IM very new to TSQL and am getting my head around stored proceedures etc.
I am using the Code to find a value within one table in my data base, but im not too sure how i would use this code...
Do i need to replace all #* with my relevant table or column name or simply compy paste and execute
Thanks for the help
How do I find a value anywhere in a SQL Server Database?

Well, to answer your question:
First you have to copy the code to a query window an run it.
That will create the stored procedure.
Now you can call the stored procedute by calling:
EXEC SearchAllTables 'a string of your choice'
Note that you will only get hits from text columns (like 'char', 'varchar', 'nchar', 'nvarchar').

Im trying to use a stored procedure to create a pivot table between two declared variables #rvar (as rowvariable) and #cvar (as columnvariable). The point is to call the stored procedure from VBA using these two as dynamic input when executing the stored procedure.
My code has three parts:
creating test-data
declaring locals
finding names of columns in crosstab an storing in new local #sql1
executing crosstable with the pivotfunction using the names stored in #sql1.
My problem: The code below works but I would like to make it dynamic regarding the variable defining the column structure - currently set to "q10_1_resp" - so that I only have to declare the local #cvar and use that in part 3 (like in part 4). I have succeeded in making part 3 into a sql-string with subsequent execution but then the column names stored in #sql1 cannot be used in the code in part 4 (I guess it is a scope thing).
--Part 1
create table [user].[test]
(rowvar nvarchar(max),
q10_1_resp int,
q10_2_resp int)
GO
INSERT [user].[test]
VALUES ('PH',1,2),
('PH',2,3),
('EA',1,5),
('EA',5,4),
('PH',3,4),
('PH',6,6),
('EA',4,1),
('PH',5,3),
('PH',2,1)
GO
-- Part 2
declare #rvar as nvarchar(max) = 'rowvar'
declare #cvar as nvarchar(max) = 'q10_1_resp' --this input should be dynamic as well
declare #sql1 as nvarchar(max)= ''
declare #sql2 as nvarchar(max)= ''
-- Part 3
select #sql1 = #sql1 + [a].[col] + char(44)
from
(select distinct QUOTENAME(q10_1_resp) as [col]
from [user].[test]
group by q10_1_resp) as a
SET #sql1 = left(#sql1, len(#sql1) - 1)
-- Part 4
SET #sql2 = 'select ' +
+ #rvar + ','
+ #sql1
+ ' from (Select '
+ #rvar + ', '
+ #cvar
+ ' from [user].[test]) sq pivot(count('
+ #cvar
+ ') for '
+ #cvar + ' IN ('
+ #sql1
+ ')) as pt'
exec sp_executesql #sql2
After a great deal of trying to globalize the scalarvariable without success using a temporary table to store the string was the key. The temporary table created at the beginning of the stored procedure can be assigned and referenced the entire time of the procedure. Thus assigning within execution of #sql and then referencing the string at execution of #sql2. I hope it makes sense.
CREATE PROCEDURE [dbo].[sp_crosstab]
-- Add the parameters for the stored procedure here
#rvar nvarchar(max) = '',
#cvar nvarchar(max) = '',
#data nvarchar(max) = '',
#sql nvarchar(max) = '',
#sql2 nvarchar(max) = '',
#sql3 nvarchar(max)=''
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
create table #temp_crosstab
(
sqlstr nvarchar(max)
)
set #sql ='
declare #sql1 nvarchar(max) = char(00)
select #sql1 = #sql1 + [a].[col] + char(44)
from
(select distinct QUOTENAME(' + #cvar + ') as [col]
from ' + #data + '
group by ' + #cvar + ') as a
SET #sql1 = left(#sql1, len(#sql1) - 1)
insert into #temp_crosstab values (#sql1)'
execute sp_executesql #sql
select #sql3 = [sqlstr] from #temp_crosstab
set #sql2 = '
select ' + #rvar + char(44) +
#sql3 + 'from (Select '
+ #rvar + char(44) + ' '
+ #cvar
+ ' from ' + #data + ') sq pivot(count('
+ #cvar
+ ') for '
+ #cvar + ' IN ('+#sql3+')) as pt'
exec sp_executesql #sql2

I am trying to create a table that will show me each table name, and the first three characters of the ID column (every table has this column), and then put that data into a table. We are using this to help map dependencies in our Salesforce Org which is replicated onto SQL using dbAMP. I adapted the code below as far as I could, and am looking for help to finish it.
UPDATE: The first half of the question is resolved, and the code now runs to give the first three characters of the ID. I still could use help in converting this code to spool the results into one single table.
USE Salesforce
GO
IF OBJECT_ID('tempdb..#tempResults') IS NOT NULL
DROP TABLE #tempResults
CREATE TABLE #tempResults
(
[Object_ID] VARCHAR(3)
--, [org] VARCHAR(100)
, [Table_Name] VARCHAR(100)
)
DECLARE cur CURSOR FOR
SELECT
'SELECT DISTINCT LEFT(' + QUOTENAME(c.COLUMN_NAME) + ',3) AS
[Object_ID], '''
--+ QUOTENAME(TABLE_CATALOG) + ' as [Org], '
+ QUOTENAME(TABLE_NAME) + ''' as [Table_Name] FROM '
+ QUOTENAME(TABLE_CATALOG) + '.' + QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
FROM INFORMATION_SCHEMA.COLUMNS AS c
WHERE
c.[DATA_TYPE] IN ('nchar','varchar', 'nvarchar')
AND c.[CHARACTER_MAXIMUM_LENGTH] = 18
and c.TABLE_NAME not like '%upload%'
and c.TABLE_NAME not like '%Delta%'
and c.TABLE_NAME not like '%Update%'
and c.TABLE_NAME not like '%Previous%'
and C.COLUMN_NAME = 'ID'

I'm not getting the Column ID trimmed to the first 3 characters, and it's not outputting to a table. I'm not that familiar with cursors so I'd appreciate any help. Thanks,
You're really close. The way you've got your select written it's actually trimming the column name and then appending that 3-character column name to the string, rather than getting the first three characters from the actual data within the ID column.
Try updating your select so the LEFT brackets the QUOTENAME(c.COLUMN_NAME) inside the string, like below. This small change made your script work on my salesforce installation.
SELECT
'SELECT DISTINCT LEFT(' + QUOTENAME(c.COLUMN_NAME) + ',3) AS '
+ QUOTENAME(TABLE_CATALOG + '.' + TABLE_SCHEMA + '.' + TABLE_NAME) + ' FROM '
+ QUOTENAME(TABLE_CATALOG) + '.' + QUOTENAME(TABLE_SCHEMA) + '.'
+ QUOTENAME(TABLE_NAME)
FROM INFORMATION_SCHEMA.COLUMNS AS c
WHERE
c.[DATA_TYPE] IN ('nchar','varchar', 'nvarchar')
AND c.[CHARACTER_MAXIMUM_LENGTH] = 18
and c.TABLE_NAME not like '%upload%'
and c.TABLE_NAME not like '%Delta%'
and c.TABLE_NAME not like '%UPdate%'
and c.TABLE_NAME not like '%Previous%'
and C.COLUMN_NAME = 'ID'
Update to answer part two:
First you'll need a destination table - I've used a temporary table, but this will work just fine as a permanent table.
I've adjusted the code to output two columns instead of one: IDSubstring (your 3-character ID portion) and SourceTable (this is exactly the same information that you were using as a column name previously). This way we know which table the ID portion belongs to.
Then, inside the cursor, instead of just executing, we do this:
INSERT INTO #tempResults
EXEC(#cmd);
This will populate our table and give us selectable values.
CREATE TABLE #tempResults
(
[IDSubstring] VARCHAR(3)
, [SourceTable] VARCHAR(50)
)
DECLARE cur CURSOR FOR
SELECT
'SELECT DISTINCT LEFT(' + QUOTENAME(c.COLUMN_NAME) + ',3) AS [IDSubstring], '''
+ QUOTENAME(TABLE_CATALOG + '.' + TABLE_SCHEMA + '.' + TABLE_NAME) + ''' as [SourceTable] FROM '
+ QUOTENAME(TABLE_CATALOG) + '.' + QUOTENAME(TABLE_SCHEMA) + '.'
+ QUOTENAME(TABLE_NAME)
FROM INFORMATION_SCHEMA.COLUMNS AS c
WHERE
c.[DATA_TYPE] IN ('nchar','varchar', 'nvarchar')
AND c.[CHARACTER_MAXIMUM_LENGTH] = 18
and c.TABLE_NAME not like '%upload%'
and c.TABLE_NAME not like '%Delta%'
and c.TABLE_NAME not like '%UPdate%'
and c.TABLE_NAME not like '%Previous%'
and C.COLUMN_NAME = 'ID'
DECLARE #cmd VARCHAR(MAX);
OPEN cur;
FETCH NEXT FROM cur INTO #cmd;
WHILE ##FETCH_STATUS = 0
BEGIN
--PRINT #cmd
INSERT INTO #tempResults
EXEC(#cmd);
FETCH NEXT FROM cur INTO #cmd;
END
CLOSE cur;
DEALLOCATE cur;
SELECT * FROM #tempResults
Update 2
You're correct in assuming it's an issue with the '''
The ''' is there because we need to build our string with single quotes inside of it.
As examples:
SELECT '' returns nothing
while SELECT '''' returns '
And SELECT 'This is an example''' will return This is an example'
So the ''' are part of a larger string definition started with the initial ' before "This" and can be broken down this way - the first two single quotes are the single quote we want to print within the string and the third single quote is the string terminating quote. If you just run the select statement and look at what it outputs, you can see where each single quote has been inserted into the string.
Updated SELECT is below.
SELECT
'SELECT DISTINCT LEFT(' + QUOTENAME(c.COLUMN_NAME) + ',3) AS [Object_ID], '''
+ QUOTENAME(TABLE_CATALOG) + ''' as [Org], '''
+ QUOTENAME(TABLE_NAME) + ''' as [Table_Name] FROM '
+ QUOTENAME(TABLE_CATALOG) + '.' + QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
FROM INFORMATION_SCHEMA.COLUMNS AS c
WHERE
c.[DATA_TYPE] IN ('nchar','varchar', 'nvarchar')
AND c.[CHARACTER_MAXIMUM_LENGTH] = 18
and c.TABLE_NAME not like '%upload%'
and c.TABLE_NAME not like '%Delta%'
and c.TABLE_NAME not like '%Update%'
and c.TABLE_NAME not like '%Previous%'
and C.COLUMN_NAME = 'ID'
I'm trying to convert the following query to dynamic SQL to allow for variations:
UPDATE T
SET SumCount = J.SUM
FROM #temp T
JOIN (SELECT Count_99221 + COUNT_99222 + Count_99223 [SUM], t2.userID
FROM #temp t2
GROUP BY t2.userID, Count_99221 + COUNT_99222 + Count_99223
) J ON T.userID = J.UserID
This is what I have for the Dynamic SQL:
DECLARE #sql3 nvarchar(2000) =
'UPDATE T ' +
'SET SumCount = J.SumOfColumns ' +
'FROM #temp T ' +
'JOIN (SELECT ' + #columnSumString + ' [SumOfColumns], t2.userID ' +
'FROM #temp t2 ' +
'GROUP BY t2.userID, ' + #columnSumString +
' ) J ON T.userID = J.UserID'
EXEC sp_executesql #sql3
I am receiving the following error only when I run the query as Dynamic SQL:
Each GROUP BY expression must contain at least one column that is not
an outer reference.
Can somebody help explain why this is happening? I am new to Dynamic SQL so I'm not privy to any limitations for running queries this way.
Thank you in advance.
EDIT:
The variable #columnString is a string made by concatenating several other column names, created in the following way:
DECLARE #Cursor Cursor
DECLARE #code varchar(20)
DECLARE #ID INT
SET #cptCursor = CURSOR FOR
SELECT * FROM dbo.Split(#UserInput,CHAR(44))
OPEN #cptCursor
FETCH NEXT FROM #cptCursor INTO #ID, #code
WHILE ##FETCH_STATUS = 0
BEGIN
DECLARE #colName varchar(50) = 'Count_' + cast(#code as varchar(10))
DECLARE #sql nvarchar(50) = 'ALTER TABLE #temp ADD ' + #colName + ' int'
EXEC sp_executesql #sql
--Code that adds values to each column that is created.....
SET #columnSumString = #colName + ' + ' + #columnSumString
--SET #columnSumString = #code + ' + ' + #columnSumString
FETCH NEXT FROM #cptCursor INTO #ID, #code
END
CLOSE #Cursor
DEALLOCATE #Cursor
SET #columnSumString = SUBSTRING(#columnSumString,1,LEN(#columnSumString)-2)
SELECT #columnSumString
The user input is a comma separated string. "Count_99221 + COUNT_99222 + Count_99223" is just one example of columns created from the user input "99221, 99222, 99223".
I also realized I was concatenating the #code variable into #columnSumString instead of #colName. Now when I run the query I don't get the error (even though I don't understand how the above error message relates to that mistake) but every value of SumCount is NULL.
IMHO you must re-write your query as follow:
UPDATE #temp
SET SumCount =
(SELECT Count_99221 + COUNT_99222 + Count_99223
FROM #temp t2
WHERE t2.userID = #temp.userID)
So the dynamic SQL will become:
DECLARE #columnString varchar(200)
SET #columnString = Count_99221 + COUNT_99222 + Count_99223
DECLARE #sql3 nvarchar(2000) =
N'UPDATE #temp ' +
'SET SumCount = (SELECT ' + #columnString +
' FROM #temp t2 WHERE t2.userID = #temp.userID)'
EXEC sp_executesql #sql3
I want to make views from all tables already exist in database that’s hard task to catch the tables one by one and make create view XXXX as select * from Table_name .I find something that it is possible with cursor and the code is :
DECLARE #TableName sysname
DECLARE #ColumnCount INT
DECLARE #ColumnID INT
DECLARE #SelectColumn NVARCHAR(500)
DECLARE #sql NVARCHAR(max) = ''
DECLARE QUERYINFO CURSOR FOR
SELECT
t.name AS TableName,
ccount.ColumnCount,
c.column_id AS ColumnID,
CASE WHEN c.column_id <> ccount.ColumnCount
THEN c.name + ', '
ELSE c.name
END AS SelectColumn
FROM sys.tables t
INNER JOIN sys.columns c ON t.object_id=c.object_id
INNER JOIN (
SELECT object_id,COUNT(*) AS ColumnCount
FROM sys.columns
GROUP BY object_id
) ccount ON t.object_id = ccount.object_id
ORDER BY t.Name,c.column_id
OPEN QUERYINFO
FETCH NEXT FROM QUERYINFO INTO #TableName,#ColumnCount,#ColumnID,#SelectColumn
WHILE ##FETCH_STATUS = 0
BEGIN
IF #ColumnID = 1
BEGIN
SET #sql = 'CREATE VIEW v_' + #TableName + ' AS SELECT ' + #SelectColumn
END
ELSE
BEGIN
SET #sql = #sql + #SelectColumn
END
IF #ColumnID = #ColumnCount
BEGIN
SET #sql = #sql + ' FROM ' + #TableName
EXEC sys.sp_executesql #sql
SET #sql = ''
END
FETCH NEXT FROM QUERYINFO INTO #TableName,#ColumnCount,#ColumnID,#SelectColumn
END
CLOSE QUERYINFO
DEALLOCATE QUERYINFO
but it has error and I don't know how solve it
This is what I would do with dynamic SQL; checking first to see if the view exists, then creating it with all of the columns (not by using SELECT * FROM...).
DECLARE #SQL nvarchar(MAX)
SET #SQL = N''
SELECT
#SQL = #SQL +
N'IF EXISTS(SELECT 1 FROM sys.objects WHERE name = N''v_' + t.name + N''' AND type = N''V'') BEGIN DROP VIEW [v_' + t.name + '] END CREATE VIEW [v_' + t.name + N'] AS SELECT ' +
STUFF(
(SELECT N',' + c.name
FROM
sys.columns AS c
WHERE
c.OBJECT_ID = t.OBJECT_ID
ORDER BY
column_id
FOR XML PATH(''), TYPE).value('.',N'nvarchar(max)')
,1,1,N'')
+ N' FROM [' + t.name + N'];'
FROM
sys.tables AS t
EXEC sp_executesql #SQL
I'm trying to alter multiple SQL Server 2008 R2 tables at one time.
This is my code:
use DatabaseName
go
Declare #SchemaUsed varchar(20) = 'dbo'
create table #Tables
(
TableName varchar(100), Processed int
)
insert into #Tables
select top 1 table_name, 0
from INFORMATION_SCHEMA.TABLES
where TABLE_SCHEMA = #SchemaUsed
and table_type = 'Base Table'
and (TABLE_NAME like 'PM%' )
ORDER BY TABLE_NAME
DECLARE #TableName varchar(max)
DECLARE #SQL varchar(max)
WHILE EXISTS (select top 1 'x' from #Tables where Processed = 0)
BEGIN
SET #TableName = (select top 1 TableName from #Tables where Processed = 0)
Set #SQL = 'ALTER TABLE ' + #SchemaUsed + '.' + #TableName + ' ADD [identityID] bigint IDENTITY(1, 1) NOT NULL '
-- Set #SQL = '''' + #SQL + ''''
Print #SQL
EXEC #SQL;
update #Tables
set Processed = 1
where TableName = #TableName
END
drop table #Tables
I can't get this to work to save my life and get the following error:
Lookup Error - SQL Server Database Error: The name 'ALTER TABLE
dbo.PM1GTVLV ADD [identityID] bigint IDENTITY(1, 1) NOT NULL ' is not
a valid identifier.
I've also tried multiple string variations and using sp_executesql as well.
Can someone point out where I've gone wrong?
Try
DECLARE #SQL NVARCHAR(MAX);
EXEC sp_executesql #SQL;
Instead of EXEC #sql.
As an aside, this is a much more usable version of the same code IMHO:
DECLARE #SchemaUsed VARCHAR(20) = 'dbo';
DECLARE #sql NVARCHAR(MAX) = N'';
SELECT #sql += CHAR(13) + CHAR(10) + N'ALTER TABLE '
+ QUOTENAME(#SchemaUsed) + '.'
+ QUOTENAME(name) + ' ADD [identityID]
BIGINT IDENTITY(1,1) NOT NULL;'
FROM sys.tables
WHERE SCHEMA_NAME([schema_id]) = #SchemaUsed
AND name LIKE 'PM%';
PRINT #sql;
--EXEC sp_executesql #sql;
Or even better:
DECLARE #SchemaUsed VARCHAR(20) = 'dbo';
DECLARE #sql NVARCHAR(MAX) = N'';
SELECT #sql += CHAR(13) + CHAR(10) + N'ALTER TABLE '
+ QUOTENAME(#SchemaUsed) + '.'
+ QUOTENAME(name) + ' ADD [identityID]
BIGINT IDENTITY(1,1) NOT NULL;'
FROM sys.tables AS t
WHERE SCHEMA_NAME([schema_id]) = #SchemaUsed
AND name LIKE 'PM%'
AND NOT EXISTS (SELECT 1 FROM sys.columns AS c
WHERE [object_id] = t.[object_id]
AND c.is_identity = 1);
PRINT #sql;
--EXEC sp_executesql #sql;
To execute a character string, EXEC requires parenthesis around the string (or character variable) as shown in the BOL syntax:
EXEC (#SQL);
