constructDistinctOnClause

public java.lang.String constructDistinctOnClause(java.util.ArrayList outputParameters,
                                                  java.lang.String baseQuery,
                                                  java.util.ArrayList baseParameters,
                                                  java.lang.String[] distinctFields,
                                                  java.util.Map otherFields)

Construct a 'distinct on (x)' filter. This filter wraps a query and returns a new query whose results are similar to POSTGRESQL's DISTINCT-ON feature. Specifically, for each combination of the specified distinct fields in the result, only the first such row is included in the final result.

Specified by:

constructDistinctOnClause in interface IDBInterface

Parameters:

outputParameters - is a blank arraylist into which to put parameters. Null may be used if the baseParameters parameter is null.

baseQuery - is the base query, which is another SELECT statement, without parens, e.g. "SELECT ..."

baseParameters - are the parameters corresponding to the baseQuery.

distinctFields - are the fields to consider to be distinct. These should all be keys in otherFields below.

otherFields - are the rest of the fields to return, keyed by the AS name, value being the base query column value, e.g. "value AS key"

Returns:

a revised query that performs the necessary DISTINCT ON operation. The arraylist outputParameters will also be appropriately filled in.

getMaxInClause

public int getMaxInClause()

Obtain the maximum number of individual items that should be present in an IN clause. Exceeding this amount will potentially cause the query performance to drop.

Specified by:

getMaxInClause in interface IDBInterface

Returns:

the maximum number of IN clause members.

getMaxOrClause

public int getMaxOrClause()

Obtain the maximum number of individual clauses that should be present in a sequence of OR clauses. Exceeding this amount will potentially cause the query performance to drop.

Specified by:

getMaxOrClause in interface IDBInterface

Returns:

the maximum number of OR clause members.

beginTransaction

public void beginTransaction()
                      throws ManifoldCFException

Begin a database transaction. This method call MUST be paired with an endTransaction() call, or database handles will be lost. If the transaction should be rolled back, then signalRollback() should be called before the transaction is ended. It is strongly recommended that the code that uses transactions be structured so that a try block starts immediately after this method call. The body of the try block will contain all direct or indirect calls to executeQuery(). After this should be a catch for every exception type, including Error, which should call the signalRollback() method, and rethrow the exception. Then, after that a finally{} block which calls endTransaction().

Specified by:

beginTransaction in interface IDBInterface

Throws:

ManifoldCFException
