[resolved] tMongoDBOutput inserts only String fields

Anonymous — Sat, 16 Nov 2024 11:18:46 GMT

Hello,
When I try to load data in a MongoDB database, all fields are loaded as String, even if, in the schema, the fields are Integer, BigDecimal, Boolean, Date...
Is there a way to insert data in MongoDB with correct types with tMongoDBOutput component ?

My job :
tFileInputXML --> tMap --> tMongoDBOutput
The fields are Integer (or Date or Boolean...) in all the components.
tMongoDBOutput component is used with " Generate JSON Document" option.

Thanks in advance.

Hi
MongoDB supports the following types: array, string, integer, float etc.. see
http://json-lib.sourceforge.net/apidocs/jdk15/constant-values.html#net.sf.json.xml.JSONTypes.ARRAY
On tMongoDBOutput component, you need to add an attribute called 'type' to the element, and then right click on the attribute, select 'set a fixed value' to set the type name such as "float" which you want to declare the type of this element.

Hi Shong,
Thanks for your answer.
Yes, I have succeeded to create Integer or Boolean fields with this method.
But no solution to create Date fields with the " Generate JSON Document" option.
I've contacted the Support to help me on this case, but no solution found with them.

Hi
Date is not a supported type by json, uses the default String type for it or generates each part of the year. For example:
{"year":2015,"month":03,"day":27}

Hi Shong,
Is there a way we can do this without using the " Generate JSON Document" option and still having the loop elements structure maintained in the tMongoDBOutput component.

I am able to create a Date field in MongoDB WITHOUT using the " Generate JSON Document" but I dont know how to group by a certain field and have repeating child elements in the tMongoDBOutput component.
Thanks,
