使用EzApi创建SSIS包

我使用EzApi创建SSIS包。但是,我无法创建具有多个源和单个目标的包。例如,两个OLEDB源和单个OLEDB目的地。 我想知道的是如何使用c#代码添加合并转换。 请帮忙

EzApi 中有一个名为EzMerge的组件 如果需要创建自定义数据流 - 可以使用名为EzDataFlowPackage的基类:

class MyPackage: EzDataFlowPackage
{
        public EzOleDbSource src1;
        public EzOleDbSource src2;
        public EzMerge merge;
        public EzOleDbDest dest;
        public EzOleDbConnectionManager srcConnMgr1;
        public EzOleDbConnectionManager srcConnMgr2;
        public EzOleDbConnectionManager destConnMgr;


        public EzMyPackage() : base() 
        {
            srcConnMgr1 = new EzOleDbConnectionManager(this);
            srcConnMgr2 = new EzOleDbConnectionManager(this);
            src1 = new EzOleDbSource(DataFlow);
            src2 = new EzOleDbSource(DataFlow);
            dest mew EzOleDbDest(DataFlow);
            src1.Connection = srcConnMgr1;
            src2.Connection = srcConnMgr2;
            dest.Connection = destConnMgr;
            merge = new EzMerge(DataFlow);
            src1.AttachTo(merge);
            src2.AttachTo(merge);
            merge.AttachTo(dest);
        }

        public EzMyPackage(Package p) : base(p) { }

        public static implicit operator EzMyPackage(Package p) { return new EzMyPackage(p); }
}

我刚输入此代码 - 因此可能包含错误。在此之后,您的包布局已准备就绪。您只需设置组件属性即可。

我没有使用EzApi,但是在BIDS(Visual Studio)中,您需要有两个数据源,一个数据目标和一个“合并”组件来连接它:

像这样:

关于装箱是有道理的。请查看以下链接:

在评论//create the Merge Transformation

之后查找代码
//create the Merge Transformation
IDTSComponentMetaData90 merge = dataflow.ComponentMetaDataCollection.New();
merge.ComponentClassID = "DTSTransform.MergeJoin";
CManagedComponentWrapper mergeDesigntime = merge.Instantiate();
mergeDesigntime.ProvideComponentProperties();
merge.Name = "Merge Source1 and source2";
Console.WriteLine("merge created ");
merge.InputCollection[0].ExternalMetadataColumnCollection.IsUsed = false;
merge.InputCollection[0].HasSideEffects = false;
merge.InputCollection[1].ExternalMetadataColumnCollection.IsUsed = false;
merge.InputCollection[1].HasSideEffects = false;

//create path from source1 to merge
/*More code - see article*/

//create path from source2 to merge
/*More code - see article*/
