If a workflow failure occurs using one database profile, a failover process starts to replace that profile with the next available one. If none of the supplied profiles could be used a null value will be returned.

All functions without the parameter disableCommit=false will not be auto commit after the function has executed.

Note

title	Note!

Failovers can be triggered by all errors that occur while connecting to the database or executing commands, not exclusively due to connection problems.

Please refer to Notes section on the Database Functions page for details on allowed database data type.

Parameter Description

sqlStatement

SQL string containing one or more parameter placeholders ('?').

parameter(s)

Value(s) to bind against parameter placeholders.

DBProfile/s)

Name of the database profile(s) to use for access.

disableCommit

An optional parameter to disable the commit statement from being performed at the end of every SQL transaction for this particular function. Setting this parameter to false will result in the commit statement to be performed at the end of every SQL transaction for this particular function. By default, the system has the disableCommit set to true unless changed by this parameter.

Info
It should be noted that on recent Oracle versions, the DBLink SQL transaction behaviour has changed, where every single SQL statement for remote database transaction requires a commit or rollback statement in order to close a connection.

Returns

Null in case of failure the error details can be found in System Log, otherwise a table, holding the SQL select result.
