ORA-01036 非法的变量名/编号,(解决)
下边的代码就会造成 ORA-01036 非法的变量名/编号
- cmd.CommandText = "SELECT * FROM kk.kkyh WHERE id = @comboBox1 and password = @textBox1 ";
- cmd.Parameters.Add("@comboBox1", OracleType.VarChar).Value = comboBox1.Text;
- cmd.Parameters.Add("@textBox1", OracleType.VarChar).Value = textBox1.Text;
把SQL中的@改成:，把.Add中的@去掉，就正常了
- cmd.CommandText = "SELECT * FROM kk.kkyh WHERE id = :comboBox1 and password = :textBox1 ";
- cmd.Parameters.Add("comboBox1", OracleType.VarChar).Value = comboBox1.Text;
- cmd.Parameters.Add("textBox1", OracleType.VarChar).Value = textBox1.Text;

最近写程序，用EnterpriseLibrary往Oracle中插入数据，出现错误ORA-01036:非法的变量名/编号，代码如下：
DbConnection m_con = g_db.CreateConnection();
m_con.Open();
DbCommand m_com = g_db.GetSqlStringCommand("insert into USER_DEPARTMENT(DEPARTNAME,PARENTDEPID) values(@departname,@parentdepid)");
g_db.AddInParameter(m_com, "@departname", DbType.String, this.TextBox1.Text);
g_db.AddInParameter(m_com, "@parentdepid", DbType.String, this.TreeView1.SelectedNode.Value);
g_db.ExecuteNonQuery(m_com);
m_con.Close();
若换成
DbCommand m_com = g_db.GetSqlStringCommand("insert into USER_DEPARTMENT(DEPARTNAME,PARENTDEPID) values('" + this.TextBox1.Text + "','" + this.TreeView1.SelectedNode.Value + "')");
则没有问题，上网查也没找到解决办法，经过一番探索，终于找到原因了，Oracle中好象不支持@，把@换成:就可以了，代码如下：
DbConnection m_con = g_db.CreateConnection();
m_con.Open();
DbCommand m_com = g_db.GetSqlStringCommand("insert into USER_DEPARTMENT(DEPARTNAME,PARENTDEPID) values(:departname,:parentdepid)");
g_db.AddInParameter(m_com, ":departname", DbType.String, this.TextBox1.Text);
g_db.AddInParameter(m_com, ":parentdepid", DbType.String, this.TreeView1.SelectedNode.Value);
g_db.ExecuteNonQuery(m_com);
m_con.Close();
另外，Oracle中如果不用begin...end，SQL语句中不要有分号(;)。

oracle中测试能过
最近写程序时，往Oracle中插入数据，出现错误ORA-01036:非法的变量名/编号，代码如下：
DbConnection conn = GetCon();
conn.Open();
DbCommand cmd = conn.CreateCommand();
string sqlrt= "insert into T_User(Id,Name,Password,E_Mail) VALUES(@id,@name,@password,@email)";
cmd.CommandText = sqlrt;
cmd.Parameters.Add(new SqlParameter("@id", Convert.ToInt32(txtId.Text)));
cmd.Parameters.Add(new SqlParameter("@name", txtName.Text));
cmd.Parameters.Add(new SqlParameter("@password", txtPassword.Text));
cmd.Parameters.Add(new SqlParameter("@email", txtEmail.Text));
int num = cmd.ExecuteNonQuery();
if (num > 0)
{
Response.Write("插入成功");
DataLoad();
}
解决方案是：
DbConnection conn = GetCon();
conn.Open();
DbCommand cmd = conn.CreateCommand();
string sqlrt= "insert into T_User(Id,Name,Password,E_Mail) VALUES(：id,：name,：password,：email)";
cmd.Parameters.Add(new OracleParameter(":id", Convert.ToInt32(txtId.Text)));
cmd.Parameters.Add(new OracleParameter(":name", txtName.Text));
cmd.Parameters.Add(new OracleParameter(":password", txtPassword.Text));
cmd.Parameters.Add(new OracleParameter(":email", txtEmail.Text));
在Oracle数据库中，参数替换不能使用"@",要使用":",将程序中的@替换成就可以解决这个问题了
