Is there anyway to take the whole condition part of WHERE clause as a parameter of a stored procedure ?
The result I want to gain is something that would be achieved by executing this stored procedure.Although this is wrong , I want to achieve the result.Is there anyway get this result ?
CREATE PROCEDURE sp_GetList
@condition varchar(50)
AS
SELECT * FROM Table_X WHERE @condition

Yor problem is not very clear what exactly you want? Do you want to fetch the recordset on basis of some condition, if so then that is where you can use "where" clause. Something like this:
select * from emp where empid = @EID
where @EID is the parameter to that stored procedure.

No No no.
I want the condition to be like a variable for example this:
condition -> (column1='x' AND column2='y' OR column3='z')
I want the stored procedure to take the aformentioned condition as a varchar and use it in WHERE clause. To take the whole condition part of WHERE CLAUSE as parameter.
Is there any way

ya sure there is a way what you can do is create your where condition in front end, send that complete condition as string to the stored procedure. In stored procedure you take one variable(where the sql statement will be stored) and append the where string and then use sp_executesql to execute the complete string.

Thank you very much for your help.Could you please show me some basic code ?
|
|

Here a sample code which you can use in your stored procedure taken from sqlserver help:
DECLARE @IntVariable INT<br />
DECLARE @SQLString NVARCHAR(500)<br />
DECLARE @ParmDefinition NVARCHAR(500)<br />
<br />
<br />
SET @SQLString =<br />
N'SELECT * FROM pubs.dbo.employee WHERE job_lvl = @level'<br />
SET @ParmDefinition = N'@level tinyint'<br />
<br />
SET @IntVariable = 35<br />
EXECUTE sp_executesql @SQLString, @ParmDefinition,<br />
@level = @IntVariable<br />
<br />
SET @IntVariable = 32<br />
EXECUTE sp_executesql @SQLString, @ParmDefinition,<br />
@level = @IntVariable<br />
Hope this will serve the purpose.

Hi Everybody!
I am using VB6.0 & SQL Server 7.0
Following is my database Connection code
Dim db As ADODB.Connection
Dim rs As ADODB.Recordset
Dim sql As String
Set db = New ADODB.Connection
db.Provider = "SQLOLEDB"
db.ConnectionString = "server=SUNANDA;uid=sa;pwd=ranjita1;database=crm"
db.Open
Set rs = New ADODB.Recordset
sql = "Select * from AccountHead"
Set rs.ActiveConnection = db
rs.CursorLocation = adUseClient
rs.CursorType = adOpenStatic
rs.LockType = adLockOptimistic
rs.Open sql, , , , adCmdText
I have placed navigation buttons on my form, but the Next & Previous buttons are not working properly.
When I first time clicks the Next button , the recordset goes to the next record but when I click it second time, the record doesn’t get changed.
When I press the previous button, the recordset points to the first record, instead of pointing to the previous record.
Here is my code for navigational buttons :
Public Sub MoveFields()
txtAcId.Text = rs("AcHeadID")
txtAcName.Text = rs("AcHeadName")
txtAcMobile.Text = rs("Mobile")
txtAcEmail.Text = rs("EmailID")
End Sub
Private Sub cmdFirst_Click()
rs.MoveFirst
MoveFields
cmdPrev.Enabled = False
cmdNext.Enabled = True
End Sub
Private Sub cmdLast_Click()
rs.MoveLast
MoveFields
cmdNext.Enabled = False
cmdPrev.Enabled = True
End Sub
Private Sub cmdNext_Click()
rs.MoveNext
If rs.EOF Then
rs.MoveLast
cmdNext.Enabled = False
End If
MoveFields
cmdPrev.Enabled = True
End Sub
Private Sub cmdRemove_Click()
rs.Delete
rs.MoveNext
If rs.EOF Then
rs.MoveLast
End If
End Sub
Private Sub cmdPrev_Click()
rs.MovePrevious
If rs.BOF Then
rs.MoveFirst
cmdPrev.Enabled = False
End If
MoveFields
cmdNext.Enabled = True
End Sub
Pls. tell me, where I am wrong.
Thanks

Hi
Dear Please first check where you write the code for recordset and connection.
Then try following code for your record movement
Next record
if not rs.eof then
rs.movenext()
....
end if
previous record
if not rs.bof then
rs.moveprevious()
.....
end if
If the problem is there then please post new message with you complete form code so I can sort your issue.

:(Hi Everybody!

I have placed buttons on the form to Add, Delete, Edit and Update the records of the table. But in the click event of the Update button, the recordset is not supporting the Edit method. The only method it is showing in (VBA) the dropdown list is EditMode.
How will I then Edit the records?
Pls. help me out.
Thankyou.

Hi
Dear please concentrate on your following code
rs.CursorType = adOpenStatic
As you had open the cursor in Static mode there is no edit permission for this record set.
You gave to open the recordset in non static mode.

Hi
This is the tested code so please use it
Private Sub Form_Load()
Dim db As ADODB.Connection
Dim rs As ADODB.Recordset
Dim sql As String
Set db = New ADODB.Connection
db.Provider = "SQLOLEDB"
db.ConnectionString = "Provider=SQLOLEDB.1;Password=thk;Persist Security Info=True;User ID=thk;Initial Catalog=Dhanavantari;Data Source=TUSHAR"
db.Open
Set rs = New ADODB.Recordset
sql = "Select * from WardMaster"
Set rs.ActiveConnection = db
rs.CursorLocation = adUseServer
rs.CursorType = adOpenDynamic
rs.LockType = adLockPessimistic
rs.Open sql, , , , adCmdText
End Sub
on Save client button
rs.Fields(1) = trim(txtwardname.text)
rs.Fields(2) = val(txtrate.text)
rs.Update
So now you can edit the recordset and then update it
ADO is the connected type of recordset so you can update one record at a time.
If you have some other problem which i had not understand the please brief it
regards

Hi,
I have a stored procedure with 1 parameter.
The value that I pass to the parameter is a select statement.
The question is how do I execute this select statement that is passed as parameter that returns the rows?
Thanks and Regards,

Hi,
You can use sp_executesql to execute the sqlquery which is in a variable.

CReate proc test (@sName Char(4))

end
To execute this
EXEC Test 'Amit'

Hi,
probably the question was that there is a sql statement which is there in the variable and how to execute that. Thats why I have given that solution. To execute a stored procedure is the same what you have given.

Say the user has a copy of her database (let’s call it MyData.mdb) on her PC. There is also a copy of that database on a central server website. Now what I want to do is have the user edit that database on her PC and then hit a “Synch” button, which will connect to the web server, updating the database there. I don’t want to have to re-upload the entire MyData.mdb every time What’s some industry methods for doing this? Can someone point me to a good article or tutorial? Thanks.
