replace dc_crdno WITH REPLICATE("*",12) + RIGHT(ALLTRIM(dc_crdno),4) FOR NOT EMPTY(dc_crdno) && IN csrReportThe problem is that I see just 12 * for some rows, so I assume that there may be some unprintable characters in that column. How can I make sure to either show 12* + 4 last digits or show empty value?
