- SMALLINT
- INTEGER
- BIGINT
- VARBYTE(n)
The data type of the bit_mask_arg parameter varies depending upon the data type of the target_arg parameter. The following (target_arg, bit_mask_arg) input combinations are permitted.
| target_arg type | bit_mask_arg type |
|---|---|
| BYTEINT | BYTE(1) |
| BYTEINT | BYTEINT |
| SMALLINT | BYTE(2) |
| SMALLINT | SMALLINT |
| INTEGER | BYTE(4) |
| INTEGER | INTEGER |
| BIGINT | BYTE(8) |
| BIGINT | BIGINT |
| VARBYTE(n) | VARBYTE(n) |
The maximum supported size (n) for VARBYTE is 8192 bytes.
All expressions passed to this function must either match these declared data types or can be converted to these types using the implicit data type conversion rules that apply to UDFs. For example, BITOR(BYTEINT, INTEGER) is allowed because it can be implicitly converted to BITOR(INTEGER,INTEGER).
If any argument cannot be converted to one of the declared data types, an error is returned indicating that no function exists that matches the DML UDF expression submitted.
