I am trying to delete an attribute which is binary from an entity using following
mod_list = [(ldap.MOD_DELETE, 'attr_name', 'attr_value')]
ldap_con.modify_s('cn=entity_name,ou=entity_ou,dc=entity_dc', mod_list)
But this is leading to the issue
INAPPROPRIATE_MATCHING: {'info': 'modify/delete: attr_name: no equality matching rule', 'desc': 'Inappropriate matching'}
Binary attribute type does not allow any equality matching rule, so I did not put and EQUALITY rule in this attribute definition in schema then what is wrong I am doing here.
Please let me know if there is any other way of deleting binary attribute from an entity in openldap
At last came to know that it is not possible to delete binary data but we can replace it with empty string.
This is because no 'equality' match available for binary data

I am new to cpp. I have some Parquet with part of its schema like this:
optional binary one (UTF8);
optional group two (LIST) {
repeated group list {
optional binary element (UTF8);
}
}
optional binary three (UTF8);
I'm using Arrow's parquet::StreamReader to read it like in this example.
It's clear to me how to read fields one and three, and one works fine, but not two, so I can't reach three. For two, I'm not sure what cpp type to use. I know the logical type is "list" and below is the output from assigning it into std::string just to get the inferred type from the error, but it shows me 'UNKNOWN':
libc++abi.dylib: terminating with uncaught exception of type parquet::ParquetException:
Column physical type mismatch. Column 'two' has physical type 'UNKNOWN' not 'BYTE_ARRAY'
I would just skip this column entirely (I don't require it) but am unclear how I can do that without parsing it.
It turns out it is not possible to use StreamReader except on primitive types. However, I was able to use StreamReader::SkipColumns to skip two and then parse three.
I am working in an environment without a JSON parser, so I am using regular expressions to parse some JSON. The value I'm looking to isolate may be either a string or an integer.
For instance
Entry1
{"Product_ID":455233, "Product_Name":"Entry One"}
Entry2
{"Product_ID":"455233-5", "Product_Name":"Entry One"}
I have been attempting to create a single regex pattern to extract the Product_ID whether it is a string or an integer.
I can successfully extract both results with separate patterns using look around with either (?<=Product_ID":")(.*?)(?=") or (?<=Product_ID":)(.*?)(?=,)
however since I don't know which one I will need ahead of time I would like a one size fits all.
I have tried to use [^"] in the pattern however I just cant seem to piece it together
I expect to receive 455233-5 and 455233 but currently I receive "455233-5"
(?<="Product_ID"\s*:\s*"?)[^"]+(?="?\s*,)
, try it here.
I'm extracting information from logs in hive with this sentences:
regexp_extract(values, "^(\\w{3} \\s?\\d+ \\d\\d:\\d\\d:\\d\\d \\w+-\\w+ \\w+:) (\\[)(\\d{2})(\\/)(\\w{3})(\\/)(\\d{4})(.*\\])",3)day,
regexp_extract(values, "^(\\w{3} \\s?\\d+ \\d\\d:\\d\\d:\\d\\d \\w+-\\w+ \\w+:) (\\[)(\\d{2})(\\/)(\\w{3})(\\/)(\\d{4})(.*\\])",5)month
I use the same regular expression for extract two fields in two different regex_extract call. It is possible to extract more than one field only executing regex_extract once?
Maybe not exactly what you are looking for, but if your really want to have one extraction that will give you multiple fields instead of one, this is what I found:

Note that for this solution you need to write a UDF with object inspectors, but see for yourself.
I have encountered problem in yaml-cpp parser. When I try to load following definition:
DsUniversity:
university_typ: {type: enum, values:[Fachhochschule, Universitat, Berufsakademie]}
students_at_university: {type: string(50)}
I'm getting following error:
Error: yaml-cpp: error at line 2, column 39: end of map flow not found
I tried to verify yaml validity on http://yaml-online-parser.appspot.com/ and http://yamllint.com/ and both services reports yaml as valid.
Problem is caused by missing space after "values:" definition. When yaml is updated to following format:
DsUniversity:
university_typ: {type: enum, values: [Fachhochschule, Universitat, Berufsakademie]}
students_at_university: {type: string(50)}
everything works as expected.
Is there any way how to configure/update/fix yaml-cpp parser to proceed also yamls with missing space after colon?
Added:
It seems that problem is caused by requirement for empty char as separator. When I simplified testing snippet to
DsUniversity:[Fachhochschule, Universitat, Berufsakademie]
yaml-cpp parser reads it as one scalar value "DsUniversity:[Fachhochschule, Universitat, Berufsakademie]". When empty char is added after colon, yaml-cpp correctly loads element with sequence.
yaml-cpp is correct here, and those online validators are incorrect. From the YAML 1.2 spec:
7.4.2. Flow Mappings
Normally, YAML insists the “:” mapping value indicator be separated from the value by white space. A benefit of this restriction is that the “:” character can be used inside plain scalars, as long as it is not followed by white space. This allows for unquoted URLs and timestamps. It is also a potential source for confusion as “a:1” is a plain scalar and not a key: value pair.
...
To ensure JSON compatibility, if a key inside a flow mapping is JSON-like, YAML allows the following value to be specified adjacent to the “:”. This causes no ambiguity, as all JSON-like keys are surrounded by indicators. However, as this greatly reduces readability, YAML processors should separate the value from the “:” on output, even in this case.
In your example, you're in a flow mapping (meaning a map surrounded by {}), but your key is not JSON-like: you just have a plain scalar (values is unquoted). To be JSON-like, the key needs to be either single- or double-quoted, or it can be a nested flow sequence or map itself.
In your simplified example,
DsUniversity:[Fachhochschule, Universitat, Berufsakademie]
both yaml-cpp and the online validators parse this correctly as a single scalar - in order to be a map, as you intend, you're required a space after the :.
Why does YAML require that space?
In the simple plain scalar case:
a:b
could be ambiguous: it could be read as either a scalar a:b, or a map {a: b}. YAML chooses to read this as a scalar so that URLs can be easily embedded in YAML without quoting:
http://stackoverflow.com
is a scalar (like you'd expect), not a map {http: //stackoverflow.com}!
In a flow context, there's one case where this isn't ambiguous: when the key is quoted, e.g.:
{"a":b}
This is called JSON-like because it's similar to JSON, which requires quotes around all scalars. In this case, YAML knows that the key ends at the end-quote, and so it can be sure that the value starts immediately.
This behavior is explicitly allowed because JSON itself allows things like
{"a":"b"}
Since YAML 1.2 is a strict superset of JSON, this must be legal in YAML.
I think it would be beneficial to parse scalar/keys differently immediately inside a flow map{, if you agree, vote here please.

I have a bunch of sql statements updated by my team developers.
I intend to run a check before these statements are run against a db.
for example, check if a certain column is hardcoded instead of being fetched from the respective table (foreign key)
for example:
INSERT INTO [Term1] ([CreatedBy]
,[CreateUser]) values(1,'asdadad')
where 1 is hardcoded value.
Is there a regular expression that can extract all insert statements from the file so that they can be parse?
I tried with this expression http://regexlib.com/REDetails.aspx?regexp_id=1750 but it didnot work
You may need to run a multi-level regex on this. First parse the entire parameter string from the whole query, then parse each individual field from the paramter string that you previously got to get each one specifically ignoring all the other characters that may come up.
