Example DBquery($numftxt FROM OPEN OBJECT) Result: "2" DBquery($const.#P,$x,$y from open point /noq) Result: #P 3437515.669844 5381368.123192 DBquery($numSym,$sym.1.$pos.$x,$sym.1.$pos.$y,$sym.1.$angle FROM OPEN OBJECT /NOQUOTE ) Result: 2 3463732.61 5585791.64 278.987 DBquery($num FROM SYMBOL) Result: "232" "237" "230" s_sort(DBquery($num FROM SYMBOL)) Result: "230" "232" "237" DBquery($name from open object /noq) Result: VS_20kV_Kabel DBquery(GID from open object /noq) Result: 1-1-1-1-10 DBquery(KRK,GID,RNR from object) Result: "500" "1-1-1-1-2" "1" "450" "1-1-1-4-15" "4" "400" "1-1-1-2-2" "2" DBquery($pointer from open object /noq) Result: PTR_25d33f4 DBquery($name from object QTX $name LIKE VS_* /noq) Result: VS_20kV_Kabel VS_20kV_Freileitung VS_20kV_Muffe_A VS_20kV_Mast_E VS_NSP_Kabel VS_NSP_Muffe_HA_Abzw VS_NSP_Muffe_E VS_NSP_Muffe_HA_Abzw VS_NSP_Muffe_HA_Abzw DBquery($pointer from point QTX $link EQ 3 QTX $num GT 1 /noq) Result: PTR_25eb15c PTR_25fbd84 PTR_25fbcac PTR_25fbc1c DBquery($pointer from all point) Result: "" (The return value is too long and is not displayed in the command window)
Remarks Under Analysis | Generate Attribute Query, you'll find a dialog that helps you create a DBquery query. If the return value is too long, the result won't be displayed in the command window, but it can still be assigned to a variable. (See the last example) Siehe auch List of pseudo attributes
