SQL to C: Date
The date HCL OneDB™ ODBC Driver SQL data type is SQL_DATE.
The following table shows the HCL
OneDB ODBC Driver C
data types to which date SQL data can be converted. When HCL
OneDB ODBC Driver converts
date SQL data to character C data, the resulting string is in the
yyyy-mm-dd format.| fCType | Test | rgbValue | pcbValue | SQLSTATE |
|---|---|---|---|---|
| SQL_C_BINARY | Length of data < cbValueMax | Data | Length of data | N/A |
| Length of data > cbValueMax | Untouched | Untouched | 22003 | |
| SQL_C_CHAR | cbValueMax 11 | Data | 10 | N/A |
| cbValueMax < 11 | Untouched | Untouched | 22003 | |
| SQL_C_DATE | HCL OneDB ODBC Driver ignores the value of cbValueMax for this conversion. HCL OneDB ODBC Driver uses the size of rgbValue for the size of the C data type. | Data | 6 (This is the size of the corresponding C data type.) |
N/A |
| SQL_C_TIMESTAMP | HCL OneDB ODBC Driver ignores the value of cbValueMax for this conversion. HCL OneDB ODBC Driver uses the size of rgbValue for the size of the C data type. | Data (HCL OneDB ODBC Driver sets the time fields of the time stamp structure to zero.) |
16 (This is the size of the corresponding C data type.) |
N/A |
