I have two variables:
One is varchar and one is int, I am not sure how to write a while loop using casting so that it will show the following: for example if the while loop is 5 then the result should be
Meter 1
Meter 2
Meter 3
Meter 4
Meter 5.
I have this code, but it is not running (cannot convert varchar to int) even when i do the casting it does not work.
DECLARE #Name varchar (20) = 'Meter',
#MeterNumber int = 1
WHILE (#MeterNumber < 5)
BEGIN
PRINT #Name + ' ' + #MeterNumber
SET #MeterNumber = #MeterNumber + 1
END
This should do the trick: cast the MeterNumber to a varchar when you print it.
DECLARE #Name varchar (20) = 'Meter',
#MeterNumber int = 1
WHILE (#MeterNumber <= 5)
BEGIN
PRINT #Name + ' ' + cast(#MeterNumber as varchar(20))
SET #MeterNumber = #MeterNumber + 1
END
EDIT:
For example I want to declare a third variable that would store each
iteration. Meter 1, Meter 2... but I am not sure where to place it!
DECLARE #Name varchar (20) = 'Meter',
#MeterNumber int = 1 ,
#OutPut varchar(max) =''; -- this can get biiiig.
WHILE (#MeterNumber <= 5)
BEGIN
SET #Output = #Output + #Name + ' ' + cast(#MeterNumber as varchar(20)) + ','
PRINT LEFT(#Output, len(#Output) - 1)
SET #MeterNumber = #MeterNumber + 1
END
Try this one (without LOOP) -
DECLARE
#Name VARCHAR(20) = 'Meter'
, #MeterNumber INT = 5
, #OutPut VARCHAR(MAX) = ''
SELECT #OutPut = STUFF((
SELECT CHAR(13) + #Name + ' ' + CAST(sv.number AS VARCHAR(5))
FROM [master].dbo.spt_values sv
WHERE sv.[type] = 'p'
AND sv.number BETWEEN 1 AND #MeterNumber
FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)'), 1, 1, '')
PRINT #OutPut

I have two databases in SQL Server 2014 Express, since a few days ago I am unifying both databases in such a way that there is only one left.
When I have this new database I must pass it to Azure (I don't have any experience using this technology), however, I am doing tests on my local server, so far I have created the whole scheme but I must fill out all the tables to perform tests with my application.
There are 313 tables of which many have more than 200,000 records, my question is, what is the best way to populate the database?
Because at this moment I want to test my local machine, I could fill in the tables through Tasks> Generate Script> Advanced Options (Include only data) but this information will change the day when the migration to Azure is done, therefore I must Do the same process.
So, is it possible to create an INSERT SELECT script so that it does not include records one by one and is as dynamic as possible? For example, you would have to generate an INSERT INTO similar to this:
SET IDENTITY_INSERT [SchemaX].[TableA] ON ;
INSERT INTO [SchemaX].[TableA]
(
[id]
,[fieldA]
,[fieldB]
,[fieldC])
SELECT
[id]
,[fieldA]
,[fieldB]
,[fieldC]
FROM [server].[dbname].[SchemaX].[TableA]
SET IDENTITY_INSERT [SchemaX].[TableA] OFF ;
Some tables have IDENTITY enabled so you would have to recognize which tables are like this and use SET IDENTITY_INSERT when inserting. This way you would have to link the production server and insert the information into the local server.
If there are suggestions or recommendations about another way you are welcome

I want to find a credit card numeric value in a sql string.
for example;
DECLARE #value1 NVARCHAR(MAX) = 'The payment is the place 1234567812345678'
DECLARE #value2 NVARCHAR(MAX) = 'The payment is the place 123456aa7812345678'
DECLARE #value3 NVARCHAR(MAX) = 'The payment1234567812345678is the place'
The result should be :
#value1Result 1234567812345678
#value2Result NULL
#value3Result 1234567812345678
16 digits must be together without space.
How to do this in a sql script or a function?
edit :
if I want to find these 2 credit card value.
#value4 = 'card 1 is : 4034349183539301 and the other one is 3456123485697865'
how should I implement the scripts?
You can use PathIndex as
PATINDEX('%[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]%', yourStr)
if the result is 0 then it doesnt containg 16 digits other was it contains.
It can be used withing a Where statement or Select statement based on your needs
You can write as:
SELECT case when Len(LEFT(subsrt, PATINDEX('%[^0-9]%', subsrt + 't') - 1)) = 16
then LEFT(subsrt, PATINDEX('%[^0-9]%', subsrt + 't') - 1)
else ''
end
FROM (
SELECT subsrt = SUBSTRING(string, pos, LEN(string))
FROM (
SELECT string, pos = PATINDEX('%[0-9]%', string)
FROM table1
) d
) t
Demo
DECLARE #value1 NVARCHAR(MAX) = 'card 1 is : 4034349183539301 and the other one is 3456123485697865'

BEGIN
SELECT #Candidate = SUBSTRING(#value1, #Count, 1)
IF #Candidate != ' '
AND ISNUMERIC(#Candidate) = 1
BEGIN
SET #cNum = #cNum + 1
SET #result = #result + #Candidate
END
ELSE
BEGIN
SET #cNum = 1
SET #result = ''
END
IF #cNum > 16
BEGIN
SELECT #result 'Credit Number'
END
SET #Count = #Count + 1
END
There you go kind sir.
DECLARE
#value3 NVARCHAR(MAX) = 'The payment1234567812345678is the place',
#MaxCount int,
#Count int,
#Numbers NVARCHAR(100)
SELECT #Count = 1
SELECT #Numbers = ''
SELECT #MaxCount = LEN(#value3)
WHILE #Count <= #MaxCount
BEGIN

SELECT #Numbers = #Numbers + SUBSTRING(#value3,#Count,1)
SELECT #Count = #Count + 1
END
PRINT #Numbers
You can make this as a function if you are planning to use it a lot.
I don't have much experience with dynamic procedures so the following was only an attempt.
The only part that is actually dynamic here is the table name which I tried to create by combining the fix part "MOC_" and the variable part #level.
Can someone tell me what I have to change here to make this work ?
The error I get when executing this points to the IF NOT EXISTS part:

#itemID is an int. Because it is used in the expression, everything else must be converted to a number, including your SQL text.
Convert #itemID (and other numbers) to nvarchar before concatenating it into the query:
SET #sql = N'IF NOT EXISTS
(
SELECT *
FROM MOC_' + #level + '
WHERE itemID = ' + cast(#itemID as nvarchar(30)) + ...
I have several occurrences of differences strings in the columns, like this example
'dsasdasdsd'+'ewewewew'+'45454545'+(avg('uuuuuuu'))
I need to split this string into several columns with the substrings that are between
aphostropes
like this:
Column 1 = dsasdasdsd
Column 2 = ewewewew
Column 3 = 45454545
Column 4 = uuuuuuu
The numbers of apperances are random, thefore the length of the original column is also not fixed (from 50 char to > 1000)
DECLARE #InStr VarChar(1000) = '''dsasdasdsd''+''ewewewew''+''45454545''+(avg(''uuuuuuu''))'''
DECLARE #intStart INT = 0
DECLARE #intEnd INT = 1
DECLARE #ColNo INT = 1
DECLARE #MyString VARCHAR(2000)
DECLARE #SelectString VARCHAR(8000) = 'SELECT '
WHILE(#intStart < LEN(#InStr) )
BEGIN
SELECT #intStart = CHARINDEX(CHAR(39), #InStr, 0) + 1
SELECT #intEnd = CHARINDEX(CHAR(39), #InStr, #intStart)
SELECT #SelectString = #SelectString + CHAR(39) + SUBSTRING(#InStr, #intStart, #intEnd - #intStart) + CHAR(39) + ' As [Column ' + CAST(#ColNo As Varchar) + '],'
SELECT #InStr = SUBSTRING(#InStr, #intEnd + 1, LEN(#InStr)-#intEnd )
SET #ColNo = #ColNo +1
END
SELECT #SelectString = LEFT(#SelectString, Len(#SelectString) -1)
EXEC (#SelectString)
I have been playing with this and this does run but unfortunately I don't have time right now to carry on with it but maybe you can improve on this?
HTH
You can try this:
create table tSqlStrings (sText nvarchar(1000))
insert tSqlStrings values('''dsasdasdsd''+''ewewewew''+''45454545''+(avg(''uuuuuuu''))')
create table tResults (
sColumn1 nvarchar(1000)
,sColumn2 nvarchar(1000)
,sColumn3 nvarchar(1000)
,sColumn4 nvarchar(1000)
)
and
DELETE tResults
DECLARE #sText nvarchar(1000) = (
SELECT
sText
FROM
tSqlStrings
)
DECLARE #lBegin int = CHARINDEX('''',#sText)
DECLARE #lEnd int = charindex('''',
substring(#sText,
CHARINDEX('''',#sText)+1,
len(#sText)))
DECLARE #sText0 nvarchar(1000)
DECLARE #sColumn1 nvarchar(1000)
DECLARE #sColumn2 nvarchar(1000)
DECLARE #sColumn3 nvarchar(1000)
DECLARE #sColumn4 nvarchar(1000)
DECLARE #iCnt int = 1
while #iCnt<=4
--(0<len(#sText) and 0<#lBegin and 0<#lEnd)
BEGIN
SET #sText0 = substring(#sText,#lBegin+1,#lEnd-2)
IF #iCnt=1 begin SET #sColumn1=#sText0 end
IF #iCnt=2 begin SET #sColumn2=#sText0 end
IF #iCnt=3 begin SET #sColumn3=#sText0 end
IF #iCnt=4 begin SET #sColumn4=#sText0 end
set #sText = substring(#sText,#lBegin + #lEnd+2,len(#sText))
SET #lBegin = CHARINDEX('''',#sText)
SET #lEnd = charindex('''',
substring(#sText,
CHARINDEX('''',#sText)+1,
len(#sText)))
SET #iCnt = #iCnt+1
END
INSERT
tResults (sColumn1,sColumn2,sColumn3,sColumn4)
VALUES (#sColumn1,#sColumn2,#sColumn3,#sColumn4)
SELECT * FROM tResults

You will be able to achieve this using CHARINDEX() and SUBSTRING()
Following example shows for splitting to 2 columns. When it has more columns, query will be get little more complicated. However, you can follow this to build your query.
SELECT OriginalColumn
, SUBSTRING(OriginalColumn, 1,CHARINDEX('x',OriginalColumn,1)-1) AS Column1
, SUBSTRING(OriginalColumn, CHARINDEX('x',OriginalColumn,1) + 1 ,CHARINDEX('x',OriginalColumn,CHARINDEX('x',OriginalColumn,1)-1)) AS Column2
FROM YourTable
I have used "x" as the delimiter in the example. Following is a sample result
try this:
declare #delim char
set #delim = ''''
declare #str nvarchar(max)
declare #substr nvarchar(max)
declare #newstr nvarchar(max)
declare #tmpTable table (partStrings nvarchar(max))
declare #count int
set #count = 0
select #str = <***Your String***>
while(charindex(#delim,#str) != 0)
begin
set #count = #count + 1
Select #substr = substring(#str,1,charindex(#delim,#str)-1)
if((#count % 2) = 0)
begin
insert into #tmpTable values(#substr)
end
Set #newstr = substring(#str,charindex(#delim,#str)+1,len(#str)-charindex(#delim,#str))
set #str = #newstr
end
select partStrings from #tmpTable
