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 have a script with dynamic query. I want to execute the query and output its result to a file. I can't seem to figure out how to output result of an "execute" statement.
Sample code below.
declare #sql_text varchar(300)
select #sql_text = select 1
exec (#sql_text) > output.txt
To give more context. My actual script would be looping through the dynamic query and output to different files (dynamic filename as well).
You set the output file via the -o parameter to the isql client to execute the SQL. This will send the output to a file from any SQL be that normal or dynamic SQL.
So put the SQL in an input file and then run
isql -U user - P password -S -i input_filename -o output.txt
You can't call directly to a operating system file from within ASE itself without enabling xp_cmdshell which is a potential security issue (as it allows O/S commands to be run as the user running the Sybase dataserver) and is therefore prohibited in most sites.
I have created a BCP utility and I have wrapped it in a bat file. I have then created a daily task using Task Scheduler in Windows Server 2012.
The function of the BCP utility is to rename a file called 'myfile.csv' (located in C:) by adding a date stamp to it and updating the file with the result of a SQL query.
The codes currently stand as follows:
cd:\Program Files\ Microsoft SQL Server\Client SDK\ODBC\110\Tools\Binn
set vardate=%DATE:~4,10%
set varDateWithoutSlashes=%vardate:/=-%
ren C:\myfile.csv myfile_%varDateWithoutSlashes%.csv
bcp "SELECT TOP 100 ReservationStayID,NameTitle,FirstName,LastName,ArrivalDate,DepartureDate FROM MyDatabase.dbo.GuestNameInfo" queryout C:\myfile.csv -t, -c -S [ipaddress] -U sa -P 1234
My problem is that when the task runs, it renames the file correctly with a the date stamp but it seems that the SELECT query does not run as the file is empty (except the headers, which have been pre-loaded by the way).
What is wrong with my codes?
I should also add the following:
Are the double quotes in the select statement above correct? Or should they be single quotes?
Should the ipaddress in my codes above be in square brackets or should I remove them?
I have left the "Location" filed 'as is' in the Task Scheduler (please see screenshot below). Should that be filled? If yes, by what?
Thanks for helping out!
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.
http://craftydba.com/?p=1584
I have a huge database which I want to dump out using BCP and then load it up elsewhere. I have done quite a bit of research on the Sybase version of BCP (being more familiar with the MSSQL one) and I see how to USE an Import file but I can't figure out for the life of me how to create one.
I am currently making my Sybase bcp out files of data like this:
bcp mytester.dbo.XTABLE out XTABLE.bcp -U sa -P mypass -T -n
and trying to import them back in like this:
bcp mytester.dbo.XTABLE in XTABLE.bcp -E -n -S Sybase_157 -U sa -P SyAdmin
Right now, the IN part gives me an error about IDENTITY_INSERT regardless of if the table has an identity or not:
Server Message: Sybase157 - Msg 7756, Level 16, State 1: Cannot use
'SET IDENTITY_INSERT' for table 'mytester.dbo.XTABLE' because the
table does not have the identity property.
I have often used the great info on this page for help, but this is the first time i've put in a question, so i humbly request any guidance you all can provide :)
In your BCP in, the -E flag tells bcp to take identity column values from the input file. I would try running it without that flag. fmt files in Sybase are a bit finicky, and I would try to avoid if possible. So as long as your schemas are the same between your systems the following command should work:
bcp mytester.dbo.XTABLE in XTABLE.bcp -n -S Sybase_157 -U sa -P SyAdmin
Also, the -T flag on your bcp out seems odd. I know SQLServer -T is a security setting, but in Sybase it indicates the max size of a text or image column, and is followed by a number..e.g -T 32000 (would be 32Kbytes)
But to answer the question in your title, if you run bcp out interactively (without specifying -c,-n, or -f) it will step through each column, prompting for information. At the end it will ask if you want to create a format file, and allow you to specify the name of the file.
