Extracting DB schema (newbie Q)
|
|
Brand-new to Python (that's a warning, folks)
Trying to write a routine to import a CSV file into a SQL Server
table. To ensure that I convert the data from the CSV appropriately,
I"m executing a query that gives me the schema (data column names,
data types and sizes) from the target table.
What I think I want to do is to construct a dictionary using the
column names as the index value, and a list containing the various
attributes (data type, lenghth, precision).
If this is NOT a good approach (or if there is a better approach),
please issue a dope-slap, ignore the rest of this post and set me
straight.
If this is a good approach, I ran into a problem populating the
dictionary as I couldn't seem to figure out how to make the update()
method work by passing the name property of the row object; I kept
getting a "keyword can't be an expression" error.
What I was able to make work was to construct the command as a string
and run exec(<python command>), but seems there shoudl be a more
direct way of updating the dictionary.
TIA.
