[resolved] tFlowToIterate - on each Row: lookup and Run if condition

[Anonymous]

Hi,
i'm creating a job like this:
dbInput1--main-->tFlowToIterate--iterate-->
-->If there is a record-->
-->else -->
To test it i substituted dbOutputs with tLogRows.
There are no syntax errors, but what i receive in tLogRows are empty rows.
tFlowToIterate has the "Use the default (key, value) in global variables" option checked.
LS_frontiera_meetings is a tMysqlInput component that search if a key exist or not.
tJava_14 has this code:
int nb=((Integer)globalMap.get("tMysqlInput_8_NB_LINE"));
if(nb>0){
globalMap.put("hasData", true);
}else{
globalMap.put("hasData", false);
}
System.out.println("rows are: "+nb);
tJava15 and tJava16 are empty, i used them just to be able to connect to tLogRows.
Why do you think i'm receiving empty rows instead of the SugarCRMInput flow?
Thanks in advance

Hi
I don't understand why you use a tFlowToIterate to iterate each row if you don't use a variable in the query of tMysqlInput? Can you show us the query of tMysqlInput? And there is a job design problem, tJava_14 should begin to work after tMyslqInput finishes, the job looks like:
tSugarCRMInput--main--tFlowToIterate--iterate--tMysqlInput--main--tLogRow(or tJavaRow)-oncomponentok--tJava_14...other processing

Hi Shong,
thank you.
I succeed:
I used a flow like this (see image) to produce a Do While Loop - and an If Else Statement based on a Query Select.
I had to import into a CRM named "LS" every new or updated meetings from a CRM named "SKY".
============
tJava_2
============
globalMap.put("tMysqlInput_5_NB_LINE", 0);
============
tJava_1
============
int nb=((Integer)globalMap.get("tMysqlInput_5_NB_LINE"));
if(nb>0){
globalMap.put("hasData", true);
}else{
globalMap.put("hasData", false);
============
LS_MEETINGS_SEL
============
"SELECT
`meetings`.`id`
FROM `meetings`
ORDER BY date_entered desc
LIMIT 1"
}
If anyone needs further explenations, just ask.
If anyone has any ideas how to improve this flow, feel free to reply.
