Q: How can I remove the first few of bytes while creating thematic maps with SuperMap iDesktop 7C?
A: For the UDB and Oracl datasources you can use the expression substr(field_name,4). For the sqlServer dataource, you can use the expression SUBSTRING(field_name,4,len(field_name)-3) to remove the first three bytes.
1. Are there any limits to length of the name of the dataset created in the Oracle datasource with SuperMap iDesktop 7C?
A: The name of the dataset cannot exceed 30 bytes. Because of the naming rules of table names in the database, the number of letters cannot exceed 30.
