i have a little confusion...
DECLARE @name varchar(30)
SET @name = NULL
SELECT ISNULL(CONVERT(DATE,@name),'')
Result: 1900-01-01
But..
DECLARE @name varchar(30)
SET @name = NULL
SELECT ISNULL(@name,'')
Does NULL inherit a datatype after convert?
In the below scenario we are inserting some time related fields in Temp table.But its data type is varchar. Once data loading is finished in the temp table (Data is loading by source team SQOOP and they are unable to load if the source datatype is having Date or datetime) we have to alter the column datatypes. somehow, some character data in inserted in date columns (look at into 3rd insert statement). while altering the table it is failing. Can we do any alternative for this (Means if any varchar data that is non convertible to date can we make as null)
INSERT INTO ##TEMP_TEST
SELECT '2014-09-30','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM'
UNION SELECT '2014-09-29','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM'
UNION SELECT '2014-09-28','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM'

Hello,
What is the Datatype for NULL ? How SQL Server stores NULL ? I have seen many discussions on this. Some say's that NULL will be considered as character type, then what about NULL value comes in a number column ?
Another article say's NULL is untyped. It don't have any type. Which one is correct ? Will there any difference for NULL in SQL Server and Oracle ?
Any help would be appreaciated
Hi all,
There are several columns called enabled with a char datatype in my database. One enabled column per table. These columns either have a value of T or F (true or false), depending on whether they're enabled or not. I want to change these columns to a bit datatype and insert the relevant value of true or false...
I guess the best way to do this is to add a new column to a table with a bit datatype, and based on the value in the current enabled column, insert TRUE or FALSE.
Anyone ideas on the best way to accomplish this?
Thanks.
Hi all,
I am using a varchar datatype for PIN number to handle zero at start. Now i want to do mathematical calculation to encrypt the PIN so i need to convert that varchar datatype to int so that zero should not be discarted after conversion. i.e. 0123 and 123 must not be treated as same PIN.
Please kindly give me a way out. I am using RSA encryption.
Thanks in anticipation.

View 1 Replies View RelatedI have a number of bit datatypes ( Boat types: Cruiser, Sportfisher, Megayacht, Sailboat) that I would like to place in a text box and do away with the individual selections.

View 1 Replies View RelatedHi,
I read the topic from JROdden and this case is similiar but...
I got several varchar fields with
values like
1.2
1.3
... these I can covert with
select CONVERT(dec(5,2), fieldname) as fieldname
In fact I also solved undefined- and NULL-values with.
CONVERT(decimal(12, 2), CASE WHEN GESCHKOSTMAX IS NULL OR
GESCHKOSTMAX < '0' THEN '0' ELSE GESCHKOSTMAX END) as GESCHKOSTMAX,
But now there are values like
1,4 and these ones neither CONVERT nor CAST will handle.
I tried the
SELECT DISTINCT KMPAUSCHALE
FROM extr_INTFIRMA
WHERE (isnumeric(KMPAUSCHALE) = 1)
and get
0,40
0.25
0.30 and so on...
The error is:
[Microsoft][ODBC SQL Driver][SQL Server]Error converting datatype varchar to decimal. (or float or numeric (whatever I tried))
I think the easiest way would be to insist on higher data quality but
I also would like to solve this interesting challenge.
Thanks for any hints

I'm using a table to hold data that I can pass back to the original form page and re-populate the fields that were not validated correctly. The stored procedure either inserts or updates the record in the temp table I've created.
So, currently, as I'm testing, I'm just passing empty values to all the parameters and the @state parameter is failing and throwing the error.
I've double checked that the table has the state column set to integer datatype
The column is set as follows:
Name datatype length Allow Nulls
----------------------------------------------
State int 4 checked
I have tried setting the default value for every column to Null in the table and then also not using a default value. Either way, I still recieve the same error?
Not sure what else to look at?
It seems the problem might be that instead of a null value being passed to the parameter that it is actually empty. Can passing an empty value to a column of datatype integer cause this problem? If so, is there a way to correct it?
Thanks for any help.
1) it is in the same filegroup as the rest of the table?
2) it is stored in a filegroup separately from the rest of the table (I think this is allowed)?
how do i insert null value to a column with 'int' datatype. This columnn is primary key. Please help.

Hi I have a varchar(8000) and currently XML files are stored in varchar(8000).Some times when i am doing manuplactions in my varchar column i am getting with special characters error. so now i want to keep my column varchar(MAX) and when i am doing calculations i will convert my varchar datatype to xml datatype. By doing this i hope there wont be any special character problems.
When i am doing calculations with the wellformed xml i am getting error for both convert and cast methods as below
I am trying to do convert(xml,MyVarcharColumn)
Implicit conversion from data type xml to nvarchar is not allowed. Use the CONVERT function to run this query.
Also i tried with casting and getting same problme. is there any way to convert
please suggest me
Thanks

Hi,
on a migration from access 97 to SQL Server 7.0 columns in access like 'hyperlink' are converted to datatype 'text' on the SQL Server 7.0. Now I miss the function in the access application I had before with fields like 'hyperlink'. Now I can't start e.g. a word document with a click and I have to type in the hyperlink manualy.
Does anyone had the same problem an possibly have a resolve?

How do we convert int datatype to "time format" like hh:mm:ss
ex: 123092 ( this 12 + 30 min + 92 sec)

111747 ( 11 + 17 min + 47 sec)
I'm trying to convert a column in my source table of datatype varchar(6) to a column of datatype int in my destination. I tried using the Derived Column/Data Conversion transformations but none of them worked. So, I tried using the following C# (credits to the original poster) and getting an error during compilation.
Note: "MyCol" is the Input Column I've specified in the Script Component and "CleanCol" is the Output column I've specified as datatype [DT_I4].
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
int colOut = 0;
if (!Int32.TryParse(Row.MyCol, out colOut))
{
Row.CleanCol_IsNull = true;
} else {
Row.CleanCol = colOut;
}
}
The best overloaded method match for 'int.TryParse(string, out int)' has some invalid arguments
The other expression I've tried was:
ISNULL(MyCol) ? (dt_i4)"" : (dt_i4)MyCol
From the above code, you might have understood that the source field has some blank records as well in the MyCol field.
What is the best possible way to do the conversion from a String to Int or fixing the error from the above.
Ok I have upgraded my works database from a poorly designed Access database to a SQL database. The previous system allowed NULL values and duplicates to be inserted into a field that should NOT ALLOW NULL Values or duplicates. Therefore, this issue has now been moved across to my new system as I cannot set these constraints on the field that has multiple NULL values.
My solution would be to use a sequential operator, so whatever = NULL would be changed to a sequential number that us as administrators would know was a bogus number starting at something like = 999999900 counting up from that. There are only 250 records that would require updating.
To make things more interesting this field is not a integer type, its a Nvarchar type as its a Hardware ID. Both numerical and characters are require.
Hi,
is there a way to inherit from ExecutePackageTask? I try to build my own control flow component, mainly doing the same as the named task, with some special logging and configuration.
Application.LoadPackage(); Package.Execute(); Execute the Packages, but IMHO dont have the ability to jump into the package and show up the flow in the BI-Studio DebugMode.
So I will give it a try to inherit from ExecutePackageTask and customize the behavior.
Thanks
