In which system table the information about the optional parameters passed to stored procedure are stored.
I know about the tbl_columns and all that stuff. From where can i can come to know the parameter is mandatory or optional.

How do I specify optional parameters when writing CLR based Stored Procedures in C#?
View 16 Replies View RelatedHi all,
Can anyone please tell me what is the best way to handle optional parameters in a stored procedure which will ensure a good execution plan? I ask this as I have to create a stored procedure with six optional parameters and I'm getting a little concerned that, apart from the parameter issue, I'm going to have a lot of if else statements. Is there an easy way of doing all this?
Thanks
Everyone,I have an application that pulls a list of employees into a web form. I use the same stored procedure to search for employees by various demographic characteristics, and have set all of these search parameters to be optional in the stored procedure.Everything works fine when I pull the entire list (without declaring any select parameters). However, on my Search page, I have declared a number of SelectParameter (ControlParameters, to be specific) objects and mapped each one to its respective control (text boxes and a checkbox). When I attempt a search, the SqlDataSource does not select any records unless I specify an argument for ALL of the search parameters. If I omit even a single search value, the page just posts back and does not pull any information from the database. I have verified with SQL Profiler that it is not attempting to hit the database.I have experimented with various declarations in the ControlParameter object, including the DefaultValue and ConvertEmptyStringToNull items. If I specify a non-empty string as a DefaultValue for all of the parameters, it will perform the query, but it does not query if I use an empty string as a default value - unless my user specifies a value in the form. Any ideas?ThanksTim

ALTER PROCEDURE [dbo].[stream_StoreFind]

AS
SELECT Stores.StoreName ,StoreCategories.storeIDFROM Stores INNER JOIN
StoreCategoriesON
Stores.storeID = StoreCategories.storeID INNER JOIN
SubCategories ON
StoreCategories.subCategoryID = SubCategories.subCategoryID WHERE
My problem is how will i pass the parameters into the statement, taking into fact that sometimes they may be optional. Thank you
I have the following stored procedure:
Code Block
CREATE PROCEDURE udsp_td_queryowner
@state varchar(10) = NULL,
@businesstype varchar(20) = NULL,
@size int = NULL,
@sortorder varchar(20) = 'state'
AS
SELECT gl_t.state AS [State],
gl_t.business_type AS [Business Type],
gl_t.lowsize AS [Low Size],
gl_t.highsize AS [High Size],
e.InternetAddress AS [Owner]
FROM gl_territory gl_t JOIN employee e ON gl_t.employeenumber = e.EmployeeNumber
WHERE state = COALESCE(@state, state) AND
business_type = COALESCE(@businesstype, business_type) AND
COALESCE(@size, lowsize, highsize) between lowsize AND highsize
ORDER BY CASE WHEN @sortorder = 'state' THEN gl_t.state
WHEN @sortorder = 'business type' THEN gl_t.business_type
WHEN @sortorder = 'owner' THEN RTRIM(e.FirstName) + ' ' + RTRIM(e.LastName)
END ASC,
CASE WHEN @sortorder = 'low size' THEN gl_t.lowsize
WHEN @sortorder = 'high size' THEN gl_t.highsize
END ASC,
CASE WHEN @sortorder = 'statedesc' THEN gl_t.state
WHEN @sortorder = 'business typedesc' THEN gl_t.business_type
WHEN @sortorder = 'ownerdesc' THEN RTRIM(e.FirstName) + ' ' + RTRIM(e.LastName)
END DESC,
CASE WHEN @sortorder = 'low sizedesc' THEN gl_t.lowsize
WHEN @sortorder = 'high sizedesc' THEN gl_t.highsize
END DESC
What it allows me to do is enter in any number of the variables when running the stored procedure. For example, EXECUTE udsp_td_queryowner @state = 'IA' would give me everything in the table in the state of IA regardless of the other field values. Likewise, if I ran EXECUTE udsp_td_queryowner @state = 'KY', @size = 15 it would return the records that are in KY and the size of 15 is in the range of the low and high value.
If I run the first example in Query Analyzer I get 53 records from the data I have. It returns every record that has IA as the state. I run the same thing in Reporting Services and all I get is 3 records. Just the 3 records for the state of IA where the business type is either null or blank (I can't tell.) If I allow all of the variables to accept Nulls then it returns the correct data. However, I would like to find a better alternative because when the report is run it returns all of the records in the table initially and if they user wants to enter in any parameters they have to toggle off the null box for the corresponding paramter.
Any ideas?
Using the following:
SQL Server: SQL Server 2012
Visual Studio 2012
I have created an SSIS package where I have added an Execute SQL Task to run an existing stored procedure in my SQL database.
General Tab:
Result Set: None
Connection Type: OLE DB
SourceType: Direct Input
IsQueryStoredProcedure: False (this is greyed out and cannot be changed)
Bypass Prepare: True
SQL Statement: EXEC FL_CUSTOM_sp_ml_location_load ?, ?;
Parameter Mapping:
Variable Name Direction Data Type Prmtr Name Prmtr Size
User: system_cd Input NVARCHAR 0 10
User: location_type_cd Input NVARCHAR 1 10
Variables:
location_type_cd - Data type - string; Value - Store (this is static)
system_cd - Data type - string - ??????
The system code changes based on the system field for each record in the load table
Sample Data:
SysStr # Str_Nm
3 7421Store1
3 7454Store2
1815061Store3
1815063Store4
1615064Store5
1615065Store6
1615066Store7
7725155Store8
STORED PROCEDURE: The stored procedure takes data from a load table and inserts it into another table:
Stored procedure variables:
ALTER PROCEDURE [dbo].[sp_ml_location_load]
(@system_cd nvarchar(10), @location_type_cd nvarchar(10))
AS
BEGIN .....................
This is an example of what I want to accomplish: I need to be able to group all system 3 records, then pass 3 as the parameter for system_cd, run the stored procedure for those records, then group all system 18 records, then pass 18 as the parameter for system_cd, run the stored procedure for those records and keep doing this for each different system in the table until all records are processed.
I am not sure how or if it can be done to pass the system parameter to the stored procedure based on the system # in the sys field of the data.
I have an issue with using multiple parameters in SQL Reporting services where data is passed in from a stored procedure
When running the report in design mode - I can type in a parameter sting and it runs fine
In the report preview screen I can select single parameters by ticking the drop down list and again it runs fine
as soon as I tick more than one I get an error
An error occurred during local report processing
Query execution failed for data set €˜data'
Must declare the scalar variable '@parameter'
Some info...
The dataset 'workshop' is using a sproc to return the data string?
I get multiple values back fine in the sproc using this piece of code
(select [str] from iter_charlist_to_table( @Parameter, DEFAULT) ))
I have report parameters set to Multi-Value
Looking through the online books it says...
You can define a multivalued parameter for any report parameter that you create.
However, if you want to pass multiple parameter values back to a query, the following requirements must be satisfied:
The data source must be SQL Server, Oracle, or Analysis Services.
The data source cannot be a stored procedure. Reporting Services does not support passing a multivalued parameter array to a stored procedure.
The query must use an IN clause to specify the parameter.
Am I trying to do the impossible ?
I am writing a stored procedure that takes in a customer number, a current (most recent) sales order quote, a prior (to most current) sales order quote, a current item 1, and a prior item 1, all of these parameters are required.Then I have current item 2, prior item 2, current item 3, prior item 3, which are optional.
I added an IF to check for the value of current item 2, prior item 2, current item 3, prior item 3, if there are values, then variable tables are created and filled with data, then are retrieved. As it is, my stored procedure returns 3 sets of data when current item 1, prior item 1, current item 2, prior item 2, current item 3, prior item 3 are passed to it, and only one if 2, and 3 are omitted.I would like to learn how can I return this as a one data set, either using a full outer join, or a union all?I am including a copy of my stored procedure as it is.
I need to create a SP that will accept a varying number of input parameters. A form that the user completes has a several controls that serve to narrow the number of records returned. The more parameters given, the fewer rows returned. In the past I have accomplished this by dynamically building an SQL statement. I dosen't appear possible to pass an SQL statement in a variable to a SP. Any help or pointers would be appreciated.

Is it possible to write a stored proc with optional parameters?
For example consider the following SELECT
SELECT FLD1, FLD2 FLD3 FROM TBL1
I'd like to add optional parameters to that statement so that if they wanted to narrow down the results by providing criteria for some fields they could - but didn't have to.
Is this possible?
I have a stored procedure that updates about a dozen rows.
I have some overloaded functions that I should update different combinations of the rows - 1 function might update 3 rows, another 7 rows.
Do I have to write a stored procedure for each function or I can I handle it in the Stored Procedure. I realise I can have default values but I the default values could overwrite actual data if the values are not supplied but have been previously written.
Many thanks for any guidance.

I've created a search page in my asp.net app that allows the user to enter optional parameters to narrow down the result set. It looks something like:Find all parts where: manuafacturer: <dropdownlist>ANY | manufacturer 1 |... </dropdownlist> model: <dropdownlist>ANY | model 1 |... </dropdownlist> cost: between <textbox> and <textbox> dollarsCurrently I create the SQL command on the fly building the WHERE based on what the user selects. For example if in the form above they select manufacturer = manufacturer1 model = ANY cost = between 10 and 15the WHERE string is ... WHERE manufacturer='manufacturer1' AND cost BETWEEN 10 AND 15Since the user doesn't care about model I leave it out of the WHERE. OK so here is my question. I want to move my queries to strored procedures however I'm not sure how to create the query since it changes based on what the user enters. Using the example above I'm assuming I can create one query with 4 parameters however what value would I use for ANY? parameter1 (manufacturer) = "manufacturer1" parameter2 (model) = ??? parameter3 (price low) = 10 parameter4 (proce high) = 15I see there is an ANY operator in T-SQL but it doesn't look like the right thing to use. Should I use LIKE '%'? Seems that using LIKE would result in addition overhead.ThanksSimon
View 2 Replies View RelatedHi,I'm using c# with a tableadapter to call stored procedures. I'm running into a problem where if I have over a certain byte size or number of parameters being passed into my stored proc I get an exception that reads: "Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized." If I remove one parameter, the problem goes away. Has anyone run into this before? Thanks,Mark
View 3 Replies View RelatedHi I have a textbox, and a dropdown list, What i am trying to do is give the user the option of searching based on both (textbox and dropdownlist) or one or the other(textbox or dropdownlist), What i am experiencing though is that when i enter a word into the textbox and select a value from a dropdownlist i get no search results even though the word is "like" the text in the database, it will only work when i type out the full word. What is wrong with my stored procedure, here it is;
SELECT S.storeID, S.storeName
FROM dbo.Stores AS SINNER JOIN dbo.storeCategories AS SC
ON S.storeID = SC.storeID left JOIN dbo.SubCategories AS SU
ON SC.subCategoryID = SU.subCategoryID
WHERE S.storeName like ISNULL(@storeName + '%', S.storeName)
AND SU.subCategoryID = ISNULL( @subCategoryID, SU.subCategoryID)
I want the procedure to check for the existence of a paramter and if it isthere, it will process these instructions, otherwise it will process theseinstructions. Any ideas? Thanks for your advice.Regards,CK
View 7 Replies View RelatedIf I do this with a function and multiple inline sql statements, I could probably do it much easier, but here at work, sprocs are required, and I can't seem to stretch my knowledge and Google searches far enough to find the answer. Plus, I don't really think that creating 4 separate sProcs is the most efficient way of doing this
I need to select and return 8 columns from a table, but the problem is I need to feed the sProc parameters in such a way, that I can use different criteria in the Where Clause.
for instance, I need to combine these 4 select statements into one:1. Select (fields) from (table) Where TechID=@TechID and Status=@Status)2. Select (fields) from (table) Where TechID=@TechID3. Select (fields) from (table) Where OrdNum=@OrdNum3. Select (fields) from (table) Where CustNum=@CustNum
In all instances, the fields and the table are the same - how can I combine all these possible Where clauses (if/then - Select Case?) so that it's only one Stored Procedure?
(or, is this even possible?)
Hi,
We have an application written in ASP that calls a MS-SQL stored procedure and passes several parameters. Once in a while, we get this error, but most of the time it works. We can also run this in SQL query analyzer without ever a problem. We've looked at the obvious and found nothing wrong.
Please help! Any suggestions are appreciated.

When using JDBC is it possible to ignore input parameters in a stored procedure if they have default values?
I can create a string and execute a PreparedStatement but I'd like to use a Callable Statement.
Hi there i really cant understand why this should be a problem... it seems that i cant create a table from a stored procedure when passing the tablenam from application like this...

THIS CANT BE TRUE !!!!!!!!
I have a scenario where I need to compare a single DateTime field in a stored procedure against multiple values passed into the proc.So I was thinking I could pass in the DateTime values into the stored procedure with a User Defined Table type ... and then in the stored procedure I would need to run through that table of values and compare against the CreatedWhenUTC value.I could have the following queries for example:
WHERE CreatedWhenUTC <= dateValue1 OR CreatedWhenUTC <= dateValue2 OR CreatedWhenUTC <= dateValue 3
The <= is determined by another operator param passed in. So the query could also be:
WHERE CreatedWhenUTC > dateValue1 OR CreatedWhenUTC > dateValue2 OR CreateWhenUTC > dateValue3 OR CreateWhenUTC > dateValue4
Currently i am using SQL Server 2012 Import/Export Wizard to upload data to sql tables manually. However i was trying to write a procedure to update that table. and on the time of execution, if i can pass excel. Is there any way to pass excel to stored procedure parameter?

Using a string of IDs passed into a stored procedure as a VARCHAR parameter ('1,2,100,1020,') in an IN without parsing the list to a temp table or table variable. Here's the situation, I've got a stored procedure that is called all the time. It's working with some larger tables (100+ Million rows). The procedure passes in as one of the variables a list of IDs for the large table. This list can have anywhere from 1 to ~100 IDs passed to it.
Currently, we are using a function to parse the list of IDs into a temp table then joining the temp table to get the query:
CREATE PROCEDURE [dbo].[GetStuff] (
@IdList varchar(max)
)
AS
SET NOCOUNT ON
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
[Code] .....
The problem we're running into is that since this proc gets called so often, we sometimes run into tempDB contention that slows this down. In my testing (unfortunately I don't have a good way of generating a production load) swapping the #table for an @table didn't make any difference which makes sense to me given that they are both allocated in the tempDB. One approach that I tried was that since the SELECT query is pretty simple, I moved it to dynamic SQL:
CREATE PROCEDURE [dbo].[GetStuff] (
@IdList varchar(max)
)
AS
SET NOCOUNT ON
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
[Code] ....
The problem I had there, is that it creates an Ad Hoc plan for the query and only reuses it if the same list of parameters are passed in, so I get a higher CPU cost because it compiles a plan and it also causes the plan cache to bloat since the parameter list is almost always different. Is there an approach that I haven't considered that may get the best of both worlds, avoiding or minimizing tempDB contention but also not having to compile a new plan every time the proc is run?

View 1 Replies View RelatedOn many reports I have optional parameters, for example if the employee is filled in it will run for that employee but if it's null it runs for all employees. Which is the best way to handle this?

I am using Oracle 7.3 against SSRS. I have created an inline query with 7 unnamed parameters. I have named them in SSRS parameters window and selected NULL and ALLOW BLANK check boxes for all the parameters.
a.)
What I think should happen is: I should be able to pass the combination of parameters NOT all of them, because I have selected NULL and Blank check boxes. But in my case the query is not giving me any results if I pass 2 of 7 parameters. I can see the results only when I pass all 7 parameters.
Please Help me...

Is there a way I can create a Dynamic WHERE condition using ORACLE 7.3 as database and OUT REF cursor as out parameter for generating parameters. An Example would be great.......

I'm rewriting a T-SQL function that is called "Proper Case" which takes in a sentence and returns the sentence with the first letter of each word capitalized.
The new CLR(C#) function implements new functionality where it can take a string and turn it into a properly cased string, sentence cased string, lower cased, upper cased, and toggle cased.
The function takes in one parameter, the string, and the casing type, a string also. I want the casing type to be optional where if it's not passed in it defaults to "proper". The reason why I want this is so that I can easily replace the existing T-SQL function without having to add an extra parameter to each call to make life easier.
I know you can do it for SQL stored procedures, but I seem to be having trouble with the function.
Things I've tried:
1) Overloading the function in C# doesn't work because SQL functions don't like overloaded functions.
2) Attempting to set a "default" value to the parameter.
a) casingType nvarchar(4000) = 'proper'
b) default casingType nvarchar(4000) = 'proper'
Any ideas would be greatly appreciated. Thanks!
