Sqlcmd to generate file without dashed line under header, without row count - sql-server-2005

Using the following sqlcmd script:
sqlcmd -S . -d MyDb -E -s, -W -Q "select account,rptmonth, thename from theTable"
> c:\dataExport.csv
I get an csv output file containing
acctnum,rptmonth,facilname
-------,--------,---------

ARBO02,201406,Arbors Care Center

Hill
. . .
(139 rows affected)
Is there a way to get rid of the dashed line under the column headers : -------,--------, but keep the column headers?
and also a way to get rid of the two lines used for the row count on the bottom?
I tries using parm -h-1 but that got rid of the column headers as well as the dashed line.

Solutions:
1) To remove the row count ("(139 rows affected)") you should use SET NOCOUNT ON statement. See ref.
2) To remove column headers you should use -h parameter with value -1. See ref (section Formatting Options).
Examples:
C:\Users\sqlservr.exe>sqlcmd -S(local)\SQL2012 -d Test -E -h -1 -s, -W -Q "set nocount on; select * from dbo.Account" > d:\export.txt.
or
C:\Users\sqlservr.exe>sqlcmd -S(local)\SQL2012 -d Test -E -h -1 -s, -W -Q "set nocount on; select * from dbo.Account" -o "d:\export2.txt"

The guy with the top answer didn't answer how to remove the dashed line. This is my awesome solution.
First include -h -1 which removes both the dashed line and header
Then before your select statement manually inject the header string that you need with a PRINT statement. So in your case PRINT 'acctnum,rptmonth,facilname' select..*...from...
Sorry I'm 4 years and 9 months late.

Use the following;
sqlcmd -S . -d MyDb -E -s, -h-1 -W -Q "set nocount on;select 'account','rptmonth', 'thename';select account,rptmonth, thename from theTable"
> c:\dataExport.csv
remove the header -h-1
remove row count [set nocount on;]
add header select [select 'account','rptmonth', 'thename';]
add your select [select account,rptmonth, thename from theTable;]

To remove the Row Count:
Add the below to your SQL statement
SET NOCOUNT ON;
To remove the hyphen row try the following upon successful execution:
findstr /v /c:"---" c:\dataExport.csv > c:\finalExport.csv
I use "---" as all my columns are over 3 characters and I never have that string in my data but you could also use "-,-" to reduce the risk further or any delimiter based on your data in place of the ",".

In my case worked well as :
type Temp.txt | findstr /v -- > DestFile.txt

In addition, if you want to query out all records in a table, you can code as
SET NOCOUNT ON;
SELECT SUBSTRING((SELECT ','+ COLUMN_NAME FROM
INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME=N'%table_name%' FOR XML
PATH('') ), 2, 9999);
SELECT * FROM %table_name%
Assign the above queries into a variable %query%. The the command will be looks like as below.
SQLCMD -h -1 -W -E -S %sql_server% -d %sql_dabase% -Q %query% -s"," -o output_file.csv

This is the one line solution, without doing anything inside the stored procedure to append the column headers:
sqlcmd -S . -d MyDb -E -s, -W -Q "select account,rptmonth, thename from theTable"
| findstr /v /c:"-" /b > "c:\dataExport.csv" & exit 0
What this does is it intercepts all console output and replaces the "-" char BEFORE it redirects to the output file. There is NO need to output to intermediary file. And you will need a one-liner command if you use an agent to run these commands remotely on the sql server machines, which most of the times are locked from hosting *.bat files (which you'd need for multiline commands).
I added the "exit 0" at the end to not fail the caller application overall. You may remove it starting "& exit 0" if you don't care about that.
This one liner is why I chose sqlcmd over bcp out, by the way. BCP, although optimized for speed, cannot output column headers unless doing the ugly trick within the stored proc, to append them there as a union all.
Just in case you have access to writing a bat file that contains this one liner, you MUST add #ECHO OFF before it. Otherwise the console output will also have the actual command.
Hope it helps.

With SQL Server 2017 (14.x) and later you can print header with:
SELECT string_agg(COLUMN_NAME, ', ') within group (order by ORDINAL_POSITION asc) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='YOUR_TABLE_NAME'

1.Create the file first with the header columns
2.Apprend the sqlcmd output to the file using the option -h-1
echo acctnum,rptmonth,facilname > c:\dataExport.csv
sqlcmd -S . -d MyDb -E -s, -h-1 -W -Q "select account,rptmonth, thename from theTable" >> c:\dataExport.csv

I used another solution to solve the issue of removing the dashed line below the header.
DECLARE #combinedString VARCHAR(MAX);
SELECT #combinedString = COALESCE(#combinedString + '|', '') + COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'YOUR_TABLE_NAME'
Then just use
Print #combinedString above your select statement.
I used pipe delimiter.

Using for loop bat file windows for multiple command calls

I want to export all data from sql server table to a csv, I know I can get the desired result by:
sqlcmd -S . -d database -E -s, -W -Q "SELECT * FROM TABLENAME" > file.csv
I have many tables, so I want to create a .bat file that do the work for me, I have this:
set "list = A B C D"
for %%x in (%list%) do (
sqlcmd -S . -d database -E -s, -W -Q "SELECT * FROM %%x" > %%x.csv
)
But I am getting errors I don't know (I am not an expert in bat files). Why this does not work? How can I do what I want?
Spacing is important when using set (unless you're doing math with the /A switch). As written, the variable you're setting isn't %list%. It's %list %. Change your set command as follows:
set "list=A B C D"

Save column value to file SQL Server

How can I save first column from first row from query to file without additional character?
When I save data like this:
EXEC xp_cmdshell 'BCP "SELECT ''xxx'' " queryout D:\file.txt -w -T -S OMD-MG\SQL2008R2'
I've got:
additional \r\n at the end of file
When I save data like that:
EXEC xp_cmdshell 'BCP "SELECT ''xxx'' " queryout D:\file.txt -N -T -S OMD-MG\SQL2008R2'
I've got:
additional characters at front of file I think this is length
I try many parameter without satisfied result
Is there other option to save data to file from query without designer or management studio with correct data?
-N is a native binary format where any nullable or variable length fields are preceeded by their length. If you use -N with a non nullable, fixed-width field it will not be preceeded by its length.
If you want text data without the newlines you could try -r '' to specify the row terminator which is \n by default, e.g.:
bcp "select 'xxx'" queryout test.txt -c -t '' -r ''
..at least in SQL Server 2016 CTP I'm seeing that BCP tries to add padding to varchar columns. If you convert to text it seems to work alright:
bcp "select convert(text, col) from table" queryout file -c -t '' -r ''

How to format SQLCMD output

I am using below command line to run a SQL query using SQLCMD
sqlcmd -S Server -Q "select top 100 * From people" -d people -t 10
The table has 20 columns and when i look at output command line window wraps the text and makes it difficult to read.
I want my results to be displayed the same way it displays in SQL Server Management Studio (properly formatted). I am not looking for any grids, but i need all my columns to be displayed in row 1 and the results properly beneath.
Thanks in advance.
Answer
We can set the width of each column.
C:/> sqlcmd -S my_server
> :setvar SQLCMDMAXVARTYPEWIDTH 30
> :setvar SQLCMDMAXFIXEDTYPEWIDTH 30
> SELECT * from my_table
> go
We can also set it like this: sqlcmd -S my_server -y 30 -Y 30.
Details
SQLCMDMAXVARTYPEWIDTH (-y)
It limits the number of characters that are returned for the large variable length data type
SQLCMDMAXFIXEDTYPEWIDTH (-Y)
Limits the number of characters that are returned for the following data types
Note: setting -y has serious performance implications.
See https://learn.microsoft.com/en-us/sql/tools/sqlcmd-utility
Formatting issues usually pop up due to your console window.
One solution is to output to the file and use notepad/your favorite editor:
sqlcmd -S myServer -d myDB -E -Q "select top 100 * From people"
-o "output.txt"
This is how I isolated a scalar.
sqlcmd -S xxx.xxx.xxx.xxx,xxxxx -d MyDb -U myUser -P MyPassword -h -1 -W -Q "set NOCOUNT ON; select a from b where b.id='c'"

How to hide result set decoration in Psql output

How do you hide the column names and row count in the output from psql?
I'm running a SQL query via psql with:
psql --user=myuser -d mydb --output=result.txt -c "SELECT * FROM mytable;"
and I'm expecting output like:
1,abc
2,def
3,xyz
but instead I get:
id,text
-------
1,abc
2,def
3,xyz
(3 rows)
Of course, it's not impossible to filter the top two rows and bottom row out after the fact, but it there a way to do it with only psql? Reading over its manpage, I see options for controlling the field delimiter, but nothing for hiding extraneous output.
You can use the -t or --tuples-only option:
psql --user=myuser -d mydb --output=result.txt -t -c "SELECT * FROM mytable;"
Edited (more than a year later) to add:
You also might want to check out the COPY command. I no longer have any PostgreSQL instances handy to test with, but I think you can write something along these lines:
psql --user=myuser -d mydb -c "COPY mytable TO 'result.txt' DELIMITER ','"
(except that result.txt will need to be an absolute path). The COPY command also supports a more-intelligent CSV format; see its documentation.
You can also redirect output from within psql and use the same option. Use \o to set the output file, and \t to output tuples only (or \pset to turn off just the rowcount "footer").
\o /home/flynn/queryout.txt
\t on
SELECT * FROM a_table;
\t off
\o
Alternatively,
\o /home/flynn/queryout.txt
\pset footer off
. . .
usually when you want to parse the psql generated output you would want to set the -A and -F ...
# generate t.col1, t.col2, t.col3 ...
while read -r c; do test -z "$c" || echo , $table_name.$c | \
perl -ne 's/\n//gm;print' ; \
done < <(cat << EOF | PGPASSWORD=${postgres_db_useradmin_pw:-} \
psql -A -F -v -q -t -X -w -U \
${postgres_db_useradmin:-} --port $postgres_db_port --host $postgres_db_host -d \
$postgres_db_name -v table_name=${table_name:-}
SELECT column_name
FROM information_schema.columns
WHERE 1=1
AND table_schema = 'public'
AND table_name =:'table_name' ;
EOF
)
echo -e "\n\n"

Specify rowterminator when creating a file with SQLCMD

How do you specify the the row terminator when outputting query results using sqlcmd?
bcp is not an option.
sqlcmd -E -s" " -Q "Select * From SomeTable" -o C:\Output.txt -W
What is the default row terminator?
You can only choose column separator with -s. There is not option to specify row terminator.
So it is CR + LF because the output goes to command line. However, data may be truncated so you have to control the output width.
See sqlcmd for -s, -w, -W, -y, -Y etc
bcp may not be an option, as you say, but neither is row terminator in sqlcmd...
