Cannot show the editor for this task.

I got this error in SSIS when I try to open Execute SQL Task.



Then I tried to open already configured Execute SQL Task in some other SSIS packages. Still the error exists. I was wondering this is an error in SQL Server 2014 so I installed SQL Server 2012 and tried but it was no difference.

So the work around is by clicking F4 and enter the configuration values in the Properties box.

Difference Between LEN and DATALENGTH

DATALENGTH - Returns the number of bytes used to represent any expression.

LEN - Returns the number of characters of the specified string expression, excluding trailing blanks


Output is 30, 3.

Important point to remember is is LEN function does not depend on the data type and it is storage mechanism. LEN function total depends on the number of string characters.


Output is 8 and 3.

So DATALENGTH is depends on the storage but not the LEN function.
