If you can insert those characters via mgmt console the columns should presumably be of type nvarchar
.
To insert your data via script you need to mark your string input values als unicode by prefixing them with N
:
N'Flüssigkeitsbilanz (24 Stunden)'
Your sample insert statement should look like this:
insert into @ReportGruppe1 values(507,'ID_507', N'Flüssigkeitsbilanz (24 Stunden)', N'CC_1_LeerVordrucke_A4_Hoch.lst', 'AP;PP', 1, 10, 1)
Check the data types of your columns and handle input for those accepting nvarchar
(or nchar
and other unicode types) accordingly.
