hi All,
I have a use case where I have two tables product and LOB. Both have rlobid as a common field. I am fetching all rlobid from product table and storing in a variable (local!pdata). Now if I am passing these id in filter for LOB table , I am getting the below error. I want to fetch names from LOb table corresponding to a given rlobid. What possibly Im doing wrong here. Attached error code. I have inserted my QE code too. Kindly help. Thanks.
a!localVariables( local!pdata: index( a!queryEntity( entity: cons!PLC_DSE_PRODUCT_TYPE, query: a!query( selection: a!querySelection( columns: a!queryColumn( field: "rLobId" ) ), pagingInfo: a!pagingInfo( startIndex: 1, batchSize: - 1, ), ), fetchTotalCount: true(), ).data, "rLobId", null ), local!lobdata: index( a!queryEntity( entity: cons!PLC_DSE_LOB, query: a!query( logicalExpression: a!queryLogicalExpression( operator: "AND", filters: a!queryFilter( field: "rLobId", operator: "=", value: local!pdata ), ), pagingInfo: a!pagingInfo( startIndex: 1, batchSize: - 1, ), ), fetchTotalCount: true(), ).data, "name", null ), local!lobdata )
Expression evaluation error at function a!queryEntity [line 23]: Cannot apply operator [EQUALS] to field [rLobId] when comparing to value [TypedValue[it=197,v={TypedValue[it=1,v=1],TypedValue[it=1,v=1],TypedValue[it=1,v=1],TypedValue[it=1,v=2],TypedValue[it=1,v=2],TypedValue[it=1,v=2],TypedValue[it=1,v=3],TypedValue[it=1,v=4]}]].

Hi Shikha
The variable local!pdata would be of type List of Number, you can either cast it to Number using Cast function or apply "in" operator instead of "=".
Hi Hema,
I used the in operator too. Still same error comes.
I applied cast function on local!pdata and casted it to the Number type. I am getting only the first value (name) from the LOB table. I want to fetch all the names corresponding to the rLOBID. Currently, It is showing only first LOB name. Any suggestions ?
below change I made:
local ! pdata : cast(Type!Integer, index( a!queryEntity( entity: cons!PLC_DSE_PRODUCT_TYPE, query: a!query( selection: a!querySelection( columns: a!queryColumn( field: "rLobId" ) ), pagingInfo: a!pagingInfo( startIndex: 1, batchSize: - 1, ), ), fetchTotalCount: true(), ).data, "rLobId", null ),
In Appian, "Integer" and "List of Integer" are considered different types. So in your case, you need to make sure it's casting to a list of integer. The easiest way to do this is to use the tointeger() function like this:
local!pdata: tointeger( index( a!queryEntity( entity: cons!PLC_DSE_PRODUCT_TYPE, query: a!query( selection: a!querySelection( columns: a!queryColumn( field: "rLobId" ) ), pagingInfo: a!pagingInfo( startIndex: 1, batchSize: - 1, ) ), fetchTotalCount: true, ).data, "rLobId", null ) )
Hi Peter,
Thanks for the explanation. This worked. I am getting a list of Names. I also used IN operator.
One thing I need to ask , (local!pdata) has some repeated id values like 1,1,2,2,3. So for output,I should get name1 , name1 ,name2 ,name2 ,name 3 --- this types of output.
But I am getting distinct LOB names (local!lobdata).
How to include repeated value present in local!pdata and get names for that also ? Hope You understand this.
