 22.2.3.50 `mysql_query()'
 .........................
 
 `int mysql_query(MYSQL *mysql, const char *query)'
 
 *Description*
 
 Executes the SQL query pointed to by the null-terminated string
 `query'. Normally, the string must consist of a single SQL statement
 and you should not add a terminating semicolon (‘`;'’) or `\g' to
 the statement. If multiple-statement execution has been enabled, the
 string can contain several statements separated by semicolons. See
  c-api-multiple-queries.
 
 `mysql_query()' cannot be used for queries that contain binary data;
 you should use `mysql_real_query()' instead. (Binary data may contain
 the ‘`\0'’ character, which `mysql_query()' interprets as the end
 of the query string.)
 
 If you want to know whether the query should return a result set, you
 can use `mysql_field_count()' to check for this. See 
 mysql-field-count.
 
 *Return Values*
 
 Zero if the query was successful. Non-zero if an error occurred.
 
 *Errors*
 
    * `CR_COMMANDS_OUT_OF_SYNC'
 
      Commands were executed in an improper order.
 
    * `CR_SERVER_GONE_ERROR'
 
      The MySQL server has gone away.
 
    * `CR_SERVER_LOST'
 
      The connection to the server was lost during the query.
 
    * `CR_UNKNOWN_ERROR'
 
      An unknown error occurred.
