Specifies one or more SQL statements to execute after connecting to the database and prior to fetching any rows from the database or writing any rows to the database. The statements are committed by the adapter after the last one is executed, or automatically if autocommit is specified or the statements are non-transactional (e.g. DDL statements). Bind parameters are not supported – the statements must be static statements. The adapter assumes that individual statements are separated by a semicolon. Each semicolon and backslash character that is integral part of a statement needs to be escaped by a backslash character. The corresponding adapter command is -PRESQL.
