public InputStream getLOBStream(JDBCStore store, ResultSet rs, int column) throws SQLException
InputStream
by using ResultSet.getBlob(int)
and
Blob.getBinaryStream()
.
Unfortunately this will load entire BLOB into memory.
The alternative ResultSet.getBinaryStream(int)
provides true streaming but
the stream can be consumed only as long as ResultSet
is open.

Unfortunately this will load entire CLOB into memory.

provides true streaming but
the stream can be consumed only as long as ResultSet

indexOf

buf
- the SQL buffer to write the indexOf invocation tostr
- a query value representing the target stringfind
- a query value representing the search stringstart
- a query value representing the start index, or null
to start at the beginning
