我創建的表沒有主鍵更新一列有主鍵
像這樣:
private static final String SCRIPT_CREATE_DATABASE =
"create table " + MYDATABASE_TABLE + " ("
+ KEY_ID + " INT, "
+ KEY_CONTENT1 + " , "
+ KEY_CONTENT2 + " , " + KEY_CONTENT3 +" date, " + KEY_CONTENT4 +
" , " + KEY_CONTENT5 +
" , " + KEY_CONTENT6 +
" , " + KEY_CONTENT7 +
" , " + KEY_CONTENT8 +
" , " + KEY_CONTENT9 +
" , " + KEY_CONTENT10 +
" , " + KEY_CONTENT11 +
" , " + KEY_CONTENT12 +
" , " + KEY_CONTENT13 +
");";
,但我想更新的行KEY_ID應該有主鍵,在表中有沒有主鍵創建,我可以更新表嗎?,請幫助。
