Forum Post: RE: AX 2012 SQL X++ clause LIKE between two DB field

You can do that with the extended query syntax. For example:

filteredDs.addRange(fieldNum(FilteredTable, Field1)).value(strFmt(     "(%1.%2 like %3.%4)",     filteredDs.name(),     fieldStr(FilteredTable, Field1),     definitionDs.name(),     fieldStr(FilterDefiniton, Field1)));
