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.
