Is it possible to replicate this code from a stored procedure in a SSRS dataset?
exec #dtEffective = dbo.selUpdEnv 'PrevBusDt','=',#cdUser,'N'
What I'm trying to do is save the effective date in a variable and display the date in a textbox.
I tried creating a parameter called dtEffective and use it in the dataset. But it didn't save the value.
Create a new data set with the [dbo.sqlUpdEnv] as the record source. Note that #cdUser will need to be populated first since you're passing it in, so make sure that's above #dtEffective in the parameter list. In your #dtEffective parameter, set the Default Value to the result of the data set.

I am working on a stored procedure activity to load data into one of my table. The procedure expects an int parameter to be passed and the value for this comes from the lookup output firstrow field. But when I pass the lookup output value for the parameter the pipeline is not getting executed. I have tried to convert the values as well and even used a variable to store. Any option to process the same?
Regards,

Can you send the detailed error when you try to execute the pipeline?
Thanks,

How do I save procedure out parameter value to variable for later reuse in sqlworkbench/j script?
It is possible to run a stored procedure with out parameters using WbCall
However, the result of that can not be used to be stored into a Workbench variable.
That is only possible with "regular" queries (SELECT) that return a result set.
So I have created a Stored Procedure and I'am linking it to crystal report.
My stored procedure has 2 Parameter StartDate AS DATIME and EndDate AS DATEIIME.
Everything is good, when I run the Crystal report it ask me the parameters and it's working pretty fine.
The change I want to bring :
So my question is that, is it possible to change the Paramter format. What do I mean by that ?
In Crystal, if you create a parameter DataType Date you can set the property
Allow Range Values to TRUE ...
But the paramters that come from the Stored Procedure wont allow me to set those properties
Is there a way I can allow my parameter that I receive from the Stored Procedure to have a Range value when I run the CR ?
Many Thanks
I am getting capability error whenever I am trying to set active property tue. I want to bind the grid with the stored procedure that takes one parameter.
If I do it through TQuery How do I specify the fields. I am using wwDBGrid.
MessageMembershipSelectQuery.Params[0].AsString :=
custQuery.FieldByName('cust_code').AsString;
MessageMembershipSelectQuery.Active := True;
Please guide
Replace you Query component by a StoredProc component. Also, check your parameter data type. If it is indeed a string parameter, then it´s Ok to use AsString, but if the parameter has a different data type, like Integer, for instance, then you should assign it´s value by using, for instance, AsInteger.
I have to create a program in Delphi using Access 2003 .mdb file as data repository.
The Access database has a table with a boolean (Yes/No in Access) field called "original".
I have mapped this field to a TDBCheckBox which shows checked for true and unchecked for false, and shows a half greyed check is the field has not been set.
What I want is oncreation of the field for the field to be set to false (checkbox unchecked) and save the field value as false IF the user has not explicitly set the field.
I have tried if (DVDQuery.FieldByName('Original').AsBoolean <> True) and (DVDQuery.FieldByName('Original').AsBoolean <> False )
then DVDQuery.FieldByName('Original').AsBoolean := False;
But this does not work for new records. I use a query to access the dataset as there a large number of dynamically created where statements to filter the dataset.
ANy help guidance is greatly appreciated.

Can you change the structure in the database? The proper place for default values is in the column definition. If you can update the structure, change the field to have a default value of "No". You will then never need to do any coding around this issue, and your data will be guaranteed correct even if entered directly through Access.
If you need to check the value in code, use if DVDQuery.FieldByName('Original').IsNull to determine whether the field is empty or not.
Finally, if you must change the value in code rather than as a database default, do it in the appropriate TDataset event (AfterInsert, AfterScroll, etc).
Check if the field is set a value or not in the BeforePost event of the DataSet:
procedure TForm1.DVDQueryBeforePost(DataSet: TDataSet);
begin
if DVDQuery.FieldByName('Original').IsNull then
DVDQuery.FieldByName('Original').AsBoolean := False;
if still relevant, check the status field of the field. It should be cbChecked, cbUnchecked or cbGray, which is what you are looking for.
