I've been trying to update a field in MySQL database but I'm getting an error.
This is my Query
UPDATE tbl SET fl1="val",fl2="val", fl3="val" WHERE fl0="val val"
This is the error I received when I tried to execute the query
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'val WHEREfl0="val val"' at line 1
I have removed the information from the query and replaced it with dummy text.
Taking a look at the error, I see 2 issues
val WHEREfl0="val val"
first of all, WHEREfl0 should probably be WHERE fl0
Secondly an issue here val WHERE[..] I think you are missing " there.
val" WHERE fl0="val val"
I am guessing you fixed the query while adding dummy text because this query is correct:
UPDATE tbl SET fl1="val",fl2="val", fl3="val" WHERE fl0="val val"
FOUND IT :D ... I'm having multiple queries to be executed, this is done using PHP ... The problem was in a query in the middle was like this:
UPDATE tbl SET fl1='val',fl2='val', fl3=''val WHERE fl0='val val'
THANK YOU ALL FOR YOUR SUPPORT.
Try using single quotes, not double. ('')
UPDATE tbl SET fl1='val',fl2=val', fl3='val' WHERE fl0='val val'
You should also use the "`" in your syntax:
UPDATE `tbl` SET `fl1`='val',`fl2`=val', `fl3`='val' WHERE `fl0`='val val'
how about this?
UPDATE `tbl`
SET `fl1` = 'val',
`fl2` = 'val',
`fl3` = 'val'
WHERE `fl0` = 'val val'
1.) I have changed Double Quote into Apostrophe.
2.) I added backtick in case one of your columns contains a reserved word.

I am trying to run a select statement of a string column to set out alphanumeric values free of pure integars using the following statement:
select some_col_1 from some_table where some_col_1 = 'some value' and length(cast(some_col_1 as unsigned)) != length(some_col_1)
Whereas, I am trying to update some other column based on that condition using update statement,
My problem is, whenever I attempt to run the select statement, it is being successfully executed, meanwhile when I essentially use an update statement only gives some kind of unexpected error which is: ERROR 1292 (22007): Truncated incorrect INTEGER value: 'the first non-integer result from my table'.
I just can't figure out why it is doing this. Is there any experts who can see anything odd in my update statement? I am using mysql server version 8.0 and my update stmt precisely goes as follows:
update some_table set some_col_2 = true where some_col_1 = 'some value' and length(cast(some_col_1 as unsigned)) != length(some_col_1)
Your support with this would be very highly appreciated,
Thank you in advance,
What you are running into is mysql's sloppy way of implementing STRICT_TRANS_TABLES mode, which is intended to give an error when trying to set a value to something that has to be modified to meet the column's specification.
mysql chose to implement this by making things like cast or date parsing just give errors, instead of warnings, when done in a data modification statement, even when those expressions weren't what was actually attempted to be stored.
You can either disable STRICT_TRANS_TABLES mode for the duration of your update:
set session sql_mode=replace(##sql_mode,'STRICT_TRANS_TABLES','');
update ...
or use an alternate way of detecting your case that doesn't involve something that triggers a warning, or under STRICT_TRANS_TABLES, an error. For instance:
update some_table set some_col_2=true where some_col_1 not regexp '^([1-9][0-9]*|0)$';
I am trying to find a weird character thats in front of my £ sign and replace it with nothing.
Coding I tried was
update [orders_total]
set [text]=replace([text],'[Â]','[]');
but mysql returns this
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use
near '[orders_total] set [text]=replace([text],'[Â]','[]')' at line 1
I know nothing of Mysql but its going to take me ages to manually remove these chars so any help would be much appreciated.
Thanks in advance
Thats not mysql syntax and in mysql it should be as
update orders_total
set text=replace(text,'Â','');
Abhik is absolutely right in his answer. An alternate form of writing MySQL queries is:
update `orders_total` set `text` = replace(`text`, '..', '...');
Backticks are not required. They may be valuable when a table's column is named order, for example. Order is a reserved keyword used in order by ... clause. In order to use a reserved keyword like order, use backticks.
Example:
select `order`, `id`, ... from `tablename` where .... order by `order`;
IF OBJECT_ID(N`db_291702_2`.`aaCoRrankingDateManage`, N'U') IS NOT NULL
BEGIN
PRINT 'Table Exists'
END
What is wrong with this? Why do I get errors?
Neither of the suggested ways in how-to-check-if-a-table-exists-in-sql-server/ works for me.
PS. "does not work" means errors like
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''db_291702_2'.'aaCoRrankingDateManage' LIMIT 0, 30' at line 1
Additional info:
I am using phpMyAdmin, my two databases are called db_291702_1 and db_291702_2, the latter has two tables, one of them is called aaCoRrankingDateManage
If you want to escape table or column names then use backticks
select `group` from table1
A static string must be included in quotes
select * from users where name = 'john'
And the syntax of every DB engine is a little bit different. The above works for MySQL, but SQL-Server has a different syntax. There you use brackets [] to escape names.
But you only need to escape names if you use reserved words. You don't have to escape everything.
The given source code is no MySQL Code.
I want to extract a text field from a database and insert it into some other database. So while extracting I used the REPLACE(message_text,'\'', '"') while selecting the test. I gave me an error. I changed that from my select statement and did it while initiating the global variable.
etl.globals['message_text'] = message_text;
still I'm getting an error at the insert statement
insert into lcs_al_user_likes(user_id,liked_user_id,post_content,loop_id) values('${etl.globals['posted_by']}','${etl.globals['liked_user_id']}','${etl.globals['message_text']}',?batchLoopCounter);
saying
*You have an error in your SQL syntaxcheck the manual that corresponds to your MySQL server version for the right syntax to use near 'message_text']}')' at line 1*
I think it is not getting the global variable. That I say because when i print its value using log it just gives me
${etl.globals['message_text']}
as output. So please help me out here.
<query connection-id="lcsDBConnection">
SELECT forum_topic_post_id AS forum_topic_post_id, posted_by AS posted_by,message_text as message_text FROM lcs_tbl_forum_topic_post WHERE like_count>0 LIMIT ?batchSize OFFSET ?queryCounter ;
<script connection-id="jexl">
etl.globals['forum_topic_post_id'] = forum_topic_post_id;
etl.globals['posted_by'] = posted_by;
etl.globals['message_text'] = message_text.replace('\'', '"');
</script>
It looks like the problem is in INSERT statement, you should use prepared statement
parameters escaping:
INSERT INTO lcs_al_user_likes(user_id,liked_user_id,post_content,loop_id) values(?{etl.globals['posted_by']},?{etl.globals['liked_user_id']},?{etl.globals['message_text']},?batchLoopCounter);
BTW As I understand, your original problem was quotes breaking the insert statement, so in this case with ?{parameter} syntax you don't need to use replace(...) function at all.
I have this query
update user_remember_me set
when='2012-07-06 05:44:27',
hash='c8e9d2c0dd156b5c68d0b048e5daa948e6b8fac7'
where user = '21';
and I am getting this error
Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'when='2012-07-06 05:44:27', hash='c8e9d2c0dd156b5c68d0b048e5daa948e6b8fac7' wher' at line 1
Im failing to miss the connection here, I've used simple updates like this everywhere without issue til this, maybe Im getting to tired, but this is gonna drive me nuts til I have an answer
When is a key word in mysql, change the column name
or you can use it as
`when`='2012-07-06 05:44:27'
when is a reserved word in mysql
update user_remember_me set
`when`='2012-07-06 05:44:27',
`hash`='c8e9d2c0dd156b5c68d0b048e5daa948e6b8fac7'
where user = '21';
So you must backtick your column
when is a keyword within MySQL. You have to escape it, if you want to use it as a column identifier (as you should with all column identifiers!):
UPDATE user_remember_me
SET
`when`='2012-07-06 05:44:27',
`hash`='c8e9d2c0dd156b5c68d0b048e5daa948e6b8fac7'
WHERE `user` = '21';
