How to search for a text in SQL Server Database using Stored procedure

Here is the stored procedure that will search and display the table name and column name of the text you are passing as a parameter to search from the Database.
SQL Query
CREATE PROC SearchTextFromDatabaseTables
(
    @SearchString nvarchar(100)
)
AS
BEGIN
    CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))
    SET NOCOUNT ON
    DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
    SET  @TableName = ''
    SET @SearchStr2 = QUOTENAME('%' + @SearchString + '%','''')
    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', 'int', 'decimal')
                    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

Execute the Procedure using the below query and pass the text to be searched in it.
exec SearchTextFromDatabaseTables 'TEXT TO BE SEARCHED'

and you will get the result as below
    ColumnName                                    ColumnValue
1  [dbo].[TABLENAME].[COLUMNNAME]                SEARCHED TEXT STRING
