bool odbc_binmode(resource $result_id, int $mode)
Enables handling of binary column data. ODBC SQL types affected are BINARY, VARBINARY, and LONGVARBINARY.
When binary SQL data is converted to character C data, each byte (8 bits) of source data is represented as two ASCII characters. These characters are the ASCII character representation of the number in its hexadecimal form. For example, a binary 00000001 is converted to "01" and a binary 11111111 is converted to "FF".
| ||>0||return as is|
| ||>0||return as char|
If odbc_fetch_into() is used, passthru means that an empty string is returned for these columns.
TRUE on success or
FALSE on failure.
- resource $result_id: The result identifier.
result_idis 0, the settings apply as default for new results.
Note: Default for longreadlen is 4096 and
modedefaults to ODBC_BINMODE_RETURN. Handling of binary long columns is also affected by odbc_longreadlen().
- int $mode: Possible values for
ODBC_BINMODE_PASSTHRU: Passthru BINARY data
ODBC_BINMODE_RETURN: Return as is
ODBC_BINMODE_CONVERT: Convert to char and return
- Default for longreadlen is 4096 and mode defaults to ODBC_BINMODE_RETURN. Handling of binary long columns is also affected by odbc_longreadlen().
