Method Detail

mapColumnsToProperties

protected int[] mapColumnsToProperties(ResultSetMetaData rsmd,
                                       PropertyDescriptor[] props)
                                throws SQLException

The positions in the returned array represent column numbers. The values stored at each position represent the index in the PropertyDescriptor[] for the bean property that matches the column name. Also tried to match snake case column names or overrides. If no bean property was found for a column, the position is set to PROPERTY_NOT_FOUND.

Overrides:

mapColumnsToProperties in class org.apache.commons.dbutils.BeanProcessor

Parameters:

rsmd - The ResultSetMetaData containing column information.

props - The bean property descriptors.

Returns:

An int[] with column index to property index mappings. The 0th element is meaningless because JDBC column indexing starts at 1.

Throws:

SQLException - if a database access error occurs
