+** This function constructs and returns a pointer to a nul-terminated
+** string containing some SQL clause or list based on one or more of the
+** column names currently stored in the pIter->azTblCol[] array.
+**
+** If an OOM error is encountered, NULL is returned and an error code
+** left in the OTA handle passed as the first argument. Otherwise, a pointer
+** to the allocated string buffer is returned. It is the responsibility
+** of the caller to eventually free this buffer using sqlite3_free().
+**
+** The number of column names to include in the returned string is passed
+** as the third argument.
+**
+** If arguments aiCol and azCollate are both NULL, then the returned string
+** contains the first nCol column names as a comma-separated list. For
+** example:
+**
+** "a", "b", "c"
+**
+** If argument aiCol is not NULL, it must point to an array containing nCol
+** entries - the index of each column name to include in the comma-separated
+** list. For example, if aiCol[] contains {2, 0, 1), then the returned
+** string is changed to:
+**
+** "c", "a", "b"
+**
+** If azCollate is not NULL, it must also point to an array containing nCol
+** entries - collation sequence names to associated with each element of
+** the comma separated list. For example, ef azCollate[] contains
+** {"BINARY", "NOCASE", "REVERSE"}, then the retuned string is:
+**
+** "c" COLLATE "BINARY", "a" COLLATE "NOCASE", "b" COLLATE "REVERSE"
