MAX_BLOB_RETURN_LEN
static final int MAX_BLOB_RETURN_LEN
The maximum length of the data returned from the BLOB stored procedures.This value is currently dictated by the maximum length of VARCHAR/VARBINARY, because these are the return types of the stored procedures.
- See Also:
- Constant Field Values
-
MAX_CLOB_RETURN_LEN
static final int MAX_CLOB_RETURN_LEN
The maximum length of the data returned from the CLOB stored procedures.This value is currently dictated by the maximum length of VARCHAR/VARBINARY, because these are the return types of the stored procedures, and the modified UTF8 encoding used for CLOB data. This threshold value could be higher (equal to
MAX_BLOB_RETURN_LEN
), but then the procedure fetching data from the CLOB must be rewritten to have more logic.For now we use the defensive assumption that all characters are represented by three bytes.
