I created a table but when I run the application more than once it gives this problem. Why does this happen?

environments {
  development{
    dataSource {
        dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
        url = "jdbc:jtds:sqlserver://localhost:1433/G2017;instance=SQLEXPRESS";
        username = "sa"
        password = "G2017"
        loggingSql = false
    }
}

  • What version of Grails? You can post your Datasource.groovy?

  • 2.5.1 version of the grails

  • Column name 'Mco_ane_in_id' in table 'MATERIAL_CONSULTA' is specified more than Once.

  • You could post your Datasource.groovy?

  • This application has many classes but when I created this gave this problem that I do not know how to solve :(

  • The error is very clear: GORM is trying to create the Mco_ane_in_id field in the MATERIAL_CONSULTA table, but it already exists. The same happens when trying to create the foreign key. Anyway, GORM is not identifying that these items already exist in the BD. Tried to create a bank from scratch to see if everything works?

  • I already erased the bank and created again and I did everything again but it gives the same problem... What I do??????????

  • Friend? I changed the name of the field and it worked.

Grails (through Hibernate) is trying to create the Mco_ane_in_id column, but it already exists in your database. Please post the code of your Materialquery class to verify that this column is not mapped twice in the bank. If that’s the case, it’ll be wrong anyway.
