hello,
if you want to edit a memo , you can use a TDbmemo component : see the field
Notes
in my database example coming with lazarus :
Deadly Mushrooms
.

Thanks for replying, the fields I want to edit are first and last name, which are of the text type, not memo

hello,
you must use the
varchar
type for simple text , the
text
type is for
memo
.
Example for my
deadly mushrooms
database :
Code: SQL
[Select]
[+]
[-]
BEGIN
TRANSACTION
;
CREATE
TABLE
`DeadlyMushrooms`
-- This table created by Jurassic Pork
-- for Free Pascal Lazarus
-- Create date:2013-08-05 23:55:09
(
ID
INTEGER
NOT
NULL
PRIMARY
KEY
AUTOINCREMENT
,
Scientific_Name
VARCHAR
NOT
NULL
,
Common_Name
VARCHAR
,
`Order`
VARCHAR
,
`Genus`
VARCHAR
,
`Notes`
TEXT
,
`Picture`
BLOB
,
`Image_Link`
VARCHAR
)
;
friendly, J.P
