Rules and Guidelines for Google Cloud Spanner Mappings
Rules and Guidelines for Google Cloud Spanner Mappings
Use the following rules and guidelines when you create a mapping:
Ensure that the source and target table names contain only uppercase letters.
You cannot use the OR operator in a filter condition.
You must define a primary key in the target table. If you do not define a primary key in the target table, the mapping fails to delete the record or update the record in the target table.
