Hi Gautham,
Just got the query working, thanks!
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER procedure [dbo].[sp_searchFromCat]
(
@SearchCategory varchar(100) = null,
@SearchField varchar (100) = null
)
as
begin
declare @SQL varchar(4000)
set @SQL = 'select BookTitle, Author, Status from LibBooks ' +
case when @SearchCategory is null then ''
else 'where ' + @SearchCategory + ' like ' + '''%' + isnull(@SearchField,'') + '%'''
end

I am running the following query:
select sum(total) as 'Total QA Hours For F.I Centralized Alert Int', task.name as 'Project' from trans
inner join task on task.name=trans.task where trans.project = '374'
and [date] >= '1/31/2007'
group by task.name
The following error is returned.
Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to bigint.
Trans.task = bigint
Task.Name = Varchar (250)
trans.Total = float
Prsumably I need to use cast?
I have not been able to figure this one out.
Any help would be greatly appreciated.
Regards,
Hulicat

Hi,
As a disclaimer, I'm new to DB programming and .NET in general. My questions regard using parameters. I am developing a local application, and placing the right types of quotes in SQL statements depending on the datatype being passed is cumbersome. So, after doing some reading I'm attempting to use parameters.
So, if I'm using parameters, does it suffice to specify the OleDbDataType to catch an attempt to pass an incorrect datatype into a database field.
I suppose I'm a little unsure as to how much type-checking I need to apply to user input when using parameters.
Thanks for your help.

Whenever I've used parameters, trying to execute SQL causes an error if I've provided the wrong data type. I typically use a generic Try Catch block around the code that executes the SQL to catch errors like that.
Example:
Try<br />
myDataAdapter.Fill(myDataTable)<br />
Catch ex As Exception<br />
MessageBox.Show("Error: " & ex.Message)<br />
End Try
Hope this helps.

Hi all,
I am building an employee search application depending on 6 criterias(emp name,emp grade,dept,hire date,qualification,work timings).I have 4 tables-Employee,Emp_Qualifications,Work_Details,dept which are as follows.
Employee
------------------------------------------------------------------------
empid(PK) | fname | lname | grade | Designation | Dept_id(foriegn key) |
------------------------------------------------------------------------
dept
-----------------------------
Dept_id (PK) |Dept_name(PK) |
-----------------------------
Emp_Qualifications
---------------------------------
empid (PK) |qualification(PK) |
---------------------------------
123 | J2ME |
----------------------------------
123 | SAP |
----------------------------------
100 | Java |
----------------------------------
Work_Details
---------------------------------------------------------------
empid(PK) | Clear_Date(Date time)(PK) | document_name(PK) |
---------------------------------------------------------------
123 | 12/01/2007 | Balance sheet |
----------------------------------------------------------------
123 | 12/01/2007 | data sheet |
---------------------------------------------------------------
i want to select empid,fname,lname,designation,dept_name,(Collection of all expertise seperated by comma) for that empid from all tables where empid,name,dept,grade,qualification,work timings are provided by user.
Thanks in advance!!!

I'm assuming that you are using SQL-Server. You will need to use a database function to get the list of qualifactions:
CREATE FUNCTION dbo.ConcatQualifications(@EmpId INT) RETURNS VARCHAR(200)
AS BEGIN
DECLARE @Expertise VARCHAR(200), @Qualification VARCHAR(20)
DECLARE c1 CURSOR LOCAL FAST_FORWARD FOR
SELECT Qualification FROM Emp_Qualifications
WHERE EmpId = @EmpId
ORDER BY Qualification
OPEN c1
WHILE (@@FETCH_STATUS = 0) BEGIN
FETCH c1 INTO @Qualification
IF (@@FETCH_STATUS = 0) BEGIN
SET @Expertise = IsNull(@Expertise + ', ', '') + @Qualification
END
END
CLOSE c1
RETURN @Expertise
ENDThe basic query will look something like:
SELECT Employee.empid, Employee.fname, Employee.lname, Employee.designation,
Department.dept_name, dbo.ConcatQualifications(Employee.empid) Expertise
FROM Employee
INNER JOIN Department
ON Department.deptid = Employee.deptid
WHERE ####Your criteria goes here####
ORDER BY Employee.empid You can then insert any criteria that is relevent (e.g. "Employee.lname LIKE 'Smith%').
Once you have this working, you need to do a search on this forum for "SQL Injection" because the above criteria will fail (potentially dangerously) if the employee's name of "O'Leary".
Hope this helps.

Hi,
I set up SQL Express 2005 on WinServer 2003 and my program works fine locally with following connection string: (as suggested in www.connectionstrings.com)
Provider=SQLNCLI;Server=myServerName\MYSQLEXPRESS;Database=myDataBase;Uid=myUsername; Pwd=myPassword
Now, I want to run the program from a client connected to the server. I tried the following string:
Provider=SQLNCLI;Server=myServerName\MYSQLEXPRESS,1433;Database=myDataBase;Uid=myUsername; Pwd=myPassword
and it failed to connect with the following error message:
Code = 800a0e7a<br />
Code meaning = Unknown error 0x800A0E7A<br />
Source = ADODB.Connection<br />
Description = Provider cannot be found. It may not be properly installed.
I have the following enabled:
- remote connection "using both tcp/ip and named pipes" (from Surface Area Configuration)
- shared memory (from SQL Server Configuration Manager)
- SQL Server Browser service
On side note: (I don't know if these matter)
- SQL Server 2000 (full version) is installed
- the server is a domain controller (I am not sure, since I didn't set it up)
- there is no firewall
Is it possible that 1433 is not the right port? How to get/check the right port?
Can anyone help me here? Thanks in advance.

Sounds like you need to install SQL 2005 Network Client on the client box.
|
|
|
|
|
I'm not sure if your "Server=..." setting is valid.
This article may help with connection strings: Using Connection String Keywords with SQL Native Client[^]
Maybe "Address=..." is the one you want?
To configure TCP or check the configured port I believe you can use SQL server Management Studio.
Right-click the server, choose SQL Server Configuration Manager and go to the network
configuration/ protocols section.
|
|
|
|
|
I finally found and fixed the problem. It was my original hunch, that 1433 is not the right LISTENING port (although the setting of SQL Express still points to 1433). To check the port, run cmd.exe and look at the result of "netstat -ano".
Hopefully someone find this useful and don't need to spend days figuring this out.

Hi,
Here`s my problem.I have 2 tables Employee and Department as follows
Employee
----------------------------------------------------------------
empid | fname | Lname | Grade | Designation | Dept_id |
----------------------------------------------------------------
Department
---------------------
Dept_id |Dept_name|
---------------------
I want to select empid,fname,lname,grade,designation,Dept_name
I know this is very simple but i am weak in joins.Pls suggest a query such that i can select the values.
|
|
|
|
|
Select empid, fname, LName, Grade, Desination, Dept_name from Employee JOIN department on Department.Dept_id = Employee.Dept_id
(you cqn use LEFT JOIN to get all employees, even those have Dept_Id=null.)
Rédha.
|
|
|
|
|
|
select empid,fname,lname,grade,designation,Dept_name from employee e join department d
on e.dept_id=d.dept_id

Hi,
I merge a dataset into another dataset in my C# application.
While doing the dataset.Merge(myParamDataSet), the event 'position change' is raised from the 'bindingsource'.
Is there a way to stop all bindingsource events before the merge & after the merge?
Best regards,
Jens
