前几天我就遇到了这个需求，我之前实习写过.noodjs，处理过一些这样的需求，不过那时候我很菜，都是SQL大法整出来的，
但是SqlServer就没有MySQL那么好用了，sql写复杂了对效率和稳定性会有不小的影响
我现在的需求就是我先截一张图，给各位看看，需求是什么
四张表，一个表未基本表，另外三张表分别根据不同的时间段去统计
所以在代码上我是，四哥个简单查询sql，然后四个datatable将他们放进去，通过四张表的主外键串起来，最后塞到datagridview中
第一步先将期初，本期的时间写出来，以便后面进行where，期初：为上月的最后一天，本期未本月，本月我用的datatimepiker控件，
付代码：
string yue = dateTimePicker1.Text.Trim();//拿到datatimepiker控件的值
string tian = Convert.ToDateTime(yue).AddMonths(0).AddDays(-1).ToString("yyyy-MM-dd");//得到上个月最后一天
几个sql，这里的我将所有的sql塞到datatable中
//即时库存
string ss = "select materialsId as 物料编码,materialsName as 物料名称,specification as 规格型号 ,unit as 单位 from MaterialStock";
da = new SqlDataAdapter(ss, SQL);
dt = new DataTable();
da.Fill(dt);
//期初入库
string str = "select materialsId as 物料编码,materialsName as 物料名称,specification as 规格型号 ,unit as 单位 ,sum(unitNumber) as 数量 ,sum(purchasingPrice) as 单价,sum(stockAmount) as 金额 from PutStockDetial where date like '%" + tian + "%' group by materialsId,materialsName,specification,unit";
da1 = new SqlDataAdapter(str, SQL);
dt1 = new DataTable();
da1.Fill(dt1);
//期初出库
string str1 = "select materialsId as 物料编码,materialsName as 物料名称,specification as 规格型号 ,unit as 单位 ,sum(unitNumber) as 数量 ,sum(purchasingPrice) as 单价,sum(stockAmount) as 金额 from OutStockDetial where date like '%" + tian + "%' group by materialsId,materialsName,specification,unit";
da2 = new SqlDataAdapter(str1, SQL);
dt2 = new DataTable();
da2.Fill(dt2);
//本期收入
string str2 = "select materialsId as 物料编码,materialsName as 物料名称,specification as 规格型号 ,unit as 单位 ,sum(unitNumber) as 数量 ,sum(purchasingPrice) as 单价,sum(stockAmount) as 金额 from PutStockDetial where date like '%" + yue + "%' group by materialsId,materialsName,specification,unit";
da3 = new SqlDataAdapter(str2, SQL);
dt3 = new DataTable();
da3.Fill(dt3);
//本期发出
string str3 = "select materialsId as 物料编码,materialsName as 物料名称,specification as 规格型号 ,unit as 单位 ,sum(unitNumber) as 数量 ,sum(purchasingPrice) as 单价,sum(stockAmount) as 金额 from OutStockDetial where date like '%" + yue + "%' group by materialsId,materialsName,specification,unit";
da4 = new SqlDataAdapter(str3, SQL);
dt4 = new DataTable();
da4.Fill(dt4);
然后将在定义一个datatable，将以上所有datatable中的所需的列全部塞到新的datatable中，未定义的新的datatable为dtt
//添加列名称
DataTable dtt = new DataTable();
dtt.Columns.Add("时间", typeof(string));
dtt.Columns.Add("物料编码", typeof(string));
dtt.Columns.Add("物料名称", typeof(string));
dtt.Columns.Add("规格型号", typeof(string));
dtt.Columns.Add("单位", typeof(string));
dtt.Columns.Add("期初收入数量", typeof(int));
dtt.Columns.Add("期初收入单价", typeof(decimal));
dtt.Columns.Add("期初收入金额", typeof(decimal));
dtt.Columns.Add("期初发出数量", typeof(int));
dtt.Columns.Add("期初发出单价", typeof(decimal));
dtt.Columns.Add("期初发出金额", typeof(decimal));
dtt.Columns.Add("期初结存数量", typeof(int));
dtt.Columns.Add("期初结存单价", typeof(decimal));
dtt.Columns.Add("期初结存金额", typeof(decimal));
dtt.Columns.Add("本期收入数量", typeof(int));
dtt.Columns.Add("本期收入单价", typeof(decimal));
dtt.Columns.Add("本期收入金额", typeof(decimal));
dtt.Columns.Add("本期发出数量", typeof(int));
dtt.Columns.Add("本期发出单价", typeof(decimal));
dtt.Columns.Add("本期发出金额", typeof(decimal));
dtt.Columns.Add("期末结存数量", typeof(int));
dtt.Columns.Add("期末结存单价", typeof(decimal));
dtt.Columns.Add("期末结存金额", typeof(decimal));
然后循环不同的datatable，将需要的值取出来一次的塞到dtt里面的列中
//库存表
for (int i = 0; i < dt.Rows.Count; i++)
{
dr = dtt.NewRow();
string wlbm = dt.Rows[i]["物料编码"].ToString();
string wlmc = dt.Rows[i]["物料名称"].ToString();
string gg = dt.Rows[i]["规格型号"].ToString();
string dw = dt.Rows[i]["单位"].ToString();
dr["时间"] = yue;
dr["物料编码"] = wlbm;
dr["物料名称"] = wlmc;
dr["规格型号"] = gg;
dr["单位"] = dw;
//期初入
for (int j = 0; j < dt1.Rows.Count; j++)
{
id1 = dt1.Rows[j]["物料编码"].ToString();
if (wlbm == id1)
{
slR = Convert.ToInt32(dt1.Rows[j]["数量"]);
djR = Convert.ToDecimal(dt1.Rows[j]["单价"]);
jeR = Convert.ToDecimal(dt1.Rows[j]["金额"]);
dr["期初收入数量"] = slR;
dr["期初收入单价"] = djR;
dr["期初收入金额"] = jeR;
}
}
//期初出
for (int k = 0; k < dt2.Rows.Count; k++)
{
id2 = dt2.Rows[k]["物料编码"].ToString();
if (wlbm == id2)
{
slC = Convert.ToInt32(dt2.Rows[k]["数量"]);
djC = Convert.ToDecimal(dt2.Rows[k]["单价"]);
jeC = Convert.ToDecimal(dt2.Rows[k]["金额"]);
dr["期初发出数量"] = slC;
dr["期初发出单价"] = djC;
dr["期初发出金额"] = jeC;
}
}
//本期收入
if (dt3.Rows.Count > 0)
{
for (int ii = 0; ii < dt3.Rows.Count; ii++)
{
if (wlbm == dt3.Rows[ii]["物料编码"].ToString())
{
sl1 = Convert.ToInt32(dt3.Rows[ii]["数量"]);
dj1 = Convert.ToDecimal(dt3.Rows[ii]["单价"]);
je1 = Convert.ToDecimal(dt3.Rows[ii]["金额"]);
dr["本期收入数量"] = sl1;
dr["本期收入单价"] = dj1;
dr["本期收入金额"] = je1;
}
/*else
{
dr["本期收入数量"] = 0;
dr["本期收入单价"] = 0;
dr["本期收入金额"] = 0;
}*/
}
}
//本期发出
for (int jj = 0; jj < dt4.Rows.Count; jj++)
{
if (wlbm == dt4.Rows[jj]["物料编码"].ToString())
{
sl2 = Convert.ToInt32(dt4.Rows[jj]["数量"]);
dj2 = Convert.ToDecimal(dt4.Rows[jj]["单价"]);
je2 = Convert.ToDecimal(dt4.Rows[jj]["金额"]);
dr["本期发出数量"] = sl2;
dr["本期发出单价"] = dj2;
dr["本期发出金额"] = je2;
}
/*else
{
dr["本期发出数量"] = 0;
dr["本期发出单价"] = 0;
dr["本期发出金额"] = 0;
}*/
}
//添加行内容
dtt.Rows.Add(dr);
接下来的部分是数据处理，不同表向减的数据，然后放入到dtt中，但是相减会出现空指针异常，所以这里面就拿到dtt中的部分数据，进行判空，然后将null值赋值为0
if (dtt.Rows.Count > 0)
{
for (int x = 0; x < dtt.Rows.Count; x++)
{
if (dtt.Rows[x]["期初收入数量"] == DBNull.Value)
dtt.Rows[x]["期初收入数量"] = 0;
int a = Convert.ToInt32(dtt.Rows[x]["期初收入数量"]);
if (dtt.Rows[x]["期初收入单价"] == DBNull.Value)
dtt.Rows[x]["期初收入单价"] = 0;
decimal b = Convert.ToDecimal(dtt.Rows[x]["期初收入单价"]);
if (dtt.Rows[x]["期初收入金额"] == DBNull.Value)
dtt.Rows[x]["期初收入金额"] = 0;
decimal c = Convert.ToDecimal(dtt.Rows[x]["期初收入金额"]);
if (dtt.Rows[x]["期初发出数量"] == DBNull.Value)
dtt.Rows[x]["期初发出数量"] = 0;
int a1 = Convert.ToInt32(dtt.Rows[x]["期初发出数量"]);
if (dtt.Rows[x]["期初发出单价"] == DBNull.Value)
dtt.Rows[x]["期初发出单价"] = 0;
decimal b1 = Convert.ToDecimal(dtt.Rows[x]["期初发出单价"]);
if (dtt.Rows[x]["期初发出金额"] == DBNull.Value)
dtt.Rows[x]["期初发出金额"] = 0;
decimal c1 = Convert.ToDecimal(dtt.Rows[x]["期初发出金额"]);
if (dtt.Rows[x]["本期收入数量"] == DBNull.Value)
dtt.Rows[x]["本期收入数量"] = 0;
decimal a2 = Convert.ToDecimal(dtt.Rows[x]["本期收入数量"]);
if (dtt.Rows[x]["本期收入单价"] == DBNull.Value)
dtt.Rows[x]["本期收入单价"] = 0;
decimal b2 = Convert.ToDecimal(dtt.Rows[x]["本期收入单价"]);
if (dtt.Rows[x]["本期收入金额"] == DBNull.Value)
dtt.Rows[x]["本期收入金额"] = 0;
decimal c2 = Convert.ToDecimal(dtt.Rows[x]["本期收入金额"]);
if (dtt.Rows[x]["本期发出数量"] == DBNull.Value)
dtt.Rows[x]["本期发出数量"] = 0;
decimal a3 = Convert.ToDecimal(dtt.Rows[x]["本期发出数量"]);
if (dtt.Rows[x]["本期发出单价"] == DBNull.Value)
dtt.Rows[x]["本期发出单价"] = 0;
decimal b3 = Convert.ToDecimal(dtt.Rows[x]["本期发出单价"]);
if (dtt.Rows[x]["本期发出金额"] == DBNull.Value)
dtt.Rows[x]["本期发出金额"] = 0;
decimal c3 = Convert.ToDecimal(dtt.Rows[x]["本期发出金额"]);
dtt.Rows[x]["期初结存数量"] = a - a1;
dtt.Rows[x]["期初结存单价"] = b - b1;
dtt.Rows[x]["期初结存金额"] = c - c1;
dtt.Rows[x]["期末结存数量"] = (a2 - a3) + (a - a1);
dtt.Rows[x]["期末结存单价"] = (b2 - b3) + (b - b1);
dtt.Rows[x]["期末结存金额"] = (c2 - c3) + (c - c1);
}
}
接下来将最终处理好的dtt放入datagridview中
dataGridView1.DataSource = dtt;
后面需要对得到的数据进行汇总统计处理，有些不需要显示的列名称就隐藏起来
if (dataGridView1.Rows.Count > 0)
{
dataGridView1.Columns["期初收入数量"].Visible = false;
dataGridView1.Columns["期初收入单价"].Visible = false;
dataGridView1.Columns["期初收入金额"].Visible = false;
