Subject Re: [IBO] DB grid display of text fields
Author Robert Martin
Hi Jason

Just checked it with another table defined as follows

CREATE TABLE PHONE (
ENTITYREF NUMERIC(11) NOT NULL,
DAYPHONE VARCHAR(30) CHARACTER SET UTF8 COLLATE UTF8,
AHPHONE VARCHAR(30) CHARACTER SET UTF8 COLLATE UTF8,
FAXPHONE VARCHAR(30) CHARACTER SET UTF8 COLLATE UTF8,
CELLPHONE VARCHAR(30) CHARACTER SET UTF8 COLLATE UTF8,
EMAILADDR VARCHAR(70) CHARACTER SET UTF8 COLLATE UTF8,
WEBSITE VARCHAR(50) CHARACTER SET UTF8 COLLATE UTF8
);
ALTER TABLE PHONE ADD CONSTRAINT PHONE_ENTITYREF
PRIMARY KEY (ENTITYREF);


When viewing the results in an IBTable or IBQuery (Select * from
phone), the EmailAddr field shows as (memo). I am using IBO 5.2.0 6

it should be pretty easy to whip up a test app at your end. If not I
can make something for you.

Thanks
