Dot and Periods can't be used as values

[Ximaz]

Hi there.

I'm trying to select a row where and email can include multiple dots (or period).

Here is my request :

await sql<User[]>`SELECT ${sql(cols)} FROM users WHERE ${sql(fieldName)} = ${sql(fieldValue)} LIMIT 1`

Where, at runtime :

• cols is ["id"],
• fieldName is email,
• fieldValue is a.b.c@d.com (example)

Here is my error :

PostgresError: cross-database references are not implemented: a.b.c@d.com

  severity: 'ERROR',
  code: '42P01',
  position: '40',
  file: 'parse_relation.c',
  line: '3657',
  routine: 'errorMissingRTE'

Here is an other error for less dots :

I'd like to add that I had no issue when inserting such a row, where the email field included 2 dots.

Dont' put values inside sql()

await sql SELECT ${ sql(cols) } FROM users WHERE ${ sql(fieldName) } = ${ fieldValue } LIMIT 1
