I want to change a specific value at unknown table or column. I reached to the code helped me to search it. I found that at some tables, it's the primary column.
I must do this job because I have a lot of values that need to be changed.
I tried to do the code but I got lot of errors:
Invalid column name 'TableNameA'.
Invalid column name 'ColumnNameA'.
Hope get help as I'm still new for SQL.
What should I do?

I want to write a dynamic sql query to find out the count of missing value for each column from a table. The table comprises of 40 columns and writing missing count for each column is lengthy so can we do it dynamically? I tried to write dynamic query as provided below, but got an error as
Must declare the scalar variable "#sql"
Query:
Declare #sql nvarchar(max)
Declare #columnlist nvarchar(max)
Declare #FieldName nvarchar(max)
set #columnlist = 'Column 1,Column2 ,Column3 ,Column4 ,Column5 ,Column6 ,Column7 ,Column8 ,Column9 ,Column10 ,Column11 ,Column12,Column13'
set #FieldName = 'Column 1,Column2 ,Column3 ,Column4 ,Column5 ,Column6 ,Column7 ,Column8 ,Column9 ,Column10 ,Column11 ,Column12,Column13'
set #sql = 'SELECT COUNT(*)-COUNT(' + #columnlist + ') as '+ #FieldName +'from table_name'
exec (#sql)
Try this:
DECLARE #sql nvarchar(max) = N'SELECT';
DECLARE #table_name nvarchar(256) = N'YourTableName'
SELECT #sql = #sql + ' COUNT(*)-COUNT(' + QUOTENAME(COLUMN_NAME) + ') as '+ QUOTENAME(COLUMN_NAME) + N','
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = N'dbo'
AND TABLE_NAME = #table_name
SET #sql = LEFT(#sql, LEN(#sql) - 1) + ' from ' + #table_name

Allright, so here's an example on how to use something alike to for each column calculate the number of values that have at least one duplicate:
DECLARE #sql nvarchar(max) = N'WITH duplicates AS (SELECT';
DECLARE #table_name nvarchar(256) = N'YourTableName';
SELECT #sql = #sql
+ N' CASE WHEN COUNT(' + QUOTENAME(COLUMN_NAME)
+ N') OVER (PARTITION BY ' + QUOTENAME(COLUMN_NAME)
+ N') > 1 THEN ' + QUOTENAME(COLUMN_NAME)
+ N' END as '+ QUOTENAME(COLUMN_NAME) + N','
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = N'dbo'
AND TABLE_NAME = #table_name;
SET #sql = LEFT(#sql, LEN(#sql) - 1) + ' from ' + #table_name + ') SELECT';
SELECT #sql = #sql
+ N' COUNT(DISTINCT ' + QUOTENAME(COLUMN_NAME)
+ N') as '+ QUOTENAME(COLUMN_NAME) + N','
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = N'dbo'
AND TABLE_NAME = #table_name;
SET #sql = LEFT(#sql, LEN(#sql) - 1) + ' from duplicates';
EXEC (#sql);
You see that it uses 2 SELECT statements, the first creates a CTE that replaces all values that have no duplicate with NULL:
CASE WHEN COUNT([C1]) OVER (PARTITION BY [C1]) > 1 THEN [C1] END as [C1]
The second uses a COUNT DISTINCT to count what is left. Doing it this way, the value NULL will not be counted.
Try this
IF OBJECT_ID('TempDb..#MissingList') IS NOT NULL
DROP TABLE #MissingList
CREATE TABLE #MissingList
(
SeqNo INT IDENTITY(1,1),
TABLE_NAME VARCHAR(255),
COLUMN_NAME VARCHAR(255),

I am looking for a script which finds and replaces all fields of type string within a DB with specified text.
The script would for example take the following parameters:
Search for: null
Replace with: empty-string
The primary string data types in SQL Server: Varchar, NVarchar, Text.
This script would then comb through all string based table data and look for in this case null and replace it with a empty string.
Ok I've put together the following code in the meantime.

As a usage example:
EXEC UPDATE_ALL_COLUMNS '%temp%', 'dbo', '', NULL
Parameters:
#TableNameSearchFilter - this will be used with the LIKE operator to find all the tables from your database whose names that match this value;
#TableSchema - the schema of the table (usually dbo)
#TestValue - the value to search for in ALL of the columns (and rows) of each found table;
#NewValue - the value to replace #TestValue with. Can also be NULL.
Explanation:
The EXEC statement will find ALL tables whose names contain the word 'temp', on the 'dbo' schema of your database, then search for the value '' (empty string) in ALL columns of ALL of the found tables, then replace this value with a NULL.
Obviously, if you have long(er) column/table names or the update value, make sure to update the limits on the parameters.
Make sure to first comment the last line (EXEC (#SQL)) and uncomment the lines with PRINT, just to get an idea for what the procedure does and how the final statements look like.
This is not going to work (most likely) if you want to search for the NULL value (i.e. to have #TestValue as NULL). Nevertheless, it can be easily changed to accomplish this as well, by replacing the equal sign from the WHERE clause (in the dynamic query) with IS NULL and removing the rest of the line, when #TestValue IS NULL.
Can be easily adapted to search for columns of only certain types (like VARCHAR etc).
The procedure accounts for inserting NULL values, and will only do so in NULLABLE columns.
I am using SQL Server 2008. I use to take the script of my data from SQL table using Tasks --> Generate Scripts option.
Here is my problem:
Let's say I have 21,000 records in Employee table. When I take the script of this table, it takes the insert script for all 21000 records. What is the solution if I want to take only the script of 18000 records from the table?
Is there any solution using SQL query or from the tasks wizard?
Thanks in advance...
Create a new View where you select your desired rows from your Employee table e.g. SELECT TOP 21000...
Then simply script that View instead of the Table.
In case the views are not an option for you I wrote the following code based on the Aaron Bertrand's answer here that will give the insert statement for a single record in the db.
CREATE PROCEDURE dbo.GenerateSingleInsert

Calling it could look like the following. You pass in the table name, the table primary key and the where clause and you should end up with your insert statements.
set #whereClause = 'where PrettyColorsId > 1000 and PrettyColorsID < 5000'
exec [dbo].GenerateInserts 'dbo.PrettyColors', 'PrettyColorsID', #whereClause
set #whereClause = 'where Color in (' + #SomeValues + ')'
exec [dbo].GenerateInserts 'dbo.PrettyColors', 'PrettyColorsID', #whereClause
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.

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.

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.

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);
DECLARE #mycolumnname VARCHAR(1000);
OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO #mytablename, #mycolumnname
WHILE # #FETCH_STATUS = 0
BEGIN
Insert into #ResultsTable(table_name)
EXEC('SELECT ''' + #mytablename + '.' + #mycolumnname + ''' FROM ' + #mytablename + ' (NOLOCK) ' +
' WHERE ' + #mycolumnname + '=6.84')
FETCH NEXT FROM db_cursor INTO #mytablename, #mycolumnname
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;
Select Distinct(table_name) from #ResultsTable
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
