How to DELETE a row with a GUID Value in SQLite

问题

I have a column in SQLite of GUID type, I have tried a query like this, and it returns no error, but the row is not deleted

DELETE FROM MyTable WHERE Id='4ffbd580-b17d-4731-b162-ede8d698e026';

In SQLite Browser the Id values look like binary values, they have strange characters.

I also have tried this, but still does not work

DELETE FROM MyTable WHERE Id='{4ffbd580-b17d-4731-b162-ede8d698e026}';

回答1:

Try this command. Id is a probably a binary blob field

 DELETE FROM MyTable WHERE Id= X'4ffbd580b17d4731b162ede8d698e026';

I know I'm late for this, but it might just be useful for someone with the same problem.

I have a uniqueidentifier type of column in one of my tables and when I execute a select query without any conditions, it returns the result guid column values in this format -

{000B6A69-04D6-C557-7EA3-08CF8C8AD84B}

(Yes, with the braces)

I found out using typeof() function that my guid column values had been stored as text. So, I just tried out four different statements and luckily, the 4th one worked -

    1. select myGuidColumn, typeof(myGuidColumn) from MyTable WHERE [myGuidColumn] = '000B6A69-04D6-C557-7EA3-08CF8C8AD84B' --didn't work
    2. select myGuidColumn, typeof(myGuidColumn) from MyTable WHERE [myGuidColumn] = '{000B6A69-04D6-C557-7EA3-08CF8C8AD84B}' --didn't work
    3. select myGuidColumn, typeof(myGuidColumn) from MyTable WHERE [myGuidColumn] LIKE '{000B6A69-04D6-C557-7EA3-08CF8C8AD84B}' --didn't work
    4. select myGuidColumn, typeof(myGuidColumn) from MyTable WHERE [myGuidColumn] LIKE '000B6A69-04D6-C557-7EA3-08CF8C8AD84B' --it works!
