The opposite of making a trimming (trimming) is making a padding (filling), so the functions to be used should be PADL()
and PADR()
.
I get it, thank you !

Mysql has the function concat()
to concatenate strings as it can receive N
arguments you can put anything at the beginning and at the end.
update tabela set campo = concat('inicio ', campo, ' fim') where id = ?
Thank you very much !

You can use the || operator (string concatenation):
select 'Hello' || ' ' || 'World';
returns Hello World
.
Doesn’t work for UPDATE
, the field looks like 0
and both in the terminal and in PHP this select 'Hello' || ' ' || 'World';
returns 0
also. That is, you didn’t concatenate in mysql.
Hi, Jose. Note the tags under the question, the DB is mysql. In this case, the ||
does not serve. The ||
mysql is the OR for boolean values, and mysql |
OR for numerical values.
