Conditional expression causing errors when not enclosed in opening and closing braces

ksrikanthr — Sat, 16 Nov 2024 01:36:11 GMT

I've the following in tDBInput (Amazon Redshift) -

"select ln_id, ln_typ from ln_table where 1=1" +

(

(context.load_type).equalsIgnoreCase("HISTORY") ? "" : (" and aqsn_dt <= rec_cren_dttm")

)

If I do not have the beginning and ending braces after the + sign as shown above, then I get an error in Talend saying - Type mismatch: cannot convert from String to boolean. What is the need of putting the braces around the whole conditional expression?

The query filed does not support ternary expression, you can define the query on a tJava before tDBInput, eg:

tJava

|onsubjobok

tDBInput--main...>

on tJava:

if((context.load_type).equalsIgnoreCase("HISTORY")){

context.query="select ln_id, ln_typ from ln_table where 1=1";

}else{

context.query="select ln_id, ln_typ from ln_table where 1=1 and aqsn_dt <= rec_cren_dttm";

}

In the Query field of tDBInput, set the query as: context.query
