OracleHelpers comes with uppercase naming conventions for columns, tables and foreign keys. Also there is convention for properties of type string.
Install via NuGet:
PM> Install-Package EntityFramework.OracleHelpers
Add using to your DbContext class and apply conventions:
usingEntityFramework.OracleHelpers;protectedoverridevoidOnModelCreating(DbModelBuildermodelBuilder){this.ApplyAllConventionsIfOracle(modelBuilder);}That's it. One line and all default conventions will be applied if your connectionstring point to Oracle database.
OracleHelpers comes with following conventions:
- UpperCaseColumnNameConvention
- UpperCaseTableNameConvention
- UpperCaseForeignKeyNameConvention
- StringPropertyMaxLengthConvention
All UpperCase*NameConvention convert all names from default C# PascalCase to Oracle UpperCase. Basically from your class:
publicclassProduct{publicintId{get;set;}publicstringProductName{get;set;}publicDateTimeOnSaleFrom{get;set;}}You will get table:
| PRODUCTS |
|---|
| ID |
| PRODUCT_NAME |
| ON_SALE_FROM |
Note:
All UpperCase*NameConvention defaults to uppercase with underscore separated words but that can be overriden by constructor parameter.
As per Oracle documentation .NET Data Type String will be represented as Oracle NCLOB if MaxLength attribute is not set. StringPropertyMaxLengthConvention sets MaxLength to 2000 for all strings so you'll get NVARCHAR2(2000) column for your strings.
If needed you can override length per case if needed. So:
publicclassUser{publicintId{get;set;}publicstringFirstName{get;set;}[StringLength(100)]publicstringMiddleName{get;set;}[StringLength(7000)]publicstringLastName{get;set;}}Should look like this:
| USERS | TYPE |
|---|---|
| ID | |
| FIRST_NAME | NVARCHAR2(2000) |
| MIDDLE_NAME | NVARCHAR2(100) |
| LAST_NAME | NCLOB |
Apply all conventions with default values if ProviderInvariantName for current connection is Oracle.ManagedDataAccess.Client otherwise does nothing:
protectedoverridevoidOnModelCreating(DbModelBuildermodelBuilder){this.ApplyAllConventionsIfOracle(modelBuilder);base.OnModelCreating(modelBuilder);}You can check by yourself if on Oracle and apply some of conventions or change defaults:
protectedoverridevoidOnModelCreating(DbModelBuildermodelBuilder){if(this.IsOracle()){modelBuilder.ApplyAllUpperCaseConventions(convertToUnderscore:false);modelBuilder.ApplyStringMaxLengthConvention();}base.OnModelCreating(modelBuilder);}Ofcourse, you could apply those conventions even if you are not on Oracle database.
