# Update Rows

If a single row or multiple rows are to be updated with one or more column values in a table,
updateRows() method is used.

> **Note:** ROWDID should be set to update a row.

#### Sample Code Snippet 

**Package Imports**

```java
import com.zc.component.object.ZCObject; 
import com.zc.component.object.ZCRowObject; 
import com.zc.component.object.ZCTable;
```

```java
//Create a base Object Instance 
ZCObject object = ZCObject.getInstance(); 
//Get a Table Instance referring the table ID on base object 
ZCTable table = object.getTable(1510000000110121L); // replace table ID
//Create a List of RowObjects 
List<ZCRowObject>  rows = new ArrayList(); 
//Create row instances
ZCRowObject row1 = ZCRowObject.getInstance(); 
ZCRowObject row2 = ZCRowObject.getInstance(); 
//Set the updated value on the rows referring the ROWIDs 
row1.set("Name","Amelia S"); 
row1.set("Age", 19); 
row1.set("ROWID", 1510000000109113L);  // replace row id
row2.set("Name", "Walker Don"); 
row2.set("Age", 19); 
row2.set("ROWID", 1510000000109115L); // replace row id
//Add Rows to the List
rows.add(row1); 
rows.add(row2); 
//Update Multiple rows in table 
table.updateRows(rows);

```
