When using PSQL's variables, I can run it as follows:
psql -d database -v var="'123'"
And I will then have access to the variable var when I type the following in the PSQL terminal:
select * from table where column = :var;
This variable feature also works when the SQL is read from a file:
psql -d database -v var="'123'" -f file.sql
But when I try to run the SQL as a single command:
psql -d database -v var="'123'" -c "select * from table where column = :var;"
I can't access the variable and get the following error:
ERROR: syntax error at or near ":"
Is it possible to pass variables to single SQL commands in PSQL?
It turns out that, as man psql explains, the -c command is limited to SQL that "contains no psql-specific features":
-c command, --command=command
Specifies that psql is to execute one command string, command, and then exit. This is useful in shell
scripts. Start-up files (psqlrc and ~/.psqlrc) are ignored with this option.
command must be either a command string that is completely parsable by the server (i.e., it contains no
psql-specific features), or a single backslash command. Thus you cannot mix SQL and psql meta-commands
with this option. To achieve that, you could pipe the string into psql, for example: echo '\x \\ SELECT
* FROM foo;' | psql. (\\ is the separator meta-command.)
It looks like I can do what I want by passing in the SQL using stdin:
echo "select * from table where column = :var;" | psql -d database -v var="'123'"
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 ''
I'm trying to export data from a table to a CSV file in an automated fashion, hence the VBScript.
Here is my code and error below:
bcp dbname "SELECT * FROM mytable" queryout C:\Test.csv -T -c -Uusername -Ppassword -Sdbservername
I've never used bcp but it looks like a command-line utility. If you want to execute that from a VBScript, you'll need to use WshShell.Run, as in the following example:
With CreateObject("WScript.Shell")
.Run "bcp dbname ""SELECT * FROM mytable"" queryout C:\Test.csv -T -c -Uusername -Ppassword -Sdbservername"
End With
Take note of the doubled quotes around your SQL statement.
bcp "SELECT * FROM mytable" queryout "C:\Test.csv" -T -c -Uusername -Ppassword -Sdbservername
You should not have dbname after bcp. I removed it. This should work.
I have TSQL insert statements in a multiple text file in a folder. I need to run on sql server using foreach loop in powershell. it should go to each file in a folder read the query execute that and terminate the connection again read the next file and do the same operation
invoke-sqlcmd -ServerInstance KUMSUSHI7 -Query (Get-Content | For-each "C:\Drill\Task\SAMS Automation\Query.txt")
Please help me on this
Invoke-Sqlcmd can take script file as a parameter, so no -Query is needed. There's an example on MSDN:
Invoke-Sqlcmd -InputFile "C:\TestSQLCmd.sql" | Out-File -filePath "C:\TestSQLCmd.rpt"
Thus, get a list of your sql files and pass the file names to Invoke-Sqlcmd like so,
gci "c:\some\path\*" -include *.sql | % {
Invoke-Sqlcmd -InputFile $_.FullName
}
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

(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.
