Please help me, I don't know what can be wrong with the following code:
OdbcConnection conn = new OdbcConnection(connString);
String query = "INSERT INTO customer (custId, custName, custPass, "+
"custEmail, custAddress, custAge) VALUES (" +
"#ID, #Name, #Pass, #Email, #Address, #Age)";
OdbcCommand exe = new OdbcCommand(query, conn);
exe.Parameters.Add("#ID", OdbcType.UniqueIdentifier).Value = id;
exe.Parameters.Add("#Name", OdbcType.VarChar).Value = name;
exe.Parameters.Add("#Pass", OdbcType.VarChar).Value = pass;
exe.Parameters.Add("#Email", OdbcType.VarChar).Value = email;
exe.Parameters.Add("#Address", OdbcType.VarChar).Value = address;
exe.Parameters.Add("#Age", OdbcType.Int).Value = age;
conn.Open();
exe.ExecuteNonQuery(); // ERROR [07002] [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 6.
This code throws me Too few parameters. error when I am trying to execute query. The database is fine, it works fine when I hardcode values into a query, instead of using parameters.
Thank you.
From MSDN:
When CommandType is set to Text, the .NET Framework Data Provider for ODBC does not support passing named parameters to an SQL statement or to a stored procedure called by an OdbcCommand. In either of these cases, use the question mark (?) placeholder. For example:
SELECT * FROM Customers WHERE CustomerID = ?
Rewrite your query to
OdbcConnection conn = new OdbcConnection(connString);
String query = "INSERT INTO customer (custId, custName, custPass, "+
"custEmail, custAddress, custAge) VALUES (" +
"?, ?, ?, ?, ?, ?)";
Order of Parameter counts!
EDIT: Parameter can be added this way:
OdbcCommand exe = new OdbcCommand(query, conn);
exe.Parameters.Add("ID", OdbcType.UniqueIdentifier).Value = id;
exe.Parameters.Add("Name", OdbcType.VarChar).Value = name;
exe.Parameters.Add("Pass", OdbcType.VarChar).Value = pass;
exe.Parameters.Add("Email", OdbcType.VarChar).Value = email;
exe.Parameters.Add("Address", OdbcType.VarChar).Value = address;
exe.Parameters.Add("Age", OdbcType.Int).Value = age;
One of your columns in your query does not exist.
Please check your column names.
Typically you'll see this when you misspell a column name in your SQL statement. Are you sure of those column names (custId, custName, etc.)?
try changing pass to passw maybe it is getting mixed up with asp identifier...

I want to insert rows every interval in c#. I'm getting this error:
[42000][Microsoft][ODBC SQL Server Driver][SQL Server] incorrect
syntax near ';'.
Here is the code:
cmdString = $"INSERT INTO {n}" + "VALUES (?, ?);";
using (OdbcCommand comm = new OdbcCommand())
{
comm.Connection = connection;
comm.CommandText = cmdString;
comm.Parameters.Add("value", System.Data.Odbc.OdbcType.Int).Value = value;
comm.Parameters.Add("time", System.Data.Odbc.OdbcType.DateTime).Value = System.DateTime.Now;
comm.ExecuteNonQuery();
rows += 1;
}
please help
EDIT
Now everything seems to be ok, but I can't see the rows appear in the tables in sql server :/ Can you please help me with that too? here is my connectionstring:
connetionString = "Driver={Sql Server}; Server=baxu\\sqlexpress; Database = baza1;" + $"UID ={ username };PWD={ password };";
Your command string is false, missing space before values. So, instead of
cmdString = $"INSERT INTO {n}" + "VALUES (?, ?);";
do this:
cmdString = $"INSERT INTO {n} VALUES (?, ?);";
or, if you insist in concatenation:
cmdString = $"INSERT INTO {n}" + " VALUES (?, ?);";
//notice the space here ----------^
also, check if n contains existing table name
Depend on n value, you will have different cmdString. Probably, n contains table name without space, so, resulting sting will have table name and value glued together.
Check value of cmdString in debugger (or output it to log).
How can I get this query to work? keep getting this error:
"syntax error in INSERT INTO statement"
I am confused as it used to work on another program, but I got all scrambled up with this one.
string item = listView1.Items[listView1.FocusedItem.Index].Text;
MessageBox.Show(item); //test Value
string thisDay1 = DateTime.Now.ToString();
ad.InsertCommand = new OleDbCommand("INSERT INTO Scrap-Rework Master Data (Is_today, S_Line, Status, T_Number, Test_Cp, think_a, Rew_Hos, QAffect, Comments)
values (?, ?, ?, ?, ?, ?, ?, ?, ?)", con);
ad.InsertCommand.Parameters.AddWithValue("#S_Line", OleDbType.VarChar).Value = textBox1.Text;
ad.InsertCommand.Parameters.AddWithValue("#Status", OleDbType.VarChar).Value = domainUpDown1.Text;
ad.InsertCommand.Parameters.AddWithValue("#T_Number", OleDbType.VarChar).Value = textBox2.Text;
ad.InsertCommand.Parameters.AddWithValue("#Test_Cp", OleDbType.VarChar).Value = item;
ad.InsertCommand.Parameters.AddWithValue("#think_a", OleDbType.VarChar).Value = domainUpDown2.Text;
ad.InsertCommand.Parameters.AddWithValue("#Rew_Hos", OleDbType.Numeric).Value = Double.Parse(textBox4.Text);
ad.InsertCommand.Parameters.AddWithValue("#QAffect", OleDbType.Numeric).Value = int.Parse(textBox3.Text);
ad.InsertCommand.Parameters.AddWithValue("#Comments", OleDbType.VarChar).Value = textBox5.Text;
ad.InsertCommand.Parameters.AddWithValue("#Is_today", OleDbType.DBTime).Value = thisDay1;
Listview has 2 columns:
ListViewItem listitem = new ListViewItem(dr["Test_Cp"].ToString());
listitem.SubItems.Add(dr["Description"].ToString());
fields on access database and type:
S_Line -Short Text;
Status -Short Text;
T_Number -Short Text;
Test_Cp -Short Text;
think_a -Short Text;
Rew_Hos -Number;
QAffect -Number;
Comments -Long Text;
Is_today -Date/Time;
Thank you so much in advance.
First you must use brackets [] always for the name that contains spaces in query like [Scrap-Rework Master Data].
2- Declare OleDbCommand parameter.
3- Put name of Parameters in query with respect order.
4- Format DateTime field.
5- add cmd.ExecuteNonQuery(); for insert data.
string item = listView1.Items[listView1.FocusedItem.Index].Text;
MessageBox.Show(item); //test Value
OleDbCommand cmd = new OleDbCommand("INSERT INTO [Scrap-Rework Master Data] (S_Line, Status, T_Number, Test_Cp, think_a, Rew_Hos, QAffect, Comments, Is_today)" +
"values(#S_Line, #Status, #T_Number, #Test_Cp, #think_a, #Rew_Hos, #QAffect, #Comments, #Is_today)", con);
cmd.Parameters.AddWithValue("#S_Line", textBox1.Text);
cmd.Parameters.AddWithValue("#Status", domainUpDown1.Text);
cmd.Parameters.AddWithValue("#T_Number", textBox2.Text);
cmd.Parameters.AddWithValue("#Test_Cp", item) ;
cmd.Parameters.AddWithValue("#think_a", domainUpDown2.Text);
cmd.Parameters.AddWithValue("#Rew_Hos", Double.Parse(textBox4.Text)) ;
cmd.Parameters.AddWithValue("#QAffect", int.Parse(textBox3.Text)) ;
cmd.Parameters.AddWithValue("#Comments", textBox5.Text) ;
cmd.Parameters.AddWithValue("#Is_today", DateTime.Now.ToString("#yyyy/MM/dd#"));
cmd.ExecuteNonQuery();
You're using OleDB, so you can't use named parameters:
System.Data.OleDb
Uses positional parameter markers indicated by a question mark (?).
which means (from same page)
As a result, the order in which Parameter objects are added to the Parameters collection must directly correspond to the position of the ? placeholder for the parameter.
The problem is your order is wrong: the first value in your INSERT is Is_Today, but that's the last value you add to the parameter array. Hence all the value types are wrong. Try moving
ad.InsertCommand.Parameters.AddWithValue("#Is_today", OleDbType.DBTime).Value = thisDay1;
to the head of your parameter add list.
Also I agree with abrown's comment: you'll likely need to bracket the table name [Scrap-Rework Master Data] since it has spaces and a dash in it.
Try to use stored procedure in DB:
using (var command1 = new SqlCommand("InsertData", conn)
{
CommandType = CommandType.StoredProcedure
})
{
command1.Parameters.Add("#a1", SqlDbType.Text).Value = A1;
command1.Parameters.Add("#a2", SqlDbType.Text).Value = A2;
command1.Parameters.Add("#a3", SqlDbType.Text).Value = A3;
command1.Parameters.Add("#a4", SqlDbType.Text).Value = A4;
command1.ExecuteNonQuery();
}
I am facing a strange problem, When i try to run the below code to update a record in access db.
string updateQuery = "UPDATE Employee SET Employee_name = #name, Employee_desig = #designation, Employee_salary = #salary, Employee_phone = #phone, Employee_mobile = #mobile, Employee_email = #email, Employee_status = #status WHERE (((Employee_id)=#empId));";
dbCmd.CommandText = updateQuery;
dbCmd.Parameters.AddWithValue("#designation", designation);
dbCmd.Parameters.AddWithValue("#email", email);
dbCmd.Parameters.AddWithValue("#mobile", mobile);
dbCmd.Parameters.AddWithValue("#name", name);
dbCmd.Parameters.AddWithValue("#phone", phone);
dbCmd.Parameters.AddWithValue("#salary", salary);
dbCmd.Parameters.AddWithValue("#status", status);
dbCmd.Parameters.AddWithValue("#empId", employeeId);
dbCmd.ExecuteNonQuery();
ExecuteNonQuery() return 1. But when i check in db, inputs are updated in different columns.
input values are
designation="Manager"
email="e"
mobile="2"
name="n"
phone="1"
salary=10.0
status="Active"
employeeId=3
any help will be appreciated.
In the context of ACE OLEDB the parameter names are ignored and the parameters must be defined in the same order that they appear in the SQL statement.
I am using this code to update "SOME" columns in a table in my database. But everytime I try to do so an error is given.
No value given for one or more required parameters.
con.Open();
SlipDA = new OleDbDataAdapter();
string sqlUpdate = "Update tbl_Slip SET RaiseBasic=#RaiseBasic, OtherDed=#OtherDed, Arrears=#Arrears, Notes=#Notes WHERE SlipNo=#SlipNo";
SlipDA.UpdateCommand = new OleDbCommand(sqlUpdate, con);
SlipDA.UpdateCommand.Parameters.AddWithValue("#RaiseBasic", Convert.ToInt32(dRow[4].ToString()));
SlipDA.UpdateCommand.Parameters.AddWithValue("#OtherDed", Convert.ToInt32(dRow[5].ToString()));
SlipDA.UpdateCommand.Parameters.AddWithValue("#Arrears", Convert.ToInt32(dRow[7].ToString()));
SlipDA.UpdateCommand.Parameters.AddWithValue("#Notes", dRow[8].ToString());
SlipDA.UpdateCommand.Parameters.AddWithValue("#SlipNo", dRow[0].ToString());
SlipDA.UpdateCommand.ExecuteNonQuery();
con.Close();
The table contains 9 columns but I only want to update a few.
This Could be the problem :
The OLE DB .NET Provider does not support named parameters for passing
parameters to an SQL statement or a stored procedure called by an
OleDbCommand when CommandType is set to Text. In this case, the
question mark (?) placeholder must be used. For example: SELECT * FROM
Customers WHERE CustomerID = ?
source : this
so basically your query should be like this :
string sqlUpdate = "Update tbl_Slip SET RaiseBasic= ?, OtherDed= ?, Arrears= ?, Notes= ? WHERE SlipNo= ?";
try this
string sqlUpdate = "Update tbl_Slip SET RaiseBasic=#RaiseBasic, OtherDed=#OtherDed, Arrears=#Arrears, Notes=#Notes WHERE SlipNo=#SlipNo";
OleDbCommand UpdateCommand = new OleDbCommand(sqlUpdate, con);
UpdateCommand.Parameters.AddWithValue("#RaiseBasic", Convert.ToInt32(dRow[4].ToString()));
UpdateCommand.Parameters.AddWithValue("#OtherDed", Convert.ToInt32(dRow[5].ToString()));
UpdateCommand.Parameters.AddWithValue("#Arrears", Convert.ToInt32(dRow[7].ToString()));
UpdateCommand.Parameters.AddWithValue("#Notes", dRow[8].ToString());
UpdateCommand.Parameters.AddWithValue("#SlipNo", dRow[0].ToString());
con.Open();
UpdateCommand.ExecuteNonQuery();
con.Close();
OleDbConnection vcon = new OleDbConnection(#"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\SummerJob\DataBase.accdb");
string cmdtxt = "UPDATE Students SET S_Name = ?, S_Surname = ?, S_E-Mail = ? WHERE ID = ?";
OleDbCommand cmd = new OleDbCommand(cmdtxt, vcon);
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("S_Name", EditName.Text);
cmd.Parameters.AddWithValue("S_Surname", editSurname.Text);
cmd.Parameters.AddWithValue("S_E-Mail", editMail.Text);
vcon.Open();
cmd.ExecuteNonQuery();
vcon.Close();
//i use this code but it says syntax error in update statement
Where is the last parameter ???
ID=?
Not sure, but I will bet that without that parameter your query doesn't look right to the parser.
You need to pass ID? via SqlParameter like this cmd.Parameters.AddWithValue("ID", Id.Text);
Also make sure that the parameters are added in the same order they occur
