Ms Query Sql Error 'Incorrect Column Expression'
Jul 22, 2005
I am getting an error from the case part of the select statement below which reads 'Incorrect Column Expression' then it quotes the case statement. All I am trying to do is convert and return the weight value to kilos if it was entered in pounds.
SELECT Salesinv.Unique, Salesinv.SalesNo, Salesinv.PurchNo, Salesinv.SalesInvNo, Salesinv.InvValue,
(case when Salesinv.WUnits = 'Llb' then round(Salesinv.NettWeight/2.2046,0) else Salesinv.NettWeight end)
FROM Salesinv Salesinv
WHERE (Salesinv.Unique>=38397.3092 And Salesinv.Unique<=38537.39885)
Any help would be greatly appreciated, hopefully thanks in advance.

I am working with Excel, then within Excel I am using MS Query to query a database. I am trying to use the CAST function on a field with numbers (1,2 or 3 digits) so I can convert it to a text value with three digits, i.e. 1 would read 001, 12 would read 012, etc.
I am not using CAST in the design grid. Is this even possible?
I am modifying the underlying SQL code. Here is the line that is giving me trouble:
CAST(GL02GLF.GLF_SEQ_NUM as CHAR(3)) as “Sequence”

Hi all,
I use
="<Query><XmlData>" & Parameters!XMLData.Value & "</XmlData><ElementPath>Product {@}</ElementPath></Query>"
and I enter XMLData with value "<Products><Product>Chair</Product><Product>Table</Product></Products>"
for the query expression of the dataset, and I always got error:
Query failed for dataset "Dataset1"
Incorrect syntax near '<'
What's wrong with it?
Thanks,
Jone

I'm getting the error listed above. To create this I used the wizard in VS2005 for the datagrid. The delete works but not the updating. I can't seem to find what's wrong. In the update parameters I've removed eventID and added it, neither works. Delete does work. Here's the code:

I ran this query against the pubs database and it runs successfully
ALTER TABLE publishers ALTER COLUMN state CHAR(25)
I change the table & field names for my db as follows:
ALTER TABLE customquery ALTER COLUMN toclause CHAR(25)
and run against my database and I get the following error - Incorrect syntax near 'COLUMN'.
My column name is correct - I don't know why it would run fine against pubs, but not my db. I do not have quoted identifiers turned on. I have tried using [] around my column name [toclause], but that didn't change anything. Any help would be appreciated.
Thanks.

I've imported a number of excel sheets into a Power Query Table. All seems to appear ok until I load the data. Of the 15k rows around 2k have a similar error where it cannot convert an integer to type string as below example
Expression.Error: We cannot convert the value 40 to type Text.
Details:
Value=40
Type=Type
The columns in question are all of integer type, I've looked through the M query and there is no conversion to string taking placeThe values where we don't get the error are also integers hence the intriguing question is why does the error occur on a subset and not the others. I suspect there is a limit to the number of errors also somewhere internally M query is converting the column to text for some reason.

Hi, how are you?
I'm having a problem and I don't know if it can be solved with a derived column expression. This is the problem:
We are looking data in a a sql database.
We are writting the SQL result in a flat file.
We need to transform data in one of the columns.
For example: we can have 3 digits as value in a column but that column must be 10 digit length. So we have to complete all the missing digits with a zero. So, that column will have the original 3 digits and 7 zeros. How we can do that tranformation? We must do it from de the flat file or it can be a previous step?
Thanks for any help you can give me.
Regards,
Beli

I have a table with a column in it called Date, which is of the type DateTime, and for the last two years I have been adding data which I found out was incorrect.
My dates are all a day in the future, so I need to reduce each date by one day.
I can easily use a select script to reveal the 25,000 rows which are all incorrect dates. But I can't figure out how to update each and every row to subtract one day from each date.
So where I have:
26/01/2005
I would like to have:
25/01/2005
and of course for every record. Obviously way too many to do manually :-(
Can anyone show me a script that will get what I'm after.

This works correctly in the Business Intelligence Dev Studio tool and on one of our servers, but fails on the other two servers. The two servers that do not work are current on their patches.
When a matrix has multiple rows and multiple columns, the highest level column subtotal is in the wrong scope. Say we have three row groups (r1, r2, and r3) and two column groups (c1, c2). All five groups have subtotals enabled. We can check the scope of every cell by setting the expression of our Detail/Value textbox like so:
=IIf(InScope("r1"),"r1, ","") &
IIf(InScope("r2"),"r2, ","") &
IIf(InScope("r3"),"r3, ","") &
IIf(InScope("c1"),"c1, ","") &
IIf(InScope("c2"),"c2, ","")
When run, the lowest level "detail" boxes should be in the scope of all groups: "r1, r2, r3, c1, c2,". The subtotal of r3 is in scope for everything except for itself (r1, r2, c1, c2,), and so on (see "Good server" screenshot).
This is how it should work, and it does work this way in the design tool and our one (development) server. The other two servers (which are, unfortunately, the Test and Production servers) have a problem: the subtotal of c1 (the column running furthest along the right) is ONLY r1. Always. Which results in some ridiculously large subtotals for detail rows.
We've tested this with various combinations of 2 - 5 column groups and 2 - 5 row groups and found no difference; the problem still hits the furthest right column in the exact same way. We've changed everything we can think of, and tried multiple reports built from scratch and using different data sources, but the results are still consistent.
Any ideas, explanations, or suggestions would be much appreciated.

STDEV() gives incorrect values with reasonable input.
I have a table filled with GPS readings. I've got a column LATITUDE (FLOAT) with about 20,000 records between 35.6369018 and 35.639890. (Same value to the first 5 digits of precision---what can i say, it's a good gps.)
Here's what happens when I ask SQL Server ("9.00.1399.06 (IntelX86)") to compute the standard deviation of the latitude:
// Transact-SQL StdDev function:
SELECT STDEV(LATITUDE) FROM GPSHISTORY
WHERE STATTIME BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
0
// Zero. ZERO??!?!!
//Let's re-implement Std Dev from the definition using other aggregate functions:
DECLARE @AVERAGE FLOAT;
SELECT @AVERAGE = AVG(LATITUDE) FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
SELECT SQRT(SUM(SQUARE((LATITUDE - @AVERAGE)))/COUNT(LATITUDE)) FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
6.03401924005392E-06
// That's better. Maybe STDEV is using fixed point arithmetic?!?
SELECT STDEV(10 * LATITUDE)/10 FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
4.77267753808509E-06
SELECT STDEV(100 * LATITUDE)/100 FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
1.66904329068838E-05
SELECT STDEV(1000 * LATITUDE)/1000 FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
8.11904280806654E-06
// The standard deviation should, of course, be linear, e.g.
DECLARE @AVERAGE FLOAT;
SELECT @AVERAGE = AVG(LATITUDE) FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
SELECT SQRT(SUM(SQUARE(100*(LATITUDE - @AVERAGE)))/COUNT(LATITUDE))/100 FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
6.03401924005389E-06
// Std Dev is a numerically stable computation, although it does require traversing the dataset twice.
//
// This calculation is not being done correctly.
//
// Incidently, SQRT(VAR(Latitude....)) gives 4.80354E-4, which is also way off.
I will redefine STDEV to use a stored procedure similar to the above, but the algorithm used to compute VAR, STDEV etc should be reviewed and fixed.

Is the SQL Server Profiler Reads Column Incorrect For Parallel Plans?
I often use profiler as one tool to identify bad plans. The reads column gives me a good indication of excessive IO to dig into and correct if necessary. I often use it with Showplan so I can see what a query does, replicate it and fix it.
However I have just lost some faith in it. I am looking at a poorly performing query joining five tables. A parallel plan has been generated and one table is being scanned (in parallel) due to a missing index. This table had in excess of 4 million rows in it. The rest hitd indexes well. However the entire query generates ONLY 12 READS.
Once corrected, a single processor plan is used. This looks really efficient and uses 120 reads. That looks the right figure to me.
Does the profiler only display one thread of a parallel plan perhaps? Or something else?

I often use profiler as one tool to identify bad plans. The reads column gives me a good indication of excessive IO to dig into and correct if necessary. I often use it with Showplan so I can see what a query does, replicate it and fix it.
However I have just lost some faith in it. I am looking at a poorly performing query joining five tables. A parallel plan has been generated and one table is being scanned (in parallel) due to a missing index. This table had in excess of 4 million rows in it. The rest hitd indexes well. However the entire query generates ONLY 12 READS.
Once corrected, a single processor plan is used. This looks really efficient and uses 120 reads. That looks the right figure to me.
Clearly 12 reads is wrong. Does the profiler only display one thread of a parallel plan perhaps? Or something else?

I'm trying to show a column only if a certain parameter contains a certain string of characters. So far I've got it working if the parameter is equal to the string of characters by doing
=IIF (Parameters!Param1.Value = "String1", False, True)
but I would like it to work if the Param1.Value contains "String1" ... I tried
=IIF (Parameters!Param1.Value like "%String1%", False, True)
but it doesn't work. Any suggestions?
TIA

Hi:
I have a Dervied Column Component, in which there is a column called RecStatusCode. The criteria to give a value to that column is below in SQL:
(SELECT CASE CertParticipant
WHEN 'Y' THEN 'C'
WHEN NULL THEN 'A'
END
FROM [dbo].[SchoolCertRequest]
WHERE SchoolID = (SELECT SchoolCode FROM [WebStrategy].[LAF].[LoanApplication] WHERE LoanApplicationID = @LoanApplicationID) and SchoolBranch = (SELECT BranchCode FROM [WebStrategy].[LAF].[LoanApplication] WHERE LoanApplicationID = @LoanApplicationID) AND LoanType=(SELECT LoanApplicationTypeCode FROM [WebStrategy].[LAF].[LoanApplication] WHERE LoanApplicationID = @LoanApplicationID))
My question is how can I use this SQL in that expression field, or is it possible to have a user variable, with the above sql being the criteria, and the value could be used in the derived column, by just using the variable in the expression. In either case, I hope you understand what I am trying to accomplish. The reason why its like this is because currently in my Data Flow Task, i Have a OLEDB source which returns 25+ column values, the source connects to this derived column item, and then finally the destination oledb where the mapping takes place. So basically I am trying to avoid MERGE JOIN, because i tried using it , and it complicated the whole thing much more then it really needs to be. Like the RecStatusCode column, i have 5 more columns which are dervied, and the values are coming from a SQL statement similar to above. I really need some help here, and I have not seen anything in reference to this in BOL or any articles online. Thanks in advance.

I'm using the following vbScript and T-SQL and receiving a seemingly strange error:

For reference, I have tried changing intUserID to be a different value (e.g. 13) to ensure it is not that '4' in question - likewise for @complete = 24 (e.g. 23).
Any ideas where the 4 is coming from and what is wrong here?

I have this as my query text
SELECT MachNumber, ShiftNumber, HeatNumber, PartNumber,
RevNumber, CureTime, Bump1, Bump1Interval, Bump2,
Bump2Interval, DwellTime, LateToDrop, EarlyToDrop,
OverTime, CycleTime, ChangeTime, Date
FROM HeatInfo
WHERE (ShiftNumber = @ShiftNumber)
AND (Date >= @StartDate) AND (Date <= @EndDate)
This correctly returns 4 rows, which is great except that I would like to have these records Sorted by the Date. So I added the OrderBy command to the bottom of the query, like this
SELECT MachNumber, ShiftNumber, HeatNumber, PartNumber,
RevNumber, CureTime, Bump1, Bump1Interval, Bump2,
Bump2Interval, DwellTime, LateToDrop, EarlyToDrop,
OverTime, CycleTime, ChangeTime, Date
FROM HeatInfo
WHERE (ShiftNumber = @ShiftNumber)
AND (Date >= @StartDate) AND (Date <= @EndDate)
ORDER BY Date
This query returns 181 rows! whis is not great. What am I doing wrong here, I suppose that it is something extreamly obvious or I would probably have figured it out.

I was doing a demo last night, something that I've done hundreds of times already. Last night was the first time that it has failed to work. I was trying to show what the sys.dm_db_missing_index_* DMVs can provide.
AdventureWorks database
I'm running the following query:
select city from person.address where city like 'A%'
This is supposed to produce a table scan which in turn will obviously cause SQL Server to detect that an index could be beneficial. However, it does a clustered index scan (yes, I know, basically the same thing) instead and I see absolutely nothing appear in the DMVs. I pulled the data out into a dummy table that did not have a primary key either using the following:
select * into person.tmpaddress from person.address
I then execute the same query and get a table scan which is expected:
select city from person.address where city like 'A%'
However, it does not matter how much I execute that query or any other permutation of explicit query, absolutely nothing at all gets logged into the sys.dm_db_missing_index_* DMVs. I have also tried this same type of thing with several other tables in the AW database and can not find a single query which will cause anything to be logged to these DMVs. It seems that something is broken, but for the life of me, I can't figure out what is wrong. No weird settings, I'm running as sa, etc.
I can run queries like this in other databases and stuff gets immediately logged to the DMVs as expected. Any ideas?

I have a table in my report which shows sales values for each month by looking at the month number
so for Jan i use
=IIf(Fields!period_.Value=1,Fields!nett_.Value,0)
for Feb
=IIf(Fields!period_.Value=2,Fields!nett_.Value,0)
this is all good and I get a series of rows per customer with the correct value in the correct column
JAN FEB Mar
Customer A 250
Customer A 350
Customer A 5000
.
However I want to create a summary a line
JAN FEB Mar
Customer A 250 350 5000
I tried using SUM but this doesn't give all of the values in the summary line. It might just give the first and the rest are zeros. Or if the customer didn't have a value in Jan, but did in Feb and March, Feb's value is shown, but March is at 0 etc.
Have spent far too long on this today, so if anyone as any suggestion (come back Crystal all is forgiven ) on any approach I could take to this I'd appreciate it.
Cheers
Steven

Hi, all experts here,
Thank you very much for your kind attention.
I am having a question on derived column expression. The expression I am trying to use for the derived column is as below (column1 is a numeric data type column):
case
when column1<0 then 'yes'
else 'no'
end
But I got the error message though, would please any experts here give me any advices on the expression I used? What is wrong with the expression I used above?
Thank you very much and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,

The following simple expression is not working for in a derived column transform. I have tried several things back and forth with lots of frustration.
DAY((DT_DATE)mydate)
In fact any of the date/time functions are not working for me and I keep getting the following error
[Derived Column [380]] Error: The "component "Derived Column" (380)"
failed because error code 0xC0049067 occurred, and the error row
disposition on "output column "Derived Column 1" (824)" specifies
failure on error. An error occurred on the specified object of the specified component.
mydate happens to be imported as string[DT_STR] column from a flat file source.
Thank you in advance.

Hi.
I am using the following expression to check if the first charcter of a string is not the letter "E" and if it is, strip it off by selecting the remainder of the string:
SUBSTRING([Derv.comno],1,1) == "E" ? SUBSTRING([Derv.comno],2,10) : [Derv.comno]
This is ok in 99.9% of cases, but ideally I would like to be able to check, and alter the string if the first charcter is anything but numeric
I had something like this in mind:
SUBSTRING([Derv.comno],1,1) != ("1","2","3") ? SUBSTRING([Derv.comno],2,10) : [Derv.comno]
but the syntax is incorrect.
Could you tell me if what I am attempting is actually possible, and if so, point me in the right direction regarding the syntax!
Thanks
