Named placeholders are broken due to whitespace

[michaelborn]

Name placeholders like WHERE name = :name are broken and do not replace at all.

Example:

SELECT supplier_name, city FROM suppliers
WHERE supplier_id = :name

this formats as:

SELECT
  supplier_name,
  city
FROM
  suppliers
WHERE
  supplier_id =: name

Notice the =: and the space between the : and name - =: name

You can see this right on the demo page:

Note that positional placeholders are still formatted and replace correctly.

Seeing a similar issue with parameter injection, depending on the dialect.
When using TSql parameter injection works, when using StandardSql, SparkSql, and maybe others, an extra whitespace is added, and parameter injection does not work:

// Bad example
SqlFormatter.of(Dialect.SparkSql).format("@thing", Map.of("thing", "foo")); // Result: "@ thing"

// Good example
SqlFormatter.of(Dialect.TSql).format("@thing", Map.of("thing", "foo")); // Result: "foo"

If anyone bumps into this issue, a possible workaround is to add '@' as a named placeholder type:

Formatter sparkSqlFormatter = SqlFormatter
            .of(Dialect.SparkSql)
            // Required for named placeholders to work
            .extend(dialectConfig -> dialectConfig.plusNamedPlaceholderTypes("@"));
            // ... any other needed extensions
