![]() ![]() These entity types map to the following tables when using SQL Server or Azure SQL. Note that using DateTimeOffset would not help here, since opening and closing times have different offsets depending whether daylight saving time is active or not. Handling different timezones would complicate this code significantly. This model represents only British schools and stores times as local (GMT) times. The code shown here comes from DateOnlyTimeOnlySample.cs. SqlQuery can be used to query this table and return instances of a BlogPost type with properties corresponding to the columns in the table: For example, consider the following database table: CREATE TABLE ( The former uses string interpolation to parameterize the query, which helps ensure that all non-constant values are parameterized. Queries using unmapped types are executed using SqlQuery or SqlQueryRaw. The code shown here comes from RawSqlSample.cs. This is enhanced in EF8 to include raw SQL queries returning any mappable CLR type, without including that type in the EF model. Raw SQL queries for unmapped typesĮF7 introduced raw SQL queries returning scalar types. All the code is available in runnable samples on GitHub. In total, EF8 preview 1 ships with more than 60 improvements, both bug fixes and enhancements.įull details of all new EF8 features can be found in the What’s New in EF8 documentation. The following sections give an overview of three particular enhancements available in EF8 preview 1: Raw SQL queries for unmapped types, lazy-loading for no-tracking queries, and DateOnly/ TimeOnly support for SQL Server/Azure SQL. This data will then feed into the planning process for the next release. The best way to indicate the importance of an issue is to vote (□) for that issue on GitHub.
