getDynamicDateColumnSQL

public String getDynamicDateColumnSQL(DynamicDateColumn column)

The text conversion of a date column is very DB specific. A mechanism combining concat and extract functions is used by default. Depending on the DB dialect a more polished approach can be used. For instance,

• In Oracle and Postgres the 'to_char' function is used.
• In Mysql, 'date_format'
• In H2, the 'to_char' function is not used as it's only available since version 1.3.175 and we do need to support older versions.
