Thread: Invalid syntax for integer
Hi,
I have two overloaded functions:
CREATE FUNCTION climate.plr_stations(csv_latitude text, csv_longitude text)
CREATE FUNCTION climate.plr_stations(v_id integer[], v_latitude double precision[], v_longitude double precision[], latitude double precision[], longitude double precision[])
The first function takes a comma-separated list of values and converts them to arrays before passing them to the second. The variables are declared in the first function as follows:
latitude double precision[];
longitude double precision[];
v_id integer[];
v_latitude double precision[];
v_longitude double precision[];
latitude := string_to_array( csv_latitude, ',' );
longitude := string_to_array( csv_longitude, ',' );
The second function is called from the first as follows:
result := climate.plr_stations( v_id, v_latitude, v_longitude, latitude, longitude );
The error message is:
ERROR: invalid input syntax for integer: "-123.1833"
The variables have the following values (see the source code for where box is assigned):
The second function is written in PL/R. I have included the full source of the first function below.
The only parameter that takes an integer value is the first: v_id. Everything else is a double precision (or array of double precision).
The same code runs successfully with more values. For example:
Using a single value for v_id, v_latitude and v_longitude, however, does not.
I have tried adding typecasts (::double precision[]) to v_latitude and v_longitude without success.
Any ideas?
Thank you.
Dave

Presumably, this is coming from where you try to assign the result of
array_agg to v_id. Have you looked at what's going to be assigned
there?
regards, tom lane
Hi,
I added the following code:
For the error condition, the data looks as follows:
If I comment out the following line, then there are no errors:
result := climate.plr_stations( v_id, v_latitude, v_longitude, latitude, longitude );
The following line, without aggregated variables, receives an error:
result := climate.plr_stations( ARRAY[967], ARRAY[49.2], ARRAY[-123.1833], latitude, longitude );
This leaves me to believe that there is nothing wrong with the array aggregation.
The following line does not generate errors:
Now I have a work-around: I can explicitly set the second (i.e., "last") value of the array to NULL when the array has only one element.
I do not understand why having more than two elements works, but a single value does not.
Any ideas?
Dave

Hi,
The work-around is as follows:
IF array_length( v_id, 1 ) = 1 THEN
SELECT array_append( v_id, NULL ) INTO v_id;
END IF;
result := climate.plr_stations( v_id, v_latitude, v_longitude, latitude, longitude );
This now works when v_id contains a single element.
