variable in DCT and SQLserver

hi

One of my programs is checking in a SQLServer database, a recordset containing a lot of double lines to remove.

in order to avoid to do the parsing in my LabView code,  I began to try to remove them directly by SQLserver request. this request contains table variables. unfortunately, the recordset is returning zero values (wherehas it works in SQLserver directly OR from labview without variables)

I realized by creating the little code I send you joined (LV2015) that the SQL variable are simply not recognized when using the DCT.

is there a solution to make them useable? did I lose my time by working with something not compatible?

thanks in advance for your help
