Incorrect Column Expression With CHAR In MS Query
Jan 16, 2014
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”

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.

Hello,
I have to build dynamic sql statement in an SQL task.
The SQL statement is way over 4000 char.
The expression builder complains the length of the expression.
Any work around to this limitation?
Thanks a lot!

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.

Hi All,
I put a blank or 0 in one of column of a text file and then I used BCP to load this file to a table of SQL server 6.5. The field in SQL server table is char type with size 1. After I run this process, all rows with this column received 0 and no blank or null at a black value place. Could you please help me to fix this problem and make some of rows in the column get a blank or null value.
TIA.

i'm going nuts with this, i suppose i will crack it eventually, but i thought i'd ask around here, seems like all the smart SQL Server guys hang out here
(i'm an SQL guy, not an SQL Server guy)
how does one place 5 spaces into a CHAR(5) column?
create table testzeros
( id smallint not null primary key identity
, myfield char(5)
)
insert into testzeros (myfield) values (' 1')
insert into testzeros (myfield) values (' 11')
insert into testzeros (myfield) values (' 111')
insert into testzeros (myfield) values (' 1111')
insert into testzeros (myfield) values ('11111')
insert into testzeros (myfield) values (' ')
select id
, myfield
, len(myfield) as L
from testzerosno matter what i do, id=6 shows up with L=0, just like an empty string
i've even tried inserting 4 spaces and a non-blank character, which enters just fine, just as you would expect, but when i update the value and replace the non-blank character with a blank, all 5 spaces collapse back to an empty string
is there some kind of server setting like SET ALL_SPACE_EQUALS_EMPTY_YOU_IDIOT to OFF or something?

I have a column in my db which is char(40).
There are entries in this with the same text, but some come up with a length of 24 and some 25. This sugggests to me that there is a blank trailing space. Am I right?
However, if I update it to iteslf using a Rtrim, nothing changes.
Is is something to do with ANSI padding?
How can I get these entries to be identical, please?

I have a char(11) for SSN, and I would like to default it to123-45-6789 so I can avoid having nulls in this column, and so I caneasily find the rows in which I need to have a 'correct' SSNentered/updated.I tried using just 123-45-6789, and SQL2005 doesn't seem to bedefaulting to this value, it seems to be keeping it as(((123)-(45))-(6789), and not placing it into this column when a newrow is created....Is there some special way I must specify defaults for a char(11) field(Yes, I will include the dashes).Thank you,Tom

Hi Gents,
I have a file that contains internet addresses accessed by users.

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

Hi I have a table, which contains Char and NChar NOT NULL columns
Now I need to change it to NULL, when I use the following command, it fails for the following error,
The command I used,
ALTER TABLE <TableName>
ALTER COLUMN <ColName> CHAR NULL
ALTER TABLE <TableName>
ALTER COLUMN <ColName> NCHAR NULL
Msg 8152, Level 16, State 13, Line 1
String or binary data would be truncated.
The statement has been terminated.
But for the same table, the below command executes fine,
ALTER TABLE <TableName>
ALTER COLUMN <ColName> SMALLINT NULL
Also I can change the NULLABILITY from NOTNULL to NULL using Enterprise Manger, editing the table using Table Design and selecting Allow Nulls option.
I need a script to accomplish this task.
Any help would be greatly appreciated.

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.

Hi guys/ladies I'm still having some trouble formatting a select statement correctly.
I am using a sqldatasource control on an aspx page. It is connecting via odbc string to an Informix database.
Here is my select statement cut down to the most basic elements.
SELECT commentFROM informix.ipr_stucomWHERE (comment > 70)
The column "comment" contains student grades ranging from 0-100 and the letters I, EE, P, F, etc. Therefore the column is of a char type. This is a problem because I cannot run the above statement without hitting an alpha record and getting the following error
"Character to numeric conversion error"
How can I write this statement where it will work in the datasource control and have it only look at numeric values and skip the alpha values?
I have tried case with cast and isnumeric... I don't think that I have the formating correct.
I have also used:
WHERE (NOT (comment = ' I' OR comment = ' EE' OR comment = ' NG' OR comment = ' WP' OR comment = ' WF' OR comment = ' P' OR comment = ' F'))
This works but is very clunky and could possibly break if other letters are input in the future. There has to be a better way.I am sorry for my ignorance and thanks again for your help.

Is there a way to extract the date part (11/27/2012) of a datetime/time stamp column (11/27/2012 00:00:00.000) and keep it in a date format?
The code i have below extracts the date part of a timestamp column and converts it to a char field. This becomes a problem when I joing the resultant table with a SAS dataset which contains the same column but is in a date format. The join process generates an error saying the column is in different formats.

}
==========================================================
where the job_type columIn is of the char(1) type, NTBSTRINGBIND is the vartype argument in the dbbind() function.
However, what I have gotten is nothing more than a null string from the job_type column. I have alternatively changed the vartype argument to STRINGBIND, CHARBIND and even INTBIND, but the results are the same.
Who can tell me the tricks to retrieve a char(1) column from SQL server?

I have been working on a pretty ugly stored procedure recently, while debugging I added a char(10) to the end of each line of the SQL query so I could copy it to query analyzer(QA) and debug the SQL syntax output from of the stored procedure.
It had no effect on the stored procedure working, but when I copied the query to QA it got the error below, so I removed them all and added them in one line at a time to find the problem.
--Server: Msg 170, Level 15, State 1, Line 3
--Line 3: Incorrect syntax near ','.
Below are the 2 querys, the only difference is the Char(10) between Amt6 and Amt7!
http://www.rakbiz.com/download/broken.txt
http://www.rakbiz.com/download/working.txt
I also tried char(13) with same results.
any ideas why this is happening or how to add line breaks for readability without this problem?
Thanks for your help!

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?
