Database-migration ms sql to postgresql - postgresql

Question

I am getting a syntax error when converting between SQL Server to PostgreSQL. Any thoughts?
IF (var_port_with_bmrk_total_mv != 0 AND var_bmrk_info IS NOT NULL) THEN
BEGIN
insert into t$tmp_diff
select #asof_dt asof_dt,#choiceID choiceID ,p.input_array_type ,p.group_order, CONVERT(DECIMAL(32,10),p.port_value/#var_port_total_mv) port_value,convert(decimal(32,10), isnull(bmrk_value/#port_with_bmrk_total_mv,0)) bmrk_value
from t$tmp_port_sum p, t$tmp_bmrk_sum b
where p.input_array_type=b.input_array_type and p.group_order = b.group_order
END;
ELSE
Original before conversion
insert into #tmp_other_diff
select #asof_dt asof_dt,#choiceID choiceID , b.input_array_type,b.grouping,convert(decimal(32,10),0) port_value, (bmrk_value/#port_with_bmrk_total_mv) bmrk_value
from #tmp_bmrk_other_sum b
where b.key_value not in ( select p.key_value from #tmp_port_other_sum p)
Error message:
Error occurred during SQL query execution
Reason:
SQL Error [42601]: ERROR: syntax error at or near ","
Position: 9030
the relevant comma being:
CONVERT(DECIMAL(32,10),p.port_value

Answer 1

There is no convert() function in Postgres. Use the SQL standard cast or the Postgres extension ::data type. In this case:
...., cast(0 as decimal(30,10)) port_value, ....
OR
...., 0::decimal(30,10) port_value, ...
Note: No comma after the expression. In the original port_value is the column alias. You need to keep it that way.
