<p>Aaron, I liked your code, it solved a problem for me. I ran into a few issues using it (like you said I would) with nulls and the text type so I made some changes to address those issues.</p> <pre><code>ALTER PROCEDURE dbo.GenerateSingleInsert @table NVARCHAR(511), -- expects schema.table notation @pk_column SYSNAME, -- column that is primary key @pk_value INT -- change data type accordingly AS BEGIN SET NOCOUNT ON; DECLARE @cols NVARCHAR(MAX), @vals NVARCHAR(MAX), @valOut NVARCHAR(MAX), @valSQL NVARCHAR(MAX); SELECT @cols = N'', @vals = N''; SELECT @cols = @cols + ',' + QUOTENAME(name), @vals = @vals + ' + '','' + ' + 'ISNULL('+REPLICATE(CHAR(39),4)+'+RTRIM(' + CASE WHEN system_type_id IN (40,41,42,43,58,61) -- datetime types THEN 'CONVERT(CHAR(8), ' + QUOTENAME(name) + ', 112) + '' ''+ CONVERT(CHAR(14), ' + QUOTENAME(name) + ', 14)' WHEN system_type_id IN (35) -- text type NOTE: can overflow THEN 'REPLACE(CAST(' + QUOTENAME(name) + 'as nvarchar(MAX)),'+REPLICATE(CHAR(39),4)+','+REPLICATE(CHAR(39),6)+')' ELSE 'REPLACE(' + QUOTENAME(name) + ','+REPLICATE(CHAR(39),4)+','+REPLICATE(CHAR(39),6)+')' END + ')+' + REPLICATE(CHAR(39),4) + ',''null'') + ' FROM sys.columns WHERE [object_id] = OBJECT_ID(@table) AND system_type_id <> 189 -- can't insert rowversion AND is_computed = 0; -- can't insert computed columns SELECT @cols = STUFF(@cols, 1, 1, ''), @vals = REPLICATE(CHAR(39),2) + STUFF(@vals, 1, 6, '') + REPLICATE(CHAR(39),2) ; SELECT @valSQL = N'SELECT @valOut = ' + @vals + ' FROM ' + @table + ' WHERE ' + QUOTENAME(@pk_column) + ' = ''' + RTRIM(@pk_value) + ''';'; EXEC sp_executesql @valSQL, N'@valOut NVARCHAR(MAX) OUTPUT', @valOut OUTPUT; SELECT SQL = 'INSERT ' + @table + '(' + @cols + ') SELECT ' + @valOut; END </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
