Oracle NoSQL Error Type mismatch in IN operator. LHS type: INTEGER RHS type: STRING - oracle-nosql

Question

I would like to do the following query SELECT * FROM ${TABLE_NAME} where id in $keys[]
When running using, ARRAY (JSON) as in the documentation example
let statement = `DECLARE $keys ARRAY(JSON); SELECT * FROM ${TABLE_NAME} where id in $keys[]`;
I have the following error
LHS type: INTEGER RHS type: STRING
How to solve this issue. any ideas ?

Answer 1

It means that the elements of the array that you are sending are string and not integers. Your ID column seems to be INTEGER.
I've supposed that in your program you have something like that
preparedStmt.set( '$keys', ["3","4","5","100"]);
So a first solution is to send an array of INTEGER
preparedStmt.set( '$keys', [3,4,5,100]);
Another solution is just change the type of the variable
let statement = `DECLARE $keys ARRAY(INTEGER); SELECT * FROM ${TABLE_NAME} where id in $keys[]`;
But if you have non integer values you will have the following error
preparedStmt.set( '$keys', ["3","4","5","100","BAD DATA"]);
here the error
NoSQLArgumentError: [ILLEGAL_ARGUMENT] Failed to create Field Value for variable '$keys': Invalid string for Integer: BAD DATA
In this case, I suggest to manage this at client level
preparedStmt.set( '$keys', [3,4,5,"100","BAD DATA"].map(i=>Number(i)).filter( value => !Number.isNaN(value) ) );
