I need help, I am trying to write a query string that gets data according to a particular date picked in the dataAndTimePicker tool but I keep getting the same exception "Conversion failed when converting date and/or time from character string."
this is the code I tried
str = "select imId,imCustomer,imAmount,imDiscount,imTotal,imPaid,imPayType,imDate from invoiceMaster where imDate >= '" + startDate.Value.ToString("dd/MM/yyyy") + "' and imDate <= '" + endDate.Value.ToString("dd/MM/yyyy") + "'";
SqlDataAdapter da = new SqlDataAdapter(str, declerations.con);
DataTable dt = new DataTable();
da.Fill(dt);
dgvInvoice.DataSource = dt;
Always use parameters instead of putting a values directly into a sql string
str = "select imId,imCustomer,imAmount,imDiscount,imTotal,imPaid,imPayType,imDate from invoiceMaster where imDate >= #StartDate and imDate <= #EndDate";
SqlCommand cmd = new SqlCommand(str, declarations.con);
cmd.Parameters.AddWithValue("#StartDate", startDate.Value);
cmd.Parameters.AddWithValue("#EndDate", endDate.Value);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
dgvInvoice.DataSource = dt;
str = "select imId,imCustomer,imAmount,imDiscount,imTotal,imPaid,imPayType,imDate from invoiceMaster where imDate >= '" + Convert.ToDateTime(startDate.Value) + "' and imDate <= '" + Convert.ToDateTime(endDate.Value) + "'";
SqlDataAdapter da = new SqlDataAdapter(str, declerations.con);
DataTable dt = new DataTable();
da.Fill(dt);
dgvInvoice.DataSource = dt;

In my database, the column is stored as 'Here is jurong', I want to read out the database row if the column contains the word jurong.
I tried using like but it cant work
Here is the code, please help
cmd = new SqlCommand("Select * from Thread WHERE (Delete_Status='No') AND (Thread_Location = '" + searchTB.Text + "' OR Thread_Title = '" + searchTB.Text + "' OR Thread_Description LIKE '%' + #Thread_Description + '%') ORDER BY ThreadID DESC ", con);
cmd.Parameters.Add("#Thread_Description", SqlDbType.VarChar).Value = searchTB.Text;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
reptater.DataSource = ds;
reptater.DataBind();
Does that SQL statement return rows when you run it in the database? Also, I'd be careful of SQL injection attacks when passing values not through parameters.
Should your 'reptater' bind to a DataTable rather than a DataSet?
cmd = new SqlCommand("SELECT * FROM Thread WHERE (Delete_Status='No') AND (Thread_Location = #SearchTxt OR Thread_Title = #SearchTxt OR Thread_Description LIKE '%' + #SearchTxt + '%') ORDER BY ThreadID DESC ", con);
cmd.Parameters.Add("#SearchTxt", SqlDbType.VarChar);
cmd.Parameters["#SearchTxt"].Value = searchTB.Text;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
reptater.DataSource = ds; //ds.Tables[0]; ?
reptater.DataBind();
This is code that references a SQL Server database to retrieve to information to be put into a DataGridView.
I get an error:
SqlException [incorrect syntax]
Code:
private void DisplayData()
{
adapt = new SqlDataAdapter("SELECT geoCode, cancer2004" +
"FROM Regional_Intel$" +
"WHERE geoCode LIKE '" + txtDMA.Text + "'", con);
// cmd.Parameters.AddWithValue("#dma", txtDMA.Text);
dt = new DataTable();
adapt.Fill(dt);
dataGridView1.DataSource = dt;
}
How can I fix it?
Add spaces in your SQL string. Also, very bad idea to use string concatenation.
Add spaces like this:
{
adapt = new SqlDataAdapter("Select geoCode, cancer2004 " +
"FROM Regional_Intel$ " +
"where geoCode LIKE '" + txtDMA.Text + "'", con);
//cmd.Parameters.AddWithValue("#dma", txtDMA.Text);
dt = new DataTable();
adapt.Fill(dt);
dataGridView1.DataSource = dt;
}
Use parameters like this:
{
adapt = new SqlDataAdapter("Select geoCode, cancer2004 " +
"FROM Regional_Intel$ " +
"where geoCode LIKE #dma", con);
adapt.SelectCommand.Parameters.Add("#dma", SqlDbType.NVarChar).Value = txtDMA.Text;
dt = new DataTable();
adapt.Fill(dt);
dataGridView1.DataSource = dt;
}
Separate out your SQL string:
{
var query = #"
SELECT geoCode, cancer2004
FROM Regional_Intel$
WHERE geoCode LIKE #dma";
adapt = new SqlDataAdapter(query, con);
adapt.SelectCommand.Parameters.Add("#dma", SqlDbType.NVarChar).Value = txtDMA.Text;
dt = new DataTable();
adapt.Fill(dt);
dataGridView1.DataSource = dt;
}
i want to filter dropdownlist by first 3 charater on job code, this is my query
string result3 = Checked_By.ToString().Substring(0, 3);
SqlCommand cmd = new SqlCommand(" SELECT [Kode], [Nama]
FROM [Job] WHERE LEFT(Kode, = '" + result3 + "') ORDER BY
Nama ASC", con);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
con.Open();
sda.Fill(dt);
con.Close();
This is straightforward fix. First, fix SQL syntax error (SQL LEFT function takes 2 parameter, a string and a number. LEFT('abcdef', 3) returns abc), next rewrite using parameters. Something like this.
string result3 = Checked_By.ToString().Substring(0, 3);
SqlCommand cmd = new SqlCommand(" SELECT [Kode], [Nama] FROM [Job] WHERE LEFT(Kode, 3) = #result3 ORDER BY Nama", con); //ASC is OK but not required as it is default option
cmd.Parameters.Add("#result3", SqlDbType.Char, 3).Value = result3;
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
//con.Open(); //not necessary. SqlDataAdapter.Fill opens connection if it needs
sda.Fill(dt);
//con.Close(); //and closed if it wasn't open before .Fill
"SELECT [Kode], [Nama]
FROM [Job] WHERE SUBSTR(Kode,1,3) = '" + result3 + "' ORDER BY
Nama ASC"
I have one column in SQL table. which name is Intime. Its data type is nvarchar. It stores both date and time. But I want date and time separately.
I have tried this query:
select AttendanceDate,
SUBSTRING(convert(varchar,intime,113),1,11)[Intime],
SUBSTRING(convert(varchar,intime,113),13,19)[InTime],
InDeviceId,
OutTime,
OutTime,
OutDeviceId,
dbo.MinutesToDuration(duration) as Duration,
Status
from dbo.AttendanceLogs
where EmployeeId=2938
order by AttendanceDate desc
but if I pass same SQL command in grid view its not working.
public void Bind()
{
SqlCommand cmd = new SqlCommand("select AttendanceDate,SUBSTRING(convert(varchar,intime,113),1,11) as [InTime],SUBSTRING(convert(varchar,InTime,113),13,19) as [Intime],InDeviceId,OutTime,OutTime,OutDeviceId, dbo.MinutesToDuration(duration) as Duration,Status from dbo.AttendanceLogs where EmployeeId='" + empIdtxt.Text + "' and year(AttendanceDate)=" + ddlYear.SelectedItem + " and month(AttendanceDate)=" + ddlmnt.SelectedValue + " order by AttendanceDate desc", con);
SqlDataAdapter da = new SqlDataAdapter();
cmd.Connection = con;
da.SelectCommand = cmd;
DataTable dt = new DataTable();
da.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
GridView1.ControlStyle.Font.Size = 10;
}
Where possibly could be the problem?
replace your code with this
public void Bind()
{
SqlCommand cmd = new SqlCommand(#"select AttendanceDate,SUBSTRING(convert(varchar,intime,113),1,11) as [InTimeD],SUBSTRING(convert(varchar,InTime,113),13,19) as [IntimeT],
InDeviceId,OutTime,OutTime,OutDeviceId, dbo.MinutesToDuration(duration) as Duration,Status from dbo.AttendanceLogs
where EmployeeId='" + empIdtxt.Text + "' and year(AttendanceDate)=" + ddlYear.SelectedItem.Value +
" and month(AttendanceDate)=" + ddlmnt.SelectedValue + " order by AttendanceDate desc", con);
SqlDataAdapter da = new SqlDataAdapter(cmd,con);
DataTable dt = new DataTable();
da.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
GridView1.ControlStyle.Font.Size = 10;
}
this line not filter any year it return object of drop down list
year(AttendanceDate)=" + ddlYear.SelectedItem + "
I have two tables and I want to search into them by using a TextBox and this is my code but wrong hope to help me
string constring = "Data Source =.; initial Catalog = business; Integrated Security=SSPI;";
SqlConnection CN = new SqlConnection(constring);
DataTable dt = new DataTable();
if (txtID.Text.Trim() != "")
{
SqlDataAdapter sda = new SqlDataAdapter("select tab1.ID ,tab1.DATMOSTAND ,tab1.MONY ,tab2.BYAN ,tab2.MONY from MAL_ERTEBAT,tab2 where tab1.ID = tab2.EID = '" + txtID.Text + "'", CN);
sda.Fill(dt);
}
dataGridView1.DataSource = dt;
where tab1.ID = tab2.EID = '" + txtID.Text + "'" this is the error part the message is "in correct syntax near ="
Hope you are missing the alias name:
Replace the above SqlDataAdapter with:
SqlDataAdapter sda = new SqlDataAdapter("select tab1.ID ,tab1.DATMOSTAND ,tab1.MONY ,tab2.BYAN ,tab2.MONY from MAL_ERTEBAT tab1,tab2 where tab1.ID = tab2.EID = '" + txtID.Text + "'", CN);
