Search all tables for multiple values - sql

Question

The below beautiful SP returns the table and columnname and the value
What I am interested in however is to do this search for multiple values.
The only thing I want to know is a distinct output of the table/columnname not the value.
So basically I want to know all tables / columnnames in which my values exist
Then from there I can make a dynamic update query to rename these values in the existing columns ()
So searching these values by making a join maybe would be better.
I also already thought of stacking the entire database in one giant table in which I can then join on a like. But it's a bit of a headache.. any suggestions?
CREATE PROC SearchAllTables
(
#SearchStr 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('%' + #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', '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

It depends on what version of SQL Server you are using and the functionality that exists for parsing text. I mainly use SQL Server 2005 so I am pretty limited, but you can parse #SearchStr and put the values into a temp table and then use that to join back to.
DECLARE #SearchStr nvarchar(100)
SET #SearchStr = N'123|456|789|ABC|DEF|GHI'
IF OBJECT_ID(N'tempdb..#SearchStrings') IS NOT NULL DROP TABLE #SearchStrings
CREATE TABLE #SearchStrings (ID INT IDENTITY, SearchString NVARCHAR(100))
WHILE #SearchStr <> ''
BEGIN
INSERT INTO #SearchStrings (SearchString) SELECT CASE WHEN #SearchStr LIKE N'%|%' THEN LEFT(#SearchStr, CHARINDEX('|', #SearchStr) - 1) ELSE #SearchStr END
SET #SearchStr = STUFF(#SearchStr, 1, CASE WHEN #SearchStr LIKE N'%|%' THEN CHARINDEX('|', #SearchStr) ELSE LEN(#SearchStr) END, N'')
END
SELECT * FROM #SearchStrings
Or you can just parse the values and use them directly.
DECLARE #SearchStr nvarchar(100)
SET #SearchStr = N'123|456|789|ABC|DEF|GHI'
WHILE #SearchStr <> ''
BEGIN
PRINT CASE WHEN #SearchStr LIKE N'%|%' THEN LEFT(#SearchStr, CHARINDEX('|', #SearchStr) - 1) ELSE #SearchStr END
SET #SearchStr = STUFF(#SearchStr, 1, CASE WHEN #SearchStr LIKE N'%|%' THEN CHARINDEX('|', #SearchStr) ELSE LEN(#SearchStr) END, N'')
END

I think I've got it, the purpose was to find all tables in which my values exists and then based on that create multiple update statements to for example add a prefix to the original values, I ended up doing what I suggested that is to stuff the entire database into 2 columns and join on those columns (compared to looping through this query for each value, this happened to be much faster) :
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
alter PROC [dbo].[SearchAllTables]
(
#SearchStr 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('%' + #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
AND TABLE_CATALOG = 'TPV_BE_PRD'
)
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 + ' (NOLOCK) '
)
END
END
END
SELECT distinct ColumnName FROM #Results a inner join OITM b on a.ColumnValue = b."ItemCode" COLLATE SQL_Latin1_General_CP850_CI_AS END
