Argument error; the number of columns does not equal the number of parameters.

Question

I am using the Database Toolkit (Enterprise Connectivity) to check for a network connection and then send information from a local database to a SQL database on the network if needed.  In development of the code I continue to receive Error 1 and the Possible Reason(s) is "Argument error; the number of columns does not equal the number of parameters."  I am using the DBToolsSelectData.VI to retrieve data from the local MDB file and the DBToolsInsertData.VI to write it to the SQL file.  The collection of the data from the MDB file is successful and the connection and validation of the table and columns in the SQL file is also successful.  The error occurs when the Insert VI tries to build the query.  The number of columns being written (attempted) does match the number of columns in the data, they are both 16 string arrays.

Answer 1

Ok, it's taken a bit, and I have a solution! It took a while to figure out what the DCT is doing, but it seems to be working now.
The reason for the original error is that you were passing into the insert subVI an array of variants - which the input to the VI coerced into a single variant. You were getting the error because as far as the insert VI was concerned you were only passing it a single data value. The way to get around that was to create a cluster with one element for each column value, convert the cluster to a variant and pass the result to the insert VI - see attachment.
In terms of the other modifications, I made a copy of the endurance.mdb file, emptied it and used it as the destination for the copy.
