▪SQL data types, which indicate the data type of data stored at the data source (for example, the solidDB® server).
▪C data types, which indicate the data type of data stored in application buffers.
Each SQL data type corresponds to an ODBC C data type. Before returning data from the data source, the driver converts it to the specified C data type. Before sending data to the data source, the driver converts it from the specified C data type.
For information about driver-specific SQL data types, see the driver’s documentation.
