What is the syntax for using the SHOW PROVIDERS command in Databricks SQL?
The syntax for using the `SHOW PROVIDERS` command in Databricks SQL is:

`SHOW PROVIDERS [ [ LIKE ] regex_pattern ]`

Here, `regex_pattern` is an optional regular expression pattern that is used to filter the results of the statement. The leading and trailing blanks are trimmed in the input pattern before processing. The pattern match is case-insensitive.

For example, to list all the providers visible to you, use the command `SHOW PROVIDERS;`. To see a provider that matches a specific pattern, use the command `SHOW PROVIDERS LIKE 'pattern';`.

Refer to the documentation for more details and examples on using the `SHOW PROVIDERS` command in Databricks SQL.
