If Statements In SP
Sep 21, 2006
I use SQL Server 2005.
I want to create a SP "Search". With this function a user can serach the member database on several criteria: age minimal, age maximal, name, city..
BUT these criteria do not necessarily have to be defined by the user, so it might be that a user searches for all members whose age is between ageMin and ageMax leaving the name and city criteria empty.
So in my SP I have to check whether these values are empty or not. If a parameter is not empty I have to add it to my selection query..
BUT, I know that SQL Server makes an execution plan, and understood that when you use if-statements the procedure needs to be recompiled every time?
Is this true? If so:
how does this work then?
Is there another way for me to still be able to create this SP?

I need to create a brief statement in Design View for SQL 2000.
I successfully wrote "isnull(dbo.Data.Parcel,'')in the Column in Design View, which would ensure that a null value would be listed as a blank. Now I need to have dbo.data.status show as 'C&G' in any instance of data, otherwise it will be listed as blank. I tried writing "isnotnull(db0.data.status,'Homestead', '')", but it does not work.
Is there a simple statement I can write in "column" of design view that can get the results that I need?

I am totally new to creating IF statements inside stored procedures. I am passing some parameters from a ColdFusion form to a SP and if the form is empty for the small date I get an error. I would like to be able to check in the procedure to see if the parameter is empty and if it is set a default value for it. Here is my code.
@JOB1,
@COLLEGEDATE smalldatetime,
If(@COLLEGEDATE <> ''")
@COLLEGEDATE smalldatetime,
ELSE
@COLLEGEDATE = getDate(),
RETURN

Hello,
I have a report with 1 field that I need to sum into 2 different textboxes based on another field's value.
Specifically, Is it simply doing something like this below?
=Iif(Fields!iBB.Value=1, Sum(Fields!Billed.Value)
=Iif(Fields!iBB.Value=0, Sum(Fields!UnBilled.Value)
Which will not get past intellisense checking, -or- do I have to do something different here?
Thanks in advance.

Hi guys! I have these commands that insert into two tables, if condition 1 is met, it will insert into the first table, if the second condition is met, it will insert into the second table.
Is there a way for the insert statements to be merged so that I won't be executing two statements?
Dim update_phase_before As New SqlCommand("INSERT INTO TE_shounin_todokesho_jizen (syain_No,date_kyou,time_kyou) SELECT syain_No,date_kyou,time_kyou FROM TE_todokesho WHERE TE_todokesho.b_a='before'", cnn)
Dim update_phase_after As New SqlCommand("INSERT INTO TE_shounin_todokesho_jigo (syain_No,date_kyou,time_kyou) SELECT syain_No,date_kyou,time_kyou FROM TE_todokesho WHERE TE_todokesho.b_a='after'", cnn)
Thanks.

I'm running a custom built report on .net page Basically there are a lot categories. I need to run SQL statements for and for each category, the catch is these statements are all in loops for i = 1 to 12. Therefore 108 categories X 12 iterations of SQL calls = a little more that 1200 sql calls from one .net page.
There is obviously a major problem with load time and running these reports are painful to the user and the system.
Is there any easier way to possibly pre-compile all the data into a temp database so I wouldn't need to make as many sql calls??????? If so, would a stored procedure handle something like this.
Sorry for being somewhat vague.

I'm trying to combine the following two strings to create a single Insert statement (and thus only generate one record instead of two).
insertString = "Insert comments (uID) Select uID FROM users WHERE uName = @uName"
insertString2 = "INSERT comments (eventID, text) VALUES ( @eventID, @comment)"
I have tried:
Insert comments (uID, eventID, text) SELECT uID FROM users WHERE uName = @uName VALUES (uID, @eventID, @comment)
Individually they work fine, but I can't get the syntax correct to allow them to work together. As you can tell, I'm not very good with SQL, so any help would be greatly appreciated!
Thanks in advance.

I have a web application that has SQL7 as the back end. SQLServer and ORACLE have a feature that allows sql commands to be combined in one statement. Another words I am able to to
SELECT * FROM table_name WHERE id = 2 DROP TABLE other_table
If I type this in a query analyzer It will perform both commands. Is there a way to turn this 'feature' off.
The main reason I want to turn it off is so if a numerical value is sent as a url variable someone can't add the drop table statement or any other sql command to the value of the url variable and have it executed. We have added ample code to trap for this problem but I would like to also handle it at the database level.
Thanks,

Folks,
I'm having some real problems using the OR condition in a very simple SQL statement and could use your help or insight on where the problem lies, or perhaps a workaround.
I have a large flat table in a SQL 7 database with 10 million + records called "HISTORY". I have not installed either service pack 1 or 2. I'm attempting to run a query that references the following four fields which are all non-clustered keys:
EQUIPMENT_NO TEXT 12
CHASSIS_IN TEXT 12
CHASSIS TEXT 12
SVC_DATE_TIME SMALLDATETIME
Here's the SQL statement:
SELECT * FROM HISTORY WHERE (HISTORY.EQUIPMENT_NO = 'XYZ123' OR HISTORY.CHASSIS = 'XYZ123' OR HISTORY.CHASSIS_IN = 'XYZ123') AND SVC_DATE_TIME >= '01/15/00 00:00:00 AM' AND SVC_DATE_TIME <= '02/28/00 23:59:59 PM'
ORDER BY EQUIPMENT_NO
This query takes 11 min. 5 sec. inder the Query Analyzer and ultimately returns the 31 desired records.
If you remove the SVC_DATE_TIME criteria, about 350 records are returned in a matter of seconds. I've also tried variations on the date syntax such as '01/15/00', etc. with no change in the amount of time to execute.
Other queries such as a simple AND condition combining EQUIPMENT_NO and SVC_DATE_TIME are snappy.
Are there known problems/bugs with "OR" conditions in queries that anyone is aware of, particularly with parentheses; am I composing this query incorrectly? Is there some alternate syntax that would work as expected? I can't see where the query shouldn't execute quickly as expected, particularly with all indexed fields involved. I'm stumped! Lend me your expertise. Thanks much.

Hi,
I am having some problems trying to build an sql statement from more than one statement.
Here is the statement
select 'Insert App_Column (Table_ID, Column_Type_Transformation, Column_Name, )
Values (@table_ID,' ,'NULL,', name from payatwork..syscolumns where id in (
select id from payatwork..sysobjects where name like 'Employee_Profile')
order by colorder, ')'
What I am finding is that the bracket at the end of the statement is not appearing - how do I append statements to the end of this sql statement (i've tried various combinations of the + sign and the comma without success.
thanks,
Jim

Hey folks, having a problem here...
I have 2 piece of code designed to do the same thing. My problem is, i'm not getting the same results.
Code 1 where the results are correct
Code:
select Count(*) as TotalCount, Sum(DistAmt) as TotalSum
from table1
inner join table2
on table2.id = table1.id
where MailTypeID = 3
AND MailEventID = 2
and table1.IsActive = 1
code 2 - Y is correct, but Z is not, and not only is it not correct, but it is returning a number which equals more then the total rows from the table.
Code:
select
Y = sum(case when mailtypeid = 3 and maileventid = 2 and IsActive = 1 then distamt else 0 end),
Z = count(case when mailtypeid = 3 and maileventid = 2 and IsActive = 1 then 1 else 0 end)
from table1
inner join table2
on table2.id = table1.id
I have no idea what is going on.
Thanks!

Hi,
Is there a way to use more criteria in a CASE statement other than CASE WHEN expression THEN value ELSE value END
I need to test if the count is greater than 0. If so, then perform the case statement, else return zeros. Currently there are entries where the values are blank. These blank values are causing errors in the application and unfortunately, I am not able to update these values.
So far I have the following, but I am getting an error stating "An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or select list, and the column being aggregated is an outer reference."
Thanks in advance!
Code:
IF @Qid = 4
SELECT @Exp as Status, COUNT(*) AS Total, @CourseID as CourseID,
(SELECT
question
FROM
tableQuestions
WHERE
qid = @Qid) AS Question,
IF COUNT(*)>0 THEN
1.0 * SUM(CASE WHEN A.Q1 > 1 THEN 1 ELSE 0 END) / COUNT(*) AS Positive,
1.0 * SUM(CASE WHEN A.Q1 = 0 THEN 1 ELSE 0 END) / COUNT(*) AS Neutral,
1.0 * SUM(CASE WHEN A.Q1 < 0 THEN 1 ELSE 0 END) / COUNT(*) AS Negative,
1.0 * SUM(CASE WHEN A.Q1 = 0 THEN 1 ELSE 0 END) / COUNT(*) AS NA
ELSE
0 AS Positive,
0 AS Neutral,
0 AS Negative,
0 AS NA
END IF
FROM
table1 A INNER JOIN table2 B ON A.SessionID = B.SessionID
WHERE
(B.CourseID = @CourseID) AND (A.SubmitDate >= @BeginDate) AND (A.SubmitDate <=@EndDate)

Im trying to get some of my queries to run a little faster and i think i have an idea on how but i cant seem to get my and IF statements to work
basically what i want is for the different parts of my WHERE clause to run only if certain variables have a value. so something like this
Code:
SELECT * FROM tablename WHERE
IF LEN(@color) > 0
BEGIN
color = '@color'
END
IF LEN(@size) > 0
BEGIN
AND
size = '@size'
END
so i only want it to limit it by color if @color has a length of more than 0. if there is a better way to do this (other than IF statments) then please let me know.
Im just getting an error saying incorrect syntax near IF

Hi All,
It's probaly still Sunday in most areas, but hope I get a quick response on this 1.....
I'm doing ASP with SQL 2000. And for the moment, I write inline SQL Scripts into my ASP pages. Store procs can only come later ( don't ask why...).
So as most of u will know, if any characther from the textboxes comes with a ' , everything will go haywire!
Thus, I'm using this existing code to solve the prob:
FAddress = Replace(FAddress, "'", "%%")
Call OpenDB()
SQL_query =" SET NOCOUNT ON" & _
" set DateFormat dmy" & _
" declare @FAddress varchar(100)" & _
" set @FAddress='"& FAddress &"'" & _
" set @FAddress=(replace(@FAddress,'%%',''''))" & _........and so on
Is there a better way? Some problems from this is if I am inserting large info in a text datatype, I can't do it.....
Some code or function that I can call and apply to my entire system without recoding alot....:)
SQL and ASP jedi masters...please enlighten me.

This works EXCEPT when I add the ELSE line.
How do I accomplish the ELSE?
Does the ELSE have to state "WHEN [BG_STATUS] <> 'Blocked' and [BG_STATUS] <> 'Closed', etc? Do I have to delineate for the ELSE statement everything that BG_STATUS is *not* equal to? Seems there ought to be a way but I can't find it.
SELECT BG_SEVERITY AS 'Severity',
SUM(CASE WHEN [BG_STATUS] = 'Blocked' THEN 1 ELSE 0 END) as 'Blocked',
SUM(CASE WHEN [BG_STATUS] = 'Closed' THEN 1 ELSE 0 END) as 'Closed',
SUM(CASE WHEN [BG_STATUS] = 'Customer Test' THEN 1 ELSE 0 END) as 'Customer Test',
SUM(CASE WHEN [BG_STATUS] = 'Deferred' THEN 1 ELSE 0 END) as 'Deferred',
