Dears,
Recently I have created a mail merge document using sources from here, worked like charm -> I've created over 2k+ docs in an hour.
But, then something happened, office or op-system update and now the where clause stops the whole procedure -> I've become very confused about this case.


Q: is there any way to replace my excel files as datasources to eg text file, either csv or rich text or any other offfice supported?
Q: what can cause this issue as if I use a simple select field1, field2, etc or I simply put select * to the statement, works like charm....
Once I start the where clause it displays an error message that missing parameter or can not connect to datasource or invalid function... Very-very-confused


Any hints or idea?
Thanks in advance!
