Question: What do
I do to store emoticons in Oracle? I have a column
defined as VARCHAR2(255) and I want to store the emoticons
in this column. What do I do to represent emoticons in
an Oracle table?
My application is storing the emoji's correctly, but I
getting a ????? when I try to display the emoticon values in
SQL*Developer. How do I see the actual values stored
in the Oracle table?
Answer: Oracle normally uses a CLOB column
datatype for emoticons and uses the dbms_lob procedure to
store the emoticons in the table. However, the
emoticons are interpreted as follows, so just store the
values in a VARCHAR2 columns.
You can see the actual values stored in the Oracle table
by using SQL*Plus. For example, the string :) will be
interpreted as a smiley face emoticon. SQL*Developer
will not perform this translation and you get the unknown
string display of "???????".
You can also store strings as emoticons using these
characters:
:) :( :P
D ;)
As we see, the emoticons are stored as normal character
strings and the images are translated automatically by the
front-end application, changing the characters into the
emoji images.
