   (PHP 3>= 3.0.4, PHP 4 )
   ifx_prepare -- Prepare an SQL-statement for execution

Description

   int ifx_prepare ( string query, int conn_id [, int cursor_def, mixed
   blobidarray])

   Returns an integer result_id for use by ifx_do(). Sets affected_rows
   for retrieval by the ifx_affected_rows() function.

   Prepares query on connection conn_id. For "select-type" queries a
   cursor is declared and opened. The optional cursor_type 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.

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

   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.

   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).
