[英]ORA-00911: invalid character?
我收到以下错误:
ORA-00911:XDocument doc = Document.Load(crtCommand.ExecuteScalar()。ToString())处的字符无效; *
使用此代码:
using (OracleConnection conn1 = new OracleConnection(oradb1))
{
conn1.Open();
using (OracleCommand crtCommand
= new OracleCommand("SELECT dbms_metadata.get_sxml('VIEW','VIEW_TBL_A') FROM dual;", conn1))
{
XDocument doc = XDocument.Load(crtCommand.ExecuteScalar().ToString());
XNamespace ns = "http://xmlns.oracle.com/ku";
if (doc.Descendants(ns + "COL_LIST_ITEM").Any(c => c.Attributes().Any()))
MessageBox.Show("COL_LIST has value");
else
MessageBox.Show("COL_LIST has no value");
}
}
摆脱尾随的分号。
using (OracleCommand crtCommand = new OracleCommand(
"SELECT dbms_metadata.get_sxml('VIEW','VIEW_TBL_A') FROM dual", conn1))
当传递单个语句以立即执行时,Oracle不喜欢语句分隔符。
