Find a value anywhere in a database
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.

I have adapted @Ta01's answer so that it doesn't use an sproc, and allows an exact match. Just replace the '' with your string.
DECLARE @SearchStr nvarchar(100) = '<put your string here>'
DECLARE @Results TABLE(ColumnName nvarchar(370), ColumnValue nvarchar(3630))
SET NOCOUNT ON
DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(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 +
' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
)
END
END
END
SELECT ColumnName, ColumnValue FROM @Results

I tweaked Tim Gaunt's solution (which is itself an updated version of the accepted answer) to run on Azure Synapse SQL with its limitations (INSERT...EXEC syntax does not work), as well as a few other minor changes I needed:
DECLARE @SearchStr nvarchar(100) = '%myvalue%'
DECLARE @SchemaName nvarchar(100) = NULL -- Specify a schema name, or NULL to search all tables in all schemas
IF OBJECT_ID('tempdb..#AllResults') IS NOT NULL
BEGIN
DROP TABLE #AllResults
END
CREATE TABLE #AllResults (TableName nvarchar(256), ColumnName nvarchar(128), ColumnValue nvarchar(3630))
SET NOCOUNT ON
DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128)
SET @TableName = ''
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 (@SchemaName IS NULL OR @SchemaName = TABLE_SCHEMA)
AND QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
AND OBJECTPROPERTY(
OBJECT_ID(
QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
), 'IsMSShipped'
) = 0
)
PRINT 'Searching ' + @TableName + '...'
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', 'int', 'decimal', 'bigint')
AND QUOTENAME(COLUMN_NAME) > @ColumnName
)
IF @ColumnName IS NOT NULL
BEGIN

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

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
DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(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))

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

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

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.

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;

For Development purpose you can just export the required tables data into a single HTML and make a direct search on it.

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';

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

It's my way to resolve this question. Tested on SQLServer2008R2
CREATE PROC SearchAllTables
@SearchStr nvarchar(100)
AS
BEGIN
DECLARE @dml nvarchar(max) = N''
IF OBJECT_ID('tempdb.dbo.#Results') IS NOT NULL DROP TABLE dbo.#Results
CREATE TABLE dbo.#Results
([tablename] nvarchar(100),
[ColumnName] nvarchar(100),
[Value] nvarchar(max))
SELECT @dml += ' SELECT ''' + s.name + '.' + t.name + ''' AS [tablename], ''' +
c.name + ''' AS [ColumnName], CAST(' + QUOTENAME(c.name) +
' AS nvarchar(max)) AS [Value] FROM ' + QUOTENAME(s.name) + '.' + QUOTENAME(t.name) +
' (NOLOCK) WHERE CAST(' + QUOTENAME(c.name) + ' AS nvarchar(max)) LIKE ' + '''%' + @SearchStr + '%'''
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
JOIN sys.types ty ON c.system_type_id = ty.system_type_id AND c .user_type_id = ty .user_type_id
WHERE t.is_ms_shipped = 0 AND ty.name NOT IN ('timestamp', 'image', 'sql_variant')
INSERT dbo.#Results
EXEC sp_executesql @dml
SELECT *
FROM dbo.#Results
END

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!
CREATE PROC SearchAllTables

-- Date modified: 28th July 2002 22:50 GMT
CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))
SET NOCOUNT ON
DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
SET @TableName = ''

)
IF @ColumnName IS NOT NULL
BEGIN
INSERT INTO #Results
EXEC
(
'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(CONVERT(varchar(max), ' + @ColumnName + '), 3630)
FROM ' + @TableName + ' (NOLOCK) ' +
' WHERE CONVERT(varchar(max), ' + @ColumnName + ') LIKE ' + @SearchStr2

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'
--------------------------------------------------------------------------------
-- Search all columns in all tables in a database for a string.
-- 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 THESE!
--------------------------------------------------------------------------------
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
--------------------------------------------------------------------------------
-- END SET
--------------------------------------------------------------------------------
set nocount on
declare @TabCols table (
id int not null primary key identity
, table_schema sysname not null
, table_name sysname not null
, column_name sysname not null

)

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.

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
)
