Informix Stored Procedure Blobs into CF

Question

New CF user here. I'm trying to use Informix Stored
Procedures to return blobs to CF. When using cfquery, all worked
fine, but it seems I can only return the non-blob fields when using
stored procedures. According to the documentation, I can define a
pointer (references text) in the stored procedure, but I don't know
how to get the blob to display in CF since I cannot use it in the
RETURNING section of the procedure, Any thoughts to also get the
blob in additional to the 5 other character values that are
returned just fine? Thanks in advance.

Answer 1

Better to use a PL/SQL stored
procedure than a
function, as "older" versions of ColdFusion could not handle
the retun value from an Oracle function. Not sure about 6.1, but
you can use them with MX7, but you have to capture your return code
in a variable named cfstoredproc.StatusCode, such as below:
<cfstoredproc procedure="one_fucntion.getosuser"
returncode="yes" datasource="gcadmin" debug="yes">
<cfprocparam cfsqltype="cf_sql_integer" type="IN"
value="2" >
</cfstoredproc>
<cfoutput>#cfstoredproc.statusCode#</cfoutput>
I would rewrite your PL/SQL SP as a procedure with an OUT
parameter that you could capture in a CFPROCPARAM.
Also, you would only use CFPROCRESULT if you were returning
the results of a query that you had selected into a referrence
cursor in your proc (OPEN out_ref_cursor FOR SELECT...... etc.),
but you would have to contain your procedure in a package and have
a ref cursor type declared globally , etc. Your use of CFPROCRESULT
is not necessary to return a single value from a procedure, only a
CFPROCPARAM of type="out".
Bottom line, as written, what you have isn't really even
close... sorry.
