readDataType
protected DataType readDataType(CachedRow columnMetadataResultSet, Column column, Database database) throws DatabaseException
Processes metadata of a column, e.g. name, type and default value. We start with the result of the JDBCDatabaseMetaData
.getColumns() method. Depending on Database, additional columns might be present.- Parameters:
columnMetadataResultSet
- the result from the JDBC getColumns() call for the columncolumn
- logical definition of the column (object form)database
- the database from which the column originates- Returns:
- a DataType object with detailed information about the type
- Throws:
DatabaseException
- If an error occurs during processing (mostly caused by Exceptions in JDBC calls)
