Implicit estimate option controls the CMT getting total record count from source database.
Because getting record count costs too much time in some big source databases.

CMT supports exporting records with XLS format.
But it is not recommended that there are some records with BLOB/Binary or big Varchar types in the source database.
If the “Expression” option is checked, CMT will regard the string in the text box as a SQL expression, so the text will not be quoted with ‘’ in table’s DDL.
