TypeORM-NestJs Join on Json column - mysql

Question

join two mysql tables using typeorm-NestJs
where table 1(t1) is normal table
& table 2(t2) has a column which containts JSON data
now I need to join them based on t1.id == t2.column_name.id
but I am getting error on that query
query I am using :-
const results = await this.connection.createQueryBuilder(ABCEntity,'t1')
.innerJoinAndMapMany('t1.Id',xyzEntity,'t2','t1.Id = t2.column_name.$.Id')
.where('t1.Id = :Id',{Id: id})
.getMany()
.catch(err => console.log(err));
Error I am getting :-
code: 'ER_PARSE_ERROR',
errno: 1064,
sqlMessage: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.Id WHERE `t1`.`Id` = 'b6D812aF-9e22-4a5a-a292-6rc5021bfv0a'' at line 1",
sqlState: '42000',

Answer 1

what worked for me was, everything in backticks
for eg : `t1.Id = t2.column_name->'$.Id'
const results = await this.connection.createQueryBuilder(ABCEntity,'t1')
.innerJoinAndMapMany('t1.Id',xyzEntity,'t2',`t1.Id = t2.column_name->'$.Id'`)
.where('t1.Id = :Id',{Id: id})
.getMany()
.catch(err => console.log(err));
