| I have a SQL table whose data looks like this:Parm1 Parm2V1 V11V1 V12V2 V21V2 V22V3 V31V3 V32I would like to sort the table, based on a parameter, in the following manner. If the parameter is V1, the table will appear as above. If the parameter is V2, the table will be sorted like this:Parm1 Parm2V2 V21V2 V22V1 V11V1 V12V3 V31V3 V32And, if the parameter is V3, the table will be sorted like this:Parm1 Parm2V3 V31V3 V32V1 V11V1 V12V2 V21V2 V22I have figured out how to make the rows associated with the parameter appear first:SELECT * FROM ( SELECT 1 AS sv, * FROM myTable WHERE Parm1 = @Parm1value UNION SELECT 2 AS sv, * FROM myTable WHERE Parm1 <> @Parm1value ) dtORDER BY svbut I cannot then sort the other rows. Can you please offer some guidance. |
