Cannot Check Column In Where Clause
Apr 8, 2004
In a stored procedure I have I have dates in the format YYYYMMDD with symbols representing the first 3 digits
e.g. °30903 =20030903, and I have to convert them to proper dates, and then eliminate all old data, so I replace symbols and then convert to int
SELECT af.AccomType, af.AccomRef, af.AccomName,af.address1, af.address2, bf1.RoomCode,
Convert(Int,Replace(Replace(Replace(Replace(REPLAC E(Replace(MAX(bf1.EndBook),'°','200'),'´','204'),' 99','1999'),'97','1997'),'47',1947),'98','1998')) AS max_date,
...............
WHERE
af.Resort=@strResort
AND
(af.AccomType = 'H' OR af.AccomType = 'O')
AND
max_date>20040721
order by max_date.
Problem is I get an error saying invalid column max_date. It works in the order by clause when I get rid of the
'max_date>20040721 '.
Thanks

Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave

2 examples:
1) Rows ordered using textual id rather than numeric id
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id
Result set is ordered as: 1, 11, 2
I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16
A column has been specified more than once in the order by list. Columns in the order by list must be unique.
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
cross join (
select 1 id
union select 2 id
union select 11 id
) u
order by
v.id
,u.id
Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
It reproducible on
Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
and
Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Feb 9 2007 22:47:07 Copyright (c) 1988-2005 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
In both cases database collation is SQL_Latin1_General_CP1251_CS_AS
If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.
Could someone clarify - is it bug or expected behaviour?

I have two columns.
policyNumber contains a 12-13 varchar string
AllPolicyNumbersIncluded contains one or more 12-13 varchar strings (policy nums) seperated by commas
I want to check if policyNumber is contained in AllPolicyNumbersIncluded?
I have policyNumber LIKE AllPolicyNumbersIncluded which works when only one policy number is in AllPolicyNumbersIncluded and incidently works switched around AllPolicyNumbersIncluded LIKE policyNumber I assume because they are equal.
Can anyone tell me how to check if one column's value is a substring of another - without going through every possible substring of the second

In a SPROC I am creating, is there a way to use a columnName as a parameter and then do a filter on that based on a second parameter such as @columnValue ?
So instead of having to construct the WHERE clause or doing a bunch of IF statements to see what the column name is from the parameter and doing a query based upon that, is there a way to tell it to do a WHERE clause where @columnName = @columnValue ?
I do not want to use dynamic SQL string concatenation...

Hi,
I have a [TestTable] table with three rows. The pair of columns [Test1] and [Test2] are id, the [Test3] is a data column. First, I get a table variable with list of id pairs. Next, I would like to update the rows of that ids. However, I have not found the elegant way how to do it. For one column it is simple, just IN clause, which does not work (or I could not find how) for multi-columns. Does someone have a hint?
Thanks,
Martin
Note: The example bellow is dummy; on the other hand, I hope it shows the important points. Please, do not beat me on syntax errors.
Code Block
DECLARE @MyTableVar table(
Test1 int NOT NULL,
Test2 int NOT NULL
);
SELECT [Test1],[Test2] INTO @MyTableVar FROM [TestTable] WHERE [Test3] = '%dd%';
UPDATE [TestTable] SET [Test3] = [Test3] + 'ds'
WHERE ([Test1], [Test2]) IN (SELECT [Test1], [Test2] FROM @MyTableVar);

Can't seem to get my head around this: I'm looking for a way to select only those varchar(10) values that soley consist of numbers. Leading spaces are allowed.
I tried using isnumeric, but it also allows those with periods, comma's etc.
Also tried using like, but the length of the varchar column varies too much to do a like '[0-9][0-9]....'.
As a solution I currently do a combo of isnumeric, not like '%.%', not like '%,%' etc. I need to do a conversion to an int to join another table, but the convert still fails. Not sure where and why.
I'm thinking there should be a better way than create a hughe list of "not like " but it looks like I'm in the woods here...

I am trying to query multiple columns for a specific value. I have 8 columns (values are either 1 or 0)and I want to query the table to find out which rows contain zero's in ALL of the 8 columns. Whats the best way to do this? I can create a lenghty select statement where column1 =0 and column2 =0 and column3=0 and column4 =0 and column5 =0 .... etc. I was wondering if there was an easier way to do this?
Thanks in Advance

Can you tell me if this is possible? (and how to do it!!)
The application is VS2005, with sql database.
I want to check if a specific column exists in a specific table in the database and if not then add it, all via my application.
I'm happy knowing how to connect to the database & pass sql commands (as I'm doing that anyway to set off backups), but not the actual queries I'd need.

Well, actually, as in the title. I have a table. The script should add a column if that column doesn't exist already. I use VB to combine the two queries. So what I want:
Query1: Does the column exists:
if No,
query2: create the column
How can I achieve this?

Hi
I need suggestion for a query. Consider following 2 tables.
Table-1 "T1"
-----------
|ID|Name
|1 |abc
|2 |def
|3 |erw
|4 |rwg
|5 |her
Table-2 "T2"
----------
|ID|Qty
|1 |12
|1 |2
|2 |22
|3 |10
|2 |14
I want a query which displays ID, Name and MAX(Qty) for each item where Max(Qty)>=10 i.e. result should be
Result
----------
|ID|Name|Qty
|1 |abc |12
|2 |def |22
|3 |erw |10
I tried:
Select t1.*, (Select Max(Qty) From T2 where ID=t1.ID) as MaxQty
FROM T1 t1
WHERE MaxQty>=10
But it fails as computed or inline query columns can not be added in where clause.
However following works:
Select t1.*, (Select Max(Qty) From T2 where ID=t1.ID) as MaxQty
FROM T1 t1
WHERE (Select Max(Qty) From T2 where ID=t1.ID) >=10
BUT IS IT OPTIMIZED?
Please suggest an optimized way to handle such scenarios.

Hello, I am using the JDCB-ODBC driver for my app, but one of the columns in my WHERE clause is 255 characters long. Because of this no rows are returned even though the statement should return 1 or 2 rows. I've tried other JDBC-ODBC drivers too and they have the same problem. Additionally, I've tried using RTrim(), Substring(), etc and it still will not work....any ideas? Is it a driver bug? Anyone know of a driver that will work?
Sample code....
ResultSet rs = dbRetrieve.getStatement().executeQuery( sql ) ;
if (rs.next()) {
// Never gets here
}
Thanx!

I am busy extending a VB6 app to talk to SQL Server Express 2005 and have come across a naming conflict. Some of the columns in the application's Access 97 tables is "index" which obviously exists as a T-SQL keyword and therefore any queries I perform including this column throws a syntax error. I tried prefixing the columns with their table names as in TableName.Index, but this still throws up the syntax error which I thought was a bit odd. I preferably want a fix that will be Access as well as T-SQL compliant but if that's not possible I will just write a string converter that does the job based on anyone's suggestions. TIA

Hi all,
I'd think this is possible but I'm having trouble getting data returned from the query. Fields PART_NUMBER and INTERNAL_SKU exist in the SKU table. This will be inside a SP. If user passes 'PN' as first parameter then I'd need to have the WHERE clause by PART_NUMBER, if he passes 'SK' (or anything else for now) then the WHERE clause shold be by SKU.
Can't I just build the WHERE by replacing @SearchField with its value ? I've looked up the CASE statement but I don't think it does what I need.
DECLARE @strSearchType varchar(2)
DECLARE @strSearchValue varchar(15)
DECLARE @SearchField varchar(15)
set @strSearchType = 'PN'
set @strSearchValue = '1234567'
IF @strSearchType = 'PN'
begin
set @SearchField = 'PART_NUMBER'
end
ELSE
begin
set @SearchField = 'INTERNAL_SKU'
end
SELECT
SKU as 'SKU',
PART_NUMBER as 'PartNumber',
DESCRIPTION as 'Description'
FROM SKUs
WHERE @SearchField = @strSearchValue
FOR XML PATH('SKU'), ROOT('Response')
Thanks,

say i have a table, and in it are two columns, column1 and column2 and i do the following query:
SELECT column1, column2 FROM table WHERE column2 = '12345'
i want to check if column1 has all the same values, so in the first case, no
column1 column2
------- --------
4 12345
9 12345
5 12345
column1 column2
------- --------
9 12345
9 12345
9 12345
in the 2nd case, column1 contains all the same values, so yes
is there anyway i can check this? i would be doing this in a trigger.. say when a new row is inserted, the value of column1 is inserted, but col 2 is null.. so when they try to fill in the value for col2 of that row, the trigger checks to see if the value they put for col 2 is already in the table.. if it isn't, then everything is ok. but if it is already in teh table, then it checks col1 to see if all the values of col1 are the same
i hope this makes sense
thanks

Hi All,
We have a very convoluted ETL system which is pulling unnecessary data. First thought is to restrict everything so that only the columns/tables that are necessary are brought back. We have a tons of reporting stored procedures that depend on ETL tables, is there anyway we can find out which column/tables these stored procedures are using?
Thanks!

How to check to make sure a column does not exist before adding it? Be nice to do this in t-sql code instead of using ado.net. It seems as if the IF NOT EXISTS is not supported in SqlCe 3.1? I am trying to do this but I get the token error:
IF NOT EXISTS (
select *
from Information_SCHEMA.columns
where Table_name='authors' and column_name='NewColumn'
)
select 'no'
Is there a list of all CE supported t-sql commands?
Thanks,

When generating a check constraint to guarantee that a character column cannot be blank is it best to use comparison operators such as col1 <> '' or to use LEN(col1) > 0? Note that the column in marked as not nullable.

1. Col2,3,4 are NULL
WHERE Col1 = condition
2. Col2 is NULL, 3 may or may not be NULL. When Col3 is NOT NULL, Col4 may or may not be NULL
where col1 and (col3(Not Null values) OR Col4(Not Null values)) = condition.
How do I construct this logic. Please help
