下邊的代碼就會(huì)造成 ORA-01036 非法的變量名/編號(hào)
- 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;

最近寫程序，用EnterpriseLibrary往Oracle中插入數(shù)據(jù)，出現(xiàn)錯(cuò)誤ORA-01036:非法的變量名/編號(hào)，代碼如下：
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();
若換成
DbCommand m_com = g_db.GetSqlStringCommand("insert into USER_DEPARTMENT(DEPARTNAME,PARENTDEPID) values('" + this.TextBox1.Text + "','" + this.TreeView1.SelectedNode.Value + "')");
則沒有問題，上網(wǎng)查也沒找到解決辦法，經(jīng)過一番探索，終于找到原因了，Oracle中好象不支持@，把@換成:就可以了，代碼如下：
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語(yǔ)句中不要有分號(hào)(;)。

最近寫程序時(shí)，往Oracle中插入數(shù)據(jù)，出現(xiàn)錯(cuò)誤ORA-01036:非法的變量名/編號(hào)，代碼如下： 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();
} 解決方案是： 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數(shù)據(jù)庫(kù)中，參數(shù)替換不能使用"@",要使用":",將程序中的@替換成就可以解決這個(gè)問題了
