Tablestore:Batch update data

Usage notes

• If the server detects a parameter error in any operation, all operations in the request fail.

• A single batch update operation supports up to 200 rows. The total data size of all rows must not exceed 4 MB.

Prerequisites

Initialize the Tablestore client

Method

public function batchWriteRow(array $request)

Examples

The following code inserts a row into the test_table table.

$table = array (
    'table_name' => 'test_table',
    'rows' => array (
        array (
            'operation_type' => OperationTypeConst::CONST_PUT,
            'primary_key' => array ( array('id', 'row1') )
        )
    )
);
$request = array(
    'tables' => array (
        $table
    )
);

try {
    // Call the batchWriteRow method to perform batch data operations.
    $response = $client->batchWriteRow ($request);

     // Process the response.
    foreach ($response['tables'] as $tableGroup) {
        foreach ($tableGroup['rows'] as $row) {
            if (!$row['is_ok']) {
                echo "TableName: {$tableGroup['table_name']}. ErrorCode: {$row['error']['code']}. ErrorMessage: {$row['error']['message']} \n";
            }
        }
    }
} catch (Exception $e){
    echo 'Batch write row failed.';
}

Refer to the following examples for different operation types.

• PutRowItem: Insert a row.

  $table = array (
      'table_name' => 'test_table',
      'rows' => array (
          array (
              'operation_type' => OperationTypeConst::CONST_PUT,
              'primary_key' => array ( array('id', 'row1') )
          )
      )
  );

  Insert a row with attribute columns.

  $table = array (
      'table_name' => 'test_table',
      'rows' => array (
          array (
              'operation_type' => OperationTypeConst::CONST_PUT,
              'primary_key' => array ( array('id', 'row1') ),
              'attribute_columns' => array (
                  array('col1', 'val1'),
                  array('col2', 'val2', null, intval(microtime(true) * 1000))
              )
          )
      )
  );

• UpdateRowItem: Update a row by modifying attribute column values, adding attribute columns, or deleting a specific version or all versions of an attribute column.

  $table = array (
      'table_name' => 'test_table',
      'rows' => array (
          array (
              'operation_type' => OperationTypeConst::CONST_UPDATE,
              'primary_key' => array ( array('id', 'row1') ),
              'update_of_attribute_columns'=> array(
                  'PUT' => array ( array('col1', 'changed_val1') )
              ),
              // A condition is required to update a row. RowExistenceExpectation.IGNORE skips the row existence check.
              'condition' => RowExistenceExpectationConst::CONST_IGNORE
          )
      )
  );

  Add or delete attribute columns when updating a row.

  $table = array (
      'table_name' => 'test_table',
      'rows' => array (
          array (
              'operation_type' => OperationTypeConst::CONST_UPDATE,
              'primary_key' => array ( array('id', 'row1') ),
              'update_of_attribute_columns'=> array(
                  'PUT' => array ( 
                      // Add an attribute column.
                      array('col3', 'val3'),
                      // Add an attribute column with a custom version number.
                      array('col4', 'val4', null, intval(microtime(true) * 1000))
                  ),
                  // Delete an attribute column.
                  'DELETE_ALL' => array('col2')
              ),
              // A condition is required to update a row. RowExistenceExpectation.IGNORE skips the row existence check.
              'condition' => RowExistenceExpectationConst::CONST_IGNORE
          )
      )
  );

• DeleteRowItem: Delete a row.

  $table = array (
      'table_name' => 'test_table',
      'rows' => array (
          array (
              'operation_type' => OperationTypeConst::CONST_DELETE,
              'primary_key' => array ( array('id', 'row1') ),
              // A condition is required to delete a row. RowExistenceExpectation.IGNORE skips the row existence check.
              'condition' => RowExistenceExpectationConst::CONST_IGNORE
          )
      )
  );
