Every one of the columns in my resource table are varchars therefore when I developed my location table, I saw to it that they had the very same information kinds. So both tables have varchar information kinds for all columns.

Nevertheless, I am still obtaining the mistake: Column "col1" can not transform in between unicode and also non-unicode string information kinds. The unusual point is that if I change my OLE DB Location with a Trouble Web Location, it appears to function nevertheless, I wish to make use of OLE DB to ensure that I can defining points such as rows per set.

Can anybody aid?

Dual click the line in between the resource and also location as well as pick the Metal tab. That will certainly detail every one of your columns as well as the information kinds SSIS has actually presumed.

I would certainly contrast that to your resource as well as 100% guarantee they line up.

What can occur is that the very first time you developed your information circulation, SSIS will certainly establish the metadata based upon what the kinds go to that factor. col1 is translated to be nvarchar so it"ll established it as DT_WSTR of some size.

Time passes as well as you upgrade the resource and also the inquiry is currently varchar, yet still called col1. A varchar will certainly constantly suit an nvarchar so the form of that column hasn"t "transformed" so SSIS doesn"t demand to remodel it"s internals.

My click course is to [it is the situation that SSIS is sticking to old metadata [/p> Duplicate the existing queryChange my inquiry to pick 1 as TotallyNewAndUniqueColumnSSIS will certainly then report that all my metadata runs out whack as well as would certainly I such as to autofix it, as well as I click YesRepaste the initial inquiry as well as lo and also behold, the present metadata is recorded.
