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();
}

foreach (GridViewRow g1 in GridView1.Rows)
{
SqlCommand cmd = new SqlCommand("INSERT INTO Order VALUES(#buyersName, #deliveryAddress, #productID, #productName, #category, CONVERT(VARBINARY(MAX), #image), #price, #paymentMode, #holderName)", con);
cmd.Parameters.AddWithValue("#buyersName", Label2.Text);
cmd.Parameters.AddWithValue("#deliveryAddress", TextBox1.Text);
cmd.Parameters.AddWithValue("#productID", g1.Cells[0].Text);
cmd.Parameters.AddWithValue("#productName", g1.Cells[1].Text);
cmd.Parameters.AddWithValue("#category", g1.Cells[2].Text);
cmd.Parameters.AddWithValue("#image", g1.Cells[3].Text);
cmd.Parameters.AddWithValue("#price", g1.Cells[4].Text);
cmd.Parameters.AddWithValue("#paymentMode", checkRadioButton());
cmd.Parameters.AddWithValue("#holderName", TextBox2.Text);
int r = cmd.ExecuteNonQuery();
}
When I run this code, it is showing an error that there is a syntax error near "Order". checkRadioButton() is returning the label of the selected RadioButton.
you can't have expression like convert() within the VALUE ()
Change to use
INSERT INTO [Order] (column name, ...)
select #buyersName, convert() ,...
by the way you should explicitly specify the column name in the INSERT clause or in future when you add a column to the table, your query will break
also why are you using reserved name as table name ?
Contrary to the statement in the other answer, it should be possible to CONVERT within the VALUES-section.
But there are multiple flaws or things that could be improved:
ORDER is a reserved word in sql server, put it in square brackets: [Order]
Don't use AddWithValue otherwise sql server infers the datatype, which could be problematic. Use Add instead. See here for more information.
You can convert the value of g1.Cells[3].Text to a byte-array (byte[]) before setting the parameter value. For conversion to byte[] see here.
Specify the columns in your query, to not break it when table changes in future
Change your code like following (column-names and datatypes may vary):
SqlCommand cmd = new SqlCommand(#"INSERT INTO [Order] (buyersName, deliveryAddress, productID, productName, category, image, price, paymentMode, holderName)
VALUES(#buyersName, #deliveryAddress, #productID, #productName, #category, #image, #price, #paymentMode, #holderName)", con);
cmd.Parameters.Add("#buyersName", SqlDbType.VarChar).Value = Label2.Text;
cmd.Parameters.Add("#deliveryAddress", SqlDbType.VarChar).Value = TextBox1.Text;
cmd.Parameters.Add("#productID", SqlDbType.VarChar).Value = g1.Cells[0].Text;
cmd.Parameters.Add("#productName", SqlDbType.VarChar).Value = g1.Cells[1].Text;
cmd.Parameters.Add("#category", SqlDbType.VarChar).value = g1.Cells[2].Text;
cmd.Parameters.Add("#image", SqlDbType.VarBinary).Value = g1.Cells[3].Text; //convert g1.Cells[3].Text to a byte array
cmd.Parameters.Add("#price", SqlDbType.Money) = g1.Cells[4].Text;
cmd.Parameters.Add("#paymentMode", SqlDbType.VarChar).Value = checkRadioButton();
cmd.Parameters.Add("#holderName", SqlDbType.VarChar).Value = TextBox2.Text;
int r=cmd.ExecuteNonQuery();
Hi I'm trying to use the update query to update a column or even a whole row, however when I only update a certain column i get "no value given for one or more required parameters". how can i use the code for both updating column and row also?
here's my code:
protected void updateButtn_Click(object sender, EventArgs e)
{
using (var myConnection = GetConnection())
{
myConnection.Open();
// You should be using a parameterized query here
using (var cmd = new OleDbCommand("Update client set username = ?, [name] = ?, surname = ?, [email] = ?, [password] = ? where id = ?", myConnection))
{
cmd.Parameters.AddWithValue("username", txt_uname.Text);
cmd.Parameters.AddWithValue("[name]", txt_name.Text);
cmd.Parameters.AddWithValue("surname", txt_sname.Text);
cmd.Parameters.AddWithValue("[email]", txt_email.Text);
cmd.Parameters.AddWithValue("[password]", txt_password.Text);
cmd.Parameters.AddWithValue("[id]", txt_id.Text);
cmd.ExecuteNonQuery();
} myConnection.Close();
}
}
You forgot to add a parameter for [health issues], that is the missing column the error is yelling at you about.
protected void clientUpdate_Click(object sender, EventArgs e)
{
using (var myConnection = GetConnection())
{
myConnection.Open();
using (var cmd = new OleDbCommand("Update client set [name] = ?, surname = ?, [date of birth] = ?, [health issues] = ?, [yoga experience] = ?, [email] = ?, [phone number] = ?, [home address] = ?, [password] = ? where id = ?", myConnection))
{
cmd.Parameters.AddWithValue("[name]", txt_name.Text);
cmd.Parameters.AddWithValue("surname", txt_sname.Text);
cmd.Parameters.AddWithValue("[date of birth]", txt_dob.Text);
cmd.Parameters.AddWithValue("[health issues]", txt_HealthIssues.Text); \\ <---- This was missing.
cmd.Parameters.AddWithValue("[yoga experience]", txt_exp.Text);
cmd.Parameters.AddWithValue("[email]", txt_email.Text);
cmd.Parameters.AddWithValue("[phone number]", txt_phone.Text);
cmd.Parameters.AddWithValue("[home address]", txt_address.Text);
cmd.Parameters.AddWithValue("[password]", txt_password.Text);
cmd.Parameters.AddWithValue("id", txt_id.Text);
cmd.ExecuteNonQuery();
}
}
}
If you want to only update 1 column you need to write a new query that does not include the other parameters in the query. Traditionally people will use a ORM library like Entity Framework to make this easier to do. You will need to check and see if you can find a ORM library that is compatible with your OleDb connection objects.
Also, if you do not go with a ORM you may want to not use AddWithValue, it has to make assumptions about what datatypes your code is and you can sometimes get large performance problems due to indexes not being used correctly when it guesses wrong.
The problem is that if one of those text boxes is empty, you're supplying a null value as a parameter. That's why you are getting the no value given error.
You can solve this problem by doing:
cmd.Parameters.AddWithValue("[name]", string.IsNullOrEmpty(txt_name.Text) ?
(object)DBNull.Value : txt_name.Text);
This will set the column value to null if the textbox is empty.
You could do something like this if you want to only update fields that have been filled out:
string cmd = "update blah set ";
bool shouldUpdate = false;
if (!string.IsNullOrEmpty(name_textbox))
{
shouldUpdate = true;
cmd += "name = ?,"; don't add the comma for the last one
command.Parameters.AddWithValue("name",name_textbox.Text);
}
... do this for each of your text boxes
if (shouldUpdate)
{
cmd += "where id = ?";
command.Parameters.AddWithValue("id",id);
command.ExecuteNonQuery();
}
but that is kinda ugly and I would recommend making sure the textboxes are populated with the current data when you're loading the page.
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
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...
