DESCRIPTION

9       Executes  arbitrary commands against a SQL database and outputs the re‐
10       sults as a CSV:
11
12          usage: sql2csv [-h] [-v] [-l] [-V] [--db CONNECTION_STRING] [--query QUERY]
13                         [-e ENCODING] [-H]
14                         [FILE]
15
16          Execute an SQL query on a database and output the result to a CSV file.
17
18          positional arguments:
19            FILE                  The file to use as SQL query. If both FILE and QUERY
20                                  are omitted, query will be read from STDIN.
21
22          optional arguments:
23            -h, --help            show this help message and exit
24            --db CONNECTION_STRING
25                                  An sqlalchemy connection string to connect to a
26                                  database.
27            --query QUERY         The SQL query to execute. If specified, it overrides
28                                  FILE and STDIN.
29            -e ENCODING, --encoding ENCODING
30                                  Specify the encoding of the input query file.
31            -H, --no-header-row   Do not output column names.

EXAMPLES

34       Load sample data into a table using csvsql  and  then  query  it  using
35       sql2csv:
36
37          csvsql --db "sqlite:///dummy.db" --tables "test" --insert examples/dummy.csv
38          sql2csv --db "sqlite:///dummy.db" --query "select * from test"
39
40       Load data about financial aid recipients into PostgreSQL. Then find the
41       three states that received the most, while  also  filtering  out  empty
42       rows:
43
44          createdb recipients
45          csvsql --db "postgresql:///recipients" --tables "fy09" --insert examples/realdata/FY09_EDU_Recipients_by_State.csv
46          sql2csv --db "postgresql:///recipients" --query "select * from fy09 where \"State Name\" != '' order by fy09.\"TOTAL\" limit 3"
47
48       You  can  even  use  it  as a simple SQL calculator (in this example an
49       in-memory SQLite database is used as the default):
50
51          sql2csv --query "select 300 * 47 % 14 * 27 + 7000"
52
53       The connection string accepts parameters. For example, to set  the  en‐
54       coding of a MySQL database:
55
56          sql2csv --db 'mysql://user:pass@host/database?charset=utf8' --query "SELECT myfield FROM mytable"
