21    ** **************************************************************************
22    ** sp_autoformat
23    **
24    ** Generic stored procedure to select data from any table and auto-format
25    ** column's that are of [var]char (string) type (except text) so that these
26    ** column's appear only wide as the maximum-sized data in the table being
27    ** selected from.
28    **
29    ** We also provide for a way to ONLY select a subset of the columns in the
30    ** table. This list can be passed via the @selectlist argument, and should
31    ** be a comma-separated list like what would be used by the user if they
32    ** were doing a normal SELECT from this table. This list should ONLY contain
33    ** the raw column names, and no further expressions around it.
34    **
35    ** The output will be generated in the order that the columns are requested
36    ** via this @selectlist argument.
37    **
38    ** Restrictions:
39    ** =============
40    **
41    **  . Does not fully support use of quoted identfiers for table and
42    **    column names.
43    **
44    **  . The @selectlist is expected to be comma-separated list.
45    **
46    **  . This proc does *not* validate that the columns in the WHERE clause,
47    **    ORDER BY provided by the user actually exist in the table being
48    **    selected from. These are just tacked on to the final SELECT statement.
49    **    If there are errors in these arguments, you will just get a run-time
50    **    error from execute immediate.
51    **
52    **  . The length of the generated SQL statement is max of 2048 bytes. For
53    **    tables with large # of columns, this might overflow. (Provision can
54    **    be made for the caller to supply a SQL buffer in the future.)
55    **
56    **  . There is some support for multi-byte character types but the
57    **    actual reporting of the data is untested.
58    **
59    ** Parameters:
60    **	@fulltabname	- Full table name, possibly 2-, 3-part
61    **	@selectlist	- SELECT list of columns to output.
62    **	@whereclause	- Any WHERE predicates on table.
63    **	@orderby	- Any ORDER BY clause for output.
64    **	@fmtspecifier	- Format specifier to display output, say in XML.
65    **			  (Future extension. Currently only for: 'for xml')
66    **	@trace		- Tracing levels.
67    **
68    ** NOTE(s):
69    ** =========
70    **
71    **  - If the @selectlist is provided, then only these columns will be
72    **    projected out. If not, columns are projected out in colid order,
73    **    just like a 'select *' output.
74    **
75    ** - @selectlist should be formatted as:
76    **
77    **	[  ][ ]*=[ ]*<
78    **
79    **  	. The  is optional.
80    **  	. There can be white spaces around the '=' separator.
81    **
82    ** - This procedure creates a temporary table to store the column information
83    **   for the table being processed. The table is small, but causes space
84    **   requirements on tempdb. Column names of this table has a bit cryptic 
85    **   names - this is to avoid potential conflict with column names of a table
86    **   to process.
87    **
88    ** - If the table being reported on is large-ish, and there are multiple
89    **   'char'-type columns, then the processing could be slightly slow as we
90    **   make as many passes over the input table as there are char-type columns
91    **   to determine each column's max-length.
92    **
93    ** Examples:
94    ** =========
95    **
96    	sp_autoformat systypes
97    
98    	sp_autoformat syscolumns, 'id, colid, name'
99    
100   	sp_autoformat syscolumns, "TableID = id, 'Column ID'=colid, name"
101   			, "where id = 3"
102   ** Trace-levels:
103   ** ==============
104   **	0	- Default; no tracing.
105   **	1	- High-level tracing of major phases.
106   **	2	- Detailed tracing for each phase.
107   **	3	- Dump select-list, as-list at end of each iteration.
108   **	4	- Dump contents of #temp table as it is processed.
109   **
110   **  Trace messages are intentionally left in-line as they are meant only
111   **  for debugging and internal uses.
112   **
113   ** Returns:
114   **	0	- If all processing went ok.
115   **	1	- For usage errors/internal errors.
116   **		- The @@error value that was received when an error occured.
117   **		  This could be the return value from execute immediate.
118   **		  Client can trap this and do further processing based on
119   **		  the error number.
