I am trying to make my big migration more self explaining and that's why I need to add some comments to it. However, I tried a few approaches and haven't succeeded with them.
I tried:
//
#
<!-- TEXT -->
Error:
SQL State : 42601
Error Code : 0
Message : ERROR: syntax error at or near "//"
Position: 1
Is there a way I can add a comment to flyway SQL migration?
The following should work on all supported databases:
/* Single line comment */
/*
Multi-line
comment
*/
-- Sql-style comment
And additionally on MySQL and MariaDB:
# MySQL-style single line comment
When we were upgrading to spring-boot 2.5 we found that there is need to have a space after first two hyphens -- with SQL style comments
Use ANSI SQL's -- for comments!

I have noticed that the highlight missing after the ARRAY expression [ ].
The PSQL script can be run successfully but it's quite annoying.
SELECT ARRAY [ CONCAT('0', SUBSTRING(REGEXP_REPLACE(test.elec_num, '[^0-9]', '', 'g') FROM 3)) ]
FROM test
WHERE LENGTH(test.elec_num) > 10;
Is there any way to fix this issue?
I think the issue is that the SQL language support that comes out of the box with Visual Studio Code is configured for T-SQL, instead of PL/pgSQL like Postgres implements. It looks like the single quotes are throwing the syntax highlighting off in your case.
I found a Postgres Extension, called PostgreSQL that after installing, the syntax of your SQL above looks more appropriate (note, this is also after changing the language to postgres, which is added by this extension):
I'm having an issue matching regular expression in BigQuery. I have the following line of code that tries to identify user agents:
when regexp_contains((cs_user_agent), '^AppleCoreMedia\/1\.(.*)iPod') then "iOS App - iPod"
However, BigQuery doesn't seem to like escape sequences for some reason and I get this error that I can't figure out:
Syntax error: Illegal escape sequence: \/ at [4:63]
This code works fine in a regex validator I use, but BigQuery is unhappy with it and I can't figure out why. Thanks in advance for the help
Use regexp_contains((cs_user_agent), r'^AppleCoreMedia\/1\.(.*)iPod')
I want to update a row in a table for my project, I'm copying a syntax I saw somewhere else here however, I think my problem comes when I try updating where ApplicantID is equal to $_SESSION["ID"].
I get this error
Parse error: syntax error, unexpected '"', expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in C:\xampp\...\InsertPData.php on line 22
here is the php along side the SQL:
<?php
include_once'dbconnect.php';
session_start();
function INSERT()
{
$Name=$_POST['name'];
$Relation=$_POST['Relation'];
$Email=$_POST['Email'];
$Address=$_POST['Address'];
$Postcode=$_POST['Postcode'];
$Mobile_Number=$_POST['Mobile_Number'];
$Home_Number=$_POST['Home_Number'];
$INSERT="UPDATE Applicants
SET ParentName='$Name',
Relationtoapplicant='$Relation',
ParentEmail='$Email',
ParentAddress='$Address',
ParentPostcode='$Postcode',
ParentMobile='$Mobile_Number',
ParentHome='$Home_Number',
WHERE ApplicantID=$_SESSION["ID"] "; #THIS IS LINE 22
$data=mysql_query($INSERT) or die(mysql_error());
if($data)
{
echo "Parents/Gauridan details hav been entered";
}
else print "error";
}
INSERT()
?>
I've already searched for a solution to this but haven't found something where the user is using a session thing. Thank you.
This is why an IDE with syntax highlighting is helpful. StackOverflow uses syntax highlighting on code blocks as well and actually already gives you the answer based on your code:
$INSERT="UPDATE Applicants
WHERE ApplicantID=$_SESSION["ID"] ";
See how ID is suddenly black instead of dark red? That's because you are terminating the string there. The double quotes should either be escaped or replaced with single quotes, like:
$INSERT="UPDATE Applicants
WHERE ApplicantID=$_SESSION[\"ID\"] ";
Or
$INSERT="UPDATE Applicants
WHERE ApplicantID=$_SESSION['ID'] ";
See how the ID bit stays dark red? This is because now your string is not suddenly terminated.
Also, please do not use mysql_ functions anymore. They have been deprecated since 2013 and are currently not even a part of PHP anymore. So if you'd update your PHP to the latest version, this code would not work. On top of that, this code is vulnerable to SQL injection attacks.
Also see Why shouldn't I use mysql_* functions in PHP? and How can I prevent SQL-injection in PHP?.
How I can execute sql statements including comments in pgadmin sql editor?
Neither -- nor /* syntax is working, that is gives me this error:
ERROR: syntax error at or near ""
LINE 1: /*
For comments in PGAdmin SQL editor use -- or /*.... */ notation.
If you use something like
""" comment """
select * from database
you get following syntax error
ERROR: syntax error at or near """" comment """".
I'm trying to insert ODI step error message into oracle table.
I captured the error message using <%=odiRef.getPrevStepLog("MESSAGE")%>.
ODI-1226: Step PRC_POA_XML_synchronize fails after 1 attempt(s).
ODI-1232: Procedure PRC_POA_XML_synchronize execution fails.
ODI-1227: Task PRC_POA_XML_synchronize (Procedure) fails on the source XML connection XML_PFIZER_LOAD_POA_DB_DEV.
Caused By: java.sql.SQLException: class java.sql.SQLException
oracle.xml.parser.v2.XMLParseException: End tag does not match start tag 'tns3:ContctID'.
at com.sunopsis.jdbc.driver.xml.SnpsXmlFile.readDocument(SnpsXmlFile.java:459)
at com.sunopsis.jdbc.driver.xml.SnpsXmlFile.readDocument(SnpsXmlFile.java:469)
When I try to insert this into a table, I'm getting the following error:
Missing IN or OUT parameter at index:: 1
I tried with substr, replace. Nothing works as in middle of the error message we have a single quotes 'tns3:ContctID'.
Is there any way to insert this into a table?
that's a tough one if you want to use pure java BeanShell and you've given way too little details to get short and straight answer, like
how do you try to insert this (command on source/target, bean shell only, Oracle SQL +jBS, jython, groovy etc...)
The problem here is not only quotes but also newlines.
To replace them is even more difficult as every parsing step <%, <?, <# requires different trick to define those literals
What will work for sure is if you write Jython task for inserting log data (Jython in technology).
There you may use Python ability for multiline string literals
simply:
⋮
err_log = """
<?=odiRef.getPrevStepLog("MESSAGE")?>
"""
⋮
I faced this error few days back . I applied below mentioned solution in ODI ...
Use - q'#<%=odiRef.getPrevStepLog("MESSAGE")%>#'
This will escape inverted comma (') for INSERT statement.
I have used this in my code and it is working fine :)
For example -
select 'testing'abcd' from dual;
this query will give below error
"ORA-01756: quoted string not properly terminated"
select q'#testing'abcd#' from dual;
This query gives no error and we get below response in SQL Developer
testing'abcd
