This error :

Try this one
private DataTable dataTable = new DataTable();
string connString = #"query string here";
string query = "select table";
SqlConnection conn = new SqlConnection(connString);
SqlCommand cmd = new SqlCommand(query, conn);
conn.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dataTable);
conn.Close();
da.Dispose();
I think you are using DataSet in your code might be there would be a problem
so you first need to check where that DataSet contains datatable at 0 location
eg.
DataSet ds = new DataSet();
dtAdapter.Fill(ds);
if(ds != null && ds.Tables.Count > 0) {
//your logic
}

Can anybody help me? Why am I getting this error?
If I remove the 'P' from the prod_id which left only number, it can work but if I add alphabet, it says "Invalid column name".
I already added .ToString() to it, but why it still can't take varchar and only take int.

This is the database table
CREATE TABLE [dbo].[Product2]
(
[prod_id] VARCHAR(6) NOT NULL,
[prod_name] VARCHAR(50) NOT NULL,
[prod_price] FLOAT(53) NOT NULL,
[prod_desc] VARCHAR(120) NOT NULL,
[prod_img] NVARCHAR(MAX) NOT NULL,
[prod_cat] VARCHAR(6) NOT NULL,
[stock_count] INT NULL,
[weight] DECIMAL(9, 2) NULL,
[width] DECIMAL(9, 2) NULL,
[length] DECIMAL(9, 2) NULL,
[height] DECIMAL(9, 2) NULL,
[shipping_fee] DECIMAL(9, 2) NOT NULL,
[created_at] DATETIME NOT NULL,
[updated_at] DATETIME NULL,
[prod_status] NVARCHAR(MAX) NULL,
PRIMARY KEY CLUSTERED ([prod_id] ASC),
CONSTRAINT [FK_Product2_ToTable]
FOREIGN KEY ([prod_cat]) REFERENCES [dbo].[Category] ([cat_id])
);
The way you pass the query could lead to SQL Injection.
SqlDataAdapter da = new SqlDataAdapter("select * from Product2 where prod_id=" + Request.QueryString["Id"] , conn);
I expect the final query you want to achieve is
select * from Product2 where prod_id=`P100`
But after revise your code if you do concatenate with 'P' in your query, you will get:
select * from Product2 where prod_id=P100
In which this will return result:
Invalid column name 'P100'
String concatenation into query is dangerous that possible break your query.
You need to create a SqlCommand variable and pass it to the SqlDataAdapter.
And also use SqlParameter to pass the parameter value.
SqlCommand cmd = new SqlCommand("select * from Product2 where prod_id = #Prod_ID", con);
cmd.Parameters.Add("#Prod_ID", SqlDbType.Varchar, 6).Value = "P" + Request.QueryString["id"].ToString;
After create and initialize SqlCommand, then you pass it into SqlDataAdpater as below
SqlDataAdapter da = new SqlDataAdapter(cmd);
Additional recommendation:
Use using block for your SqlConnection, SqlCommand and SqlDataAdapter as these (implemented with IDisposable interface) will automatically dispose the resources once the process is ended or exception is triggered.
DataSet ds = new DataSet();
using (SqlConnection conn = new SqlConnection(Global.cs))
{
using (SqlCommand cmd = new SqlCommand("select * from Product2 where prod_id = #Prod_ID", con))
{
cmd.Parameters.Add("#Prod_ID", SqlDbType.Varchar, 6).Value = "P" + Request.QueryString["id"].ToString;
using (SqlDataAdapter da = new SqlDataAdapter(cmd))
{
da.Fill(ds);
}
}
}
Updated answer with credited to #Tim Schmelter's suggestion
For Using declarations in C#8.0, you are not required to add scope for the using block.
A using declaration is a variable declaration preceded by the using keyword. It tells the compiler that the variable being declared should be disposed at the end of the enclosing scope.
DataSet ds = new DataSet();
using SqlConnection conn = new SqlConnection(Global.cs);
using SqlCommand cmd = new SqlCommand("select * from Product2 where prod_id = #Prod_ID", con);
cmd.Parameters.Add("#Prod_ID", SqlDbType.Varchar, 6).Value = "P" + Request.QueryString["id"].ToString;
using SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
I'm building a website in ASP.NET and I'd like to show only current date data in a GridView.
This is my C# code.
public void GridBind()
{
SqlCommand cmd_std = new SqlCommand("SELECT * FROM StudentInfo WHERE GRNo = '" + GR_No + "' AND school_id = '" + a + "' ", dbcon);
SqlDataAdapter sda_std = new SqlDataAdapter(cmd_std);
DataSet ds_std = new DataSet();
sda_std.Fill(ds_std);
if (ddlSubject.SelectedItem.Text == "All")
{
SqlCommand cmd = new SqlCommand("select * from HomeWork where Date >= '" + txtdate.Text + "' AND school_id='" + a + "' AND Standard='" + ds_std.Tables[0].Rows[0]["CurrentStd"].ToString() + "'", dbcon);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
sda.Fill(ds);
gvhw.DataSource = ds;
gvhw.DataBind();
}
else
{
SqlCommand cmd = new SqlCommand("select * from HomeWork where Date >= '" + txtdate.Text + "' AND Subject = '"+ddlSubject.SelectedItem.Text+"' AND school_id='" + a + "' AND Standard='" + ds_std.Tables[0].Rows[0]["CurrentStd"].ToString() + "'", dbcon);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
sda.Fill(ds);
gvhw.DataSource = ds;
gvhw.DataBind();
}
}
I need to display the current date inserted data show in GridView by default, i.e., if we bind the Grid on the page load then all data show in which I need to the same process but only show the current date data.
The question is not clear so I made some assumptions:
Use below code which will load the current date's record (When the actual page load)
string TDate = string.Empty;
if(string.IsNullOrEmpty(txtdate.Text))
{
TDate = DateTime.Now.ToString("dd/MM/yyyy");
}
else
{
TDate = txtdate.Text;
}
SqlCommand cmd = new SqlCommand("select * from HomeWork where Date = '" + TDate + "' AND school_id='" + a + "' AND Standard='" + ds_std.Tables[0].Rows[0]["CurrentStd"].ToString() + "'", dbcon);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
sda.Fill(ds);
gvhw.DataSource = ds;
gvhw.DataBind();
EDIT:
string NewDate = DateTime.Now.ToString("dd/MM/yyyy");
public void GridBind()
{
dbcon.Open();
SqlCommand cmd = new SqlCommand("select Id,FORMAT(Date,'dd/MM/yyyy') AS Date,Subject,Disc from NoticeBoard where school_id='" + a + "' and FORMAT(Date,'dd/MM/yyyy')= '" + NewDate + "' , dbcon);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
sda.Fill(ds);
gvTeacher.DataSource = ds;
gvTeacher.DataBind();
dbcon.Close();
}
I dont quite understand what you asked. Could you provide some expected output please? But if you just wanna to show the current date :
DateTime tudey = DateTime.Now;
public void GridBind()
{
dbcon.Open();
SqlCommand cmd = new SqlCommand("select Id,FORMAT(Date,'yyyy/MM/dd')AS Date,Subject,Disc from NoticeBoard where school_id='" + a + "'", dbcon);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
sda.Fill(ds);
gvTeacher.DataSource = ds;

dbcon.Close();

Given the following code to export each table in the database:
string strSql = "SELECT * FROM " + tableName;
SqliteConnection sqlCon = new SqliteConnection("Data Source=" + dbPath);
using (SqliteCommand sqlComm = new SqliteCommand(strSql, sqlCon) { CommandType = CommandType.Text })
{
var da = new SqliteDataAdapter(sqlComm);
DataSet ds = new DataSet();
da.Fill(ds);
ds.Tables[0].WriteXml(Path.Combine(syncPath, tableName + "_4.xml"));
}
I'm trying to import the XML back into the database with the following:
SqliteConnection sqlCon = new SqliteConnection("Data Source=" + dataPath + "/Empty.db3");
sqlCon.Open();
DataSet ds = new DataSet();
ds.ReadXml(Path.Combine(syncPath, tableName + "_4.xml"));
DataTable dt = ds.Tables[0];
string keyField = dt.Columns[0].ColumnName;
dt.PrimaryKey = new DataColumn[] { dt.Columns[keyField] };
var adapterForTable1 = new SqliteDataAdapter("Select * from " + tableName, sqlCon);
adapterForTable1.AcceptChangesDuringFill = false;
var builderForTable1 = new SqliteCommandBuilder(adapterForTable1);
adapterForTable1.Update(ds, tableName);
sqlCon.Close();
But I get the error: Dynamic SQL generation is not supported with no base table. How do I fix this?
Abandoned the Update option and wrote this:
SqliteConnection sqlCon = new SqliteConnection("Data Source=" + dataPath + "/Empty.db3");
sqlCon.Open();

string sqlString = "INSERT into " + tableName + " (";
string valString = "";
var sqlParams = new string[dt.Rows[0].ItemArray.Count()];
int count = 0;
foreach(DataColumn dc in dt.Columns)
{
sqlString += dc.ColumnName + ", ";
valString += "#" + dc.ColumnName + ", ";
sqlParams[count] = "#" + dc.ColumnName;
count++;
}
valString = valString.Substring(0, valString.Length - 2);
sqlString = sqlString.Substring(0, sqlString.Length - 2) + ") VALUES (" + valString + ")";
sqlCmd.CommandText = sqlString;
