In SSMS I query for a record by ID, then copy/paste a specific value from the results grid into a new query to search for that specific value and no records are found.
The field is nvarchar & the value in question has an alpha sign, but I don't see why that should cause a problem.
Use:
where ChemicalFormHtml = N'...'

I am trying to create a custom template fragment that builds a table of value properties. I started by creating a SQL query fragment that pulls all properties classified by a Value Type. Now I would like to pull in the default (initial) value assigned. I figured out that it's in the Description table of t_xref, with the property guid in the client field, but I don't know how to write a query that will reliably parse the default value out since the string length may be different depending on other values set. I tried using the template content selector first but I couldn't figure out how to filter to only value properties. I'm still using the default .qeax file but will be migrating to a windows based DBMS soon. Appreciate any help!
Tried using the content selector. Successfully built a query to get value properties but got stuck trying to join and query t_xref for default value.
Edited to add current query and image
Value Properties are block properties that are typed to Value Types. I'm using SysML.
This is my current query, I am no SQL expert! I don't pull anything from t_xref yet but am pulling out only the value properties with this query:
SELECT property.ea_guid AS CLASSGUID, property.Object_Type AS CLASSTYPE, property.Name, property.Note as [Notes], classifier.Name AS TYPE
FROM t_object property
LEFT JOIN t_object classifier ON property.PDATA1 = classifier.ea_guid
LEFT JOIN t_object block on property.ParentID = block.Object_ID
WHERE block.Object_ID = #OBJECTID# AND property.Object_Type = 'Part' AND classifier.Object_Type = 'DataType'
ORDER BY property.Name
I guess that Geert will come up with a more elaborate answer, but (assuming you are after the Run State) here are some details. The value for these Run States is stored in t_object.runstate as one of the crude Sparxian formats. You find something like
#VAR;Variable=v1;Value=4711;Op==;#ENDVAR;
where v1 is the name and 4711 the default in this example. How you can marry that with your template? Not the faintest idea :-/
I can't give a full answer to the original question as I can't reproduce your data, but I can provide an answer for the generic problem of "how to extract data through SQL from the name-value pair in t_xref".
Note, this is heavily dependent on the database used. The example below extracts fully qualified stereotype names from t_xref in SQL Server for custom profiles.
select
substring(
t_xref.Description, charindex('FQName=',t_xref.Description)+7,
charindex(';ENDSTEREO',t_xref.Description,charindex('FQName=',t_xref.Description))
-charindex('FQName=',t_xref.Description)-7
),
Description from t_xref where t_xref.Description like '%FQName%'
This works using:
substring(string, start, length)
The string is the xref description column, and the start and length are set using:
charindex(substring, string, [start position])
This finds the start and end tags within the xref description field, for the data you're trying to parse.
For your data, I imagine something like the below is the equivalent (I haven't tested this). It's then a case of combining it with the query you've already got.
select
substring(
t_xref.Description, #the string to search in
charindex('#VALU=',t_xref.Description,charindex('#NAME=default',t_xref.Description)+6, #the start position, find the position of the first #VALU= tag after name=default
charindex('#ENDVALU;',t_xref.Description,charindex('#VALU=',t_xref.Description))
-charindex('#VALU=',t_xref.Description,charindex('#NAME=default',t_xref.Description))-6 #the length, find the position of the first #ENDVALU tag after the start, and subtract it from the start position
),
Description from t_xref where t_xref.Description like '%#NAME=default%' #filter anything which doesn't contain this tag to avoid "out of range" index errors
I have been searching endlessly for the answer to this problem I have been having:
Our team uses a query that returns a dataset with 13 columns. We want to narrow down the results by returning only rows where any string value in column "Actual Collection" is in the adjacent column "PrvPrComments". Additionally we want to do the same thing for column "Actual Manufacturer" and "PrvPrComments". If a string value in either Actual collection or Actual manufacturer exsists in PrvPrComments then we want to return that row and if it does not then exclude it.
The tricky part is that PrvPrComments is a column that has long text strings in them and so the query needs to parse through to find and match the string. They also need to be exact matches so "Pillow Perfect" and "pillow" would not be the same thing.
Here is an example posted below. I would want to return rows that contains "cowboy" and "chandelier" because there is a match but not the others:
Example of data
My initial guess would be to write a query that uses Full Text Index and/or contains. Any help would be greatly appreciated and I apologize for not having a foundation code to post here, I'm fairly new to this and am having trouble with where to start.
Thank you
where '%' + actualCollection + '%' like PrvPrComments
If data is not that much you can use (like expression) to return the data,
WHERE PrvPrComments LIKE '%' + actualCollection + '%'
But if data is huge and full-text search will not be that much useful, you might have another column as a flag and populate the same at INSERTION time, (when the actualCollection is LIKE PrvPrComments then set the flag as 1 ). later you need to query against rows having flag as 1
I have an issues running around my mind regarding default for 'id' field in my postgresql database. Here is the syntax:-
nextval('unsub_keyword_id_seq'::regclass)
However I'm not really understands even after read the documentations & I would like to set the value only for integer(digit only). I try to alter the column by change regclass to other OIDs but each time it will return errors.
Really appreciate if can get this solved very soon.
Update:
It just come to my idea on the data type for the column after I try & error with the code that will produce the id for the column.
Is integer(postgresql in this case) have it's own default length or not?
If I need to to insert long id, should I set the column length?
Kindly advise.
sorry if my questions quite confusing. your comments may help me to improve it.
From the comments:
I need to insert an id with length of 50 with consist of 2 alphabets & the rest is numeric. the problems occur as the data type is in integer & the data inserting in unsuccessful. is it possible to insert my desired data by retain the data type to integer?
If I understand this correctly, you probably need to format a string, e.g.
format('%s%s', 'XX', nextval('some_sequence_name'))
I have a CLOB(2000000) field in a db2 (v10) database, and I would like to run a simple UPDATE query on it to replace each occurances of "foo" to "baaz".
Since the contents of the field is more then 32k, I get the following error:
"{some char data from field}" is too long.. SQLCODE=-433, SQLSTATE=22001
How can I replace the values?
UPDATE:
The query was the following (changed UPDATE into SELECT for easier testing):
SELECT REPLACE(my_clob_column, 'foo', 'baaz') FROM my_table WHERE id = 10726
UPDATE 2
As mustaccio pointed out, REPLACE does not work on CLOB fields (or at least not without doing a cast to VARCHAR on the data entered - which in my case is not possible since the size of the data is more than 32k) - the question is about finding an alternative way to acchive the REPLACE functionallity for CLOB fields.
Thanks,
krisy
Finally, since I have found no way to this by an SQL query, I ended up exporting the table, editing its lob content in Notepad++, and importing the table back again.
Not sure if this applies to your case: There are 2 different REPLACE functions offered by DB2, SYSIBM.REPLACE and SYSFUN.REPLACE. The version of REPLACE in SYSFUN accepts CLOBs and supports values up to 1 MByte. In case your values are longer than you would need to write your own (SQL-based?) function.
BTW: You can check function resolution by executing "values(current path)"
I'm new to PostgreSQL and I am working on a function to return the word locations for a searched word.
I want to first narrow down the text fields the search has to go though to make sure it is a relevant result from the database.
My table name is 'testing' then the text field column is called 'context' and the line number where it is located is called 'line_number'. Where the context text is associated with a specific line_number.
Right now my ranking code looks like this:
select line_number into lineLocation
from (
SELECT
testing.line_number,
ts_rank_cd(to_tsvector('english', testing.context),
to_tsquery('Cats & Dogs & Kids')) AS score
FROM Testing
) ranking
WHERE score >0
ORDER BY score DESC;
Return QUERY select * from lineLocation;
When I try to print out lineLocation as a return query, it works in reporting the new ranked line numbers 22,19,21,20,17,13 each returned in their own column.
My problem now is that I want to search each of those lines (22 ... 13) for a key word like "dog" and return its position
Obtaining the text for that by using:
select context into sample from testing
where testing.line_number = lineLocation;
If I try to just decrement the lineLocation in a loop like lineLocation -i
It goes out of order, and will eventually search context that is not relevant.
Is there any type of 'read next line' function I could use?
I am looking for a way to loop through the ranked result line numbers
EDIT I then go on to use a for loop where I want it to read through all of the rows of text in the column context from the ranked results
The problem I am having with this is that it only reads the first row of text in the column 'context' and I need it to look at all of the rows that are returned by the ranked search
Ended up creating a ranking function of its own, and inserting the results of that text search into another table with a serial increment column.
filled the values of the new table (ranked_results) with this code:
INSERT INTO ranked_results(sentence) VALUES (columnRanking());
I also had to create a function to delete/reset the columns in the new table upon insertion of more lines.
TRUNCATE table ranked_results RESTART IDENTITY;
