I have a folder with 55 .sql files, SQL scripts.
Each file consists of 10000 insert statements. I'm using this command to run each file:
C:\sqlcmd -S . -d Minuf_Customers_July -i C:\ACL\MyScript3.sql
And I need to do it for MyScript1 , MyScript2.. to MyScript54.
Is there a way to loop through all the commands in the command prompt?
But it is important! that the each row will run separately because otherwise it will throw an "out of memory" error.
The DOS command for is your friend.
for %f in (*.sql) do sqlcmd -S . -d Minuf_Customers_July -i %f
The command help for gives details of various options.

I'm importing a set of data files in a folder into a SQL Server table. I'm able to run a recursive bcp if I enter it manually on the command line, but it doesn't work if I put it in a batch file.
The command is:
for /r %i in (*) do bcp databasename.dbo.tablename in %i -c -t -S servername -U username -P password -t "|"
The error returned is -c was unexpected at this time. If I remove the -c I get -t was unexpected at this time, and so on.
The problem was that the filenames ended up with space and dash characters when loaded to %i and these were interpreted as meaningful parts of the bcp command, which of course screwed it up. The simple but annoying solution is to make sure the directory names and filenames don't have spaces or dashes.
I was wondering if anyone can help.
I have a number of queries in SQL (all in separate *.sql files). I wanted to know if there is a way to run these queries automatically or mass run them to be saved to either a csv or txt file?
Also, I have come variables within these queries which will need to be amended on a weekly bases before the queries are run.
Thanks.

Could you please provide some additional help in relation to the variables? Previously I would declare and set variables as:
DECLARE #TW_FROM DATETIME
DECLARE #TW_TO DATETIME
SET #TW_FROM = '2015-11-16 00:00:00';
SET #TW_TO = '2015-11-22 23:00:00';
How do I do this using sqlcmd?
Yes, you can use sqlcmd to do this.
First of all - variables. You can refer to your variables in the .sql files using $(variablename) wherever you want to substitue the variable. For example,
use $(dbname);
select $(columnname) from table1 where column= '$(var1)'
You then call sqlcmd with the following command (note the argument -v variables)
sqlcmd -S servername -d database -i "yoursqlfile.sql" -v dbname="database" columnname="column" var1="Fred"
In order to output this to a file, you tag > filename.txt on the end
sqlcmd -S servername -d database -i "yoursqlfile.sql" -v dbname="database" columnname="column" var1="Fred" > filename.txt
If you want to output to a csv, you can also specify the delimiter using the argument -s (note the idfference with the capital S for server). So now we have
sqlcmd -S servername -d database -s "," -i "yoursqlfile.sql" -v dbname="database" columnname="column" var1="Fred" > filename.csv
If you want to output several commands to the same csv or txt file, use >> instead of > as it add to teh bottom of the file, rather than replacing it.
sqlcmd -S servername -d database -s "," -i "yoursqlfile.sql" -v dbname="database" columnname="column" var1="Fred" >> filename.csv
To run this for several scripts, you can put the statements in a batch file, and then change the variables every week.
You could write a batch file that uses sqlcmd:
MSDN sqlcmd
That will allow you to call script files in a loop and output the results to a file.
Convert your current scrips to a Stored Procedure.
You can then pass your variables to that and run the query.
If you have SQL Server agent available (SQL standard or better) you can use this to automate the running of the stored procedures.
Otherwise the same can be achieved with Task Scheduler in windows.
As for exporting to CSV this will be useful.
It depends on where your SQL Server is acutally running. It might be quite tricky to write anything to the location you want.
You could read about BCP.
My suggestion is:
Create an UDF (best is inline-UDF!) from all of your queries within your database. Than call them from EXCEL or any other fitting product. You might want to set up an Excel where all your queries are filled one on each Sheet automatically
I know how to setup a variable in a cmd file that passes the variable to SQL via sqlcmd.
Example:
sqlcmd -Usa -Ppass -d MASTER -v num="%num%" -i C:\scriptfile
My question is how can I define a variable in SQL that can be read outside of SQL. I know how to declare and define #variables in a SQL script but those are not recognized outside of when the SQL script runs.
My question is how to you pass a variable from SQL back to cmd?
Is there anyway to accomplish this?
Thank you
You can do this using scripting variable and using the -v option of SQLCMD utility. A small example from MSDN Documentation
Consider that the script file name is testscript.sql, Col1 is a scripting variable; your SQL script look like
USE test;
SELECT x.$(Col1) FROM Student x WHERE marks < 5;
You can then specify the name of the column that you want returned by using the -v option like
sqlcmd -v Col1 = "FirstName" -i c:\testscript.sql
Which will resemble to below query
SELECT x.FirstName FROM Student x WHERE marks < 5;
EDIT:
If you just want to capture the output from your script file then you can use -o parameter and specify a outfile like
sqlcmd -v Col1 = "FirstName" -i c:\testscript.sql -o output.txt
Thanks Rahul, you inadvertently answered my question. You can output your script results to a file via the -o option for SQLCMD.
Thinking about that I realized I could use the PRINT SQL to create a -o .cmd file that contains the .cmd syntax to define a variable. Then in the .cmd file I tell it to run the SQL created .cmd file and then the variable gets defined in the .cmd environment.
Kind of a round about way but works!!
Thanks!
If you just run a simple select to get your value or an exec spname that returns just the value you are after, you can use the following.
for /f "tokens=*" %a in ('sqlcmd -Usa -Ppass -W -h -1 -d MASTER -Q "select Column from table"') do set ResultVariable=%a
Remember to use %%a if putting this in a bat file
i have looked all over the internet and cant seem to find a solution to this problem.
i am trying to output query results as a CSV through using a combination of sqlcmd and windows batch. here is what i have so far:
sqlcmd.exe -S %DBSERVER% -U %DBUSER% -P %DBPASS% -d %USERPREFIX% -Q "SELECT Username, UserDOB, UserGender FROM TABLE" -o %USERDATA%\%USERPREFIX%\FACT_BP.CSV -h-1 -s","
is there something i'm missing here? some setting that only looks at the first column of the query results?
any advice at all would be a huge help - i'm lost.
Here is the reference page from MSDN on SQLCMD.
http://technet.microsoft.com/en-us/library/ms162773.aspx
I placed this command in a batch file in C:\temp as go.bat.
sqlcmd -S(local) -E -dmaster
-Q"select cast(name as varchar(16)), str(database_id,1,0), create_date from sys.databases"
-oc:\temp\sys.databases.csv -h-1 -s,
Notice I hard coded the file name and removed the "" around the field delimiter.
I get the expected output below.
Either the command does not like the system variables or something else is wrong. Please try my code as a base line test. It works for SQL 2012.
Also, the number of lines is always dumped to file. You must clear this out of the file. That is why I do not use SQLCMD for ETL.
Why not use BCP instead?
I have writing several articles on my website.

If I call sqlcmd with the -i command line switch, I'd like to be able to get the name of the file. So, I call
sqlcmd -S <servername> -E -i filename.sql
I'd like to be able to somehow have the contents of the script be able to print the filename without having to hard code it in the file. Looking at the variables and commands that are documented in BOL, I don't see anything like this, but just wanted to make sure. Thanks in advance.
Among the list of sqlcmd Scripting Variables, I don't see anything that has the name for the input file.
But you can send the file name as a parameter when you call sqlcmd.
Input file (filename.sql)
PRINT '$(p1)'
Sqlcmd:
sqlcmd -S .\Server -i filename.sql -v p1="filename.sql"
May be you should explore powershell for this
