+# Chapter 4 Operation Manual
+# IoTDB SQL Statement
+In this part, we will introduce you IoTDB's Query Language. IoTDB offers you a
SQL-like query language for interacting with IoTDB, the query language can be
devided into 4 major parts:
+
+* Schema Statement: statements about schema management are all listed in this
section.
+* Data Management Statement: statements about data management (such as: data
insertion, data query, etc.) are all listed in this section.
+* Database Management Statement: statements about database management and
authentication are all listed in this section.
+* Functions: functions that IoTDB offers are all listed in this section.
+
+All of these statements are write in IoTDB's own syntax, for details about the
syntax composition, please check the `Reference` section.
+
+## IoTDB Query Statement
+
+
+### Schema Statement
+
+* Set Storage Group
+
+``` SQL
+SET STORAGE GROUP TO

root.ln.wf01.wt01.temperature
+Eg: IoTDB > DELETE TIMESERIES root.ln.wf01.wt01.*
+```

+* Show All Timeseries Statement
+
+```
+SHOW TIMESERIES
+Eg: IoTDB > SHOW TIMESERIES

timeseries in JDBC, please use `DataBaseMetadata` interface.
+```
+
+* Show Specific Timeseries Statement
+
+```
+SHOW TIMESERIES
+Eg: IoTDB > SHOW TIMESERIES root
+Eg: IoTDB > SHOW TIMESERIES root.ln
+Eg: IoTDB > SHOW TIMESERIES root.ln.*.*.status
+Eg: IoTDB > SHOW TIMESERIES root.ln.wf01.wt01.status
+Note: The path can be prefix path, star path or timeseries path
+Note: This statement can be used in IoTDB Client and JDBC.
+```
+
+* Show Storage Group Statement
+
+```
+SHOW STORAGE GROUP
+Eg: IoTDB > SHOW STORAGE GROUP
+Note: This statement can be used in IoTDB Client and JDBC.
+```
+
+### Data Management Statement
+
+* Insert Record Statement
+
+```
+INSERT INTO LPAREN TIMESTAMP COMMA [COMMA ]*
RPAREN VALUES LPAREN , [COMMA ]* RPAREN
+Sensor : Identifier
+Eg: IoTDB > INSERT INTO root.ln.wf01.wt01(timestamp,status)
values(150946560,true)
+Eg: IoTDB > INSERT INTO root.ln.wf01.wt01(timestamp,status) VALUES(NOW(),
false)
+Eg: IoTDB > INSERT INTO root.ln.wf01.wt01(timestamp,temperature)
VALUES(2017-11-01T00:17:00.000+08:00,24.22028)
+Eg: IoTDB > INSERT INTO root.ln.wf01.wt01(timestamp, status, temperature)
VALUES (150946668, false, 20.060787);
+Note: the statement needs to satisfy this constraint: + =
+Note: The order of Sensor and PointValue need one-to-one correspondence
+```
+
+* Update Record Statement
+
+```
+UPDATE SET WHERE
+UpdateClause:
+SetClause:
+SetExpression: EQUAL
+WhereClause : [(AND | OR) ]*
+Condition : [(AND | OR) ]*
+Expression : [NOT | !]? TIME PrecedenceEqualOperator
+Eg: IoTDB > UPDATE root.ln.wf01.wt01 SET temperature = 23 WHERE time < NOW()
and time > 2017-11-1T00:15:00+08:00
+Note: the statement needs to satisfy this constraint: + =
+```
+
+* Delete Record Statement
+
+```
+DELETE FROM [COMMA ]* WHERE TIME LESSTHAN
+Eg: DELETE FROM root.ln.wf01.wt01.temperature WHERE time <
2017-11-1T00:05:00+08:00
+Eg: DELETE FROM root.ln.wf01.wt01.status, root.ln.wf01.wt01.temperature WHERE
time < NOW()
+Eg: DELETE FROM root.ln.wf01.wt01.* WHERE time < 150946614
+```
+
+* Select Record Statement
+
+```
+SELECT FROM [WHERE ]?
+SelectClause : (COMMA )*
+SelectPath : LPAREN RPAREN |
+FUNCTION : ‘COUNT’ , ‘MIN_TIME’, ‘MAX_TIME’, ‘MIN_VALUE’, ‘MAX_VALUE’

+# IoTDB-Grafana
+
+This project provides a connector which reads data from IoTDB and sends to
Grafana(https://grafana.com/). Before you use this tool, make sure Grafana and
IoTDB are correctly installed and started.
+
+## Grafana installation
+
+### Install Grafana
+
+* Download url: https://grafana.com/grafana/download
+* version >= 4.4.1
+
+### Install data source plugin
+
+* plugin name: simple-json-datasource
+* Download url: https://github.com/grafana/simple-json-datasource
+
+After downloading this plugin, you can use the grafana-cli tool to install
SimpleJson from the commandline:
+
+```
+grafana-cli plugins install grafana-simple-json-datasource
+```
+
+Alternatively, you can manually download the .zip file and unpack it into your
grafana plugins directory.
+
+* `{grafana-install-directory}\data\plugin\` (Windows)
+* `/var/lib/grafana/plugins` (Linux)
+* `/usr/local/var/lib/grafana/plugins`(Mac)
+
+### Start Grafana
+If you use Unix, Grafana will auto start after installing, or you can run
`sudo service grafana-server start` command. See more information
[here](http://docs.grafana.org/installation/debian/).
+
+If you use Mac and `homebrew` to install Grafana, you can use `homebrew` to
start Grafana.
+First make sure homebrew/services is installed by running `brew tap
homebrew/services`, then start Grafana using: `brew services start grafana`.
+See more information [here](http://docs.grafana.org/installation/mac/).
+
+If you use Windows, start Grafana by executing grafana-server.exe, located in
the bin directory, preferably from the command line. See more information
[here](http://docs.grafana.org/installation/windows/).
