C to SQL: Numeric
There are a total of ten HCL OneDB™ ODBC Driver C data types.
The numeric HCL
OneDB ODBC Driver C
data types are:
- SQL_C_DOUBLE
- SQL_C_FLOAT
- SQL_C_LONG
- SQL_C_SHORT
- SQL_C_SLONG
- SQL_C_STINYINT
- SQL_C_TINYINT
- SQL_C_ULONG
- SQL_C_USHORT
- SQL_C_UTINYINT
The following table shows the HCL
OneDB ODBC Driver SQL
data types to which numeric C data can be converted.
| fSqlType | Test | SQLSTATE |
|---|---|---|
| SQL_BIGINT | Data converted without truncation. | N/A |
| Data converted with truncation of fractional digits. | 01004 | |
| Conversion of data would result in loss of whole (as opposed to fractional) digits. | 22003 | |
| SQL_BIT | Data is 0 or 1. | N/A |
| Data is greater than 0, less than 2, and|not equal to 1. | 01004 | |
| Data is less than 0 or greater than or equal to 2. | 22003 | |
| SQL_CHAR SQL_LONGVARCHAR SQL_VARCHAR |
Number of digits < Column length. | N/A |
| Number of whole (as opposed to fractional) digits < Column length. | 01004 | |
| Number of whole (as opposed to fractional) digits > Column length. | 22003 | |
| SQL_DECIMAL SQL_INTEGER SQL_SMALLINT |
Data converted without truncation | N/A |
| Data converted with truncation of fractional digits. | 01004 | |
| Conversion of data would result in loss of whole (as opposed to fractional) digits. | 22003 | |
| SQL_DOUBLE SQL_REAL |
Data is within the range of the data type to which the number is being converted. | N/A |
| Data is outside the range of the data type to which the number is being converted. | 22003 |
HCL OneDB ODBC Driver ignores the value that the pcbValue argument of SQLBindParameter points to and the value of the cbValue argument of SQLPutData when it converts data from the numeric C data types. HCL OneDB ODBC Driver uses the size of rgbValue for the size of the numeric C data type.
