PLPython function and multiple line insert
Hi everyone,
I hope, I am on the right list. If not my apology.
I'd like to insert multiple lines as following with PLPython:
SQL statement:
INSET INTO table1 (field1, field2, field3)
VALES ('abc', 'abc', TRUE),
('def', 'def', FALSE),
('ghi', 'ghi', TRUE);
Here the proposed function:
CREATE OR REPLACE FUNCTION insert_rows()
RETURNS boolean AS
$$
.
.
.
sql = "("INSERT INTO table1 (field1, field2, field3)
VALUES ('abc', 'abc', TRUE),
('def', 'def', FALSE),
('ghi', 'ghi', TRUE");"
pypl.execute(sql)
.
.
$$
LANGUAGE 'plpythonu' VOLATILE
I ran into trouble with quoting this SQL statement in PLPython (PostgreSQL
8.3.7). Any ideas/suggestions how to quote it either with pypl.execute()
or pypl.plan()?
Thanks for any suggestions and help in advance,
Andi

The statement looks incorrect from the python point of view (not just
plpython). You should quote multi-lined strings, or use an escape
character (\) like:
"""line 1
line 2"""
'''line 1
line2'''
'line 1\n\
line2'
So I would try to rewrite the statement with:
sql = """INSERT INTO table1 (field1, field2, field3)
VALUES ('abc', 'abc', TRUE),
('def', 'def', FALSE),
('ghi', 'ghi', TRUE);"""
pypl.execute(sql)
Show quoted text
Thanks for any suggestions and help in advance,
