Problem with retrieving mySQL data with DATE column

I have this problem for data table in mySQL DB with column defined using DATE format such as

`InstallDate` date NOT NULL,

Then I use following lines to get the data:

SQLquery = ['SELECT * FROM db_abc']; Table_db_abc = fetch(dbConn, SQLquery);

I got Table_db_abc = [].

Actually, I checked that Table_db_abc is not empty. It shows basic info of the table correct. If I use

SQLquery = ['SELECT COLUMN1 FROM db_abc']; Table_db_abc_Col1 = fetch(dbConn, SQLquery);

Table_db_abc_Col1 will be shown correctly, until the column defined as DATE.

However, if in the SQLquery, I specifically make

"DATE_FORMAT(''%d-%m-%Y'', InstallDate) AS InstallDate"

for that column like

SQLquery = ['SELECT COLUMN1 DATE_FORMAT(''%d-%m-%Y'', InstallDate) AS InstallDate COLUMN0 FROM db_abc'];

Then it works.

So, what is the problem? Someone told me it is matlab's problem with presenting the data of that format. It gets the data. Just not present correctly.

Any thoughts? Thanks...
