Description:        ECPG : Can't delete an item pointed by a cursor
Details:

The statement : EXEC SQL DELETE  FROM <table> WHERE CURRENT OF <cursor name>
(describe in SQL 99) isn't recognize by ecpg

Ecpg returns ERROR: syntax error at or near "CURRENT" for the following
program :


EXEC SQL DECLARE C3_NTF CURSOR FOR
    SELECT
        NUM_NOTIF,
        TYPE_NOTIF,
        NOTIFIE,
        ACTION,
        NB_NVX_MSG
    FROM
        DISPNTEL
    FOR UPDATE;

    EXEC  OPEN C3_NTF;

...

    for(;;)
    {
...

          EXEC SQL FETCH C3_NTF
        INTO :SAPnum_notif,
             :SAPtype_notif,
             :SAPnotifie:INDnotifie,
             :SAPaction:INDaction,
             :SAPnb_nvx_msg:INDnb_nvx_msg;

...
      EXEC SQL DELETE  FROM DISPNTEL WHERE CURRENT OF C3_NTF;

...

    }


The yacc grammar do not authorize the keywords CURRENT OF

PostgreSQL does not implement the entire SQL standard by any means.
Please refer to the documentation about what you can expect to work and
how.

This holds for the backend as well, doesn't it?

The feature is not implemented and thus it makes no sense to allow it in
ecpg. But there are some patches that implement
the feature on gborg afaik.
