Toad for Oracle 12:
I'm working in a system that has an unfortunate limitation where an SQL query's FROM clause can only have up to 1000 characters (including spaces). This becomes a problem when the FROM clause has a lengthy subquery in it (> 1000 chars).
So, when writing SQL in Toad, I need a way to highlight the SQL in the FROM clause and count the characters in the highlighted text, including spaces.
Currently, I copy the text into MS Word and do a character count there. That works, but it would be better if I could do the character count right in Toad.
Question:
Does Toad 12 have SQL character count functionality?
As #SamM mentioned, the bottom panel/status bar shows the character count when I highlight text in the SQL editor window:

I need to extract each word (phrase) within a cell in google sheets and put each one under the other in a column (row for each one).
I have a regex code that works when testing it, but I cannot do it work in google sheet the same code. Any ideas?
You can just do
=SUBSTITUTE(A1," ",char(10))
or
=transpose(split(A1," "))
You don't really need regex for this. You can use Transpose and split methods of google sheets.
Example:
In sheets in A1 put your text then in B1 copy this =TRANSPOSE(SPLIT(A1," "))
Update: this answer does not meet all requirements as it puts all results in one cell.
The ASCII character numbers need to be used instead of \r\n that you would expect from other tools.
Carriage return has number 13 and line feed has number 10:
=REGEXREPLACE(A1, "\s", CONCAT(CHAR(13), CHAR(10)))
SAS while reading varbinary data from Amazon RDS is appending spaces at the end of the data.
proc sql;
select emailaddr from tablename1;
quit;
The column emailaddr is varbinary(20)
For example:
I inserted "XX#WWW.com ", but while reading from db, it is appending spaces equal to the length of the column.
Since the column length is 20 it is returning "XX#WWW.com " ( note the spaces appended. I cannot use the trim() function since this also removes spaces that might genuinely be part of the original inserted data.
How can i stop sas from appending these spaces?
For my program i need to get the exact data as present in database without any extra spaces attached.
That's how SAS works; SAS has only CHAR equivalent datatype (in base SAS, anyway, DS2 is different), no VARCHAR concept. Whatever the length of the column is (20 here) it will have 20 total characters with spaces at the end to pad to 20.
Most of the time, it doesn't matter; when SAS inserts into another RDBMS for example it will typically treat trailing spaces as nonexistent (so they won't be inserted). You can use TRIM and similar to deal with the spaces if you're using regular expressions or concatenation to work with these values; CATS and similar functions perform concatenation-with-trimming.
If trailing spaces are part of your data, you are mostly out of luck in SAS. SAS considers trailing spaces irrelevant (equivalent to null characters). You can append a non-space character in SQL, or translate the spaces to NBSPs ('A0'x) or something else, while still in SQL, or use quotes or something around your actual values - but whatever you do will be complicated.
I'm working with a huge DB2 table (hundreds of millions of rows), trying to select only the rows that are matched by this regular expression:
\b\d([- \/\\]?\d){12,15}(\D|$)
(That is, a word boundary, followed by 13 to 16 digits separated by nothing or a single dash, space, slash, or backslash, followed be either a non-digit or the end of the line.)
After much Googling, I've managed to create the following SQL:
SELECT idx, comment FROM tblComment
WHERE xmlcast(xmlquery('fn:matches($c,"\b\d([- \/\\]?\d){12,15}(\D|$)")' PASSING comment AS "c") AS INTEGER)=1
Which works perfectly, as far as I can tell... unless it finds a row with an illegal character:
An illegal XML character "#x3" was found in an SQL/XML expression or function argument that begins with string [...]
The data contains many illegal XML characters, and changing the data is not an option (I have limited read-only access, and there are far too many rows that would need to be fixed). Is there a way to strip out or ignore illegal characters, without first modifying the database? Or, is there a different way for me to write my query that has the same effect?
You will have to identify what are all the illegal XML characters that occur in your data. Once you know them, you can use the TRANSLATE() function to eliminate them during the pattern matching.
Say, you determine that all ASCII control characters (0x00 through 0x0F and 0x7F) may be present in the COMMENT column. Your query might then look like:
SELECT idx, comment FROM tblComment
WHERE xmlcast(xmlquery(
'fn:matches($c,"\b\d([- \/\\]?\d){12,15}(\D|$)")'
PASSING TRANSLATE(comment, ' ', x'01020304050607080B0C0F7F') AS "c")
AS INTEGER)=1
All legal XML characters are listed in the manual. 0x09, 0x0A and 0x0D are legal, so you don't need to TRANSLATE() them, for example.
Is there a way to search an Oracle database (some sort of regex I suspect) to find unknown characters (which often appear as □ □)?
There is no standard way to search over entire Oracle database. You would need a tedious script that walks over various types of Oracle objects in dba_objects, and then descends into each (for a trivial example if an object is a table you need to parse the columns, and if a column contains a character data, REGEXP_LIKE; but there are more types of objects, for example a package - do you want to search package's literals too?). I would instead make manually an explicit list of queries over tables and columns.
Try something like this:
select co11, ...
from tab1
where col1 like '%'||chr(9)||'%' -- ascii code for tab
or col1 like '%'||chr(20)||'%' -- ascii code for newline
--...
;
Here's the situation I'm in: We have a field in our database that contains a 3 digit number, surrounded by some text. This number is actually a PK in another table, and I need to extract this out so I can implement a proper FK relationship. Here's an example of what would currently reside in the column:
Some Text Goes Here - (305) Followed By Some More Text
So, what I'm looking to do is extract the '305' from the column, and hopefully end up with a result that looks something like this (pseudo code)
SELECT
<My Extracted Value>,
Original Column Text,
Id
FROM dbo.MyTable
It seems to me that using a Regex match in my query is the most effective way to do this. Can anybody point me in the right direction?
EDIT: We're using SQL Server 2005
RegExp in SQL is defined by a SQL-Standard but most databases implemented their own syntax, you should tell us the product name of your RDBMS ;)
This is based on Pranay's first answer that has since been changed.
DECLARE #NumStr varchar(1000)
SET #NumStr = 'Some Text Goes Here - (305) Followed By Some More Text';
SELECT SUBSTRING(#NumStr,PATINDEX('%[0-9][0-9][0-9]%',#NumStr),3)
Returns 305
Microsoft seems to suggest using a CLR assembly to do Regex pattern matching in SQL Server 2005.

Apart from LIKE (which is not going to solve your problem) I don't know of a built-in pattern matching functionality in SQL Server 2005 (that is, more advanced than simple string searches).
Just after I implemented a solution in Postgres, I see you are using SqlServer... Just for the records, then, with a regex that extracts data in parenthesis.
Postgresql solution:
create table main(id text not null)
insert into main values('some text (44) other text');
insert into main values('and more text (78) and even more');
select substring(id from '\\(([^\\(]+)\\)') from main
The only way to access RegEx-type functions in SQL 2005 (and probably 2008) is by writing (or downloading) and using CLR functions.
If all the strings are always formatted in such a way as you can identify the specific numbers you want, you can do something like the following. This is based on the (big) assumption that the first set of parenthesis found in the string contains the number that you want.
/*
CREATE TABLE MyTable
(
MyText varchar(500) not null
)
INSERT MyTable values ('Some Text Goes Here - (305) Followed By Some More Text')
*/
SELECT
MyText -- String
,charindex('(', MyText) -- Where's the open parenthesis
,charindex(')', MyText) -- Where's the closed parenthesis
,substring(MyText
,charindex('(', MyText) + 1, charindex(')'
,MyText) - charindex('(', MyText) - 1) -- Glom it all together
from MyTable
Awkward as heck (because SQL has a pathetically limited set of string manipulation functions), but it works.
