Avoiding SQL Injection[^] isn't hard:
protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
const string connectionstr = @"...";
const string sqlstring = "insert into Authenticate (username, password) VALUES (@username, @password)";
using (var con = new System.Data.SqlClient.SqlConnection(connectionstr))
using (var objcommand = new System.Data.SqlClient.SqlCommand(sqlstring, con))
{
objcommand.Parameters.AddWithValue("@username", CreateUserWizard1.UserName);
objcommand.Parameters.AddWithValue("@password", CreateUserWizard1.Password);
con.Open();
objcommand.ExecuteNonQuery();
}
Response.Redirect("~/Login.aspx");
}
Once you've fixed that problem, you then need to reconsider how you're storing the passwords. Currently, you're storing them as plain text, which is a terrible idea. If anyone managed to gain access to your database, they would be able to see every password used on your site.
Instead, you should be storing a salted hash of the passwords:

I am receiving an Overflow error from an INSERT statement. I understand this is because a value that is assigned to a variable is larger than the data type, correct? The database was built in Access.
I pinned the values on screen while debugging and took a screen shot, which is linked herewhich is linked here.
I have double checked the data types and they all seem to match.What am I missing?
Thank you in advance.
Here is the code:
<pre lang="c#"> oleDbComQC.CommandText = "INSERT INTO RANKS ([ACCOUNTS], [EOB], [FPD], [F90P], [PDCHECK], [INCOME], [PD], [PD90P]) " +
"VALUES(@ACCTS, @EOB, @FPD, @F90P, @PDC, @INC, @PD, @PD90)";
oleDbComQC.Parameters.AddWithValue("@ACCTS", OleDbType.Integer);
oleDbComQC.Parameters.AddWithValue("@EOB", OleDbType.Decimal);
oleDbComQC.Parameters.AddWithValue("@FPD", OleDbType.Integer);
oleDbComQC.Parameters.AddWithValue("@F90P", OleDbType.Integer);
oleDbComQC.Parameters.AddWithValue("@PDC", OleDbType.Integer);
oleDbComQC.Parameters.AddWithValue("@INC", OleDbType.Decimal);
oleDbComQC.Parameters.AddWithValue("@PD", OleDbType.Integer);
oleDbComQC.Parameters.AddWithValue("@PD90", OleDbType.Integer);
oleDbComQC.Parameters["@ACCTS"].Value = iAccts;
oleDbComQC.Parameters["@EOB"].Value = decEOB;
oleDbComQC.Parameters["@FPD"].Value = iFPD;
oleDbComQC.Parameters["@F90P"].Value = i90PD;
oleDbComQC.Parameters["@PDC"].Value = iNumChks;
oleDbComQC.Parameters["@INC"].Value = decIncome;
oleDbComQC.Parameters["@PD"].Value = iPPD;
oleDbComQC.Parameters["@PD90"].Value = iP90PD;

Firstly, you have to download the Oracle Database Software. go to oracle.com and download the software.
I suggest to download 11g R2 windows version. It's more easier to install on windows than on Linux.

Using SQL Server 2008 r2
I am trying to design a table, which has 2 computed column based on the product of other columns including a computed column, which SQL Server doesn't like.
CREATE TABLE [dbo].[BaseRate2](
[ProductType] [varchar](100) NOT NULL,
[LinkToRate] [decimal](18, 0) NULL,
[CopyOfRates] [decimal](18, 0) NULL,
[BCdiscountLoading] [decimal](18, 0) NULL,
[OtherLoading] [decimal](18, 0) NULL,
[ClaimsLoading] [decimal](18, 0) NULL,
[NoClaimsDiscount3Yr] [decimal](18, 0) NULL,
[NoClaimsDiscount4Yr] [decimal](18, 0) NULL,
[NoClaimsDiscount5Yr] [decimal](18, 0) NULL,
[ConstructionLoading] [decimal](18, 0) NULL,
[DiscretionaryDiscount] [decimal](18, 0) NULL,
[MinPremiumLoading] [decimal](18, 0) NULL,
[SecurityDiscount] [decimal](18, 0) NULL,
[ProductLoading] AS ((((((([ClaimsLoading]*[NoClaimsDiscount3Yr])*[NoClaimsDiscount4Yr])*[NoClaimsDiscount5Yr])*[ConstructionLoading])*[DiscretionaryDiscount])*[MinPremiumLoading])*[SecurityDiscount])
) ON [PRIMARY]
Now when I try to add the second computed column when uses the first computed column (ProductLoading) this is where SQL throws an error as it should do.
RateUsed as ([CopyOfRates] * [BCdiscountLoading] * [OtherLoading] * [ProductLoading])
Is there some other technique that I could design this table without manually calculating these product columns (ProductLoadings and RateUsed).
Thanks
Simon

It blows, because you're using a value in your calculation that might not be available yet. Create the table, and a view - add the second computed field to the view.
Alternatively, you could use a normal (non-calculated) field, and update it's contents using a trigger.

Eddy,
Thanks for that suggestion (views) it worked, but I decided against the idea after following through on the documentation of the table / view as it made it more complex to maintain in this situation.
So sadly I adopted the manual calculations before entering into the table.
Thanks again

As Eddie suggested the Product loading may not exists.
This is not going to make you happy. You can replace [ProductLoading] in your second field with the ENTIRE formula from the first field.
ducks and runs I told you it would not make you happy!

I understood the why it isn't working and was trying to see if there was another way to do this computationally.
while I did consider the approach you suggested, I also have to write detailed documentation around this insurance rating API and was looking for a easy / elegant solution that would make documentation easy and clear.
With the documentation in mind I decided that it would be easier for me to explain the columns and how they are calculated manually.

Why two dots? Does not look correct.

this is ok in my frame work
and you use this query with one dot
my problem is in join but not in dots
thank you for reply

You forget to include the error, and a hint as to which DBMS you're using.
Assuming MS SQL, try:
UPDATE
F
SET
[ReferenceGuid] = M.[Guid]
FROM
[Common]..[com_Files] As F
INNER JOIN [PersonnelSystem]..Missions As M
ON F.ReferenceID = M.ID
WHERE
F.[ReferenceFlag] = 72
AND
F.[ReferenceGuid] Is Null
AND
F.[ReferenceSoftwareGuid] = '66944D9C-31F4-4594-9407-4E1F64C079D9'
;

i solved this problem with this code:
UPDATE mycompany.dbo.Files
SET [ReferenceGuid] = ( SELECT mission.[GUID]
FROM dbo.Mission mission
WHERE mission.ID = [ReferenceID]
)
WHERE [ReferenceSoftwareGuid] = '66944D9C-31F4-4594-9407-4E1F64C079D9'

Thanking you

Don't store dates as strings. Change the column to datetime (or datetime2(0) if you're using SQL 2008 or higher), and then query for BookDate >= @Today And BookDate < @Tomorrow.
