Modify SQL Script to Delete Record

Hello Experts,

I currently have this SQL script that goes through all my tables in the database and deletes the record when it finds the item I specify. It is working well for me so far.
It searches for the field name "ITEMNMBR". But I just found out that the item is also located as a different field name "ITEMNO".
I would like to modify the script to be able to look at both fields for the item.

Thanks

just run the same code with changed columnname one more time:
CREATE TABLE zzResults (
      TableName VARCHAR(100)                                            
)      

EXEC sp_msforeachtable '
IF EXISTS (SELECT 1 FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = PARSENAME(''?'', 1) AND COLUMN_NAME = ''ITEMNMBR'')
            exec (''IF EXISTS(SELECT 1 FROM ? WHERE ITEMNMBR = ''''01AAABBBCCC-XX'''')
                        INSERT zzResults(TableName) VALUES (''''?'''') '') 
            
'
declare @tabname nvarchar(100)
while exists (select top 1 1 from zzResults)
begin
select @tabname = min(TableName) from zzResults
exec ('delete from ' + @tabname + ' where ITEMNMBR = ''01AAABBBCCC-XX''')
delete from zzResults where TableName = @tabname
end
SELECT TableName
FROM zzResults


EXEC sp_msforeachtable '
IF EXISTS (SELECT 1 FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = PARSENAME(''?'', 1) AND COLUMN_NAME = ''ITEMNO'')
            exec (''IF EXISTS(SELECT 1 FROM ? WHERE ITEMNO = ''''01AAABBBCCC-XX'''')
                        INSERT zzResults(TableName) VALUES (''''?'''') '') 
            
'
declare @tabname nvarchar(100)
while exists (select top 1 1 from zzResults)
begin
select @tabname = min(TableName) from zzResults
exec ('delete from ' + @tabname + ' where ITEMNO = ''01AAABBBCCC-XX''')
delete from zzResults where TableName = @tabname
end

SELECT TableName
FROM zzResults

DROP TABLE zzResults

Yes, that's what I have been doing, just hoping there is a way to combine this that way I won't have to change the item 4 times.
If you don't mind, I will wait for other experts to put in their comment.

Thanks

then try like this
CREATE TABLE zzResults (
      TableName VARCHAR(100) ,
      ColumnName varchar(100)
)      

EXEC sp_msforeachtable ' INSERT into zzResults(TableName,ColumnName)  SELECT TABLE_NAME, COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS 
WHERE TABLE_NAME = PARSENAME(''?'', 1) AND COLUMN_NAME in ( ''ITEMNMBR'', ''ITEMNO'') '
SELECT * 
FROM zzResults

declare @tabname nvarchar(100)
declare @colname nvarchar(100)

while exists (select top 1 1 from zzResults)
begin
   Select @tabname = TableName, @colname = ColumnName from ( Select TableName, ColumnName, row_number() over(order by TableName, ColumnName) RowID from 
            zzResults) A where RowID = 1

	exec ('delete from ' + @tabname + ' where ' + @colname + ' = ''01AAABBBCCC-XX''')

	Delete from zzResults where  @tabname = TableName and @colname = ColumnName

end

SELECT * 
FROM zzResults

drop table zzResults

What does it mean to be "Always On"?

you can replace, this works even if your sql version is SQL 2000.

   Select @tabname = TableName, @colname = ColumnName from ( Select TableName, ColumnName, row_number() over(order by TableName, ColumnName) RowID from
            zzResults) A where RowID = 1

with

   Select @tabname = TableName, @colname = ColumnName from ( Select TOP 1 TableName, ColumnName from
            zzResults) A
