- sql: CAST(value AS type)
table: ANY.cast(TYPE)
- description: Returns a new value being cast to type type. A CAST error
throws an exception and fails the job. When performing a cast operation that
may fail, like STRING to INT, one should rather use TRY_CAST, in order to
handle errors. If "table.exec.legacy-cast-behaviour" is enabled, CAST behaves
like TRY_CAST. E.g., CAST('42' AS INT) returns 42; CAST(NULL AS STRING) returns
NULL of type STRING; CAST('non-number' AS INT) throws an exception and fails
the job.

that the input is well-formed UTF-8 and throws on invalid sequences. Use
MAKE_VALID_UTF8 to substitute the Unicode replacement character `U+FFFD` for
invalid bytes, TRY_CAST to return NULL, or set
"table.exec.legacy-bytes-to-string-cast" to "true" to restore the prior
silent-substitution behavior.
Review Comment:
can we have sql more consistent: in some places it is with back ticks, in
some without
