Data Type Mappings
DB2 to TDV Data Types
The following limits apply to DB2 data type mapping:
| • | The maximum length for BINARY, CHAR, VARBINARY, and VARCHAR is 32000. |
| • | The minimum length for BINARY, CHAR, VARBINARY, and VARCHAR is 1. |
| • | The maximum precision (p) is 38. |
| • | The maximum scale (s) for CAST functions is 38. |
| • | When a DECIMAL/NUMERIC data type has a precision greater than 38, it is mapped to the DB2 DOUBLE data type. |
The following table shows the mapping from DB2 data types to TDV data types.
