odbc_binmode - Handling of binary column data

SYNOPSIS

       bool odbc_binmode (resource  $result_id, int  $mode)

DESCRIPTION

	Enables handling of binary column data. ODBC SQL types affected are BINARY, VARBINARY, and LONGVARBINARY.

	When  binary  SQL  data  is converted to character C data, each byte (8 bits) of source data is represented as two ASCII characters. These
       characters are the ASCII character representation of the number in its hexadecimal form. For example, a binary  00000001  is  converted	to
       "01" and a binary 11111111 is converted to "FF".

       LONGVARBINARY handling

	If odbc_fetch_into(3) is used, passthru means that an empty string is returned for these columns.

PARAMETERS

	      o $result_id
		- The result identifier.  If $result_id is 0, the settings apply as default for new results.

	      Note

		      Default  for longreadlen is 4096 and $mode defaults to ODBC_BINMODE_RETURN. Handling of binary long columns is also affected
		     by odbc_longreadlen(3).

	      o $mode
		- Possible values for $mode are:

		     o ODBC_BINMODE_PASSTHRU: Passthru BINARY data

		     o ODBC_BINMODE_RETURN: Return as is

		     o ODBC_BINMODE_CONVERT: Convert to char and return

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

IFX_FETCH_ROW(3)							 1							  IFX_FETCH_ROW(3)

ifx_fetch_row - Get row as an associative array

SYNOPSIS

       array ifx_fetch_row (resource  $result_id, [mixed  $position])

DESCRIPTION

	Fetches one row of data from the result associated with the specified result identifier.

	Subsequent calls to ifx_fetch_row(3) would return the next row in the result set, or FALSE if there are no more rows.

PARAMETERS

	      o $result_id
		-$result_id is a valid resultid returned by ifx_query(3) or ifx_prepare(3) (select type queries only!).

	      o $position
		-  An  optional  parameter  for  a "fetch" operation on "scroll" cursors: NEXT, PREVIOUS, CURRENT, FIRST, LAST or a number. If you
		specify a number, an "absolute" row fetch is executed. This parameter is optional, and only valid for SCROLL cursors.

RETURN VALUES

	Returns an associative array that corresponds to the fetched row, or FALSE if there are no more rows.

	Blob columns are returned as integer blob id values for use in ifx_get_blob(3) unless you have used ifx_textasvarchar(1) or ifx_byteasvar-
       char(1), in which case blobs are returned as string values.

EXAMPLES

       Example #1

	      Informix fetch rows

	      <?php
	      $rid = ifx_prepare ("select * from emp where name like " . $name,
				   $connid, IFX_SCROLL);
	      if (! $rid) {
		  /* ... error ... */
	      }
	      $rowcount = ifx_affected_rows($rid);
	      if ($rowcount > 1000) {
		  printf ("Too many rows in result set (%d)
<br />", $rowcount);
		  die ("Please restrict your query<br />
");
	      }
	      if (! ifx_do ($rid)) {
		 /* ... error ... */
	      }
	      $row = ifx_fetch_row ($rid, "NEXT");
	      while (is_array($row)) {
		  for (reset($row); $fieldname=key($row); next($row)) {
		      $fieldvalue = $row[$fieldname];
		      printf ("%s = %s,", $fieldname, $fieldvalue);
		  }
		  printf("
<br />");
		  $row = ifx_fetch_row($rid, "NEXT");
	      }
	      ifx_free_result ($rid);
	      ?>
