I was looking for a string inside of a table in a massive database.  I was attempting to do this by trial-and-error until I ran across this method which does the searching for me.  This script searches all the text/string type fields in every table in the selected database.  Simply specify the “StringToFind”.

Declare @StringToFind VARCHAR(200), @Schema sysname, @Table sysname, @FullTable int, @NewMinID int, @NewMaxID int,
@SQLCommand VARCHAR(8000), @BaseSQLCommand varchar(8000), @Where VARCHAR(8000), @CountCheck varchar(8000) , @FieldTypes varchar(8000),
@cursor VARCHAR(8000), @columnName sysname, @SCn int, @SCm int
Declare @TableList table (Id int identity(1,1) not null, tablename varchar(250))
Declare @SQLCmds table (id int identity(1,1) not null, sqlcmd varchar(8000))
Declare @DataFoundInTables table (id int identity(1,1) not null, sqlcmd varchar(8000))
