How do I ignore the difference​s in DBMSs when reading data from a DB?

Question

My boss wants me to create a text parser that parses the below sentence and executes an SQL query.
'get table field1,field2,field3,...,fieldN [where SQL conditional statements]'
This corresponds to 'select field1, field2, field3, ..., fieldN from table where blahblah'.
Since different DBMSs have different formats for timestamp, that sentence has to be changed for each DBMS.
One way to ignore the differences is to make a complex text anlayzer that converts a certain type of timestamp string to one that fits each DBMS.
But it looks ridiculous to adopt such a solution when there might be an elegant solution.
LabVIEW DB Toolkit is not capable of concealing the differences.
Does anybody have a better idea than I do?

Answer 1

I remember having an issue like this when working with an older version of an Oracle server. I was able alter the session by setting 'NLS_TIMESTAMP_FORMAT'.

(PS The Format Into String and Scan From String functions work nicely with the correct date format specifiers. See the link below in my signature for ISO 8601 timestamp/string conversions)
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T
