Method Detail

getDeletedTables

public static Set<String> getDeletedTables(String delete)

getInsertedDataFields

public static Map<String,Set<String>> getInsertedDataFields(String insert)

getUpdatedDataFields

public static Map<String,Set<String>> getUpdatedDataFields(String update)

getSelectReadDataFields

public static Map<String,Set<String>> getSelectReadDataFields(String select)

Given a SELECT, check what it returns is based on (columns and tables). Something like "select x from Foo" would give info on "Foo->{x}". However, at times, what is returned is not directly the content of a column, but rather some computations on it. For example, in "select avg(x) from Foo", we would still be just interested in the info that the data in "Foo->{x}" was used to compute the result.

Parameters:

select - SQL select command

Returns:

a map from table_names to column_names
