please help me, i have been having sleepless nights on this code
Select max(convert(int,SubString(Employee_ID,PATINDEX('%[0-9]%',Employee_ID),Len(Employee_ID)))) from Employee
this code returns a value of 20, when i used sql server 2012
from a column(varchar()) that contains the following;
emp001
emp005
emp020
emp018
but now, in sql server compact 4.0 column(nvarchar()), the following errors are thrown;
Error Code: 80040E14
Message : Data conversion failed. [ OLE DB status value (if known) = 2 ]
Minor Err.: 26306
Source : SQL Server Compact ADO.NET Data Provider
Num. Par. : 2
i am using vb in vs 2012
please what am i not understanding?
thanks a lot

Reduce the select statement to its base components, something like 'select max(employee_id) from Employee). Then add in each clause one at a time until it breaks.
Understandable, 'select max(employee_id) from Employee' is not what you want, but it may help find the issue.

i found my way out by creating a new column, ID as a int data type,
i then used
Select Max(ID) from Employee
to get the maximum value.
finally i just send a string value of Emp"&ID to Employee_ID Column
Thanks for your Reply

Atomicity.
It looks a lot like a formatted field, with a string, and a number that gets padded (for displaying purposes). Each field should hold an atomic value; the example consists of two facts, and should have been split over two fields. That's assuming that "emp" is not a constant.

Which is half of what Eddy suggested, the ID is correct but storing the "Emp" & ID is wrong, this information has no value and is only required in the UI/Reports. It should be created in the output, not stored.
This argument goes out the window if you need to maintain backwards compatibility with a crappy design.

No it doesn't 
You can always keep such stuff in a view, sp or a query.
I'm accepting one argument only for keeping a crappy design, and that is: If it's not broken, don't fix it.

thanks to you all.
guess i will learn more about atomicity.
life became very much easier when i used
Select Max(Employee_ID) from Employee
then using substring to trim the output to taste.
thanks to you all, i really appreciate it

Hi. When I try to run the following code, I get the error I wrote in the subject.

drop procedure if exists example_cursor;
create procedure example_cursor() reads sql data

declare var_wage numeric(8,2);

declare cur1 cursor for
select employee_id, salary, department_id from employees;
-- set done to 1 if data wasn't found
declare continue handler for not found set done = 1;
-- open cursor
open cur1;
-- start loop
emp_loop:loop
-- get data from cursor
fetch cur1 into var_employee_id, var_wage, var_department_id;
if(done = 1) then
leave emp_loop;
end if;
end loop emp_loop;

close cur1;
end;

Have a look at this PL/SQL cursor example[^].

Thanks GuyThiebaut. I Solved the problem even with the warning: I just printed the content with concat.
delimiter
drop procedure if exists sp_exemplo_cursor;
create procedure sp_exemplo_cursor() reads sql data
begin
declare var_salario numeric(8,2);
declare var_empregado_id int;
declare var_departamento_id int;
declare flag_nao_encontrado int default 0;
declare csr cursor for
select employee_id, salary, department_id from employees;
declare continue handler for not found set flag_nao_encontrado = 1;
open csr;
exemplo_loop:loop
fetch csr into var_empregado_id, var_salario, var_departamento_id;
if flag_nao_encontrado = 1 then
leave exemplo_loop;
end if;
select concat(var_empregado_id, ' ', var_salario, ' ', var_departamento_id);
end loop exemplo_loop;
close csr;
end

SQL Server 2008R2.
Do all defaults need a constraint name? Why would you or would you not use a constraint name?
Example of a SSMS created table script:
ALTER TABLE [dbo].[MyTable] ADD CONSTRAINT [DF_MyTable_MyDateColumn] DEFAULT (getdate()) FOR [MyDateColumn]
GO
ALTER TABLE [dbo].[MyTable] ADD DEFAULT ((0)) FOR [MyBitColumn]
GO
Thanks

From what I read on table constraints[^]
It's to maintain backwards compatibility.

It's always a good idea to use constraint names. Makes it easy to disable/drop a constraint.

Hello,
I am executing the following script:
use[SomeDatabase]
DECLARE @TEST_XML TABLE (Column_XML XML)
DECLARE @VAR VARCHAR(MAX) = 'EXECUTE dbo.sp_GetData 3229';
INSERT @TEST_XML EXEC (@Var)
SELECT * FROM @TEST_XML
any clues as to why I am receiving this error message, "The FOR XML clause is not allowed in a INSERT statement"? How can I get around this?
I really just need to get this data into a temp table.

Because "dbo.sp_GetData" uses a FOR XML clause.

Remove the XML clause.

Than what's the use of using XML?

I have one column table with negative and positive values and want to display positive and negative values in different columns using SQL Query.
Column
-10000
-17000
16000
25000
output should be like
A B
-----------------
-10000 16000
-17000 25000
|
|
|
|
|
And how do you determine that 16000 and -10000 belong into the same column, but not 16000 and -25000? What's the rule behind that?
|

One of the problems you will have with creating a query to do this is that the column of numbers will most likely not have an equal number of positive and negative values. Even if it does, I don't know of a way to create a single query to create the output you illustrate. The best I could do in this situation is the following which will output the same number of rows as in the original table but simply put a NULL value in the column that does not apply:
SELECT
CASE
WHEN NumberField > 0 THEN NumberField
ELSE NULL
END AS PositiveNumbers,
CASE
WHEN NumberField < 0 THEN NumberField
ELSE NULL
END AS NegativeNumbers
FROM NumbersTable
Of course, you also have to decide what exactly to do with values of zero.
