Why this query is not working:
UPDATE country SET timezones="[{"zoneName":'Asia\/Kabul',"gmtOffset":16200,"gmtOffsetName":'UTC+04:30',"abbreviation":'AFT',"tzName":'Afghanistan Time'}] " where name='Afghanistan'
Error I get:
ERROR: syntax error at or near "zoneName"
LINE 1: UPDATE country SET timezones="[{"zoneName":'Asia/Kabul',"gm...
^
SQL state: 42601
Character: 34
the issue with your SQL statement is that the literal string you are trying to set timezones to contains improperly formatted escape characters. if you wanted to avoid that first error you can double up on quotes like timezones="[{""zoneName"": ...
you can go to the link to see more about string formating in SQL. good luck!
You're trying to update the value wrapping the string in quotes. You need to wrap the string in single quotes timezones='[{"zoneName":'Asia...}]'
However, to TitledTeapot's point, you will also have to escape the existing single quotes in your string, so you'd end up with something like this:
'[{"zoneName":''Asia\/Kabul'',"gmtOffset":16200,"gmtOffsetName":''UTC+04:30'',"abbreviation":''AFT'',"tzName":''Afghanistan Time''}]'

I am getting a syntax error in a PostgreSQL query. I am working on a project developed in YII1, I am getting an error
CDbCommand failed to execute the SQL statement: SQLSTATE[42601]:
Syntax error: 7 ERROR: syntax error at or near "s" LINE 1: ...OT NULL
AND sub_heading like '%Women and Children's Voices%'.
As you can see above, I am using the like operator in single quotes, and in the string there is another single quote (Children's). So PostgreSQL is throwing me an error. Please provide me a solution to escape the string.
You can escape a single quote in a string by using another single quote (i.e., '' instead of '. Note that these are two ' characters, not a single " character):
sub_heading LIKE '%Women and Children''s Voices%'
-- Here -----------------------------^
You should use the format function to construct the SQL statement, using the %L placeholder for the pattern.
I solved this problem by replacing the single quote with double quotes using PHP. Here is the code
There is a variable $var with value Women and Children's Voices. I replace that single quote using the str_replace() function.
$var = str_replace("'", "''", $var);
I am trying to run a SQL query which is quite straightforward. The query is:
UPDATE dbo.Machine
SET dbo.Machine.ServerName="Server"
WHERE dbo.Machine.ServerName IS NULL;
I am getting the following error on Server
Invalid column name 'Server'.
Am I missing something ?
String should be declared with single quotes ' '
SET dbo.Machine.ServerName= 'Server'
Double quotes is for fieldnames
I'm trying to use REGEXP_REPLACE to remove all punctuation from a varchar. I'm using the following:
regexp_replace(d.NAME, [.,\/#!$%\^&\*;:{}=\-_`~()])
But it gives me an error, saying:
Statement 1 is not valid. ERROR: syntax error at or near "."
How can I fix this to remove all punctuation?
Firstly, the dash in a character class means a range, except when it's first or last... so put it there:
[.,\/#!$%\^&\*;:{}=\_`~()-]
And, you have to put it in quotes, and most characters don't need escaping:
regexp_replace(d.NAME, '[.,/#!$%^&*;:{}=_`~()-]')
In Django, the following statement
entity_name = "a string with a ' quote"
Fiche.objects.extra(where=["'%s' LIKE fiche_name+'%s' " % (entity_name,'%%')])
causes the Database error:
DatabaseError: ('42000', '[42000] [FreeTDS][SQL Server]Statement(s) could not be prepared. (8180) (SQLExecDirectW)')
If I print the sql that is sent to db backend, I see something like this:
... 'a string with a ' quote' LIKE fiche_name+'%%'
so I tried to escape the quote in my string with a backslash
entity_name = "a string with a \\\' quote"
This time, the query seems to be well prepared for the DB backend (quote escaped):
... 'a string with a \' quote' LIKE fiche_name+'%%'
but this results in the same database error.
Does someone know how to escape properly the quote?
EDIT: I found a solution to my problem: I replace in my string each quote by two quotes and it works now:
entity_name = entity_name.replace("'","''")
Way too late, but the right way to do this is to pass the variables as arguments to .extra():
entity_name = "a string with a ' quote"
Fiche.objects.extra(where=["%s LIKE fiche_name + '%%'")], params=[entity_name])
Note: what you are doing is the opposite of what is normally done (field LIKE 'pattern%'), but it's possible nonetheless. Also note that this is database-specific code, not all databases use + as string concatenator (you may have to switch it to || or CONCAT()).
I have a string that is read from an excel file. String is ¬©K!n?8)©}gH"$.F!r'&(®
I keep getting the following error. When running the insert statement
ERROR [42601] [IBM][CLI Driver][DB2/NT] SQL0007N The character "\" following " K!n?8) }gH""$.F!r'" is not valid. SQLSTATE=42601
How do I do this insert with the \ character in the string? The Character causing the problem might also be the &.
Its a DB2 Database
Thanks
It depends on which interface you are sending the insert statement.
In my experience, it is most probably the typewriter single quote character (') which makes the problem.
INSERT INTO TEMP.CHAR_TEST
VALUES ('¬©K!n?8)©}gH"$.F!r''&(®');
works fine for me, but notice that I have changed ' to '' (insert another single quote after the existing one).
