Hey, Using [eGenix mxODBC Database Connection at /db_bos] [Test] select * from t20_user_experience --> retrieves 2 rows -- 1 field has 200+ characters Z-SQL method using SAME db connection: /db_bos select uid from t20_user_experience (ok) select * from t20_user_experience --> python.exe - Application Error -- instruction at 0x... Ok to term, Cancel to Debug. Debug (Vis Studio): Runtime error -- abnormal program execution. Bottom Line: Z-SQL method crashes Zope when a field has 200+ characters in it! Progress: This problem started when I was trying to update fields w/ ~200+ characters using Z-SQL methods. I bypassed Z-SQL updates completely by running updates like this: def run_sql (sql, dsn): """ bypass z-sql ??? """ import mx.ODBC.Windows # Connect to the database (using iODBC) conn = mx.ODBC.Windows.DriverConnect('DSN=%s'%(dsn)) curs = conn.cursor() # Create a database cursor curs.execute(sql) # Execute a statement on the cursor conn.commit() curs.close() conn.close() # return "run_sql output: dsn=%s sql=%s "%(dsn,sql) return 1 Only to find the same data crashes zope upon reading the data into a resultset! I've been looking in: \python\Shared\DC\ZRDB at dbi_db.py and others to try and track down what code is running for Z-SQL. in dby_db.py --> def query(self,query_string, max_rows=9999999): return 'stop now!!' # This did NOT change anything!! what code is running??? Any help with: finding the code that runs to execute Z-SQL bypassing Z-SQL selects but still get the needed resultsets General tips on what may be happening would be so greatly appreciated!! ----------------------------------------------------------------------------- Environment: Plone 1.0.5, Zope 2.6.1, W2K Server, Interbase 6 -----------------------------------------------------------------------------
