Method Detail

select

public java.util.Collection select(java.lang.String sql)
                            throws java.sql.SQLException

Executes SQL query, projects results to dynamically generated interface implementation. Results are put to ArrayList. If result set has one column then string value of this column is put to resulting collection.

Parameters:

sql -

Returns:

ArrayList of dynamic proxies.

Throws:

java.sql.SQLException

select

public java.util.Collection select(java.lang.String sql,
                                   java.util.List params)
                            throws java.sql.SQLException

Executes SQL query, projects results to dynamically generated interface implementation. Results are put to ArrayList. If result set has one column then string value of this column is put to resulting collection.

Parameters:

sql -

params - Array of query parameters.

Returns:

ArrayList of dynamic proxies.

Throws:

java.sql.SQLException

select

public java.util.Collection select(java.lang.String sql,

params - Context to retrieve parameters from. In SQL parameters shall be present in a form ${param name}. This call preprocesses SQL and replaces ${...} with a question mark. At the same time it retrieves parameter value from the context

Returns:

ArrayList of dynamic proxies.

Throws:

java.sql.SQLException
