[Pkg-tcltk-devel] tclodbc off-by-one error

[Sergei Golovan]

Hi, Massimo, Christian,

As far as I can see in the code, the parameter index is calculated as
i+1 from the loop variable i:

for (i = 0; i < nParams; ++i) {
    rc = SQLDescribeParam(sdata->hStmt, i+1,
...

Can you be more specific in which query fails and how?
