CAPI3REF: Determine The Collation For a Virtual Table Constraint

This function may only be called from within a call to the [xBestIndex] method of a [virtual table].

The first argument must be the sqlite3_index_info object that is the first parameter to the xBestIndex() method. The second argument must be an index into the aConstraint[] array belonging to the sqlite3_index_info structure passed to xBestIndex. This function returns a pointer to a buffer containing the name of the collation sequence for the corresponding constraint.
