If i have a comma separated list of values:
A1,B2,B3
How do i pass this into a variable and then form it into an SQL IN statement.
DECLARE #DATE AS VARCHAR(50)
SELECT #DATE = CONVERT(VARCHAR(8), Getdate(), 112)
--PRINT #DATE
DECLARE #TIME AS VARCHAR(50)
--PRINT TIME
SELECT #TIME = Replace(CONVERT(VARCHAR(5), Getdate(), 108), ':', '')
DECLARE #ID AS VARCHAR(50)
SELECT #ID = Replace(W0128001, 32322, 32323, 3232323, 2323232, ',', ',')
--PRINT #ID
DECLARE #QUERY NVARCHAR(MAX);
SET #QUERY = 'SELECT * INTO BACKUPTABLE_' + #DATE + #TIME
+ '
FROM TABLE
WHERE ID IN (' + '''' + #ID + ''')'
--EXEC #query
PRINT #QUERY
I have tried to do a replace above but i want it so that an end user can PASTE into the values and my script will take care of the commas and properly form it. It should also strip out the last commas from the end.
My output needs to read:
SELECT * INTO BACKUPTABLE_201606061503
FROM TABLE
WHERE ID IN ('W0128001','32322','32323','3232323','2323232')
For one thing, you don't surround it with single quotes:
SET #QUERY = 'SELECT * INTO BACKUPTABLE_' + #DATE + #TIME + '
FROM TABLE
WHERE ID IN (' + #ID + ')';
There are other ways to pass comma-delimited values to a SQL statement, including using a split() function or XML.
CREATE PROCEDURE [dbo].[CreateBackupTable]
#ID varchar(100) = NULL
AS
BEGIN
SET NOCOUNT ON;
DECLARE #DATE VARCHAR(50)= CONVERT(VARCHAR(8), Getdate(), 112);
DECLARE #TIME VARCHAR(50) = Replace(CONVERT(VARCHAR(5), Getdate(), 108), ':', '')
declare #xml xml,#SQL NVARCHAR(MAX);
set #xml = N'<root><r>' + replace(#ID,',','</r><r>') + '</r></root>'
SET #SQL = N' SELECT * INTO ' + QUOTENAME('BACKUPTABLE_' + #DATE + #TIME)
+ N' from TableName '
+ N' where ID IN (
select r.value(''.'',''varchar(max)'') as item
from #xml.nodes(''//root/r'') as records(r)
)'
exec sp_executesql #sql
, N'#ID varchar(100), #xml XML'
, #ID
, #Xml
END

I am trying to loop through a temp table variable that contains a list of table names. I want to simply count the rows in each table where a DateTracked column is greater than 30 days. I am having trouble dynamically changing the FROM #tblName variable to store the record count and then insert it into my tracking table. Eventually I will use a cursor to loop through each, but I just want to get this logic down first for a single table. Here is my test code:
DECLARE #tblName as NVARCHAR(MAX)
DECLARE #q as NVARCHAR(MAX)
SET #q = 'Select Count(DateTracked) FROM Audit.' + #tblName + ' WHERE DateTracked > DATEADD(dd, -30, CAST(GETDATE() as date))'
--DECLARE #tblNameTable TABLE
--(
-- tableName NVARCHAR(MAX)
--)
--INSERT INTO #tblNameTable VALUES (N'myTestTable')
DECLARE #ExpectedRecordsToMove AS TABLE (col1 int)
INSERT INTO #ExpectedRecordsToMove EXECUTE sp_executesql #q, N'#tblName nvarchar(500)', #tblName = 'myTestTable'
SELECT * FROM #ExpectedRecordsToMove
Found solution.
DECLARE #tblName as NVARCHAR(MAX) = 'tblAutoDispatch_DispatchStatus_Map_Tracking'
DECLARE #q as NVARCHAR(MAX) = 'SELECT Count(DateTracked) FROM Audit.' + #tblName + ' WHERE DateTracked > DATEADD(dd, -30, CAST(GETDATE() as date))'
DECLARE #ExpectedRecordsToMove TABLE
(
ExpectedRecordsToMove Int
)
INSERT INTO #ExpectedRecordsToMove
EXECUTE sp_executesql #q
SELECT * FROM #ExpectedRecordsToMove
Note: Answer provided by OP on question.
sp_executesql also allows for output parameters. It is possible to assign variable inside the inner query and return the value.
DECLARE #tblName AS NVARCHAR(MAX) = N'tblAutoDispatch_DispatchStatus_Map_Tracking';
DECLARE #q AS NVARCHAR(MAX)
= N'SELECT #rowcount = COUNT(DateTracked) FROM Audit.' + #tblName
+ N' WHERE DateTracked > DATEADD(dd, -30, CAST(GETDATE() as date))';
DECLARE #rowcount INT;
EXECUTE sp_executesql
#query = #q,
#parameters = N'#rowcount INT OUTPUT',
#rowcount = #rowcount OUTPUT;
SELECT
#rowcount;
You can actually do this without a cursor, by building up the query in one go
You must use QUOTENAME to ensure table names do not cause syntax errors
You cannot parameterize a table name, it must be inserted directly into dynamic SQL
DECLARE #tablenames TABLE (schemaName sysname, tblName sysname);
-- insert schema and table names
DECLARE #sql nvarchar(max) = N'
SELECT
ISNULL(tblName, ''Grand Total'') AS tblName,
SUM(rowcount) AS rowcount
FROM (
' +
(
SELECT STRING_AGG(CAST(
N' SELECT ' + QUOTENAME(tn.schemaName, '''') + N'.' + QUOTENAME(tn.tblName, '''') + N' AS tblName,
Count(DateTracked) AS rowCount
FROM ' + QUOTENAME(tn.schemaName) + N'.' + QUOTENAME(tn.tblName) + N'
WHERE DateTracked > DATEADD(dd, -30, CAST(GETDATE() as date))'
AS nvarchar(max)), N'
UNION ALL
')
FROM #tablenames tn
JOIN sys.tables t ON tn.schemaName = SCHEMA_NAME(t.schema_id) AND tn.tblName = t.name
) + N'
) AS tables
GROUP BY ROLLUP(tblName);
';
PRINT #sql; -- for testing
EXEC (#sql);
If you don't have STRING_AGG on your version of SQL Server, you must use FOR XML instead
It is giving me an error saying 'Incorrect syntax near the keyword 'convert'.' Could not able to figure out what could be done to remove it.
ALTER PROCEDURE [dbo].[sp_convert_unix_timestamp]
#table_name nvarchar(250), ---Staging Table
#DateTimeString nvarchar(max)
AS
BEGIN
if isnull(#DateTimeString,'') <> '' begin
declare #SQLString Nvarchar(max)
declare #UpdateString Nvarchar(max)
declare #initialepoch Nvarchar(10)
set #initialepoch = '19700101'
SELECT #SQLString = coalesce(#SQLString + ',', '') +
'convert(varchar, dateadd(ss, convert(Int, ' + value + '),' + #initialepoch + '), 120)'
FROM STRING_SPLIT(#DateTimeString, ',')
WHERE RTRIM(value) <> ''
select #UpdateString = 'Update [' + #table_name + '] set ' + #SQLString
exec (#SQLString)
end
END
Firstly, let's fix the SP so it's no open to Injection, and the datatype choice for #table_name:
ALTER PROCEDURE [dbo].[sp_convert_unix_timestamp]
#table_name sysname, ---Staging Table
#DateTimeString nvarchar(max)
AS
IF ISNULL(#DateTimeString, '') <> ''
BEGIN
DECLARE #SQLString nvarchar(MAX);
DECLARE #UpdateString nvarchar(MAX);
DECLARE #initialepoch nvarchar(10);
SET #initialepoch = N'19700101';
SELECT #SQLString = COALESCE(#SQLString + ',', '') + N'convert(varchar(10), dateadd(ss, convert(Int, ' + QUOTENAME(value,N'''') + N'), + #dinitialepoch), 120)'
FROM STRING_SPLIT(#DateTimeString, ',')
WHERE RTRIM(value) <> '';
SELECT #UpdateString = N'Update ' + QUOTENAME(#table_name) + N' set ' + #SQLString;
PRINT #UpdateString;
EXEC sp_executesql #SQLString, N'#dinitialepoch nvarchar(10)', #dinitialepoch = #initialepoch;
END;
If we were to run that SP, EXEC [dbo].[sp_convert_unix_timestamp] N'MyTable', N'20170720,20170721';, you'd get this output (and magcially, you know the reason why it's not working):
Update [MyTable] set convert(varchar, dateadd(ss, convert(Int, '20170720'), + #dinitialepoch), 120),convert(varchar, dateadd(ss, convert(Int, '20170721'), + #dinitialepoch), 120)
There is no column in your SET clause. You simply have UPDATE [Table] SET [Value]; The format of an UPDATE statement is UPDATE [Table] SET [Column] = [Value];. What column(s) that needs to be updated, however, I have no idea...
i am getting an error when trying to concatenate date and string.
declare #select varchar(max)
declare #where varchar(max)
set #select = 'select * from tbl Emp........'
#where = ' where Emp.date >='+ cast((cast(getdate() as date)) as varchar(20))
exec(#select+#where)
I also tried to do like below but didn't work:
declare #today varchar(20)
#today = cast((cast(getdate() as date))
#where = 'where Emp.date> =' + '#today'
Try something like this...
declare #select varchar(max)
declare #where varchar(max)
set #select = 'select * from tbl Emp '
set #where = ' where Emp.date >= ''' + CONVERT(varchar(8),getdate(),112) + ''''
exec(#select+#where)
Or an even better option would be something like this.....
DECLARE #Sql nvarchar(max);
DECLARE #Date DATE = GETDATE();
SET #Sql = N' select * from tbl Emp '
+ N' where Emp.date >= #Date'
Exec sp_executesql #Sql
,N'#Date DATE'
,#Date
But why do you even need dynamic sql for this simple query why cant you simply do
DECLARE #Date DATE = GETDATE();
select * from tbl Emp
where Emp.date >= #Date
I want a table with columns named after dates.
example:
SELECT * AS GETDATE() FROM mytable;
From what I've read on the internet, it looks as though I will need to use dynamic SQL (?) something in the lines of this:
DECLARE #dt smalldatetime
SET #dt = GETDATE()
DECLARE #str varchar(100)
SET #str = 'SELECT * AS ' + convert(varchar(100), GETDATE(), 120) + ' FROM mytable'
EXEC(#str);
But this doesn't work. says "incorrect syntax near the keyword 'AS'
All I had to do was change from SELECT * to SELECT [the thing i needed]
DECLARE #dt smalldatetime
SET #dt = GETDATE()
DECLARE #str varchar(100)
SET #str = 'SELECT Item AS ' + convert(varchar(100), GETDATE(), 120) + ' FROM mytable'
EXEC(#str);
this works.
Try this:
DECLARE #dt smalldatetime
SET #dt = GETDATE()
DECLARE #str varchar(100)
SET #str = 'SELECT Item AS '+'''' + convert(varchar(100), GETDATE(), 120) +'''' + ' FROM mytable'
EXEC(#str);
the results look like this but wher the column name says 'Today' I want it to be todays date.
Try this technique:
declare #dt datetime
declare #sql varchar(100)
set #dt = getdate()
set #sql = 'select 1 as [ ' + convert( varchar(25),#dt,120) + ']'
exec (#sql)
In your Case:
declare #dt datetime
declare #sql varchar(100)
set #dt = getdate()
set #sql = 'select 0 as [ ' + convert( varchar(25),#dt,120) + ']'
exec (#sql)
I would return an integer representing a day offset and parse it in the client, failing that you are going to have to use dynamic SQL or do something with the underlying column name itself;;
declare #sql nvarchar(128) = '
select
col1,
col2,
0 as [' + cast(getdate() as nvarchar(32)) + ']
from T'
exec(#sql)
Or
--today
declare #now varchar(32) = cast(getdate() as varchar(32))
--result to temp table
select col1, col2, 0 as [Now] into #T from TheTable
--rename col
exec tempdb..sp_rename '#T.Now', #now, 'COLUMN'
--select
select * from #T
