This post is regarding executing SQL scripts from DOS batch file by using sqlcmd.

When you want to setup new environment, you might need to run lots of database scripts manually. But fortunately we can avoid this manual step by using sqlcmd command line utility with the help of DOS batch file. 

Create folders and keep SQL scripts inside those folders and sub folders as

Scripts in Folder
Scripts in Folder

Tip: - You should keep your script name start with number so that they will run in same order.

Below is a sample script which execute all scripts inside folders and its sub folders

SET SQLLOG=%~dp0sql_log.txt
ECHO. Starting Script, Server: %SQLSERVER%, logging to : %SQLLOG%

CALL:runsql "1 Create Databases"
CALL:runsql "2 Create Schema"
CALL:runsql "3 Data\1 Insert"
CALL:runsql "3 Data\2 Insert"


::Function to run SQL script files in a Directory
echo. Executing Scripts in Directory:
echo. %~1
for %%G in (*.sql) do echo. sqlcmd -S"%SQLSERVER%" -E -e -i"%%G"
for %%G in (*.sql) do echo. sqlcmd -S"%SQLSERVER%" -E -e -i"%%G"
for %%G in (*.sql) do sqlcmd -S"%SQLSERVER%" -E -e -i"%%G" >> "%SQLLOG%"

In current script, I am using below options
-S [protocol:]server[instance_name][,port]
-e (echo input)
-E (use trusted connection)
-i input_file

Pushd command and popd command in a batch program is used to change the current directory from the one in which the batch program was run and then change it back.

Note: - Your SQL server should be in mixed mode.
