What's New

v9.0.0.200
    � With this version, Code First support for Db2 for LUW and Db2 for zOS is included. v9.0.0.100 version had support for Database First.

v9.0.0.100
    � Support for Microsoft EF Core 9
    � Issue Fixes: The LINQ query may fail with SQL0104N error, when EF application uses table entities, configured with SMALLINT(2) data type against DB2 for z/os database. For example:
	    LINQ Query:
		    _dbContext.Smalltabs.Where(x =>x.IncnstDspstnNoted !=1);
	    Entity Configuration:
		    protected override void OnModelCreating(ModelBuilder modelBuilder)
            {
                modelBuilder.Entity<Smalltab>(entity =>
                {
                    entity
                    .HasNoKey()
                    .ToTable("SMALLTAB", "SCHEMA1");
                    entity.Property(e => e.IncnstDspstnNoted)
                    .HasColumnType("smallint(2)")  //this causes wrong SQL generation
                    .HasColumnName("INCNST_DSPSTN_NOTED");
                    entity.Property(e => e.ItemId)
                    .HasColumnType("bigint(8)")
                    .HasColumnName("ITEM_ID");
                });
            }
