clickhouse-format | ClickHouse Docs

Allows formatting input queries.

Keys:

--help or-h — Produce help message.
--query — Format queries of any length and complexity.
--hilite or --highlight — Add syntax highlight with ANSI terminal escape sequences.
--oneline — Format in single line.
--max_line_length — Format in single line queries with length less than specified.
--comments — Keep comments in the output.
--quiet or -q — Just check syntax, no output on success.
--multiquery or -n — Allow multiple queries in the same file.
--obfuscate — Obfuscate instead of formatting.
--seed <string> — Seed arbitrary string that determines the result of obfuscation.
--backslash — Add a backslash at the end of each line of the formatted query. Can be useful when you copy a query from web or somewhere else with multiple lines, and want to execute it in command line.
--semicolons_inline — In multiquery mode, write semicolons on last line of query instead of a new line.
