I'm looking for an easy python way to compare column types from SQLAlchemy to base types. For example, if my column type is a VARCHAR of any length, I want to read it as a string. I can read the column type okay, but I'm not sure an easy way to verify it's basic type... it would be nice if I could use something like "if isinstance(mycolumn, int)" - but I'm new to python and not sure how this would work. Here's what I have so far: from sqlalchemy import MetaData from sqlalchemy import create_engine, Column, Table engine = create_engine('mysql+mysqldb://user:pass@localhost:3306/mydb', pool_recycle=3600) meta = MetaData() meta.bind = engine meta.reflect() datatable = meta.tables['my_data_table'] [c.type for c in datatable.columns] Output: [INTEGER(display_width=11), DATE(), VARCHAR(length=127), DOUBLE(precision=None, scale=None, asdecimal=True)] My end purpose is twofold, first because I want to format the output based on the type when I load it into my jQuery jqGrid. The second, is I'm slowly converting non-normalized data tables into a normalized structure, and want to ensure that I keep my types consistent - (to make sure my numbers in the previous table are stored as numbers and not strings...)
