The cockroach sqlfmt
command changes the textual formatting of
one or more SQL queries. It recognizes all SQL extensions supported by
CockroachDB.
A web interface to this feature is also available.
This is an experimental feature. The interface and output are subject to change.
Synopsis
Use the query formatter interactively:
$ cockroach sqlfmt <flags>
<sql stmt>
CTRL+D
Reformat a SQL query given on the command line:
$ cockroach sqlfmt <flags> -e "<sql stmt>"
Reformat a SQL query already stored in a file:
$ cat query.sql | cockroach sqlfmt <flags>
Flags
The sqlfmt command supports the following flags.
| Flag | Description | Default value |
|---|---|---|
--execute-e |
Reformat the given SQL query, without reading from standard input. | N/A |
--print-width |
Desired column width of the output. | 80 |
--tab-width |
Number of spaces occupied by a tab character on the final display device. | 4 |
--use-spaces |
Always use space characters for formatting; avoid tab characters. | Use tabs. |
--align |
Use vertical alignment during formatting. | Do not align vertically. |
--no-simplify |
Avoid removing optional grouping parentheses during formatting. | Remove unnecessary grouping parentheses. |
Examples
Reformat a query with constrained column width
Using the interactive query formatter, output with the default column width (80 columns):
Start the interactive query formatter:
$ cockroach sqlfmtPress Enter.
Run the query:
> CREATE TABLE animals (id INT PRIMARY KEY DEFAULT unique_rowid(), name STRING);Press CTRL+D.
CREATE TABLE animals ( id INT PRIMARY KEY DEFAULT unique_rowid(), name STRING )
Using the command line, output with the column width set to 40:
$ cockroach sqlfmt --print-width 40 -e "CREATE TABLE animals (id INT PRIMARY KEY DEFAULT unique_rowid(), name STRING);"
CREATE TABLE animals (
id
INT
PRIMARY KEY
DEFAULT unique_rowid(),
name STRING
)
Reformat a query with vertical alignment
Output with the default vertical alignment:
$ cockroach sqlfmt -e "SELECT winner, round(length / (60 * 5)) AS counter FROM players WHERE build = $1 AND (hero = $2 OR region = $3);"
SELECT
winner, round(length / (60 * 5)) AS counter
FROM
players
WHERE
build = $1 AND (hero = $2 OR region = $3)
Output with vertical alignment:
$ cockroach sqlfmt --align -e "SELECT winner, round(length / (60 * 5)) AS counter FROM players WHERE build = $1 AND (hero = $2 OR region = $3);"
SELECT winner, round(length / (60 * 5)) AS counter
FROM players
WHERE build = $1 AND (hero = $2 OR region = $3);
Reformat a query with simplification of parentheses
Output with the default simplification of parentheses:
$ cockroach sqlfmt -e "SELECT (1 * 2) + 3, (1 + 2) * 3;"
SELECT 1 * 2 + 3, (1 + 2) * 3
Output with no simplification of parentheses:
$ cockroach sqlfmt --no-simplify -e "SELECT (1 * 2) + 3, (1 + 2) * 3;"
SELECT (1 * 2) + 3, (1 + 2) * 3
