MYSQL Truncated incorrect DOUBLE value while updating

问题

Here is request for mysql database.
"UPDATE client_storrage SET LastMatched=UTC_TIMESTAMP() WHERE XUID=01100000000000"
It gives error Truncated incorrect DOUBLE value: '01100000000000'
XUID varchar(20) utf8_bin
LastMatched datetime
Can any one help to fix this ?

回答1:

if XUID is a varchar you have to use quotes around it in your query:

UPDATE client_storrage 
SET LastMatched = UTC_TIMESTAMP() 
WHERE XUID = '01100000000000'
