Tablestore:Write a single row

Prerequisites

Initialize a Tablestore client

Method

public PutRowResponse PutRow(PutRowRequest request)

Asynchronous method:

public Task<PutRowResponse> PutRowAsync(PutRowRequest request)

Sample code

The following example writes a row with primary key value "row1" to the "test_table" table.

try
{
    // Construct the primary key.
    PrimaryKey primaryKey = new PrimaryKey
    {
        { "id", new ColumnValue("row1") }
    };
    // Specify a condition for the write operation. 
    // RowExistenceExpectation.IGNORE skips the row existence check.
    Condition condition = new Condition(RowExistenceExpectation.IGNORE);

    // Call the PutRow method to write the row.
    PutRowRequest putRowRequest = new PutRowRequest("test_table", condition, primaryKey, null);
    PutRowResponse putRowResponse = client.PutRow(putRowRequest);
    Console.WriteLine($"* RequestId: {putRowResponse.RequestID}");
    Console.WriteLine($"* Read CU Cost: {putRowResponse.ConsumedCapacityUnit.Read}");
    Console.WriteLine($"* Write CU Cost: {putRowResponse.ConsumedCapacityUnit.Write}");
}
catch (Exception ex)
{
    Console.WriteLine($"Put row failed, exception: {ex.Message}");
}

• Add attribute columns.

  AttributeColumns columns = new AttributeColumns
  {
      { "col1", new ColumnValue("val1") }
  };
  
  // Create a PutRowRequest.
  PutRowRequest putRowRequest = new PutRowRequest("test_table", condition, primaryKey, columns);
