odbc_binmode

Description

(ODBC SQL types affected: BINARY, VARBINARY, LONGVARBINARY)

• ODBC_BINMODE_PASSTHRU: Passthru BINARY data

• ODBC_BINMODE_RETURN: Return as is

• ODBC_BINMODE_CONVERT: Convert to char and return

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".

If odbc_fetch_into() is used, passthru means that an empty string is returned for these columns.

If result_id is 0, the settings apply as default for new results.
