Hi all,
declare @str1 varchar(500)
declare @str2 varchar(500)
declare @str3 varchar(500)
declare @str4 varchar(500)
select @str1=ud_id from cm_tb_002 where username='admin';
select @str3=role_id from cm_tb_012 where tb012_id=@str1;
select @str4=tb001_id from cm_tb_001 where menu_activ = 1 and child_lvl = 0 and [15]='1';
select tb001_id from cm_tb_001 where menu_prnt=@str4;
Here i want to pass @str3 to a this query
select @str4=tb001_id from cm_tb_001 where menu_activ = 1 and child_lvl = 0 and @str3='1';
but the @str3 column is an bigint column. ex. 15 i.e column name
In sql sever this value is storing as [15] as column name. Now i want to
pass this value to this query
select @str4=tb001_id from cm_tb_001 where menu_activ = 1 and child_lvl = 0 and @str3='1';
Please help me on this.

You would need to construct your SQL statement as a string and execute it using the EXEC statement.

Hai all
In my table i have some records with serial number
ex:
1
2
3
4
5.
if i delete 3 means 4 should be decremented as 3 and 5 should be decremented as 4.
Plse give me a logic to do this.
Thanks in advance.
With regrds

I don't give code to people, especially when they haven't demonstrated that they have tried to solve the problem themselves.
I'll give you a hint though - use an UPDATE query to decrement all serial no. values greater than the one being deleted. Your biog states that you are a professional software engineer, so you should be able to figure out how to implement this.

UPDATE IPMS_TBL.VDR_WO_LINE_ITEM SET serialnumber=serialnumber-1
WHERE WO_ID=@WOId AND WO_LINE_ITEM_ID>@WOLineItemId
@WOLineItemId=id which i deleted

I assume that you mean that you have an identity column that you want to reorder on a delete. You should know that this is a dangerous thing to attempt. For a start, suppose that you have 10,000,000 records in a table and you delete record number 3. That leaves 9,999,996 records being updated just to keep this in sync. More importantly, if you have this fields as a PK and there are foreign key relationships then you also need to reorder all of those foreign keys. Please rethink this strategy before you attempt to go any further.

If you really need the records to be sequentially numbered in the output of a query, and you're using SQL Server 2005, consider sorting the output using ORDER BY and using the RANK function to get the sequential numbering.

there is 2 table named table 1 and table 2 in the db
where both table have a comman coloumn named employee_code.
let table1 conatain emplyee_code-1,2,6,8,9
and table2 contain employye_coce-2,4,6,7,8
now i want a sql statement which will give me the out put as follows
i want to check(let say employee code1) wather a particular employee_code
present in table 1 and not present in table2 .if it run succesfully it should give massage emplyee code exists else
doesn't exists.
means if i select emp_code 1 then the message would be "emplyee code exists"
i select emp_code 2 then the message would be "emplyee code doesnt exists"

Use the EXISTS[^] operator to check for the existence of rows with a particular employee code in table 2.

I don't follow the table layout, but it looks like you need something like
select sum(count), letter from tbl group by letter
where letter is the column that gives you A/B/C and count is the column you want to combine. use count instead of sum if you're counting columns and not combining their values

Your child table violates one of the principles of 1st normal form. Values for each column-row intersection should be atomic. You should consider splitting these values out, otherwise it will be very difficult to query the data efficiently.

Yes, it certainly does.

Hi all,
I have a dataset which has 3 tables. They have relation by ds.Relations.Add(...)
Now I want a filteration like a master table i.e. ds.tables(0) should be filtered by one column like ds.tables(0).Select("Site_ID = 5")
(which will return datarow array now) and I want its children rows should be filtered appropriately.
Instead of table.Select(...) is there any other way?
Thank You

You could create a DataView-object for the DataTable via DataView dv = new DataView(ds.Tables[0]);. Then set the RowFilter with this line
dv.RowFilter = "Site_ID = 5";

Sounds like you need to use the execute command correctly.

you may declare and use dynamic sql like this;
CREATE PROCEDURE GetRecords ( @DynamicColumnName varchar(100) ) AS
DECLARE @dynamicsql varchar(255)
SELECT @dynamicsql = 'SELECT Column1, Column2, Column3 ' +
'FROM TableName ORDER BY ' + @DynamicColumnName
EXEC(@dynamicsql)
Hope this will help.
