MySQL Character Set SQL Syntax So for ASCII character strings that use 1 byte per character, the LEN and DATALENGTH() should be equal. But in a prepared statement, someId is treated as a string so whole '45 or 1 = 1' is treated as a string and will compare Id with '45 or 1 =1" and this is always false and return an empty result set.
