    hex, oct, bin integers in PostgreSQL 16

    SQL and integer notations NEW in PostgreSQL 16 – support for non-decimal notation of integer constants! PostgreSQL already has powerful support for string constants, with E’\t’, E’\011′, E’\u0009′ and U&’\0009′ all meaning the same thing (a “horizontal tab” character). However, PostgreSQL’s support for numerical constants has – up until now – been rather limited; it […]

    Aliases for sub-SELECTS in FROM clause

    What are aliases in SQL? SQL aliases in FROM clauses are used to give a result set a temporary name. A result set may be produced by a table or view name, sub-SELECT and/or VALUES clause. An alias is created with the AS keyword, but the grammar allows us to omit it. An alias only […]
