例如：

<TEXBC_EX_NUM001 check="noempty" datatype="float" name="明细-订单金额" sql="TEX_Batch_Count/TEXBC_EX_NUM001|SELECT ISNULL(SUM(BILLC_CURR_AMOUNT),0) AS AMOUNT FROM VEX_CSH_KHCPDD WHERE USER_ID='$current()/TEXBC_PROJECT_T$' AND IYEAR='$current()/TEXBC_EX_NUM006$' AND IMONTH >='$TEXBC_EX_NUM007$' AND '$TEXBC_EX_NUM009$'>=IMONTH">0</TEXBC_EX_NUM001>

如果不是 TBILL_CONTENT 节字段，需要写全路径和分割符，如：

TEX_Batch_Count/TEXBC_EX_NUM001|
