ade_qrysetcond

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.

char* pszBgnCondGrouping = "";  // none
char* pszNotOperator = "";      // none
