The above code function is not complete, as appropriate reference;

Parameter resolution:

Connection conn, database link java.sql.Connection;

String SQL, which needs to be performed to find the SQL java.lang.String;

Object[] Paras, which can support integer and string arguments, depending on the parameters to be passed in for the lookup, type Object

Arraylist

Statement Explanation:

ResultSetMetaData RSMD = Ss.getmetadata (); You can get the column information for the results of the SQL query

int columnnum = Rsmd.getcolumncount (); Get the number of columns in the result set

Rsmd.getcatalogname (i) to obtain the name of the column in the order of the data

Ss.getobject (i) Getting the data for the current column from the result set
