Hi postgres fans,
i'm already using the crosstab function but it shows up an issue with multiple results in the same category. example
table:
row_name cat value
----------+-------+-------
row1 cat1 val1
row1 cat1 val2
row1 cat3 val3
row1 cat4 val4
row2 cat1 val5
row2 cat2 val6
row2 cat2 val7
row2 cat4 val8
the crosstab function (as far as i know) usually assumes that only 1 value belongs to 1 category. but unfortunatelly in
ourdatabase it is possible that 1 category has 2 or more values.
is there a way to tell the crosstab function that it should show 2 rows when there is more then 1 value per category?
bynow only the first value of the selection criteria is shown.
thanks in advance for every hint.
sven
