ifx_prepare - Prepare an SQL-statement for execution

SYNOPSIS

       resource ifx_prepare (string  $query, resource  $link_identifier, [int  $cursor_def], mixed  $blobidarray)

DESCRIPTION

	Prepares a $query for later use with ifx_do(3).

	For "select-type" queries a cursor is declared and opened. Non-select queries are "execute immediate".

	For either query type the number of (estimated or real) affected rows is saved for retrieval by ifx_affected_rows(3).

	If  the contents of the TEXT (or BYTE) column allow it, you can also use ifx_textasvarchar(1) and ifx_byteasvarchar(1). This allows you to
       treat TEXT (or BYTE) columns just as if they were ordinary (but long) VARCHAR columns for select queries, and you don't need to bother with
       blob id's.

	With  ifx_textasvarchar(0)  or ifx_byteasvarchar(0) (the default situation), select queries will return BLOB columns as blob id's (integer
       value). You can get the value of the blob as a string or file with the blob functions (see below).

PARAMETERS

	      o $query
		- The query string.

	      o $link_identifier
		- The link identifier.

	      o $cursor_def
		- This optional parameter allows you to make this a scroll and/or hold cursor. It's  a	bitmask  and  can  be  either  IFX_SCROLL,
		IFX_HOLD, or both or'ed together.

	      o $blobidarray
		-  If  you  have BLOB (BYTE or TEXT) columns in the query, you can add a $blobidarray parameter containing the corresponding "blob
		ids", and you should replace those columns with a "?" in the query text.

RETURN VALUES

	Returns a valid result identifier for use by ifx_do(3), or FALSE on errors.

fbsql_read_blob - Read a BLOB from the database

SYNOPSIS

       string fbsql_read_blob (string  $blob_handle, [resource	$link_identifier])

DESCRIPTION

	Reads BLOB data from the database.

	If  a select statement contains BLOB and/or CLOB columns FrontBase will return the data directly when data is fetched. This default behav-
       ior can be changed with fbsql_set_lob_mode(3) so the fetch functions will return handles to BLOB and CLOB data. If a handle  is	fetched  a
       user must call fbsql_read_blob(3) to get the actual BLOB data from the database.

PARAMETERS

	      o $blob_handle
		- A BLOB handle, returned by fbsql_create_blob(3).

	      o $
		link_identifier  -A FrontBase link identifier returned by fbsql_connect(3) or fbsql_pconnect(3).If optional and not specified, the
		function will try to find an open link to the FrontBase server and if no such link is found it	will  try  to  create  one  as	if
		fbsql_connect(3) was called with no arguments.

RETURN VALUES

	Returns a string containing the specified BLOB data.

EXAMPLES

       Example #1

	      fbsql_read_blob(3) example

	      <?php
	      $link = fbsql_pconnect("localhost", "_SYSTEM", "secret")
		  or die("Could not connect");
	      $sql = "SELECT BLOB_COLUMN FROM BLOB_TABLE;";
	      $rs = fbsql_query($sql, $link);
	      $row_data = fbsql_fetch_row($rs);
	      // $row_data[0] will now contain the blob data for the first row
	      fbsql_free_result($rs);

	      $rs = fbsql_query($sql, $link);
	      fbsql_set_lob_mode($rs, FBSQL_LOB_HANDLE);
	      $row_data = fbsql_fetch_row($rs);
	      // $row_data[0] will now contain a handle to the BLOB data in the first row
	      $blob_data = fbsql_read_blob($row_data[0]);
	      fbsql_free_result($rs);

	      ?>
