Unsupported DBI methods — DBI-custom

Most pool methods for DBI generics check out a connection, perform the operation, and the return the connection to the pool, as described in DBI-wrap. This page describes the exceptions: DBI::dbSendQuery() and DBI::dbSendStatement() can't work with pool because they return result sets that are bound to a specific connection. Instead use DBI::dbGetQuery(), DBI::dbExecute(), or localCheckout(). DBI::dbBegin(), DBI::dbRollback(), DBI::dbCommit(), and DBI::dbWithTransaction() can't work with pool because transactions are bound to a connection. Instead use poolWithTransaction(). DBI::dbDisconnect() can't work because pool handles disconnection. Use poolClose() instead. DBI::dbGetInfo() returns information about the pool, not the database connection. DBI::dbIsValid() returns whether or not the entire pool is valid (i.e. not closed).
