我有一个具有这种结构的ArrayList或Vector
ArrayList = value1 value2 value3 value4 value5, value1_1 value2_1 value3_1 value4_1 value5_1, [...]
最多为value1_200(变量,但是此大小)。
我想在一列中插入每个值。我的数据库结构:
value1 VARCHAR, value2 VARCHAR, value3 VARCHAR, value4 VARCHAR, value5 VARCHAR
我应该使用BLOB
吗?如何将其插入SQLite数据库? (每个值集应该分成一行)
答案 0 :(得分:0)
自行解决,将ArrayList
转换为String
并使用此方法插入。
int init = 0;
for(int t = init; t < arr.length; t++){
Log.i(TAG, "arr["+t+"] = " + arr[t].trim());
if(r == 1) {
database.execSQL("INSERT INTO table (id) VALUES ('" + arr[t].trim() + "')");
id_save = arr[t].trim();
r++;
}else if(r == 2) {
database.execSQL("UPDATE table SET name='" + arr[t].trim() + "' WHERE id='" + id_save + "'");
name_save = arr[t].trim();
r++;
}else if(r == 3) {
database.execSQL("UPDATE table SET weburl='" + arr[t].trim() + "' WHERE id='" + id_save + "' AND name='" + name_save + "'");
r++;
}else if(r == 4) {
database.execSQL("UPDATE tables SET mainurl='" + arr[t].trim() + "' WHERE id='" + id_save + "' AND name='" + name_save + "'");
r++;
}else if(r == 5) {
database.execSQL("UPDATE table SET logo='" + arr[t].trim() + "' WHERE id='" + id_save + "' AND name='" + name_save + "'");
r = 1;
}
