This section describes the default number mapping behavior and how to customize it for your application. You can configure a custom mapping in the .NET configuration file to override the default mapping for each Oracle NUMBER(p,0), which represents integer values.

Oracle NUMBER data types that represent integers do not have a matching .NET integer data type with exactly the same range of acceptable values. ODP.NET uses a default mapping that ensures any .NET integer type values can be stored within the Oracle database without requiring custom data type mapping. However, it is possible that Oracle NUMBER(p,0) column data can be larger than what a .NET data type can hold when retrieving values from the database.

Org.hibernate.dialect.OracleDialect does not support identity key generation. Does not support identity key generation at org.hibernate.dialect.Dialect. Org.hibernate.dialect.Oracle10gDialect does not support identity key generation.

Oracle identity column restrictions. The identity columns are subject to the following restrictions: Each table has one and only one identity column. The data type of the identity column must be a numeric data type. The user-defined data type is not allowed to use with the identity clause. Q&A for Work. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Identityclause Use identityclause to modify the properties of an identity column. You cannot specify this clause on a column that is not an identity column. If you do not specify ALWAYS or BY DEFAULT, then the current generation type is retained. Refer to CREATE TABLE identityclause for more information on ALWAYS and BY DEFAULT.

For example, in Entity Framework 6, Oracle NUMBER(3,0) has a default mapping to .NET Byte. Oracle NUMBER(3,0) can store a value up to 999, while a .NET BYTE can store up to the value of 255. If you expect the Oracle data to exceed 255, modify the mapping to a larger numeric data type, such as a .NET Int16. Setting up this custom mapping allows you to consume the data in .NET without encountering an error. When such a custom mapping is used, be cautious not to insert a .NET Int16 value beyond what an Oracle NUMBER(3,0) column can hold. Trying to insert Int16.MaxValue (i.e. 32,767) into a NUMBER(3,0) column will cause an Oracle Database error.

4.4.1 Entity Framework 5 and Earlier Mapping and Customization

Example 4-1 shows an ODP.NET, Unmanaged Driver sample app.config file that uses custom mapping to map the Number(1,0) Oracle data type to the bool EDM type. For example, Number(1,0), which is mapped to Int16 by default, can be custom mapped to the .NET Bool or .NET Byte type. This example maps Number(3,0) to byte, and sets the maximum precisions for the Int16, Int32, and Int64 data types to 4, 9, and 18 respectively.

Example 4-2 shows the same changes as Example 4-1, but using the traditional ODP.NET, Unmanaged Driver app.config format.

Example 4-3 shows a ODP.NET, Managed Driver sample app.config file.

Example 4-1, Example 4-2, and Example 4-3 customizes the mappings as follows:

Custom mapping configures the maximum precision of the Oracle Number type that would map to the .NET/EDM type. So, for example, the preceding custom application configuration file configures ODP.NET to map Number(10,0) through Number(18,0) to Int64, as opposed to the default range of Number(11,0) through Number(19,0) for Int64.

Note:

• Custom mapping does not require you to map all the .NET/EDM types. For example, if custom mapping is required just for Int16, then having a single entry for Int16 is sufficient. Default mapping gets used for the other types.

• When using Model First, a Byte attribute is mapped to Number(3,0) by default. However, when a model is generated for a Number(3,0) column, it gets mapped to Int16 by default unless custom mapping for Byte is specified.

You must make sure that your mappings allow the data to fit within the range of the .NET/EDM type and the Number(p, s) type. If you select a .NET/EDM type with a range too small for the Oracle Number data, then errors will occur during data retrieval. Also, if you select a .NET/EDM type, and the corresponding data is too big for the Oracle Number column, then INSERTs and UPDATEs to the Oracle database will error out.

Example 4-1 First Sample ODP.NET, Unmanaged Driver Application Configuration File to Custom Map the Number (p,0) Data Type

Example 4-2 Second Sample ODP.NET, Unmanaged Driver Application Configuration File to Custom Map the Number (p,0) Data Type

Example 4-3 Sample ODP.NET, Managed Driver Application Configuration File to Custom Map the Number Data Type

4.4.2 Entity Framework 6 Mapping and Customization

ODP.NET 12.1.0.2 introduces a new .NET configuration setting format for both managed and unmanaged ODP.NET. This new setting format applies only for use with Entity Framework 6 and Entity Data Model mappings, including Code First, Database First, and Model First use cases. Developers can continue using the existing ODP.NET format for non-Entity Framework 6 applications.

This new format unifies how ODP.NET, Managed and Unmanaged Drivers sets their configuration values and supports auto-completion.

The following is an example of an edmMappings section for ODP.NET, Managed Driver:

Where:

• DBType is the Oracle Database data type

• NETType is the .NET data type that the Oracle data type maps to

• MinPrecision is the minimum range the Oracle data type will map to the .NET type

• MaxPrecision is the maximum range the Oracle data type will map to the .NET type

The following is an example of an edmmappings section for ODP.NET, Unmanaged Driver. It is exactly same format as the managed driver with the exception of the opening and closing tags.

4.4.2.1 New Default Mappings

For Entity Framework 6, ODP.NET 12.1.0.2 introduces new default mappings that apply to Code First, Database First, and Model First scenarios. These changes were necessary to support Code First interoperability.

• .NET Booleans map to Oracle Number(1,0) and vice-versa by default

• .NET Bytes map to Oracle Number(2,0) and Number(3,0) and vice-versa by default

This default behavior can be changed by providing an alternative data type mapping by configuring the section of the .NET config file.

4.4.3 Data Type Mapping and Customization Process

To enable custom mapping, add the mapping information to the .NET config file prior to EDM creation.

If the EDM was created already before providing the mapping information, then you can modify the mappings either through the Visual Studio tools or manually. Using Visual Studio, go to the EDM Model Browser page. Right-click on the table(s) requiring new data type mapping and select Table Mapping from the pop-up menu. The Mapping Details window will appear usually at the bottom of your screen. Update Column Mappings as desired.

If you need to add or delete mappings, find the Type values in the CSDL mapping section of your project's existing EDMX file. Add or delete those Type values to the .NET data types you want the application to use. In the example below, the property name types for BOOLCOL and BYTECOL are added to the CSDL and mapped to Boolean and Byte, respectively.

Example Mapping Before CSDL Customization:

Example Mapping After CSDL Customization: /days-gone-cd-key-serial-generator.html.

You can employ combinations of these customization possibilities depending on your planned mapping changes. If many tables and many columns require mapping changes, it is most efficient to delete the EDMX file and regenerate the data model. If a few tables and many columns require changes, then delete the affected tables, save the EDMX file, and select Update Model from Database.. to include those tables again. If only a single table and one or two columns require changes, then modify the EDMX either manually or by using the Mapping Details window.

Note:

When using the EDM wizard to create a complex type from a function import, any custom EDM type mappings specified will not be applied automatically. The EDM wizard uses the default type mappings. Developers must then manually edit the resulting complex type. Developers begin this process after the complex type is generated. Any type declaration (field, property, constructor parameter, etc.) in the complex object which has an undesired type mapping, such as Decimal rather than Boolean, should be manually edited to the desired type.

4.4.4 StoreGeneratedPattern Enumeration

The following sections describe the Identity attribute and the Virtual column.

4.4.4.1 Identity Attribute

Oracle Database 12c (12.1) and later versions support table or view Identity attribute columns. Oracle has three Identity attribute types. When the EDM wizard generates a data model from an Oracle Identity attribute-containing table or view, ODP.NET will set the value of StoreGeneratedPattern to Identity in the .edmx file for any of three Oracle Identity types. The Identity attribute-associated column will use the server-generated value during INSERT: hence, application developers no longer need to create a sequence nor trigger. If the .NET application attempts to set the Identity attribute itself, this value will be ignored.

For Oracle Database 11g Release 2 (11.2) and earlier versions that do not support Identity columns, application developers can manually set StoreGeneratedPattern to Identity in columns through the entity model designer Properties after model generation, then create an INSERT trigger. Depending on the data type, a sequence may not be necessary if a server function, such as sys_guid(), can generate the value for the column.

4.4.4.2 Virtual Column

Oracle Database 11g (11.1) and later versions can store expressions directly in base tables as Virtual columns, also known as Generated columns. Virtual columns cannot be inserted into or updated. ODP.NET will not automatically set StoreGeneratedPattern to Computed in the EF model for Virtual columns. To avoid errors, application developers need to add or change the value of StoreGeneratedPattern to Computed for Virtual columns after the model generation. Once done, Virtual columns are excluded from INSERTs and UPDATEs upon calling SaveChanges().

4.4.5 Resolving Compilation Errors When Using Custom Mapping

If the custom mapping in a .NET configuration file has changed, then regenerate the data model to solve compilation errors introduced by the changes.

Under certain scenarios, custom mapping may cause compilation errors when a project that uses custom mapping is loaded by Visual Studio. One specific scenario is when Visual Studio opens a project with an existing custom mapping that now generates errors when those errors did not exist before. You may use the following workaround for such scenarios:

1. Open Visual Studio Help, About Microsoft Visual Studio. Click OK to exit the dialog box.

   Alternatively, open the to-be-used connection in Server Explorer.

2. Compile the project again to eliminate the compilation errors.

4.4.6 Mapping Boolean and Guid Parameters in Custom INSERT, UPDATE, and DELETE Stored Procedures

When using your custom INSERT, UPDATE, or DELETE stored procedure in Stored Procedure Mapping, the following error might occur:

Error 2042: Parameter Mapping specified is not valid.

This can happen if a Number parameter has been mapped to a Boolean attribute, or if a RAW parameter has been mapped to a Guid attribute.

The solution is to manually add Precision='1' for the Number parameter, and MaxLength='16' for the RAW parameter of your stored procedure in the SSDL.
