| Hi all,I am probably making this harder than needs to be but it is hurting my head!I am trying to conditionally selct a line of data from a table with the following logic (obviously pseudo code!):Select * from table where field = "my value" and if "my value" is not there use the value "default value"In actuality "default value" is NULL but i am not sure if this complicates things or not. The table data is set and not for me to change - I am just trying to leverage what is there.Does this make sense? Any help appreciated! |
