Stored procedure in T-SQL transform to PostgreSQL - sql-server

Question

I have a stored procedure writen in T-SQL and I want to make it for PostgreSQL but I'm not so familiar with PostgreSQL.
My stored procedure look like this:
CREATE PROCEDURE usp_insert_allocated_time
#fld_project_id INT,
#fld_allocated_time INT
AS
DECLARE #project int;
SET #project = #fld_project_id;
DECLARE #allocated int;
DECLARE #time int;
BEGIN
SET #time = (SELECT SUM(fld_allocated_time)
FROM dbo.tbl_project_timesheet
WHERE fld_project_id =#project)
SET #allocated = (SELECT fld_allocated_days FROM dbo.tbl_project where fld_id = #project);
IF #allocated > #time
BEGIN
INSERT into dbo.tbl_project_timesheet(fld_project_id,fld_allocated_time)
VALUES(#fld_project_id,#fld_allocated_time);
END
ELSE
PRINT 'Not OK';
END
And I have to do something like this, but on line 10 I get this error:
ERROR: invalid input syntax for integer: "293.00"
SQL state: 22P02
Context: PL/pgSQL function
"SA_PRJ".usp_add_timesheet_record_new(integer,integer,numeric,numeric,character varying,character varying) line 10 at assignment

INSERT INTO "SD_PRJ".tbl_project_timesheet(fld_emp_id, fld_project_id, fld_is_allocated,fld_allocated_time, fld_achieved_time, fld_task_desc, fld_obs)
VALUES (p_uid,p_project_id,coalesce(alloc_id,0), p_allocated_time, p_achieved_time,p_task_desc, p_obs);
ELSE
RAISE NOTICE 'Not OK!!';
END IF;
END;
END

It's more complex version in PostgreSQL for what I want.

You don't really give enough information to try and fix your problem, but the error message is pretty descriptive. You are trying to put 293.00 into an integer. Here I can reproduce:
DO
$$
DECLARE
i INT;
BEGIN
i := 293.00;
RAISE NOTICE 'i=%', i;
END
$$;
This will raise:
ERROR: invalid input syntax for integer: "293.00"
SQL state: 22P02
Context: PL/pgSQL function inline_code_block line 6 at assignment
You need to change your variable to the same datatype as the data you are trying to assign to it. For example:
DO
$$
DECLARE
i NUMERIC(5, 2);
BEGIN
i := 293.00;
RAISE NOTICE 'i=%', i;
END
$$;
This works and outputs:
NOTICE: i=293.00
