+# Data Insertion & Update
+
+## 1. Data Insertion
+
+### 1.1 Syntax
+
+In IoTDB, data insertion follows the general syntax:
+
+```SQL
+INSERT INTO <TABLE_NAME> [(COLUMN_NAME[, COLUMN_NAME]*)]? VALUES (COLUMN_VALUE[, COLUMN_VALUE]*)
+```
+
+**Basic Constraints**:
+
+1. Tables cannot be automatically created using `INSERT` statements.
+2. Columns not specified in the `INSERT` statement will automatically be filled with `null`.
+3. If no timestamp is provided, the system will use the current time (`now()`).
+4. If a column value does not exist for the identified device, the insertion will overwrite any existing `null` values with the new data.
+5. If a column value already exists for the identified device, a new insertion will update the column with the new value.
+6. For duplicate timestamps:
+   1. Columns with `null` values at the original timestamp will be updated.
+   2. Columns with non-`null` values at the original timestamp will retain their original values.
+
+Since attributes generally do not change over time, it is recommended to update attribute values using the `UPDATE` statement described below，Please refer to the following [Data Update](#2-data-updates).
+
+<div style="text-align: center;">
+  <img src="/img/%E6%95%B0%E6%8D%AE%E5%86%99%E5%85%A5%E8%8B%B1%E6%96%87.png" alt="" style="width: 70%;"/>
+</div>
+
+
+### 1.2 Automatically Create Tables via Session Insertion
+
+When inserting data via the Session API, IoTDB can automatically create table structures based on the data insertion request, eliminating the need for manual table creation.
+
+**Example:**
+
+```Java
+try (ITableSession session =
+    new TableSessionBuilder()
+        .nodeUrls(Collections.singletonList("127.0.0.1:6667"))
+        .username("root")
+        .password("root")
+        .build()) {
+
+  session.executeNonQueryStatement("CREATE DATABASE db1");
+  session.executeNonQueryStatement("use db1");
+
+  // Insert data without manually creating the table
+  List<String> columnNameList =
+      Arrays.asList("region_id", "plant_id", "device_id", "model", "temperature", "humidity");
+  List<TSDataType> dataTypeList =
+      Arrays.asList(
+          TSDataType.STRING,
+          TSDataType.STRING,
+          TSDataType.STRING,
+          TSDataType.STRING,
+          TSDataType.FLOAT,
+          TSDataType.DOUBLE);
+  List<Tablet.ColumnCategory> columnTypeList =
+      new ArrayList<>(
+          Arrays.asList(
+              Tablet.ColumnCategory.TAG,
+              Tablet.ColumnCategory.TAG,
+              Tablet.ColumnCategory.TAG,
+              Tablet.ColumnCategory.ATTRIBUTE,
+              Tablet.ColumnCategory.FIELD,
+              Tablet.ColumnCategory.FIELD));
+  Tablet tablet = new Tablet("table1", columnNameList, dataTypeList, columnTypeList, 100);
+  for (long timestamp = 0; timestamp < 100; timestamp++) {
+    int rowIndex = tablet.getRowSize();
+    tablet.addTimestamp(rowIndex, timestamp);
+    tablet.addValue("region_id", rowIndex, "1");
+    tablet.addValue("plant_id", rowIndex, "5");
+    tablet.addValue("device_id", rowIndex, "3");
+    tablet.addValue("model", rowIndex, "A");
+    tablet.addValue("temperature", rowIndex, 37.6F);
+    tablet.addValue("humidity", rowIndex, 111.1);
+    if (tablet.getRowSize() == tablet.getMaxRowNumber()) {
+      session.insert(tablet);
+      tablet.reset();
+    }
+  }
+  if (tablet.getRowSize() != 0) {
+    session.insert(tablet);
+    tablet.reset();
+  }
+}
+```
+
+After execution, you can verify the table creation using the following command:
+
+```SQL
+IoTDB> desc table1
++-----------+---------+-----------+
+| ColumnName| DataType|   Category|
++-----------+---------+-----------+
+|       time|TIMESTAMP|       TIME|
+|  region_id|   STRING|        TAG|
+|   plant_id|   STRING|        TAG|
+|  device_id|   STRING|        TAG|
+|      model|   STRING|  ATTRIBUTE|
+|temperature|    FLOAT|      FIELD|
+|   humidity|   DOUBLE|      FIELD|
++-----------+---------+-----------+
+```
+
+### 1.3 Specified Column Insertion
+
+It is possible to insert data for specific columns. Columns not specified will remain `null`.
+
+**Example:**
+
+```SQL
+insert into table1("region", "plant_id", "device_id", Time, "temperature", "displacement") values ('Hamburg', '3001', '3', 4, 90.0, 1200.0)
+
+
+insert into table1("region", "plant_id", "device_id", Time, "temperature") values ('Hamburg, '3001', '3', 5, 90.0)
+```
+
+### 1.4 Null Value Insertion
+
+You can explicitly set `null` values for tag columns, attribute columns, and field columns.
+
+**Example**:
+
+Equivalent to the above partial column insertion.
+
+```SQL
+# Equivalent to the example above
+insert into table1("region", "plant_id", "device_id", "model", "maintenance_cycle", Time, "temperature", "displacement") values ('Hamburg', '3001', '3', null, null, 4, 90.0, 1200.0)
+
+insert into table1("region", "plant_id", "device_id", "model", "maintenance_cycle", Time, "temperature", "displacement") values ('Hamburg', '3001', '3', null, null, 5, 90.0, null)
+```
+
+If no tag columns are included, the system will automatically create a device with all tag column values set to `null`.
+
+> **Note:** This operation will not only automatically populate existing tag columns in the table with `null` values but will also populate any newly added tag columns with `null` values in the future.
+
+### 1.5 Multi-Row Insertion
+
+IoTDB supports inserting multiple rows of data in a single statement to improve efficiency.
+
+**Example**:
+
+```SQL
+insert into table1
+values
+('Frankfurt', '3001', '3', '1', '10', 4, 90.0, 1200.0)
+('Frankfurt', '3001', '3', '1', '10', 5, 90.0, 1200.0)
+
+
+insert into table1
+("region", "plant_id", "device_id", Time, "temperature", "displacement")
+values
+('Frankfurt', '3001', '3', 4, 90.0, 1200.0)
+('Frankfurt', '3001', '3', 5, 90.0, 1200.0)
+```
+
+#### Notes
+
+- Referencing non-existent columns in SQL will result in an error code `COLUMN_NOT_EXIST(616)`.
+- Data type mismatches between the insertion data and the column's data type will result in an error code `DATA_TYPE_MISMATCH(614)`.
+
+
+## 2. Data Updates
+
+### 2.1 Syntax
+
+```SQL
+UPDATE <TABLE_NAME> SET updateAssignment (',' updateAssignment)* (WHERE where=booleanExpression)?
+
+updateAssignment
+    : identifier EQ expression
+    ;
+```
+
+**Note:**
+
+- Updates are allowed only on `ATTRIBUTE` columns.
+- `WHERE` conditions:
+  - Can only include `TAG` and `ATTRIBUTE` columns; `FIELD` and `TIME` columns are not allowed.
+  - Aggregation functions are not supported.
+- The result of the `SET` assignment expression must be a `string` type and follow the same constraints as the `WHERE` clause.
+
+**Example**:
+
+```SQL
+update table1 set b = a where substring(a, 1, 1) like '%'
+```
