ESQL/C Parameter specification

Is there a reliable method of determining the number and types of parameters required by a dynamic SQL query passed to ESQL? The only references in the documentation and the samples seem to indicate that a priori information is required (or alterna- tively the query needs to be parsed) when passing parameters. I would like to be able to look at something analogous to the sql descriptor (or sqlda) syntax to extract this information. -- pekka@data.co.za Data Abstraction (Pty) Ltd Johannesburg, South Africa
