Android开发判断SQLite数据库中某个表是否存在
直接上方法:
public boolean tabIsExist(SQLiteDatabase db){
boolean result = false;
if(yourTableName == null){
return false;
}
Cursor cursor = null;
try {
String sql = "select count(*) as c from sqlite_master where type ='table' and name ='"+yourTableName.trim()+"' ";
cursor = db.rawQuery(sql, null);
if(cursor.moveToNext()){
int count = cursor.getInt(0);
if(count>0){
result = true;
}
}
} catch (Exception e) {
}
return result;
