T-SQL (SS2K8) :: How To Modify Procedure For Input Is Null Or Zero
Apr 30, 2014
I am creating web application for state and dist wise map. I've the tables like
create table ind_state
(
ind_stat_id int,
ind_state_name varchar(50)
)
insert into ind_state values ('1','Pondi')
[Code] .....
My output is depends on the dist selection so made procedure
alter procedure LAT_TEST_DYNAM0
@dist_id int
as
begin
create table #temp (pincode varchar(10) ,latitude numeric(18,10),longitude numeric(18,10) ,descp varchar(5000))
if @dist_id!=0
[Code] ....
Myself doubt is when @dist_id is null or "0" how to show default value ?
Otherwise above my code is correct?

my stored procedure is
create procedure t1 (@a int,@b int,@c int,@d int,@e int,@f int)
as
begin
select no,name,department from emp where a = @a and b =@b orc =@c or
d = @d or e = @e or f = @f
end
my problem is while executing i may get null values as input to the stored procedure .
how to validate them ? any ideas .
are there any arrays.
if c and d are null then my condition would be
where a = @a and b =@b or e = @e or f = @f
how many loops shall i have to write.

Hello.
I've built a sample CLR function with the following declaration....
CREATE FUNCTION GetManager(@DeptCode nvarchar(3))
RETURNS nvarchar(1000)
WITH RETURNS NULL ON NULL INPUT
AS
EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager
And it works as expected, except when I use NULL:
DECLARE @MyManager nvarchar(1000)
EXEC @MyManager = dbo.GetManager NULL
PRINT @MyManager
It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.
I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?

Hi,
I'm trying to extend the usage of the code below. This method returns a variable of type SQLParameter and what I want is to accomodate even a check for a null in the parameter. This is a code which I got from one of my co-workers who isn't anymore working here. Any help would be appreciated. I do not want to throw an exception here when a field's type doesn't fall into one of the categories below. The method where this methos is called is the first part of my below code. Any help would be appreciated.
Part 1
private void AddCommandParameters(SqlCommand Comm, string sProcName, ArrayList aParams)

int i = 0;
if(dr.Read())
{
while(dr.Read())
{
//CLOSING PARENTHESIS

hi,
I am using sql as a back-end server. My application requires to insert a default string values when the user do not provide any input or if the inpur is NULL. I have used the following code, but the defaul values are not inserted. I am not getting the desired result.
CREATE TABLE Employees1 (
EmployeeName varchar(50),
State char(3) NOT NULL DEFAULT 'NSW' ,
PostalCode int default 2000,
Country varchar(32) NOT NULL default 'Australia');
insert into Employees1 values ('diana', ' ' , 2,' ' )
The output is: EmployeeName State PostalCode Country
diana 2
Can anyone tell me what is that i am missing?

I have to create a report and I want all activity for the previous month.
I need to calculate the First and Last Day Prior Month to be used as Input Parameters.
Would something like this be the case or is there a better solution?
[code="sql"]
SELECT DATEADD(month, DATEDIFF(month, -1, getdate()) - 2, 0) as FirstDayPreviousMonthWithTimeStamp,
DATEADD(ss, -1, DATEADD(month, DATEDIFF(month, 0, getdate()), 0)) as LastDayPreviousMonthWithTimeStamp
[/code]
I was thinking get the first day of the previous and current month to exclude the Timestamp and use a less then first day of current month?

I'm attempting to use the Web Service task to call a method provided by a vendor. The inputs are all simple types so that helps a lot, but for one input it's a string array. If I enter a single string value for a given id using the array dialog, the method works fine.
However if I try to change the input to use a variable to provide the value it fails. I'm assuming that you can't create a variable to return a string array. Please let me know if this is the case or if I'm missing something obvious ;-)
In addition, is there a way to specify a null value for an input? Currently there doesn't appear to be a way to do this in SP2. I tried leaving the string empty which didn't work and I tried using a variable with expression "NULL(DT_WSTR, 1252)" but that failed too.

Do I have to use condition split?, then union all?
if in script, I can use update from <tablename> Set column = isnull(column, 'NA'). It's so simple.
I'm also wondering can we run SQL Script against input dataset in a SSIS component?

I want to write an Query for a report that has 7 parameters. I want to allow Null for these parameters but at the same time in the Query i want to put an AND condition for all the parameters. I cannot put an OR condition.
For Example;
If i have a report with 2 parameters then the script will have 2* 2 If conditions
something like:-
if( @parameter1 is not Null and @parameter is not Null)
select A, B, C
From Table 1
Where parameter1 = @parameter1 and parameter2 = @prameter2
if( @parameter1 is not Null AND @parameter2 is Null)
select A, B, C
From Table 1
Where parameter1 = @parameter1
If( @parameter1 is Null AND @parameter2 is Not Null)
select A, B, C
From Table 1
Where parameter2 = @parameter2
If( @parameter1 is Null AND @parameter2 is Null)
select A, B, C
From Table 1
For 7 parameter there will be way too many If conditions. Is there an better approch to write a Query for such a situation?

Hi,
I'm pretty new to ASP.NET and VB, but I'm working on a project which is essentially a staff directory. Using VS 2005, I've setup a basic grid view which connects to an object which connects via a data layer to a SQL database with Name, Surname, Email, Extension No and Department fields.
I have it working so that if a user enters a name and surname for example, it will return all records with either the name matching or surname matching input parameters. What I want to do is to set up a SQL query which is:
SELECT * FROM records WHERE (Name LIKE @Name) AND (Surname LIKE @Surname) AND (Email LIKE @Email) AND (Dept LIKE @Dept)
so that if the user only enters the first name and surname for example as above, it ONLY returns the record which matches the first name and surname and not all records with either/or. One way I've thought of to do this is to convert the empty fields to "Nothing" so that it fullfils the search parameter for the empty fields. If someone can explain how to do this, or can suggest a better way, I'd be grateful.
Cheers,
Tom

Hi,
Below is the SP that I want to modify it such that it does another thing apart from what its doing now. I want to to delete all the records corresponding to the BpDate value before this insert happens. by meaning deleting all the records, I meant to say delete all records where BpDate = @BpDate and SiteCode = @SiteCode.
CREATE PROC CabsSchedule_Save
@JulianDate smallint,
@SiteCode smallint,
@BpDate smallint,
@CalendarDay smallint,
@BillPeriod smallint,
@WorkDay smallint,
@CalDayBillRcvd varchar(30),

VALUES
(@JulianDate, @SiteCode, @BpDate, @CalendarDay, @BillPeriod, @WorkDay, @CalDayBillRcvd, @Remarks)

When I right click on the stored proc and select "Modify", the code opens - however any attempt to save creates a local .SQL file. How can I save these changes to the stored procedure on the server?

Hi,
I'm from Argentina. I'm not an expert at all in SQL, I know very little about it. I've read in MSDN Library that in order to edit a stored procedure I must right-click the procedure to modify, and then click Design.
I'm using SQL Server Management Studio (not Express) and I don't see any "design" option. I do see a "modify" option. I clicked there and modified just a number I wanted to. Once modified I clicked on the X button to shut the file hoping the system would ask me if I wanted to save the changes made. When I clicked "yes" the file saved into "my documents > sql management studio > proyects".
I checked the original Store Procedure file inside "Programmability > Stored Procedures" and obviously it wasn't altered. I have now a file called "SQLQuery31" in "my documents > sql management studio > proyects" that seems to have the modification made.
Why do I have it there (inside My Documents) instead of modifying the original one? What must I do to get that stored procedure modified?
Thanks from Argentina !!

Our ERP vendor is helping us migrate from one version of their product to another. In the new version, they have added some columns and changed a few data types in several existing tables.
They sent us a list of the modifications that were necessary, which we did (painstakingly) by hand. But, for other reasons the update failed and we have to start anew.
This got me thinking: is there any way to do this kind of update via a script/stored procedure? I don't have their exact changes handy, but it was stuff like the table "inmast" needs a column of varchar(50) called "lotc" added to it, and the "intime" table needs the datatype of columns "Mon" "Tue" "Wed" changed from text to varchar(50), stuff like that.
Is it possible to do stuff like that in a SP?

I would like to force a column to be null all the time. I cannot alter the table structure or alter the code that inserts data.
create table dbo.tblCustomer
(
CID int IDENTITY(1,1) not null,
Fnamevarchar(20) not null,
Lnamevarchar(20) not null,
Extravarchar(20) null
[Code] ....
So when this is executed the field Extra is always NULL
INSERT INTO tblCustomer (Fname, Lname, Extra)
VALUES ('bob', 'smith', 'ignore'), ('jane', 'doe', 'empty')
update dbo.tblCustomer set Extra = 'something'
If I've understood After triggers correctly the data will be written and the trigger will fire and overwrite. To avoid 2 writes
I could create an INSTEAD OF trigger
CREATE TRIGGER TR_I_Customer
ON tblCustomer
INSTEAD OF INSERT AS
BEGIN
SET NOCOUNT ON
INSERT INTO tblCustomer
(Fname, Lname, Extra)
SELECT Fname, Lname, NULL
FROM Inserted
END
This will not write the "extra" field twice. However if a new Nullable column were added; it would be v.easy to forget to update the Instead Of trigger. Everything would still work OK but I would be effectively ignoring the new column as well.
What I would like in the instead of trigger is do something like this...
UPDATE INSERTED SET Extra=NULL
Continue with insert without supplying column /value list.
What would be the best way of achieving this, trigger is the only way I could think of?

I am working on some data that is JOINing to another table. Not a big thing. In the child table, there are different values for a single ID. I want to be able to select the Max ColorID that is Not Null, for each distinct CarID. The CarID is what I am joining the other table with. I need selecting the distinct row with the Max ColorID that is not Null. All this data is made up, so nothing looks logical in the design.
DECLARE @ColorList TABLE

I added a new field to an existing ETL process which uses SSIS to ingest a CSV file. The new field in the file, Call_Transaction_ID, will not always be populated for every record and so can be NULL or empty for certain records.
Here's the problem:After the file is extracted into a staging table, the Call_Transaction_ID field is showing blank or empty when it has no ID for that particular record. The problem is when I try to then ETL this data into a fact table - I'm trying to set the Call_Transaction_ID field to -1 if it is NULL or empty, however SQL Server doesn't see the field as empty even though there is no value in the field so -1 will NEVER return.
Using a WHERE DATALENGTH(Call_Transaction_ID) = 0 returns 0 records, again because SQL Server doesn't see the field as empty or NULL.
What do I do now to get around this? How do I fix it?

I have the following tables:
tbl_Person (personID, first_name, lastname)
tbl_student (studentID)
tbl_stupar (personID, StudentID, relationship)
tbl_person_Phone (personID, phone)
I need to list all students who have both parents phone number is null. The parent relationship values 1 and 2 indicates the person is either Mom (value 2) or dad (value 1) of the student. Note: I am using student parent as an example to write my query.

I believe query optimizer can leverage the predicate used to define the filtered index. But I came to a situation that's not true:
USE tempdb;
GO
IF OBJECT_ID('Employees') IS NOT NULL
DROP TABLE Employees;
GO
CREATE TABLE Employees
[Code] ....
If we take a look at the query plan. we'll find an unnecessary Nested Loop and Key Lookup operator there with the IS NULL predicate.
Ironically, If I change the IS NULL to IS NOT NULL in both the index and Query, everything goes fine.

I use the merge statement in a sproc to insert, update and delete records from a staging table to a production table.
In the long sql, here is a part of it,
When Matched and
((Student.SchoolID <> esis.SchoolID
OR
Student.GradeLevel <> esis.GradeLevel
OR
Student.LegalName <> esis.LegalName
OR
Student.WithdrawDate <> esis.WithdrawDate
Student.SPEDFlag <> esis.SPEDFlag
OR
Student.MailingAddress <> esis.MailingAddress)
Then update
Set Student.Schoolid=esis.schoolid,
.....
My question is how about if the column has null values in it.for example
if schoolID is null in production table is null, but in staging table is not null, will the <> return true.or if either side of <> has a null value, will it return true.
I don't want it to omit some records and causing the students records not get updated.If not return true, how to fix this?

I have a table with data in two columns, item and system. I am trying to accomplish is we want to compare if an item exists in 1, 2 or all systems. If it exists, show item under that system's column, and display NULL in the other columns.
I have aSQL Fiddle that will allow you to visualize the schema.
The closest I've come to solving this is a SQL pivot, however, this is dependent on me knowing the name of the items, which I won't in a real life scenario.
select [system 1], [system 2], [system 3]
from
(
SELECT distinct system, item FROM test
where item = 'item 1'
) x
pivot
(
max(item)
[Code]...
