The default value osql is the server default. Increased packet size can enhance performance on larger script execution where the amount of SQL statements between GO commands is substantial.
Microsoft testing indicates that is typically the fastest setting for bulk copy operations. A larger packet size can be requested, but osql defaults to the server default if the request cannot be granted.
The osql connection uses the options specified in the data source. When you reset the command terminator, do not use Transact-SQL reserved words or characters that have special meaning to the operating system, whether preceded by a backslash or not. Note that the query statement should not include GO. For example:. Use double quotation marks around the query and single quotation marks around anything embedded in the query.
The message number, state, and error level are displayed for errors of the specified severity level or higher. Nothing is displayed for errors of levels lower than the specified level. Use -1 to specify that all headers are returned with messages, even informational messages. If using -1 , there must be no space between the parameter and the setting -m-1 , not -m If you do not specify a parameter, or if you specify 0 , only error messages with a severity level 11 or higher are redirected.
If you specify 1 , all message output including "print" is redirected. These features are deactivated:. The -n , -O and -D options are no longer supported by osql. The osql utility is started directly from the operating system with the case-sensitive options listed here. The results are formatted and displayed on the screen stdout.
If no environment variables are set, the workstation user name is used. If you do not specify a server, the name of the workstation is used. Authentication is based on the Microsoft Windows account of the user running osql. The osql utility does not support CLR user-defined data types. To process these data types, you must use the sqlcmd utility.
In addition to Transact-SQL statements within osql , these commands are also available. The current osql utility works as if there is an implied GO at the end of any script executed, therefore all statements in the script execute. End a command by typing a line beginning with a command terminator.
You can follow the command terminator with an integer to specify how many times the command should be run. For example, to execute this command times, type:.
The results are printed once at the end of execution. Large statements should be spread across multiple lines. The command recall facilities of Windows can be used to recall and modify osql statements. When running stored procedures, osql prints a blank line between each set of results in a batch. With this list, it creates a SQLCMD script that writes out the results for each table to a different file in the directory you designate.
It then executes this script. The script writes a few preliminaries to the SQL File that will eventually be executed. The source for this procedure is here. Here is the script. Firstly, you need to change the parameters at the start of the script to specify your work directory, the name you want for your SQLCMD file, the name of your error file, the path to your preliminary SQL file with procedures or initialization stuff and the name of the database you want to execute the script against.
Then you need to create your credentials file along with the name of your server. You do this by executing the commented-out section at the beginning, filling in the credentials and executing just that batch. Now we are ready to try it out.
Such is the slight perversity of DOS batch files that it may not entirely run first time. Fortunately, your error log will tell you quite a bit, and if you read the attempt made at the SQLCMD file, this should indicate where things have broken. To debug, first delete the echo off line so you can see how the batch ran. There are more hints here. Once a script like this is bedded down, it seems to run consistently. It runs fast, and the amount of code seems less than in PowerShell.
