Sybase ASE 15: User data types mapped to java Object type [message #793215] Tue, 07 February 2012 17:23 Go to next message

Hi,
Is there a type mapping file somewhere for Sybase ASE? We have numerous custom data types ('ut_sysgen', for example, which is 'int'). Dali just makes them Object types when generating entities from tables.

I am using Indigo. I tried updating Sybase_ASE_15.x.xmi in org.eclipse.datatools.enablement.sybase.ase.dbdefinition_1.0.0.v200906161800.jar
by adding '<name>ut_sysgen</name>' in the element with INT and INTEGER, but it didn't pick it up there, maybe something to do with jdbcEnumType being different for a custom type, I don't know.

I know updating that file does something as I tried mucking with the Java types for other db types and it did change the code that was generated.

Any hints on where to configure this type mapping?

Thanks, Patrick

Patrick:

It sounds like you are headed in the right direction. This is more of a question for DTP[1]; since Dali just uses the DTP API. But here's some additional information that might help:

To derive the appropriate Java type declaration for generated fields, Dali use the DTP API as follows:

Dali calls
o.e.datatools.modelbase.sql.tables.Column.getDateType()

(implemented in ...schema.TypedElement) which returns a ...datatypes.DataType.

If this DataType is an instance of PredefinedDataType, Dali passes its name to
o.e.datatools.connectivity.sqm.core.definition.DatabaseDefinition.getPredefinedDataTypeDefinition(String)

which returns a ...dbdefinition.PredefinedDataTypeDefinition.

PredefinedDataTypeDefinition.getJavaClassName() returns a Java class name that Dali can then use in the code generation.

Maybe you can use this information to ask the appropriate questions of DTP.
