I'm now getting this error after making a small mod to a working program. The structures have the same type (though the tables are different) but I get this error? I've looked at similar postings but couldn't find an answer to this.

A component name cannot contain a dot in its name, in a Unicode program. Same for any other ABAP symbolic name.
The below code with name .include is not permitted. You were mistaken by DDIC structures, which have different rules.
TYPES: begin of TY_RESB_CDC,
...
UTIME type CDUZEIT,
.include type ZBW_MATERIAL_RESVN_RESB,
end of TY_RESB_CDC.
Instead, you should use the ABAP statement INCLUDE TYPE to include the components of a structure (e.g. ZBW_MATERIAL_RESVN_RESB in your case):
TYPES: begin of TY_RESB_CDC,
...
UTIME type CDUZEIT.
INCLUDE TYPE ZBW_MATERIAL_RESVN_RESB.
TYPES: end of TY_RESB_CDC.

I am attempting to solve the Google ASP Competition 2019 : Insurance Referee Assignment problem. The problem is provided in this link.
There is a hard constraint that if a referee has preference type of 0 then the case will not be assigned to that referee. I have simplified the problem to include a few variables.
case(cid) refers to a case with cid as the case id.
ref(rid) refers to the referee with referee id.
pref(rid, type) takes the preference of referee 'rid' and type which takes value from 0 to 3. The higher the number, the more likely it will take the case.
In ref(10, 3) and ref(9, 2), the higher preference will be given to ref(10).
I have tried the following clingo code:
ref(rid).
case(cid).
pref(rid, type).
assign(cid, rid) :- ref(rid), pref(rid, type), type != 0.
case(4).
ref(3).
ref(5).
pref(3, 0).
pref(5, 1).
#show assign/2.
However, when I run the command, it shows satisfiable but outputs only this
assign(cid, rid)
What am I doing wrong?
In clingo variables start with a capital letter and are "valid" just withhin the rule. So my guess is you want the following code:
assign(Rcid, Rrid) :- case(Rcid), ref(Rrid), pref(Rrid, Rtype), Rtype != 0.
case(4).
ref(3). ref(5).
pref(3, 0). pref(5, 1).
#show assign/2.
output:
Solving...
Answer: 1
assign(4,5)
SATISFIABLE
Please note that only renaming the constants to variable names will result in an error message, you have to add case(Rcid) to the rule body as well. Variable names were freely choosen, you can use any variable name as long as it starts with a capital letter.
I have a custom type with code similar to the following (shortened for brevity):
create domain massFraction as jsonb (
value->'h' > 0 and value->'h' is not null
);
Running this provokes the following error:
ERROR: type modifier is not allowed for type "jsonb"
The documentation makes no mention of json being a disallowed base type for a domain.
https://www.postgresql.org/docs/12/sql-createdomain.html
I also thought that it was perhaps the "not null" part of the constraint, which the documentation mentions is "tricky". Additionally, I've tried similar statements without any json operators. All of these seem to be disallowed.
I am obnoxiously prone to not reading documentation, and worse still about understanding documentation when I do bother to read it... so does it not exist, or am I looking in the wrong places to see if this is permitted? Why is it not permitted?
You're missing a CHECK after jsonb:
create domain massFraction as jsonb check (
value->'h' > 0 and value->'h' is not null
);
This results in another error:
ERROR: 42883: operator does not exist: jsonb > integer
HINT: No operator matches the given name and argument types. You might need to add explicit type casts.
I believe what you want is
CREATE DOMAIN massFraction AS jsonb CHECK (
CASE jsonb_typeof(value->'h')
-- only cast when it is safe to do so
-- note: this will reject numeric values stored as text in the json object (eg '{"h": "1"}')
WHEN 'number' THEN (value->>'h')::integer > 0
ELSE false
END
)
The error you're getting comes from the fact that you input is parsed as
CREATE DOMAIN massFraction AS jsonb(<modifier>) -- like in varchar(10)
As an aside I would recommend against using camelCase in postgresql, as massFraction is the same as massfraction (unless quoted) and postgresql will use the lowercased form when reporting errors, hints, etc.
I'm trying to work out how to expand a JSONB field with a jsonb_to_recordset and a custom type.
Postgres 11.4.
This is just a test case, but for the minute I'm trying to work out the syntax. I've got a table named data_file_info with a JSONB field named table_stats. The JSONB field always includes a JSON array with the same structure:
[
{"table_name":"Activity","record_count":0,"table_number":214},
{"table_name":"Assembly","record_count":1,"table_number":15},
{"table_name":"AssemblyProds","record_count":0,"table_number":154}
]
The following code works correctly:
from data_file_info,
jsonb_to_recordset(table_stats) as table_stats_splat (
table_name text,
record_count integer,
table_number integer
)
What I would like to do is pass in a custm type definition instead of the long-form column definition list shown above. Here's the matching type:
create type data.table_stats_type as (
table_name text,
record_count integer,
table_number integer)
Some examples I've seen, and the docs say, that you can supply a type name using a null:row_type casting in the first parameter to jsonb_to_recordset. The examples that I've found use in-line JSON, while I'm trying to pull stored JSON. I've made a few attempts, all have failed. Below are two of the trials, with errors. Can someone point me towards the correct syntax?
FAIL:
select table_stats_splat.*
from data_file_info,
jsonb_populate_recordset(null::table_stats_type, data_file_info) as table_stats_splat;
-- ERROR: function jsonb_populate_recordset(table_stats_type, data_file_info) does not exist

FAIL:

from jsonb_populate_recordset(NULL::table_stats_type, (select table_stats from data_file_info)) as table_stats_splat;
-- ERROR: more than one row returned by a subquery used as an expression. (Line 2)
I'm doubtlessly missing something pretty obvious, and am hoping someone can suggest what that is.
Use the column as the second parameter:
select table_stats_splat.*
from data_file_info,
jsonb_populate_recordset(null::table_stats_type, table_stats) as table_stats_splat;
I load a file which has some columns with data.The first line contains ,CITY,YEAR2000 .
The first column has name of cities.The other columns contain number data.
I am trying to search for a specific city using:
data(data.CITY=='Athens',3:end)
where
data = dataset('File','cities.txt','Delimiter',',')
but I receive an error
Undefined function 'eq' for input arguments of type 'cell'.
--------UPDATE-----------------------------
Ok, use :
data(find(strncmp(data.CITY,'Athens',length('Athens'))),3:end)
Have you tried with using strncmp tangled with find?
I would use it this way
find(strncmp(data.CITY,'ATHENS',length('ATHENS')))
EDIT
Other opportunities to exploit would encompass strfind
strfind(data.CITY,'ATHENS')
EDIT 2
You could also try with
data(ismember(data.CITY,'ATHENS'),3:end)
This should lead you to the results you expect (at least I guess so).
EDIT 3
Given your last request I would go for this solution:
inp = input('Name of the CITY: ','s')
Name of the City: ATHENS
data(find(strncmp(data.CITY,inp,length(inp))),3:end)
I'm using full text search supported by postgres, I installed acts_as_tsearch plugin and it works successfully, but when I tried it later I found an error
runtimeError: ERROR C42883 Mfunction ts_rank_cd(text, tsquery) does
not exist HNo function matches the given name and argument types. You
might need to add explicit type
You need to cast your first parameter into a tsvector.
So let's assume you're searching against a column named foo.text. You will want to change from this:
SELECT ts_rank_cd(foo.text, plainto_tsquery('my search terms')) FROM foo;
to this:
SELECT ts_rank_cd(to_tsvector(foo.text), plainto_tsquery('my search terms')) FROM foo;
or something similar.
If you're using the ## operator elsewhere, you can generally re-use the expressions that operator is operating on.
You can find more documentation on to_tsvector at http://www.postgresql.org/docs/current/static/textsearch-controls.html#TEXTSEARCH-PARSING-DOCUMENTS
EDIT
ts_rank_cd(text, tsquery) does not
exist
This means there is no function with this name that accepts text and a tsquery parameter as input. And that's correct, PostgreSQL doens't have a function using these parameters.
From the manual:
ts_rank_cd([ weights float4[], ]
vector tsvector, query tsquery [,
normalization integer ])
Change your input for the function ts_rank_cd() and you will be fine.
