ade_qrygetcond

Query Functions

Gets a condition of the current query.

struct resbuf*

ade_qrygetcond(

ade_id condition_id);

Returns a query condition or NULL.

You must release the resbuf.

See ade_qrydefine for information about query conditions.

The following sample shows the use of ade_qrygetcond() only. A resbuf is created, the resbuf is filled based on the return of ade_qrygetcond(). Then it releases the resbuf, as required.

struct resbuf* pNewQueryConditionRb = NULL;
pNewQueryConditionRb = ade_qrygetcond(queryId);
acutRelRb(pQueryConditionRb);

The following sample shows the use of ade_qrygetcond() in conjunction with ade_qrydefine().

char* pszJoinOperator = "";     // none
char* pszBgnCondGrouping = "";  // none
char* pszNotOperator = "";      // none
char* pszCondType = "Property";
char* pszEndCondGrouping = "";  // none
struct resbuf* pQueryConditionRb = acutBuildList(
                                                    RTLB,
                                                        RTSTR, "feature",
                                                        RTSTR, "=",
                                                        RTSTR, "Pond",
                                                    RTLE,
                                                    0 );
ade_id queryId = ade_qrydefine(
                                    pszJoinOperator,
                                    pszBgnCondGrouping,
                                    pszNotOperator,
                                    pszCondType,
                                    pQueryConditionRb,
                                    pszEndCondGrouping);
if (queryId != ADE_NULLID) {
    acutPrintf(
        "\nA query has been defined with the following condition:\n\n");
}
else {
    acutPrintf(
        "\nThere are no defined queries.");
}
acutRelRb(pQueryConditionRb);
struct resbuf* pNewQueryConditionRb = ade_qrygetcond(queryId);
if(NULL != pNewQueryConditionRb) {
    struct resbuf* rb = pNewQueryConditionRb;
    while(NULL != rb) {
        if(rb->restype == RTSTR){
            acutPrintf(
                    "\"%s\" "
                    , rb->resval.rstring);
        }
        rb = rb->rbnext;
    }
}
else{
    acutPrintf(
        "\nNo information could be retrieved.");
}
acutRelRb(pNewQueryConditionRb);

After running the code, take notice of how the command line display matches the ade_qrydefine() parameter list.
