You should use Lookup active not Get Metadata active.
According you problem,, please follow this workaround:
<ol>
<li>Using <a href="https://learn.microsoft.com/en-us/azure/data-factory/control-flow-lookup-activity" rel="nofollow noreferrer">Lookup active</a> to get the content of the table <code>Metadata</code>.
<a href="https://i.stack.imgur.com/xc7To.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xc7To.png" alt="enter image description here" /></a></li>
<li>For each active to loop the each row of <code>Metadata</code>:
<a href="https://i.stack.imgur.com/CoqQt.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CoqQt.png" alt="enter image description here" /></a></li>
<li>Foreach inner actives, create the copy active which source and sink
all set with foreach item. For example:
<a href="https://i.stack.imgur.com/RLRgn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RLRgn.png" alt="enter image description here" /></a>
<a href="https://i.stack.imgur.com/wlrPr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wlrPr.png" alt="enter image description here" /></a></li>
</ol>
HTH.

I have 4 SQL tables.
<ol>
<li>Employee(which contains employee information)</li>
<li>Engineers( same structure as EMployee but no input)</li>
</ol>
3)Student( same structure as EMployee but no input)
4)Metadata ( contains the source and destination information such as source: Employee destination: Student)
My goal is to create an ADF pipeline that will fetch metadata table information (source and destination) and will perform copy activity from the source to destination as per data in the Metadata table.
Employee Table
<a href="https://i.stack.imgur.com/Kw3wX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Kw3wX.png" alt="enter image description here" /></a>
Metadata Table
<a href="https://i.stack.imgur.com/nIpYl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nIpYl.png" alt="Flag Source destination
2 dbo.Employee dbo.Engineer" /></a>
Engineer Table
<a href="https://i.stack.imgur.com/6F65P.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6F65P.png" alt="ID First_name Last_name" /></a>
I want my ADF pipeline to fetch the source and destination data from Metadata table and perform copy activity from source to destination as per mentioned in Metadata table.
I have tried the below approaches but not succeeded yet.
getMetadata---&gt; copyActivity [ not able to fetch the metadata table data]
getmetadata---&gt;foreach loop----&gt; copy activity [ again for able to fetch the data]

I want to fetch Azure SQL table data from ADF to use as input in copy activity

我有4个SQL表。雇员(其中包含员工信息)工程师(与EMployee结构相同，但没有输入)3)学生(与EMployee相同的结构，但没有输入)4)元数据(包含源和目标信息，如来源:雇员目的地:学生)我的目标是创建一个ADF管道，该管道将获取元数据表信息(源和目标)，并按照元数据表中的数据执行从源到目的地的复制活动。员工表​​元数据表​​工程师表​​我希望我的ADF管道从元数据表中获取源数据和目标数
