How SQL calculates the estimated row count when < or > are used in the WHERE clause of a statement. For example:-
WHERE Created_Datetime_utc > CONVERT(DATETIME,'2014-10-14 10:00:00',102)
I know how the estimated number of rows are calculated when an = is used but I've been googling and cannot find anything about < and >.
How I am using a CASE statement within a WHERE clause to filter data:
CREATE PROCEDURE dbo.GetSomeStuff
@filter1 varchar(100) = '',
@filter2 varchar(100) = ''
AS
BEGIN
SELECT
[Code] .
What I want, is to be able to pass in a single value to filter the table, or if I pass in (at the moment a blank) for no filter to be applied to the table.
Is this a good way to accomplish that, or is there a better way? Also, down the line I'm probably going to want to have multiple filter items for a single filter, what would be the best way to implement that?
I have a two tables each having a uniqueidentifier column person_id
I am trying to a select statement where I want a list of the person_id's in one table that are not in another table.
-- insert into wch_needed those who need checked
insert into #wch_needed (person_id, rendered_by )
select distinct e.person_id, e.rendered_by
from #wch_who o, encounter e
where o.person_id not in (select distinct person_id from #wch_have )
and o.person_id = e.person_id
the where conditional
where o.person_id not in (select distinct person_id from #wch_have )
does not work.
How can I do this?
My table structure like below.

My client's website database is hosted by a third party. I need to alter one of the column definitions for the largest table in the database. Unfortunately, the transaction log fills up if I try to alter the table. I've done all the usual stuff like truncating the log, etc., but the simple fact is that the operation requires more log space than we have available. Therefore, we need to purchase additional disk space for the database.
What I'm looking for is a way to roughly estimate how much log space will be required to alter this table so that we purchase enough but not too much additional space. The table has an identity primary key and 4 other single column indexes: one int, one datetime and two varchar(30) columns.
Any suggestions? Thanks in advance.
I was having interesting discussion on estimation of log file with a fellow collegue who happens to be quite knowledgable as well.
He told me if we identify the most frequently hit tables for a database and then (sum their sizes * 1.5) for OLAP we get rough estimate for disk space to be allocated for log file.
I have a table like below,
CREATE TABLE Student
(
Id BIGINT not null
,Name NCHAR(20) not Null
,Branch NVARCHAR (64) null
)
The table contains : 100000 rows .
Getting details of below
1)Number of rows in a data page
2)Total number of pages required for the table
3)Total Table size in KB or MB
4)Total file size in Kb or MB
I am selecting the count of the students in a class by suing select COUNT(studentid) as StCount FROM dbo.student But I need to use a case statement on this like if count is less than 10 I need to return 'Small class' if the count is between 10 to 50 then I need to return 'Medium class' and if the count is more than 50 then 'Big class'.
Right now I am achieving this by the following case statement
SELECT 'ClassSize' = CASE WHEN Stcount<10 THEN 'Small Class'
WHEN Stcount>=10 and StCount<=50THEN 'Medium Class'
WHEN Stcount>50 THEN 'Big Class'
END
FROM(
select COUNT(studentid) as Stcount FROM dbo.student) Stdtbl
But can I do this with just one select statement?

I have the following query where I select records from Active_Activities_temp which do not match on cde_actv in the table ACTIVITY_CORE_LISTING:
SELECT Active_Activities_temp.*
FROM Active_Activities_temp LEFT JOIN
ACTIVITY_CORE_LISTING ON
Active_Activities_temp.cde_actv=ACTIVITY_CORE_LISTING.cde_actv
WHEREACTIVITY_CORE_LISTING.cde_actv is null
ORDER BY prtcpnt_id
So for example, if a participant has a cde_actv=38 (which doesn't exist in ACTIVITY_CORE_LISTING), that record would appear as the query is currently.
The issue is that participants can have multiple records in Active_Activities_temp and if a participant has a record that does exist in ACTIVITY_CORE_LISTING, no records for that participant should appear in this query result. For example, if a participant has two records in Active_Activities_temp, one with a cde_actv 38 (which does not appear in ACTIVITY_CORE_LISTING) and one with a cde_actv 33 (which does appear in ACTIVITY_CORE_LISTING), no records for that participant should appear in the result. Currently the record with cde_actv=38 does appear.
What code can I implement to do what I need to do? Thanks so much.
I have an autogenerated MDX.
Select

As a result I only get 29 records. One record in the middle is missing. If I change to Topcount 31 I get 32 records, where the missing record is also included.
If I remove the Zero supression I receive 30 records as expected. For me the MDX looks good. I will try to reproduce on AW.
Arvind writes "i want to create a stored procedure returns an OUTPUT variable containing the no. of records given by a query, the query being dynamic.
Preferrably the query should also be passed as a parameter to the stored procedure...If not,it should be constructed in the SP and a Part of the where clause is dependant on the value of another variable passed to the SP.
How should the query be constructed, executed, and then the Count(*) value returned?

I am trying to write sql to basically say if c.rel_value IN ('XYZ','ABC') then rel_attr_id = 'A0' else rel_attr_id = 'C1'...bbut to get the rel_value we need the rel_attr_id to be 'A0' to begin with....so my statement currently is...
select c.client, c.attribute_id, b.dim_value, a.description, c.rel_attr_id, c.rel_value, 'N' as status
from agldescription a, agldimvalue b, aglrelvalue c
where b.client = c.client AND b.attribute_id = c.attribute_id AND

a.client = b.client AND a.attribute_id = b.attribute_id AND
a.dim_value = b.dim_value AND a.language = 'EN' AND
a.attribute_id = '70' AND c.rel_attr_id = 'A0'
then I want to say as per above but if the rel_value are in XYZ or ABC then sqap rel_attr_id to 'C1' otherwise keep with 'A0'...
Can the like clause be used in IF statement or only applicable to SELECT statement ?
e.g.
IF (@lADDRESS LIKE '%P.O. BOX')
BEGIN
PRINT 'IGNORE ADDRESS'
END

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
I need a SQL statement that selects a specific year (@yr type int) in the "createddate" column...if this @yr is equal to 0 then I want to select ALL columns regardless of the year...This is what I have so far, but it doesnt work...SELECT * FROM tblUsersWHERE year(CreatedDate)=CASEWHEN @yr<>'0' THEN @yrELSE NOT NULLEND

Hi,
I need help to use CASE Statement within my WHERE Clause. I want to change the WHERE Clause based on my condition as following:
SELECT ...
FROM ...
WHERE (condition)
AND (condition)
AND (condition)
AND (
CASE Table.Category
WHEN 'Drinks' THEN
Table1.Field1 = 1 -- Problem line
ELSE
Table1.Field1 = 1 AND Table1.Field2 = 1 -- Problem line
END
)
In the above case, my WHERE Clause is dependent on one of the fields in a table. If it has a certain value then only Table1.Field1 is used otherwise Table1.Field1 & Field2 come into action.
I am getting error on the mentioned line (Problem Line). Since CASE is an expression and does not execute a statement, can anyone help me to get my WHERE Clause working...
Thanks in advance...
I have a column in the database that stored moduleId that are seperated by '|' (pipes). For Example: '527|343|454'

Does anyone know how I can do this in a query? Normally I could
use an IN statement, ex: select * from table where 527 in (527,343,454)
How can I get the column in that format?

can i use case in where clause so that if @param is '' then i will not include in the where clause
Can I do the following? Keep getting an error stopping at the first < of the where clause.

i have wrote a query which compares two tables, returning anywhere the qty is not the same in each table:
(simple ex)
Select order_no
from table1
inner join table2
on table1.order_no = table2.order_no
group by order_no
having table1.Qty<> table2.Qty
BUT... I need to add a table3, where there maybe (or may not be enters - thus a left join). If there is an entry in table3 then use qty in table3 and not table1... so having becomes:
CASE WHEN table1.Qty<> table3.Qty
THEN table3.Qty<> table2.Qty
ELSE table1.Qty<> table2.Qty END
but how do i actually write this?
