appendSize

protected String appendSize(Column col,
                            String typeName)

Helper method to add size properties to the specified type. If present, the string "{0}" will be replaced with the size definition; otherwise the size definition will be appended to the type name. If your database has column types that don't allow size definitions, override this method to return the unaltered type name for columns of those types (or add the type names to the fixedSizeTypeNameSet).

Some databases support "type modifiers", for example the unsigned "modifier" in MySQL. In these cases the size should go between the type and the "modifier", instead of after the modifier. For example CREATE table FOO ( myint INT (10) UNSIGNED . . .) instead of CREATE table FOO ( myint INT UNSIGNED (10) . . .). Type modifiers should be added to typeModifierSet in subclasses.

insertSize

protected String insertSize(String typeName,

Helper method that inserts a size clause for a given SQL type.

Parameters:

typeName - The SQL type e.g. INT

size - The size clause e.g. (10)

Returns:

The typeName + size clause. Usually the size clause will be appended to typeName. If the typeName contains a marker : {0} or if typeName contains a modifier the size clause will be inserted appropriately.

Create a DELETE statement for the specified Select. If the database does not support the bulk delete statement (such as cases where a subselect is required and the database doesn't support subselects), this method should return null.

toUpdate

Returns the SQL for a bulk operation, either a DELETE or an UPDATE.

Parameters:

mapping - the mapping against which we are operating

sel - the Select that will constitute the WHERE clause

store - the current store

Create SQL to delete the contents of the specified tables. The default implementation drops all non-deferred RESTRICT foreign key constraints involving the specified tables, issues DELETE statements against the tables, and then adds the dropped constraints back in.

matchErrorState

protected int matchErrorState(Map<Integer,Set<String>> errorStates,

Determine the more appropriate type of store exception by matching the SQL Error State of the the given SQLException to the given Error States categorized by error types. Dictionary subclass can override this method and extract SQLException data to figure out if the exception is recoverable.

Parameters:

errorStates - classification of SQL error states by their specific nature. The keys of the map represent one of the constants defined in StoreException. The value corresponding to a key represent the set of SQL Error States representing specific category of database error. This supplied map is sourced from sql-error-state-codes.xml and filtered the error states for the current database.

ex - original SQL Exception as raised by the database driver.

Returns:

A constant indicating the category of error as defined in StoreException.

Parameters:

subtype - A constant indicating the category of error as defined in StoreException.

ex - original SQL Exception as raised by the database driver.

Returns:

false if the error is fatal.
