Recently I have posted a question, it contains some syntax error, now the code is running without error, thanks to #Arulkumar.
But now I am facing one more problem, data from excel sheet is storing properly on to SQL Server database, but when I press refresh button or if I go to that link again in my application, data is repeating in the database. Means again it is retrieving values from excel and storing same data again in the database.
How can I avoid data repetition. Can any one please help me to solve this issue? Code and excel sheet sample is there in the above mentioned link.
You need MERGE statement
request.query('MERGE [mytable] as target USING (SELECT SalesPersonID, TerritoryID FROM OPENROWSET(' +
'\'Microsoft.ACE.OLEDB.12.0\', \'Excel 12.0;Database=D:\\sample\\test\\data\\1540_OPENROWSET_Examples.xls;HDR=YES\', ' +
'\'SELECT SalesPersonID, TerritoryID FROM [SELECT_Example$]\')' +
' ) as source' +
' ON target.SalesPersonID = source.SalesPersonID' +
' WHEN MATCHED THEN UPDATE SET TerritoryID = source.TerritoryID' +
' WHEN NOT MATCHED THEN INSERT (SalesPersonID, TerritoryID) VALUES (source.SalesPersonID, source.TerritoryID);'
,function(err,recordset){
if(err) console.log(err)
It will update TerritoryID if there is already row with same SalesPersonID and insert row if there is no matches in mytable.
If you need join on both fields change this:
ON target.SalesPersonID = source.SalesPersonID
On this:
ON target.SalesPersonID = source.SalesPersonID AND target.TerritoryID = source.TerritoryID
And after that - remove this string because it doesn't need anymore:
'WHEN MATCHED THEN UPDATE SET TerritoryID = source.TerritoryID' +

I am trying to build one stored procedure in snowflake which will
i. Delete existing records from dimension table.
ii. Insert the records into the dimension table from corresponding materialized view.
iii. Once the data is inserted, record the entry into a config table.
First two are running fine, third one is not working, code below
Table DIM_ROWCOUNT
CREATE TABLE ANALYTICSLAYER.AN_MEDALLIA_P.DIM_ROWCOUNT
(
"TABLE_NAME" VARCHAR(500),
"VIEW_NAME" VARCHAR(500),
"TABLE_ROWCOUNT" VARCHAR(500) ,
"VIEW_ROWCOUNT" VARCHAR(500),
"LOADDATE" timestamp
)
The SP has parameter as SRC_TABLE_NAME which should be loaded for column : TABLE_NAME,
VIEW_NAME will be derived inside code.
TABLE_ROWCOUNT and VIEW_ROWCOUNT will be calculated within the code.
I need to have a multi line query for insertion.
How to create the insert statement multiline?
var config_details = `INSERT INTO DBNAME.SCHEMANAME.TABLENAME
SELECT '${VAR_TABLE_NAME}','${VAR_VIEW_NAME}','${VAR_TABLE_ROW_COUNT}','${VAR_VIEW_ROW_COUNT}',getdate();`
var exec_config_details = snowflake.createStatement( {sqlText: config_details} );
var result_exec_config_details = exec_config_details.execute();
result_exec_config_details.next();
Any help in appreciated.
I tend to write complex SQL statements in a javascript SP by appending each line/portion of text to the variable, as I find it easier to read/debug
Something like this should work (though I haven't tested it so there may be typos). Note that to get single quotes round each value I am escaping them in the code (\'):
var insert_DIM_ROWCOUNT = 'INSERT INTO DBNAME.TEST_P.DIM_ROWCOUNT ';
insert_DIM_ROWCOUNT += 'SELECT \'' + SRC_TABLE_NAME + '\', \'' + VIEW_NAME + '\', \'';
insert_DIM_ROWCOUNT += TABLE_ROWCOUNT + '\', \'' + VIEW_ROWCOUNT + '\', ';
insert_DIM_ROWCOUNT += GETDATE();
I then test this to make sure the SQL statement being created is what I want by adding a temporary line of code, after this, to just return the SQL string:
return insert_DIM_ROWCOUNT;
Once I'm happy the SQL is correct I then comment out/delete this line and let the SQL execute.
I need to copy data from an old database to a newer one.
Both of these databases have a user setup table with the primary key of "USER ID".
The problem is, in the old database the users didn't have the domain in the name, but in the new one they have.
Example:
Primary Key old DB: USER1
Primary Key new DB: DOMAIN\USER1
This prevents a standard WHERE clause to update the correct user because it can't find it due to the domain being added.
My code:
'FROM [' + #src_DB + '].dbo.[' + #src_table + '] as src '
'WHERE [' + #dest_DB + '].dbo.[' + #dest_table + '].[User ID] = ' + #domain_name + 'src.[User ID]'
printing the result:
WHERE [Destination_DB].dbo.[Destination_Table].[User ID] = DOMAIN\src.[User ID]
The problem is it doesn't add the DOMAIN to the value but rather to the statement...
How can I add the Domain to the actual value of src.[User ID]?
I think there's a dot missing, and you should use QUOTENAME
'WHERE ' + QUOTENAME(destination_table) + '.[User ID] = ' + QUOTENAME(#domain) + '.' + QUOTENAME(source_table) + '.[User ID]'
Whenever you create a SQL statement dynamically it's a good idea to print it out, copy it into a new query window and check for syntax errors...
UPDATE You: Yes, both databases are in the same server
An object can be (fully) specified with
ServerName.DatabaseName.Schema.ObjectName
A table's column would add one more .ColumnName
When both objects live on the same server you can let the first part away.
Objects of the same database let this part away.
Objects of the default schema might be called with the ObjectName alone.
But if you state a DatabaseName you must also state a SchemaName!
Use QUOTENAME() to add the brackets and add just the dots via string concatenation (or use CONCAT()-function).
UPDATE 2 Did I get this wrong completely?
After you comment I think I understand it now: You want to compare the values of both [USER ID] columns, but the new is DOMAIN\MyUserId while the older was just MyUserId.
You have two approaches
Add the Domain\ as string to the value of [User ID]
Use SUBSTRING([User ID],CHARINDEX('\',[UserID])+1,1000) to cut the newer value down to the naked value of [User ID]
For the first something like this
'WHERE [' + #dest_DB + '].dbo.[' + #dest_table + '].[User ID] = ''' + #domain_name + ''' + src.[User ID]'
The second is quite clumsy with dynamically created SQL...
I know there are a few about similar topics on here but I can't find one related to my issue, this is it:
I have a table with an ID Column and a QRCode column. each time an item is added the primary key auto increments. The QRCode will scan in to be like the following:
"http://somewebsite.com/12345/987654321"
i want to be able to remove the "http://somewebsite.com/" from the string, I know how to do this in C# however I am unsure of how to do this in Sql Server. any guidance would be great, thanks
Regular formats are like the following, and used in the example below.
"http://somewebsite.com/12345/456564654"
"http://somewebsite.com/12345/989886765"
"http://somewebsite.com/12346/987654321"
the query returns the following results:
SELECT
REPLACE
(
REPLACE(QRCode, 'http://somewebsite.com/', '')
,'/', ' '
) AS QRCode
FROM
QRTable
WHERE
QRCode LIKE '%http://somewebsite.com/%'
"12345 456564654"
"12345 989886765"
"12346 987654321"
Now i need to update the table with those new results however as there's 3 results, i get the error message "Subquery returned more than 1 value". is there a way to replace the selected values in the table with the ones that exist based on the primary key field?
**Removed previous example
A more complete answer based on your updated question. This removes the first portion of the URL as well as the trailing / so that you get your desired output.
DECLARE #Variable VARCHAR(50)
SET #Variable = 'http://somewebsite.com/12345/456564654'
SET #Variable =
REPLACE
(
REPLACE(#Variable, 'http://somewebsite.com/', '')
,'/', ' '
)
PRINT #Variable
Output = 12345 456564654
Looking at your SQL statement you want this:
SELECT
REPLACE
(
REPLACE(QRCode, 'http://somewebsite.com/', '')
,'/', ' '
) AS QRCode
FROM
QRTable
WHERE
QRCode LIKE '%http://somewebsite.com/%'
I wondered if anyone could help me with something I am having some issues with.
TB_SAMPLES contains a field called Notes. This field needs to be updated with the contents of my reference table, SUNCORE_NOTES_UPDATE. I need to add this new data as a prefix to any existing notes.
I have been able to select the values as I would like them to be displayed but I am not able to undertake the update. My 'select' code is below:
select traxx_supportb.[jlr_sql].[suncore_notes_update].notes + ' ' +
tb_samples_nw.notes as fullnotes
from tb_samples_nw, traxx_supportb.[jlr_sql].[suncore_notes_update]
where tb_samples_nw.id = traxx_supportb.[jlr_sql].[suncore_notes_update].id
Can anyone help me with the SQL required to add the contents to TB_SAMPLES.NOTES from SUNCORE_NOTES_UPDATE.NOTES as a prefix?
Thanks very much all!
J
UPDATE t1
SET notes = t2.notes + ' ' + t1.notes
FROM tb_samples_nw t1
JOIN traxx_supportb.[jlr_sql].[suncore_notes_update] t2
ON t1.id = t2.id
Try this:
update tb_samples_nw set notes = IsNull(suncore_notes_update.notes,'')+' '+IsNull(notes,'')
from traxx_supportb.[jlr_sql].[suncore_notes_update]
where tb_samples_nw.id = traxx_supportb.[jlr_sql].[suncore_notes_update].id
You can use an INNER JOIN with an UPDATE. It also makes it cleaner to alias the tables:
UPDATE s
SET s.notes = u.notes
+ ' '
+ s.notes
FROM tb_samples_nw s
INNER JOIN traxx_supportb.[jlr_sql].[suncore_notes_update] U
ON S.id = U.id
Be aware that the original note will be irreversibly modified, meaning that if you run the query again it will prepend the note again.
I want to update on a linked server the result of a query as well from a linked server.
The first sql snippet gives me the value to be updated:
SELECT mmdb_vessel.IMONo, mmdb_vessel.DeathDate
From OPENQUERY(MMDB, 'SELECT FunctionalLocation, IMONo, VesselStatus, CONVERT(VARCHAR(10), DeathDate, 102) AS DeathDate
FROM VESSEL
WHERE VESSEL.VesselStatusID <> 42 AND VESSEL.DeathDate is not null') as mmdb_vessel
, eb_all_v
WHERE
eb_all_v.IMO_No = mmdb_vessel.IMONo
AND eb_all_v.status = 'in service'
the second is actually what I'm not able to implement, it should show what I want to achieve:
UPDATE EPI2..EPI.PLANT
SET KIND_OF_LIQUIDATION_NO = 1
, LIQUIDATION_DATE = [result from snippet above].DeathDate
Where EPI2..EPI.PLANT.IMONo = [result from snippet above].IMONo
I'm not so sure if my explanation is sufficient, please feel free to ask for additional information!
Thanks, already in advance,
Werner
I would recommend to select the data from the remote server first and store the required data e.g. in a temptable, because LinkedServer and updates can have some sideeffects (e.g. performing a tablescan on the remote table, altough you would not expect it if an updaet is involved, etc) - but this depends on your exact usage/scenario.
Select data you need to update
SELECT * INTO #tmpTable FROM LINKEDSERVER.EPI.dbo.PLANT WHERE ....
Perform the update on local server
UPDATE EPI2..EPI.PLANT SET KIND_OF_LIQUIDATION_NO = 1, LIQUIDATION_DATE = t.DeathDate FROM #tmpTable t INNER JOIN EPI2..EPI.PLANT p on t.IMONo = p.IMONo
