I have a table that stores all of my columns as "varchar(150)".
Some of the columns in the table only contain money values and I would like to convert them to such (numeric datatype is best for money?).
Here is how the table looks like:
The table has about 1.6m rows, how can I using TSQL or SSIS efficiently convert the three columns from varchar to a more appropriate datatype for money?
Please let me know, I am looking for a descriptive example of how to make this work.
