.NET Mapping In entity framework, converting a Boolean datatype to an Oracle number(1,0) causes an error.
.net entity-framework
Question
The following error is thrown when a.NET boolean datatype is mapped to an Oracle number(1,0) in an.edmx file.
Error 2019: Member Mapping specified is not valid. The type 'Edm.Boolean[Nullable=False,DefaultValue=]' of member 'COLUMN123' in type 'DBModel.TABLE123' is not compatible with 'OracleEFProvider.number[Nullable=False,DefaultValue=,Precision=1,Scale=0]' of member 'CHECK_INSTALLATION' in type 'DBModel.Store.TABLE123'.
Can an entity framework transfer a boolean datatype to Oracle's number(1,0)?
Popular Answer
I found that just adding an oracle.dataaccess.client section wasn't enough. The following did work (taken from Setting up and configuring ODP.NET to use Entity Framework without installation):
<configuration>
<configSections>
<section name="oracle.dataaccess.client" type="System.Data.Common.DbProviderConfigurationHandler, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
</configSections>
...
<oracle.dataaccess.client>
<settings>
<add name="bool" value="edmmapping number(1,0)" />
</settings>
</oracle.dataaccess.client>
<oracle.manageddataaccess.client>
<version number="*">
<edmMappings>
<edmMapping dataType="number">
<add name="bool" precision="1"/>
<add name="byte" precision="2" />
<add name="int16" precision="5" />
</edmMapping>
</edmMappings>
</version>
</oracle.manageddataaccess.client>
