Usage notes¶

You can specify the SQL query to execute using one of the following options

• Specify the query string using the --query option.

• Use the --filename option to execute one or more files containing a SQL query or queries. For example:

  • snow sql -f myfile.sql

  • snow sql -f file1.sql -f file2.sql

• Specify the query as stdin and pipe it to the snow sql command, such as cat my.sql | snow sql.

• If your query contains special characters, such as the dollar sign in SYSTEM functions, that you do not want the shell to interpret, you can do either of the following:

  • Enclose the query in single quotes instead of double quotes, as in:

    snow sql -q 'SELECT SYSTEM$CLIENT_VERSION_INFO()'

  • Escape the special character, as in:

    snow sql -q "SELECT SYSTEM\$CLIENT_VERSION_INFO()"

• Use variables for templating SQL queries with a combination of a <% variable_name %> placeholder in your SQL queries and a -D command-line option, in the form:

  snow sql -q "select * from my-database order by <% column_name %>" -D "column_name=Country"
  

  Copy

  Note

  You can currently use the SnowSQL &variable_name and <% variable_name %> syntax for templates. However, Snowflake recommends using the <% variable_name %> syntax.

• Specify a scripting block in queries. For example:

  EXECUTE IMMEDIATE $$
  -- Snowflake Scripting code
  DECLARE
    radius_of_circle FLOAT;
    area_of_circle FLOAT;
  BEGIN
    radius_of_circle := 3;
    area_of_circle := pi() * radius_of_circle * radius_of_circle;
    RETURN area_of_circle;
  END;
  $$
  ;
  

  Copy

  Note

  When specifying the scripting block directly on the Snowflake CLI command line, the $$ delimiters might not work for some shells because they interpret that delimiter as something else. For example, the bash and zsh shells interpret it as the process ID (PID). To address this limitation, you can use the following alternatives:

  • If you still want to specify the scripting block on the command line, you can escape the $$ delimiters, as in \$\$.

  • You can also put the scripting block with the default $$ delimiters into a separate file and call it with the snow sql -f <filename> command.

snow sql --enhanced-exit-codes -q 'select 1' -f my.query

echo $?

Examples¶

• The following example uses the SQL SYSTEM$CLIENT_VERSION_INFO system function to return version information about the clients and drivers.

  snow sql --query 'SELECT SYSTEM$CLIENT_VERSION_INFO();'
  

  Copy

  select current_version();
  +-------------------+
  | CURRENT_VERSION() |
  |-------------------|
  | 8.25.1            |
  +-------------------+
  

• The following example shows how you can specify a database using a client-side variable:

  snow sql -q "select * from <% database %>.logs" -D "database=dev"
  

  Copy

  When executed, the command substitutes the value dev in the <% database %> variable to create the dev.logs identifier and then sends the select * from dev.logs SQL query to Snowflake for processing.

  Note

  You can currently use the SnowSQL &variable_name and &``{ variable_name }`` syntax for templates. However, Snowflake recommends using the <% variable_name %> syntax.

• This example shows how to pass in environment variables using the --env option:

  snow sql -q "select '<% ctx.env.test %>'" --env test=value_from_cli
  

  Copy

• By default, Snowflake CLI removes comments in SQL query from the output. The following example uses the --retain-comments option to include the comments in the query results.

  Assume the example.sql file contains the following statements and comment:

  select 'column1';
  -- My comment
  select 'column2';
  

  Copy

  When you execute the following command, -- My comment appears in the query results.

  snow sql -f example.sql --retain-comments
  

  Copy

  select 'column1';
  +-----------+
  | 'COLUMN1' |
  |-----------|
  | ABC       |
  +-----------+
  
  -- My comment
  select 'bar';
  +-----------+
  | 'COLUMN2' |
  |-----------|
  | 123       |
  +-----------+
