percentile_cont(.50) within group (order by height) over() as pctcont_50_ht,
percentile_cont(.72) within group (order by height) over() as pctcont_72_ht,

我用Google搜索但找不到任何解决方案.
如何在主窗体中加载面板内的其他窗体.
我正在尝试类似的东西
private void frmInitialEntryBooks_Load(object sender, EventArgs e)
{
frmSujbect objForm = new frmSujbect();
pnl.Controls.Add(objForm);
objForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
objForm.Dock = DockStyle.Fill;
objForm.Show();
}
但它抛出异常Top-level control cannot be added to a control的行pnl.Controls.Add(objForm);
WITH DTL AS
(SELECT CMPI_CODE,
CMN_CDTY_MTRL,
CMI_WT_FACTOR,
CMI_CNTRCT_RATE,
'PL',
PRESENT_PRICE,
TRM_CODE,
ROUND(((NVL(PRESENT_PRICE,1)*CMI_WT_FACTOR) / CMI_CNTRCT_RATE),2) AS PL_FACTOR
FROM VW_CMD_MATERIAL WHERE TRM_CODE = 41)
INSERT iNTO IPA_PRCADJ_HDR(TRM_CODE,IPAPH_ADJ_FACTOR,IPAPH_AMT_CUR,IPAPH_REMARKS)
SELECT TRM_CODE,SUM(PL_FACTOR) AS PL_FACTOR,((SUM(PL_FACTOR)*10)) AS AMT_CUR,'asdf'
FROM DTL GROUP BY (TRM_CODE);
显示错误 ORA-00928: missing SELECT keyword
有什么区别:MySql中的=和=赋值运算符？
使用这两个地方哪个地方稳定？
它是相同的还是仅仅是另一种选择？
为什么这显示错误..
