EssBeginReport

Starts sending a report specification to the active database. This call must be followed by successive calls to EssSendString() to send the report specification, and finally by a call to EssEndReport(). The report data can either be output, or the report specification can just be verified and any errors returned. Also, the corresponding data blocks in the database can optionally be locked by this call (lock for update).

Syntax

ESS_FUNC_M EssBeginReport (hCtx, Output, Lock);
ParameterData TypeDescription

hCtx

ESS_HCTX_T

API context handle.

Output

ESS_BOOL_T

Controls output of data. If TRUE, data is output from the server, according to the specified report. If FALSE, no data is output.

Lock

ESS_BOOL_T

Controls block locking. If TRUE, all blocks which are accessed by the report specification are locked for update. If FALSE, no blocks are locked.

Notes

Return Value

None.

Access

This function requires the caller to have read privilege (ESS_PRIV_READ) to one or more members in the active database.

Example

ESS_FUNC_M
ESS_Report (ESS_HCTX_T   hCtx,
            ESS_HINST_T  hInst
           )
{
   ESS_FUNC_M       sts     = ESS_STS_NOERR;
   ESS_STR_T     rString = NULL;
   sts = EssBeginReport (hCtx,ESS_TRUE,ESS_FALSE);
   if (!sts)
      sts = EssSendString (hCtx, "<Desc Year !");
   if (!sts)
      sts = EssEndReport (hCtx);
   /**************
    * Get report *
    **************/
   
   if (!sts)
      sts = EssGetString (hCtx, &rString);
   while ((!sts) && (rString != NULL))
   {
          printf ("%s", rString);
          EssFree (hInst, rString);
          sts = EssGetString (hCtx, &rString);
   }
   printf ("\r\n"); 
   
   return(sts);
}
