Question

Cant find the correct syntax for INSERT query with python informixdb

• python 2.6.6
• python INFORMIXDB version 2.5
• driver name : IBM Informix-ESQL
• driver version : 3.50.FC8
• on debian squeeze

here’s the doc – http://informixdb.sourceforge.net/manual.html#binding-parameters

>>> cursor.execute('INSERT INTO names VALUES(:first,:last,:age)',
...                dict(first='some', last='body', age=56) )

So i tried for example

 cursor.execute('INSERT INTO transit_auftrag_i VALUES(:auftragskey,:transitkunde,:status)',dict(auftragskey='erII',transitkunde='DMIeLE',status='OK') )

this is what i get in this example

<class '_informixdb.ProgrammingError'>
('PREPARE', -236, [{'message': 'Insert value list does not match column list', 'sqlstate': '21S01'}])
<class '_informixdb.ProgrammingError'>
('DESCRIBE', -410, [{'message': 'Syntax error or access violation in PREPARE or EXECUTE IMMEDIATE', 'sqlstate': '37000'}])
Segmentation fault

any hints what i could try please?

UPDATE: informix 11.50.xC8

UPDATE

thanks so far. I do the following query now which runs without errors, but also with no message from the cursor and it does not insert anything. If you have a suggestion it would be great.

cursor.execute("INSERT INTO transit_auftrag_i (auftragskey,transitkunde,status) VALUES (:a,:b,:c)", dict(a='A',b='B',c='C') )

Answer 1

You should list the columns explicitely that you want to populate:

INSERT INTO names (firstname, lastname, age) VALUES (:first,:last,:age)

Apperently your table has more columns than you supply, or they are in a different order.

Not stating the columns for an INSERT statement is a bad programming habit, that you should get rid off as quick as possible
