Simple string field as Memo

Post by m227 » Tue 09 Feb 2016 14:20

Dear Sirs,
I have simple TLiteQuery with SQL:

Code: Select all

SELECT '123' AS test;
When I execute it and try to look at results in Data Editor (or any grid) I get 'test' field as TMemo. I tried to set options.LongStrings to true or false with no change. Delphi 2006, LiteDac 2.5.14.

If you are using constants, concatenation, aggregating functions (MAX, AVG, ...), etc., SQLite returns the Unknown type for such fields. For correct data display, you should use DataTypeMapping ... apping.htm .
