# Configuring SnowSQL¶

This topic describes how to configure SnowSQL using connection parameters, configuration options, and variables.

In this Topic:

## SnowSQL config File¶

The SnowSQL configuration file, named config, stores connection parameters, default settings, and variables. Text is stored in UTF-8 encoding.

Modify the configuration file as follows:

1. Open the config configuration file in a text editor. The default location of the file is:

Linux/macOS

~/.snowsql/

Windows

%USERPROFILE%\.snowsql\

Note

You can change the default location by including the --config <path> connection parameter when starting SnowSQL.

2. Modify settings in the following sections:

Attention

• The password is stored in plain text in the config file. You must explicitly secure the file to restrict access. For example, in Linux or macOS, you can set the read permissions to you alone by running chmod:

$chmod 700 ~/.snowsql/config  Note • If a value contains special characters (other than single or double quotes), you must enclose it in either single quotes or double quotes, e.g.: password = "my$^pwd"

• If a value contains quote characters in addition to other special characters, escape these quotes using the backslash (\) character, e.g.:

password = "my\$^\"\'pwd"


Note that escaping quote characters is optional in unenclosed values (i.e. values that do not contain other special characters).

• Multi-line values must be enclosed in three single or double quotes (''' or """), e.g.:

prompt_format='''[#FFFF00]‌[user]‌@[account]
[#00FF00]> '''


### Connection Parameters Section¶

In the [connections] section of the config file, optionally set the default connection parameters for SnowSQL, e.g. account name, region ID, user login credentials, and the default database and warehouse. You can also define named connections to make multiple simultaneous connections to Snowflake or store different sets of connection configurations.

### Configuration Options Section¶

Configure the behavior of SnowSQL by adding settings in the [options] section of the config file:

[options]
<option_name> = <option_value>


Where:

• <option_name> is the name of the option (case-insensitive). If an invalid name is specified, SnowSQL displays an error.

• <option_value> specifies a supported value (case-insensitive) for the option, as described below.

See SnowSQL Configuration Options Reference (in this topic) for descriptions of all valid options.

Note

In additon to setting the configuration options in the config file, you can set the options using either of the following methods:

• While connecting to Snowflake, you can use the -o or --option connection parameter to set these options. For more information, see Connection Parameters Reference.

• After connecting to Snowflake, you can use the !set command to set these options for the session. For more information, see Commands Reference.

### Variables Section¶

In the [variables] section of the config file, you can store values as variables for reuse. This feature enables you to use user-defined and database values in queries.

## SnowSQL Configuration Options Reference¶

Options modify the default SnowSQL behavior. You can set these options using any of the following methods:

• In the configuration file (as described in this topic).

• Using the -o or --option parameter when connecting to Snowflake.

• Using the !set command once connected to Snowflake.

Note

The option names and values are case-insensitive.

• The connection-specific connection parameters, which are the parameters in the config file’s named connection section, e.g. the section [connections.myconnection].

• The default connection parameters, which are the parameters in the [connections] section of the config file.

If the value is False, the precedence (from highest to lowest) is:

• The connection-specific connection parameters, which are the parameters in the config file’s named connection section, e.g. the section [connections.myconnection].

• The environment variable or the SnowSQL command-line parameter.

• The default connection parameters, which are the parameters in the [connections] section of the config file.

Default

True

### force_put_overwrite¶

Type

Boolean

Description

If enabled, SnowSQL forces the PUT command to upload (i.e. stage) data files from a local directory/folder on a client machine to the specified internal (i.e. Snowflake) stage without checking whether the files already exist in the stage. If the files are already present in the destination stage, the PUT command overwrites the existing files.

Default

force_put_overwrite=False

### friendly¶

Type

Boolean

Description

If disabled, SnowSQL suppresses the startup and exit messages.

Default

friendly=True

### insecure_mode¶

Default

insecure_mode=False

### key_bindings¶

Type

String (constant)

Description

Key bindings to use. Possible values:

• emacs: [CTRL]-a is home, [CTRL]-e is end. All Emacs key bindings for the REPL environment are available.

• vi: You can use all modal editing features offered by vi in the REPL environment.
