I am getting a error message saying: Invalid operator for data type. Operator equals boolean AND, type equals datetime.
I traced the pointer to @gdo and @gd, they are both dates!
INSERT INTO AdminAlerts values (CURRENT_USER, 'UPDATE', getDate(), @biui, 'Updated booking, ID of booking updated: ' & @biui & ', Booking date and time before/after update: ' & @gdo & '/' & @gd & ', Room number before/after update: ' & @rno & '/' & @rn & ' and Customer ID before/after update: ' & @cio & '/' & @ci)
If I cut that two dates out it works fine.
Could someone tell me the syntax to include a date in a string :confused:
why following happens? can anyone explain the logic?
if 'a ' = 'a'
select 'equal'
else
select 'not equal'
--------
result: equal
I have a table called "Inc_Exp_Accounts". The table has ledger account numbers and names. It also has a third column called "IsExpense". The IsExpense column is a bit field = 0 (false) if the account is an income account and = -1 (true) if the account is an expense account. I only have income and expense accounts. I do not have other accounts such as asset accounts. The distinguishing thing about income accounts is that the account number (an nvarchar(11) type) is a '3'. Anything else makes it an expense account.
I would think I can use the following SQL statement to correctly set the IsExpense column:
UPDATE Inc_Exp_Accounts
SET IsExpense = IIF(LEFT(Account_Number, 1) = '3', False, True)
But nooo, I cannot! I cannot even run it because Visual Studio SQL Syntax checker rejects it. It complains about the second '='. If I change the second '=' to '>', then it complains about '>'. Therefore, I think I have the particular character about which it complains.
Ths specific complaint (error message) is: "Error in list of function arguments: '=' not recognized.
Unable to parse query text.".
So what is wrong?
Is it possible to use wildcards with an equals statement? Such asSELECT * FROM Table WHERE City = '%' AND State='Ca'Bascially just stating where city equals anything...I know you can do it with a LIKE statement such as...SELECT * FROM Table WHERE City LIKE '%' AND State='Ca'but is that very efficient?The reason I want to do this is because I want to programmitcally set the city, so just ommiting it won't work
Also, using City LIKE '%' seems to not include NULL...is there anywayto include NULL as well as anything else?
Thanks for your help!
Hello,
I perform queries on tables with 500,000 plus records, when I use the like clause or the = for record names with large numbers I get different counts with each run. As an example if I was searching retail stores and k-mart was one I get counts like the following
1st run: k-mart 2200
2nd run: k-mart 2240
3rd run: k-mart 2197 etc. etc.
The records may be k-mart inc or kmart inc or k-mart etc.
If anyone has a better understanding of how the items are searched for and knows a better way please respond.
Thank you in advance.
Hi,
How do I round when number is ending with 5 for example:
When the number next to number 5 is an even number
24.5 = 24.0 round down
0.245 = .24 round down
1265 = 1260 round down
when the number next to number 5 is an odd number
23.5 = 24.0 round up
0.235 = .24 round up
1755 = 1760 round up
Thanks in advance!
I have a table with a column of type date. I want to select all records where the date column = today. I tried
Select * from myTable where DateSent = GetDate()
but it returns no records.
Do I really have to use this slow method?
select datesent from Messages where convert(varchar,DateSent,103) = CONVERT(varchar, GetDate(), 103)
This seems to be a rather old problem (http://www.themssforum.com/SQLServer/Does-empty/) but I couldn't find an answer yet.
The problem is: I have two tables t1 and t2 where t1 is a staging area of t2.
t1: (id int not null, phone varchar(30))
t2: (id int not null, phone varchar(30))
Data in t1: (1, '') <- empty string
Data in t2: (1, ' ') <- a blank
Comparing t1.phone with t2.phone results in equality which in my opinion isn't correct.
The question ist: How can I change the behaviour of SQL-Server to result in inequality so that the change in my staging table is detected correctly?
Thanks in advance

Hello,I currently have Table1 and View1.View1 is a query from 2 or 3 tables that works fine on its own.However in my current query if I try to use it...something like...SELECT a.col1, a.col2, a.col3, b.col1, b.col2, b.col3FROM View1 a JOIN Table1 b on a.col1 = b.col1WHERE a.col2 <b.col2 OR a.col3 <b.col3It throws an error "Server: Msg 446, Level 16, State 9, Line 1 Cannotresolve collation conflict for not equal to operation."Clearly I need to use collation between Table1 and View1, But I dontknow where I need to use "COLLATE SQL_Latin1_General_CP850_CI_AI" andhow? this is the collation set on Table1.Thank you!Yas
View 1 Replies View RelatedUsing this IIF statement:

Why the different dates
Hi,
I get this error dialog when I try to open all the rows of any table from Enterprise manager..
Any help would be really appreciated..
Thanks,
-Srini.
SQL Server 2005 9.0.3161 on Win 2k3 R2
I receive the following error:
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).

I'm trying to find the command to open up an odbc conection inside sql2005 express. I only have ues of an odbc connector, we're conection to remedy. We will eventually be using stored procedures to extract the data we need from remedy and doing additional data crunching. I'm a foxpro programmer so once I get the correct syntax for making the odbc connector I shold be ok. Also I need a really good advanced book on sql2005. The type of book that would have my odbc answer. I've spent all morning trying to find this information and was unable to.
Thanks in advance

We have a issue with a MDS server that have been over us for a couple of days, the original error msg from SQL Server Engine is the one "The query processor could not produce a query plan" but the ones we get on the Excel-Addin are "Sequece contains no elements" or "The value cannot be null" T

how do I get the variables in the cursor, set statement, to NOT update the temp table with the value of the variable ? I want it to pull a date, not the column name stored in the variable...
create table #temptable (columname varchar(150), columnheader varchar(150), earliestdate varchar(120), mostrecentdate varchar(120))
insert into #temptable
SELECT ColumnName, headername, '', '' FROM eddsdbo.[ArtifactViewField] WHERE ItemListType = 'DateTime' AND ArtifactTypeID = 10
--column name
declare @cname varchar(30)
[code]...
-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!!
-- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"
set nocount on
go
if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1
if object_id('tempdb.dbo
[code]....
This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?
Hello everybody,
I'm developing a report using the following structure :

set @where = 'some where'
end
If <conditional2>

set @where = 'some where'
end
set @sql = @sql + @where

I run it in query analyser and works fine, but when I try to run in Reporting Services, Visual studio stops responding and the cpu reaches 100 %.
I realize that when I cut off the if clauses, then it works at Reporting services.
Does anybody know what is happening?
Why the query works in query analyser and doesn't work in Reporting Service ?
Thanks,
Maurício

For each customer, I want to add all of their telephone numbers to a different column. That is, multiple columns (depending on the number of telephone numbers) for each customer/row. How can I achieve that?
I want my output to be
CUSTOMER ID, FIRST NAME, LAST NAME, TEL1, TEL2, TEL3, ... etc
Each 'Tel' will relate to a one or more records in the PHONES table that is linked back to the customer.
I want to do it using SELECT. Is it possible?
do i need to nest a query in RS if i want a calculated column to be compared against a multi value variable? It looks like coding WHERE calcd name in (@variable) violates SQL syntax. My select looked like

FROM...
WHERE ... and calcd name in (@variable)
When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?

I executed the code successfully and I got a box which asked for "Enter the query string".
I typed in the following: EXEC dbo.SalesByCategory @Seafood. I got the following box: Query attempt failed. Must declare the scalar variable "@Seafood". I am learning how to enter the string for the "SQL query programed in the subQuery_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnQuery.Click" (see the code statements listed above). Please help and tell me what I missed and what I should put into the query string to get the information of the "Seafood" category out.
Thanks in advance,

I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included) INSERT INTO @users SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is: SELECT u.userName,u.userID
FROM tableU u
LEFT JOIN tableW w ON w.workgroupID = u.workgroupID
WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!
When I run the following query from Query Analyzer in SQL Serer 2005, I get a message back that says.
Command(s) completed successfully.
What I really need it to do is to display the results of the query. Does anyone know how to do this?
declare @SniierId as uniqueidentifierset @SniierId = '85555560-AD5D-430C-9B97-FB0AC3C7DA1F'declare @SniierAlias as nvarchar(50)declare @AlwaysShowEditButton as bitdeclare @SniierName as nvarchar (128)/* Check access for Sniier */SELECT TOP 1 @SniierName = Sniiers.SniierName, @SniierAlias = Sniiers.SniierAlias, @AlwaysShowEditButton = Sniiers.AlwaysShowEditButtonFROM SniiersWHERE Sniiers.SniierId=@SniierId
I am trying to run queries against any of the user tables in my MS SQL 7.0 database. I get a message the Query Designer encountered a query error.
We have tried rebooting the SQL Server and I am still getting these messages. Also, the SQL error logs look fine - all database
maintenance are running successfully including the DBCCs which show no errors. Any help would be greatly appreciated as we are to go
into production in a few days.
