Import Data from a large .sql file in SQL SERVER

If you try to import a large .SQL file using SQL Server Management Studio, you may get an "Out of memory" error. To import the file successfully you can use the SQLCMD utility.

The sqlcmd utility lets you enter Transact-SQL statements, system procedures, and script files at the command prompt, in Query Editor in SQLCMD mode, in a Windows script file or in an operating system (Cmd.exe) job step of a SQL Server Agent job. This utility uses ODBC to execute Transact-SQL batches.

SQLCMD -S -i C:\Temp\.sql

-a packet_size -A (dedicated administrator connection)
-b (terminate batch job if there is an error)
-c batch_terminator
-C (trust the server certificate)
-d db_name
-e (echo input)
-E (use trusted connection)
-f codepage | i:codepage[,o:codepage] | o:codepage[,i:codepage]
-h rows_per_header
-H workstation_name
-i input_file
-I (enable quoted identifiers)
-k[1 | 2] (remove or replace control characters)
-K application_intent
-l login_timeout
-L[c] (list servers, optional clean output)
-m error_level
-M multisubnet_failover
-N (encrypt connection)
-o output_file
-p[1] (print statistics, optional colon format)
-P password
-q "cmdline query"
-Q "cmdline query" (and exit)
-r[0 | 1] (msgs to stderr)
-R (use client regional settings)
-s col_separator
-S [protocol:]server[\instance_name][,port]
-t query_timeout
-u (unicode output file)
-U login_id
-v var = "value"
-V error_severity_level
-w column_width
-W (remove trailing spaces)
-x (disable variable substitution)
-X[1] (disable commands, startup script, environment variables and optional exit)
-y variable_length_type_display_width
-Y fixed_length_type_display_width
-z new_password
-Z new_password (and exit)
