I need to convert base64 string to bytea type. But when I Executed SQL statements by the pgAdminIII：
select decode("ygAAA", 'base64');
I got the following error message:
ERROR: syntax error at or near ")"
LINE 1: select decode('ygAAA', 'base64');
^
********** 错误 **********
ERROR: syntax error at or near ")"
SQL 状态: 42601
字符:59
My postgresql's version is 8.2.15. And I could use encode function.
I googled it, but didn't find the solution. Can somebody help me? TKS!
Try it with single quotes instead of double quotes. Also base 64 strings turn groups of 4 characters into 3 bytes (24 bits in 3 bytes are spread across the lower 6 bits of 4 characters.) So your base64 string is invalid.
This works:
select decode('ygAA', 'base64');
Hope this helps,
Adam.

I want to use to_char function in Postgresql but take an error when execute the script.
Oracle version is ok;
to_char('7374961057827412212','XXXXXXXXXXXXXXXXXXXX')
result : 66592002042458F4
But I could not find Postgresql version and take an error like this;
ERROR: function to_char(text, unknown) does not exist
If you look at the table of formatting codes for numbers, you will see that X is not supported, and indeed there is no way to get hexadecimal output with to_char.
But you can use to_hex:
SELECT to_hex(7374961057827412212);
to_hex
══════════════════
66592002042458f4
(1 row)
The error message you see is because you entered the first argument in single quotes, so it is a string (data type text), but there is no to_char function to format strings as strings (they are already strings).
I'm playing hackthebox machine's and current one has a postgresql db in place. The query breaks with ' and appeas as follows:
ERROR: unterminated quoted string at or near "'" LINE 1: Select * from
cars where name ilike '%test'%' ^
I understand that % is being used to search within the query string for the characters provided but, What is ^ used for?
Bold highlights my test query
All my searches yielded resulst regarding regexes and caret signaling the start of the string. Plus other result about using cli or something like that.
Can anybody tell me what is it doing at the end of the query?
Your are looking for the use of the caret specifically within error messages.
If I run this query:
psql -c " Select * from cars where name ilike '%test'%'"
This is what I get, preserving line breaks and spaces:
ERROR: unterminated quoted string at or near "'"
LINE 1: Select * from cars where name ilike '%test'%'
^
The caret points to where on the previous line the error occurred. In this case, that is where the opening quote mark that never got closed was located.
If you are using a tool which malformats your error messages, you should consider changing to one that does not or otherwise figuring out how to fix it.
I installed Mimic3 database in Pg11, and try to query using the code from here: https://mimic.physionet.org/tutorials/intro-to-mimic-iii-bq/ solution to step 1.
SELECT ie.subject_id, ie.hadm_id, ie.icustay_id,
ie.intime, ie.outtime
FROM `physionet-data.mimiciii_clinical.icustays` ie;
but I got the error.
ERROR: syntax error at or near "`"
LINE 3: FROM `physionet-data.mimiciii_clinical.icustays` ie
^
, Time: 0.004000s
And if I deleted those two backticks, I got the warning.
ERROR: syntax error at or near "-"
LINE 3: FROM physionet-data.mimiciii_clinical.icustays ie
^
, Time: 0.002000s
And if I explaced ` with ", it showed the error that:
ERROR: relation "physionet-data.mimiciii_clinical.icustays" does not exist
LINE 3: FROM "physionet-data.mimiciii_clinical.icustays" ie
^
, Time: 0.002000s
Hope somebody can tell me what was wrong. Thank you!
Postgres doesn't use backticks to quote table names, it uses double quotes, and dots aren't allowed in names without quoting, so you probably want this:
SELECT ie.subject_id, ie.hadm_id, ie.icustay_id,
ie.intime, ie.outtime
FROM "physionet-data.mimiciii_clinical.icustays" ie;
When I execute a SQL command via libpq, it reports error message if there's some error something like this.
Error Domain=PQConnection Code=1 "ERROR: syntax error at or near "fef"
LINE 1: fef
^
This is string message. I can parse the message - because it's very regular - to get line/column number, but that's unreliable. Is there any other API to get line/column numbers? Any regularized integer form would be nice.
Use PQresultErrorField function with key PG_DIAG_STATEMENT_POSITION.
From manual
PG_DIAG_STATEMENT_POSITION A string containing a decimal integer
indicating an error cursor position as an index into the original
statement string. The first character has index 1, and positions are
measured in characters not bytes.

Postgres error on insert - ERROR: invalid byte sequence for encoding "UTF8": 0x00
(7 answers)
Closed 9 years ago.
I'm trying to import a tab separated values file into a PostgreSQL database using the "COPY" command. The problem is that is fails on a line with the error message
ERROR: invalid byte sequence for encoding "UTF8": 0x00
The bad line can be found in this file.
It still fails when I try to import this single-line file.
I tried to open the file but it looks like a normal text file and I cannot find anyway to resolve this problem. The schema of the table looks like
CREATE TABLE osm_nodes (
id BIGINT,
longitude double precision,
latitude double precision,
tags TEXT
);
I use the following command to copy the file
cat bad_lines2 | psql -c "COPY osm_nodes FROM STDIN WITH DELIMITER ' '"
(Note: The delimeter above is the tab character)
I use (PostgreSQL) 9.2.3.
Thanks for your help.
I found the error. The text contains "\09" which was translated as a tab character and caused this problem. Each "\" should be escaped by "\" so that it can be inserted correctly.
