Member Data Documentation

m_byte_count

size_t sql_digest_storage::m_byte_count

m_charset_number

uint sql_digest_storage::m_charset_number

Character set number.

m_full

bool sql_digest_storage::m_full

m_hash

unsigned char sql_digest_storage::m_hash[DIGEST_HASH_SIZE]

m_token_array

unsigned char* sql_digest_storage::m_token_array

Token array.

Token array is an array of bytes to store tokens received during parsing. Following is the way token array is formed. ... <non-id-token> <non-id-token> <id-token> <id_len> <id_text> ... For Example: SELECT * FROM T1; <SELECT_TOKEN> <*> <FROM_TOKEN> <ID_TOKEN> <2> <T1>

Note

Only the first m_byte_count bytes are initialized, out of m_token_array_length.

m_token_array_length

size_t sql_digest_storage::m_token_array_length
