There are good reasons why some DBAs strongly oppose enabling this option, since it does open up a security hole. Well, actually, the security hole is the fault of Microsoft, since the command is either enabled or disabled at the server level.
What we really want is to give some users access to it, which denying others. Third, the DOS way to write text to a file is using the echo command. Nothing is as simple as it seems. Echo does generally write text. However, it cannot write an empty line.
Go ahead. Open a CMD shell, type in echo and see what happens. Then type in echo with a bunch of spaces and see what happens. What you get is the informative message: ECHO is on. Thanks a bunch, but that's not echoing what was on the command line.
I want my procedure to write blank lines when it finds them in the string. To fix this problem, use the echo. For whatever reason, having the period allows an empty line to be written.
Apparently, other characters work as well, but period seems to be the accepted one. One of the options was to insert the timestamp inside a separate table, however, as we were using transaction it was not possible at all. When the transaction was rolled back, the insert details were also reversed back. What actually we needed a persistent log to measure the performance of our query and it should not be impacted by SQL Server transaction.
It was very clear that we needed to write somewhere outside SQL Server. Of course yes, we can do that with the help of Ole Automation Procedures.
Please note that you should only enable Ole Automation Procedures if you really need it otherwise, it is best to keep it disabled. Once you go there, you can see the file in the folder and also find our text in it. Write to a table variable which will retain its values after the transaction rolls back, then insert the table variable rows into a real table you can query at your leisure.
No need to bring the file system into it. Yeah that was my immediate thought. You can unsubscribe at any time. EXEC master.. Here is a SP that I found a while ago and have been using to log any problems with my procedures. EXEC master. The following command exports the data stored in the authors table in the pubs database to authors.
All we are doing is passing arguments to the bcp executable. If the default database associated with the login does not contain the target object s , an error message is generated. The second argument queryout tells bcp the direction of data flow. In this case it indicates the data is flowing out of SQL Server using a query to specify the source data. The third argument authors. The file will be created in the directory in which the command is executed if no other is specified.
The fourth and fifth arguments -U and -P specify the login and password. The arguments are case-sensitive, so make sure they are capitalized. The second line is to specify the connection information SQL Server name, database name and Authentication method :.
The try structure is used to handle exceptions. The line with "while reader. Read " is used to read row by row the results of the SQL Query. This is used to handle errors. Show will show the error and Dts. TaskResult will show a failure red color if it fails. This code is used when an exception error is generate by the package.
If the presentation is important, Reporting Services is the best option. Press Preview and in the Save icon, select CSV comma delimited to save the file with the csv extension:. It is a very fast option.
Use it if you have millions of rows and you need to use the command line or if it is easy to call the command line from your program or script. The following example uses bcp to export the query results to a file named bcp. There are many other ways to export results. However, these options will inspire you to use other ones. SSMS destination to file option - This is the easiest option.
Used if you do not need to automate anything and you just one a txt report immediately.
