iobroker.sql
Advanced tools
==================================
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.
Use localhost\instance for host and check that TCP/IP connections are enabled.

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/iobroker
iobroker stop sql
npm install iobroker.sql --production
iobroker start sql
You can install mysql on linux systems:
apt-get install mysql-server mysql-client
mysql -uroot -p
CREATE USER 'iobroker‘@’%’ IDENTIFIED BY 'iobroker';
GRANT ALL PRIVILEGES ON * . * TO 'iobroker'@'%';
FLUSH PRIVILEGES;
If required edit /etc/mysql/my.cnf to set bind to IP-Address for remote connect.
Warning: iobroker user is "admin". If required give limited rights to iobroker user.
Default Database name is "iobroker", but it can be changed in configuration.

Values for states with type "number". ts means "time series".

| q | INTEGER | Quality as number. You can find description here |
Note: MS-SQL uses BIT, and others use BOOLEAN. SQLite uses for ts INTEGER and all others BIGINT.
Values for states with type "string".

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));
});
}
});
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 ioBroker 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:
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());
}
});
The adapter supports enabling and disabling of history logging via JavaScript and also retrieving the list of enabled datapoints with their settings.
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
}
}, function (result) {
if (result.error) {
console.log(result.error);
}
if (result.success) {
//successfull enabled
}
});
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
}
});
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
}
...
}
});
