SSIS Passing Parameters to an ADO .NET Source query; pass parameters to the ado.net data source.

The parameter buttons when using SSIS's oledb data source are as follows:

But when using ADO.NET source to connect to MYSQL, without this parameter button, how to pass parameters to the sql command of the data stream?

steps:

1. On the Control Flow tab, right-click on the data flow task containing the ado.net source and select Properties-> Set Expressions.

2. Set as follows in the property expression editor:

Properties: Select ADO.NET source.SQLCommand. Note that the ADO.NET source is the name of the ado.net source. If you have changed the component name, this is your custom name. sqlcommand.

Expression: Click the button at the back, fill in your sql statement and the value passed from the variable and parameter, which is @ [User :: PV_WaterMarkValue] in this example, and then click the calculation expression Button:

Note: The method of string concatenation is used, pay attention to "" and "'.

My example here is:

"select cast(date_format(orderdate,'%Y%m%d') as signed) as datekey,`order`.*, branchoffice.BranchOfficeName from `order` inner join branchoffice on `order`.BranchOfficeSN=branchoffice.BranchOfficeSN where `order`.orderdate >'"+ @[User::PV_WaterMarkValue]+"'"

In this way, the ado.net source in the Data flow task gets the value returned from Get Water Mark.

By the way, demonstrate how the value in Get Water Mark is returned:

1. Define variables

2. Assign values to variables

3. Set the result set
