我正在尝试使用 PL/SQL 中的以下代码将字符串转换为日期：

BEGIN
   vfrom := TO_DATE ('20/08/2013', 'dd/mm/yyyy');
   vto := TO_DATE ('30/08/2013', 'dd/mm/yyyy');

   OPEN L_CURSOR FOR
      SELECT DSAT.ORGANIZATION_ID,
             APPS.DAW_INV_ORG_NAME (DSAT.ORGANIZATION_ID) ORGANIZATION_NAME,
             APPS.DAW_CAT_NAME (MC.SEGMENT4) PRODUCT,
             TRUNC (NVL (DSAT.SCH_END_DATE, DSAT.SCH_START_DATE))
                TRANSACTION_DATE,
             TO_CHAR (NVL (DSAT.SCH_END_DATE, DSAT.SCH_START_DATE),
                      'MM-YYYY')
                MONTH,
             DSAT.ITEM_SEGMENTS ITEM_CODE,
             DSAT.ITEM_DESCRIPTION,
             DSAT.CURRENT_FORECAST_QUANTITY PLAN_QTY
        FROM APPS.DAW_SCPDB_ASCP_TPP_V DSAT,
             APPS.MTL_ITEM_CATEGORIES MIC,
             APPS.MTL_CATEGORIES MC
       WHERE     NVL (SCH_END_DATE, SCH_START_DATE) BETWEEN '$(vfrom)'
                                                        AND '$(vto)'
             AND MIC.CATEGORY_SET_ID = 1100000061         --- PLANING CATEGORY
             AND MC.CATEGORY_ID = MIC.CATEGORY_ID
             AND DSAT.INVENTORY_ITEM_ID = MIC.INVENTORY_ITEM_ID
             AND DSAT.ORGANIZATION_ID = MIC.ORGANIZATION_ID
             AND DSAT.FORECAST_SET = '$(vForecastSetDPL2)'; --- Need to Update it on Monthly Basis;
END PorductPlanningForecast;

错误发生为

ORA-01858: 在第 29 行预期为数字的地方发现了一个非数字字符

其中包括打开游标进行查询。我已经检查了 NSL 参数并在 to_Date 函数中将日期设置为此处的格式，在互联网上进行了搜索，但我无法弄清楚。请帮忙。

在线WHERE NVL(SCH_END_DATE,SCH_START_DATE) BETWEEN '$(vfrom)' and '$(vto)'你有字符串'$（vfrom）'到日期的隐式转换。那是行不通的。

假设 vfrom 和 vto 被声明为日期，该行应该是这样的WHERE NVL(SCH_END_DATE,SCH_START_DATE) BETWEEN vfrom and vto。
