dynamic sql with datekey - sql

I have the following SQL, however I would like to add a date key to this but been struggling: SQL as follows
SET NOCOUNT ON
DECLARE #Schema NVARCHAR(100) = 'dbo'
DECLARE #Table NVARCHAR(100) = NULL
DECLARE #sql NVARCHAR(MAX) =''
IF OBJECT_ID ('tempdb..#Nulls') IS NOT NULL DROP TABLE #Nulls
CREATE TABLE #Nulls (DataBaseName sysname,SchemaName sysname,TableName sysname, ColumnName sysname,
ColumnPosition int
, NullCount int , NonNullCount int)
select #sql += 'select DBName = '''+ quotename(TABLE_CATALOG)
+''',SchemaName = '''+ quotename(table_schema) +''',TableName = '''
+ quotename(table_name) + ''' , ColumnName = ''' + quotename(column_name)
+ ''' , ColumnPosition = ''' + convert(varchar(5) , ordinal_position)
+ ''' , CountNulls = sum(case when ' + quotename(column_name) + ' is null
then 1 else 0 end) , CountnonNulls = count(' + quotename(column_name) + ')
from ' + quotename(table_schema) + '.' + quotename(table_name) + ';' + char(10)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = #Schema AND (#Table IS NULL OR TABLE_NAME = #Table)
INSERT INTO #Nulls
EXEC sp_executesql #sql
SELECT *,NullCntPercentage = (case when isnull(NullCount,0)=0 then 0 else cast((NullCount*100.0/(NullCount+NonNullCount)) as decimal(15,2)) end)
,NonNullCntPercentage = (case when NonNullCount=0 then 0 else cast((NonNullCount*100.0/(NullCount+NonNullCount)) as decimal(15,2)) end)
FROM #Nulls order by TableName,ColumnPosition
I would like to add the date key using the following
convert(nvarchar(11),getdate(),112)
But been struggling to add this to dynamic sql and not in the output in the second stage which does the percentage
Thank you

Search all String Columns in all SQL Server Tables or Views [duplicate]

Given a number, how do I discover in what table and column it could be found within?
I don't care if it's fast, it just needs to work.
This might help you. - from Narayana Vyas. It searches all columns of all tables in a given database. I have used it before and it works.
This is the Stored Proc from the above link - the only change I made was substituting the temp table for a table variable so you don't have to remember to drop it each time.
CREATE PROC SearchAllTables
(
#SearchStr nvarchar(100)
)

DECLARE #Results TABLE(ColumnName nvarchar(370), ColumnValue nvarchar(3630))
SET NOCOUNT ON

SET #ColumnName = ''
SET #TableName =

SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'

)
END
END
END
SELECT ColumnName, ColumnValue FROM #Results
END
To execute the stored procedure :
EXEC SearchAllTables 'YourStringHere'
If you need to run such search only once then you can probably go with any of the scripts already shown in other answers. But otherwise, I’d recommend using ApexSQL Search for this. It’s a free SSMS addin and it really saved me a lot of time.
Before running any of the scripts you should customize it based on the data type you want to search. If you know you are searching for datetime column then there is no need to search through nvarchar columns. This will speed up all of the queries above.
Based on bnkdev's answer I modified Narayana's Code to search all columns even numeric ones.
It'll run slower, but this version actually finds all matches not just those found in text columns.
I can't thank this guy enough. Saved me days of searching by hand!

This is my independent take on this question that I use for my own work. It works in SQL2000 and greater, allows wildcards, column filtering, and will search most of the normal data types.
A pseudo-code description could be select * from * where any like 'foo'

-- Does not search: image, sql_variant or user-defined types.
-- Exact search always for money and smallmoney; no wildcards for matching these.

declare #SearchTerm nvarchar(4000) -- Can be max for SQL2005+
declare #ColumnName sysname

set #SearchTerm = N'foo' -- Term to be searched for, wildcards okay
set #ColumnName = N'' -- Use to restrict the search to certain columns, wildcards okay, null or empty string for all cols

I don't put it in proc form since I don't want to maintain it across hundreds of DBs and it's really for ad-hoc work anyway. Please feel free to comment on bug-fixes.
I optimized Allain Lalonde answer (https://stackoverflow.com/a/436676/412368).
Numeric values are still supported. Should be roughly 4-5 times faster (1:03 vs 4:30), tested on a desktop with a 7GB database. http://developer.azurewebsites.net/2015/01/mssql-searchalltables/

I have a solution from a while ago that I kept improving. Also searches within XML columns if told to do so, or searches integer values if providing a integer only string.

Thanks for the really useful script.
You may need to add the following modification to the code if your tables have non-convertable fields:
SET #ColumnName =
(
SELECT MIN(QUOTENAME(COLUMN_NAME))
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = PARSENAME(#TableName, 2)
AND TABLE_NAME = PARSENAME(#TableName, 1)
AND DATA_TYPE NOT IN ('text', 'image', 'ntext')
AND QUOTENAME(COLUMN_NAME) > #ColumnName
)

Here, very sweet and small solution:
1) create a store procedure:
create procedure get_table
#find_str varchar(50)
as
begin
declare #col_name varchar(500), #tab_name varchar(500);
declare #find_tab TABLE(table_name varchar(100), column_name varchar(100));
DECLARE tab_col cursor for
select C.name as 'col_name', T.name as tab_name
from sys.tables as T
left outer join sys.columns as C on C.object_id=T.object_id
left outer join sys.types as TP on C.system_type_id=TP.system_type_id
where type='U'
and TP.name in('text','ntext','varchar','char','nvarchar','nchar');
open tab_col
fetch next from tab_col into #col_name, #tab_name
while ##FETCH_STATUS = 0
begin
insert into #find_tab
exec('select ''' + #tab_name + ''',''' + #col_name + ''' from ' + #tab_name +
' where ' + #col_name + '=''' + #find_str + ''' group by ' +
#col_name + ' having count(*)>0');
fetch next from tab_col into #col_name, #tab_name;
end
CLOSE tab_col;
DEALLOCATE tab_col;
select table_name, column_name from #find_tab;
end
==========================
2) call procedure by calling store procedure:
exec get_table 'serach_string';
If you have phpMyAdmin installed use its Search feature.
Select your DataBase.
Be sure you do have selected DataBase, not a table, otherwise you'll get a completely different search dialog.
Click Search tab
List item Choose the search term you want
Choose the tables to search
Another way using JOIN and CURSOR:
USE My_Database;
-- Store results in a local temp table so that. I'm using a
-- local temp table so that I can access it in SP_EXECUTESQL.
create table #tmp (
tbl nvarchar(max),
col nvarchar(max),
val nvarchar(max)
);
declare #tbl nvarchar(max);
declare #col nvarchar(max);
declare #q nvarchar(max);
declare #search nvarchar(max) = 'my search key';
-- Create a cursor on all columns in the database
declare c cursor for
SELECT tbls.TABLE_NAME, cols.COLUMN_NAME FROM INFORMATION_SCHEMA.TABLES AS tbls
JOIN INFORMATION_SCHEMA.COLUMNS AS cols
ON tbls.TABLE_NAME = cols.TABLE_NAME
-- For each table and column pair, see if the search value exists.
open c
fetch next from c into #tbl, #col
while ##FETCH_STATUS = 0
begin
-- Look for the search key in current table column and if found add it to the results.
SET #q = 'INSERT INTO #tmp SELECT ''' + #tbl + ''', ''' + #col + ''', ' + #col + ' FROM ' + #tbl + ' WHERE ' + #col + ' LIKE ''%' + #search + '%'''
EXEC SP_EXECUTESQL #q
fetch next from c into #tbl, #col
end
close c
deallocate c
-- Get results
select * from #tmp
-- Remove local temp table.
drop table #tmp
You might need to build an inverted index for your database. It is assured to be pretty fast.

END
END
END
SELECT

GROUP BY

END
For Development purpose you can just export the required tables data into a single HTML and make a direct search on it.
Suppose if you want to get all the table with name a column name contain logintime in the database MyDatabase below is the code sample
use MyDatabase
SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%logintime%'
ORDER BY schema_name, table_name;
I was looking for a just a numeric value = 6.84 - using the other answers here I was able to limit my search to this
Declare #sourceTable Table(id INT NOT NULL IDENTITY PRIMARY KEY, table_name varchar(1000), column_name varchar(1000))
Declare #resultsTable Table(id INT NOT NULL IDENTITY PRIMARY KEY, table_name varchar(1000))
Insert into #sourceTable(table_name, column_name)
select schema_name(t.schema_id) + '.' + t.name as[table], c.name as column_name
from sys.columns c
join sys.tables t
on t.object_id = c.object_id
where type_name(user_type_id) in ('decimal', 'numeric', 'smallmoney', 'money', 'float', 'real')
order by[table], c.column_id;
DECLARE db_cursor CURSOR FOR
Select table_name, column_name from #sourceTable
DECLARE #mytablename VARCHAR(1000);

There are lots of workable answers already. I just wanted to share one I wrote that has additional functionality.

By far the best and most universal solution I found is to pipe a dump of the db through to a grep of what you are searching for.
e.g. for Mysql:
mysqldump -pPASSWORD database | grep 'search phrase'
Or if you get too many results, you can then output them to a file:
mysqldump -pPASSWORD database | grep 'search phrase' > results.txt

Need all columns on one row

I wrote the following query:
IF OBJECT_ID ('tempdb..#ColumnsType') IS NOT NULL DROP TABLE #ColumnsType
DECLARE #vQuery NVARCHAR(MAX) =''
IF OBJECT_ID ('tempdb..#random') IS NOT NULL DROP TABLE #random
CREATE TABLE #random (
ColumnID INT PRIMARY KEY IDENTITY(1,1) NOT NULL
, randomname VARCHAR(50)
, randomvalue INT)
INSERT INTO #random (randomname, randomvalue)
VALUES ('a3', 123)
, ('bla', 4325)
, ('another_bla', 5643)
, ('end_here', 3)
select *
from #random
CREATE TABLE #ColumnsType (
ColumnID INT PRIMARY KEY IDENTITY(1,1) NOT NULL
, ColumnName sysname
, DataType sysname
)
INSERT INTO #ColumnsType (ColumnName, DataType)
SELECT [name],
system_type_id
FROM Tempdb.Sys.Columns
WHERE Object_ID = Object_ID('tempdb..#random')
AND system_type_id = 56
DECLARE #i INT = (SELECT MIN(ColumnID) FROM #random);
DECLARE #maxId INT = (SELECT MAX(ColumnID) FROM #random);
DECLARE #ColumnName VARCHAR(200);
DECLARE #DataType VARCHAR(200);
WHILE #i <= #maxId
BEGIN
SET #ColumnName = (SELECT ColumnName FROM #ColumnsType WHERE ColumnId = #i)
-- SET #DataType = (SELECT DataType FROM #ColumnsType WHERE ColumnId = #i)
SELECT #vQuery =
'SELECT
MIN(TRY_CONVERT(NUMERIC(30, 4), ' +#ColumnName+ ')) AS ' +#ColumnName+ '_MinValue
, MAX(TRY_CONVERT(NUMERIC(30, 4), ' +#ColumnName+ ')) AS ' +#ColumnName+ '_MaxValue
, AVG(TRY_CONVERT(NUMERIC(30, 4), ' +#ColumnName+ ')) AS ' +#ColumnName + '_AvgValue
, STDEV(TRY_CONVERT(NUMERIC(30, 4), ' +#ColumnName+ ')) AS ' +#ColumnName+ '_StandardDeviation
, SUM(TRY_CONVERT(NUMERIC(30, 4), ' +#ColumnName+ ')) AS ' +#ColumnName+ '_TotalSum
FROM tempdb..#random' -- +#Schema+'.'+#Table+ ''
EXEC sp_executesql #vQuery
PRINT #vQuery
SET #i = #i + 1
END
For the sake of demonstration I create temp table with random values. I perform profiling on part of the columns which are consisting only of numeric values. To filter the columns I get their names and filter by type, using Tempdb.Sys.Columns. In normal case with my original data, I use INFORMATION_SCHEMA.COLUMNS but I think this is not that important.
The query returns the following:
The result is presented on two rows. What I'd like to do is to have this result on one row. The idea is to pivot the one row result after and to receive the following result:
As I mentioned, you need to not use a loop, use a set based method and UNION ALL your dynamic statements. I assume here, as well, that you are using a recent version of SQL Server. If not, you'll need to replace STRING_AGG with the old FOR XML PATH (and STUFF) method.
This should be enough to get you started:
USE Sandbox;
GO
CREATE TABLE dbo.YourTable (Col1 int,
Col2 varchar(10));
GO
DECLARE #SchemaName sysname = N'dbo',
#TableName sysname = N'YourTable';
DECLARE #SQL nvarchar(MAX),
#CRLF nchar(2) = NCHAR(13) + NCHAR(10);
DECLARE #Delimiter nvarchar(50) = #CRLF + N'UNION ALL' + #CRLF;
SELECT #SQL = STRING_AGG(CONVERT(nvarchar(MAX),N'SELECT MIN(') + QUOTENAME(c.[name]) + N') AS ' + QUOTENAME(c.[name] + N'_MIN') + N',' + #CRLF +
N' MAX(' + QUOTENAME(c.[name]) + N') AS ' + QUOTENAME(c.[name] + N'_MAX') + #CRLF +
N'FROM ' + QUOTENAME(s.[name]) + N'.' + QUOTENAME(t.[name])
,#Delimiter) WITHIN GROUP (ORDER BY c.column_id)
FROM sys.schemas s
JOIN sys.tables t ON s.schema_id = t.schema_id
JOIN sys.columns c ON t.object_id = c.object_id
WHERE s.[name] = #SchemaName
AND t.[name] = #TableName
PRINT #SQL;
EXEC sys.sp_executesql #SQL;
GO
DROP TABLE dbo.YourTable;
Here is a very clean and nice solution which is what I was looking for:
I choose the columns, from specific table, scan it once and perform multiple calculations on it
I use dynamic query and make it one statement for all columns.
It works really fast. It took a little over 5 minutes to return result for table with 50 mil rows.
The only thing that is left to do is to UNPIVOT in order to insert results in a table that I want.
DECLARE
#q1 NVARCHAR(MAX)
, #q2 NVARCHAR(MAX)
, #q3 NVARCHAR(500)
, #schema VARCHAR(50) = '' -- choose schema
, #table VARCHAR(200) = '' -- choose table
SET #Q1 = 'SELECT ' + '''' + #table + '''' + ' as tableName, '
SET #Q3 = ' FROM ' + #schema + '.' + #table
SELECT #q2 = COALESCE(#q2 + ', ', '')
+ ' max(' + columnName + ') as ' + columnName + '_max, '
+ ' min(' + columnName + ') as ' + columnName + '_min, '
+ ' avg(' + columnName + ') as ' + columnName + '_avg, '
+ ' stdev(' + columnName + ') as ' + columnName + '_stdev, '
+ ' sum(' + columnName + ') as ' + columnName + '_sum '
FROM (
SELECT s.[name] as schemaName, t.[name] as tableName, c.[name] as columnName, st.[name] as typeName
FROM sys.schemas s
INNER JOIN sys.tables t ON s.schema_id = t.schema_id
INNER JOIN sys.columns c ON t.object_id = c.object_id
INNER JOIN sys.types st ON st.user_type_id = c.user_type_id
WHERE 1=1
AND s.[name] = #schema
AND t.[name] = #table
AND st.[name] IN ('') -- choose columns of specific data type, that you want to profile
) data
SELECT #q1 = #q1 + #q2 + #q3
EXEC sys.sp_executesql #Q1
Enjoy!

Searching for data in all existing tables of a database

I want to search for the date '2017-08-08 09:26' in all existing tables of a database and get the column name and table name of the table that contains that date. So I can find that date in table A in column a.
example: '2017-08-08 09:26' exists in column 'a' of table 'A'
Please give me some suggestions for a solution.
Right now I am using this query in which I can search for columns, but I want to search the data in the columns of the tables in my database.
SELECT
sys.columns.name AS ColumnName,
sys.tables.name AS TableName
FROM
sys.columns
JOIN
sys.tables
ON
sys.columns.object_id = sys.tables.object_id
WHERE
sys.columns.name LIKE '%service%'
You need some good old-fashion dynamic SQL for this:
DECLARE #Sql varchar(max);
SELECT #Sql = STUFF((SELECT 'UNION ALL ' + CHAR(10) +'SELECT '''+
sys.columns.name +''' AS ColumnName, '''+
sys.tables.name +''' AS TableName '+ CHAR(10) +
'FROM sys.tables.name ' + CHAR(10) +
'WHERE '+ QUOTENAME(sys.columns.name) +' = #DateTimeValue ' + CHAR(10)
FROM
sys.columns
JOIN
sys.tables
ON
sys.columns.object_id = sys.tables.object_id
-- type ids: datetime2, smalldatetime, datetime
WHERE sys.columns.system_type_id IN(42, 58, 61)
FOR XML PATH('')
), 1, 11, 'DECLARE #DateTimeValue datetime = ''2017-08-08T09:26:00'';' + CHAR(10))
-- When using dynamic SQL, PRINT is your best friend.
PRINT #Sql
/*
#Sql should contain something like this:
DECLARE #DateTimeValue datetime = '2017-08-08T09:26:00';
SELECT 'Col1' AS ColumnName, 'Table1' AS TableName
FROM sys.tables.name
WHERE [Col1] = #DateTimeValue
UNION ALL
SELECT 'Col2' AS ColumnName, 'Table12' AS TableName
FROM sys.tables.name
WHERE [Col2] = #DateTimeValue
...
*/
-- Unremark only after you've seen what's inside #Sql.
--EXEC(#Sql)
Use the below script for getting entire DB search
DECLARE
#SearchStr nvarchar(100) = 'Pass'
BEGIN
DECLARE #Results TABLE(ColumnName nvarchar(370), ColumnValue nvarchar(3630))
SET NOCOUNT ON
DECLARE #TableName nvarchar(256), #ColumnName nvarchar(128), #SearchStr2 varchar(110)
SET #TableName = ''
SET #SearchStr2 = QUOTENAME('%' + #SearchStr + '%','''')
WHILE #TableName IS NOT NULL
BEGIN
SET #ColumnName = ''
SET #TableName =
(
SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
AND QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > #TableName
AND OBJECTPROPERTY(
OBJECT_ID(
QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
), 'IsMSShipped'
) = 0
)
WHILE (#TableName IS NOT NULL) AND (#ColumnName IS NOT NULL)
BEGIN
SET #ColumnName =
(
SELECT MIN(QUOTENAME(COLUMN_NAME))
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = PARSENAME(#TableName, 2)
AND TABLE_NAME = PARSENAME(#TableName, 1)
AND DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar')
AND QUOTENAME(COLUMN_NAME) > #ColumnName
)
IF #ColumnName IS NOT NULL
BEGIN
INSERT INTO #Results
EXEC
(
'SELECT ''' + #TableName + '.' + #ColumnName + ''', LEFT(' + #ColumnName + ', 3630)
FROM ' + #TableName + ' (NOLOCK) ' +
' WHERE ' + #ColumnName + ' LIKE ' + #SearchStr2
)
END
END
END
SELECT ColumnName, ColumnValue FROM #Results
END

null percentage dynamic sql

I have the following sql:
SET NOCOUNT ON
DECLARE #Schema NVARCHAR(100) = 'dbo'
DECLARE #Table NVARCHAR(100) = NULL
DECLARE #sql NVARCHAR(MAX) =''
IF OBJECT_ID ('tempdb..#Nulls') IS NOT NULL
DROP TABLE #Nulls
CREATE TABLE #Nulls
(
TableName sysname,
ColumnName sysname,
ColumnPosition int,
NullCount int,
NonNullCount int
)
select #sql += 'select TableName = ''' + quotename(table_schema) + '.' +
quotename(table_name) + ''' , ColumnName = ''' + quotename(column_name)
+ ''' , ColumnPosition = ''' + convert(varchar(5) , ordinal_position)
+ ''' , CountNulls = sum(case when ' + quotename(column_name) + ' is null
then 1 else 0 end) , CountnonNulls = count(' + quotename(column_name) + ')
from ' + quotename(table_schema) + '.' + quotename(table_name) + ';' + char(10)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = #Schema AND (#Table IS NULL OR TABLE_NAME = #Table)
INSERT INTO #Nulls
EXEC sp_executesql #sql
SELECT *
FROM #Nulls
However, I would like the database name in the first column, the schema name inn the second and not joined like it currently is and lastly at the end column showing total number of null as a percentage?
Thank you
If you want your code to gather data about tables in all databases on the server, you need to iterate over each database separately:

ColumnPosition int,
NullCount int,
NonNullCount int
)
;
DECLARE #db_name VARCHAR(50) -- database name

Here is another method based on the example posted by ewahner. The big difference is this doesn't use a cursor because you really don't need one for this.
declare #columnName nvarchar(255)
declare #intValue int
set #columnName = 'CustomerId'
set #intValue = 1
declare #DeleteValue varchar(10)
set #DeleteValue = convert(varchar(10), #intValue)
declare #sql nvarchar(max) = ''
select #sql = #sql + 'delete ' + object_name(c.object_id) + ' where ' + #columnName + ' = ' + #DeleteValue + ';'
from sys.columns c
where c.name = #columnName
select #sql
/* Uncomment the line below in order to run */
--exec sp_executesql #sql
Use at your own risk. You will need to uncomment the exec line. But first run it without uncommenting to make sure it gets the tables you want.
declare #columnName nvarchar(255)
declare #intValue int
set #columnName = 'CustomerId'
