Búsqueda de SQL Database [duplicado]

I was wondering if it is possible to search for a string of data in an entire sql database?

i know you can search for certain column headers etc but I need to search for a single string of data and have no idea where in the database (table / column etc ) it will be held.

Is it possible? How would I do this in order to return the column, table or both for where it is held?

cualquier consejo muy apreciado.

(I am using sql server management studio 2005)

Encontré este. Espero eso ayude. -

My best suggestion would be to turn the tables into HTML and to search through there for the data you are looking for. I think you are clear in your question that you want to search data and not metadata. -

Thanks for your directions to other sources. have sorted the issue now. -

You could write a script for that starting with

select *, COLUMN_NAME, TABLE_NAME 
from INFORMATION_SCHEMA.COLUMNS
where TABLE_SCHEMA = 'your_schema'

With that list of tables and columns you can iterate over all of them looking for your input.

This is the script I used in the end. very straight forwards and a great little thing to know.

CREATE PROCEDURE FindMyData_String 
    @DataToFind NVARCHAR(4000), 
    @ExactMatch BIT = 0 
AS 
SET NOCOUNT ON 

DECLARE @Temp TABLE(RowId INT IDENTITY(1,1), SchemaName sysname, TableName sysname, ColumnName SysName, DataType VARCHAR(100), DataFound BIT) 

    INSERT  INTO @Temp(TableName,SchemaName, ColumnName, DataType) 
    SELECT  C.Table_Name,C.TABLE_SCHEMA, C.Column_Name, C.Data_Type 
    FROM    Information_Schema.Columns AS C 
            INNER Join Information_Schema.Tables AS T 
                ON C.Table_Name = T.Table_Name 
        AND C.TABLE_SCHEMA = T.TABLE_SCHEMA 
    WHERE   Table_Type = 'Base Table' 
            And Data_Type In ('ntext','text','nvarchar','nchar','varchar','char') 


DECLARE @i INT 
DECLARE @MAX INT 
DECLARE @TableName sysname 
DECLARE @ColumnName sysname 
DECLARE @SchemaName sysname 
DECLARE @SQL NVARCHAR(4000) 
DECLARE @PARAMETERS NVARCHAR(4000) 
DECLARE @DataExists BIT 
DECLARE @SQLTemplate NVARCHAR(4000) 

SELECT  @SQLTemplate = CASE WHEN @ExactMatch = 1 
                            THEN 'If Exists(Select *

                                          )

                            END, 
        @PARAMETERS = '@DataExists Bit OUTPUT', 
        @i = 1 

SELECT @i = 1, @MAX = MAX(RowId)

    BEGIN
