are not checked against the yunkong2 database and do not need to be set up there, but can only be accessed directly.
The Message can have one of the following three formats:
* one ID and one state object
* one ID and array of state objects
* array of multiple IDs with state objects
## Get history
Additional to custom queries, you can use build in system function **getHistory**:
```
var end = new Date().getTime();
sendTo('sql.0', 'getHistory', {
id: 'system.adapter.admin.0.memRss',
options: {
start: end - 3600000,
end: end,
aggregate: 'minmax' // or 'none' to get raw values
}
}, function (result) {
for (var i = 0; i < result.result.length; i++) {
console.log(result.result[i].id + ' ' + new Date(result.result[i].ts).toISOString());
}
});
```
## History Logging Management via Javascript
The adapter supports enabling and disabling of history logging via JavaScript and also retrieving the list of enabled datapoints with their settings.
### enable
The message requires to have the "id" of the datapoint.Additionally optional "options" to define the datapoint specific settings:
```
sendTo('sql.0', 'enableHistory', {
id: 'system.adapter.sql.0.memRss',
options: {
changesOnly: true,
debounce: 0,
retention: 31536000,
maxLength: 3,
changesMinDelta: 0.5,
aliasId: ""
}
}, function (result) {
if (result.error) {
console.log(result.error);
}
if (result.success) {
//successfull enabled
}
});
```
### disable
The message requires to have the "id" of the datapoint.
```
sendTo('sql.0', 'disableHistory', {
id: 'system.adapter.sql.0.memRss',
}, function (result) {
if (result.error) {
console.log(result.error);
}
if (result.success) {
//successfull enabled
}
});
```
### get List
The message has no parameters.
```
sendTo('sql.0', 'getEnabledDPs', {}, function (result) {
//result is object like:
{
"system.adapter.sql.0.memRss": {
"changesOnly":true,
"debounce":0,
"retention":31536000,
"maxLength":3,
"changesMinDelta":0.5,
"enabled":true,
"changesRelogInterval":0,
"aliasId": ""
}
...
}
});
```
