Question

I have a query that joins two tables.
The join is done on several columns, including a dateTime column.
The problem that I have at the moment is that the one dateTime column stores milliseconds whereas the other table is populated from a file which does not contain milliseconds
Because of this the join will never return results.

Is there any way via SQl to ignore the milliseconds?

Answer 1

If aTable.date contains millisenconds and bTable.date does not, to compare them:

... WHERE convert(varchar, aTable.date, 120) = bTable.date

converting datetime to varchar with arg2=120 produce this format: ODBC canonical yyyy-mm-dd hh:mi:ss
