I’m getting a strange error from the SQL Server JDBC driver. It is telling me that a column name is invalid even though the column is present, correctly named and the same query works fine when executed in SqlServer Management Studio.

The error is:

Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: The column name MarginCall is not valid.

    Problem solved. It was a simple mistake by me.

    My query was using an ‘AS’ clause in the select statement. I was trying to retrieve the column value from the ResultSet using the actual column name, instead of the column alias defined in the AS clause.

    Schoolboy error. Apologies for the time wasting.

    Many thanks to Steve B. for his suggestion to use ResultSet.getColumnNames(). Although the actual method call I used was ResultSet.getMetaData().getColumnName(columnIndex);
