I need some help with this Hive Query please.
Table name is frame_curated
Column name is Message
Column type is string
In that column the data is formatted like this:
IP":"1735", "ID":"G54X"
I'm looking for records where ID="G54X" in column Message.
Something like this
Select * FROM frame_curated WHERE frame_curated.Message LIKE '%G54X%'
From my research, I think it should look like this:
Select * FROM frame_curated WHERE frame_curated.Message.ID ['G54X']
But its not working.
Your help is sincerely appreciated.

I don't think frame_curated.Message.ID ['G54X'] would work for string data type. it could only work if your data type is List<dict<string:string>>
you can use something like this
select * from temp.test2 where value like '%"ID":%G54X%'
The other approach is, you change the table datatype to complex and run the query you suggested.

My overall goal is to create new tables by selecting columns in existing tables with certain patterns/tags in their column names. This is in SQL Server.
For example, I have a common need to get all contact information out of a company table, and into its own contact table.
I haven't been able to find a programmatic approach in SQL to express excluding columns from a SELECT statement based on string.
When looking to options like the COL_NAME function, those require an ID arg, which kills that option for me.
Wishing there was something built in that could work like the following:
SELECT *
FROM TABLE
WHERE COL_NAME() LIKE 'FLAG%'
Any ideas? Open to anything! Thanks!!
One trick could be to firstly using the following code to get the column names you desire:
select * from information_schema.columns
where table_name='tbl' and column_name like 'FLAG%'
Then concatenate them into a comma-delimited string and finally create a dynamic sql query using the created string as the column names.
In my PostgreSQL database I have table that is inside import schema. When I want to get all data from the column I do:
select * from import.master_plan
This query works fine. But when I try to for example get only title column values:
select import.master_plan.title from import.master_plan;
it returns:
ERROR: column master_plan.title does not exist
LINE 1: select import.master_plan.title from import.master_plan;
^
HINT: Perhaps you meant to reference the column "master_plan. title".
I've also tried:
select title from import.master_plan;
but this also not works. I'm using PostgreSQL 10. How can I fix that?
I would suggest that you use a table alias instead:
select mp.title
from import.master_plan mp;
This is much easier to read and to type.
Judging from the error message, though, the name seems to have leading spaces. Something like:
select mp." title"
from import.master_plan mp;
might work. If this is the case, alter the table and rename the column.
I have datasets of the same structure and i know I can query them like this, they are named by date:
SELECT column
FROM [xx.ga_sessions_20141019] ,[xx.ga_sessions_20141020],[xx.ga_sessions_20141021]
WHERE column = 'condition';
However I actually want to query various months of this data... so instead of listing them all in the same way as above, is there syntax that you can use that looks like:
SELECT column
FROM [xx.ga_sessions_201410*] ,[xx.ga_sessions_201411*]
WHERE column = 'condition';
Take a look at the table wildcard functions section of the BigQuery query reference. TABLE_DATE_RANGE or TABLE_QUERY will work for you here. Something like:
SELECT column
FROM TABLE_DATE_RANGE(xx.ga_sessions_,
TIMESTAMP('2014-10-19'),
TIMESTAMP('2014-10-21'))
WHERE column = 'condition';
Is there a way to reverse the SQL Like operator so it searches a field backwards? For example, I have a value in a field that looks like this "Xbox 360 Video Game". If I write a query like below, it returns the result fine.
SELECT id FROM table WHERE title like "%Xbox%Game%"
However, when I search like this, it doesn't find any results.
SELECT id FROM table WHERE title like "%Video%Xbox%"
I need it to match in any direction. How can I get around this?
How about:
SELECT id FROM table WHERE title like "%Video%" and title like "%Xbox%"
Another option
SELECT id FROM table WHERE title RLIKE "(Xbox|Video)"
Well given I have a value I want to check for potential matches in a database (in one varchar field) so I write something like:
SELECT * FROM table WHERE column LIKE "%value%"
Which will work if the value is something like "test" and the column has a value of "this is a test" however if it is reversed then I will not get a match I have tried things along the lines of:
SELECT * FROM table WHERE CONCAT("%",column,"%") LIKE "value"
but don't know exactly how to phrase this to Google to get a response I need, please help!
You can reverse a like statement. Just using the same syntax as a regular like query:
select
*
from
table
where
'value' like concat('%', column, '%')
Of course, if you felt wild and crazy, you could also use instr:
select * from table where instr('value', column) > 0
I don't know which one is faster, since I don't have a MySQL instance to test against, but it's worth trying both to see which wins.
SELECT *
FROM table
WHERE 'value' LIKE CONCAT('%', column, '%')
