如何使用Laravel-5构建以下MySQL查询？

public class SharedFormula {

    private final int _columnWrappingMask;
    private final int _rowWrappingMask;

    public SharedFormula(SpreadsheetVersion ssVersion) {
        this._columnWrappingMask = ssVersion.getLastColumnIndex();
        this._rowWrappingMask = ssVersion.getLastRowIndex();
    }

    public Ptg[] convertSharedFormulas(Ptg[] ptgs, int formulaRow, int formulaColumn) {
        Ptg[] newPtgStack = new Ptg[ptgs.length];

        RefPtgBase areaNPtg = null;
        AreaPtgBase var9 = null;
        Object ptg = null;
        byte originalOperandClass = 0;
        for(int k = 0; k < ptgs.length; ++k) {
            ptg = ptgs[k];
            originalOperandClass = -1;
            if(!((Ptg)ptg).isBaseToken()) {
                originalOperandClass = ((Ptg)ptg).getPtgClass();
            }

            if(ptg instanceof RefPtgBase) {
                if(ptg instanceof Ref3DPxg) {
                    areaNPtg = (Ref3DPxg)ptg;
                    this.fixupRefRelativeRowAndColumn(areaNPtg, formulaRow, formulaColumn);
                    ptg = areaNPtg;
                }else if(ptg instanceof Ref3DPtg) {
                    areaNPtg = (Ref3DPtg)ptg;
                    this.fixupRefRelativeRowAndColumn(areaNPtg, formulaRow, formulaColumn);
                    ptg = areaNPtg;
                }else {
                    areaNPtg = (RefPtgBase)ptg;
                    ptg = new RefPtg(this.fixupRelativeRow(formulaRow, areaNPtg.getRow(), areaNPtg.isRowRelative()), this.fixupRelativeColumn(formulaColumn, areaNPtg.getColumn(), areaNPtg.isColRelative()), areaNPtg.isRowRelative(), areaNPtg.isColRelative());
                }
                ((Ptg)ptg).setClass(originalOperandClass);
            }else if(ptg instanceof AreaPtgBase) {
                if(ptg instanceof  Area3DPxg) {
                    var9 = (Area3DPxg)ptg;
                    this.fixupAreaRelativeRowAndColumn(var9, formulaRow, formulaColumn);
                    ptg = var9;
                }else if(ptg instanceof  Area3DPxg) {
                    var9 = (Area3DPtg)ptg;
                    this.fixupAreaRelativeRowAndColumn(var9, formulaRow, formulaColumn);
                    ptg = var9;
                }else {
                    var9 = (AreaPtgBase)ptg;
                    ptg = new AreaPtg(this.fixupRelativeRow(formulaRow, var9.getFirstRow(), var9.isFirstRowRelative()), this.fixupRelativeRow(formulaRow, var9.getLastRow(), var9.isLastRowRelative()), this.fixupRelativeColumn(formulaColumn, var9.getFirstColumn(), var9.isFirstColRelative()), this.fixupRelativeColumn(formulaColumn, var9.getLastColumn(), var9.isLastColRelative()), var9.isFirstRowRelative(), var9.isLastRowRelative(), var9.isFirstColRelative(), var9.isLastColRelative());
                }
                ((Ptg)ptg).setClass(originalOperandClass);
            }else if(ptg instanceof OperandPtg) {
                ptg = ((OperandPtg)ptg).copy();
            }

            newPtgStack[k] = (Ptg)ptg;
        }

        return newPtgStack;
    }

    protected void fixupRefRelativeRowAndColumn(RefPtgBase areaNPtg, int formulaRow, int formulaColumn){
        areaNPtg.setRow(this.fixupRelativeRow(formulaRow, areaNPtg.getRow(), areaNPtg.isRowRelative()));
        areaNPtg.setColumn(this.fixupRelativeColumn(formulaColumn, areaNPtg.getColumn(), areaNPtg.isColRelative()));
        areaNPtg.setRowRelative(areaNPtg.isRowRelative());
        areaNPtg.setColRelative(areaNPtg.isColRelative());
    }

    protected void fixupAreaRelativeRowAndColumn(AreaPtgBase var9, int formulaRow, int formulaColumn){
        var9.setFirstRow(this.fixupRelativeRow(formulaRow, var9.getFirstRow(), var9.isFirstRowRelative()));
        var9.setLastRow(this.fixupRelativeRow(formulaRow, var9.getLastRow(), var9.isLastRowRelative()));
        var9.setFirstColumn(this.fixupRelativeColumn(formulaColumn, var9.getFirstColumn(), var9.isFirstColRelative()));
        var9.setLastColumn(this.fixupRelativeColumn(formulaColumn, var9.getLastColumn(), var9.isLastColRelative()));
        var9.setFirstRowRelative(var9.isFirstRowRelative());
        var9.setLastRowRelative(var9.isLastRowRelative());
        var9.setFirstColRelative(var9.isFirstColRelative());
        var9.setLastColRelative(var9.isLastColRelative());
    }

    protected int fixupRelativeColumn(int currentcolumn, int column, boolean relative) {
        return relative?column + currentcolumn & this._columnWrappingMask:column;
    }

    protected int fixupRelativeRow(int currentrow, int row, boolean relative) {
        return relative?row + currentrow & this._rowWrappingMask:row;
    }

}

修改

建议的link并没有解决我的问题，但是我确实找到了解决方案，并将其发布在其他人面前。

Answer 1

$order  = $order->select('orders.*', 'oi.items');
$order->join(DB::raw('(select order_id, group_concat(item_name SEPARATOR ",") as items from orders_items group by order_id) as oi'), function($join)
{
    $join->on('oi.order_id', '=', 'orders.id');
});
$order->whereRaw('find_in_set ("'.$value.'", oi.items)');

$rows = $order->get();
