Oracle ODAC x64位问题，此操作不支持Append_values提示批处理错误模式

Question

我正在使用x64位ODAC从.net webservice连接到oracle 11g。 代码失败：＆＃34;错误：ora-38910：此操作不支持批处理模式＆＃34;使用append_values提示执行查询时。 x64位oracle客户端版本2.112.1.0是否支持此提示。相同版本的x86位oracle客户端工作正常。

OracleParameter[] aryParams = null;
System.Text.StringBuilder SQlcols = new System.Text.StringBuilder();
System.Text.StringBuilder SQLvalues = new System.Text.StringBuilder();
System.Text.StringBuilder SQL = new System.Text.StringBuilder();
Int32 pNum = 1;

if (colFields.Count > 0)
{
    foreach (tblField fld in colFields.Values)
   {
       if (!fld.IsStaticValue)
        {
            fld.CleanUp();
            if (fld.ValueArray == null)
            {
                return false; // If no values were added to the arrays, exit function
            }

            if (aryParams == null)
            {
                aryParams = new OracleParameter[1];
            }
