我使用SQLite（3.7.5版本），在http://www.xerial.org/trac/Xerial/wiki/SQLiteJDBCsqlite的setBytes（）不工作的BLOB數據類型在Windows
提供sqlite的jdbc驅動我問了一個幾乎相同的問題，幾個月前，在xerial論壇（HTTP ：//groups.google.com/group/xerial/browse_thread/thread/ee19bd855e282f9c），但從來沒有得到任何迴應。
當我自己構建共享庫sqlite.dll/libsqlite.so時，我的示例在Linux上運行正常（opensuse 64位），但在Windows XP Professional 32位上無法正常工作。
但是，如果我使用sqlite.org網站提供的共享庫（http://sqlite.org/sqlite-dll-win32-x86-3070500.zip）或與jdbc驅動程序捆綁在一起的共享庫（http://www.xerial.org/maven/repository/artifact/org/xerial/sqlite-jdbc/3.7.2/sqlite-jdbc-3.7.2.jar），它可以在Linux和Windows上正常工作。
因此，我猜測我沒有正確構建sqlite庫。我正在使用Microsoft Platform SDK的cygwin環境來構建sqlite。我正在使用以下一組命令在Windows XP 32位上創建sqlite庫。
mycl -32 -O2/d 「NDEBUG」/ MD/d 「_WIN32」/ d 「_WINDOWS」/ d 「_MBCS」/ d 「_USRDLL」/ d 「SQLITE_ENABLE_COLUMN_METADATA」/ d 「SQLITE_ENABLE_FTS3」/ d「SQLITE_THREADSAFE = 1「-c NativeDB.c -o NativeDB.o
mycl -32 -O2/D」NDEBUG「/ MD/D」_WIN32「/ D」_WINDOWS「/ D」_MBCS「/ D」_USRDLL「/ d 「SQLITE_ENABLE_COLUMN_METADATA」/ d 「SQLITE_ENABLE_FTS3」/ d 「SQLITE_THREADSAFE = 1」 -c sqlite3.c -o sqlite3.o
myLink的-32/DLL /libpath:../lib/Win32 /out:sqlite.dll NativeDB.o sqlite3.o gdi32.lib vfw32.lib user32.lib comdlg32.lib comctl32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib wbemuuid.lib netapi32.lib ws2_32.lib kernel32.lib
mymt -32 /清單sqlite.dll.manifest /outputresource:sqlite.dll';#2'
（mycl，myLink的，和mymt是圍繞原始cl.exe時，LINK.EXE，和mt包裝.exe轉換命令行參數。他們與我一起構建的許多其他項目都能很好地工作）。
我也創建了一個SSCE來演示這個問題。

我也試圖建立與源碼ICU的Unicode庫（4.4.2版本）。我正在使用以下命令來構建帶有unicode支持的sqlite。
cl.exe時-32 -O2/d 「NDEBUG」/ MD/d 「_WIN32」/ d 「_WINDOWS」/ d 「_MBCS」/ d 「_USRDLL」/ d 「SQLITE_ENABLE_COLUMN_METADATA」/ d 「SQLITE_ENABLE_FTS3」/ d 「SQLITE_THREADSAFE = 1」/ D「SQLITE_ENABLE_ICU」-I ../ external/icu/win32/include -I ../ include -c NativeDB.c -o NativeDB.o
cl.exe -32 -O2/D「NDEBUG」/ MD/D「_WIN32」/ D「_WINDOWS」/ D「_MBCS」/ D「_USRDLL」/ D「SQLITE_ENABLE_COLUMN_METADATA」/ D「SQLITE_ENABLE_FTS3」/ D「SQLITE_THREADSAFE = 1」/ D「SQLITE_ENABLE_ICU」 ../external/icu/win32/include -I ../ include -c sqlite3.c -o sqlite3.o

樓內有/無Unicode有沒有效果。我仍然無法解決問題。我將非常感謝任何幫助或指向可能的解決方案/解決方法。
