ArcSDE C-API 开发：添加新要素

基本步骤：

1. Connect to a database.

2. Initiate the insert statement on the stream.

3. For each row to be inserted
   {
      Set the data values.
      Insert row by executing statement.
   }

4. Disconnect from the database.

代码：

* Define the columns to be filled in on insert */

num_cols = 4;

attrs = (CHAR **) malloc (num_cols * sizeof(CHAR *));

attrs[0] = "city_name";

attrs[1] = "area";

attrs[2] = "population";

attrs[3] = "boundary";

/* Tell the stream that you are inserting new records into the table */

rc = SE_stream_insert_table (Stream, "cities", num_cols, attrs);

/* See Error handling section for check_error function code. */

check_error(NULL, Stream, rc, "SE_stream_insert_table");

/* For each record to be inserted into the table */

while (more data exists for insert;ldots;)

{

   rc = SE_stream_set_string (Stream, 1, city_name);

   check_error(NULL, Stream, rc, "SE_stream_set_string");

   rc = SE_stream_set_double (Stream, 2, area);

   check_error(NULL, Stream, rc, "SE_stream_set_double");

   rc = SE_stream_set_integer (Stream, 3, population);

   check_error(NULL, Stream, rc, "SE_stream_set_integer");

   rc = SE_stream_set_shape (Stream, 4, shape);

   check_error(NULL, Stream, rc, "SE_stream_set_shape");

   rc = SE_stream_execute (Stream);

   check_error(NULL, Stream, rc, "SE_stream_execute");

}
