Query Error - Schema Does Not Exist

Question

I get the following error when creating stored procedure:
Msg 2797, Level 16, State 1, Procedure SearchAllTables, Line 90
The default schema does not exist.
CREATE PROC SearchAllTables

Here is the code from my blog post:
CREATE PROCEDURE spSearchStringInTable
(@SearchString NVARCHAR(MAX),
@Table_Schema sysname,
@Table_Name sysname)
AS
BEGIN
DECLARE @Columns NVARCHAR(MAX), @Cols NVARCHAR(MAX), @PkColumn NVARCHAR(MAX)
-- Get all character columns
SET @Columns = STUFF((SELECT ', ' + QUOTENAME(Column_Name)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE DATA_TYPE IN ('text','ntext','varchar','nvarchar','char','nchar')
AND TABLE_NAME = @Table_Name
ORDER BY COLUMN_NAME
FOR XML PATH('')),1,2,'')
IF @Columns IS NULL -- no character columns
RETURN -1
-- Get columns for select statement - we need to convert all columns to nvarchar(max)
SET @Cols = STUFF((SELECT ', cast(' + QUOTENAME(Column_Name) + ' as nvarchar(max)) as ' + QUOTENAME(Column_Name)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE DATA_TYPE IN ('text','ntext','varchar','nvarchar','char','nchar')
AND TABLE_NAME = @Table_Name
ORDER BY COLUMN_NAME
FOR XML PATH('')),1,2,'')
SET @PkColumn = STUFF((SELECT N' + ''|'' + ' + ' cast(' + QUOTENAME(CU.COLUMN_NAME) + ' as nvarchar(max))'
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS TC
INNER JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE CU ON TC.TABLE_NAME = CU.TABLE_NAME
AND TC.TABLE_SCHEMA = CU.TABLE_SCHEMA
AND Tc.CONSTRAINT_NAME = CU.CONSTRAINT_NAME
WHERE TC.CONSTRAINT_TYPE ='PRIMARY KEY' AND TC.TABLE_SCHEMA = @Table_Schema AND TC.TABLE_NAME = @Table_Name
ORDER BY CU.COLUMN_NAME
FOR XML PATH('')),1,9,'')
IF @PkColumn IS NULL
SELECT @PkColumn = 'cast(NULL as nvarchar(max))'
-- set select statement using dynamic UNPIVOT
DECLARE @SQL NVARCHAR(MAX)
SET @SQL = 'select *, ' + QUOTENAME(@Table_Schema,'''') + 'as [Table Schema], ' + QUOTENAME(@Table_Name,'''') + ' as [Table Name]' +
' from
(select '+ @PkColumn + ' as [PK Column], ' + @Cols + ' FROM ' + QUOTENAME(@Table_Schema) + '.' + QUOTENAME(@Table_Name) + ' )src UNPIVOT ([Column Value] for [Column Name] IN (' + @Columns + ')) unpvt
WHERE [Column Value] LIKE ''%'' + @SearchString + ''%'''
--print @SQL
EXECUTE sp_ExecuteSQL @SQL, N'@SearchString nvarchar(max)', @SearchString
END
GO
IF OBJECT_ID('TempDB..#Result', N'U') IS NOT NULL DROP TABLE #Result;
CREATE TABLE #RESULT ([PK COLUMN] NVARCHAR(MAX), [COLUMN VALUE] NVARCHAR(MAX), [COLUMN Name] sysname, [TABLE SCHEMA] sysname, [TABLE Name] sysname)
DECLARE @Table_Name sysname, @SearchString NVARCHAR(MAX), @Table_Schema sysname
SET @SearchString = N'Cost'
DECLARE curAllTables CURSOR LOCAL FORWARD_ONLY STATIC READ_ONLY
FOR
SELECT Table_Schema, Table_Name
FROM INFORMATION_SCHEMA.Tables
WHERE TABLE_TYPE = 'BASE TABLE'
ORDER BY Table_Schema, Table_Name
OPEN curAllTables
FETCH curAllTables
INTO @Table_Schema, @Table_Name
WHILE (@@FETCH_STATUS = 0) -- Loop through all tables in the database
BEGIN
INSERT #RESULT
EXECUTE spSearchStringInTable @SearchString, @Table_Schema, @Table_Name
FETCH curAllTables
INTO @Table_Schema, @Table_Name
END -- while
CLOSE curAllTables
DEALLOCATE curAllTables
-- Return results
SELECT * FROM #RESULT ORDER BY [Table Name]
It works OK for me.
I also posted another code today which searches a single column in all tables of the database. I spent about an hour working on that code and it works fine for me too.
