This extension's purpose is to make the SQLite scripting more easier for anyone. Just look at the INC file which is listed below.

PHP Code:

/** Does a query.
 *
 * @param Query                The query to execute.
 * @param Select            Set it true whether the query contains "SELECT" word.
 *
 * @return                    The number of rows selected, if any.
 */
native /* unsigned int */    Database_Query(Query[], bool:Select = false);

/** Retrieves a result.
 *
 * @param Row                The row to pick result from.
 * @param Column            The column to pick result from.
 * @param Buffer            The variable to store result in.
 * @param Size                The variable that represents the buffer size.
 *
 * @return                    The result converted as integer.
 */
native /* signed int */        Database_Get(Row, Column, Buffer[], Size);

/** Makes a string safe.
 *
 * @param String            The string to make safe.
 * @param Character            The character to replace bad characters as '\\', '`', '"' or '\''.
 *
 * @return                    True if success or false if error.
 */
native /* bool */            bool:Database_Safe(String[], Character = '*'); 


An example of plugin may be the one listed below.

PHP Code:

#include amxmodx
#include amxmisc
#include database

public plugin_init()
{
  register_plugin("Last Played Maps", "1.0", "Hattrick (Claudiu HKS)");

  Database_Query("CREATE TABLE IF NOT EXISTS Maps (Name TEXT, UnixTimeStamp NUMERIC)");

  new Map[32], Buffer[256];
  get_mapname(Map, sizeof(Map) - 1);

  formatex(Buffer, sizeof(Buffer) - 1, "INSERT INTO Maps VALUES ('%s', %d)", Map, get_systime());

  Database_Query(Buffer);

  register_concmd("amx_lastmaps", "CmdLastMaps", ADMIN_MAP, "- displays the last played maps");
}

public CmdLastMaps(Client, Level, Command)
{
  if (!cmd_access(Client, Level, Command, 1))
  {
    return PLUGIN_HANDLED;
  }

  console_print(Client, "^nThe last played maps were:^n");

  static Count = 0, Iterator = 0, Map[32];

  Count = Database_Query("SELECT Name FROM Maps ORDER BY UnixTimeStamp DESC LIMIT 15", true);

  if (Count)
  {
    for (Iterator = 0; Iterator < Count; Iterator++)
    {
      if (Iterator == 0)
      {
        RemDatabase_Get(Iterator, 0, Map, sizeof(Map) - 1);

        console_print(Client, "%s (current)", Map);
      }

      else
      {
        RemDatabase_Get(Iterator, 0, Map, sizeof(Map) - 1);

        console_print(Client, Map);
      }
    }
  }

  else
  {
    /* I can't believe I reached here... */
    console_print(Client, "Unfortunately, there were no maps played yet.");
  }

  return PLUGIN_HANDLED;
} 


How to use Database_Get native?

For example, if you execute the next query while having 5,000 rows into your table: SELECT Apples, Oranges FROM Fruits LIMIT 2

There will be two rows selected, because LIMIT is 2.
There will be two columns selected, because you select both Apples and Oranges.

So, you will use Database_Get with Row parameter 0 and then with Row parameter 1.
Also, with Column parameter 0 and then with Column parameter 1.
