I have a table and I'd like to pull one row per id with field values concatenated.
In my table, for example, I have this:
TM67 | 4 | 32556
TM67 | 9 | 98200
TM67 | 72 | 22300
TM99 | 2 | 23009
TM99 | 3 | 11200
And I'd like to output:
TM67 | 4,9,72 | 32556,98200,22300
TM99 | 2,3 | 23009,11200
In MySQL I was able to use the aggregate function GROUP_CONCAT
, but that doesn't seem to work here... Is there an equivalent for PostgreSQL, or another way to accomplish this?
This question is related to
sql
postgresql
group-concat
string-aggregation
Hope below Oracle query will work.
Select First_column,LISTAGG(second_column,',')
WITHIN GROUP (ORDER BY second_column) as Sec_column,
LISTAGG(third_column,',')
WITHIN GROUP (ORDER BY second_column) as thrd_column
FROM tablename
GROUP BY first_column
SELECT array_to_string(array(SELECT a FROM b),', ');
Will do as well.
Try like this:
select field1, array_to_string(array_agg(field2), ',')
from table1
group by field1;
Since 9.0 this is even easier:
SELECT id,
string_agg(some_column, ',')
FROM the_table
GROUP BY id
My sugestion in postgresql
SELECT cpf || ';' || nome || ';' || telefone
FROM (
SELECT cpf
,nome
,STRING_AGG(CONCAT_WS( ';' , DDD_1, TELEFONE_1),';') AS telefone
FROM (
SELECT DISTINCT *
FROM temp_bd
ORDER BY cpf DESC ) AS y
GROUP BY 1,2 ) AS x
and the version to work on the array type:
select
array_to_string(
array(select distinct unnest(zip_codes) from table),
', '
);
