ExecSQL() Error: "No value for parameter '[^[:digit:]]*'"

G'day all...

We are converting a working application from the ZeosLib data access components to pgExpress with Devart drivers.

We have a problem with the Devart pgExpress drivers throwing an error on a call to TSQLQUery.ExecSQL(). This query evaluates perfectly in pgAdmin, and previously when using the ZeosLib data access components. All we are doing is setting the SQLQUery.SQL.Text property and calling ExecSQL(), and there are no event handlers or parameters set up on the SQLQuery object.

The error is:
    No value for parameter '[^[:digit:]]*'

The text in the error appears to be some kind of regular expression and it does not appear anywhere in the query. It looks to me like it's coming from some failed parsing operation in dbExpress/Devart.

The query text is as follows:

Code: Select all
set search_path = aull, breedplan, public;
set session authorization sk;

/* if the header record doesn't already exist for this calving year, create it */

insert into membership_years (soc_code, members_key, membership_year,
           membership_rec_type, membership_type, membership_status,
           date_assessed,  membership_key)

I am continuing to investigate this and I am attempting to create a simple test case, but can anyone shed any light on where the error is coming from?

I should add that this is occuring in Delphi 7. The reason for the change to Devart is that we are preparing to migrate the application to a more current version of Delphi.

This problem is connected with Delphi dbExpress, but not with our driver – any dbExpress driver will define this regular expression as parameters on parsing your query.
To solve this problem, remove comments from your query.
