Hi,
I'm trying to get data out of a MS SQL Server 2005 database from a
Python 2.5 script, using the odbc module - I can't easily get anything
more up-to-date installed on this system.
If I specify the query literally, like this:
import dbi, odbc
myQuery = """SELECT EnteredValue FROM SampleTests INNER JOIN
SampleResults
ON (SampleTests.SampleCode = SampleResults.SampleCode AND
SampleTests.AuditFlag = SampleResults.AuditFlag AND
SampleTests.TestPosition = SampleResults.TestPosition)
WHERE (SampleTests.SampleCode='foo' AND SampleTests.AuditFlag=0 AND
SampleTests.TestCode='bar' AND
SampleTests.TestStatus<900 AND SampleResults.ComponentName='IntMethod')
"""
conn=odbc.odbc("DSN=mydatabase;UID=myusername;PWD=mypassword")
cursor=conn.cursor()
cursor.execute(myQuery)
print cursor.fetchall()
conn.close()
...it works OK, but if I try to parameterise the query:
myQuery = """SELECT EnteredValue FROM SampleTests INNER JOIN
SampleResults
ON (SampleTests.SampleCode = SampleResults.SampleCode AND
SampleTests.AuditFlag = SampleResults.AuditFlag AND
SampleTests.TestPosition = SampleResults.TestPosition)
WHERE (SampleTests.SampleCode=%s AND SampleTests.AuditFlag=0 AND
SampleTests.TestCode=%s AND
SampleTests.TestStatus<900 AND SampleResults.ComponentName='IntMethod')
"""
...
cursor.execute(myQuery, ('foo', 'bar'))
...I get:
dbi.program-error: [Microsoft][ODBC SQL Server Driver][SQL
Server]Incorrect syntax near 's'. in EXEC
Any idea what I'm doing wrong please? Apologies if I've missed something
stupid. I get the same error if I only specify one of the parameters
with %s and leave the other one literal, by the way.
Thanks,
Tom
