Unable to use variables in multiline statements (%%sql)

Variables can be used normally with the following syntax: [1] table = 'my_fancy_table' [2] %sql SELECT * FROM $table Unfortunately, when I want to create multiline sql statements (like the following) variables are not possible to use: [1] table = 'my_fancy_table' [2] %%sql SELECT name, firstname FROM $table Outputs: (psycopg2.ProgrammingError) syntax error at or near “$” LINE 1: SELECT * FROM $table;

Does I have to use a different variables syntax for multiline statements or do multiline statements simply not support variables?

Thanks in advance.

Status on this?

This problem has been resolved in 0.3.9

Just use : before the variable

For multiline SQL

name = 'Countess'

%%sql
select description 
from character 
where charname = :name
# output: [(u'mother to Bertram',)]

You can also use : in single line SQL

name = 'Countess'

%sql select description from character where charname = :name
# output: [(u'mother to Bertram',)]

Using : solves a similar but not quite the same things as $. : works for parameters but not for extending the query.

IE

part_of_query = "where sign_in_count > 10"

%sql select count(name) from users $part_of_query

works with $ but not for :

I made a PR for this, and I think it should resolve your issue @mrjoseph84 .

Try:

db_table = "my_schema.my_table"
%%sql 
CREATE TABLE {db_table} AS
SELECT x, CAST (y AS INT) as duration
FROM abc.def
