- What are the rules for using COLLATE in a query?
You do need COLLATE in the string concatenation because you are mixing database-level meta-data (which uses the database's default Collation) and system-level meta-data (i e state_desc and permission_name) which comes from the hidden mssqlsystemresource database and usually has a Collation of Latin1_General_CI_AS_KS_WS
- postgresql - Postgres collate example in select? - Database . . .
PostgreSQL does not support = or LIKE on COLLATE This is because internally index ordering uses = and so even if the collation returns that they're equal PostgreSQL falls back to binary equal This is documented, Note that while this system allows creating collations that “ignore case” or “ignore accents” or similar (using the ks key), PostgreSQL does not at the moment allow such

- PostgreSQL: difference between collations C and C. UTF-8
Meaning, in a database that uses the UTF-8 encoding, en_US and en_US UTF8 are equivalent BUT, between that database and a database that uses the LATIN1 encoding, the en_US collations are not equivalent So, does this mean that C and C UTF-8 are the same? NO, that would be too easy!!! The C collation is an exception to the above-stated behavior
