quote-nameclj
(quote-name driver identifier-type & components)Inputs: [driver :- s/Keyword identifier-type :- hx/IdentifierType & components]
Quote unqualified string or keyword identifier(s) by passing them to hx/identifier, then calling HoneySQL format
on the resulting Identifier. Uses the sql.qp/quote-style of the current driver. You can implement ->honeysql
for Identifier if you need custom behavior here.
(quote-name :mysql "wow") ; -> "wow"
(quote-name :h2 "wow") ; -> ""WOW""
You should only use this function for places where you are not using HoneySQL, such as queries written directly in
SQL. For HoneySQL forms, Identifier is converted to SQL automatically when it is compiled.
Inputs: [driver :- s/Keyword identifier-type :- hx/IdentifierType & components] Quote unqualified string or keyword identifier(s) by passing them to `hx/identifier`, then calling HoneySQL `format` on the resulting `Identifier`. Uses the `sql.qp/quote-style` of the current driver. You can implement `->honeysql` for `Identifier` if you need custom behavior here. (quote-name :mysql "wow") ; -> "`wow`" (quote-name :h2 "wow") ; -> "\"WOW\"" You should only use this function for places where you are not using HoneySQL, such as queries written directly in SQL. For HoneySQL forms, `Identifier` is converted to SQL automatically when it is compiled.
select-clause-alias-everythingclj
(select-clause-alias-everything select-clause)Make sure all the columns in select-clause are alias forms, e.g. [:table.col :col] instead of :table.col.
(This faciliates our deduplication logic.)

select-clause-deduplicate-aliasesclj
(select-clause-deduplicate-aliases select-clause)Make sure every column in select-clause has a unique alias. This is useful for databases like Oracle that can't
figure out how to use a query that produces duplicate columns in a subselect.
