Replaces a query condition.
int
ade_qrysetcond(
ade_id condition_id,
struct resbuf* condition);
Returns RTNORM or an error code.
| condition_id | Query condition ID to replace. |
| condition | New query condition (a list). See ade_qrydefine. |
This function affects the current query.
You cannot alter grouping with this function. Any grouping you specify is ignored. To group or ungroup, use ade_qrygroup or ade_qryungroup.
The following sample defines a query using ade_qrydefine(). A resbuf is created which contains the replacement query condition. This resbuf and the query condition id returned by ade_qrydefine() are used as parameters to ade_qrysetcond(). The value returned by ade_qrysetcond() is checked against RTNORM and an appropriate message is displayed. The resbuf is then released as required.
