Member Function Documentation

constructor()

FreetdsSqlUtil::FreetdsSavepointHelper::constructor	(	AbstractDatasource	ds,
		*string	savepoint = 'x'+get_random_string(31)
	)

Creates the object.

Note

MS SQL Server savepoint identifiers cannot be longer than 32 character by default; the default savepoint value uses the unique hash for the object, which is 40 characters long, so we have to use another algorithm to create the savepoint string on Oracle
