When you choose to update statistics in your Maintenance Plan, and you have index on "computed column" in that database, the maintenance plan will fail with the following error: [Microsoft SQL-DMO (ODBC SQLState: 42000)] Error 1934: [Microsoft][ODBC SQL Server Driver][SQL Server]UPDATE STATISTICS failed because the following SET options have incorrect settings: 'QUOTED_IDENTIFIER'
Root Cause: Statistics can be created or updated on tables with computed columns only if the conditions (the following SET options) are such that an index can be created on these columns. All connections using indexes on computed columns or indexed views must have the same settings for these seven options. These six SET options must be set to ON: ANSI_NULLS ANSI_PADDING ANSI_WARNINGS ARITHABORT CONCAT_NULL_YIELDS_NULL QUOTED_IDENTIFIER The NUMERIC_ROUNDABORT option must be set to OFF. There is no way to set this option via the Maintenance plan which uses a separate connection and this is by design. This also happens if you create a simple SQL Agent job and run Update statistics. This is because, when you run a SQL Agent job, by default the SQL Server Agent does not set QUOTED_IDENTIFIER and this is required to be ON if you have an index on a computed column.
To Resolve this issue

SET ANSI_NULLS ON SET ANSI_PADDING ON
SET ANSI_WARNINGS ON SET ARITHABORT ON
SET CONCAT_NULL_YIELDS_NULL ON SET QUOTED_IDENTIFIER ON
SET NUMERIC_ROUNDABORT OFF
EXEC sp_MSForeachtable "UPDATE STATISTICS ? WITH FULLSCAN"
5. Click OK to save the steps.
