Prisma deploy error for mysql

#1

I have got an error while deploying prisma. I have created a very simple table in relationship which couldn’t end in success. I tried multiple sources and multiple table definitions but I always got this error “Duplicate column name”.

Database:mysql

type Contact @db(name: “contact”) {

id: Int! @id

info: String!

type: String!

customerid: Customer

}

type Customer @db(name: “customer”) {

id: Int! @id

contact: [Contact]

firstname: String!

lastname: String!

}

Error:

Contact (Type)

  • Created type Contact

  • Created field id of type Int!

  • Created field info of type String!

  • Created field type of type String!

  • Created field customerid of type Customer

Customer (Type)

  • Created type Customer

  • Created field id of type Int!

  • Created field contact of type [Contact!]!

  • Created field firstname of type String!

  • Created field lastname of type String!

ContactToCustomer (Relation)

  • Created an inline relation between Contact and Customer in the column customerid of table Contact
