Can we return multiple ports in unconnected lookup?
Hi, Using unconnected lookup, you can return only one port.
How do I return multiple ports in a single unconnected lookup?
You can’t return multiple ports from unconnected lookup. Unconnceted lookup always returns single port. You can instead use connected lookup for multiple ports.
How do I get multiple outputs from unconnected lookups?
Call the Unconnected lookup from the expression transformation and use various output ports to retrieve the lookup values based on the concatenated return value. Use SUBSTR,INSTR to extract the column values from the concatenated return field.
Can a connected lookup return multiple records?
Since Lookup is a passive ,it is not possible to return multiple rows …
How many ports can we return from a connected lookup transformation?
A lookup transformation configured as an Unconnected Lookup can only return one port.
Can you enable dynamic cache for a lookup transformation that returns multiple rows?
You cannot use dynamic cache for Lookup transformation that returns multiple rows. You cannot return multiple rows from an unconnected Lookup transformation.
Can I VLOOKUP multiple values?
An immediate solution that comes to mind is using the Excel VLOOKUP function, but the problem is that it can only return a single match. Vlookup for multiple values can be done via a combined use of several functions.
Why unconnected lookup is not dynamic?
The primary purpose of Unconnected lookup is to be called for the lookup value multiple time based on the need and it is not a direct link to the mapping flow It is, just like a variable defined in an Expression transformation.
Which port is used to return a port from unconnected lookup?
Lookup port : The designer designates each column of the lookup source as lookup port. Return port : An unconnected lookup transformation has one return port that returns one column of data to the calling transformation through this port.
Can unconnected lookup use dynamic cache?
Unconnected Lookup Does Not Support Dynamic Cache.
How do I do a VLOOKUP with multiple entries?
To lookup multiple matches with the VLOOKUP Function you need to create a helper column within the table of data. The helper column uses the COUNTIF Function to create a unique ID for each instance. The helper column must be the leftmost column within the data set.
Why unconnected lookup is faster?
Unconnected Lookup is always better.. It takes less time as compared to that of Connected Lookup. Because Unconnected Transformation is Isolated within the mapping,we can call this lookup with the help of a Expression transformation. Where as connected loopup is connected in a single pipeline from source to target.
Can we use dynamic cache with unconnected lookup?
What is difference between connected and unconnected lookups in Informatica?
Connected lookup receives input values directly from mapping pipeline, whereas UnConnected lookup receives values from the lookup expression from another transformation. A mapping in Informatica may contain Source, Transformations and Targets connected together are considered as a pipeline.
