serialNoこれは、文字列ではなく何らかの数値であると仮定して、それを行う1つの方法です。
- 上に示したように、SQL クエリ結果のデータセットは で並べ替える
serialNo必要があります。
Report Group次のグループ式で を作成します: $V{GroupCount} == new BigDecimal(0) ? $F{serialNo}:$F{serialNo}.subtract($V{GroupCount}). serialNoこれにより、シーケンスにギャップがあるたびに新しいグループが作成されます。- 現在のグループ内
GroupCountの連続する値の数をカウントする変数を作成します。この変数は、次に期待される値serialNoを追跡するために使用されます。serialNo
StartRange連続する値の特定の範囲の開始値を保持する変数を作成しserialNoます。値は、新しいグループの開始時にリセットされ、次の値を持つ必要があります: $V{GroupCount}.intValue() == 1 ? $F{ID}:$V{StartRange}.- フィールドの
Evaluation Time値を に設定します。次の値を入れます。serialNoReportGroup$V{StartRange}+" - " + $F{serialNo}
- バンドの を次のように
Print When Expression変更します。Detailnew Boolean($V{GroupCount}.intValue() == 1)
