SearchDB(dbFile,
tblName = "DNA",
identifier = "",
limit = -1,
replaceChar = "-",
orderBy = "row_names",
countOnly = FALSE,

verbose = TRUE,
...)
参数----------Arguments----------
参数：dbFile

参数：replaceChar
Optional character used to replace any characters of the sequence that are not present in the DNA_ALPHABET.
可选字符用来代替任何字符的序列是不存在DNA_ALPHABET。
参数：orderBy
Character string giving the column name for sorting the results. Defaults to the order of entries in the database. Optionally can be followed by " ASC" or " DESC" to specify ascending (the default) or descending order.

详情----------Details----------
If RNA is present in the database then all U's are converted to T's before creating the DNAStringSet.
如果RNA是在数据库中，然后被转换为T的所有U创建DNAStringSet之前。
值----------Value----------
A DNAStringSet with the sequences that meet the specified criteria. The names of the DNAStringSet correspond to the value in the "row_names" column of the database.
一个DNAStringSet序列，满足指定的条件。 namesDNAStringSet对应的的“row_names”的数据库列的值。
