SQL query to retrieve only numbers to a string variable

Dear all Experts,

I have a requirement in one of my projects where I need to extract only the numbers present in the variable.

for example:

BANK_ACCOUNT_NUMBER = 12345-67890';

BANK_ACCOUNT_NUMBER = 12345 67890';

BANK_ACCOUNT_NUMBER = "123.456.7890";

BANK_ACCOUNT_NUMBER = 123-A456BC7890D';

In all these cases, I need to retrieve only numbers such as BANK_ACCOUNT_NUMBER = 1234567890 and I am looking for SQL query only.

Please suggest me the query how to extract numeric values from varchar variable.

Thank you

Knockaert

  select regexp_replace('123-A456BC7890D','[^0-9]') from dual;

See you soon,.

Manik.

Specifically, the two simple solutions provided were:

1 using the row_number, entitled Oracle ranking based on descending order of the inside telephone each empnum group. And finally selects the lines which has least rank (of least since that order is descending for phone).

SQL > column alternatecontact format A20;

SQL >

SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

2 from (SELECT a.*, row_number() over r (PARTITION BY empnum ORDER BY phone / / DESC))

3 FROM xxc_contact one)

4. WHEN r = 1

/

EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE

2. with the help of MAX, Oracle automatically assigns the maximum phone for all the rows in each group of empnum. And finally selects the rows with the maximum phone. Order by clause is omitted here intentionally. You can find out why.

SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

2 (SELECT a.*, MAX (phone) over (PARTITION BY empnum) rn FROM xxc_contact one)

3 WHERE phone = rn

I thought it was a simple group of problem?
```

FROM MC_Maintenance MC INNER JOIN Machine M ON MC.MC_ID = M.MC_ID
GROUP BY M.EquipID, MC.MC_ID

Based on the data, the user ID 39 must be found, since it's been sitting since 09:36-10:35, which is continuous 1 hour.
Any guidance how to do using SQL query will be of great help and appreciation.
Thank you very much
Kind regards

So what exactly is wrong with the request that I already gave you?

Just to remind one untested (because of lack of insert statements) rewrite according to your new data:

with grp as)

Select

username

UserRecognizedActivityID activity

starttime

starttime + endetime + 1

row_number() over (partition by order of starttime userid)

-ROW_NUMBER() over (partition of userid, UserRecognizedActivityID order of starttime)

RN

of activity_log

)

Select

username

min (starttime) starttime

max (endtime) endtime

max (activity) activity

GRP

Group userid, rn

with round (max (endtime) - min (starttime) * 24 * 60) > = 59

SQL query to retrieve the same record because no. boxes

Hi all
I have a table of Bill XXINV.
the columns are
INVH_NO INVH_ITEM_CODE INVH_QTY INVH_BOXES
1122                XXITEM1                    1                    5
1123                XXITEM2                     2                   6
I can do a sql query so that I can retrieve the same records repeated as number INVH_BOXES.
Select * from XXINV
where invh_no = 1122
output:
INVH_NO INVH_ITEM_CODE INVH_QTY INVH_BOXES
1122                XXITEM1                    1                    5
Desired output:
INVH_NO INVH_ITEM_CODE INVH_QTY INVH_BOXES
1122                XXITEM1                    1                    5
1122                XXITEM1                    1                    5
1122                XXITEM1                    1                    5
1122                XXITEM1                    1                    5
1122                XXITEM1                    1                    5
or
INVH_NO INVH_ITEM_CODE INVH_QTY INVH_BOXES
1122 XXITEM1 1 1 of 5
1122 XXITEM1 1 2 of 5
1122 1 3 5 XXITEM1
1122 XXITEM1 1 4 of 5
1122 XXITEM1 1 5 of 5
Please suggest. Like I need to print each line in a single page to stick them on boxes so that packaging.
Kind regards
Afzal.

Just add INVH_ITEM_CODE to the connection by the clause.

Select invh_no

invh_item_code

invh_qty

to_char (, 'fm99') | 'from ' | TO_CHAR (invh_boxes, 'fm99') invh_boxes

of xxinv

where invh_no = 1122

connect

by level<=>

and prior invh_item_code = invh_item_code

and prior sys_guid() is not null

Help me with SQL Query to retrieve data from a view
Hello Guru,

I need help in my sql query.
I use SQL TeraData.
I want an Oracle result in the following form-

I wrote the query as where - TIME_PERIOD, RQST_TYPE_DM and DEMAND_SUMMARY_FCT are the points of view and I extract the data from the views only.

Select NVL (CA. TIME_PERIOD. PERIOD_CD, 'Total') THAT year.
COUNT (CASE WHEN CA. RQST_TYPE_DM. RQSTTYP_DESC Like '% of Break' THEN 1 END) as BreakFix
COUNT (CASE WHEN CA. RQST_TYPE_DM. RQSTTYP_DESC as 'N/a', 1 END) by n/a

WHEN CA. DEMAND_SUMMARY_FCT. RQSTTYP_ID = '1' then 1
END) = 1
GROUP BY ROLLUP (CA. TIME_PERIOD. PERIOD_CD)

After executing the query, I get the following error:
3076: syntax Error: Data Type 'Time' does not match a defined Type name.
:( Kindly help me with this and let me know where I'm wrong... Please.
Messages indicates something wrong with your data... It would seem that the data does not match your format mask.

Looking for a SQL query to retrieve callvariables + ECC to a RESULTS of SCRIPT EXECUTE (translation VRUS)

Hi team,

I'm looking for a SQL query check data (ECC + CallVariable) due to a RESULT of SCRIPT EXECUTE when you ask an external VRU with a translation route to VRU with a 'run external Script '.

In my view, that the data are analyzed between the termination call detail + termination call Variable.

If you have already such a SQL query I would be very grateful to have.

Thanks and greetings

Omar,

respectfully, shorten the interval of a day might not be an option for a history report ;-)

I recommend to take a look at the following SQL query:

DECLARE @dateFrom DATETIME, @dateTo DATETIME

SET @dateFrom = ' 2014-01-24 00:00:00 '

SET @dateTo = ' 2014-01-25 00:00:00 '

SELECT

TCV. DateTime,

TCD. RecoveryKey,

TCD. RouterCallKeyDay,

TCD. RouterCallKey,

VME. EnterpriseName AS [ECVEnterpriseName],

TCV. ArrayIndex,

TCV. ECCValue

OF Termination_Call_Variable tcv

JOIN THE

(SELECT RouterCallKeyDay, RouterCallKey, RecoveryKey IN Termination_Call_Detail WHERE DateTime > @dateFrom AND DateTime)< @dateto)="">

THE tcv. TCDRecoveryKey = tcd. RecoveryKey

LEFT OUTER JOIN Expanded_Call_Variable VME ON tcv. ExpandedCallVariableID = VME. ExpandedCallVariableID

WHERE the tcv. DateTime > @dateFrom AND tcv. DateTime<>

With variables, you can set up your code (for example, you could write SET @dateFrom =? and let the calling application to fill in the DateTime for you).

In addition, join two large tables with all the lines, as you did (TCD - TCV) is never a good option.

Another aspect to consider: all the ECC is actually arrays (always), is not good to leave aside the index value (tcv. ArrayIndex).

SQL query to retrieve all instances of a model within the column
I had an obligation to build a query for the scenario below. Pls help to troubleshoot.

Scenario.
Table 1 has two columns < number > col1 and col2 < CLOB >

Row2-col1
2

Col2 < Clob > has the following values

Output:
A1234
A1238

I want a loop must be created and check until the end of the column.
Pls help me with the query. It will be useful.

Thank you

You can simulate loops with sql functions as the clause-type (since 10 g) or recursive subquery (since 11.2).
Generally in this forum link it by the approach will be proposed.
The depth will be the number of occurrences of your model and the level will be the real occurency.
So just search inthi forum for an abundance of examples
```
select regexp_substr(col2, 'A[0-9]{4}', 1, level)
from tabel1
connect by
level <= regexp_count(col2,'A[0-9]{4}')
```
regexp_count since 11. ?

SQL Query to retrieve data in XML format with several levels

Hello

I'm looking to help generate XML from Oracle database. The request must contain many levels of sub...

For example.
Create table inventory

The output should be also present below. The data must be multiple values for each item.

< name productname = 'Seat' >
< details > red color < / details >
< details > 5 seats < / details >

Please share your ideas by retrieving data in the XML structure using SQL or PL/SQL for oracle 10 g.

SQL query to extract the part of a string.

Could someone help me with a SQL to retrieve the section highlight of my channel?
ABC_DEF_CDT_20140512140005_20140504030420_C20140512.055505. 20140522.070022.csv
BTW, the format of the string is less to:
< EMS_NAME > _CDT_ < CollectionDateTime > _ < EMS_timestamp > < StartDate > _C. < StartTime >. < EndDate >]. < EndTime> .csv
Kind regards
B
```
One way would be

SQL> with t
  2  as
  3  (
  4  select 'ABC_DEF_CDT_20140512140005_20140504030420_C20140512.055505.20140522.070022.csv' str
  5    from dual
  6  )
  7  select ltrim(regexp_substr(str, 'C[[:digit:]]{8}\.[[:digit:]]{6}'), 'C') str
  8    from t;

STR
---------------

SQL query to represent the data in the graph bar

Hello
JDev 11.1.1.5.0
We must create a dashboard to track the translation. We have created the ADF table with buttons 'Create', 'Update' and 'Delete' to manipulate the table.
Our DB table structure is
File_id (PK), File_Name, ToSpanish - ARE (YES/NO), beginning of the ToSpanish, ToChina(YES/No), ToChina-Date... etc.
Once the translated file required language then user must update the DB table using the button "Update".
So far, we have implemented the requirement above.
We need represent the status of the translation in the graph bar with the language as X access and file count get access Ex: Spanish-100 China - 200 files files
Please suggest the sql query to retrieve the necessary info from the DB table that can be represented in the graph bar. Also, it would be great, if you can provide a pointers to create a bar chart.
Thanks in advance,
MSR.

If you set your major increment and minor than 1, then you won't not show decimal points. You can try setting these 10 or 100 to reach your goal.

                      SELECT 102,'AAA' FROM dual UNION ALL
                      SELECT 103,'AAA' FROM dual UNION ALL
